What is a symptom of hemiplegia?

Hemiplegia is characterized by paralysis affecting one side of the body, which can be either complete or partial. This condition often results from damage to the brain, such as from a stroke, that affects motor control pathways. The defining feature of hemiplegia is the unilateral loss of movement, where one side experiences reduced or absent muscle function.

The other options relate to different neurological or sensory issues that do not specifically define hemiplegia. For instance, the inability to recognize objects pertains to agnosia, generally affecting perception and cognition rather than motor capabilities. No sensation in both arms refers to a bilateral sensory deficit, which is not consistent with hemiplegia's characteristic of unilateral paralysis. Difficulty in speech production relates to aphasia or dysarthria, conditions that affect language or speech but do not directly involve paralysis of the body. Hence, the selection highlighting paralysis on one side accurately reflects the primary symptom associated with hemiplegia.
