Understanding Huntington's Disease: Key Facts You Should Know

Huntington's Disease (HD) is a hereditary neurological disorder characterized by progressive brain cell decline. It currently has no cure and affects both mental and physical health. Typically manifesting in individuals in their 30s or 40s, symptoms can sometimes appear earlier, with juvenile Huntington's occurring before age 20, progressing rapidly. Approximately 30,000 Americans live with HD, and an estimated 200,000 are at risk of inheriting it.

Understanding Huntington's Disease

Causes

Huntington's Disease is genetic, caused by a mutation in the HTT gene that produces the huntingtin protein. The mutation results in abnormal, toxic fragments that accumulate in neurons, impairing their function.

Stages of the Disease

Early Stage: Symptoms such as involuntary movements, reasoning difficulties, and depression begin to appear and can be managed with medication, though the disease will progress.

Middle Stage: Motor control deteriorates visibly; therapies for movement, speech, and reasoning become necessary.

Late Stage: Patients become fully dependent, unable to walk or speak; choking becomes a serious concern.

Symptoms & Diagnosis

The symptoms resemble other neurological conditions and typically develop over 15-20 years. Early signs include mood swings, personality changes, memory loss, irritability, involuntary movements, and restlessness.

Testing: Diagnosis involves neurological and psychological assessments, brain scans, and definitive genetic testing with informed consent. Genetic counseling is recommended prior to testing.

Treatment Options

No cure for HD exists yet. Medications can help alleviate symptoms but may have adverse effects. Supportive therapies are vital for managing the disease progression.
