Herein we report the successful acute and long-term remission of psychotic symptoms and catatonia with the combination of clozapine and ECT in a 26-year-old female with moderate ID and treatment-resistant schizophrenia. To our knowledge, this is the first case example of the successful use of the combination of bilateral, standard-pulse ECT and clozapine in both acute and long-term treatment of treatment-resistant schizophrenia and catatonia in an adult with ID. Our report adds further support to the emerging evidence regarding the efficacy and safety of this combination in treatment-resistant schizophrenia.

Catatonia in Autistic Adults in a Tertiary Inpatient and Outpatient Neurodevelopmental Service: A Retrospective Review / Syeda HASAN in Journal of Autism and Developmental Disorders, 56-10 (October 2026)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 56-10 (October 2026) . - p. 4025-4034 Titre : Catatonia in Autistic Adults in a Tertiary Inpatient and Outpatient Neurodevelopmental Service: A Retrospective Review Type de document : texte imprimé Auteurs : Syeda HASAN, Auteur ; Pushpal DESARKAR, Auteur ; Yona LUNSKY, Auteur ; Anupam THAKUR, Auteur Article en page(s) : p. 4025-4034 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Catatonia is a syndrome that affects movement, speech and behaviours, in varying degrees of severity. There is an increasing research interest in catatonia in autistic adults. Bulk of the studies are in children and youth, and few have reported on clinical presentation and treatment outcomes of catatonia in autistic adults. The aim of the study is to determine the prevalence, clinical characteristics and treatment outcomes for catatonia in adults with autism spectrum disorder in a tertiary neurodevelopmental service. This retrospective chart review was carried out to identify autistic adults presenting with catatonic symptoms. Wing and Shah criteria for catatonia were used for confirmation of the diagnosis. Out of 143 individuals with a confirmed diagnosis of autism spectrum disorder, sixteen (11.1%) of them were identified to have catatonic symptoms and co-occurring intellectual disability Commonly reported catatonic symptoms included difficulties in initiating actions (n = 16), posturing (n = 14), freezing (n = 6), and reduced motor movements (n = 16). Eleven (11) of them responded rapidly to lorazepam (dose range 6 mg– 24 mg). One participant received ECT with full improvement in catatonic symptoms, and two declined. The prevalence rate of catatonia (11.1%) in autistic adults in the tertiary neurodevelopmental service, a specialized setting, is similar to previous studies. Most study participants showed complete resolution of symptoms with a combination of high dosages of benzodiazepines and psychosocial interventions. Use of specific tools for diagnosis of catatonia in autism spectrum disorder, such as Wing and Shah’s criteria, can help with diagnostic accuracy.

Prevalence of Psychotropic Medication Use and Psychotropic Polypharmacy in Autistic Adults With or Without Intellectual Disability / Kazunari YOSHIDA ; Yona LUNSKY ; Daniel MULLER ; Pushpal DESARKAR in Journal of Autism and Developmental Disorders, 55-2 (February 2025)

We conducted a retrospective medical chart review of outpatients with an autism diagnosis aged 18 years and older. The rates of psychotropic medication use and psychotropic polypharmacy were compared between autistic adults with and without ID. Subsequently, logistic regression analyses were performed to identify factors associated with psychotropic medication use and psychotropic polypharmacy in autistic adults with ID and those without ID, respectively. The rates of prevalence of psychotropic medication use and polypharmacy were significantly higher in participants with ID than those without ID (78.6% vs. 58.8% and 49.3% vs. 31.2%; p-values < 0.05). Age, gender, race, residence, presence of mood disorders, presence of schizophrenia, absence of anxiety disorder, number of psychiatric comorbidities, and presence of behaviors that challenge were significantly associated with these outcomes, depending on the presence/absence of ID. The need to optimize pharmacotherapy in autistic adults, stratifying by the presence of ID, is highlighted.

Psychopharmacological treatment of challenging behaviours in adults with autism and intellectual disabilities: A systematic review / Amanda SAWYER in Research in Autism Spectrum Disorders, 8-7 (July 2014)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 8-7 (July 2014) . - p.803-813 Titre : Psychopharmacological treatment of challenging behaviours in adults with autism and intellectual disabilities: A systematic review Type de document : texte imprimé Auteurs : Amanda SAWYER, Auteur ; Johanna K.

Adults with Autism and intellectual disability have a high incidence of challenging behaviour, defined as repetitive self injurious or aggressive behaviour. We underwent a systemic review of the evidence for treating challenging behaviours in adults with Autism and intellectual disability. Methods A literature search was conducted using three large databases to extract studies on the treatment of challenging behaviour among adults with Autism and intellectual disability. Papers, which met this criterion, were reviewed and analysed to assess study evidence and quality. Results Seven articles were selected which included five agents: fluvoxamine, sertraline, clomipramine, risperidone, and ziprasidone. Randomized control studies of fluvoxamine and risperidone, provided efficacy for the treatment of challenging behaviour in adults with Autism and intellectual disability. Open label trials of sertraline, clomipramine and ziprasidone were also effective in treating challenging behaviours for this population. Discussion Risperidone and fluvoxamine provided the best evidence for treating challenging behaviour, and risperidone was the only medication with multiple trials showing its efficacy. Further studies are required to demonstrate the efficacy of psychopharmacology in treating challenging behaviours among adults with Autism and intellectual disability.

Task-based functional neural correlates of social cognition across autism and schizophrenia spectrum disorders / Lindsay D. OLIVER in Molecular Autism, 15 (2024)  

Public ISBD [article]  inMolecular Autism > 15 (2024) . - 37p.

Despite evidence for comparable group-level performance in lower-level emotion processing and higher-level mentalizing, limited research has examined the neural basis of social cognition across these conditions. Our goal was to compare the neural correlates of social cognition in autism, SSDs, and typically developing controls (TDCs). METHODS: Data came from two harmonized studies in individuals diagnosed with autism or SSDs and TDCs (aged 16-35 years), including behavioral social cognitive metrics and two functional magnetic resonance imaging (fMRI) tasks: a social mirroring Imitate/Observe (ImObs) task and the Empathic Accuracy (EA) task. Group-level comparisons, and transdiagnostic analyses incorporating social cognitive performance, were run using FSL's PALM for each task, covarying for age and sex (1000 permutations, thresholded at p < 0.05 FWE-corrected). Exploratory region of interest (ROI)-based analyses were also conducted. RESULTS: ImObs and EA analyses included 164 and 174 participants, respectively (autism N = 56/59, SSD N = 50/56, TDC N = 58/59). EA and both lower- and higher-level social cognition scores differed across groups. While canonical social cognitive networks were activated, no significant whole-brain or ROI-based group-level differences in neural correlates for either task were detected. Transdiagnostically, neural activity during the EA task, but not the ImObs task, was associated with lower- and higher-level social cognitive performance. LIMITATIONS: Despite attempting to match our groups on age, sex, and race, significant group differences remained. Power to detect regional brain differences is also influenced by sample size and multiple comparisons in whole-brain analyses. Our findings may not generalize to autism and SSD individuals with co-occurring intellectual disabilities. CONCLUSIONS: The lack of whole-brain and ROI-based group-level differences identified and the dimensional EA brain-behavior relationship observed across our sample suggest that the EA task may be well-suited to target engagement in novel intervention testing. Our results also emphasize the potential utility of cross-condition approaches to better understand social cognition across autism and SSDs.
