A patient arrives in clinic. The move very slowly and when they come into your room they look as though they are shuffling their feet and their arms seem to swing less than normal.“Dr, I am getting progressively stiff, am finding it difficult to walk down the stairs. At first I was ignoring it but it is only getting worse.”
Given this scenario what is the likely diagnosis?Parkinson’s Disease
What is the name given to the gait described above?Festinant gaitTrendeleburg gaitThe Pigeon SkankHigh-stepping gait

What are the three types of Parkinson’s disease, and for each give a cause?Pure Parkinsonism
Idiopathic – Parkinson’s diseaseIatrogenicPost-encephalitic
Parkinsonism with extrasMultiple systems atrophy (3-types: MSA-A, -P, -C)Progressive supranuclear palsy

When assessing the patient you notice that they have a tremor.
A Parkinson’s tremor is:a) A resting tremorb) An essential tremorc) Only seen when sleeping

You treat the patient and two years later he returns and is complains of ‘on-off’ effects.What drug would you have prescribed that would have led to this side effect?Levodopa
Name some other side effects of this drug.Anorexia, drowsiness, Hypomania, Psychosis, Sudden onset sleep, Hypotension, Tachycardia, Arrythmias

Your next patient is a 48 year old male by the name of Mike Litoris. His partner states that his memory is getting worse and that he is unable to concentrate. Mr Litoris agrees and says for the past year he has developed involuntary movements of his fingers and toes.
What disease may you suspect in this patient?Huntington’s Chorea

What disease may you suspect in this patient?Huntington’s Chorea
What would DNA analysis in this patient reveal?Expanded trinucelotide repeat (CAG) on chromosome 4 affecting huntington protein
Like the excellent Dr you are you take a fantastic history and it is revealed that his mother also had the disease. What is the inheritance pattern of Huntington’s Disease?Autosomal DominantHe says it is strange however as she was much older when she started to develop symptoms, and indeed they were not as severe when they came on.What characteristic is this genetic disorder displaying?Anticipation

Your next patient comes in and has the eye sign below.
What is the name of this sign?What disease is it indicative of?
What else is Wilson’s Disease known as?Hepatolenticular Disease
What causes it?a) Copper deposits in the basal gangliab) Alpha-synuclein forming eosinophilic intracellular inclusionsc) Kernicterus (hyperbilirubinamia induced neurological damage)
