Early-Onset Schizophrenia and ADHD

Clinical, Neurocognitive and Functional Outcome in Early-Onset Schizophrenia and Attention-Deficit/Hyperactivity Disorder: A 20-Year Follow-up Study.

About the project

In 1994-98 the study "Cognitive deficits in adolescents with schizophrenia or ADHD" was conducted. A group of 19 patients with early-onset schizophrenia  (EOS) was compared with a group of 20 adolescents with ADHD and a group of 30 healthy adolescents on neurocognitive variables. Prof. Rund was the principal investigator and Øie was the Ph.D. student. Seven papers were published.

In the follow-up study of the same subjects in 2004-08 ("Cognitive deficits in adolescents with schizophrenia or ADHD: a 13 year follow-up study") Øie was principal investigator and four papers were published.

The current research project will develop new knowledge about the longitudinal course of the neurodevelopmental disorders EOS and ADHD. The project focuses on the association between clinical symptoms, neurocognition and functional outcome in these disorders, which often persist throughout the life span.

We will study individuals with EOS compared to ADHD at three time points during a 20 year period. The 20 year follow-up study started in May 2015 and will end in April 2018.
