• Feel-good hormone helps jog memory, finds study of seniors - Science Daily, 11/8/12 - "Half of the test participants had first taken a placebo and the remainder had taken Levodopa. This substance, also known as L-DOPA, is able to reach the brain from the bloodstream, and there it is converted into dopamine ... after six hours memory performance changed. Test subjects with Levodopa recognised up to 20 per cent more photos than the members of the comparison group. The ratio between the amount of Levodopa taken and the body weight of the test subjects proved to be decisive for an optimal dose" - Yeah but I think if I remember correctly, you buildup a tolerance to Levodopa and it no longer works.  IAS sells it.

• Elevated Plasma Homocysteine Levels in Patients Treated With Levodopa: Association With Vascular Disease - Archives of Neurology, 1/03 - "Levodopa therapy, rather than PD, is a cause of hyperhomocysteinemia in patients with PD. Deficiency of folate or vitamin B12 levels does not explain the elevated homocysteine levels in these patients"
