Camouflaging of autistic characteristics in social situations is hypothesised as a common social coping strategy for adults with autism spectrum conditions (ASC). Camouflaging may impact diagnosis, quality of life, and long-term outcomes, but little is known about it. This qualitative study examined camouflaging experiences in 92 adults with ASC, with questions focusing on the nature, motivations, and consequences of camouflaging. Thematic analysis was used to identify key elements of camouflaging, which informed development of a three-stage model of the camouflaging process. First, motivations for camouflaging included fitting in and increasing connections with others. Second, camouflaging itself comprised a combination of masking and compensation techniques. Third, short- and long-term consequences of camouflaging included exhaustion, challenging stereotypes, and threats to self-perception.

Previous investigations by our group have shown that prenatal exposure to lipopolysaccharide (LPS), which mimics infection by gram-negative bacteria, induces social, cognitive, and communication deficits. For a complete screening of autistic-like behaviors, the objective of this study was to evaluate if our rat model also induces restricted and repetitive stereotyped behaviors. Thus, we studied the self-grooming microstructure. We also studied the neurochemistry of hypothalamus and frontal cortex, which are brain areas related to autism to better understand central mechanisms involved in our model. Prenatal LPS exposure on gestational day 9.5 increased the head washing episodes (frequency and time), as well as the total self-grooming. However, body grooming, paw/leg licking, tail/genital grooming, and circling behavior/tail chasing did not vary significantly among the groups. Moreover, prenatal LPS induced dopaminergic hypoactivity (HVA metabolite and turnover) in the hypothalamus. Therefore, our rat model induced restricted and repetitive stereotyped behaviors and the other main symptoms of autism experimentally studied in rodent models and also found in patients. The hypothalamic dopaminergic impairments seem to be associated with the autistic-like behaviors.

3. Marsack CN, Samuel PS. {{Mediating Effects of Social Support on Quality of Life for Parents of Adults with Autism}}. {J Autism Dev Disord};2017 (May 19)
The aim of this study was to examine the mediating effect of formal and informal social support on the relationship of caregiver burden and quality of life (QOL), using a sample of 320 parents (aged 50 or older) of adult children with autism spectrum disorder (ASD). Multiple linear regression and mediation analyses indicated that caregiver burden had a negative impact on QOL and that informal social support partially mediated the relationship between caregiver burden and parents’ QOL. Formal social support did not mediate the relationship between caregiver burden and QOL. The findings underscored the need to support aging parents of adult children with ASD through enhancing their informal social support networks.

Flexibility is a key component of executive function, and is related to everyday functioning and adult outcomes. However, existing informant reports do not densely sample cognitive aspects of flexibility; the Flexibility Scale (FS) was developed to address this gap. This study investigates the validity of the FS in 221 youth with ASD and 57 typically developing children. Exploratory factor analysis indicates a five-factor scale: Routines/rituals, transitions/change, special interests, social flexibility, and generativity. The FS demonstrated convergent and divergent validity with comparative domains of function in other measures, save for the Generativity factor. The FS discriminated participants with ASD and controls. Thus, this study suggests the FS may be a viable, comprehensive measure of flexibility in everyday settings.
