Summary: A new study based on data from 18,740 dementia patients suggests that antidepressants may accelerate cognitive decline. Researchers found that patients taking antidepressants, particularly SSRIs like escitalopram, citalopram, and sertraline, experienced faster deterioration compared to those not on medication.While depression itself can worsen dementia symptoms, the findings highlight the...
Brain’s Working Memory Limits Tied to Learning, Not Really Capacity
Summary: A new study reveals that working memory limitations stem from learning challenges rather than storage capacity. Using a computer model of the basal ganglia and thalamus, researchers showed that holding too much information at once confuses the brain, impairing its ability to learn and use stored data effectively.The model...
FDA Approves Adaptive DBS for Parkinson’s People
Summary: The FDA has approved adaptive deep brain stimulation (aDBS), a breakthrough therapy that adjusts in real time to Parkinson’s disease symptoms. Unlike traditional DBS, which delivers constant stimulation, aDBS monitors brain activity and responds with precise electric pulses to prevent stiffness and involuntary movements.Two approved algorithms target the subthalamic...
Mental development and mental health are impacted by negative childhood experiences.
Summary: A decade-long study reveals how childhood adversity alters brain development, increasing risks for mental health disorders and substance use. Researchers found that teens who experienced early adversity showed delayed cognitive control, with unusual brain activity in regions linked to self-regulation.Connectivity between key brain regions was a stronger predictor of...
