The Journal Of Neuroscience.<\/a> Super-agers are people in their 80s with excellent cognitive and physical functioning.<\/p>\nThe study stated that super-agers have less brain atrophy compared to people in the same age group. Also called cerebral atrophy, brain atrophy is a loss of neurons and connections between neurons.<\/p>\n
This particular study was conducted on 119 octogenarians, including \u201c64 super-agers (mean age 81.9; 59% women) and 55 typical older adults (mean age 82.4; 64% women)\u201d.<\/p>\n
The study added, \u201cWe studied the white matter structure of a large sample of 64 super-agers over the age of 80 and 55 age-matched typical older adults during 5 years with yearly follow-ups showing evidence of slower age-related changes in the brains of super-agers especially in protracted maturation tracts, indicating resistance to age-related changes and a regional ageing pattern in line with the last-in-first-out hypothesis.\u201d<\/p>\n
Each of these participants was asked to complete a variety of tests, which assessed their memory, motor and verbal skills.<\/p>\n
The study noted that while \u201cmemory normally declines with age, some older people may have memory performance similar to that of people 30 years younger.\u201d<\/p>\n
It stated that this phenomenon is \u201cconceptualised as super ageing.\u201d<\/p>\n
The study revealed, \u201cSuper-agers and typical older adults showed no difference in global white matter health (total white matter volume, Fazekas score, and lesions volume) cross-sectionally or longitudinally. However, analyses of diffusion parameters revealed better white matter microstructure in super-agers than in typical older adults.\u201d<\/p>\n
The findings also stated, \u201cCross-sectional differences showed higher fractional anisotropy (FA) in super-agers mostly in frontal fibres and lower mean diffusivity (MD) in most white matter tracts, expressed as an anteroposterior gradient with greater group differences in anterior tracts.\u201d<\/p>\n
The study further noted that the decline of this FA progresses at a slower rate in super-agers compared to the usual aging trajectory observed in older adults. Additionally, researchers found that the white matter microstructure remains more intact in super-agers than in their typical adult counterparts.<\/p>\n
The researchers claimed that understanding the phenotype of any super-ager can detail the \u201cmechanisms of protection against age-related memory loss and dementia.\u201d\u00a0<\/p>\n<\/div>\n
