Attention deficit hyperactivity disorder (ADHD) is found to be due to genetic cause and not from bad parenting or bad diet, a study published recently in the journal Lancet says. The finding was based on the analyses of the genomes of 366 kids diagnosed with ADHD that were compared to the genomes of 1000 children comprising the control group.
Children with ADHD were found to have duplicated or missing segments in their DNA and overlapping of said segments called copy number variants (CNV). The presence of CNV along with genetic variants associated with autism and schizophrenia, strongly suggests that ADHD is is a neuro-developmental disorder that is highly hereditary.
Considered one of the most common mental disorders in children, ADHD symptoms include being easily distracted, impulsive, restless, and often having troubles at home and in school.
