Question

Quizplus · Accepted Answer

Huntington's disease is a neurodegenerative disorder that affects nerve cells in the brain, leading to the deterioration and death of certain neurons. One of the hallmark symptoms of the disease is the presence of involuntary movements, such as twitching, tremors, and writhing, which can interfere with voluntary movement. This is known as chorea, and it is a characteristic feature of Huntington's disease. Other symptoms may include mood disturbances, cognitive impairment, and difficulty with balance and coordination. Rapid fatigue of the muscles (A), loss of both sensation and motor control in certain limbs (B), and impairment of saccadic eye movements and rapid alternating movements (D) are not typically associated with Huntington's disease.
