Half of children with a mental health condition in the United States go without treatment, according to a study published Monday in the journal JAMA Pediatrics.
ADHD is more common than bipolar disorder. As the two conditions can coexist, misdiagnosis can occur.
In this article, we compare bipolar disorder and ADHD. Read on to learn about the symptoms of each and how they can overlap. We also explain treatments and when to see a doctor.
By studying a large number of imaging scans, researchers have identified conditions and behaviors that could make the brain age prematurely, including schizophrenia, bipolar disorder, alcohol use, and the use of cannabis.
For what is thought to be the largest study of its kind, the researchers analyzed brain scans of 31,227 people aged 9 months–105 years.
In a paper that now features in the Journal of Alzheimer’s Disease, they describe how they identified “patterns of aging” from the brain scans.
These were done using single photon emission computed tomography (SPECT) and came from people with psychiatric conditions such as attention deficit hyperactivity disorder (ADHD), schizophrenia, and bipolar disorder. They were all attending a psychiatric clinic that was based at several locations.
The medications share a similar set of possible side effects, risks, and warnings. But there are some small differences between Adderall and Dexedrine that may make one more suitable for some people than others.
Similarities and differences
Dexedrine and Adderall both contain forms of the synthetic compound amphetamine, which is a central nervous stimulant.
A new study shows that healthy people who take attention deficit hyperactivity disorder (ADHD) drugs experience a surge in the neurotransmitter glutamate in key parts of the brain. And that increase in glutamate is associated with subsequent changes in positive emotion.
The findings, published in the journal Neuropsychopharmacology, not only provide clues about how these drugs affect healthy brains, they also hint at a previously undiscovered link between glutamate and mood.
“This is the first time that an increase in brain glutamate in response to psychostimulant drugs has been demonstrated in humans,” said Tara White, an assistant professor in the Brown University School of Public Health and lead author of the new study. “That’s important since glutamate is the major neurotransmitter responsible for excitation in the brain, and affects learning and memory.”
