You are an emergency room doctor and a patient comes to you with a variety of symptoms which started four hours prior to their arrival at the hospital.  The patient’s symptoms are as follows as described by the patient:  1) numbness on the left side of the face  similar to the feeling after the use of local anaesthesia at a dentist office,  2) slight numbness in the left hand which is accompanied by slight weakness when compared to the right hand which is experiencing no issues, 3) slightly blurred vision in the left eye, and 4) general weakness of the legs.   Please provide responses to the following questions.   A) Based only on the symptoms described, would you consider the patient’s symptoms as concerning which should be investigated with urgency?  B) What are the potential medical conditions that should be considered during the diagnosis process?  C) What steps would you take to investigate the patient symptoms?  Please include a list of medical investigations, tests, and imaging.   D) Given a situation whereby you are not able to perform any of the required steps, examinations, and tests, and solely based on the description of the symptoms the patient provides, please provide three potential diagnoses in order of the most probable to least probable diagnosis of the three.  Use some words in all caps in your response, but those all-caps words should appear at most 13 times.
