Huntington's disease is characterized by which of the following?

Huntington's disease is primarily characterized by chorea movements, which are involuntary, irregular, and unintentional movements that can appear as sudden, jerky motions. This hallmark symptom results from neurodegeneration, particularly in areas of the brain that control movement coordination. As the disease progresses, individuals often display a range of additional symptoms, including cognitive decline and psychiatric issues, but the defining feature in the context of movement disorders is the peculiar dance-like movements known as chorea.

While tremors, seizures, and memory loss can occur in various neurological conditions, they are not specific markers of Huntington's disease. Tremors, which involve rhythmic shaking, are more commonly associated with conditions like Parkinson's disease. Seizures can manifest in many different disorders but are not a primary characteristic of Huntington's. Memory loss does occur in this condition due to the cognitive decline that follows, but it tends to be part of a broader spectrum of symptoms rather than a defining feature, making chorea the most distinctive symptom associated with Huntington's disease.
