“…As predicted, adults with TS also showed greater overall sensory sensitivity and, more specifically, greater sensitivity to taste, touch and vision than adults without TS. These self-reports of hypersensitivity to sensory stimuli supports previous literature suggesting it to be a key feature of TS (Sutherland Owens et al, 2011;Isaacs & Riordan 2020). In contrast to findings reported in children with TS and those reported in adults with ASD (Smith et al, 2019;, in the current study food selectivity was not associated with sensory sensitivity in adults.…”

“…At least 80% of individuals with TS reported heightened perception of sensory stimuli (Belluscio et al, 2011;Isaacs & Riordan, 2020). However, while higher levels of sensory sensitivity have been reported in adults with TS (Cheng et al, 2017).…”

“…For example, sensory sensitivity has been found to underlie high levels of food selectivity and food preferences identified in children with TS (Smith et al, 2020) and children with ASD and ADHD (Ghanizadeh, 2011;Lane et al, 2010;Simpson et al, 2019) as well as also predicting food selectivity and food neophobia in other neurodivergent adults (Kinnaird et al, 2019). Importantly sensory symptoms can remain prominent throughout the life course (Isaacs & Riordan, 2020).…”

Food selectivity has been shown to be more persistent and severe in children with Tourette syndrome (TS) compared to their typically developing peers. The current study aimed to examine differences in food selectivity, food neophobia and avoidant restrictive intake disorder associated behaviours, between adults with and without TS.Fifty-three adults diagnosed with TS were compared to 53 neurotypical adults and completed the following measures online: Adult Eating Behaviour Questionnaire (AEBQ), Nine-Item Avoidant/Restrictive Food Intake disorder screen (NIAS), Food Neophobia Scale (FNS) and the Sensory Perception Quotient (SPQ). Higher levels of food avoidant behaviours, in terms of food fussiness, food neophobia and Avoidant Restrictive Food Intake Disorder (ARFID)-associated behaviours, were identified in adults with TS compared to adults without TS. While heightened sensory sensitivity failed to predict selective eating, greater sensitivity to taste was found to be predictive of food neophobia in TS. These are the first findings to suggest that food avoidant behaviours are more prevalent for adults with TS and signal a need to address health implications.

“…Hypersensitivity has been emphasized as a critical feature for characterizing and understanding autism (Dellapiazza et al, 2018) but also in OCD (Dar et al, 2012). Hypersensitivity emerges as an early marker of developmental characteristic in ASD (Clifford et al, 2013), and could precede the emergence of obsessive–compulsive symptoms, specifically in the context of tics (Isaacs & Riordan, 2020). Several studies reported that hypersensitivity correlated with social communication impairment (Cascio et al, 2019), intellectual disability (Engel‐Yeger et al, 2011), but also repetitive behaviors in ASD (Schulz & Stevenson, 2019).…”

Discriminant value of repetitive behaviors in families with autism spectrum disorder and obsessional compulsive disorder probands

Repetitive behaviors (RB) represent a wide spectrum of symptoms ranging from sensory‐motor stereotypies to complex cognitive rituals, frequently dichotomized as low‐ and high‐order sub‐groups of symptoms. Even though these subgroups are considered as phenomenologically distinct in autism spectrum disorder (ASD) and obsessive–compulsive disorder (OCD), brain imaging and genetic studies suggest that they have common mechanisms and pathways. This discrepancy may be explained by the frequent intellectual disability reported in ASD, which blurs the RB expressivity. Given the high heritability of RB, that is, the diversity of symptoms expressed in the relatives are dependent on those expressed in their probands, we hypothesize that if RB expressed in ASD or OCD are two distinct entities, then the RB expressed in relatives will also reflect these two dimensions. We thus conduct a linear discriminant analysis on RB in both the relatives of probands with ASD and OCD and subjects from the general population (n = 1023). The discriminant analysis results in a classification of 81.1% of the controls (p < 10−4), but poorly differentiated the ASD and OCD relatives (≈46%). The stepwise analysis reveals that five symptoms attributed to high‐order RB and two related to low‐order RB (including hypersensitivity) are the most discriminant. Our results support the idea that the difference of RB patterns in the relatives is mild compared with the distribution of symptoms in controls. Our findings reinforce the evidence of a common biological pattern of RB both in ASD and OCD but with minor differences, specific to each of these two neuro‐developmental disorders. Lay summary Repetitive behaviors (RB), a key symptom in the classification of both OCD and ASD, are phenomenologically considered as distinct in the two disorders, which is in contrast with brain imaging studies describing a common neural circuit. Intellectual disability, which is frequently associated with ASD, makes RB in ASD more difficult to understand as it affects the expression of the RB symptoms. To avoid this bias, we propose to consider the familial aggregation in ASD and OCD by exploring RB in the first‐degree relatives of ASD and OCD. Our results highlight the existence of RB expressed in relatives compared to the general population, with a common pattern of symptoms in relatives of both ASD and OCD but also minor differences, specific to each of these two neuro‐developmental disorders.

“…Sensory integration dysfunctions refer to abnormalities in the processing of sensory stimuli within the following systems: sensory (tactile and proprioceptive), vestibular, auditory, visual, olfactory and gustatory. Symptoms of sensory integration dysfunction are most often manifested by the following features (Isaacs and Riordan, 2020):  increased or decreased sensitivity to stimuli,  inappropriate level of attention,  reduced level of motor coordination,  abnormal level of physical activity,  general behavioral difficulties. The literature on the subject is poor in information on the topic under consideration.…”

Every employer is responsible for ensuring safe and hygienic working conditions. According to the Labor Code and the relevant regulations, the elements of safe and hygienic working conditions in each enterprise are very similar. Differences arise when a specific industry or special psychophysical needs of an employee are taking into consideration. There is a specific group of employees for whom the working conditions organized by the employer in terms of occupational health and safety differ from the average working conditions. In the paper the needs, limitations and psychophysical possibilities of professionally active employees with sensory integration disorders are analyzed. In this purpose the direct interview with elements of open observation was used as the research method. The results presented in this paper are the small part (initial diagnosis) of the large project. Preliminary conclusions confirm the difficulty of adapting employees with sensory integration disorders to a universal work environment and the great need to organize special working conditions for them.
