- In their 1957 and 1958 papers [1.2], (Carlsson et al 1957) (Carlsson et al 1958) Carlsson and co-workers made the intriguing observation that the akinetic effects of reserpine could be reversed by an intravenous injection of the dopamine (and noradrenaline) precursor, 3,4- dihydroxyphenylalanine (DOPA).

- Since this early study, research has continued to show an association between dopamine transporters and ADHD. (healthline.com)
- A 2013 study found that the amount of gray matter in the brain might contribute to ADHD more than levels of dopamine. (healthline.com)
- Nonetheless, the research showing an association between ADHD and lower levels of dopamine, as well as higher levels of DTD, suggests that dopamine could be a possible treatment for ADHD. (healthline.com)
- Many medications for treating ADHD work by increasing dopamine and stimulating focus. (healthline.com)
Substances2
- Articles and documentaries describe dopamine as what makes life worth living, the chemical that permits every enjoyable moment to be savored, the "hit" everyone is chasing whether through social media, psychoactive substances, sports, food, sex or status. (scientificamerican.com)
- Therefore, exposure to substances and activities that increase dopamine can become addictive to some individuals. (medicalnewstoday.com)
Release11
