How acetylcholine in the brain connects to psychosis and thinking problems in schizophrenia
Elucidating Cholinergic Relationships with Psychosis And Cognitive Deficits in Schizophrenia
This project uses a new PET brain scan tracer to look at acetylcholine-related nerve terminals in people with schizophrenia and how they relate to psychosis and thinking difficulties.

What this research studies
You would be invited to have a PET scan using a new tracer that measures the vesicular acetylcholine transporter (VAChT) in brain regions such as cortex, hippocampus, and thalamus. The researchers will compare VAChT levels in people with schizophrenia to healthy volunteers and relate those levels to symptom ratings and cognitive tests. Visits will include clinical symptom assessments and standardized cognitive testing alongside the imaging. The team hopes to identify cholinergic markers that help explain psychosis and cognitive problems and that could point to new treatment targets.
Who could benefit from this research
Good fit: Adults diagnosed with schizophrenia who can attend imaging visits and complete symptom and cognitive testing would be the ideal candidates.
Not a fit: People without schizophrenia or those who cannot undergo PET imaging (for example due to pregnancy, certain medical conditions, or inability to tolerate the scan) are unlikely to gain direct benefit from participating.
Why it matters
Potential benefit: If successful, this work could point to new non-dopamine treatments or biomarkers that better target psychosis and cognitive problems in schizophrenia.
How similar studies have performed: Early drug trials targeting cholinergic receptors have shown encouraging clinical effects and initial PET work with VAChT tracers is promising but still emerging.
