Overview

Symptoms vary widely from person to person depending on the area of the brain involved. The most frequent symptoms include temporary loss of vision (typically amaurosis fugax), difficulty speaking (dysarthria), weakness on one side of the body (hemiparesis), numbness usually on one side of the body, and loss of consciousness. If there are neurological symptoms persisting for more than 24 hours, it is classified as a cerebrovascular accident (stroke).

History and Symptoms

Symptoms begin suddenly, last only a short time (from a few minutes to 1 - 2 hours), then disappear completely. They may occur again at a later time. Symptoms usually occur on the same side of the body if more than one body part is involved.

A TIA is different from a stroke. However, the symptoms of TIA are the same as the symptoms of a stroke and include the sudden development of:

• Muscle weakness of the face, arm, or leg (usually only on one side of the body)
• Numbness or tingling on one side of the body
• Trouble speaking or understanding others who are speaking
• Problems with eyesight (double vision, loss of all or part of vision)
• Changes in sensation, involving touch, pain, temperature, pressure, hearing, and taste
• Change in alertness (sleepiness, less responsive, unconscious, or coma)
• Personality, mood, or emotional changes
• Confusion or loss of memory
• Difficulty swallowing
• Difficulty writing or reading
• Lack of coordination and balance, clumsiness, or trouble walking
• Abnormal sensation of movement (vertigo) or dizziness
• Lack of control over the bladder or bowels
• Inability to recognize or identify sensory stimuli (agnosia)
