简要总结
Purpose of study: To investigate whether the NMDA antagonist Memantine has a substantial effect of brain metabolism in patients with Parkinson's disease (PD), using Positron Emission Tomography (PET).
Background: Disturbances in brain metabolism is thought to contribute to degeneration of neurons in brain of PD patients. Production of toxic oxygen radicals and presence of too much excitatory neurotransmitter (glutamate) due to over activity is involved. These factors can theoretically be alleviated by memantine.
Hypothesis: Memantine decreases metabolism in areas in PD brain known to be over-active. Decreases in cerebral blood flow and oxygen metabolism in these areas will be the consequence and this can be detected by PET.
