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 .

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 .
