Researchers observed that amyloid-beta and tau proteins are associated with a transition from hyperactivity to slower brain activity, which aligns with declines in attention and memory, suggesting potential early indicators of Alzheimer’s disease progression.
Women with ADHD engage in riskier decision-making than men with ADHD, likely due to reduced sensitivity to bodily responses. This difference highlights the importance of considering sex-specific factors in ADHD diagnosis and treatment.
Scientists found disrupted brain connectivity in youth depression, especially in networks tied to introspection and attention. These changes, linked to symptom severity, could help improve diagnosis and treatment by identifying specific neural markers of depression.
Hangxiety, or hangover anxiety, is the intense worry or dread some people feel after drinking alcohol. It stems from brain chemical imbalances, dehydration, or regret over actions while intoxicated, and is worsened by pre-existing anxiety or heavy drinking.
A new study found that in depression, higher levels of gut proinflammatory bacteria are linked to abnormal hippocampal brain activity, suggesting a connection between gut health and brain function through the gut-brain axis.
APOE4 carriers had higher blood-brain barrier permeability, even without cognitive decline or amyloid beta buildup, suggesting early vascular changes that may be linked to Alzheimer’s risk and neurodegeneration.
Tactile massage was found to reduce hyperactivity, improve focus, and ease oppositional behaviors in adolescents with ADHD, suggesting it may complement traditional treatments for managing ADHD symptoms.
Light exposure, especially in the morning, synchronizes the body clock, influencing sleep, focus, digestion, and overall health. Disrupted light timing can harm metabolism, mental health, and increase risks for diseases like diabetes and heart issues.
Sexual and gender minorities face significantly higher rates of social risk factors like isolation, stress, and economic hardship. These disparities highlight the need for policies addressing systemic inequities to improve health and socioeconomic well-being.
A study found untreated hypertension increases Alzheimer's risk by 36% and non-Alzheimer's dementia risk by 69%. Treating hypertension lowers these risks, highlighting the importance of antihypertensive medication.
A single psilocybin dose increased optimism and engagement in rats for two weeks by enhancing reward processing and reducing loss aversion. These findings suggest psilocybin may help address depressive symptoms like withdrawal and pessimism.
Researchers found that methamphetamine and PCP cause a phenomenon known as neurotransmitter switching, impairing memory. This change is reversible, pointing to potential treatments for drug-induced cognitive deficits and related neuropsychiatric conditions.
A new study sheds light on the growing role of artificial intelligence in emotional well-being. Researchers found that venting to an AI chatbot can effectively reduce feelings of anger, frustration, and fear.
Bright light therapy improves remission and response rates in nonseasonal depression, enhances antidepressant effectiveness, and accelerates symptom relief. A meta-analysis of 11 trials highlights its potential as a low-cost, effective adjunctive treatment for depressive disorders.
Recent research identified hundreds of genetic variants influencing brain structure sizes, linking larger volumes to Parkinson’s risk and smaller volumes to ADHD.
