| transient global amnesia | A memory disorder seen in middle aged and elderly persons characterised by an episode of amnesia and bewilderment which persists for several hours; during the episode the patient has a memory defect for present and recent past events, but is fully alert, oriented, capable of high-level intellectual activity, and has a normal neurological examination.

| transient ischaemic attack | A transient ischaemic attack is a temporary paralysis, numbness, speech difficulty or other neurologic symptoms that start suddenly and recovers within 24 hours (typically resolve over several hours). See: neurologic symptoms, stroke. Acronym: TIA (26 Mar 1998) |
| transient ischemic attack | A sudden focal loss of neurological function with complete recovery usually within 24 hours; caused by a brief period of inadequate perfusion in a portion of the territory of the carotid or vertebral basilar arteries. (05 Mar 2000) |
| transient retinopathy | Transient traumatic retinal angiopathy due to a sudden rise in venous pressure, as in compression of the body from seat belt injury; ocular fundi show large white patches associated with the retinal veins about the disk or macula, haemorrhages, and retinal oedema; thought to be due to fat embolism from bone marrow.
