The role of traditional risk factors in the pathophysiology of stroke (IS) has been established and is well know. It has recently been shown that 10 risk factors are associated with 90% of the risk of stroke. Traditional risk factors have a role to play in the pathophysiology
of stroke (Ischemic Stroke). This is now well established . Recent studies have shown that 10 risk factors are associated with 90% of the risk of stroke . Inspite of this, it is impossible to predict when a stroke will occur, even in people with a high-risk profile . The patterned
occurrence with a morning peak of Ischemic Stroke onset strongly suggest that the disease does not occur randomly . Further, it has
been hypothesized that vascular events could be precipitated by acute factors, called triggers, which may directly lead to its onset. Average negative emotion scores were calculated for the nine negative items in the five level PANAS for each patient during the hazard and control periods. The methodology was similar as in study conducted previously on MI . Patients were asked to recall any sudden change in posture during the day preceding stroke onset. For
each reported sudden change in posture, the exact time and reason were specified. The present study examined a possible association between exposure to potential triggers during a defined hazard period and triggering of the acute onset of stroke. Almost 66% of patients reported exposure to at least one potential trigger. In a previous study, a sharp rise in
incidence of AMI and sudden death in Israel was noted during the first days of the Gulf Warcompared to control periods and increased risk of cardiovascular events was reported during earthquakes.
