One of the well-recognized problems of long-term L-3,4-dihydroxyphenylalanine
(L-DOPA) therapy in the treatment of Parkinson’s disease is the development of
L-DOPA induced dyskinesia. These abnormal movements cause significant disability
and narrow the therapeutic window of L-DOPA. Cell transplantation is one of the
most promising upcoming therapies for the treatment of Parkinson’s disease, and
may help alleviate or avoid L-DOPA-induced dyskinesia. However, the more recently
acknowledged phenomenon of graft-induced dyskinesia is posing a major obstacle to
the success of this treatment. This motor side-effect closely resembles abnormal
movements induced by chronic L-DOPA treatment, yet they remain after withdrawal
of the medication indicating their origins lie in the transplant. In this review,
we compare these two therapy-induced adverse effects, from the way they manifest
in patients to the possible mechanisms underlying their development.
