Stroke or CVA (Cerebro Vascular Accident) has different categories, TCA (not serious type), Ischemic type (can recover after the stroke) and hemorrhagic type (poor prognosis and can lead to coma or death). A stroke causes neurological damage either temporary or permanent cause by loss of blood supply to the brain leading the person to change his/her attitude and personality plus the irritability the client experience. If your the significant others, be patient to the client because we can consider their changes in attitude as "complication" to the illness he/she suffers.
