The June 6th Essential Tremor support group meeting at Holy Cross Hospital in Silver Spring, MD brought together close to 50 members of area Essential Tremor support groups from places like Silver Spring and Columbia, Maryland and Loudoun County and Falls Church, Virginia. There were two speakers preceded by remarks by Peter Muller from HopeNet. Muller informed the audience about what happened last month at a conference HopeNet worked to arrange, held at the National Institute of Neurological Disorders and Stroke (NINDS), a part of NIH. Forty neurologists and ET researchers attended the conference. What they agreed on is that treatment for ET is not possible if they do not know what the condition is. ET presents differently in each person, with varying symptoms such as hand tremors, head tremors, voice tremors, etc., and there can be overlap with other conditions such as Dystonia. These experts decided it would be beneficial to use hand tremors as the focal point to pinpoint what ET is, which suggests there will be upcoming studies.

Moving on, the support group audience was fortunate to hear from Dr. Maguire-Zeiss of Georgetown University’s Department of Neurology who gave a brief overview of the mechanisms in the brain thought to be involved in ET such as the cerebellum, motor cortex and thalamus. There is a question about the role the inferior olive plays as well. Maguire-Zeiss focused on neurons and likened the movement of neurons in the brain to an (electric) circuit and pointed out that if there is a “hiccup in the loop,” that can lead to more body movement (as seen in ET) or less body movement (as seen in Parkinson’s Disease).

Another guest speaker was Dr. T. Sean Vasaitis, Professor of Pharmaceutical Sciences at University of MD, Eastern Shore, who has ET himself and is a practitioner and instructor of the Chen style of Tai Chi. Dr. Vasaitis spoke about body control and elaborated on the benefits of Tai Chi such as reducing stress, releasing tension, improved calm, sleep quality and other cognitive functions. He is exploring the idea of a study on the effects Tai Chi can have on ET patients and speculated that starting out there would be a suggested practice of Tai Chi 2-3 times per week.

HopeNet organized this support group meeting and continues to work toward helping people with ET. Another similar meeting of these support groups is likely to be planned for the fall season, and will again be open to other interested individuals.

We need your help!

We need your help! We want you to help us by contacting the nearest district office of your Congressman or Senator and then meet with them to personally discuss how ET affects you or someone you know.

We have found that the personal touch really helps in these conversations versus the rote “facts” about ET.

Please get in touch with us so we can discuss this further and provide guidance to you on how best to contact the offices.

Please share with your support groups, etc. Thank you for your participation.

Personal Stories – Dale, age 52

Dale’s symptoms started around age 40 when he noticed a tremor when his hands were in motion. It was initially sporadic and he would shake more at times than at other times. By his late 40s the tremor had become worse, he noticed his fingers would tremor, and he believed anxiety and caffeine made it worse, but not always. His left hand was worse than the right. In Dale’s family his father had essential tremor and his sister has it mildly.

Dale saw a neurologist for a diagnosis at the age of 42 and was told it was benign essential familial tremor and it was nothing to worry about health-wise but it could be a nuisance. He was prescribed Primidone which did not work for him. Since then, for 8-9 years, he has been taking Propranolol. He was also prescribed medicine for anxiety which runs in his mother’s family and takes Clonoxopan as needed (hasn’t taken it for a couple of years).

He does not think his ET was a result of any trauma and does not have other movement disorders, but he did experience a softball injury and underwent surgery, had scarring, and then years later a seizure which indicated abnormal electrical activity, but he was told this was not related to his ET. He has no unexplained symptoms that could relate to ET.

Dale does get self-conscious and embarrassed when others see his tremor and while they might be understanding of the condition, they wonder if the shaking means he is nervous. He says his writing is a scribble. He’s been told exercise can help and alcohol can help but knows alcohol is not the solution. He experiences frustration but not depression, counting himself fortunate to look at the bright side of life.

He wonders why there aren’t medicines that really work .. the Propranolol he takes does not work completely.

Speaker Dr. Kathy Maguire Zeiss, Assistant Professor Neuroscience, Georgetown University – Silver Spring Support Group Meeting

Essential Tremor Support Group meeting
Silver Spring, MD
May 2, 2013

Guest speaker: Dr. Kathy Maguire Zeiss, Assistant Professor Neuroscience, Georgetown University

Peter Muller, head of HopeNET, opened the meeting announcing that in June there would be a special Saturday meeting, June 8th at 10am at Holy Cross Hospital, bringing together all local area support groups from this Silver Spring group, the Falls Church VA, and Columbia MD groups, plus the St. Louis support group will teleconference in. Kathleen Welker, the head of Tremor Action Network, will be attending from California,

In introducing our guest speaker, Dr. Maguire-Zeiss, Peter mentioned he recently heard her speak to the Falls Church support group. Being a part of the American Brain Coalition, he thinks having a wider perspective of what’s going on in neuroscience will lead to better treatments for Essential Tremor (ET).

