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

Table 4 Correlations between serum hormonal levels and BDI score, and MoCA score in patients with CTTH

		CRH	ACTH	TSH	Cortisol	Free T3	Free T4
BDI	Pearson correlation	.202^*	.285^**	.416^**	.099	.015	− .388^**
BDI	Sig.	p < 0.05	p < 0.01	p < 0.001	.329	.880	p < 0.001
MoCA	Pearson correlation	− .314^**	− .378^**	− .388^**	− .222^*	.089	.372^**
MoCA	Sig.	p < .01	p < 0.001	p < 0.001	p < .05	.376	p < 0.001

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
* Correlation is significant at the 0.05 level
** Correlation is significant at the 0.01 level
