Aleksander Hagen Erga is a Professor in Psychology at the Department of Social Sciences, Faculty of Social Sciences, University of Stavanger. He also holds a dual clinical-research role at Stavanger University Hospital, serving as Head of Research at the Regional Competence Center for Substance Abuse Research (KORFOR) and as a researcher at the Center for Movement Disorders. His work bridges academic and clinical domains, focusing on mental health and cognition in Parkinson’s disease and addiction.
His research interests include clinical psychology, addiction psychology, neuropsychology, cognitive behavioral therapy, impulse control disorders, and longitudinal studies on substance use and recovery. He employs quantitative methods such as cohort studies, longitudinal data analysis, and clinical trials to explore cognitive function, mental health trajectories, and treatment outcomes in both Parkinson’s disease and polysubstance use disorders. He also investigates childhood maltreatment, personality traits, sleep disturbances, and social factors in recovery.
The recent publication trends show a strong focus on dual-pathology populations, particularly those with overlapping cognitive and psychiatric symptoms in neurodegenerative and addictive conditions. His work frequently involves collaborative, interdisciplinary teams and appears in high-impact journals such as Frontiers in Psychiatry, BMC Psychiatry, and Journal of Parkinson's Disease. Many studies use longitudinal designs to track changes over time, emphasizing predictive modeling and clinical implications.
While no formal scientific awards are listed, his leadership in major research centers and consistent publication output indicate significant academic and clinical recognition.
He actively supervises PhD and master’s students, including Elise Constance Grude Fodstad, Anastasia Ushakova, and Jens Hetland. His research is supported through institutional affiliations with KORFOR and the Center for Movement Disorders, suggesting access to clinical data, patient cohorts, and research funding. He is involved in digital mental health initiatives, such as the ePark study on video-assisted CBT for depression in Parkinson’s.
He leads research teams at KORFOR and collaborates with the Norwegian ParkWest study group, focusing on population-based cohorts in Western Norway. His work contributes to national and international understanding of addiction recovery and neuropsychiatric aspects of Parkinson’s disease.
