Abstract

To synthesize longitudinal evidence of mental health outcomes, including prepandemic symptom measurements, among individuals with preexisting mental disorders during the COVID-19 pandemic.
Symptom exacerbation commonly occurred in bulimia nervosa, binge-eating disorder, substance use disorders and in obsessive-compulsive psychopathology related to contamination, while symptom improvement was consistently observed in bipolar disorders. In autism spectrum, schizophrenia spectrum and posttraumatic stress disorders, contrasting symptom patterns were reported, possibly reflecting differences in preexisting demographic and clinical profiles and contextual influences. Symptoms in depressive and anxiety disorders, anorexia nervosa and obsessive-compulsive psychopathology unrelated to contamination remained largely stable. Across most disorders, individuals with chronic mental disorders or higher prepandemic symptom levels more frequently showed stable or improving trajectories than those with milder presentations or recent-onset disorders.
Given the small number of methodologically diverse studies, definitive statements regarding differential impact of the pandemic across disorders or underlying mechanisms remain premature. Nevertheless, current evidence does not indicate a generalised deterioration in individuals with preexisting mental disorders, including those with the highest prepandemic symptom burden. While some disorder-specific differences emerged, likely reflecting interactions between contextual changes and preexisting disorder processes, the overall picture is more nuanced than frequently portrayed in pandemic-related literature.
