Child and adolescent mental health researcher at university college Dublin and university of Edinburgh.
New research using an emulated target trail approach with all adolescent CAMHs users in Finland suggesting that Doxycycline (an antibiotic) can reduces future risk of schizophrenia.
Massive congrats to @iankellehermd.bsky.social @edinburghcapsych.bsky.social

PPI representatives from the RCSI PSI-STAR study have collaborated with Brokentalkers on 'The Mirror Stage' - a performance inspired by the lived experience of psychosis.

It premieres at Project Arts Centre, Dublin (5–12 Nov) and The Everyman, Cork (18 Nov).

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 now: No evidence that SSRI treatment for adolescent depression reduces future risk of psychosis. This goes against the belief that typical treatments for common mental disorders will reduce the risk of psychosis. 💊🧠

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 👏 👏

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 💊🧠

Very nice work by @valentinakieseppa.bsky.social on whether psychotic symptoms predict future risk of psychosis in CAMHs inpatient users. ⬇️⬇️

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…

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
