Which combination of symptoms is commonly seen in Spinocerebellar Ataxias?

• A. Ataxia plus neuropathy
• B. Isolated tremor
• C. Pure motor paralysis
• D. Optic neuritis

Answer: (A)

Spinocerebellar ataxias commonly involve both the cerebellum and peripheral nerves, so patients typically show coordination problems (ataxia) along with signs of neuropathy such as sensory loss or distal weakness. This combination reflects the dual-site degeneration that characterizes many SCAs. Other options don’t fit as well: isolated tremor is more typical of other tremor syndromes, pure motor paralysis suggests a different motor-neuron or corticospinal process, and optic neuritis points to inflammatory conditions like multiple sclerosis rather than spinocerebellar degeneration. Thus, ataxia plus neuropathy is the most representative presentation.
