Cerebrovascular adaptations to cocaine-induced transient ischemic attacks in the rodent brain.
Occurrence of transient ischemic attacks (TIA) and cerebral strokes is a recognized risk associated with cocaine abuse. Here, we use a rodent model along with optical imaging to study cocaine-induced TIA and the associated dynamic changes in cerebral blood flow velocity (CBFv) and cerebrovasculature. We show that chronic cocaine exposure in mice resulted in marked cortical hypoperfusion, in sig...
متن کاملProgress in Cerebrovascular Disease Treatment of Transient Ischemic Attacks
Transient ischemic attacks are the most important warning symptoms of impending stroke. They occur in up to one-half of all patients who develop stroke but, unfortunately, less than half of the patients who have them seek help from their physicians before stroke occurs. Physicians should regularly question patients about the possibility of such symptoms and patients with them should seek prompt...
متن کاملBrain circulation in cerebral transient ischemic attacks.
Cranial blood flow, mean cranial transit time and cranial blood volume were measured by the intravenous RISA technique in 10 patients with cerebral transient ischemic attacks (TIA) at the various time intervals from the onset of last attack. Cranial blood flow was subnormal in 5 out of 11 determinations and mean transit time trended to be prolonged in the diseased hemisphere in cases suggestive...
متن کاملAn epidemiologic study of cerebrovascular disease in western Japan: with special reference to transient ischemic attacks.
The prevalence and incidence ratios of cerebrovascular disease, with special reference to transient ischemic attack (TIA), were studied in the towns of Daisen and Ama in western Japan. There have been no previous reports on this subject in Japan. The prevalence ratios of TIA were estimated to be 4.4 in Daisen and 2.0 in Ama per 1,000 people over 40 years old. The ratio of carotid arterial syste...
متن کاملTransient cerebral ischemic attacks.
“Stroke” is defined as rapid onset of focal neurological deficit, resulting from diseases of the cerebral vasculature and its contents. The term “transient ischemic attacks” (TIA) implies warning symptoms of stroke usually lasting upto 30 minutes to one hour, and complete recovery within 24 hours. Second TIA often causes more damage than the first. Without proper treatment one out of ten subjec...
