Question: 1 / 1180

Which condition is characterized by the striatum's inability to prevent parts of the body from moving intentionally?

Parkinson's Disease

Huntington's Disease

Huntington's Disease is a genetic disorder that affects the brain, specifically the striatum which is involved in regulating voluntary movement. The striatum's role is to inhibit inappropriate or unintended movements, so in Huntington's Disease, the striatum is unable to do so effectively. Parkinson's Disease, on the other hand, is characterized by reduced dopamine levels in the brain and affects motor control. Epilepsy is a neurological disorder that causes seizures, not necessarily related to intentional movement. Amyotrophic Lateral Sclerosis (ALS) is also known as Lou Gehrig's Disease and affects the nerve cells responsible for controlling voluntary muscles, leading to difficulty with intentional movement. Therefore, Huntington's Disease is the correct answer as it specifically affects the striatum and is associated with issues in controlling intentional movement.
