162 patients (only men) had been investigated. They are divided into two groups according to age and local war in which they had got taking part: first group - the participants of Afghanistan's war (84 men, middle age 46,3±1,38), and second one - the participants of local war in Chechnya (78 men, middle age 32,7±1,54).

We used Leonhard's questionnaire to reveal the character's accentuation and second edition of International headache classification to determine headache type.

It seems that 113 patients suffer from cephalgia. Another 49 was a control. During the investigation of headache syndrome structure we have shown that most often patients suffer from posttraumatic headache (PH) - 61 men, and tension-type of headache (TTH) - 33 men.

The number of men having got 18 and more in one or several scales of Leonhard's questionnaire is reliable more in the first group both for PH (85,7% and 69,2%) and TTH (85,7% and 68,9%). There were no differences between headache subgroups. But in patients from control group (without headache) the expression of personality changes did not increase during the age (69,6% in first group, 73,1% in second). So chronic pain may be a risk factor for decompensation of personality changes.
