The thoroughly updated Eleventh Edition of this classic retains the organization, practicality, and readability that makes "Merritt's Neurology" one of the most popular texts among neurologists, primary care physicians, and residents reviewing for psychiatry or neurology boards. In 171 short chapters, the book provides the essentials clinicians need on symptoms/signs, diagnostic tests, and neurologic disorders of all etiologies. This edition features new chapters on endovascular surgical neuroradiology and on psychiatric conditions - schizophrenia, mood disorders, anxiety, and somatoform disorders. Other new chapters cover disorders of DNA translation, pachymeningitis, and Hashimoto encephalopathy. Most chapters have been updated to reflect advances in molecular genetics.
