Psychogenic tremor in Parkinson’s disease

Letter to the Editor

The correct diagnosis of patients with psychogenic movement disorders is not straightforward, nor is it always easy to differentiate them from patients with organic movement disorders [1]. In addition, psychogenic disorders may arise within the context of established organic diseases [2] and have been described in asymptomatic family members, who carry the mutation, of subjects with an inherited disorder [3]. The phenomenon of overlap between functional and organic neurological disorders (functional overlay) appears to be common in neurological practice, including up to 12 % of all those with neurological diseases [2]. The occurrence of functional overlay within the context of established Parkinson’s disease (PD) has recently been described in a case series by Pareés and co-workers [4]. Here, we describe a further case of psychogenic tremor in a patient with otherwise typical PD.
