Sleep Deprivation and the Brain: An Hour-by-Hour Guide to Cognitive and Emotional Effects
In this video, Dr. Sanil Rege, Consultant Psychiatrist, takes you through the hour-by-hour impact of sleep deprivation based on systematic reviews. From heightened emotional reactivity at 24 hours, to visual distortions at 48 hours, to full-blown hallucinations at 72 hours and psychosis-like symptoms at 120 hours—this is what happens when the brain is pushed to its limits.
Explore the neurobiological mechanisms behind these changes, including the roles of the amygdala, prefrontal cortex, and dopaminergic systems. This critical analysis offers valuable insights for mental health professionals into sleep’s essential role in neurological stability and psychiatric vulnerability.
