History of Present Illness

History is from EMTs who state they were called to a store for a 50-yr-old man who possibly had a stroke. They found him unconscious but breathing normally. After their arrival, the patient awoke but was unable to give coherent responses to questions or commands.
Store employees who saw the patient reported to EMTs that he fell to the ground suddenly from a sitting position, then began drooling, and his arms and legs shook for what seemed to be a long time, but they cannot quantify how long. They state he had not appeared ill before the event.
