Objective: This study aims to delineate the characteristics of severe self-injurious behaviors (SIB) in a cohort of children with autism and unspecified intellectual developmental disorder (UIDD) (intellectual disability) and examine potential risk factors for developing SIB. Methods: A retrospective chart review studied characteristics of severe…

Irritability and aggression (IA) are highly prevalent in individuals with autism spectrum disorder (ASD). Although clinical correlates of IA in this population have been previously examined, findings from existing studies capturing symptoms as a set of latent variables do not fully explain meaningful associations between the symptoms themselves.…

Prior studies have demonstrated successful irritability treatment using dopaminergic antagonists in autistic patients. The purpose of this pilot study was to assess the effect of dextromethorphan/quinidine (DM/Q) in autistic adults (18-60 years of age). This was a randomized, blinded, crossover, study of 14 patients randomized to DM/Q or a placebo…

Background: Traditional treatment for the behavioural symptoms in autism spectrum disorder (ASD) remains unsatisfactory. There is an urgent need for new, biologically relevant therapies that target both the core and comorbid symptoms that children may experience. This article builds on research previously published by the authors. Method: We…

Nicotinic acetylcholine receptors (nAChRs), particularly the a7 nAChR, are implicated in the pathophysiology of both autism spectrum disorder (ASD) and aggressive behavior. We explored the feasibility, tolerability, and preliminary efficacy of targeting nAChRs using transdermal nicotine to reduce aggressive symptoms in adults with ASD. Eight…
