Predisposing Risk Factors for Functional Limb Weakness
A common symptom of functional neurological disorder is functional limb weakness. It is diagnosed based on positive features of internal inconsistency. The hallmark of functional limb weakness is the existence of internal inconsistency revealing a pattern of symptoms governed by abnormally focused attention. Adverse childhood experience arises as a clear risk factor for functional motor disorders but also varies largely according to the setting and duration of symptoms and is not present in the majority of patients.
