The trend to legalize cannabis is not yet accompanied by a solid body of research that would assure the parents of an adolescent, for example, that the use of cannabis from an early age is harmless. Indeed, some recent research suggests that at least some young users may be at considerable mental health risk if they regularly ingest high-potency cannabis. Dr. Martin Paulus, a researcher and expert on how substance use affects the brain, explains what we know and don't know, and offers advice for parents of adolescents.

We write about a novel idea to address brain-based disorders that has moved from theory to bedside in only 3 years. Called closed-loop neuromodulation, it involves using electrical stimulation—delivered via an implanted deep-brain stimulation (DBS) device—at a precise location in the brain. The stimulation occurs intermittently throughout each day for only seconds at a time, and only at moments when a sensor placed in another part of the brain detects a specific EEG brain-wave pattern linked with the onset of a patient’s depressed moods. In its first clinical test, a treatment-resistant patient experienced a remission.

Her research has shown that these children are at greater risk for developing an anxiety disorder by school age. She also discusses sensory oversensitivity and autism spectrum disorder.
