Hemiparesis meaning?

Explanation:
Hemiparesis means weakness on one side of the body. The prefix hemi- means half and paresis means weakness, so it’s a partial loss of motor function affecting one side. This commonly results from a brain lesion that disrupts the motor pathways, often causing weakness on the opposite side of the body from the damaged brain region. It’s different from hemiplegia, which is complete paralysis on one side. The other options describe symptoms that aren’t motor weakness on one side: weakness on both sides would be bilateral weakness, loss of consciousness isn’t a motor deficit, and numbness in the feet is a sensory issue.
