Our hands are the primary means for motor interaction with the environment, and their neural organization is fundamentally asymmetric: While most individuals can perform easy motor tasks with two hands equally well, only very few individuals can perform complex fine motor tasks with both hands at a similar level of performance.. ..Our results show that… Continue reading Boom Chack Boom—A multimethod investigation of motor inhibition in professional #drummers

#Sleep duration, midday napping, and sleep quality and incident #stroke The Dongfeng-Tongji cohort
..Compared with sleeping 7 to <8 hours/night, those reporting longer sleep duration (≥9 hours/night) had a greater risk of total stroke (hazard ratio [HR] 1.23; 95% confidence interval [CI] 1.07–1.41), while shorter sleep (<6 hours/night) had no significant effect on stroke risk. The HR (95% CI) of total stroke was 1.25 (1.03–1.53) for midday napping… Continue reading #Sleep duration, midday napping, and sleep quality and incident #stroke The Dongfeng-Tongji cohort
Are symptoms of #insomnia in primary care associated with subsequent onset of #dementia? A matched retrospective case-control study
..We investigated the association between dementia diagnosis and recording of insomnia symptoms 5–10 years earlier in primary care. ..We ascertained the presence of insomnia symptoms during a five-year period starting 10 years before the index date. Odds ratios for developing dementia were estimated using logistic regression after controlling for hypnotic exposure and physical and mental health comorbidities.… Continue reading Are symptoms of #insomnia in primary care associated with subsequent onset of #dementia?

Extra virgin #olive oil improves synaptic activity, short‐term plasticity, #memory, and neuropathology in a tauopathy model
In recent years, increasing evidence has accumulated supporting the health benefits of extra virgin olive oil (EVOO). Previous studies showed that EVOO supplementation improves Alzheimer's disease (AD)‐like amyloidotic phenotype of transgenic mice.. ..At the end of the treatment, compared with control mice receiving EVOO displayed improved memory and cognition which was associated with increased basal… Continue reading Extra virgin #olive oil improves synaptic activity, short‐term plasticity, #memory, and neuropathology in a tauopathy model
#Cognitive Decline Over Time in Patients With Systolic #Heart Failure Insights From WARCEF
This study sought to characterize cognitive decline (CD) over time and its predictors in patients with systolic heart failure (HF) ..In logistic regression, CD was independently associated with higher baseline MMSE scores (odds ratio [OR]: 1.13; 95% confidence interval [CI]: 1.07 to 1.20]; p < 0.001), older age (OR: 1.37; 95% CI: 1.24 to 1.50;… Continue reading #Cognitive Decline Over Time in Patients With Systolic #Heart Failure Insights From WARCEF
Playing analog #games is associated with reduced declines in #cognitive function: a 68 year longitudinal cohort study
..Our goal was to examine the association between playing games and change in cognitive function from age 11 to age 70, and from age 70 to 79.. Higher frequency of playing games was associated with higher cognitive function at age 70, controlling for age 11 cognitive function, and the majority of this association could not… Continue reading Playing analog #games is associated with reduced declines in #cognitive function: a 68 year longitudinal cohort study
#Illiteracy, #dementia risk, and cognitive trajectories among older adults with low education
..Analyses included 983 adults (≥65 years old, ≤4 years of schooling) who participated in a longitudinal community aging study. Literacy was self-reported (“Did you ever learn to read or write?”).. ..Illiterate participants were almost 3 times as likely to have dementia at baseline compared to literate participants. Among those who did not have dementia at… Continue reading #Illiteracy, #dementia risk, and cognitive trajectories among older adults with low education
#Particulate matter and episodic #memory decline mediated by early neuroanatomic biomarkers of Alzheimer’s disease
Evidence suggests exposure to particulate matter with aerodynamic diameter <2.5 μm (PM2.5) may increase the risk for Alzheimer’s disease and related dementias.. ..Long-term PM2.5 exposure was associated with increased Alzheimer’s disease pattern similarity scores, which accounted for 22.6% (95% CI: 1% to 68.9%) and 10.7% (95% CI: 1.0% to 30.3%) of the total adverse PM2.5… Continue reading #Particulate matter and episodic #memory decline mediated by early neuroanatomic biomarkers of Alzheimer’s disease
Bedside #Optic Nerve Ultrasonography for Diagnosing Increased Intracranial #pressure: A Systematic Review and Meta-analysis
Optic nerve ultrasonography (optic nerve sheath diameter sonography) has been proposed as a noninvasive, quick method for diagnosing increased intracranial pressure ..Accuracy estimates were similar among studies stratified by patient age, operator specialty and training level, reference standard, sonographer blinding status, and cutoff value. The optimal cutoff for optic nerve sheath dilatation on ultrasonography was… Continue reading Bedside #Optic Nerve Ultrasonography for Diagnosing Increased Intracranial #pressure: A Systematic Review and Meta-analysis
