The neuromodulatory fragility hypothesis of Alzheimer's disease pathogenesis
Abstract Sporadic Alzheimer's disease (AD) is associated with numerous risk factors, yet its precise cause remains unclear. Here, we describe a novel framework for AD pathogenesis, whereby diverse risk factors converge on neuromodulatory subcortical systems to confer AD risk or resilience.

Orexin/hypocretin peptide (orexin-A and orexin-B) signaling is believed to take place via the two G-protein-coupled receptors (GPCRs), named OX1 and OX2 orexin receptors, as described in the previous chapters. Signaling of orexin peptides has been investigated in diverse endogenously orexin receptor-expressing cells - mainly neurons but also other ...

Abstract Neuromodulatory subcortical systems (NSSs) are uniquely susceptible to dementia‐related pathology, leading to frequent molecular and behavioral impairments associated with altered function of these nuclei. Some of these systems display clear sex‐specific cytoarchitecture and signaling leading to distinct physiology and behavioral outputs in ...

Wake‐promoting neuromodulators in Alzheimer's disease: Implications for sleep and brain clearance
Abstract Neuromodulatory subcortical systems (NSS) regulate arousal, cognition, and sleep–wake transitions through widespread influence on cortical and subcortical networks. Increasing evidence links dysfunction of these systems to the pathogenesis of Alzheimer's disease (AD). Degeneration and dysregulation of NSS occurs during the preclinical phase of

Glymphatic System Dysfunction in Central Nervous System Diseases
Glymphatic Dysfunction in Neurological Disorders: The glymphatic system is a brain‐wide clearance system that removes neurotoxic waste via AQP4‐mediated CSF‐ISF exchange. Dysfunction through AQP4 mislocalization, BBB injury, and inflammation annihilates clearance and causes acute (stroke, TBI) and chronic disease.

Relationship Between Cognitive Impairments and Serum Orexin Levels in Epilepsy Patients
Objective: Recent studies on neurodegenerative diseases have indicated that Orexin A plays a role in cognitive impairment. Furthermore, animal studies have demonstrated that Orexin A enhances synaptic plasticity in the hippocampus.

Insomnia‐Driven Hippocampal Atrophy: Evidence From Bidirectional Mendelian Randomization
ABSTRACT Background Observational studies link insomnia to hippocampal atrophy, yet causal inference remains limited by confounding and reverse causality. While Mendelian randomization (MR) studies have explored sleep‐brain associations, bidirectional causality between insomnia and hippocampal subfield volumes remains unaddressed.

MicroRNAs in Methamphetamine: Addiction, Neurotoxicity, and Therapeutic Potential
The use of METH leads to the release of dopamine from the affected brain regions, including the nucleus accumbens (NAc), ventral tegmental area (VTA), prefrontal cortex (PFC), hippocampus (Hip), and striatum. This triggers signals that alter miRNA expression, which in turn leads to differential expression of target genes.

The Japanese guideline and criteria for evaluating and determining the effects of psychotropic drugs on motor vehicle driving performance enable the clinical implementation of evidence by assessing “persistence of clinically meaningful impairment”. ABSTRACT The cross‐national differences in automobile driving precautions stated in psychotropic drug ...

ABSTRACT Objective This cross‐sectional study examined associations between sleep, body weight, body composition, appetite, and food reward after bariatric surgery. Methods A single 7‐day study period in 22 female adults (age, 53.5 ± 9.3 years; BMI, 35.5 ± 8.5 kg/m2; body fat: 44.9% ± 8.6%) who underwent bariatric surgery ≥ 1 year prior to enrollment ...
