Define the two disorders and describe the symptoms of each, noting that the two diseases, although LEADING to dementia of one kind or another, have different behavioural effects. The answer will describe the similarities in the cognitive symptoms of each and the differences between them (as well as the OBVIOUS physical differences). The ESSAY will describe the UNDERLYING neuropathology and USE this knowledge to describe the treatment approaches. The essay might describe how some treatments that can be applied to both (e.g. transplantation) may be more effective for one than the other and explain why this is so.
