Key Points about Huntington’s disease
- Definition: Huntington’s disease is a genetic, progressive neurodegenerative disorder that affects movement, cognition, and behaviour, typically presenting in mid-adulthood.
- Causes:
- Autosomal dominant inheritance of a CAG repeat expansion in the HTT gene.
- Progressive degeneration of neurons in the basal ganglia and cerebral cortex.
- Symptoms:
- Involuntary movements (chorea).
- Cognitive decline, including memory loss and impaired judgement.
- Psychiatric symptoms such as depression, irritability, or psychosis.
- Investigations:
- Genetic testing to confirm the presence of the HTT gene mutation.
- MRI or CT scans showing brain atrophy, particularly in the caudate nucleus.
- Neuropsychological testing to assess cognitive function.
- Management:
- Symptomatic treatment for movement disorders (e.g., tetrabenazine).
- Antidepressants or antipsychotics for psychiatric symptoms.
- Physical therapy and supportive care to maintain quality of life.
- Complications:
- Progressive functional decline leading to disability.
- Aspiration pneumonia due to difficulty swallowing.
- Increased risk of suicide due to psychiatric symptoms.
