Attention deficit hyperactivity disorder

What is attention deficit hyperactivity disorder?

Attention deficit hyperactivity disorder (ADHD) is a behavioural disorder characterised by inattention, hyperactivity, and impulsivity. The estimated prevalence in children under 18 years in the general population is around 5%. ADHD can persist into adulthood with an estimated prevalence of 2.5% in the adult general population.

What is the evidence for rates of ADHD in people with PTSD?

Moderate quality evidence suggests a small increase in the rate of ADHD in people with PTSD compared to people without PTSD, particularly when compared to traumatised individuals without PTSD. The rate of PTSD was also higher in people with ADHD compared to people without ADHD, and the onset of ADHD was earlier than the onset of PTSD in these samples. These findings suggest a relationship between ADHD and PTSD beyond the effects of exposure to trauma.
