This is a 5 day old infant in the alert, quiet state.
  • He has spontaneous movements, which have a smooth flowing quality to them and are not excessive, jerky or asymmetric.
  • He seems to be attentive to the environment.
  • He makes attempts to organize and comfort himself by sucking on his fists, which is a favorable behavioral response.
  • When a bright light is directed towards his eyes he has a definite response, which consists of blinking and avoiding the light.
  • With repeated stimulus there is habituation, a diminished response to the stimulus.
  • He responds to sound by quieting and even turning is head and eyes toward the sound.
  • The above observations are the baby equivalent to the adult mental status exam.
This is a 3 weeks old infant.
  • When the exam begins, he has his eyes closed and appears to be in a drowsy state.
  • Within a few seconds he transitions to an awake state and maintains eye opening but his movements are not vigorous.
  • He responds to light and sound and has some habituation.
  • One has to decide if this is just a sleepy baby or if this baby’s mental status is abnormal.
  • His lack of spontaneous facial and extremity movement is abnormal although he has grimace to light so he has reflexive movements.
