Abstract

BACKGROUND:

The annual incidence of traumatic brain injury in Europe amounts to 235 per 100 000 persons. About two-thirds will develop posttraumatic brain injury chronic fatigue (pTBI-CF).

AIM:

To identify the reversible hormonal and nonhormonal causes of pTBI-CF.

PATIENTS AND METHODS:

Ninety patients with varying degrees of pTBI-CF underwent endocrine testing and an evaluation of sleep, attention, coping style, daily activity and dependency, physical performance, emotional well-being, and quality of life.

RESULTS:

Vitamin D deficiency was found in 65%, poor sleep quality in 54%, anxiety disorders in 36%, growth hormone deficiency in 16%, and gonadal hormone deficiencies in 9%. Fatigue severity was correlated with poor sleep (R = +0.65, P < .0001), serum 25-hydroxy vitamin D levels (R = -0.50, P < .0001), and anxiety (R = +0.50, P < .0001) but not with growth hormone deficiency or gonadal hormone deficiencies. The first 3 factors together explained 59% of the fatigue score variance.

CONCLUSIONS:

Poor sleep, vitamin D deficiency, and anxiety were the most important factors associated with pTBI-CF. Appropriate treatment of these disorders may help to reduce fatigue in these patients.
