Book excerpt: Edited by Steven L Lewis, MD, Department of Neurological Sciences, Rush University Medical Center, Chicago, Illinois, USA How do you identify which neurologic syndromes occur due to systemic disease? Neurological problems commonly occur in the context of underlying systemic disease, and may even be the presenting symptom of a medical condition that has not yet been diagnosed. Consequently neurologists need to be aware when a neurological presentation might indicate an underlying systemic disorder. Neurological Disorders due to Systemic Disease provides the tools you need to make these connections. The unique neurologic presentation-based approach relates to the common clinical situations you encounter, including: Headache Stroke Movement disorders Neuromuscular disorders Encephalopathies, seizures, myelopathies, neuro-ophthalmologic and neuro-otologic disorders, sleep disorders, and others Major categories of systemic illness are explored for each presentation to guide you towards a likely cause. These include: Endocrine, electrolyte, and metabolic disorders Systemic autoimmune disorders Organ dysfunction and failure, and critical medical illness Systemic cancer and paraneoplastic disorders Systemic infectious disease Complications due to drugs and alcohol Vitamin and mineral deficiencies Written by a leading cast of experts, with a practical approach including ‘things to remember’ for each presentation, Neurological Disorders due to Systemic Disease should be on every neurologist’s desk.
