The American Journal of Psychiatry: Experimental Manipulation of the Orbitofrontal Cortex Affects Short-Term Markers of Compulsive Behavior
Individuals with compulsive behavior disorders, such as obsessive-compulsive disorder (OCD), experience compulsions in which the ability to engage in flexible goal-directed behavior is impaired in favor of habitual behaviors. Research from both animal and human studies have indicated that alterations within the orbitofrontal cortex are a key factor in the onset of compulsive behaviors. However, questions remain...
Pitt Psychiatry Investigators Report New Findings in Alzheimer’s Disease and Dementia & Late-Life Depression Research
Acta Neuropathologica: Plasma P-Tau231, A New Biomarker for Incipient Alzheimer's Disease Pathology Scientists including Tharick Pascoal, MD, PhD (Assistant Professor of Psychiatry and Neurology) from Pitt Psychiatry have published the discovery and validation of a new blood biomarker of Alzheimer’s disease which, for the first time, can produce remarkably early detection of the pathology. The quantification of...
University of Pittsburgh School of Medicine Promotes Helmet Karim, PhD, to Assistant Professor of Psychiatry
We are pleased to announce that Helmet Karim, PhD, has been promoted to Assistant Professor of Psychiatry by the University of Pittsburgh School of Medicine. Dr. Karim’s research focuses on the predictive role of the acute neural changes associated with treatment response in major depressive disorder (MDD). He is principal investigator of a National Institute of Mental Health-funded K01 career development award,...
Now in Neuropsychopharmacology: Understanding Contextual Processing of Perception in Depression
In a hundred-year-old film, a man is seen looking at a bowl of soup, then at a child in a coffin, then at a woman on a divan. While the film shows the exact same footage of the man three times, interspersed with the other images, audiences perceived that the man reacted to each scene with separate and distinct facial expressions. This phenomenon suggested that audience interpretations of his expression were...
