    Author: Botsali A, Kocyigit P, Uran P.
    Journal: J Dermatolog Treat; 2020 Nov; 31(7):734-738. PubMed ID: 30985218.
    Abstract:
    Background: The vulnerable brain regions to isotretinoin are represented as hippocampus and prefrontal cortex, involved in mood regulation as well as coordination of cognitive functions. Adolescence is a critical period with dynamic alterations in neurocognition. Isotretinoin brought concerns about its possible effects on executive functions, attention and memory.Objective: Evaluate the impacts of isotretinoin on neurocognitive functions in adolescents with acne vulgaris and determine the emergence of psychiatric side effects.Materials and methods: Fifty-five adolescent acne vulgaris patients were assigned to either isotretinoin (n = 38) or systemic antibiotic (n = 17) groups. The neuropsychological test battery and psychometric tests were performed before treatment and during treatment with 3-months intervals.Results: Stroop-TBAG form, verbal-auditory digit span, controlled oral word association test and trail making test results improved in the isotretinoin treatment group along with stable scores in the antibiotic group. Children Depression Scale scores of the isotretinoin group showed an increase at 6th month compared to baseline. None of the patients was evaluated as depressive by the psychiatric examination.Conclusions: In a vulnerable age group, our results demonstrate an improvement for neurocognitive functions in isotretinoin patients. The conflicting results suggest distinct mechanisms to be responsible for the effects on affective and cognitive functions.
