Older adults whose spouse has Alzheimer's or another form dementia face an increased risk of dementia themselves, a new study finds. According to the study, unpaid dementia caregiving for a spouse is a natural marital obligation, and although spousal caregivers may report positive feelings toward caring for their loved one, it is also associated with considerable physical and mental demands, as well as significant stress, as they observe the deterioration of their life partner. However, the investigators note that the effects of this stress, "which have been most studied in the context of caregiving, may increase the risk of negative cognitive outcomes in the spouse, although this has been relatively unexplored."
It included 2,442 people (1,221 married couples), aged 65 and older, in Utah who were dementia-free at the start of the study. During 12 years of follow-up, 125 husbands and 70 wives developed dementia, and both the husband and wife developed dementia in 30 couples. After adjusting for a number of factors, the researchers found that people with a spouse who developed dementia were six times more likely to develop dementia themselves than people whose spouses never had dementia. Men had a higher risk than women. Older age was also significantly associated with dementia risk. Read more: healthscout.com

Bisphenol A exposure could affect male hormone levels

The paper, published in the journal Environmental Science and Technology, said BPA was detected in 89 per cent of urine samples with a media range of 1.3 ng/mL. It also found that men with higher urine BPA concentrations had higher blood levels of follicle-stimulating hormone (FSH) and lower levels of inhibin B. Raised FSH and depressed inhibin B have been associated with poorer sperm quality in humans.   Read more: foodproductiondaily.com
