Study does not establish cause and effect, and experts say it highlights need for further research

People who are diagnosed with attention deficit hyperactivity disorder (ADHD) as adults could be at greater risk of developing dementia later in life, research suggests.

While experts cautioned that the study did not establish whether the apparent link was cause and effect, they say it highlights the need to explore possible connections further and examine whether ADHD medications mitigate any potential dementia risk.

The results come from a study of the medical records of more than 100,000 people, which found those diagnosed with ADHD as adults appear to have almost three times the risk of being diagnosed with dementia later in life.
