To determine the impact of post-traumatic stress disorder (PTSD) on headache characteristics and headache prognosis in U.S. soldiers with post-traumatic headache. ⋯ PTSD is prevalent among U.S. Army soldiers with post-traumatic headache. Comorbid PTSD is not associated with more frequent headaches or chronic daily headache in soldiers evaluated at a military neurology clinic for chronic post-traumatic headache. Comorbid PTSD does not adversely affect short-term headache outcomes, although prospective controlled trials are needed to better assess this relationship.

Genome-wide association studies (GWAS) have identified various migraine susceptibility variants. We aim to replicate 5 GWAS-associated polymorphisms (rs1835740, LRP1 rs11172113, TRPM8 rs10166942, PRDM16 rs2651899, and TGFBR2 rs7640453) in the North Indian population. Furthermore, we checked the single nucleotide polymorphisms (SNPs) in strong linkage disequilibrium (LD) with the selected variants. We also undertook to predict the functional effect (in silico) of the variants. ⋯ We report significant influence of rs1835740, LRP1 rs11172113 and PRDM16 rs2651899 polymorphisms on migraine susceptibility in the North Indian population. Finally, we present the first replication study of GWAS-associated polymorphisms in a population other than European.
