The alterations were most pronounced in people who started using cannabis at a young age. The findings reveal potential negative long-term effects of heavy cannabis […]

Prodromal Symptom Patterns May Help Predict Bipolar Disorder

Two antecedent, or prodromal, psychiatric symptom patterns may help to identify young persons at increased risk of developing bipolar disorder, a new analysis suggests. Early signs of bipolar disorder (BD) can fall into a relatively characteristic “homotypic” pattern, consisting mainly of symptoms or other features associated with mood disorders; or a “heterotypic” pattern of other […]

Heightened Anxiety May Be Early Indicator Of Alzheimer’s

An association between elevated amyloid beta levels and the worsening of anxiety symptoms is suggested in a new study. The findings support the theory that neuropsychiatric symptoms could represent the early manifestation of Alzheimer’s disease in older adults. Past studies have suggested depression and other neuropsychiatric symptoms may be predictors of progression of Alzheimer’s Disease […]

Mood Disorders And Epilepsy May Share Genetic Susceptibility

For the first time, scientists at Rutgers University-New Brunswick and Columbia University have found evidence that seizures and mood disorders such as depression may share the same genetic cause in some people with epilepsy. The finding may lead to better screening and treatment to improve patients’ quality of life. Physicians have long suspected there is […]

New Transdiagnostic Subtypes For Mood Anxiety & Trauma Disorders

Researchers have identified five new categories of mental illness that span across current diagnoses of anxiety and depression. The five categories, which researchers define by their specific symptoms and areas of brain activation, are: tension, anxious arousal, general anxiety, anhedonia (the inability to feel pleasure), and melancholia. “We are trying to disentangle the symptom overlap […]
