Researchers have discovered that non-neuronal brain cells, oligodendrocytes, produce about 30% of amyloid plaques in Alzheimer’s disease. This challenges the neuron-focused understanding of plaque formation and could lead to new therapeutic strategies targeting oligodendrocytes to slow disease progression.
A new study links stronger brain connectivity between the paraventricular thalamus and nucleus accumbens to anhedonia, especially in males with psychiatric symptoms. This discovery could lead to improved treatments for those struggling with pleasure loss.
New research has found that misophonia, a strong emotional reaction to certain sounds, shares genetic links with anxiety, PTSD, and depression, and is associated with personality traits like neuroticism and irritability.
A new study reveals increased pornography use among Swedish adolescents and a narrowing gender gap in responses. Both boys and girls have become more tolerant of pornography but increasingly critical of its societal benefits.
Lower caffeine consumption was linked to a higher risk of memory impairment and worse Alzheimer's disease biomarkers, suggesting caffeine might offer protective effects against cognitive decline. However, more research is needed to confirm any direct benefits.
A study of dark personality traits has found narcissism and everyday sadism to be the strongest predictors of higher sex drive and pornography use, indicating a stronger link between these traits and sexual motivation than previously thought.
Short, light-intensity exercises can increase blood flow to children's prefrontal cortex, according to new research.. These easy-to-implement exercises could help reduce sedentary behavior and enhance brain health in schools.
Psychological distress is associated with problematic social media use, with extended thinking patterns like worry, rumination, and desire thinking potentially playing a significant role in this relationship and contributing to increased cravings for social network use.
Different insomnia subtypes exhibit distinct brain connectivity patterns, suggesting potential for personalized treatments. These findings highlight the need for tailored approaches based on specific brain characteristics to improve insomnia therapy outcomes.
Researchers found that 20% of siblings of autistic children are diagnosed with autism, a significantly higher rate than the general population. This emphasizes the need for early developmental monitoring and support, especially in high-risk families.
A study found that people with addiction-prone personalities are good at coming up with ideas but have trouble choosing the best ones.
Men, especially fathers, face isolation and mental health challenges due to societal pressures to suppress vulnerability. This contributes to the "loneliness epidemic," exacerbating health risks.
Individuals who perceive themselves as having achieved adulthood tend to report better mental health, especially lower negative emotions. These findings suggest that how people view their adult status may influence emotional well-being across life stages.
Recent longitudinal research found that older adults with mild cognitive impairment who engaged more frequently in cognitively stimulating activities maintained better memory, working memory, and attention, suggesting such activities could help slow cognitive decline.
Labeling oneself as addicted to pornography is linked to higher relationship strain and communication difficulties, even after accounting for compulsive behavior. This suggests the stigma of the "addiction" label might harm relationships.
