Table 3.

Hypothetical correlation between PART and AD. From [253].

	No AD/no PART	Asymptomatic PART	p-preAD	NFT-predominant dementia (symptomatic PART)	Symptomatic AD
Aβ phase	0	0–2	1–5	0–2	3–5
Braak-NFT-stage	0	I–IV	0–VI	III, IV	III–VI
Degree of AD pathology	No AD	No or low AD	Low–high AD	No AD or low	Intermediate–high AD
Clinical signs of dementia or cognitive decline	No	No	No	Yes	Yes

PART vs. AD: symptomatic PART and symptomatic AD can be distinguished by Aβ pathology. Asymptomatic PART and p-pre-AD overlap in those cases with initial Aβ pathology (Aβ phases 1, 2)
