| Popis: | Pathologies that are causative for neurodegenerative disease (ND) are also frequently present in unimpaired, older individuals. In this retrospective study of 1647 autopsied individuals, we report the incidence of 10 pathologies across ND and normal ageing in attempt to clarify which pathological combinations are disease-associated and which are ageing-related. Eight clinically defined groups were examined including unimpaired individuals and those with clinical Alzheimer’s disease, mixed dementia, amyotrophic lateral sclerosis, frontotemporal degeneration, multiple system atrophy, probable Lewy body disease or probable tauopathies. Up to seven pathologies were observed concurrently resulting in a heterogeneous mix of 161 pathological combinations. The presence of multiple additive pathologies associated with older age, increasing disease duration, APOE e4 allele and presence of dementia across the clinical groups. Fifteen to 67 combinations occurred in each group, with the unimpaired group defined by 35 combinations. Most combinations occurred at a |
