EXTEND-IA Randomized Trial Of Intra-arterial Clot Retrieval In Ischemic Stroke

Summary
Most strokes are caused by a blocked blood vessel in the brain. Current treatments to dissolve the blockage improve recovery for many patients but often fail to unblock larger brain arteries. The EXTEND-IA trial will use advanced brain imaging to identify patients who have the most to gain if the blocked artery can be re-opened. The trial will test whether a new minimally invasive clot removal procedure performed after standard clot-dissolving treatment improves recovery after stroke.
Brain damage resulting from long-term alcohol abuse is localized to discrete regions of the brain and selectively impairs key neuropsychological functions. Alcohol misuse affects processes that control excitability in the brain, leading to the over-stimulation of brain cells. When this continues for long periods the cells are likely to die and most alcoholics misuse alcohol for most of their adult lives.

Alcohol misuse affects processes that control excitability in the brain, leading to the over-stimulation of brain cells. When this continues for long periods the cells are likely to die and most alcoholics misuse alcohol for most of their adult lives. We will study the human brain s capacity to use and respond to glutamate, its major natural excitant, in the regions that are selectively damaged by alcoholism. How these capacities are affected by heredity, and by diseases commonly associated with alcoholism such as cirrhosis of the liver, will also be explored. If we can understand how selective brain damage occurs in alcoholics we will be better able to devise new drug therapies to combat and prevent it. As well, localized brain damage is a feature of many neurological diseases, so the study will provide a general model of disease mechanisms.Read moreRead less
