Background:

Huntington's disease is an autosomal dominant inherited neurodegenerative disorder.
It is characterized by choreiform movements and progressive dementia.
Controversy exists regarding suicide risk, but literature suggests an increased risk, especially early in the disease.

Observation:

A case of homicide-suicide involving a father and son is presented.
The father had advanced Huntington's disease and was the homicide victim.
The son, who committed suicide, had a history of depression but no diagnosed Huntington's disease.

Findings:

The case underscores the psychiatric implications of Huntington's disease, including potential suicide risk.
Gross, histologic, and molecular genetic features of Huntington's disease are described.

Accurate diagnosis of Huntington's disease at autopsy can significantly impact surviving family members.
Understanding the psychiatric risks associated with Huntington's disease is vital for patient care and family support.
This case highlights the complex interplay between neurodegeneration, psychiatric conditions, and familial tragedy.
