Parkinsonian micrographia reversed by treatment with weak electromagnetic fields.

Micrographia is one of the characteristic clinical signs of Parkinson's disease (PD) which is linked to striatal dopaminergic deficiency. It has been reported recently that external application of weak electromagnetic fields (EMFs) in the picotesla (pT) range and of low frequency produced dramatic improvements in motor symptoms in Parkinsonian patients indicating that a specific range of electromagnetic energy increases, among others, striatal dopaminergic neurotransmission. In the present communication, I present two fully mediated Parkinsonian patients who, prior to the application of EMFs, drew lilliputian sized figures reflecting the micrographia of the disease. In both patients a series of treatments with pT EMFs produced, in addition to improvement in motor symptoms, a dramatic increase in the size of their drawings with reversal of their micrographia. Since both patients were maintained on dopaminergic medications prior to and during treatment with EMFs it is suggested that Parkinsonian micrographia is related also to abnormalities of nondopaminergic systems which are affected by weak EMFs. This report corroborates previous observations demonstrating the powerful antiParkinsonian effect of pT range EMFs and highlights the unique efficacy of this treatment modality in Parkinsonism.
