What is Huntington’s disease?
Huntington’s disease is a condition that gradually prevents parts of the brain from functioning properly. It can affect both men and women equally and is inherited from parents. The disease is usually fatal within approximately 20 years.
What are the symptoms of Huntington’s disease?
Symptoms typically begin between the ages of 30 and 50, though they can start earlier. Common symptoms include:
Difficulty concentrating and memory problems.
Depression.
Frequent tripping or falling.
Involuntary movements or limb/body stiffness.
Mood swings and personality changes.
Trouble with swallowing, speaking, and breathing.
Difficulty with movement.
What causes Huntington’s disease?
The disease is brought on by a genetic defect that causes progressive damage to particular brain regions. Given that it is inherited, if one parent is affected:
There is a 1 in 2 chance (50%) that the child will inherit the faulty gene and develop the disease, which they may then pass on to their children.
There is a 1 in 2 (50%) chance that the child will not inherit the disease at all. Children who are not affected cannot pass the condition to their own children.
How is Huntington’s disease diagnosed?
If there is a family history, especially if a parent or grandparent has been diagnosed. A genetic test can be done to assess the risk. This involves examining a blood sample to identify the faulty gene causing the disease. It may take several weeks to receive the results.
What are the treatment options for Huntington’s disease?
Currently, there is no cure or way to slow the progression of the disease. However, several interventions may help manage the symptoms:
Medications for depression, mood swings, and involuntary movements.
Speech and language therapy to help with swallowing and communication issues.
Physical therapy to support movement and balance.
Occupational therapy to assist with daily tasks.
Can Huntington’s disease be prevented?
As a genetic disorder, it cannot be prevented if the gene is inherited. However, if there is a family history, genetic counseling may be helpful before deciding to have children.
What are the complications of Huntington’s disease?
Difficulty speaking clearly.
Swallowing problems that may lead to choking or aspiration pneumonia.
Increasingly slow movements.
Changes in personality.
Breathing difficulties.
Progressive loss of mobility, potentially resulting in the inability to walk or sit independently.
When should I see a doctor?
Speak to your doctor if:
You are concerned about symptoms that might be related to Huntington’s, especially if a family member is affected.
You have a family history and want to know your risk.
You have a family history and are planning to become pregnant.
Frequently Asked Questions:
How do I know if I carry the gene?
A genetic test can detect whether you carry the faulty gene that causes Huntington’s disease. Not everyone at risk chooses to take the test, and it may or may not be the right choice for you.
I have a symptom of Huntington’s but no family history. What does this mean?
Huntington’s is typically inherited, so it is uncommon to develop the disease without a family history. However, if you are concerned, document your symptoms and speak with a doctor. You may be referred to a specialist (usually a neurologist) for evaluations, which might include basic clinical exams and brain imaging to rule out other similar conditions.
