September is National ADHD Awareness Month, and in their ongoing quest for answers, researchers continue to discover new things about the common diagnosis, estimated to affect up to 16% of school aged children and close to 5% of adults. In the United States alone, roughly 8.8 million adults are thought to struggle with the condition.
A new study has found a link between adult ADHD and a certain form of dementia.
After Alzheimer’s, DLB is the second most common form of dementia. DLB stands for, of all things, “Dementia with Lewy Bodies.” Lewy bodies, named after the doctor who discovered them, are spherical protein deposits found in nerve cells that disrupt the normal functioning of the brain’s important chemical messengers.
Currently DBL accounts for 10% of dementia cases (although many doctors think it is vastly underdiagnosed, since it shares some characteristics with Alzheimer’s and Parkinson’s disease).
In a recent study, researchers in Argentina studied 509 people in their 70s (360 of them with DLB) and discovered that nearly half of the men and women who ended up with DLB in their senior years also had adult ADHD. The occurrence of adult ADHD in seniors with DLB was more than three times the rate in the group without DLB.
Dr. Angel Golimstok, one of the authors of the study, says that it looks like the same neurotransmitter pathway problems are involved in the development of both conditions.
