In three young adults (ages 20–25) with mild to moderate autism spectrum disorder and treatment-resistant depression, intranasal esketamine added to standard antidepressants reduced depressive symptoms. Two patients achieved clinical remission at six months, and one showed partial response. Suicidal ideation decreased, but mentalization and social cognition improved only mildly. Subjective quality of life rose substantially for all three. No major side effects occurred. These preliminary observations require confirmation in controlled trials.
Intranasal Esketamine, when added to standard antidepressants, reduced depressive symptoms in three young adults with both treatment-resistant depression and autism spectrum disorder. Two patients achieved full remission and one showed partial remission over six months, with no major side effects. Suicidal thoughts decreased, but abilities related to understanding others' mental states improved only slightly. Quality of life scores rose substantially for all three patients. The authors note the small sample prevents statistical conclusions and call for larger, randomized studies.
Intranasal esketamine rapidly reduces suicidal ideation and depressive symptoms in patients with treatment-resistant depression. Suicidal ideation scores dropped from 1.56 at baseline to 0.78 after one week and to 0.12 after six months. Depressive symptoms improved from a mean Montgomery-Åsberg Depression Rating Scale score of 30.9 at baseline to 17.5 after one week and 9.8 after six months. Male gender was a negative predictor of response; no other baseline variable predicted outcomes. The findings suggest intranasal esketamine is effective for rapid reduction and resolution of suicidal ideation in this population, and gender differences should be considered in treatment planning.
