Finding an effective medication for patients with major depressive disorder is notoriously difficult, with 70% of patients failing to respond to the first drug prescribed and 30% not responding to the first four medications. Complicating matters, genetic mutations can increase psychotropic drug-related adverse events, including hospitalizations. A recent study indicates Myriad Genetics Inc.’s Genesight test can help minimize the risk of these negative events, with a reduction of nearly 40% in psychiatric-related hospitalizations and prescription of medications with significant gene-drug interactions.

Addex Therapeutics has offloaded its portfolio of preclinical allosteric modulation drugs into Neurosterix, a new company that arrives on the scene with a $63 million series A round.

The U.S. FDA granted Neuronetics Inc. clearance for use of its Neurostar advanced therapy as an adjunctive treatment of major depressive disorder in patients aged 15 to 21, making it the first transcranial magnetic stimulation treatment (TMS) cleared for this age group, the company said.

Precision psychiatry got some love at two quite different meetings this week, the European Congress of Neuropsychopharmacology’s New Frontiers meeting and BioEurope Spring. The New Frontiers Meeting, an annual two-day meeting dedicated to cutting-edge issues in brain disease research, focused on big-picture and scientific – at times almost philosophical – questions of how to get to a classification scheme for brain disorders that aligns with the underlying biology.

To Steve Hyman, the manual that clinicians currently use to diagnose mental disorders is an active obstacle to getting a scientific understanding of those disorders. Hyman, who is director of the Stanley Center for Psychiatric Research at the Broad Institute, MIT and Harvard, and a former director of the National Institute of Mental Health (NIMH), listed multiple weaknesses of the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (DSM), whose diagnoses, he said, are “arbitrary, rigid, life-stage and context-insensitive,” as well as blind to the fact that mental disorders exist along a continuum.

Sooma Oy recently raised €5 million (US$5.4 million) in funding to help the company expand access to its transcranial direct current stimulation device which allows patients to treat their depression at home. “This is a significant milestone for us that enables us to help more patients globally and help us develop the company to serve the unmet need,” Tuomas Neuvonen, Sooma's co-founder and CEO, told BioWorld.

Enveric Biosciences Inc. has announced the discovery of multiple, promising novel compounds sourced using the company’s Psybrary platform and proprietary computational chemistry and artificial intelligence (AI) drug-discovery system (Psyai).

Cannabinoid CB2 receptor and serotonin 5-HT1A receptor agonists have emerged as therapeutic options for their antidepressive and anxiolytic properties, apart from being linked to synergistic antinociceptive activity when used in combination in animal tests.

Shionogi & Co. Ltd. is partnering with Fronteo Inc. to develop artificial intelligence (AI)-based diagnostic tools to diagnose mental and neurological disorders more accurately.
