Attention Deficit Hyperactivity Disorder (ADHD)

Attention deficit-hyperactivity disorder (ADHD) is a neurobehavioral disorder that affects 3-5 percent of all American children. It interferes with a person's ability to stay on a task and to exercise age-appropriate inhibition (cognitive alone or both cognitive and behavioral).

Many arrested individuals in London may have undiagnosed ADHD or autism

Offering screening for neurodivergence to people detained by the police could help ensure access to appropriate support and fairer treatment in the criminal justice system, say Cambridge researchers, after a study suggests that one in two individuals arrested and detained in London may have undiagnosed attention-deficit/hyperactivity disorder (ADHD) and one in 20 may have undiagnosed autism.

No, taking paracetamol while pregnant doesn’t cause autism or ADHD, major review finds

Researchers reviewed nine systematic reviews on paracetamol use during pregnancy and found that while some studies suggested links to ADHD or autism, the evidence was of low quality and confounded by shared familial factors. Sibling-controlled analyses showed no causal relationship between prenatal paracetamol exposure and neurodevelopmental disorders in children.
