Transient Neurological Attacks

Incidence and prognosis of transient neurological attacks.

CONTEXT Transient neurological attacks (TNAs) are attacks with temporary (<24 hours) neurological symptoms. These symptoms can be focal, nonfocal, or a mixture of both. The prognostic significance of TNAs with focal symptoms (better known as transient ischemic attacks [TIAs]) is well understood. Conversely, hardly anything is known about the prognostic significance of TNAs with nonfocal or mixe...

Transient 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...

Transient ischaemic attacks.

Each day, about 25 Australians experience a transient ischaemic attack of the brain or eye. These people need to be distinguished from those who suffer "funny turns" due to other causes because, as a group, they have a significant risk of stroke and other vascular events. This risk can be substantially reduced through control of vascular risk factors, use of long term antithrombotic medication ...

Neurological Evaluation and Diffusion-Weighted MRI Assessment of Patients with Transient Ischemic Attacks

Background: The risk of stroke after a transient ischemic attack (TIA) is high. Appropriately directed therapies may reduce this risk. However, sensitive means of detecting the presence of transient neuronal ischemia are lacking. Objective: To analyze the incidence of ischemic lesions detected by using diffusion-weighted MR imaging in patients suffering from transient ischemic attacks (TIA), an...
