HOW DOES DEPRENYL WORK?
Deprenyl is the only drug known to selectively enhance the activity of a tiny region of the brain called the substantia nigra. Substantia nigra is exceptionally rich in dopaminergic (dopamine-using) neurons. Dopamine is the neurotransmitter that regulates such primitive functions as motor control and sex drive. Deficiencies in dopamine result in Parkinson’s disease symptoms. Degeneration of the neurons in the substantia nigra is implicated not only in the development of Parkinson’s disease, but also in the aging process itself. Deprenyl protects against age-related degeneration of the substantia nigra and dopaminergic nervous system. It also protects sensitive dopamin-containing neurons from age-associated increases in glial cells and the MAO-B that they contain. Deprenyl also inhibits the degrading of neurotransmitters and boosts the release of dopamine. Dopamine is crucial to sex drive, fine motor control, immune function and motivation. The steep decline of dopamine containing neuro
