Huntington’s disease is a genetic disorder that affects the brain, leading to dementia and other neurological symptoms. It is caused by a mutation in the huntingtin gene, which leads to the accumulation of a toxic protein in the brain.
This protein damages the nerve cells in the brain, leading to a range of cognitive, emotional, and movement problems.
Symptoms of Huntington’s Disease Dementia
The symptoms of Huntington’s disease dementia can vary widely from person to person and depend on the stage of the disease. The earliest symptoms of HD could be subtle and easy to miss. The symptoms become more obvious as the disease progresses.
Cognitive Symptoms.
The most common cognitive symptoms associated with HD include:.
- Difficulty with planning, organizing, and problem-solving
- Forgetfulness and memory problems
- Difficulty with decision-making and reasoning
- Difficulty with attention and concentration
- Difficulty with learning and retaining new information
Emotional Symptoms.
HD can also affect a person’s emotions and behavior. The most common emotional symptoms include:.
- Depression and anxiety
- Irritability and mood swings
- Agitation and restlessness
- Apathy and social withdrawal
- Lack of motivation and interest
Movement Symptoms.
The hallmark symptom of HD is a movement disorder. The most common movement symptoms associated with HD include:.
- Involuntary movements, such as chorea, which includes jerky, dance-like movements
- Tremors and muscle rigidity
- Difficulty with walking and balance
- Slurred speech and difficulty with swallowing
- A slowing of voluntary movements, such as blinking and moving the arms or legs
Diagnosis of Huntington’s Disease Dementia
There is no single test that can diagnose HD, and diagnosis is often made based on a person’s symptoms and family history.
A doctor may conduct a neurological exam, which includes testing a patient’s coordination, reflexes, balance, and other functions of the nervous system.
Genetic testing can also be used to diagnose HD. A blood test can determine whether a person has the mutated huntingtin gene, which causes the disease.

However, some people who have the mutation may not develop symptoms for several years, so this test alone may not be enough to diagnose HD.
Other tests, such as brain imaging and cognitive testing, may also be used to diagnose HD. A doctor may use imaging tests, such as MRI or CT scans, to detect changes in the brain that are associated with HD.
A cognitive test may be used to assess a patient’s cognitive abilities and determine whether there are any signs of dementia.
Treatment of Huntington’s Disease Dementia
There is no cure for HD, but there are treatments that can help manage the symptoms of the disease. Treatment may be focused on addressing cognitive, emotional, and movement symptoms.
Cognitive Treatments.
Cognitive treatments for HD may include medications to help with memory and other cognitive functions. There are also cognitive therapies that can help with problem-solving, decision-making, and other cognitive skills.
Emotional Treatments.
There are a range of emotional treatments that may be used to treat the emotional symptoms of HD. These may include medications to help with depression and anxiety, as well as psychotherapy to address emotional and behavior issues.
Movement Treatments.
Treatments for movement symptoms of HD may include medications to help control involuntary movements, as well as physical therapy to improve muscle strength and coordination. In some cases, surgery may also be used to control involuntary movements.
Conclusion
Huntington’s disease dementia is a difficult and progressive disease that affects many aspects of a person’s life. However, there are treatments available that can help manage the symptoms of the disease and improve quality of life.
Early diagnosis and treatment can be critical to managing HD, so if you or a loved one is experiencing symptoms of the disease, it’s important to speak with a doctor.
