“Body clock” may be the risk of dementia in women

An old woman sleep / wake stages aktiviti fizikal orbit and may affect the risk of dementia he built, according to a new investigation.

He found bahawa risk of dementia or “mild cognitive kerosakan” (a country which sometimes precede dementia) is higher among older women with low circadian rhythm is less active and more active in fizikal at the end of life, compared with those who havecircadian rhythm firm and more active on the previous day.

“We’ve recognized for some time bahawa circadian rhythm, what people always call” biological clock “may give the impression to our brains and our keupayaan to function normally,” said lead author, Greg Tranah, an investigator at the California Pacific Medical Center Institute investigation, the institute said in a news reality.

“What our decisions bahawa reserve intervention is the future, as aktiviti fizikal increases or the use of intervention to influence the circadian behavior of light exposure, may help to influence cognitive [mental] older woman’s decision,” he said.

Tranah and movement-movement makes data analysis rather than an adviser almost 1300 women over 75 who were followed for five years. At the end of that period, 15 women had been awakened peratus than dementia and 24 peratus kerosakan have some form of mild cognitive impairment (MCI).

Women with a weak circadian rhythm of the lower stage aktiviti fizikal or more active end of life is 80 peratus more likely to wake dementia or MCI compared with a robust circadian rhythm early on this day, the troops encountered.

“To our knowledge, this is the first study to show a strong relationship between circadian rhythms aktiviti and onward development of dementia or MCI,” said Tranah. The discovery of the unity of our other features indicate, however, and can not prove cause and effect.

“The reason this is so obvious,” he said. “Changes in circadian behavior may directly affect the onset of dementia or MCI, or decreased aktiviti may result, signs warn if you will, bahawa applicable changes in the brain. Know exactly what is why he should help us to wake therapy to suspend or slow down progress of brain matter in the elderly. “
