From: Cognitive performance in patients with chronic tension-type headache and its relation to neuroendocrine hormones

  CRH ACTH TSH Cortisol Free T3 Free T4
BDI Pearson correlation .202* .285** .416** .099 .015 − .388**
Sig. p < 0.05 p < 0.01 p < 0.001 .329 .880 p < 0.001
MoCA Pearson correlation − .314** − .378** − .388** − .222* .089 .372**
Sig. p < .01 p < 0.001 p < 0.001 p < .05 .376 p < 0.001
  1. BDI = Beck’s Depression Inventory, MoCA = Montreal Cognitive Assessment, CRH = corticotropin-releasing hormone, ACTH = adrenocorticotropic hormone, TSH = thyroid-stimulating hormone, FT3 = free triiodothyronine, FT4 = free thyroxine, significance level was set at p < 0.05
  2. * Correlation is significant at the 0.05 level
  3. ** Correlation is significant at the 0.01 level
