You see a school-age child with sensory concerns. [1]
Examiner: What are sensory processing differences? [1]
Strong answer: Dimensional ways of responding to sensory input that impair participation. Useful teaching patterns include over-responsivity, under-responsivity and seeking. SPD as a stand-alone label is contested; function first. [1]
Examiner: How common are sensory symptoms in autism? [2]
Strong answer: Meta-analyses show elevated sensory modulation symptoms in ASD, confirmed in later updates — clinically important but not pathognomonic alone. [2] [3]
Examiner: First-line management? [4]
Strong answer: Map contexts, exclude medical mimics, change environment, school adjustments, OT for participation goals, treat comorbidity. Do not promise cure. [4]
Examiner: What about Ayres sensory integration evidence? [4]
Strong answer: Mixed/evolving. Systematic reviews urge caution; trials and comparative studies continue. Measure play, self-care and school function. [4] [11]
Examiner: Caregivers refuse a needed procedure because of touch sensitivity. [10]
Strong answer: Tactile defensiveness is not an ethical reason to abandon indicated care. Adapt preparation and supports; proceed safely. [10]
