G45: Transient cerebral ischaemic attacks and related syndromes

The group of conditions referred to as Transient Cerebral Ischaemic Attacks and Related Syndromes (G45) primarily involve short-lived disruptions of blood flow to the brain. These disturbances often result from blockages in the blood vessels that supply the brain, typically linked to heart disease or blood clotting disorders. Symptoms can range from momentary weakness, numbness, or tingling in the face, arm, or leg, usually on one side of the body, to sudden confusion, trouble speaking or understanding, and loss of balance or coordination. Though brief, these signs should not be ignored as they may foretell a forthcoming, potentially life-threatening stroke. Disease progression varies, but its severity depends largely on the duration and location of blood flow disruption. Notably, these conditions do not cause permanent brain damage and the symptoms usually resolve within 24 hours.
