Stroke DictionaryA-E | F-J | K-O | P-S | T-Ztemporal lobe: Controls memory, personality, and language. The temporal lobe also allows us to distinguish smells and sounds. thrombus: Or blood clot, which can cause an ischemic stroke. transient ischemic attack (TIA): Or "mini stroke," symptoms last less than 24 hours, and occur when circulation to an area of the brain is temporarily restricted. On average, in fact, TIA symptoms last only two to 30 minutes and no permanent brain damage occurs. TIAs do, however, suggest blood vessel disease and a third of all people who experience TIA will go on to suffer a stroke. vasospasm: Blood vessels surrounding the ruptured blood vessels constrict, restricting blood flow to parts of the brain and causing further brain tissue damage. voice hoarseness: May result from muscle paralysis or other effects of stroke that affect the vocal cords. Wallenberg’s syndrome: A neurological condition caused by a stroke in the vertebral or posterior inferior cerebellar artery of the brain stem. Symptoms include difficulties with swallowing, hoarseness, dizziness, nausea and vomiting, rapid involuntary movements of the eyes (nystagmus), and problems with balance and gait coordination.
