Parkinson’s disease (PD) is a neurodegenerative disease that has a fast progression of motor dysfunction within the first 5 years of diagnosis, showing an annual motor rate of decline of the Movement Disorder Society Unified Parkinson’s Disease Rating Scale (MDS-UPDRS) between 5.2 and 8.9 points. We aimed to determine both motor and non-motor PD symptom… Continue reading #Parkinson’s Disease Motor Symptom Progression Slowed with Multisensory #Dance Learning over 3-Years: A Preliminary Longitudinal Investigation

Dose-Response Meta-Analysis on #Tooth Loss With the Risk of #Cognitive Impairment and #Dementia
To quantify the dose-response associations between tooth loss and risk of cognitive impairment and dementia. DesignLongitudinal studies that examined the association between tooth loss and cognitive function were systematically searched on 6 databases through March 1, 2020. The study adhered to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting guidelines. Risk estimates were… Continue reading Dose-Response Meta-Analysis on #Tooth Loss With the Risk of #Cognitive Impairment and #Dementia
#Psilocybin induces rapid and persistent growth of dendritic spines in frontal cortex in vivo
Psilocybin ameliorates stress-related behavioral deficit in mice•Psilocybin increases spine density and spine size in frontal cortical pyramidal cells•Psilocybin-evoked structural remodeling is persistent for at least 1 month•The dendritic rewiring is accompanied by elevated excitatory neurotransmission SummaryPsilocybin is a serotonergic psychedelic with untapped therapeutic potential. There are hints that the use of psychedelics can produce neural… Continue reading #Psilocybin induces rapid and persistent growth of dendritic spines in frontal cortex in vivo
T-Type Ca2+ Enhancer SAK3 Activates CaMKII and Proteasome Activities in #Lewy Body Dementia Mice Model
Lewy bodies are pathological characteristics of Lewy body dementia (LBD) and are composed of α-synuclein (α-Syn), which is mostly degraded via the ubiquitin–proteasome system. More importantly, 26S proteasomal activity decreases in the brain of LBD patients. We recently introduced a T-type calcium channel enhancer SAK3 (ethyl-8-methyl-2,4-dioxo-2-(piperidin-1-yl)- 2H-spiro[cyclopentane-1,3-imidazo [1,2-a]pyridin]-2-ene-3-carboxylate) for Alzheimer’s disease therapeutics. SAK3 enhanced the… Continue reading T-Type Ca2+ Enhancer SAK3 Activates CaMKII and Proteasome Activities in #Lewy Body Dementia Mice Model
The temporal representation of #experience in subjective #mood
Humans refer to their mood state regularly in day-to-day as well as clinical interactions. Theoretical accounts suggest that when reporting on our mood we integrate over the history of our experiences; yet, the temporal structure of this integration remains unexamined. Here, we use a computational approach to quantitatively answer this question and show that early… Continue reading The temporal representation of #experience in subjective #mood
#Gut microbes impact #stroke severity via the trimethylamine N-oxide pathway
Clinical studies have demonstrated associations between circulating levels of the gut-microbiota-derived metabolite trimethylamine-N-oxide (TMAO) and stroke incident risk. However, a causal role of gut microbes in stroke has not yet been demonstrated. Herein we show that gut microbes, through dietary choline and TMAO generation, directly impact cerebral infarct size and adverse outcomes following stroke. Fecal… Continue reading #Gut microbes impact #stroke severity via the trimethylamine N-oxide pathway
Passive transfer of #fibromyalgia symptoms from patients to mice
Fibromyalgia syndrome (FMS) is characterized by widespread pain and tenderness, and patients typically experience fatigue and emotional distress. The etiology and pathophysiology of fibromyalgia are not fully explained and there are no effective drug treatments. Here we show that IgG from FMS patients produced sensory hypersensitivity by sensitizing nociceptive neurons. Mice treated with IgG from… Continue reading Passive transfer of #fibromyalgia symptoms from patients to mice
Predictive factors of #smell recovery in a clinical series of 288 #COVID-19 patients with olfactory dysfunction
To evaluate potential predictive factors of smell recovery in a clinical series of 288 patients presenting olfactory dysfunction (OD) related to the COVID19. Potential correlations are sought between epidemiological, clinical and immunological characteristics of patients and the persistence of OD at 60 days. MethodsCOVID-19 positive patients presenting olfactory dysfunction were prospectively recruited from three European… Continue reading Predictive factors of #smell recovery in a clinical series of 288 #COVID-19 patients with olfactory dysfunction
Serial #sarcomere number is substantially decreased within the paretic #biceps brachii in individuals with chronic hemiparetic #stroke
A muscle’s structure, or architecture, is indicative of its function and is plastic; changes in input to or use of the muscle alter its architecture. Stroke-induced neural deficits substantially alter both input to and usage of individual muscles. We combined in vivo imaging methods (second-harmonic generation microendoscopy, extended field-of-view ultrasound, and fat-suppression MRI) to quantify… Continue reading Serial #sarcomere number is substantially decreased within the paretic #biceps brachii in individuals with chronic hemiparetic #stroke
