A TIA affecting the right anterior hemisphere of the brain is likely to affect which side of the body?

A transient ischemic attack (TIA) affecting the right anterior hemisphere of the brain would most likely impact the left side of the body. This occurs because of the brain's contralateral control of motor functions; in most individuals, the left side of the body is governed by the right hemisphere of the brain.

In cases of TIA, where blood flow to a part of the brain is temporarily disrupted, the resulting symptoms can parallel those seen in a stroke. Since the right anterior hemisphere is involved, the motor and sensory functions that control the left side of the body may be affected. This leads to possible weakness or sensory loss on the left side. Understanding this principle is crucial in diagnosing and managing conditions related to brain function and vascular health.
