People who have other conditions, such as a learning disability or mental health problem, or who have a close family member with attention deficit hyperactivity disorder (ADHD) are among those more likely to be undiagnosed or wrongly diagnosed with something else.
It is thought ADHD is often missed in girls and women. This is because they may not display classic symptoms and for example, be less disruptive at school, the new draft guidance says.
Professor Mark Baker, director of the centre for guidelines at NICE, said: “Not having an accurate diagnosis can have a negative effect on people and their families. It means they cannot access the best treatment and support.
“We’re asking health and social care professionals to be mindful of these groups so that more people can be diagnosed correctly.”

The draft guideline, which updates previous NICE guidance, also makes recommendations about treating and managing ADHD.
Dr Baird continues: “When treating someone with ADHD, it’s important to offer ongoing support and information about their condition. This, along with sharing information across services, can help them adjust when big changes in their life happen, for example, when moving from school to college.”
NICE is seeking comments on the draft guideline until 18 October 2017.
Individuals and members of the public can comment on the proposed recommendations through an organisation that closely represents their views.
UPDATE - NICE published the final updated guidance on ADHD in March 2018.
