The Archives of Neurology & Psychiatry began publication in 1919 and, in 1959, became 2 separate journals: Archives of Neurology and Archives of General Psychiatry. In 2013 their names changed to JAMA Neurology and JAMA Psychiatry, respectively. JAMA Neurology is an international peer-reviewed journal published 12 times a year; the online version is published on the second Monday of the month, with new content posted every Monday. A Middle Eastern edition is published bimonthly. The journal publishes occasional theme issues on topics such as cerebrovascular diseases, epilepsy, neuromuscular diseases, neoplasms, multiple sclerosis, movement disorders, Alzheimer disease, neurotherapeutics, genetics, sleep disorders, headache syndromes, emergency neurology, neuro-ophthalmology, neuro-otology, neurogenerative diseases, ethical issues, and neurobiotechnology. The acceptance rate is 16%. The average time from submission to acceptance is 48 days; from acceptance to publication is 6 months. Its 2011 impact factor is 7.58 (the impact factor is a measure of citation rate per article, and is calculated by dividing 1 year's worth of citations to a journal's articles published in the previous 2 years by the number of major articles [eg, research papers, reviews] published by that journal in those 2 years). The editor is Roger N. Rosenberg, MD, Zale Distinguished Chair and Professor of Neurology at the University of Texas, Southwestern Medical Center, in Dallas.
