Mental health represents a major challenge to our societies. One key difficulty associated with neuropsychiatric drug development is the lack of connection between the underlying biology and the disease. Nevertheless, there is growing optimism in this field with recent drug approvals (the first in decades) and renewed interest from pharmaceutical companies and investors. Here we review some of the most promising drug discovery and development endeavors currently deployed by industry. We also present elements illustrating the renewed interest from key stakeholders in neuropsychiatric drug development and provide potential future directions in this field.

Objective: Catatonia is a neuropsychiatric disorder that is associated with a range of medical and psychiatric illnesses. Although many single-center studies have been conducted, uncertainty over the population-based incidence and prevalence of the disorder remains. This study reports on the incidence and prevalence rates of catatonia extrapolated from two large epidemiologic studies in the United Kingdom and United States.

Background: We present Phase 1 trial data using the Neuropsychiatric Inventory ("NPI") domains, NPI-delusions and NPI-hallucinations as symptoms of psychosis in participants with Alzheimer's ("AD") receiving IGC-AD1, a combination of low concentration delta 9-tetrahydrocannabinol ("THC") and melatonin. Cannabis use is considered an established risk factor for psychosis in young people. Psychosis is prevalent in AD patients, with around 50% experiencing it, generating safety concerns regarding the use of THC in these patients.

Here, we explored whether underlying biological factors assessed by blood-based biomarkers of neurodegeneration, inflammation and oxidative stress affect apathy treatment response.
Method: A subset of participants from the Apathy in Dementia Methylphenidate Trial 2 (ADMET 2) were included in this study whose blood samples were available at baseline and at the 6-month treatment completion.
Background: CHRFAM7A is a human-restricted gene associated with neuropsychiatric and neurodegenerative disorders. The translated CHRFAM7A protein incorporates into the α7 nicotinic acetylcholine receptor (α7nAChR) leading to a hypomorphic receptor. Mechanistic insight from isogenic iPSC derived neuronal and mononuclear cells demonstrated that CHRFAM7A affects Ca signaling and activates small GTPase Rac1 leading to an actin cytoskeleton gain of function.
