Fatigue, Fogginess, and Sleep Complaints: Presence and Impact on Functioning After Childhood Traumatic Brain Injury

The purpose of this study was to examine the occurrence and impact of fatigue, fogginess, and sleep complaints on functioning at 3, 6, 10, and 16 months after childhood traumatic brain injury (TBI).

Eighty-eight caregivers completed online surveys regarding their children with TBI, with 17 participants included at the final time point. Measures included questions related to demographic and injury characteristics, executive functioning, social relations, health-related quality of life, and fatigue, fogginess, and sleep complaints.

Fatigue, fogginess, and sleep complaints were persistent and ultimately increased at 16 months postinjury. Over half of the participants were experiencing each symptom at 16 months postinjury (i.e., 52.94% fatigue and fogginess, 58.82% sleep complaints). At 16 months postinjury, fatigue was significantly associated with female sex, and fatigue and sleep complaints were significantly associated with lower physical quality of life, but no other differences were found with symptoms and current functioning.

The results of this study support that fatigue, fogginess, and sleep complaints can persist (from baseline, from postinjury, and in fluctuation) chronically for about half of the children with TBI but little association or impact on other domains of functioning. The present study supports the continued investigation of fatigue, fogginess, and sleep complaints after childhood brain injury, but further investigation with a larger sample size is necessary to inform clinical practices for assessment and management, particularly for speech-language pathologists in rehabilitation and educational settings.
