It has been known for more than 30 years that the efficiency of the dopaminergic treatments can wear off. Currently, motor fluctuations and especially non-motor fluctuations (dysautonomic, cognitive/psychiatric or sensory/pain) remain often underdiagnosed in the first years of treatment. The patient self-questionnaire used in this study has been developed and validated in the United States. Its French version has been tested in daily practice in a study with 938 Parkinson's patients followed-up by movement disorders specialists. Use of this self-assessment patient card has resulted in the detection of fluctuations in 49% of patients, considered nonfluctuating by neurologists after a clinical assessment. The impact of these fluctuations unknown at first is significant, since these motor and/or non motor symptoms are considered troublesome or perturbing for daily life activities by 70% of fluctuating patients. The investigators have recognized the usefulness of this self-assessment in order to detect fluctuations in 81% of fluctuating patients, which lead them to modify the treatment in 76% of them.
