Health:LACUNAR INFARCT-UNNOTICED STROKE

Routinely   a person is diagnosed to be having a stroke when there is sudden and dramatic onset of paralysis of one or more parts of the body with or without loss of consciousness. This usually occurs due to sudden cessation of blood supply to part of the brain, rendering affected tissue necrotic and non functional. The underlying cause is commonly a blood clot blocking the lumen of one or more of the blood vessels supplying the brain. It can also be due to minor or major bleeding in the blood vessels.  The net result of either   of these mechanisms is death of part of brain tissue.
