A new rodent study uncovers a neural circuit in the brain that appears to govern pain-induced anhedonia. Altering the activity of this circuit restored motivation in pre-clinical models of pain.
Researchers investigate why many of us wake in the middle of the night and dwell on our fears.
Both those with schizophrenia and those with social anhedonia have alterations in the social brain network and a diminished correlation with real-world social network size.
Those with a genetic predisposition to clinical depression are more likely to exhibit physical symptoms including migraines, chronic pain, and fatigue, researchers report.
Study finds a link between post-traumatic brain activity and an increase in anxiety symptoms six months after a traumatic event.
Moment-to-moment fluctuations in brain activity over a three-minute period can reliably predict how receptive a person with social anxiety will be to cognitive behavioral therapy.
A new study adds additional evidence to the link between personality traits and Alzheimer's risk. Researchers found brain changes associated with Alzheimer's are visible early on in people with certain personality traits. Those who scored high for neuroticism and low in conscientiousness were at increased risk of developing Alzheimer's.
In mice, protein lactylation occurs in neurons and is correlated with lactate levels. Protein lactylation is enhanced by neural excitation and social stress. Researchers found social stress specifically enhances lysine lactylation of histone H1 proteins.
These research articles involve depression, seasonal affective disorders, grief, pain, sadness, happiness and generally news regarding mental health research.
Increased accumulation of amyloid beta and a reduction of serotonin in the brains of older adults was associated with higher risks for developing depression later in life.
Mothers who report estrangement from their adult children report they often believe their ex-husbands, and the current partner of the child is responsible for the break in their relationships. Additionally, some cite mental health problems experienced by their child as a factor for estrangement.
People living with common allergies such as asthma, hay fever, and atopic dermatitis are at greater risk of developing depression, bipolar disorder, anxiety, and neuroticism. Researchers report the link was likely not causal.
The more a person experiences severe depression through their lifespan, the less they react emotionally to negative faces during current depressive episodes.
Research news involving schizotypal personality, anxiety, paranoia, unconventional thoughts and beliefs is covered.
PTSD research articles are listed here as well as news about stress, pain, fear, painful memories, trauma and mental health information.
