Early Alzheimer’s Brain Pathology Linked to Psychiatric Symptoms
Researchers report the earliest signs of neurodegeneration associated with Alzheimer's disease are linked to some psychiatric symptoms, including anxiety, depression and sleep disturbances. The findings could lead to earlier diagnosis of Alzheimer's.... Read More...
Why Some Childhood Abuse Victims are More Prone to Developing Certain Mental Illnesses
According to researchers, the severity of mental health problems such as depression, anxiety and PTSD in childhood survivors of abuse may depend upon the time the abuse first took place, how long it lasted and the severity of the abuse. Sexual abuse of females also has a more detrimental effect on mental health than in males, the study reports.... Read More...
Resynchronizing Neurons to Erase Schizophrenia
Researchers report that by increasing the excitability of a subpopulation of hippocampal inhibitory neurons, certain behavioral symptoms associated with schizophrenia can be suppressed.... Read More...
The Evolution of Psychiatric Disorders and Personality Traits
Researchers have identified a gene that has evolved through natural selection and is implicated in psychiatric disorders and personality traits. The study suggests natural selection has helped shaped our psychiatric traits and helped to maintain human diversity.... Read More...

A New Model For How Brain Reward Response May Impact Anorexia
Researchers report the brain's response to taste stimuli is linked to higher anxiety and a drive for thinness in those with anorexia.... Read More...
Beef Jerky and Other Processed Meats Associated with Manic Episodes
A new study reports eating processed meats could contribute to mania associated with bipolar disorder. Researchers found people who had been hospitalized for mania were 3.5 times more likely to have eaten cured meats prior to admittance. ... Read More...
Machine Learning Helps Predict Treatment Outcomes in Schizophrenia
A machine learning algorithm is able to successfully identify, with 78% accuracy, schizophrenia in patients based on brain scans of the superior temporal cortex. The algorithm is also 82% accurate in predicting whether or not a patient will respond positively to a specific antipsychotic medication.... Read More...
Stress Affects People with Schizophrenia Differently
A new study reveals people with schizophrenia have a disrupted stress response. Researchers report those with schizophrenia have an increase in dopamine release in the striatum, but not in the prefrontal cortex, in response to stress.... Read More...
Prenatal Exposure to Folic Acid Fortification of Food May Reduce Mental Health Risks in Children
A new study reports the offspring of women who eat a diet rich of foods fortified with folic acid while pregnant have a reduced risk of being diagnosed with a mental illness later in life. The study reports those who had increased in-utero folic acid exposure had increased cortical thickness and delayed thinning of the cerebral cortex.... Read More...