Dr. Maguire-Zeiss mentioned that a large part of the attention in neuroscience goes to Alzheimer’s disease and filled us in on her background that includes working mostly on Alzheimer’s and Parkinson’s disease. What she’s studied she believes is applicable to other diseases where neurons are dying. Her undergraduate degree in biochemistry was followed by graduate school and a PhD at Penn State University. Her postdoctoral training was at the University of Pennsylvania. Her late husband passed away from a brain tumor – in her career she works to study the brain.

She explained the basics to us, that the brain has 4 main cell types that do things involving intention to move, moving, controlling movement, thoughts, and consciousness. The main cell types are split into two groups: glia and neurons. Glia can be broken down into 3 types of cells: microglia, astrocytes, and dendrocytes. The word ‘glia’ in Greek means glue so for the longest time people thought it did what glue does, keeping things in place. We now know each of these cells has a special function and that your brain would not work without them.

Dr. Maguire-Zeiss went on to describe processes of the brain as it relates to movement disorders like ET and her remarks are very much paraphrased as she presented them:

We’re very inventive as scientists, so microglia are the smallest ones, astrocytes look like stars, and these oliodendrocytes make a special protective coating around your neurons to help them function. Neurons are really important because they carry the info you need. They receive process and send information, therefore having a big function. There are a lot of different types of neurons. I like to think of a neuron like a tree in the spring before all the leaves form. You have these main branches and then off of these branches you have the smaller ones. Then you have one large straight branch. This part that looks like a tree without branches (drawing) is where the cell receives its information (dendrites). This is where you process and send information. So we have special names for these.

There’s a tree that has these little protrusions everywhere that later make blossoms, and remarkably dendrites have these little protrusions too and they’re called spines. So there is lots of this everywhere. The spines are areas where other neurons talk to these neurons. This is what you call a cell body. It takes this information and says it has to do something with this, like make a protein or something, and then it sends the information down here to what is called an axon. Each neuron has one axon and that axon goes to wherever it’s supposed to go. So for instance in your brain if you want to move your arm, one neuron will receive information from another part of the brain that says, I want to move my arm, and then it sends that info through these to the cell body. Then this guy sends the message to my spinal cord where it controls my arm. These long axons are really important – the info has to be sent a really long way so they need a lot of energy (just like if you would if you went for a longer run verses a shorter run) which comes from up here (the brain). If this guy’s not healthy you don’t have enough energy for this. So these guys end up coming into this area (they look like little buttons so we call them buttons). Those little buttons come over here and there’s another cell here. The cool thing about the brain is we have between 10 to100 billions of these neurons in our brain. You add these to it, we call them synapses, and we have trillions of these connections in your brain. So these guys (microglia) are all around here doing different things: microglia is like white blood cells that attack a foreign object. There’s a tight barrier called the blood brain barrier wrapped around the brain and you guys probably know that some of the drugs you take will cross or won’t cross that barrier. That’s really important because if you didn’t have that barrier and had a cold. Then all that bacteria would go in your head too and that’s really bad because it’s in this closed space. Because the white blood cells don’t get in there, they’re job is to take care of things that sneak in there. Also, cells die and get damaged: those guys (microglia) are like little pac-men, they chew up and eat debris as they’re moving all the time in your brain. There’s a really cool YouTube video where you can see them moving around. We call that, they “survey”. That’s their main job. What we find is in diseases they do it too much. These guys, the astrocytes, they help support this whole system. The way these guys normally talk to each other (the axon and the spine that’s on the dendrite) is this guy has chemicals that he releases. Then the spine has little receptors for that chemical, specific ones that only bind that chemical – that’s how they talk. But they dump it out into this area, synaptic cleft, dumping those neurotransmitters there. So these cells (glia) take up these neurotransmitters. These guys help to make this work better, they encapsulate it with a protein and lipid combination called myelin, and they insulate this axon. When you insulate something like an electric wire, you can send the electricity signal much faster. And that is what our bodies have done. If they didn’t do this you’d have to have a very big axon to carry all that information. If you’ve ever seen a giant squid – they’re invertebrates without bones and they make these giant, very big axons, thicker than a pencil. If you had to have a hundred billion pencils in your head, how big would your head have to be? So we’ve evolved to have this insulator. So now we know what they look like and how they talk to each other. Then the idea is how they work in your brain. If I took a picture of a brain it looks like this (cross section drawn). If you’re talking about moving since that’s what I’m interested in in the lab, there’s a part of your brain called the motor cortex that helps you with moving. If you map out the motor cortex, there are spaces in here for your feet, knees, arms, trunk, hands (a really big space), and there are spaces for your tongue and your eyes. The ones that have more movement and really precise movement have a larger part of your cortex – for example, your fingers because it takes a lot of effort to move. This is called a homunculus. How do we know that these areas are involved? We’ve done research. If you have a person who’s had a stroke (for every person a stroke is different), it depends on where the stroke occurred and where the blood supply was limited and what died. So if you had a stroke in an area that controls your arms on one side of your brain, then you’ll have someone who has a hard time moving their arm. They will subsequently have to keep practicing and doing things over and over again. So they’ll recover a little bit but probably not completely. This is how we have learned how the brain works. If you want to move your arm, you would have to have info from this area of the brain and it has to get down here to the area of the spinal column that controls the arm. It doesn’t really get interrupted by anything – it is one synapse and one set of neurons that control your crude movement. It’s good in the sense that it’s fast and it’s bad because there’s nothing helping it along the way. If you damage it up here you really have a lot of damage. But remember we have to have information from the outside coming in. For example, to tell you that’s an uncomfortable way you have your legs crossed – so I want to move. We call this sensory information and it comes in a different way but ends up right around the same place and talks back to it to help control it.

