STROKE, dementia or Parkinson’s: 1 woman on 2 and 1, man on 3 at-risk

AVC, démence ou Parkinson: 1 femme sur 2 et 1 homme sur 3 à risque

PARIS — One in two women and one in three men are at risk of developing a neurological disease such as STROKE, dementia or Parkinson’s over the course of his life, writes a Dutch study published Tuesday in the Journal of Neurology Neurosurgery and Psychiatry.

The study is based on the observation of 12.102 people over the age of 45 years, from 1996 until their death or until January 1, 2016.

On 5.291 deaths that have occurred during the 26 years under review, 1.489 had dementia, mostly Alzheimer’s (80%) some 1,285 a cerebral vascular accident (STROKE), and 263 a of Parkinson’s disease.

Not surprisingly, the risk increases with age, but it also differs significantly according to the sex: one in two women (48%) 45 risk on the basis of this epidemiologic study to develop one of three diseases in the course of his life against a man on only three of them (36%).

Women have a far higher risk of developing dementia than men, while men are at risk of STROKE at an earlier age than women.

A woman has twice the risk of a man developing both dementia and STROKE.

The study has its limitations, note the authors, particularly because they focus on a european population whose life expectancy is higher: 83,5 years for women in the netherlands and 81.7 years for men in the netherlands.

The researchers stress that the risk of dying from one of these neurological diseases remains poorly appreciated, compared to the risk posed by breast cancer (one woman out of 8) or cardiovascular disease (4), which hinders prevention strategies.

However, the three diseases share the same risk factors, and weighing more and more in public expenditure with the aging of the population, do they.

People diagnosed with any of the three diseases within the framework of follow-up between 1990 and 2016 have more high blood pressure, heart rhythm disorder (atrial fibrillation), cholesterol, and type 2 diabetes (the most common), the study finds.

Prevention, which would delay a few years the onset of the neurological disease, may reduce the risk of 20% to 50%, note the researchers.

These results argue in favour of preventive measures energetic “to reduce the burden of neurological diseases in the elderly population”, conclude the researchers.
