A member asked:

I have a lesion on the left side of my brain in the basal ganglia and i also have left leg paralysis. what could be the cause?

A doctor has provided 1 answer

Paralysis: Left basal ganglia lesion would cause right sided weakness. Left leg paralysis would be from a right sided lesion in the brain above the brain stem. A spinal cord lesion on the same side or below where the corticospinal fibers cross in the brain stem would cause left leg weakness. See you neurologist or neurosurgeon to identify the source of the left leg weakness.
