ADHD Medications Unlikely To Improve School Performance In Kids Without ADHD
BOSTON (CBS) — Many college students who don’t have ADHD illegally use ADHD medications, like Adderall and Ritalin, to try to boost their performance in school. But is that a smart way to go? Probably not, according to a new study from the University of Rhode Island and Brown University. Researchers looked at 13 undergrads and found that Adderall did improve attention and focus but that did not result in better performance of tests. The drug also appeared to impair working memory. This was a very small study so more research is needed, but in the meantime, students who don’t have ADHD should be discouraged from taking these drugs.
Nature, Published online: 24 June 2019; doi:10.1038/d41586-019-01949-2A molecular dialogue between neurons and star-shaped cells called astrocytes in the striatum of the mouse brain leads to behavioural hyperactivity and inattentiveness that are reminiscent of attention-deficit hyperactivity disorder.
ConclusionsOur results suggest a causal role of insomnia in autism spectrum disorder and bipolar disorder. Future disease models should include insomnia as a factor for these two disorders to develop effective interventions. More detailed mechanism studies may also be inspired by this causal inference.
Hi all! I've recently become interested in pursuing the premed path (again) and am in need of some (or a lot of) advice. I've been scouring these boards for a while now to answer my own q's and have read some great advice but still kind of confused on how I should approach some of this. So I've decided to come out of lurkedom and make my first post. I have a lot of questions so please, bear with me... So I did really poorly in my undergrad years due to undiagnosed ADHD through some of it... BSN to MD

Abnormal functional brain asymmetry and deficient response inhibition are two core symptoms of attention deficit hyperactivity disorder (ADHD). However, it is not known whether these symptoms are inter-related and whether they result from altered frontal excitability or compromised interhemispheric connectivity. We studied these issues in 52 ADHD and 43 non-clinical adults by comparing: (1) stop-signal reaction time (SSRT); (2) frontal asymmetry of the N200 event-related potential component, which is evoked during response inhibition and is lateralized to the right hemisphere; (3) TMS-evoked potential (TEP) in the right fr...

Luheshi, Marie-Ève TremblayAbstractIn addition to their traditional role as immune sentinels, recent discoveries over the last decade have shown that microglial functions now include regulation of neuronal/glial cell migration, differentiation and maturation, as well as neuronal network formation. It was thus proposed that disruption of these microglial roles, during critical periods of brain development, could lead to the pathological onset of several neurodeve...
(Reuters Health) - Children and young adults with chronic conditions like asthma, diabetes, and ADHD may be more likely to develop mental illness than youth who don't have physical health problems, a U.S. study suggests.
We examined whether SCT and processing speed predict different functional correlates within children and adolescents with ADHD. Participants were 193 clinically-referred youth meeting DSM ADHD criteria without comorbid conditions (mean age = 9.9 years, SD = 2.5; age range 6-16). The incremental utility of SCT and processing speed to predict (1) adaptive functioning and (2) academic achievement, after controlling for age, sex, medication status, and ADHD symptom burden, was assessed using hierarchical multiple regressions. SCT symptoms significantly predicted adaptive functioning, accounting...
