ICASA aims to contribute to a substantial decrease in the proportion of ADHD patients developing an addiction/substance use disorder (SUD) and to substantially improve the detection, diagnosis and treatment of patients having both ADHD and SUD.

Biography ICASA members

Mathias Luderer, PhD

Mathias Luderer is a consultant at the Main Mental Health Center (Department of Psychiatry, Psychosomatic Medicine and Psychotherapy at the University Hospital of the Goethe University, Frankfurt am Main, Germany), where he is head of the Addiction Services and is leading the scientific working group ADHD & Substance Use Disorders. He also serves as Drug and Addiction Officer of the Hesse State Medical Association where he helps physicians with substance use disorders find treatment and keeps their patients safe.
He received his medical degree at the University of Heidelberg and his specialisation in adult psychiatry and psychotherapy and his specialisation in addiction medicine at the Central Institute of Mental Health, Germany, where he also earned his PhD.

Mathias Luderer gained interest in the comorbidity of ADHD with substance use disorders (SUDs) from the very beginning of his professional career. Early on, he recognized many patients with SUD where he also suspected ADHD but was confronted with a huge lack of diagnostic and treatment possibilities. With the help of mentors and peers (especially in ICASA) and with clinical experience, he expanded his knowledge to a level where he is considered the top expert on adult ADHD and SUD in Germany.
He contributed to three major national guidelines (cannabis, opioids, alcohol) as an expert for ADHD; due to this, the recommendations from the ICASA consensus papers are now part of these guidelines.

Mathias Luderer led and contributed to a variety of scientific projects (from deep brain stimulation and ultrasound diagnostics to stigma and virtual reality), but his main interest is the co-occurence of ADHD and SUD. He published over 40 articles and was cited over 500 times.

Mathias Luderer was coordinator of the “young talents group” of the German Society for Addiction Research and Addiction Therapy (DG Sucht), and is member of the DG Sucht, member of the German Society for Addiction Medicine (DG Suchtmedizin) and has built a large national clinical and scientific network in the addiction field.

Mathias Luderer is a member of ICASA for over 10 years, and since 01/2024 a member of the board.
