G45.9: Transient cerebral ischaemic attack, unspecified

A transient cerebral ischemic attack, unspecified or commonly known as a mini-stroke, is a brief episode where the blood supply to a part of the brain is temporarily disrupted. This condition is characterized by sudden onset symptoms, which can include momentary weakness, numbness or a tingling sensation on one side of your body, difficulty in speaking or understanding speech, dizziness, loss of balance, and vision problems in one or both eyes. These symptoms typically disappear within an hour, but sometimes can last up to 24 hours. It's called "transient" because the symptoms often vanish before you get to the hospital. However, these episodes should not be ignored as they’re often an early warning sign of a potential, more serious, stroke.
