French scientists analysed the data from 12 previous studies, including a total of 1.85 million participants, and say they found people with a diagnosis of ADHD in childhood were more likely to develop a psychotic disorder later in life. Although this type of study cannot show that having ADHD actually caused the increased risk of psychotic disorder, the researchers say children with ADHD should be followed-up beyond the age of 18. They also recommend further studies to investigate how these disorders could be biologically linked and whether early intervention for ADHD might reduce the risk of subsequent psychotic disorders.
