I. General Principles

F. Mild traumatic brain injury

Mild head injury is defined as duration of loss of consciousness of less than 30 minutes. Clinically, patients may appear stunned, dazed, drowsy, indifferent, disoriented, or may have headache, nausea or vomiting. Mild traumatic brain injury is a leading cause of neurological morbidity and can have devastating effects on the lives of patients and families. Mild TBI often goes undetected and significant disability may occur. Management includes psychological counseling, pharmacological treatment and neurorehabilitation. Neurological sequelae may include:  

  • Cognitive impairment   (e.g. memory dysfunction, impaired concentration)
  • Emotional changes (e.g. depressed, anxious, mood fluctuations)
  • Behavioral changes (e.g. more impulsive, more easily angered)
  • Somatic changes (e.g. headache, fatigue, dizziness, sleep disturbances)
