Stroke is often perceived as an unpredictable event. In this case, the concrete symptoms prematurely signal cerebral infarction in many cases.
In addition to neurological disorders such as visual disturbances and a temporary feeling of numbness, memory disorders may be the precursors of a stroke. This is what Chinese neurologists at Chiayi Chang Gung Memorial Hospital have discovered in a meta-study.
It was based on data from 18 studies performed on a total of 121,879 patients. Their findings were published in the Canadian Medical Association Journal.
Mental minimum value as a parameter
Memory problems – reported by physicians as cognitive limits – were measured with the so-called mini-mental state test, which is also used to diagnose dementia and Alzheimer's. The team around dr. Meng Lee then established a mini-mental status score of 25 points. On this basis, the patient data available were evaluated.
Stroke risk increased by 40%
Factors such as increased age, hypertension, diabetes and obesity have been included in the risk assessment. Taking these factors into account, the stroke rate was 40% higher in patients with cognitive impairment or dementia compared to those without memory problems.
The danger of an ischemic attack is even higher
The risk of having a transient ischemic attack (TIA) increases by 65% in patients with mental impairment. A TIA is a transient circulatory disorder in the brain, a type of "mini-stroke" that is often followed by a real stroke after a while.
About the reasons why memory problems obviously have one race the researchers are not clear enough yet. However, they suspect that those affected already have brain damage caused by a heart attack or cerebral circulatory disorders.
A stroke can be prevented
To minimize the risk of stroke, everyone can act on their own. Many risk factors can be affected. These include hypertension, smoking, stomach fat, unhealthy diet and lack of exercise. They represent 80 percent of all hits. This demonstrated the analysis of several thousand stroke patients in North America.
Hypertension is the most dangerous
The doctors of Martin O & # 39; Donnel of the Canadian McMaster University have compared the data of 3000 patients with stroke with those of 3,000 healthy people. Hypertension was the most important risk factor: it increases the risk up to more than 2.5 times. Hypertension plays a role in every third stroke. Smoking is almost dangerous, doubling the risk of stroke.
A healthy lifestyle, particularly a balanced and low-fat diet, lots of exercise and a refrain from smoking could significantly contribute to minimizing the individual risk of stroke.
