Neuropsychology Abstract of the Day: Suicidal Behavior and Semantic Dementia

Suicidal Behavior in Dementia: A Special Risk in Semantic Dementia.American Journal of Alzheimer's Disease and Other Dementias. 2013 Jul 1;Sabodash V, Mendez MF, Fong S, &Hsiao JJAbstractBackground: Some studies report a low suicide risk in general dementia and in Alzheimer's disease (AD).Objective:To evaluate suicidal behavior among patients with semantic dementia (SD), a disorder that impairs semantic knowledge. Methods: We reviewed the presence of active suicidal behavior and related factors among 25 patients with SD compared to 111 age-matched patients with early-onset AD. Results: In all, 5 (20%) patients with SD had suicidal behavior (2 successfully killed themselves) compared to 1 (0.9%) with AD (P

l A, Reynoso-Robles R, Mukherjee PS Abstract Exposures to fine particulate matter (PM2.5) and ozone (O3) above USEPA standards are associated with Alzheimer's disease (AD) risk. Metropolitan Mexico City (MMC) youth have life time exposures to PM2.5 and O3 above standards. We focused on MMC residents ≤30 years and reviewed 134 consecutive autopsies of subjects age 20.03 ± 6.38 y (range 11 months to 30 y), the staging of Htau and ß amyloid, the lifetime cumulative PM2.5 (CPM 2.5) and the impact of the Apolipoprotein E (APOE) 4 allele, the most prevalent genetic risk for AD. We als...

Conclusion A great deal of progress is being made in the matter of treating aging: in advocacy, in funding, in the research and development. It can never be enough, and it can never be fast enough, given the enormous cost in suffering and lost lives. The longevity industry is really only just getting started in the grand scheme of things: it looks vast to those of us who followed the slow, halting progress in aging research that was the state of things a decade or two ago. But it is still tiny compared to the rest of the medical industry, and it remains the case that there is a great deal of work yet to be done at all...

I tried to kill my father for years. To be fair, I was following his wishes. He’d made it clear that when he no longer recognized me, when he could no longer talk, when the nurses started treating him like a toddler, he didn’t want to live any longer. My father was 58 years old when he was diagnosed with Alzheimer’s disease. He took the diagnosis with the self-deprecating humor he’d spent a lifetime cultivating, constantly cracking jokes about how he would one day turn into a zombie, a walking corpse. We had a good 10 years with him after the diagnosis. Eventually, his jokes came true. Seven years ...

Alzheimer's disease and other progressive neurodegenerative dementias are growing as the population ages. Managing dementia is challenging from economic, societal, and ethical perspectives. One significant ethical issue concerns people who want to avoid living with advanced dementia. Current strategies (suicide and traditional advance directives) are suboptimal or inadequate. Stopping eating and  drinking by advance directive (SED by AD) is a better potential solution.

CONCLUSIONS: Advance and concurrent request EAS cases differ in age, duration of illness, and past experience. Advance request EAS cases were complicated by ambiguous directives, patients being unaware of the EAS procedure, and physicians' difficulty assessing "unbearable suffering." Notably, some concurrent request patients were quite impaired yet deemed competent by appeals to previous statements. PMID: 31537470 [PubMed - as supplied by publisher]

This study sought to investigate what could be learned from how these men have fared. The men were born in 1925-1928 and similar health-related data from questionnaires, physical examination, and blood samples are available for all surveys. Survival curves over various variable strata were applied to evaluate the impact of individual risk factors and combinations of risk factors on all-cause deaths. At the end of 2018, 118 (16.0%) of the men had reached 90 years of age. Smoking in 1974 was the strongest single risk factor associated with survival, with observed percentages of men reaching 90 years being 26.3, 25.7, ...

Conclusion: The clinical approach to a PAD request should consider the legal framework and the decision-making capacity, assess memory deficit awareness and the perception of suffering, and evaluate mental competency when considered pertinent.Dement Geriatr Cogn Disord Extra 2019;9:217 –226

In this study, we found that cofilin competes with tau for direct microtubule binding in vitro, in cells, and in vivo, which inhibits tau-induced microtubule assembly. Genetic reduction of cofilin mitigates tauopathy and synaptic defects in Tau-P301S mice and movement deficits in tau transgenic C. elegans. The pathogenic effects of cofilin are selectively mediated by activated cofilin, as active but not inactive cofilin selectively interacts with tubulin, destabilizes microtubules, and promotes tauopathy. These results therefore indicate that activated cofilin plays an essential intermediary role in neurotoxic signaling th...
