Research provides new evidence that generalized anxiety disorder (GAD) and depressive disorder (DD) have distinct patterns of brain activity. Machine learning analysis of EEG data reveals signature brain features that may enable more accurate diagnosis. Key Facts: DD showed increased beta band power and complexity compared to GAD Brain network connectivity was altered in both …
Deep brain stimulation (DBS) of a brain region called the ventral capsule/ventral striatum (VC/VS) may provide long-term relief for people with severe, treatment-resistant obsessive-compulsive disorder (OCD), according to a new retrospective study.

Researchers have identified a powerful combination of drugs that may help treat alcoholism by reducing cravings and blocking relapse. The dual treatment virtually wiped out binge drinking and heavy drinking in an animal model of alcohol addiction. Key Facts: Rats treated with both a probiotic and antioxidants showed a dramatic 90% decrease in relapse-like binge …
A new study provides preliminary evidence that MDMA-assisted therapy may help reduce alcohol use in people with severe PTSD. Key facts: MDMA-assisted therapy was tested in a phase 3 clinical trial for treating severe PTSD. Participants were allowed to have mild alcohol or cannabis use disorder. Compared to placebo therapy, MDMA therapy led to greater …
Researchers have discovered that a common soil bacterium called Mycobacterium vaccae (M. vaccae) may help reduce stress, anxiety, and inflammation in the brain. Key Facts: M. vaccae is a naturally occurring bacterium found in soil, mud, and water. It is considered harmless to humans. When heat-killed M. vaccae is injected into rats, it reduces stress-induced …
New research suggests we may one day be able to vaccinate against depression, reducing suffering. Key facts: Depression is linked to inflammation in the body and brain. Anti-inflammatory treatments improve depression. Environmental factors like lack of contact with “old friends” (microbes we coevolved with) are increasing inflammation and depression. Probiotics, helminths and vaccines that restore …
Depression and cognitive deficits are common health issues that impact millions of people. Scientists are testing a new drug, NSI-189, to see if it can help treat depression and improve thinking ability. Early research shows promise that NSI-189 may be able to grow new brain cells and connections, which could potentially treat depression and boost …
