ABSTRACT
A 33-year-old gentleman was brought to the emergency department by his co-workers, who reported a decline in his cognitive function. His manager stated that the patient had initially become emotionally labile several weeks earlier but had more recently developed short-term memory loss and poor co-ordination, frequently tripping over and stumbling when walking, and spilling drinks. The patient denied any symptoms and said he had only consented to come to hospital because he had been escorted by several team members. He said his colleagues were ‘going mad’ and ‘imagining things’. He had no past medical history and did not take any regular medications. He did not smoke, was unclear regarding alcohol intake (‘it's none of your business’) and denied any recent travel or recreational drug use.
