Accepted Answer

Impaired rapid alternating movements of the hands

Answer

Question 2

A patient has ptosis, miosis, and anhidrosis on the right side of the face. Which condition does this suggest?

Accepted Answer

Right Horner's syndrome

Answer

Horner's syndrome (ptosis, miosis, anhidrosis) on the right results from disruption of the ipsilateral sympathetic pathway.
