Question

Quizplus · Accepted Answer

Huntington's disease (HD) is a genetic disorder that affects the brain and causes progressive degeneration of nerve cells, leading to symptoms such as involuntary movements (chorea), cognitive decline, and psychiatric issues. The fact that Matt's father and grandfather had similar problems suggests a hereditary pattern, which aligns with HD's autosomal dominant inheritance. The other options listed do not typically present with these symptoms or inheritance patterns.
