We are told that we have a disease whose existence has to be taken on faith since there is no way to diagnose it. But if Ldopa fixes you then just take your pills and go home. Trust us. The Ldopa wouldn't helpif you didn't have it, now would it? Well a big Ho Ho Ho!

We wished to determine whether L-DOPA, a common treatment for the motor deficits
in Parkinson's disease, could also reverse the motor deficits that occur during
aging. We assessed motor performance in young (2-3 months) and old (20-21 months)
male C57BL/6 mice using the challenge beam and cylinder tests. Prior to testing,
mice were treated with L-DOPA or vehicle. Following testing, striatal tissue was
analyzed for phenotypic markers of dopamine neurons: dopamine, dopamine
transporter, and tyrosine hydroxylase. Although the dopaminergic markers were
unchanged with age or L-DOPA treatment, L-DOPA reversed the motor deficits in the
old animals such that their motor coordination was that of a young mice. These
findings suggest that some of the locomotor deficits that accompany normal aging
are responsive to L-DOPA treatment and may be due to subtle alterations in
dopaminergic signaling.
