Alterations in Monoamine Metabolites in Alzheimer's Disease: A Comprehensive Meta‐Analysis of Cerebrospinal Fluid Levels [PDF]
Alzheimers DementAbstract Background Alzheimer's disease (AD) is a neurodegenerative disorder marked by cognitive decline and neuropsychiatric symptoms. The monoaminergic system, crucial for mood, cognition, and behavior regulation, is implicated in AD pathology. Alterations in monoamine metabolites like 3,4‐dihydroxyphenylacetic acid (DOPAC), 5‐hydroxyindoleacetic ...

Psychopathology and 5-hydroxyindoleacetic acid excretion [PDF]
Journal of Psychiatric Research, 1965 Abstract Schizophrenics and nonschizophrenics do not differ in urinary excretion of 5-hydroxyindoleacetic acid on either a concentration or 24 h basis, nor do they differ in variability of excretion. Although a pattern was observed of decreasing psychopathology with increasing 5-hydroxyindoleacetic acid excretion, this pattern may be related to ...

Regulatory Pathways of Monoamine Oxidase A during Social Stress
Frontiers in Neuroscience, 2017 Social stress has a high impact on many biological systems in the brain, including serotonergic (5-HT) system—a major drug target in the current treatment for depression. Hyperactivity of hypothalamic-pituitary-adrenal (HPA) axis and monoamine oxidase A (
