Summary
A compelling Neuroscience finding: the hallucinogen psilocybin, a psychedelic, shows promise for repetitive mild head injury. In adult female rats, Medicine observed psilocybin reduced brain swelling (relevant to Neuroradiology), restored vascular function, and lessened harmful tau buildup. Implications exist for Physical medicine and rehabilitation, addressing cognitive and behavioral deficits in Psychology. Psilocybin's neurotransmitter receptor influence on behavior is vital for Psychedelics and Drug Studies, informing broader receptor research like Nicotinic Acetylcholine Receptors Study.
Abstract
Abstract Repetitive mild head injuries incurred while playing organized sports, during car accidents and falls, or in active military service are a major health problem. These head injuries induce cognitive, motor, and behavioral deficits that can last for months and even years with an increased risk of dementia, Parkinson’s disease, and chronic traumatic encephalopathy. There is no approved medical treatment for these types of head injuries. To this end, we tested the healing effects of the psychedelic psilocybin, as it is known to reduce neuroinflammation and enhance neuroplasticity. Using a model of mild repetitive head injury in adult female rats, we provide unprecedented data that psilocybin can reduce vasogenic edema, restore normal vascular reactivity and functional connectivity, reduce phosphorylated tau buildup, enhance levels of brain-derived neurotrophic factor and its receptor TrkB, and modulate lipid signaling molecules.
