Severe StressThe severe stress is associated with the development of ischemic stroke, a study from Gothenburg University in Sweden published in the journal BioMed Central Medicine. The researchers caution that has not yet been proven that stress is an independent risk factor for stroke even affect the need for studies to clarify its role.

Explains Katarina Jood, director of research, “we found an independent association between self-perceived psychological stress and ischemic stroke. A new discovery was that this association differed between subtypes of ischemic stroke.

The researchers asked 566 patients of ischemic stroke and 593 controls to appraise their levels of stress in a six-point scale from ‘never stressful’ to ‘constantly stressed in the past 5 years. ” Patients were divided between groups of stressed and unstressed.

When the researchers compared the incidence of stroke and type the results showed a strong correlation between prolonged stress and the large blood vessel disease, small vessel disease and cryptogenic stroke.

“Our results should be interpreted with caution because the case-control design could lead to an overestimation of stress as a risk factor for stroke. However, the study contributes to the indications that the association between stress and stroke could differ between different subtypes of stroke and points to the need for prospective studies on the relationship between stress and stroke “according to the researcher.

Stress may be related to behaviors associated with increased susceptibility to stroke, including smoking, physical inactivity and socioeconomic status. Moreover, frequent or persistent activation of the sympathetic nervous system, besides the hypothalamus pituitary and adrenal glands may also lead to hypertension and metabolic disorders that lead to strokes.
Strokes are currently one of the leading causes of death worldwide and cause about 9.7 percent of deaths according to the World Health Organization, so knowing the causes is a vital goal.
