Is the link btwn Adolescent SSRI use & Bipolar Disorder causal? Our study suggests: 𝐍𝐨. When accounting for unmeasured confounding (e.g., depression severity) via Instrumental Variable analysis, the evidence for a causal link disappears. mentalhealth.bmj.com/content/28/1... #Psychiatry #MedSky

What % of all kids in the UK come to child and adolescent mental health services (CAMHS) at some stage in childhood (0 - 18)? 15 years ago, it was 1 in 17 children. Now it’s a pretty staggering 1 in 5 www.cambridge.org/core/journal...

I wrote a blog back in May about 30-year trends in self-reported psychological distress. Have things changed? From the 1990s to the early 00s-- not so much. But from the 2010s onwards-- possibly, and most evidently for young people.

Our new research on whether SSRIs curb the risk of later psychosis. We used quasi-experimental methods with the entire Finnish national birth cohort and, sadly, we find no evidence for a protective effect. Secondary prevention needs to be more radical in it's thinking about SMI prevention.

Out today in BJPsych: 45% of people with a psychotic or bipolar disorder attended CAMHS in Wales at some point in childhood/adolescence🧒 This replicates similar findings from Finland by @iankellehermd.bsky.social & co - showing this applies to UK CAMHS as well. doi.org/10.1192/bjp....

@iankellehermd.bsky.social and co previously demonstrated that ~50% of those with psychosis and bipolar disorder had been to CAMHs in Finland. That was no fluke, as they have now demonstrated that it's 45% in wales. Great work by @kirstieohare.bsky.social 👏 👏 Paper: doi.org/10.1192/bjp....

Shared characteristics associated with both psychotic experiences and likelihood of being treated with stimulant medications may instead be driving the relationship.

Concerns have been raised that stimulant medications could increase risk of psychotic experiences in young people. Our new research shows no evidence for such a causal relationship 💊🧠 Paper 👇 publications.aap.org/pediatrics/a...

Adolescents hospitalised for non-psychotic disorders have a high risk of psychosis in adulthood. But do (attenuated) psychotic symptoms predict later psychotic illness? The answer isn’t necessarily what you might expect… Open access in #PsychologicalMedicine

New research shows >50% of specialist adult mental health service use comes from former #CAMHS patients We need early intervention in childhood to change these poor long-term outcomes That's why we need much more research on mental illness prevention in #CAMHS 👉 www.cambridge.org/core/journal...
