[Features of primary forms of headache in multiple sclerosis].

PH were diagnosed in 18.2% of patients with MS, with a much higher prevalence of migraines than tension headache. In addition, female gender and the type of MS are significantly associated with the risk of migraine. Migraine, as a comorbid condition, can aggravate cognitive impairment in patients with MS, characterized by a lower value of the MoCA scale, especially together with the progression of anxiety and depressive disorders. These findings indicate the need for a larger epidemiological study to accurately assess the prevalence of PH in patients with MS in the Smolensk region.
