Abstract
The pathophysiology of cluster headaches (CHs) involves the trigeminovascular system, the parasympathetic nervous system, and the hypothalamus. Because of the affected hypothalamus, there may be limbic system involvement in CH. To investigate the relationship between depression, anxiety, and alexithymia in CH, to demonstrate that the limbic system is affected. A total of 18 patients with CHs who were outside of cluster period and 18 healthy controls were included. Participants were administered the Beck depression inventory (BDI), Beck anxiety inventory (BAI), and Toronto alexithymia scale-20 (TAS-20). Patients with CHs had significantly higher rates of alexithymia (p = 0.003) and depression (p = 0.014) than controls. There was no significant difference in anxiety levels (p = 0.297) between groups. It was shown that, in addition to previously identified psychiatric disorders, alexithymia can accompany CHs in patients.
