Transient Ischaemic Attacks
Transient ischaemic attacks (TIA’s) - Ischaemia (pronounced iskeemya) means lack of supply of blood (or more importantly, the oxygen the blood carries). A TIA is a `mini stroke` where the interruption to the blood supply is transient, and the resulting deficit resolves within 24 hours. This is usually due to a small blood clot blocking a blood vessel and then clearing by itself before the damage to the brain is irreversible. Like strokes themselves, these are very rare events in children, and always due to an underlying disorder rather than, as in the adult, atherosclerotic disease (see the adult section).
