Mar 25th 2025, 11:56

An adult brain affected by attention deficit disorder with or without hyperactivity (ADHD) presents modifications similar to those observed in individuals suffering from dementia. These are the findings of a study which shows that, compared with healthy individuals, patients with an ADHD diagnosis have more iron in certain regions of their brain along with higher levels of neurofilaments[1] (NfL) in their blood. These markers have been consistently reported to be characteristic of old age-related dementias such as Alzheimer's disease and can be measured in its early stages. The study confirms that ADHD may be linked to an increased risk of developing dementia later in life and it provides first evidence for a neurological mechanism possibly involved.

Researchers developed olfactory tests -- in which participants sniff odor labels that have been placed on a card -- to assess people's ability to discriminate, identify and remember odors. They found that participants could successfully take the test at home and that older adults with cognitive impairment scored lower on the test than cognitively normal adults.
