Some symptoms you can see or observe easily, like the involuntary movements called chorea. Or you might hear slurred speech. Other symptoms are a little harder to identify, such as depression or difficulty making decisions. Symptoms of HD are typically divided into three categories: Physical, Cognitive, and Psychiatric. In the following pages, we’ll look at these three categories and ways to address these symptoms from a caregiver’s perspective.
Chorea is dance-like uncontrollable movements and is the most well-known symptom. These movements often cause clumsiness, balance issues, and poor coordination.
- Increased stress or anxiety often make movements worse.
- People with HD are not usually trying to kick or strike a caregiver during personal care, but the chorea can make it appear that way.
- Padding sharp corners or furniture can help prevent bruising.
- People in middle and late stages of the disease are at increased risk for falling. Many use durable medical equipment such as walkers, wheelchairs, bedside commodes, shower chairs, or grab bars to reduce this risk.
- Medications help reduce these movements and it is usually taken between 2 and 3 times a day. The medications are called Xenazine (Tetrabenezine) or Austedo (Detretrabenezine).
- PT/OT can help with balance and strength during the early and middle stages of the disease. During late-stage HD the person is often unable to walk and needs total assistance with transfers.
Swallowing becomes an issue during mid- and late-stage HD. People with HD often cough and choke because the mechanisms involved in this process become weakened. Speech can be slurred and difficult to understand.
- Soft foods, thickened liquids, and increased calories are often suggested by speech therapists.
- Create a safe and distraction free environment for eating. Have the person with HD sit upright at the table rather than in a recliner in front of the TV.
- Encourage small bites and second swallows to clear food from mouth.
- Give plenty of time to finish a meal.
SLOWER THINKING AND DIFFICULTY LEARNING NEW THINGS
With fewer brain cells working at their best, it takes longer to process and retrieve information. As a result, the person with HD may be slower to respond, slower to remember things, have trouble switching to a new topic, and be unable to wait- for anything.
- Ask ONE question at a time and WAIT for a response. It can take more than 10 seconds to process your question, formulate an answer, and coordinate a verbal response. Be okay with silence after you ask a question.
- Using multiple choice or yes/no questions are generally easier than open ended ones.
- People with HD hate surprises so keeping to a predictable routine is easiest.
- People with HD can learn new things, but it will take much longer to retain the information. Routine is important for managing day-to-day events.
- Slower thinking is exhausting. The person with HD may stop mid-task and give up because of the effort it takes to remember the steps. For example, when dressing they may get as far as undergarments and then stop. They will need cueing to continue.
- If the person with HD wants something, do not make them wait if at all possible- this is part of the disease and not their personality.
GETTING STUCK OR PERSEVERATION
Getting stuck on a thought, subject, or idea is very common in HD. The person with HD may ask you the same question over and over, even if you have already answered multiple times.
- Distract the person or redirect them by changing the subject, moving to a different room, offering a favorite snack.
- Use the same phrase to remind them to stop doing something. Some suggestions are: We are done with that
- We aren’t going to talk about that
- Use the time-out hand signal and stop talking
- Remember that this behavior is a symptom and not their personality
ANOSOGNOSIA (Unawareness of Their Symptoms)
A common symptom of HD is lack of awareness of symptoms or problem behaviors. Often people with HD do not notice their movements, balance issues, choking, or mood issues.
- There is no treatment for anosognosia, so the best approach is to be aware of the person’s unawareness.
- Trying to prove to a person with HD they have symptoms is proven not to work and will often make the situation worse.
TROUBLE WITH FACIAL EXPRESSIONS
This symptom is twofold, people with HD have trouble reading someone’s facial expression. They will have a tough time interpreting if someone is happy, scared, angry, or bored. At the same time, the muscles in the face of the person with HD weaken over time, and they have trouble showing emotion. They could be smiling on the inside but appear bored or disinterested.
- Remembering that a person with HD might appear disinterested or grimace, but this is a symptom. You might have to ask how they are feeling and then wait for an answer.
Impulsivity is acting without thinking. Disinhibition is not feeling embarrassed or ashamed. When these symptoms appear, some people with HD lose their temper, drink too much, steal, or have inappropriate sexual relations. This symptom can have extremely negative results for the person with HD and everyone around them.
- These symptoms can be helped with medication from a psychiatrist.
- Try to stay calm and attend to the emotion being expressed by the person with HD. Their hurtful words and actions were likely because of the disease and not their personality.
Depression is quite common in HD and largely due to the HD brain not working properly.
- Medications from a psychiatrist are typically highly effective in reducing depression.
- Keep a consistent schedule and routine. Having structure can help.
- Exercise and time spent outdoors/in the sun can have a positive impact on depression.
Irritability in HD is common. The part of the brain that helps regulate emotions gets damaged and the result can lead to increased irritability. Sometimes it is not obvious what the goal or desired outcome of the outburst is.
- Look for common triggers such as hunger, thirst, pain, exhaustion, change in routine, grief, unplanned events or surprises, or medication changes. Often when these triggers are addressed the irritability is greatly reduced.
- We can’t always control the situation, but we can control how we react. If we react calmly, use a soft voice, and let the person with HD do most of the talking, they will have an easier time calming down themselves.
- The good news is irritability is highly treatable by medications from a psychiatrist.
- Remembering that irritability is a symptom and not part of their personality.
