  3. The patient must exhibit an actual or preferred avoidance of circumstances resembling or associated with the stressor, which was not present before exposure to the stressor.
  4. Either of the following must be present:
    1. Inability to recall, either partially or completely, some important aspects of the period of exposure to the stressor.
    2. Persistent symptoms of increased psychological sensitivity and arousal (not present before exposure to the stressor), shown by any two of the following:
      1. Difficulty in falling or staying asleep.
      2. Irritability or outbursts of anger.
      3. Difficulty in concentrating.
      4. Exaggerated startle response.
  5. Criteria B, C, and D must all be met within 6 months of the stressful event or at the end of a period of stress. (For some purposes, onset delayed more than 6 months can be included, but this should be clearly specified.)