So what happens in Parkinson’s or Essential Tremor is all that circuitry going down is functioning okay but what’s not functioning very well is the area in between. So let’s look at the brain this way (drawing). This is the cerebellum. And this is your frontal cortex which controls you from doing dumb stuff .This area is in the middle of the brain acting like a black box and we call it part of the midbrain structures. So what happens in these areas if there’s damage – it’s not like you can’t move it’s just that you’re not moving the way you want to. You either have a tremor at rest, an intention tremor, or one that’s there all the time but worse under those two circumstances. And there are two areas of the brain that control fine movement, for example, if you want to pick up a cup of coffee and bring it to your lips. You guys are all aware of that I’m sure. One area is called the basal ganglia. So if we look at it as an engineer, this is the motor cortex. In order to move it needs another area of the cortex to say, I want to move. It doesn’t just spontaneously move. It needs information. So in this circuit that information comes down to another area deep in the brain here that we give another name to, the striatum. This area has two pathways with both of them ending up in the same place. We call them direct and indirect pathways. They help us to balance what to do and help control the movement. All that information goes into another place involved in Parkinson’s and ET, called the thalamus. That’s your relay center so that’s the area that sends your information back up here to say this is how I want to make the movement – I want it to be a smooth movement, or I want it to be a jerky movement, however I want to have it. And when it doesn’t work that’s when you have movement problems. In Parkinson’s there’s this area of the brain that has a neurotransmitter called dopamine and it controls this. In Parkinson’s those neurons die and because of that Parkinson’s patients aren’t getting the right information to this part of the cortex so they can’t start moving. If you want them to walk and they just hesitate, you have to distract them somehow. There is a trick we can use for the brain to get them to go. If you clap in rhythm they walk in the rhythm of the clap to get started. Another problem these patients face is tremor at rest. Clinical doctors will rate tremors different ways by how fast the tremor is. Most of the Parkinson’s patients who first go to the clinic have already lost a lot of their neurons; about 80% of their neurons have died. The plus is that it’s remarkable they have a little tremor and still have a lot more neurons there than they really need to have normal function. So if we could just diagnose them a little earlier then a lot of the treatments that we know work really well to save those neurons are going to make all the difference in the world for them. So we have lots and lots of people at Georgetown and all over the country looking for what they call biomarkers, ways to know if you have the disease before you have that first symptom. In Parkinson’s we’re getting clues about the rest of the body. What clinicians do is create histories of these patients and what’s come to the surface is that a lot of Parkinson’s patients have REM behavioral sleep disorder way before they have the disease. Normally when you or I are asleep we are paralyzed. We have dreams but we don’t do anything about them. With REM Behavioral Sleep Disorder, you don’t’ have this shutoff so if you’re having a fight in your dream, you’ll punch the person next to you. I guess they just push each other and say, “Hey you’re having a dream”. What they found is that this happens 5-6 years before the tremor. Another thing Parkinson’s patients get way beforehand is constipated. Now you can imagine saying to your physician I’m constipated and him saying, “Oh you have Parkinson’s”. No, he has a list of other things before that. So several groups are looking closer at histories and, are checking people who’ve had a colonoscopy. Looking at biopsies of pre-Parkinson’s patients they have some pathology. There is a certain protein that’s also in the patient’s neurons. So now we’re getting this idea that it’s not just happening in the brain, it’s starting in the gut. We have other types of minor changes when put together look like they have Parkinson’s before they have the disease. That’s really important because it gets at how we can treat these patients with peptides and proteins that can save those neurons. The problem is when we take it to a clinical trial they’ll only allow us to do the trial on patients who have had every other type of treatment. By then there are no neurons for us to save. So we have to change the whole culture about how we do things. That’s one big hurdle I’m sure is the same in every disease we’re trying to study.

