As part of training in paediatric neurology I have a year long attachment at the nearby adult neurology unit. We discuss the challenges that adult neurology brings and I recall three patients who made a particular impact on me for a variety of reasons.  The first is a young man who presents with a functional neurological disorder causing him to be unable to walk. I discuss current thinking about functional neurological disorder and the considerable advances that have occurred in this condition.  The second is a lady who suffers a sub-arachnoid haemorrhage late in pregnancy - we discuss this condition.  Finally we talk about another young man who developed a very severe drug reaction to LSD. This was a condition known as neuroleptic malignant syndrome - something which usually complicates treatment with certain anti-psychotic medications.
