About Susanne Bejerot

Research area: Psychiatry

Susanne Bejerot is Professor of Medical Science. She is a specialist in psychiatry and trained psychotherapist in cognitive-behavioral therapy.  Her research is mainly clinical and focus on symptoms and outcome for people with obsessive-compulsive disorder (OCD), Pediatric Acute-Onset Neuropsychiatric Syndrome (PANS) schizophrenia spectrum disorder, ADHD and autism spectrum disorder (with or without intellectual disability). She has worked with research on pharmacological treatments for OCD, PANS, ADHD as well as psychological treatments for adults with autism or OCD. In recent years she has focused on immunopsychiatry, which is a novel field of research. Clinical and preclinical research support an association between immunological vulnerability and psychiatric illness. This opens new venues for diagnosis and treatments.

Susanne Bejerot has also been conducting research on psychiatric co-morbidity, personality disorders, dental health, vitamin D deficiency, gender identity issues, motor skills, bullying, and psychiatric rating scales. A questionnaire, the PsychoNeuroInflammatory related Signs and Symptoms Inventory (PNISSI) designed to facilitate assessment of complicated psychiatric conditions with suspected inflammation mediated disorder is currently tested (and is freely available on request).

Ongoing studies involve the following projects: Joint hypermobility and its association with ADHD and autism; Symptoms and markers for sudden-onset obsessive-compulsive symptoms (PANS); Internet treatment for adults with autism; Immunological markers in psychiatric patients and Rituximab (an immunomodulatory drug) for treatment of severely ill patients with either OCD or psychosis and Impact of schizotypal personality traits on life quality in individuals with autism.

The goal is clinical anchored research for psychiatric patients with life-long disabilities and substantial needs. In collaboration with researchers at iRiSC and Karolinska Institutet she hopefully will identify biological markers that can provide support for future inflammation modulating treatments for the most severely affected psychiatric patients and find helpful treatment strategies.
