    • Dopamine - Wikipedia

      The basic cause of Parkinson’s disease is damage to the parts of the brain and the nerve fibers that use the neurotransmitter dopamine. Because these areas of the brain and these nerve fibers do not function normally, there are low levels of dopamine, the signals we send to our muscles do not get through or they get through in an incomplete ...

      Carlsson showed that dopamine was also depleted by reserpine, and that the action of L-DOPA was mediated by restoring normal levels of dopamine. Subsequent demonstrations that brain dopamine is concentrated in the basal ganglia suggested a central role for its depletion in Parkinson’s disease, and raised the possibility that L-DOPA might be ...

      Abnormalities in pre-synaptic dopamine turnover or dopamine transporter levels are detectable on functional imaging. Patients lose their sense of smell in the pre-clinical phase of PD. Olfactory dysfunction is found in 70-100% of PD patients and is therefore as common as tremor:

      The high levels of dopamine generated in the periphery as a result of these augmented doses are responsible for the side effects experienced by ST (nausea, vomiting, hypertension). Compound 1 is an aralkylhydrazine that competes with catecholamine-based neurotransmitters (including dopamine) for access to monoamine oxidase (MAO) enzymes.
