How do these issues affect you?
The failure to support people with ADHD, who are at high risk for unemployment, drug abuse, homelessness, suicide, imprisonment and worse, is economically inefficient and ends up wasting taxpayers’ money.
Here are some more stats about the costs of untreated ADHD:
- 46% of kids with untreated ADHD have been expelled. 35% drop out .
- Kids with untreated ADHD have problems with peer relations and end up with fewer friends .
- ADHD is very heritable. If one kid has ADHD there is a 30 to 40% chance that a sibling will have it as well .
- Kids with untreated ADHD have 2 to 4 times more fights with their siblings than their non-ADHD peers .
- They also have 50% more bicycle accidents .
- …and 33% more A&E visits .
- More than half of all parents with ADHD will have a child with ADHD .
- It shouldn’t come as a surprise that adults with untreated ADHD have problems with low self-esteem .
- Young adults with untreated ADHD show 2.6 times the number of sexual partners and 9 times the number of pregnancies compared to their non-ADHD peers .
- Likewise, they show 4 times the number of STD and are 2.5 times more likely to have been tested for HIV/AIDS .
- People with untreated ADHD have 2 to 4 times more car crashes than people without the disorder. And, they are usually far more likely to be the ones at fault [56-58].
- In fact, people with untreated ADHD are 7 times more likely to have had multiple vehicle crashes than people without ADHD .

- People with untreated ADHD end up costing at least twice as much in terms of medical care than they would without the disorder .
Left untreated, ADHD is expensive for everyone.

For some case studies to get an idea of how ADHD affects individuals across their lifespan, we recommend the stories from this Healthwatch report of March 2017. They aren’t long and reveal a lot about how the experiences of people with ADHD add up and impact them in the long run.
