	Normal		MCI		AD
	Stable	Converter	Stable	Converter	Slow progressor	Fast progressor
Hippocampus	100%	100%	100%	100%	100%	100%
Entorhinal Cortex	93	100	100	100	100	100
Whole Brain	95	87	93	100	90	100
Ventricle	98	93	100	100	94	100
MMSE	29	58	42	67	73	83

LM II (%)	48	82	43	54
CDR			38	81	58	100

Tests are MMSE = Mini Mental State Exam; DRS = Dementia Rating Scale; AVLT = Auditory Verbal Learning Test – delayed recall; LM II (%) = percent retention on logical Memory subtest of the Wechsler Memory Scale –Revised; CDR = Clinical Dementia Rating – sum of boxes.
