Childhood ADHD Meds May Lower Later Psychosis Risk

A landmark study reveals that methylphenidate, the most common ADHD medication prescribed to children, does not increase the risk of psychotic disorders like schizophrenia later in life-and may even lower it.

Researchers from University College Dublin and the University of Edinburgh analyzed health records of nearly 700,000 people born in Finland, including about 4,000 diagnosed with ADHD. They found no evidence linking childhood methylphenidate use to higher psychosis rates in adulthood.

Lead researcher Professor Ian Kelleher noted that while roughly 6% of children with ADHD later develop psychosis, the medication itself isn’t the cause. "Correlation does not equal causation," he emphasized.

Intriguingly, children treated with methylphenidate before age 13 showed a slightly reduced long-term psychosis risk-suggesting possible protective effects, though further research is needed.

The findings apply only to methylphenidate, not amphetamine-based ADHD drugs, and do not address adult-onset ADHD treatment.
