MCQ IN MEDICINE

Detailed explanation-1: -Therefore, cerebrovascular lesions of the cerebellum or its pathways can cause diverse movement disorders. These lesions typically result in the deterioration of coordination (ataxia, asynergia), misjudgment of distance (dysmetria), and intention tremors [2].

Detailed explanation-2: -An intention, rubral, cerebellar, or course tremor is defined as a rhythmic, oscillatory, and high amplitude tremor during a directed and purposeful motor movement, worsening before reaching the target.

Detailed explanation-3: -According to this hypothesis, clumsiness in cerebellar patients and dysmetria are due to a malfunction in the predictive feedforward control and/or to a disorder in the accurate appraisal of the consequences of motor commands.

Detailed explanation-4: -Tremor Patients Have Excessive Brain Activity in the Cerebellum. A new study suggests that patients with essential tremor have unusual brain waves in the cerebellum that cause the tremors (the same brain waves in mice produce tremor).