In my lab studies, in this whole process I’m asking, what are those glia cells doing. They have to be important in this. What we discovered is that in these areas where neurons are dying, the glia cells are very active and they’re dumping things out into the environment that are killing neurons. So we’re trying to understand that particular pathway and how they get activated. It looks like they get activated by the bad protein that was in the gut that’s also in the neurons. When they release the protein they create bad cells – so we’re trying to block that. So you may have seen news about clinical trials for Alzheimer’s, Parkinson’s, Huntington and ALS where they give them anti-inflammatory drugs that didn’t work very well. It worked well with mice in the lab but not with people. One reason we think is because we’re not getting the right pathway. So we’re trying to narrow that pathway. Another reason is it may not be good to block all your ability to have inflammation because if you have another infection that would be a problem. In Parkinson’s that’s what we think is happening.

In ET, the cerebellum sends info to the thalamus which sends info back to the motor cortex. It’s in this area I think that they believe is where the biggest problem occurs in ET. And there are a couple different types of neurons in this area that are being studied. They are cerebellar neurons: one’s called dentate (they look like teeth) and they send information to another area called Purkinje cells. It’s the cross talk in there that they think is messed up. That’s why some of you may be on a replacement for the neurotransmitter GABA, because that’s the neurotransmitter that talks to these two. Again, if there’s an interruption here, then if you get to the motor cortex you can no longer have normal movement. The job of this guy (GABA) is to prevent a lot of movement. Without it there to dampen it, you don’t have any control of your thalamus so it wants to move all the time. It’s the loss of really good control that gives you the tremors. Another disease you may have heard of is Huntington’s disease – they are moving all the time and it’s dramatic. Once you’ve lost control of this major relay center then you’ve lost all your fine movement.

So how do we study this better? We’re good at a couple of things: looking at a specific neuron under a microscope, or growing them in mice. We can even put an electrical probe in them and understand how they talk to each other. So we’re good at one cell measurement. Another thing is we’re able to do pretty well are functional MRIs – where you’re in a scanner and we ask you to do something or show you something. We can see what areas of the brain light up when you’re doing or thinking of a specific task. In fact that’s how they figured out that in the motor cortex there’s info needed before you make a movement. They had patients in the MRI do a specific routine of finger movement and two areas of the brain lit up when thinking about the task and doing the task. Then they had them just think about the task. So what does it mean when it lights up in the MRI? When we’re trying to figure out what area of the brain does something it’s usually some kind of compound that gets converted to glucose – because your brain needs a lot of energy. Your brain is pretty small compared to the rest of your body but it uses 20% of the energy of the body, it uses a lot of glucose. What we’re not good at is understanding what that means. If you had an MRI and you had a memory test one area might light up. There’s this guy named Brodmann and he mapped the whole brain. There are 42 Brodmann areas and each one is related to some task. Your temporal lobe is the area for memory. If it lights up, it tells us some neurons there are important. But we don’t know what’s in the whole group of neurons. The only way to know is to look at postmortem tissue and use all these different techniques and it would take a really long time. So that’s where the Obama Brain Initiative comes in, they decided we need to understand how all these areas of the brain are talking to each other. They want to map the brain. What they plan to do is understand the connections. We’ll start with animal models. One example of what they’ve done so far is a technique called Clarity. You take a mouse brain and it looks very pink and you can’t see through it. There’s lots of tissue as the brain is made up of cells and a lot of fat. They took the mouse’s brain and put it through a couple of chemical baths. Afterwards you could see through it. They got rid of all the fat and you could see all the cells still in suspension in the brain. It’s the most amazing thing. What’s the beauty of that? Well we have a lot of techniques that will allow us to look at certain sets of neurons because we can make certain neurons different colors. Plus we can see where they go in 3 dimensions. So this is an example of the power that can come out of this Brain Initiative. Another technique developed by this researcher involved using two different mice. When mated he got a mouse whose neurons in one specific area were a certain color. He could knock out genes or stop them from being expressed. So this is very powerful. So this initiative should hopefully make a big difference. Even when you have critics saying you’ll only get a little information, I’d say it’s better to get a little information than none.

