CALHM2 V136G polymorphism reduces astrocytic ATP release and is associated with depressive symptoms and Alzheimer's disease risk

This study identifies a genetic variant (CALHM2 V136G) that impairs ATP release from brain cells and is associated with both depression and Alzheimer's disease risk. Using engineered mouse models, researchers demonstrated that this mutation causes depressive-like behaviors and cognitive decline, which could be reversed by ATP supplementation, suggesting a novel biological mechanism linking depression to neurodegeneration.

Gym Usage and Exercise Physiology Services in an Australian Private Psychiatric Hospital: A File Audit

This audit examined the extent of gymnasium and exercise physiologist utilization among 100 patients discharged from a private psychiatric inpatient unit, finding that only 24% had documented gym attendance, with higher usage among those with substance use disorders than affective disorders. The study recommends standardized procedures for exercise assessment and referral, as those potentially most benefiting from exercise coaching were underrepresented in exercise physiology referrals.

Bipolar II Disorder: Understudied and Underdiagnosed

Bipolar II disorder remains underrecognized despite its official diagnostic status since 1994, leading to diagnostic delays averaging over 10 years and inappropriate antidepressant treatment. This review examines differential diagnosis, disease course, comorbidities, and suicide risk while identifying critical gaps in bipolar II-specific treatment research and differences from bipolar I in treatment response.
