Sleep is beneficial for learning. However, it remains unclear whether learning is facilitated by non-rapid eye movement (NREM) sleep or by REM sleep, whether it results from plasticity increases or stabilization, and whether facilitation results from learning-specific processing. Here, we trained volunteers on a visual task and measured the excitatory and inhibitory (E/I) balance in… Continue reading Complementary contributions of non-REM and #REM sleep to visual #learning

Nine-year prospective efficacy and safety of brain-responsive #neurostimulation for focal #epilepsy
Prospectively evaluate safety and efficacy of brain-responsive neurostimulation in adults with medically intractable focal onset seizures (FOS) over 9 years.. Adults treated with brain-responsive neurostimulation within 2 year feasibility or randomized controlled trials enrolled into a long-term prospective open label trial (LTT) to assess safety, efficacy, and quality of life (QOL) over an additional 7… Continue reading Nine-year prospective efficacy and safety of brain-responsive #neurostimulation for focal #epilepsy
The temporal association between incident late‐life #depression and incident #dementia
There is an established association between depression and subsequent dementia. The present study examined temporal associations between incident late‐life depression and subsequent dementia, also considering age and sex.. ..Incident depression was associated with a higher risk of subsequent dementia (incidence rate ratios (IRR) adjusted for age and sex: IRR = 1.58, 95% CI = 1.51‐1.64).… Continue reading The temporal association between incident late‐life #depression and incident #dementia
Risk factors of excessive daytime #sleepiness in a prospective population‐based cohort
Although excessive daytime sleepiness is commonly evaluated in clinical and research settings using the Epworth Sleepiness Scale, few studies have assessed the factors associated with its incidence in the general population. We prospectively investigated the predictors of incident and persistent excessive daytime sleepiness in 2,751 subjects (46.1% men, mean age 56.0 ± 9.8 years) from… Continue reading Risk factors of excessive daytime #sleepiness in a prospective population‐based cohort
#Cerebrovascular and Neurological Dysfunction under the Threat of #COVID-19: Is There a Comorbid Role for #Smoking and Vaping?
The recently discovered novel coronavirus, SARS-CoV-2 (COVID-19 virus), has brought the whole world to standstill with critical challenges, affecting both health and economic sectors worldwide. Although initially, this pandemic was associated with causing severe pulmonary and respiratory disorders, recent case studies reported the association of cerebrovascular-neurological dysfunction in COVID-19 patients, which is also life-threatening. Several… Continue reading #Cerebrovascular and Neurological Dysfunction under the Threat of #COVID-19: Is There a Comorbid Role for #Smoking and Vaping?
#Sleep patterns and #insomnia in a large population‐based study of middle‐aged and older adults: The Tromsø study 2015–2016
Epidemiological studies assessing adult sleep duration have yielded inconsistent findings and there are still large variations in estimation of insomnia prevalence according to the most recent diagnostic criteria. Our objective was to describe sleep patterns in a large population of middle‐aged and older adults, by employing accurate measures of both sleep duration and insomnia. Data… Continue reading #Sleep patterns and #insomnia in a large population‐based study of middle‐aged and older adults: The Tromsø study 2015–2016
Circulating asymmetric #dimethylarginine and #cognitive decline: A 4‐year follow‐up study of the 1936 Aberdeen Birth Cohort
The underlying mechanisms leading to dementia and Alzheimer’s disease (AD) are unclear. Asymmetric dimethylarginine (ADMA), an endogenous inhibitor of nitric oxide synthase, may be associated with cognitive decline, but population‐based evidence is lacking.. ..Change in cognitive performance was assessed in participants of the Aberdeen Birth Cohort of 1936 using longitudinal Raven’s progressive matrices (RPM) between… Continue reading Circulating asymmetric #dimethylarginine and #cognitive decline: A 4‐year follow‐up study of the 1936 Aberdeen Birth Cohort
Dual #sensory impairment in older adults and risk of #dementia from the GEM Study
Hearing and vision loss are independently associated with dementia, but the impact of dual sensory impairment (DSI) on dementia risk is not well understood.. ..DSI was significantly associated with higher risk of all‐cause dementia (hazard ratio [HR] = 1.86; 95% confidence interval [CI] = 1.25‐2.76) and Alzheimer's disease (HR = 2.12; 95% CI = 1.34‐3.36).… Continue reading Dual #sensory impairment in older adults and risk of #dementia from the GEM Study
Association of Rapid Eye Movement #Sleep With Mortality in Middle-aged and Older Adults
Rapid eye movement (#REM) sleep has been linked with health outcomes, but little is known about the relationship between REM sleep and mortality.. ..The MrOS cohort included 2675 individuals (2675 men [100%]; mean [SD] age, 76.3 [5.5] years) and was followed up for a median (interquartile range) of 12.1 (7.8-13.2) years. The WSC cohort included 1386… Continue reading Association of Rapid Eye Movement #Sleep With Mortality in Middle-aged and Older Adults
