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.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
