abstract="Previous surveillance summaries of administrative data have indicated increases in the incidence and health care burdens of neurological disorders among active component U.S. military members during the last decade. Seventy-eight percent of the increase in average annual numbers of neurological disorders-related outpatient encounters during 2005-2010 is attributable to new diagnostic codes for three common conditions--sleep disorders, pain, and headache. The new codes were added to the International Classification of Diseases as &quot;diseases of the nervous system&quot; between 2005 and 2008. The pre-existing codes for these conditions are in most cases not classified as neurological. Visits for &quot;organic sleep disorders&quot; in particular represented nearly one-half of all outpatient encounters for neurological disorders in 2010. The use of the new diagnostic codes by healthcare providers can mask trends of the &quot;true incidence&quot; of illnesses and injuries and should be considered when interpreting surveillance analyses.<p /> <p>Language: en</p>",
