Clinical Neuropsychiatry 

The wide concept of neuropsychiatric disorders with early onset implies a biological aetiology. Autism spectrum disorder, ADHD, severe obsessive-compulsive disorder and intellectual disabilities are conditions included in the umbrella term.

Individuals with these difficulties suffer from an increased risk of anxiety, depression and other psychiatric problems and an increased risk of somatic symptoms and disorders. Some of the problems can be explained by a genetic vulnerability, but there are also other factors such as immunological or endocrine factors that may contribute to impaired psychiatric and somatic health. As adults these patients have problems with dealing with everyday life and to find a suitable job. Many of them have suffered from peer victimization in childhood, and loneliness and impaired quality of life as adults.

The research group has systematically identified symptoms and disabilities of adults with ADHD and autism spectrum disorder. We have evaluated stimulant treatment in ADHD and developed a psychotherapeutic/psycho-educational treatment program for adult autism spectrum disorder. We have also taken interest in co-existing psychiatric and somatic symptoms, motor skills, gender identity aspects, risk factors for bullying and rating scales for evaluating autistic and obsessive- compulsive symptoms (RAADS-14 Screen and BOCS).

We have also studied brain blood flow with PET scan in adults with autism spectrum disorder.  

Current and future studies involve brainstem audiometry as a method for assisting in diagnosing psychiatric disorders, dental health among adults with autism spectrum disorder and ADHD, motor skills, obsessive-compulsive disorder with acute debut (possibly related to an autoimmune reaction), the effect of sex hormones on the brain and the relevance of vitamin D for mental health.

We conduct research for large and very important groups of psychiatric patients with life-long disabilities  but also with big assets that are seldom utilized. The research results are directly applicable to clinical practice.

Research Projects

  • Gender aspects and biological parameters in adults with autism spectrum disorder
  • A follow-up study on patients with possible Pediatric Acute-onset Neuropsychiatric Syndrome (PANS) and a validity study of the laboratory panel used for diagnosing PANS
  • Biological markers and neurophysiological measures for psychiatric diagnosis
  • Dental health in adults with ADHD and in autism spectrum disorder
  • Bullying and motor functioning
