Has anyone in your family or someone you know suddenly started acting strangely? Perhaps their limbs are twitching uncontrollably? Or is their memory slowly fading, and they seem to be losing their former vigor? It's normal to feel scared when we see things like this. Today we're going to talk about a condition that can cause these symptoms, but is not talked about much in society. That is Huntington's disease . Don't be alarmed when you hear this name. Let's talk about everything simply and clearly.
Okay, so what is Huntington's Disease?
Simply put, Huntington's disease is a genetic disease that causes the nerve cells in our brain to gradually die over time, and is passed down from generation to generation . It mainly affects the parts of the brain that control our movements, thinking, and behavior.
This leads to a decline in motor skills, thinking and decision-making abilities over time, and an increased risk of developing mental health problems such as depression and anxiety.
Symptoms usually begin to appear between the ages of 30 and 40. However, sometimes the disease can begin in childhood or young adulthood, before the age of 20. In that case, we call it Juvenile Huntington 's Disease (JHD) .
There is currently no cure for Huntington's disease. But don't worry. There are many effective treatments to help manage symptoms and reduce the discomfort they cause. And there are many things you can do to live a better life with this condition.
Why does this disease occur? How is it inherited?
This is caused by a defect in one of our genes. In 1993, scientists discovered the gene that causes this. This gene is present in all of us. However, some families may have a mutated copy of this gene. That mutated gene is passed from parents to children.
Imagine that either your mother or your father has Huntington's disease. If so, you have a 50% chance of inheriting the mutation that causes the disease. It's like flipping a coin. You may or may not get it.
- This mutant gene can be inherited regardless of gender.
- If you don't have the mutated gene, you will never develop Huntington's disease. And you won't pass the disease on to your children.
- This disease does not skip generations . That is, if the father has it, the son cannot develop it without the father.
Is this gene dominant or recessive?
It's very simple. Imagine that you have two genes, one from your mother and one from your father. A 'dominant' gene is like the smartest kid in class. If he's there, his power is in play. The mutant gene that causes Huntington's disease is also a dominant one . So even if you get the mutant gene from just one parent, it's enough to cause the disease.
If you or someone in your family is considering genetic testing, it is important to first seek genetic counseling. They can explain to you what to expect from the test results.
What are the symptoms of Huntington's disease?
The symptoms of Huntington's disease can be divided into three main categories: motor skills, cognitive function, and behavioral . These symptoms usually do not appear all at once, but develop gradually over several stages.
| Type of symptom | Early-Stage Symptoms | Middle-Stage Characteristics |
|---|---|---|
| Motor | Uncontrolled jerking movements of the face, arms, and legs (chorea) . Discomfort, loss of balance. Slowing of eye movements. | (chorea) worsening condition. Difficulty walking. Dropping objects, frequent dragging. Difficulty speaking and swallowing. |
| Thinking ability (Cognitive) | Difficulty multitasking. Forgetting things (e.g. appointments). Difficulty learning new things. Difficulty making decisions. | More confusion. More memory loss. Clearly reduced ability to think. Inability to organize things. |
| Behavioral and Psychological | Depression, anxiety. Thinking or saying the same thing over and over again. Getting angry easily. Insomnia and loss of body energy. | Major personality changes. Thoughts of death or suicide. Weight loss. Emergence of conditions such as (OCD) or (Bipolar disorder) . |
Late-Stage Symptoms
At this stage, the patient requires assistance from others to perform tasks. Walking and talking may stop completely. However, even at this stage, the patient is often able to recognize their loved ones.
How to diagnose this disease?
If you have symptoms, your doctor will ask about your family medical history and do a physical exam. They will then likely order some neurological tests and a genetic test. Neurological tests look for:
- Reflexes
- Muscle strength
- Balance
- Vision and Hearing
- Mood and mental state
- Memory and reasoning ability
The sooner the disease is diagnosed, the easier it is to maintain a good quality of life for longer. You may also have the opportunity to participate in new research and clinical trials.
Treatment methods and management
Although there is no complete cure for this yet, there are many treatments that can control the symptoms and make life easier. It's not for nothing that doctors say, "We can't add years to your life, but we can add life to your years."
The most important thing is to seek the help of a team of specialists from various fields. This team may include neurologists, physical therapists, occupational therapists, speech therapists, psychiatrists, and nutritionists.
Medications
- For movement control: Drugs from the VMAT2 inhibitor class (e.g. Deutetrabenazine, Tetrabenazine) are used to reduce uncontrolled movements (chorea).
- For mental health problems: Various antidepressants and mood stabilizers are prescribed to control depression, anxiety, and other mood swings.
Therapy
- Physical Therapy: Helps reduce falls by improving gait, balance, and body strength.
- Occupational Therapy: Teaches techniques and equipment to make daily tasks like eating and dressing easier.
- Speech Therapy: Helps with speech and swallowing difficulties.
Changes in lifestyle and nutrition
People with this disease may lose weight because their bodies burn a lot of calories and have difficulty swallowing. Therefore, it is important to eat nutritious, high-calorie foods . Family members can help with this by:
- Avoid unnecessary interruptions during meals.
- Choose foods that are easy to chew and swallow.
- Use specially designed cutlery and cups with straws.
- Regular exercise is also very important. But you need to be careful about safety. Talk to an experienced physical therapist and develop an exercise plan that suits you.
Questions to ask your doctor
If you or a family member is concerned about this condition, you can ask these questions when talking to your doctor:
- Doctor, how will this disease affect my life?
- What are the best treatments for my symptoms?
- Could this treatment conflict with other medications I am taking?
- Is it safe for me to continue driving?
- How do I want to talk to my family about this?
Take-Home Message
- Huntington's disease is a genetic disease that is passed down from generation to generation. If a parent has the disease, there is a 50% chance that a child will inherit it.
- Although there is currently no complete cure for this, there are very effective treatments to control symptoms and improve quality of life.
- Early detection is important, as symptoms can be better managed.
- It is essential to build a strong support system consisting of specialist doctors, therapists, and family members.
- Psychological problems such as depression and anxiety can commonly occur with this disease, and treating them is just as important as treating physical symptoms.
- New research is constantly being conducted on this topic, so stay hopeful. Stay in touch with your doctor.
