Medication- and toxin-induced neurologic syndromes

Patients who present with mixed clinical neurologic signs and symptoms can be sorted into groups based on the symptom format. Targeted physical examination and evaluation of laboratory results can help quickly segment patients into groups for further workup or admission. The possibility of medication- or toxin-induced neurologic causes must be considered. Medication- and toxin-induced neurologic syndrome is a combination of several symptoms that are induced either by the exposure to or withdrawal of various medications or by toxins, and the symptoms are sometimes difficult to fit into a nice, neat diagnostic package.
