An exploratory study of parent-child association in sensory modulation disorder involving ADHD-related symptoms.

Background: Sensory modulation disorder (SMD) and attention deficit hyperactivity disorder (ADHD) can co-occur and have overlapping symptoms, thus challenging practitioners. This study aimed to phenotypically explore parent-child associations in SMD, and the interplay between SMD- and ADHD-related symptoms in children with SMD and their parents.

Methods: A cross-sectional study examined 70 parents (n = 35 mothers; n = 35 fathers) and their 35 children with and without SMD, aged 4-6 years.
