Diagnosis and therapy of functional tremor a systematic review illustrated by a case report.

ABSTRACT:

Background

Diagnosis of functional movement disorders and specifically functional tremor (FT) (representing 50% of them) remains demanding. Additionally, due to heterogeneity of the disorders, structured concepts and guidelines for diagnosis and therapy are difficult to establish.
