The invention is directed to an in vitro method for performing a differential diagnosis of neurodegenerative diseases in a subject, said subject being selected among subjects suffering from Alzheimer's disease, mental depression, dementia with Lewy Body, frontotemporal dementia, and/or vascular dementia. Said method comprises the steps of: (a) determining at least five criteria of said subject, (b) comparing said at least five criteria of said subject with reference values by calculating a global note in relation with each neurodegenerative disease, and (c) determining whether said subject suffers from Alzheimer's disease, mental depression, dementia with Lewy Body, frontotemporal dementia, vascular dementia or mixed dementia.