A question was posed as to whether there are indicators for ET that are similar to the ones found in the gut for Parkinson’s. Dr. Maguire-Zeiss said she doesn’t think so but wants to show us something about that process and why that’s important. In PD they have a protein called alpha-syncline which has been linked to familial disease. So there are a small group of patients that have a mutation in this gene, and they go on to have Parkinson’s. So once we knew this protein was involved, the field exploded and people did everything they could with this protein. This protein is small and it doesn’t have any structure to give it its function. This is very unusual. We made knockout mice that never had it. As not losing this protein did anything, it must have been a gain of toxic function. So then people started investigating how that can be. And what we noticed was in PD the neurons under a microscope had these things that looked like perfect circles in these neurons. They named it after the person who found it, a Lewy body (see black circle in picture of cell with nucleus).

When they found out about this mutation, they wondered if the alpha-syncline protein was in the lewy body and sure enough it was. So labs have been studying the protein lewy body. It aggregates into a very large protein, and when that happens the cell starts to die. This happens in the peripheral nervous system that innervates the gut in a subset of Parkinson’s patients. So there are a group of patients with PD that have this lewy body pathology but I don’t think everyone does. I’ll give you my opinion but it’s not Georgetown’s opinion. What we’re finding in the PD patients: they aren’t all the same. They might have more of a tremor in their hands but less problems initiating movement, or they could have a less severe tremor but have more memory problems. It’s wrong to group people together because then the therapies will become the same, and they can’t be because you’re going to have different types of tremors. I think you’re going to have the same thing with ET. People have tremors in different areas and are more or less responsive to different drugs. I recommend that you advocate with your physician to see if you fit in this bin with everyone else or is there something extra that needs to be done.

We have found that we have this huge amount of microglia and then we get inflammation. We know this from imaging studies of Parkinson’s patients. There’s a specific thing you can put in the blood that microglia will bind to. What they see in Parkinson’s patients is when there is death of neurons in one specific area the whole brain starts to light up, and there’s inflammation. The same thing happens in Alzheimer’s disease. So that’s why we think this is an important link between many diseases. What we found is one particular structure that activates. Normally this small protein is found in the cells, that does not activate the microglia. So this structure has to be this one. We hope that as we get more data and work with other labs that are working to develop compounds to block the inflammation that it’ll be, not a cure, but an adjunct therapy to whatever patients are already having. We want to keep the immune response down because it’s really damaging other cells in the area.

Peter Muller said there are two areas you can donate your brain: Columbia University and University of Arizona. They’re taking different approaches. What’s been interesting is that Columbia has found lewy bodies in ET and Arizona has not. It may be because Columbia is getting older brains. Dr. Maguire-Zeiss said studies have been done on microglia in mice. If we find something interesting, we go to human tissue. You have to wait before using human tissue until you are almost 100% sure. It’s so hard to get human tissue. Georgetown gets brains from Columbia & Harvard. The problem is not so much the diseased brains but control brains.

