Snapshot A 47-year old woman is brought to the emergency department by the local sheriff. She was arrested earlier in the night for trespassing on the lawn of her neighbor. The patient states in an agitated tone that she was not trespassing, and her neighbor "is in love" with her and had asked her to come over that night. The physician obtains the contact information of the patient's neighbor and upon questioning, he states that he does not even know the patient's last name, and she has been bothering him for the last 6 weeks ever since he moved to the neighborhood. The patient is alert and oriented on mental status examination and denies having any auditory or visual hallucinations.
