Exploring the relationship between dissociative experiences and recovery in psychosis: cross-sectional study

BJPsych Bulletin January 27, 2025 Claudia Calciu, Rob Macpherson, Kerry Rees et al.

Dissociative experiences—compartmentalisation, detachment, and absorption—do not predict stages of recovery from psychosis. A cross-sectional study of 75 individuals with psychosis from recovery services in Gloucestershire used five questionnaires, including the Dissociative Experiences Scale and the Stages of Recovery Instrument. The results indicate no simple relationship between dissociative and psychotic symptoms, suggesting that clinicians should assess these symptoms separately and may need special treatment approaches when dissociative symptoms play a significant role.

The effects of naturalistic cannabis use on cognition and subjective experience in older adults with normal cognitive function

Journal of Psychopharmacology November 3, 2025 P. di Ciano, B. Le Foll, S. Zhao et al.

Older adults aged 65–78 who smoked their preferred legal cannabis with an average THC content of 18.7% showed decreased performance on the trail making test (versions A and B) 60 minutes after smoking, compared to when they were sober. However, the percentage of words retained in a verbal free recall test was significantly higher after cannabis, apparently due to a reversal in performance decrement. Smoked cannabis produced robust subjective drug effects. Correlations between blood THC levels and cognitive performance at 60 and 210 minutes were unclear. The findings suggest that older adults who use cannabis may show decrements on only some cognitive tests, along with marked changes in subjective experience.
