ABSTRACT
A 75-year-old man has been found on the ground by his neighbour and brought to the emergency department. The man appears unkept, confused and agitated. His only complaint is of numb feet and he appears unsteady. Once a week his neighbour checks on him but generally he likes to be left alone. The neighbour has noticed that the man’s memory has been worsening lately. It is unclear what medications he might be taking, but the neighbour recalls he is a diabetic and takes ‘a tablet’ for this. He is not known to drink alcohol but does smoke. He is known to be a vegetarian.
