Spouses of dementia sufferers have a 6-fold increased risk of dementia onset

05.05.2010
Husbands appear at higher risk than wives

Older married adults whose spouse has dementia are at significantly higher risk for developing dementia themselves, compared to similar older married adults whose spouse never develops dementia. This is the key finding of a study published today in the Journal of the American Geriatrics Society.

Informal dementia caregiving for a spouse is a natural marital obligation, and spousal caregivers often report positive feelings toward caregiving, yet it is difficult, requiring time, energy and usually physical exertion. Dementia caregivers have been shown to provide more assistance, and to report more personal sacrifices and stress, than those who care for physically-impaired elderly without dementia. While there are many published studies showing that dementia caregivers are at higher risk for health problems and depression, none have examined risk for dementia in the caregiver.

2,442 subjects (1,221 married couples) aged 65 and older from Northern Utah, USA, without dementia at onset were studied for up to 12 years to monitor for onset of dementia in husbands, wives or both. During this time, 125 cases of dementia only in the husband were diagnosed, 70 only in the wife, and 30 where both spouses were diagnosed (60 people).

The researchers, led by Dr. Maria Norton of Utah State University, USA, adjusted for socioeconomic status, a significant predictor of many health-related outcomes including dementia to control for shared environmental exposures that might influence risk for dementia in both spouses.

The results showed that incident dementia was significantly associated with older age, and having a spouse with dementia. Participants with a spouse who developed dementia were at a six times increased risk of developing dementia, net of the effect of age, gender, APOE genotype, and socioeconomic status, with higher risk in men (11.9) than women (3.7).

"Future studies are needed to determine how much of this association is due to caregiver stress compared to a shared environment," said Norton. "On the positive side, the majority of these individuals, with spouses who develop dementia, did not themselves develop dementia, therefore more research is needed to explore which factors distinguish those who are more vulnerable."

"Given the significant public health concern of Alzheimer's disease and other dementias, and the upcoming shift in population age composition, continued research into the causes of dementia is urgent," concluded Norton.

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
