Although amphetamine drugs can damage dopaminergic axons, it is unknown whether chronic treatment with amphetamine increases the risk of developing Parkinson's disease (PD). Of 1,152 consecutive PD patients, 3 had a prior diagnosis of narcolepsy. This rate is five times higher than expected (p = 0.02). These patients had typical onset of narcolepsy and underwent treatment with amphetamine. Although preliminary, this observation raises the possibility that some factors intrinsic to narcolepsy or its treatment may be a risk factor for PD. © Springer-Verlag 2012.
