Frontotemporal dementia is associated with alterations in immune system function
Researchers discovered increased inflammatory activity in a subgroup of patients with frontotemporal dementia. The increased inflammation was indicated by elevated levels of cytokines known to increase inflammatory response and decreased levels of IL-10, which reduces inflammation. The inflammation was associated with Parkinsonism's symptoms and rapid cognitive and functional decline. The study also revealed patients with FTD are less likely to develop cancer.... Read More...
Brain networks more stable in individuals with higher cognitive abilities
Higher intelligence was associated with higher temporal stability of brain network modularity. Brain regions of the dorsal attention network contributed most to the observed effect.... Read More...
New insights into biological underpinnings of schizophrenia
Researchers identified ten genes, that when disrupted, significantly increase the risk of schizophrenia. Two of the genes were associated with glutamate receptors. The findings suggest the decreased function of the glutamate receptors drives symptoms of schizophrenia.... Read More...
Researchers discover potential therapy to treat detrimental effects of marijuana
Prenatal exposure to THC makes dopamine neurons hyperactive and increases the sensitivity to the behavioral effects of the compound during pre-adolescence. This may increase the risk of developing schizophrenia later in life. However, treatment with pregnenolone, a drug under clinical trials for ASD, cannabis use disorder, and schizophrenia, appears to correct the brain abnormalities and behavioral problems associated with prenatal cannabis exposure....

Happy, angry or neutral expressions? Eyes react just as fast
The initial reaction of the brain is independent of the facial emotional expression we see. It is only after the eye movement is completed that the brain shows strong responses to the emotional expression of a face.... Read More...
Stress during pregnancy may affect baby’s sex and risk of preterm birth
Stress and depression during pregnancy can affect the fetus' sex and increase the risk of preterm birth. Mothers who experienced physical and psychological stress during pregnancy were less likely to have a baby boy. During pregnancy, the fetuses of stressed mothers had reduced heart rate movement coupling, indicating slower central nervous system development.... Read More...
Introduce standard units for cannabis to improve mental health
Introducing and prescribing standard units for cannabis, which make people aware of the concentrations of THC in the product, could help improve mental health treatments and outcomes.... Read More...
Self-reported suicide attempts rising in black teens as other groups decline
Self-reported suicide attempts rose significantly in African American teens, while they fell in teens of other ethnic backgrounds throughout an almost 20-year study. Researchers report suicide attempts increased at an accelerating rate in African American female teenagers, even as overall female suicide attempts declined.... Read More...
Is bipolar disorder associated with increased risk of Parkinson’s disease?
Study reveals patients with bipolar disorder have a significantly increased risk of developing Parkinson's disease compared with the general population.... Read More...

A new brain mapping study allows for individual predictions of the progression of frontotemporal dementia.... Read More...
Gut immunity more developed before birth than previously thought
The fetal gut has far better developed immune capabilities than previously thought. The findings could help develop new maternal vaccines and provide early insight into potential autoimmune disorders, which may occur later in life.... Read More...
