The most prevalent conditions were tension-type headache (121.9 million; 95% UI, 109.4 million to 135.1 million), migraine (57.7 million; 95% UI, 50.1 million to 66.1 million), and diabetic neuropathy (17.1 million; 95% UI, 14.4 million to 19.9 million). Conditions with the greatest collective disability were stroke (3.9 million DALYs; 95% UI, 3.5 million to 4.2 million DALYs), Alzheimer disease and other dementias (3.3 million DALYs; 95% UI, 1.6 million to 6.9 million DALYs), diabetic neuropathy (2.2 million DALYs; 95% UI, 1.5 million to 3.0 million DALYs), and migraine (2.1 million DALYs; 95% UI, 0.4 million to 4.6 million DALYs). Compared with age-standardized metrics in 1990, the prevalence of disorders affecting the nervous system was nearly identical (\u22120.2%; 95% UI, \u22121.5% to 1.9%), with decreased attributable deaths (\u221214.6%; 95% UI, \u221218.3% to \u221211.3%) but increased YLDs (9.8%; 95% UI, 4.6% to 16.6%).
