Table 1

Difference between AD and PD.

	Clinical clues	Classic pathological features
AD	Learning and memory difficulties	Amyloid beta-protein
	Frontal executive function	Neurofibrillary tangles
	Language abilities
PD	Rest tremor	Degeneration of dopamine neurons
	Bradykinesia	Lewy body (LB)
	Rigidity
	Gait impairment
