To date, there are no behavioral or psychophysiological treatment studies on paroxysmal dyskinesia (PD). PD is a group of debilitating movement disorders that present with severe episodes of dystonia, chorea, and/or ballistic like movements. This is a first case report of a 50-year-old male who received behavioral interventions (e.g., mindfulness, CBT, and biofeedback interventions) to manage his PD episodes in tandem with multidisciplinary treatments (e.g., neurology, psychiatry, etc.). The paper primarily discusses the serendipitous observation of galvanic skin response (GSR) elevations and spikes immediately before and after the onset of PD episodes. GSR volatility was noted in wave amplitude and wave morphology. Graphs are presented to illustrate GSR volatility associate with PD episodes and the reduction of GSR volatility in response to behavioral approaches. The discussion highlights the feasibility of using GSR biofeedback as an adjunct to mindfulness and CBT to manage PD as part of a multidisciplinary treatment approach. Peripherally, issues that related to misclassification of somatic symptoms and related disorders (e.g., psychogenic non-epileptic seizures) and aspects of neurocognitive disorders are discussed. The paper reviews neurological findings, MRI, neuropsychological data, and psychiatric assessment to highlight the dilemma clinician's face and clarify behavioral practices to further the management of PD.
