"Good news" for those with genetic risk for Alzheimer's

Regardless of how much genetic risk someone has, a good diet, adequate exercise, limiting alcohol and not smoking made dementia less likely

There hasn’t been much good news about Alzheimer’s lately, between the March announcement by Biogen and Esai that a promising trial of a potential drug treatment failed, and the July decision by Novartis and Amgen to stop their study of another class of therapies for the neurodegenerative disease. But in a pair of studies presented at the annual Alzheimer’s Association International Conference on July 14, researchers reported encouraging results from studies of non-drug approaches. In one, scientists led by Dr. Klodian Dhana at Rush University Medical Center in Chicago followed nearly 2,500 people for alm...

As one of the five major senses, you could argue that our sense of smell is the least important. Sight, hearing, touch, and taste may poll better than smell, but try telling that to someone who has lost their sense of smell entirely. The truth is that loss of the ability to smell comes with a significant cost, because olfaction serves several purposes that affect quality of life and even safety, including stimulation of appetite enhancement of the sense of taste alerting you to which foods should not be eaten (if they’re rotting, for example) warning you of danger (as with smoke warning of fire). Loss of smell can ...

Right now the world is experiencing an epidemic that is projected to get much, much worse. It’s an epidemic of dementia, affecting 50 million people and millions more of their caregivers — staggering numbers that are projected to triple by 2050. The dementia crisis is such a massive worldwide issue that the World Health Organization (WHO) announced a strategic public health action plan, including compiling an organized database of quality dementia research and creating guidelines for the prevention of dementia. The guidelines have just been published, a 96-page document that is summarized here, as well as in th...

Conclusions: Protein-drug interaction analysis revealed PDE9A has interaction with drugs caffeine, γ-glutamyl glycine, and 3-isobutyl-1-methyl-7H-xanthine. Thus, we identified novel putative links between pathological processes in IS and AD at transcripts levels, and identified possible mechanistic and gene expression links between IS and AD.

It is quite easy to find correlations between the many varied aspects of aging. People age at different rates, largely due to differences in lifestyle choices: exercise, calorie intake, smoking, and so forth. Genetics are less of an influence. While there is tremendous interest in the genetics of aging, I have to think that this is something of a case of a hammer in search of a nail. This is an era of genetic technologies and genetic data, in which the cost of the tools has fallen so low and the scope of the capabilities has expanded so greatly that everyone is tempted to use it in every possible circumstance. Yet outside ...

The objective of this study was to evaluate mood, lifestyle and the presence of cardiovascular risk factors in older women caregivers of patients with Alzheimer´s disease (AD) dementia compared to non-caregivers living in the neighborhood. METHODS: Paired case-control (1:1). Volunteers responded to a questionnaire with information about physical and leisure activities, smoking, alcohol use, and daily hours of care. Blood pressure (BP) was measured on 5 days with the Home Blood Pressure Monitoring (HBPM) system, and mood was assessed with the Geriatric Depression Scale (GDS) and Mini International Neuropsychiatri...

This study shows that mRNA levels of the aging related lamin A splice variant progerin, associated with premature aging in HGPS, were significantly upregulated in subjects with BMI ≥ 25 kg/m2. Moreover, our data revealed a significantly positive correlation of BMI with progerin mRNA. These data provide to our knowledge for the first-time evidence for a possible involvement of progerin in previously observed accelerated aging of overweight and obese individuals potentially limiting their longevity. Our results also showed that progerin mRNA was positively correlated with C-reactive protein (CRP). This might suggest an as...
