Essentials: Understanding & Healing the Mind | Dr. Karl Deisseroth

About this video

In this Essentials conversation, Dr. Karl Deisseroth explains the difference between neurology, where measurable signs such as scans and EEGs guide diagnosis, and psychiatry, where disorders like schizophrenia, depression and autism have no blood test or scan and clinicians must rely on words and rating scales. Dr. Deisseroth says reduced speech can itself be a symptom, making diagnosis harder, but argues quantitative tests based on brain circuits and rhythms will likely come. He identifies stigma as psychiatry’s biggest challenge, noting that untreated anxiety lasting a year or more can convert to depression. Dr. Deisseroth describes adjusting vagus nerve stimulation in real time during clinic visits, and discusses brain-machine interfaces and deep brain stimulation, which he says can powerfully help people with OCD even with a single electrode. He closes optimistically, describing his effort in writing to stay rigorously close to the science while conveying hope about relieving suffering.
