Diagnosis of functional (psychogenic) paresis and weakness

Functional (conversion) neurological symptoms represent one of the most common situations faced by neurologists in their everyday practice. Among them, acute or subacute functional weakness may mimic very prevalent conditions such as stroke or traumatic injury. In the diagnosis of functional weaknes...
