Harm prevention policies must take the long view The maintenance of brain health is central to health and wellbeing across the lifespan.1 Evidence suggests three periods of dynamic brain changes that may be particularly sensitive to the neurotoxic effects of alcohol: gestation (from conception to birth), later adolescence (15-19 years), and older adulthood (over 65… Continue reading Lifetime perspective on #alcohol and #brain health

Acute social #isolation evokes midbrain craving responses similar to #hunger
When people are forced to be isolated from each other, do they crave social interactions? To address this question, we used functional magnetic resonance imaging to measure neural responses evoked by food and social cues after participants (n = 40) experienced 10 h of mandated fasting or total social isolation. After isolation, people felt lonely and craved social… Continue reading Acute social #isolation evokes midbrain craving responses similar to #hunger
Cognitive impairment and #sedentary behavior predict health-related attrition in a prospective longitudinal #Parkinson’s disease study
In Parkinson's disease (PD), the high burden of motor and non-motor symptoms, such as cognitive impairment or falls, is associated with rapid disease progression and mortality. This is often reflected by an increased drop-out rate of PD patients in longitudinal studies. Active physical behavior can impact the disease course beneficially and has an overall positive… Continue reading Cognitive impairment and #sedentary behavior predict health-related attrition in a prospective longitudinal #Parkinson’s disease study
Partial and Total #Sleep Deprivation Interferes with Neural Correlates of Consolidation of #Fear Extinction #Memory
We assessed the impact of total and partial sleep loss on neural correlates of fear conditioning and extinction learning and recall in healthy young adults. Methods Participants (56.3% female, age 24.8±3.4) were randomized to a night of normal sleep (NS, n=48), sleep restriction (SR, n=53), or sleep deprivation (SD, n=53). All completed fear conditioning and… Continue reading Partial and Total #Sleep Deprivation Interferes with Neural Correlates of Consolidation of #Fear Extinction #Memory
#Dementia and the risk of death in elderly patients with #COVID‐19 infection: Systematic review and meta‐analysis
The COVID‐19 infection represents a global public health emergency worldwide. Several risk factors have been associated with a poor prognosis among COVID‐19 patients. We aimed to perform a systemic review and meta‐analysis to evaluate the mortality risk in elderly patients with dementia and COVID‐19 infection.. ..A total of 233 articles were retrieved; 158 were excluded… Continue reading #Dementia and the risk of death in elderly patients with #COVID‐19 infection: Systematic review and meta‐analysis
Polypill with or without Aspirin in Persons without #Cardiovascular Disease
..Using a 2-by-2-by-2 factorial design, we randomly assigned participants without cardiovascular disease who had an elevated INTERHEART Risk Score to receive a polypill (containing 40 mg of simvastatin, 100 mg of atenolol, 25 mg of hydrochlorothiazide, and 10 mg of ramipril) or placebo daily, aspirin (75 mg) or placebo daily, and vitamin D or placebo… Continue reading Polypill with or without Aspirin in Persons without #Cardiovascular Disease
#Ticagrelor Added to #Aspirin in Acute Ischemic #Stroke or Transient Ischemic Attack in Prevention of Disabling Stroke A Randomized Clinical Trial
Reduction of subsequent disabling stroke is the main goal of preventive treatment in the acute setting after transient ischemic attack (TIA) or minor ischemic stroke.. ..Ticagrelor (180-mg loading dose on day 1 followed by 90 mg twice daily for days 2-30) or placebo within 24 hours of symptom onset. All patients received aspirin, 300 to… Continue reading #Ticagrelor Added to #Aspirin in Acute Ischemic #Stroke or Transient Ischemic Attack in Prevention of Disabling Stroke A Randomized Clinical Trial
N,N-dimethyltryptamine compound found in the hallucinogenic #tea ayahuasca, regulates adult neurogenesis in vitro and in vivo
N,N-dimethyltryptamine (DMT) is a component of the ayahuasca brew traditionally used for ritual and therapeutic purposes across several South American countries. Here, we have examined, in vitro and vivo, the potential neurogenic effect of DMT. Our results demonstrate that DMT administration activates the main adult neurogenic niche, the subgranular zone of the dentate gyrus of… Continue reading N,N-dimethyltryptamine compound found in the hallucinogenic #tea ayahuasca, regulates adult neurogenesis in vitro and in vivo
#Delirium In Severe Acute Respiratory Syndrome- #Coronavirus -2 Infection: A Point Of View
Coronavirus disease 2019 was for the first time reported in December 2019 in China, and has since spread throughout the world as a pandemic. In this point of view, we aim to discuss the occurrence of central nervous system symptomatology, and delirium, in patients suffering coronavirus disease 2019. To date, most of the research done… Continue reading #Delirium In Severe Acute Respiratory Syndrome- #Coronavirus -2 Infection: A Point Of View
