Sleep disturbances may increase risk Alzheimer's disease risk in Hispanic people

In the short-term, sleep disorders cause an inconvenience. But over time, researchers say, these disorders can increase risk for Alzheimer's disease, with greatest risk coming for Hispanic people.

(RMIT University) New research shows damage in the brain starts in the same place and spreads in the same way in sleep apnea, as in Alzheimer's disease. The study is the first to find Alzheimer's-like amyloid plaques in the brains of people with clinically-verified obstructive sleep apnea, a condition that affects more than 936 million people worldwide.

This study included a carefully selected cohort of females with mild-moderate AD confirmed by biological evaluation (n = 29). The individuals were submitted to one-night PSG to diagnose OSA (apnea-hypopnea index ≥ 15/h) and the blood was collected in the following morning. The plasma miRNA profile was evaluated using RT-qPCR. The patients had a mean (SD) age of 75.8 (5.99) years old with a body mass index o f 28.6 (3.83) kg m−2. We observed a subset of 15 miRNAs differentially expressed between OSA and non-OSA patients, of which 10 were significantly correlated with the severity of OSA. B...

This article gives a summary of the main results of MEL therapy in some neurological diseases and insomnia approved by this consensus group. Exogenous MEL, which crosses the blood-brain barrier, has been used as a treatment in its two available forms: an immediate release form that principally shows a chronobiotic action and a long release form that mimics the physiological MEL secretion rhythm and is used to replace reduced physiological secretion. MEL secretion decreases frequently with age, mostly in elderly insomniacs and dementia patients. Results of level A studies show that MEL therapy, used as an add-on treatment, ...

Sleep inhibition induced by amyloid-β oligomers is mediated by the cellular prion protein. J Sleep Res. 2020 Sep 09;:e13187 Authors: Del Gallo F, Bianchi S, Bertani I, Messa M, Colombo L, Balducci C, Salmona M, Imeri L, Chiesa R Abstract Sleep is severely impaired in patients with Alzheimer's disease. Amyloid-β deposition in the brain of Alzheimer's disease patients is a key event in its pathogenesis and is associated with disrupted sleep, even before the appearance of cognitive decline. Because soluble amyloid-β oligomers are the key mediators of synaptic and cognitive dysfunction in A...

BackgroundIn March 2020, the World Health Organization declared a global pandemic due to the novel coronavirus SARS-CoV-2 and several governments planned a national quarantine in order to control the virus spread. Acute psychological effects of quarantine in frail elderly subjects with special needs, such as patients with dementia, have been poorly investigated. The aim of this study was to assess modifications of neuropsychiatric symptoms during quarantine in patients with dementia and their caregivers.MethodsThis is a sub-study of a multicenter nation-wide survey. A structured telephone interview was delivered to family ...

CONCLUSION: The NPI is a useful tool to detect NPS in those with MCI-LB. The MCI-LB group had a higher prevalence of core features (visual hallucinations and RBD) and a higher LBNSSC than the MCI-AD group. These features could help to differentiate MCI-LB and MCI-AD.

(University of California - Berkeley) UC Berkeley neuroscientists have found a way to estimate, with some degree of accuracy, a time frame for when Alzheimer's is most likely to strike in a person's lifetime, based on their baseline sleep patterns. Their findings suggest one defense against this virulent form of dementia -- for which no treatment currently exists -- is deep, restorative sleep, and plenty of it.
