Tremors and a shuffling gait are typical signs of which condition?

• A. Alzheimer's
• B. Parkinson's
• C. COPD
• D. Diabetes

Answer: (B)

Tremors at rest and a shuffling, small-step gait are classic signs of a movement disorder caused by dopamine loss in the brain's basal ganglia. In Parkinson's disease, loss of dopamine-producing neurons in the substantia nigra leads to impaired initiation and control of movement, producing a resting tremor, slowed movement (bradykinesia), rigidity, and a characteristic shuffly gait with reduced arm swing. The gait often starts as small steps, with difficulty starting to walk and a tendency to shuffle forward.

Other conditions don’t typically present with this exact combination as a defining feature. Alzheimer’s disease mainly affects memory and cognition, COPD involves breathing difficulties, and diabetes affects blood sugar and nerves but does not produce the classic resting tremor together with a shuffling gait in the early stages.
