Longitudinal periodontometry [PDF]

open access: yesJournal of Periodontal Research, 1971
The O'Leary‐Rudd periodontometry system was modified to facilitate longitudinal studies of horizontal tooth mobility. Repeated measurements of the horizontal tooth mobility of tooth #27 and tooth #28 were accomplished in six patients to determine the accuracy and experimental error of the modified system.

Is Baseline Orthostatic Hypotension Associated With a Decline in Global Cognitive Performance at 4‐Year Follow‐Up? Data From TILDA (The Irish Longitudinal Study on Ageing)

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2018
Background It is postulated that orthostatic hypotension (OH), a reduction in blood pressure (≥20/10 mm Hg) within 3 minutes of standing, may increase cognitive decline because of cerebral hypoperfusion.

Associations between Cardiovascular Signal Entropy and Cognitive Performance over Eight Years

open access: yesEntropy, 2021
In this study, the relationship between non-invasively measured cardiovascular signal entropy and global cognitive performance was explored in a sample of community-dwelling older adults from The Irish Longitudinal Study on Ageing (TILDA), both cross ...

Verbal intelligence is a more robust cross-sectional measure of cognitive reserve than level of education in healthy older adults

open access: yesAlzheimer’s Research & Therapy, 2021
Background Cognitive reserve is most commonly measured using socio-behavioural proxy variables. These variables are easy to collect, have a straightforward interpretation, and are widely associated with reduced risk of dementia and cognitive decline in ...
