The research, publiseh at European Neuropsychopharmacology journal, was carried out based on the PADRIS‑PRESTO cohort, which integrates data from the Catalan public health system, and it compared the prevalence of dementia and stroke among people with severe mental health disorders, such as schizophrenia, bipolar disorder, or major depression, and the population without any psychiatric diagnosis.
The results show that the prevalence of dementia is significantly higher in the group with severe mental disorders in all age groups. Furthermore, the risk of stroke is also higher, above all in young and middle-aged adults, although these differences tend to reduce over the years.
“This study confirms that severe mental disorders not only affect mental health, but are also closely related to other neurological and cardiovascular diseases,” explains Eduard Vieta, head of the Psychiatry and Psychology Service of the Hospital Clínic and leader of the IDIBAPS Bipolar and depressive disorders group. “This is forcing us to rethink the patient care model towards a more comprehensive vision”.
The study has been jointly led by Eduard Vieta, Diego Hidalgo‑Mazzei and Gerard Anmella, with Michele De Prisco and Vincenzo Oliva as first-named author, and it has also enjoyed the participation of a large part of the research team from the IDIBAPS multidisciplinary Translational research programme for brain disorders.
According to Michele De Prisco, a researcher from the IDIBAPS research group: "Our results suggest that severe mental disorders should be considered risk factors for dementia and stroke, especially at ages when these pathologies are not usually expected". This fact highlights the need to bring prevention and clinical surveillance programmes forward among this population.
This study opens the door to improving the early detection of neurological and cardiovascular complications in people with severe mental disorders, with the ultimate goal of reducing morbidity and improving the quality of life of these patients.
