Having purpose in life 'could reduce stroke risk'

My purpose is to reduce the stroke damage worldwide by disseminating information that our medical staff should already know but don't.

A study of over-50s found that those who had defined goals for the future were at a much lower risk of suffering a clot on the brain than people with few objectives.

It remains unclear whether setting aims later in life makes people more likely to keep up a healthy lifestyle, or whether thinking positively about one's life somehow protects against a stroke, researchers said.

About 200 people in the UK die from a stroke every day, and the NHS spends £2.3 billion a year treating the 100,000 people who suffer from one every year.

A stroke happens when a blood clot prevents oxygen from reaching the brain, causing brain cells to break down and often robbing patients of certain abilities such as speech or the movement of their limbs.

Researchers from the University of Michigan studied 6,739 men and women, all of whom were aged over 50, and used questionnaires to assess to what extent each person had a purpose in life.

People with high scores for "directedness", who felt that their life had meaning and had clear goals for the future, were 22 per cent less likely to have a stroke than those who lacked a sense of purpose.
Writing in the Journal of Psychosomatic Research, the researchers concluded: "'Among older adults, greater purpose in life is linked with a lower risk of stroke."
