[Transient ischemic attacks (TIA) from the viewpoint of the clinical neurologist]

A transient ischaemic attack (TIA) is a cerebrovascular attack the clinical symptomatology of which is restored to normal within 24 hours. Minor haemorrhages, epilepsy, hypoglycaemia, migraine and even peripheral neuropathies can be mistaken for TIA. CT examination indicates in a considerable percentage of examined subjects encephalomalacia. The term TIA should be reserved for ischaemic attacks, where after regression of the clinical symptomatology within 24 hours no structural changes are found.
