Background Several studies have shown that afternoon napping promotes cognitive function in the elderly; on the other hand, some studies have shown opposite results. This current study further examined the relationship between afternoon napping and cognitive function in the ageing Chinese population. Methods A total of 2214 elderly were included (napping group: n=1534; non-napping group:… Continue reading Relationship between afternoon #napping and #cognitive function in the ageing Chinese population

Association of Medical #Stimulants With #Mortality in the US From 2010 to 2017
The role of nonopioids in the drug overdose epidemic in the US is frequently overshadowed. From 2015 to 2016, mortality rates involving cocaine and psychostimulants were smaller than opioids, but were rising faster than opioids.1 We examined individual substances listed on death certificates to better understand stimulant-associated mortality and assess rates over time. https://bit.ly/3oEgFbP
Increased #alcohol use during the #COVID-19 pandemic: The effect of mental health and age in a cross-sectional sample of social media users in the U.S.
The COVID-19 pandemic has triggered a public health crisis of unprecedented scale. Increased alcohol use has been extensively documented during other crises, particularly among persons with anxiety and depression. Despite COVID-19's differential impact by age, the association of age, mental health and alcohol use during the pandemic has not been explored. This study aimed to… Continue reading Increased #alcohol use during the #COVID-19 pandemic: The effect of mental health and age in a cross-sectional sample of social media users in the U.S.
Increased Risk of #Parkinson’s Disease in Patients With #Schizophrenia Spectrum Disorders
PD comorbid with schizophrenia has been considered rare because these diseases associate with opposite alterations in the brain dopamine system. The objective of this study was to investigate the risk of PD after a diagnosis of a schizophrenia spectrum disorder. Methods Regionally, this was a retrospective record‐based case–control study. The cohort included 3045 PD patients… Continue reading Increased Risk of #Parkinson’s Disease in Patients With #Schizophrenia Spectrum Disorders
The effects of #alcohol and #cannabis use on the cortical thickness of #cognitive control and salience brain networks in emerging adulthood: a cotwin control study
Background Impairments in inhibitory control and its underlying brain networks (control/salience areas) are associated with substance misuse. Research often assumes a causal substance exposure effect on brain structure. This assumption remains largely untested and other factors (e.g., familial risk) may confound exposure effects. We leveraged a genetically-informative sample of 24-year-old twins and a quasi-experimental cotwin… Continue reading The effects of #alcohol and #cannabis use on the cortical thickness of #cognitive control and salience brain networks in emerging adulthood: a cotwin control study
Longitudinal Associations of Midlife Accelerometer Determined #Sedentary Behavior and Physical Activity With #Cognitive Function: The CARDIA Study
To determine if accelerometer measured sedentary behavior (SED), light‐intensity physical activity (LPA), and moderate‐to‐vigorous–intensity physical activity (MVPA) in midlife is prospectively associated with cognitive function. Participants were 1970 adults enrolled in the CARDIA (Coronary Artery Risk Development in Young Adults) study who wore an accelerometer in 2005 to 2006 (ages 38–50 years) and had cognitive… Continue reading Longitudinal Associations of Midlife Accelerometer Determined #Sedentary Behavior and Physical Activity With #Cognitive Function: The CARDIA Study
A Randomized Controlled Trial of Repeated #Ketamine Administration for Chronic Posttraumatic Stress Disorder
Posttraumatic stress disorder (PTSD) is a chronic and disabling disorder, for which available pharmacotherapies have limited efficacy. The authors’ previous proof-of-concept randomized controlled trial of single-dose intravenous ketamine infusion in individuals with PTSD showed significant and rapid PTSD symptom reduction 24 hours postinfusion. The present study is the first randomized controlled trial to test the… Continue reading A Randomized Controlled Trial of Repeated #Ketamine Administration for Chronic Posttraumatic Stress Disorder
State-dependent responses to intracranial brain stimulation in a patient with #depression
Deep brain stimulation is a promising treatment for severe depression, but lack of efficacy in randomized trials raises questions regarding anatomical targeting. We implanted multi-site intracranial electrodes in a severely depressed patient and systematically assessed the acute response to focal electrical neuromodulation. We found an elaborate repertoire of distinctive emotional responses that were rapid in… Continue reading State-dependent responses to intracranial brain stimulation in a patient with #depression
Efficacy and safety of #antidepressants for the treatment of back pain and #osteoarthritis: systematic review and meta-analysis
.. 33 trials (5318 participants) were included. Moderate certainty evidence showed that serotonin-noradrenaline reuptake inhibitors (SNRIs) reduced back pain (mean difference −5.30, 95% confidence interval −7.31 to −3.30) at 3-13 weeks and low certainty evidence that SNRIs reduced osteoarthritis pain (−9.72, −12.75 to −6.69) at 3-13 weeks. Very low certainty evidence showed that SNRIs reduced… Continue reading Efficacy and safety of #antidepressants for the treatment of back pain and #osteoarthritis: systematic review and meta-analysis
