78-year-old man, without significant past medical - abrahem

[ArchivalUser]

78-year-old man, without significant past medical history and taking no regular medications, has become increasingly forgetful over the last 18 months, to the point where he now finds it difficult to remember the names of some members of his family. He has recently been having visual hallucinations. On examination he seems rather expressionless and has cogwheel rigidity of both arms. The most likely diagnosis is:
A : Alzheimer™s disease
B : Lewy body dementia
C : Vascular dementia
D : Frontal lobe dementia
E : Alzheimer™s disease and Parkinson™s disease.
