The World's Story is Yours to Tell

As we give great importance to heart attack, across my research i came across TIA which is known as transient ischemic attack, which is referred as the transient episode of neurological dysfunction caused by ischemia (loss of blood flow)-either focal brain, spinal cord or retinal – without acute infarction (tissue death). It is said that TIAs and strokes cause the same symptoms, such as contralateral paralysis (opposite side of body from affected brain hemisphere) or sudden weakness or numbness, and also that TIA may cause sudden dimming or loss of vision, aphasia, slurred speech and mental confusion
But unlike a stroke, the symptoms of a TIA can resolve within a few minutes or 24 hours.Brain injury may still occur in a TIA lasting only a few minutes. Having a TIA is a risk factor for eventually having a stroke or a silent stroke A silent stroke or silent cerebral infarct (SCI) differs from a TIA in that there are no immediately observable symptoms. A SCI may still cause long lasting neurological dysfunction affecting such areas as mood, personality and cognition. A SCI often occurs before or after a TIA or major stroke.

that's what i researched, and wanted to share it with you !F0000;">

I really found your piece very informative Zainab. I like the fact that you have given symptoms of the conditions that you have researched.
