Huntington's Disease

Overview

Huntington's disease is an inherited, progressive brain disorder caused by a genetic mutation that leads to the gradual breakdown of nerve cells in the brain. Symptoms usually appear between ages 30 and 50 and worsen over 10-30 years. The disease affects movement, cognition, and mental health. It is autosomal dominant — each child of an affected parent has a 50% chance of inheriting the gene. There is no cure, but treatments can help manage symptoms.

Symptoms

Common Symptoms

• Movement: involuntary jerking or writhing movements (chorea), muscle rigidity, slow or abnormal eye movements, impaired gait and posture
• Cognitive: difficulty planning and organizing, lack of impulse control, lack of awareness of one's own behaviors, difficulty focusing, slow processing
• Psychiatric: depression, irritability, social withdrawal, mood swings, insomnia, fatigue

Diagnosis

Diagnosis typically involves clinical evaluation, medical history, blood tests, and appropriate imaging studies. A healthcare provider will assess symptoms, order relevant laboratory work, and may refer to a specialist for confirmation.

Treatments

Treatment depends on the underlying cause and severity. Options may include medication, lifestyle modifications (diet, exercise, stress management), and ongoing monitoring. Always work with a qualified healthcare provider to develop an appropriate treatment plan.
