Delving into the causes of attention deficits: Childhood adversity, lost sleep and dopamine
by Nancy Fliesler, Children’s Hospital Boston Credit: Unsplash/CC0 Public Domain New research on the effects of adversity in childhood ties together stress, sleep loss, and attention deficits later in life. It also uncovers some of the underlying brain biology and potential treatment approaches—while revealing a puzzling sex-specific effect. The lab of Takao Hensch, Ph.D., has long...

New study links autism spectrum disorder to disrupted developmental dopamine – ASD
by Eileen Leahy, Chhavi Chauhan, PhD, Elsevier Behavioral analyses in zebrafish with disrupted dopaminergic signaling during development. Credit: The American Journal of Pathology (2024). DOI: 10.1016/j.ajpath.2024.02.014Recent evidence suggests that dopamine plays a crucial role in neural development. In a novel study, investigators demonstrated the link between disrupted developmental dopamine signaling and autism spectrum disorder (ASD)....

Research shows rat neurons increase dopamine immediately after setbacks
by Kyoto University Caption: Brain chemical dopamine enables adaptive reward pursuit to overcome lack of reward and ultimately obtain more rewards. Credit: KyotoU/Hiroko Uchida Dopamine has been known to increase when results are promising and decrease when expectations are not met. However, this role does not explain the ability to overcome disappointment. Now, researchers at Kyoto...

Dopamine deficiency: What you need to know
Dopamine is a neurotransmitter, a type of chemical that sends signals between nerves in the body. A dopamine deficiency may have links to several medical conditions, including depression, Parkinson’s disease, and attention deficit hyperactivity disorder (ADHD). Dopamine plays a part in controlling the movements a person makes, as well as their emotional responses. The right...
