Hirota, Tomoya; Deserno, Marie; McElroy, Eoin – Journal of Autism and Developmental Disorders, 2020
Irritability and aggression (IA) are highly prevalent in individuals with autism spectrum disorder (ASD).

Dubé, Céleste; Olivier, Elizabeth; Morin, Alexandre J. S.; Tracey, Danielle; Craven, Rhonda G.; Maïano, Christophe – Journal of Autism and Developmental Disorders, 2022
This study proposes a multi-informant (youth, teachers, and parents) measure of relationship quality with adults for youth with intellectual disabilities (ID). A sample of 395 youth with mild (49.15%) and moderate (50.85%) ID, aged 11-22 (M = 15.82) was recruited in Canada (French-speaking, N = 142), and Australia (English-speaking, N = 253).…

Eckert, Eleanor M.; Dominick, Kelli C.; Pedapati, Ernest V.; Wink, Logan K.; Shaffer, Rebecca C.; Andrews, Howard; Choo, Tse-Hwei; Chen, Chen; Kaufmann, Walter E.; Tartaglia, Nicole; Berry-Kravis, Elizabeth M.; Erickson, Craig A. – Journal of Autism and Developmental Disorders, 2019
Using a dataset involving 415 individuals with irritability, aggression, agitation and self-injury (IAAS) behaviors from the fragile X syndrome (FXS) FORWARD database, we describe the psychopharmacologic management of IAAS and features of the population of persons with FXS treated with drug therapy for IAAS. Among those with FXS exhibiting IAAS,…

Triggers of Aggressive Behaviors in Intellectually Disabled Adults and Their Association with Autism, Medical Conditions, Psychiatric Disorders, Age and Sex: A Large-Scale Study
Peer reviewed Peer reviewed
Direct linkDirect link
Cohen, Ira L.; Tsiouris, John A. – Journal of Autism and Developmental Disorders, 2020
Aggressive behaviors in those with intellectual disability (ID) and autism (ASD) have been linked to a variety of factors including ID level, age, sex, psychiatric disorders, and medical conditions but these factors have not been studied, in large samples, in terms of how they affect the stimuli that trigger aggression. In this survey of 2243…

Crawford, Hayley; Karakatsani, Efthalia; Singla, Gursharan; Oliver, Chris – Journal of Autism and Developmental Disorders, 2019
Self-injurious and aggressive behaviors are common in fragile X syndrome (FXS). However, little is known about the persistence of these behaviors and associated risk markers. We established the prevalence and persistence of self-injurious and aggressive behaviors over eight years in males with FXS, and associations with risk markers. Results…

To date, the phenotypic significance of EEG abnormalities in patients with ASD is unclear. In a population affected by ASD we aimed to evaluate: the phenotypic characteristics; the prevalence of EEG abnormalities; the potential correlations between EEG abnormalities and behavioral and cognitive variables. Sixty-nine patients with ASD underwent…
