To achieve this, scientists administered L-DOPA, a medication already widely used to treat Parkinson’s disease, which helped elevate dopamine concentrations in the brain. Test subjects showed ...

Previous studies in a rat model of Parkinson disease (PD) have shown that dyskinesia induced by L-DOPA—a treatment-limiting adverse effect of long-term administration—is caused by the release ...

We examined the effect of L-DOPA in the dose used for GH stimulation on the LH,FSH and Pr levels in 9 subjects with Turner syndrome, who had never received estrogens. We found the following (mean ...

She eats them every week and shared her three favorite recipes. Fava beans, also called broad beans, contain levodopa or l-dopa, a chemical that can be converted into the pleasure hormone dopamine.

Parkinson’s disease, characterized by progressive dopamine neuron loss, leads to motor deficits such as bradykinesia and rigidity, as well as nonmotor symptoms like cognitive decline and depression.

However, nicotine may modulate dopamine transmission and has clear motor effects when associated with L-DOPA, reducing L-DOPA-induced dyskinesias. Clinical trials have yielded inconclusive results ...