Clinical neurologists have a lot of pressures such as insurance issues and pressures to see a certain number of patients. If they don’t, they won’t have a job for long. So this is a problem. And I think the brain initiative will only probably occur at a few unique places to start with – where they get support from both the hospital that they work in and a closely aligned university. What comes to mind is a program we’re starting, not that we’re the only ones. We have PhD students mostly in our program. I’m in the program called the Interdisciplinary Program for Neuroscience at Georgetown University. We like it because neuroscience is interdisciplinary. So we have biochemists, cell biologists, pharmacologists and neuroscientists and we all work together and it’s great. What we’ve designed at Georgetown is a track where you get a translational medicine certificate because we can’t really do a degree in it yet. So you do your PhD for instance in our department, neuroscience. Normally you would take a bunch of didactic courses, which are the core of neuroscience. You still do that. In your second year, where students would take electives they are really interested in, they do translational med – courses on how to do clinical research and design clinical experiments. Then when they get to their thesis normally they come to my lab and have a mentor who’s a clinician interested in bridging the clinical basic research. The research that we do is patient-based research with my (neuroscientist) basic science input. We’re trying this new program because we’re seeing that we we’re missing the gap. We’re getting a lot of basic scientists, a lot of clinicians, and very few MD, PhD’s because it’s a hard road and a lot of times the PhD work goes back to the very basic so they don’t get to translate. This is supposed to start next year. We’re pretty excited about it. You can do it in anything so if you’re a cancer biology PhD you can still do the translational stuff. In that case, your mentor would be someone in the Lombardi Cancer Center. The environment is hard for scientists because we have to get our own money to do our work. This new generation doesn’t want to face that. They don’t want to work 60 hour weeks for not a lot of money so it’s hard to get them excited. They’re excited in high school but they get burnt out somewhere along the way.

What Physical Therapy Can Do To Help You With Balance If You Have ET

We had our Falls Church support group meeting at Little River Glen Senior Center March 14, 2013. Our speaker was Jordan Tucker, DPT, Fair Oaks Hospital, Outpatient Clinic.  Below are notes and handouts from that presentation.

Balance is often a problem for people with ET.  Decreased strength and flexibility, which often come with ET, can adversely affect balance.  Flexibility is important because the ability to stretch one’s leg, calf, and chest muscles affects balance.   Similarly, lack of strength to easily get out a chair can result in falls.  Scoliosis and gait issues may make the body lean in one direction, throwing you off balance.  ET sufferers also have more trouble dual tasking, i.e., walking and talking or walking in one direction and looking in another.  Ankle instability, high or low arches, knee or gait issues, weak ankles, and hip problems also affect balance.  Physical therapists work with patients to deal with all these problems.

Physical therapists experienced in working on balance with patients who have neurological issues tend to be found in hospitals.  Call your local hospital to see if they offer it.  Be aware that, if you are on Medicare, there is an $1800 cap on PT.  However, there are exceptions to this limit, such as a change in your diagnosis or treating multiple problems.

Physical therapy involves an initial evaluation followed by a plan for exercises done with the therapist and a plan for exercises to do at home.  The course of treatment will take place twice a week for two weeks or longer.  It typically involves stretching, strengthening specific muscles as needed, and balance exercises.  You can get a prescription for physical therapy from any doctor – your primary care physician as well as a neurologist. Just ask.

Physical therapy can retrain the three systems that have to do with balance:

  • Eyes and vision – cataracts can be a problem affecting balance
  • Feet – neuropathy (pain and tingling in extremities) interferes with the feedback from your feet that helps maintain balance
  • Brain – reaction times

Tai chi, yoga, Pilates, and water therapy are also useful in improving balance.  Jordan Tucker suggested joining a community exercise group.  She also said that people with ET and balance problems may benefit from using a cane, a walker, or walking sticks.

An audience member said that he uses walking poles successfully.  They are available in sporting goods stores, but the poles in sporting goods stores tend to have narrower rubber tips than the ones sold online for balance.  He found information about poles at http://polesformobility.com/ and https://www.exerstrider.com/product-category/poles/.  The poles are pictured below (but picturing smaller tips than those used by the audience member).

Jordan Tucker handed out a questionnaire on balance confidence and a home safety checklist with tips on using stairs, railings, grab bars, and avoiding reaching for far-away objects (which we may do in the kitchen).    Some obvious points are often overlooked, such as the need for good lighting in the home, especially near stairs. Night lights in the bathroom can be useful, too.

St. Luke’s Support Group Notes – January 5, 2013

The St. Luke’s Support Group met on Saturday, January 5th at 10:30 AM, when Dr. Mark Hallett spoke to us via video conferencing.  Dr. Hallett gave us a good description of essential tremor confirming the idea that it is probably a group of disorders.  It affects different people in different ways as do the treatments. We learned that there is a very real difference in how the medications and treatments affect (or don’t affect) each individual.

Due to the nature of the condition, there is no reason to give up and not try another treatment just because the first does not work.

Dr. Hallett also told us of some of the research that is being done, including their ongoing attempts to get a pharmaceutical firm to make a prescription drug of Octanoic Acid.

He answered many questions and very graciously agreed to speak to us again in the future.

My own personal note at the end of the meeting was to remind everyone that the purpose of HopeNET is two-fold: To create awareness of ET and to fund research.

Despite snow flurries, the meeting was well attended.
