According to a study conducted on March 8, 2005 published in Neurology. Which included the participation of people who suffered strokes. Warning signs of an ischemic stroke can occur up to seven days before it happens and require urgent treatment to avoid possible brain damage.
Eighty percent of strokes are ischemic. These are caused by narrowing of the large or small arteries in the brain or by clots that block blood flow to the brain.
They are often preceded by a transient ischemic attack (TIA), a ‘warning stroke’ or ‘mini stroke’. This shows symptoms similar to a stroke, generally lasts less than five minutes and does not damage the brain.
Important figures and what was discovered about the signs of a stroke
The study looked at 2,416 people who had suffered an ischemic stroke. 549 patients experienced a TIA before ischemic stroke and in most cases they occurred in the previous seven days. 17 percent occurred on the day of the stroke, 9 percent the day before, and 43 percent at some point during the seven days before the stroke.
It has been known for some time that TIAs are often a precursor to a major stroke. What has not been determined is how urgently patients should be evaluated after TIA for the most effective preventive treatment.
This study indicates that the timing of a TIA is totally critical. And that the most effective treatments should be started a few hours after suffering one to prevent a major attack.
The study included two other population-based studies (Oxford Vascular Study Y Oxfordshire Community Stroke Project). As well as two randomized trials (UK-TIA Aspirin Trial Y European Carotid Surgery Trial).
The American Academy of Neurology is the world’s largest association of neurologists and neuroscience professionals, with 36,000 members. The AAN is dedicated to promoting the highest quality patient-centered neurological care.
A neurologist is a physician with specialized training in the diagnosis, treatment, and management of disorders of the brain and nervous system such as Alzheimer’s disease, stroke, migraine, multiple sclerosis, concussion, Parkinson’s disease, and epilepsy.
