Abstract
OBJECTIVE: To study the prevalence and characteristics of Sensory processing abnormalities (SPAs) in children with autism and to study if there is any correlation between sensory processing abnormalities with FDG-PET findings in children with severe autism. METHODS: One hundred children, aged 3-12 y, diagnosed as Autistic spectrum disorder; ASD (DSM-V) and 100 age and sex matched controls were studied. SPAs were detected using Short sensory profile (SSP) questionnaire. Children with progressive neurological diseases, active epilepsy and structural brain abnormalities were excluded. On Childhood Autism rating scale, 30 children had severe and 70 had mild-moderate autism. The pattern of sensory processing abnormalities in children with severe ASD was compared with mild-moderate ASD. FDG-PET scan was done in children with severe autism and correlated with SPAs. RESULTS: All children with severe autism had sensory processing abnormalities as compared to only 40% children with mild-moderate autism. Underresponsiveness/seeking-sensation was affected in all children with severe ASD and 82% had movement sensitivity. In children with mild-moderate ASD, 45% had auditory filtering, 30% had movement sensitivity and 27% had underresponsiveness/seeking-sensation. FDG-PET was abnormal in 17% of children with severe autism. Diffuse cerebral/ temporal lobe hypometabolism, increased bilateral frontal lobe uptake and moderate reduction in parietal lobe (Lt > Rt) was observed. CONCLUSIONS: All patients with severe autism had SPAs. However, they did not correlate with FDG-PET findings.
