title: Effects of amino acid energy drinks leading to hospitalization in individuals with mental illness.
abstract: OBJECTIVE
  The objective of this case report is to highlight the possible dangers in individuals with prior psychiatric illness of the use of amino acid and caffeine-containing drinks marketed as energy drinks to combat mental and physical fatigue.
  
  
  METHODS
  We report on three patients with known psychiatric illness who demonstrated sequelae following use of these beverages with probable association with clinical deterioration leading to hospitalization.
  
  
  RESULTS
  In all three cases, hospitalizations were associated with deterioration of mental state, manifested, amongst other symptoms, by hypervigilance, psychomotor unease and intensified affected responses.
  
  
  CONCLUSIONS
  While a casual relationship between the use of these drinks and hospitalization cannot be definitively stated, the close temporal association between the two cannot be ignored. Use of these beverages by individuals with prior psychiatric illness should be with caution and the use of energy drinks may be relevant in the patients' evaluations.
