What are the characteristics of neocerebellar syndrome?

Correct answer is B). Neocerebellar syndrome is characterized by ataxia (uncoordinated movements), dysmetria (difficulty judging distances), and disturbances in the precision of voluntary movements. It primarily involves dysfunction in the neocerebellum, one of the functional subdivisions of the cerebellum, which plays a role in motor coordination and motor learning. A) Incorrect. Hypotonia and flaccidity in the limbs are not typical features of neocerebellar syndrome but may be associated with other neurological conditions. C) Incorrect. Involuntary, rapid, and non-repetitive movements are characteristic of chorea, which is distinct from neocerebellar syndrome. D) Incorrect. A deficiency of the neurotransmitter dopamine is more relevant to conditions like Parkinson's disease and is not the primary feature of neocerebellar syndrome.
