Sensory phenomena related to tics, obsessive-compulsive symptoms, and global functioning in Tourette syndrome

Brain structure in pediatric Tourette syndrome

“…Most TS patients report that tics are often responses to uncomfortable internal sensations, like a tickle in the throat before a cough; some experts conclude that these premonitory sensations may be the primary phenomenon rather than the observed tics. 29 Premonitory sensations in TS are correlated with sensory hypersensitivity 30 and interoceptive awareness, 31 yet peripheral sensation is normal, 32,33 so any sensory abnormality must be central. Since the OFC receives input from most sensory systems and projects to regions involved in visceral function, 34 abnormal white matter connections with OFC fit well with a sensory model of TS.…”

The impact of attention deficit hyperactivity disorder in obsessive‐compulsive disorder subjects

“…They have been defined as all the noncognitive phenomena (e.g., tactile and muscle‐skeletal sensations, “just‐right” perceptions, feelings of incompleteness and premonitory urges) associated with repetitive behaviors (da Silva Prado et al, ; Miguel et al, ; Rosario et al, ). Sensory phenomenon has been described as more frequent in early‐onset (Pérez‐Vigil et al, ; Rayappa et al, ) and tic related OCD (Kano et al, ) subjects. Furthermore, previous studies have reported that almost 65% of OCD subjects have SP and that 15.7% of OCD patients describe them as more severe than the obsessions (Ferrão et al, ).…”

How are Sensory Features associated with seven anxiety disorders in boys with Autism Spectrum Disorder?

“…For example, SF have been described as antecedents for tics in Tourette syndrome (Crossley et al, 2014), and there are some data which report significant decrements in quality of life that are associated with those SF antecedents for tics (Crossley and Eugenio, 2013). Similar data have been reported for obsessive-compulsive disorder (Kano et al, 2015;Sampaio et al, 2014), and it may be that consideration of the association between SF, anxiety and tics or obsessive behaviours might profitably assist in explaining this pathways in people with these disorders and also provide possible intervention points for alleviating their anxiety and the behaviours themselves.…”

“…Now established as one of the key diagnostic criteria for ASD, SF has a greater affect upon functioning in children with ASD than in those without ASD (Ben-Sasson et al, 2009). Although the SF of children on the autism spectrum has not been found to consistently vary with cognitive ability, language levels, or stereotypical behaviour (Klintwall et al, 2011), several studies have linked SF with difficulties in independent functioning and managing daily life (Kern et al, 2006), lower participation in social, physical and related activities, (Hochhauser and Engel-Yeger, 2010) and challenging behaviour in school-age (Tseng et al, 2011) and preschool age children (O'Donnell et al, 2012) with ASD.…”

“…Although the Sensory Profile User's Manual (Brown and Dunn, 2006, p. 1) states that "The profile is most appropriate for children 5-10 years of age", it can be used with older persons, as witnessed by the fact that the author of the SP has used it with children aged 3-13 (Kientz and Dunn, 1997), 3-15 (Ermer and Dunn, 1988) and 6 to almost 17 years (Myles et al, 2004). Other authors have used the SP with samples aged 3-43 years of age (Kern et al, 2007) and 3-56 years of age (Kern et al, 2006) and others have used an abbreviated version of the Sensory Profile in samples aged 4-18 years (Wigham et al, 2014) and 2-17 years (Mazurek et al, 2013). All these studies included samples of people with ASD.…”
