Half of women will develop dementia, Parkinson's disease or have a stroke in their lifetime, new research suggests.

Approximately a third of men aged 45 are also likely to go on to be diagnosed with one of the conditions, according to a study of more than 12,000 people.

The researchers, from the University Medical Centre Rotterdam, in the Netherlands, said preventative measures could "substantially" reduce the burden.

The findings have been published in the 'Journal of Neurology, Neurosurgery, and Psychiatry'.

The health of 12,102 people was monitored between 1990 and 2016, with all participants initially under the age of 45.


During this period 1,489 were diagnosed with dementia and 263 with parkinsonism, while 1,285 had a stroke.

The overall risk of a 45-year-old later developing one of the three conditions was 48pc for women and 36pc for men, the researchers said.

Dementia was of greatest concern for women, who at 45 years old had a 25.9pc risk of going on to develop the condition, compared with 13.7pc for men.

Those diagnosed with one of the three conditions were found to have a higher prevalence of high blood pressure, abnormal heart rhythm, high cholesterol and Type 2 diabetes at the start of the monitoring period.

They estimate that if onset of dementia, parkinsonism and stroke was delayed by one to three years, the remaining risk of developing the conditions could be cut by 20pc among 45 year olds and more than 50pc in those older than 85 years of age.
