This page is for pediatric patients. For adult patients, see: altered mental status

Background

  • Both cerebral cortices must be affected to cause altered mental status
  • Must quickly determine if coma or lethargy is from diffuse or focal impairment

Clinical Features

  • Depends on cause
    • Diffuse brain dysfunction - lack of focal findings
    • Focal brain dysfunction - hemiparesis, loss of motor tone, loss of ocular reflexes
  • Important to differentiate diffuse brain dysfunction from localized lesion as a patient may appear confused due to visual deficit, dysphasia, etc.
