This is because the cells that make and use dopamine in the brain, dopaminergic neurons, are the cells that die in Parkinson’s disease. [5], Carlson collaborated with the drug company Astra AB (now AstraZeneca) during the 1970s and the 1980s.

Arvid Carlsson made fundamental discoveries about the role of biogenic amines as neurotransmitters in the brain. However, when his father died at the age of 76 she, then 71 years old, devoted herself entirely to her favorite area of research, the legal status of Swedish women in the middle ages. Reserpine injections immobilized rabbits, but no one understood why.
Noradrenaline is synthesized in the body from dopamine, which in turn is metabolized from L-dopa.
Prof Arvid Carlsson. Source: Alchetron. My mother had passed a master-of-arts examination and my father a Ph.D. degree at the University of Uppsala. Unfortunately, levodopa, and other drugs that target dopamine levels in the brain, only treat the symptoms of Parkinson’s, they don’t slow down the loss of brain cells that underlie the disease. Despite its simplicity, it plays an important role as a neurotransmitter – chemicals that brain cells use to communicate with one another. [15][16][17] He was a vocal opponent of homeopathy and worked to prevent homeopathic preparations from being classified as medication in Sweden.
He spent five months as a research fellow for the pharmacologist Bernard Beryl Brodie at the National Heart Institute in Bethesda, Maryland, United States, and the change in his research focus to psychopharmacology eventually led to his Nobel Prize. Dr. Carlsson discovered that dopamine was a neurotransmitter in its own right — one with a critical role in movement.

His search for a new specialty led him to the United States and a five-month fellowship with Bernard B. Brodie, an acclaimed pharmacologist at the National Heart Institute (now the National Heart, Lung and Blood Institute in Bethesda, Md.). It was previously thought to be merely a precursor of the transmitter noradrenaline. His brief stint in the Brodie lab reinvigorated Dr. Carlsson’s career, and set him on the path to his Nobel Prize.
Dr. Brodie had been studying reserpine, one of the first drugs introduced specifically to treat schizophrenia, which made it a hot subject for research.
[7], Carlsson was still an active researcher and speaker when he was over 90 years old, and together with his daughter Lena, he worked[12] on OSU6162, a dopamine stabilizer which alleviates symptoms of post-stroke fatigue.
He then found that dopamine was concentrated in the basal ganglia, the portion of the brain that controls movement. In the nigrostriatal tract system, dopamine undergoes autooxidation or oxidative deamination by monoamine oxidase-B, both of which aggravates with age, leading to increased production of peroxides and hydroxyl radicals 41 . Previous studies from these laboratories have revealed that 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) induced acute profound release of dopamine together with a marked reduction in dopamine synthesis.
