This prediction of multidirectionality in lifespan trajectories has gained ample empirical support.
This article summarizes the proceedings of the Environmental Barriers and Supports to Health, Function and Participation Work Group that was part of the "State of the Science in Aging with Developmental Disabilities: Charting Lifespan Trajectories and Supportive Environments for Healthy Living" symposium.
Potential reasons that could explain the conflicting evidence include biases that affect the study of the association of adiposity and AD, competing risks, reverse causality, and lifespan trajectories of adiposity.
In his studies, he categorizes the mind into two domains – crystallized and fluid intelligence (Gc and Gf, respectively), 8 which have been illustrative in that they display different lifespan trajectories.
Our understanding of the biological and lifestyle factors that modulate life trajectories must also increase and be leveraged towards increasing human health span in step with human lifespan.
But I would not want to have the same measures taken at 90, regardless of my prognosis, as my quality of life would likely already be compromised and my remaining lifespan brief, its trajectory headed in only one direction.
Importantly, exposure to hyperoxia on day 5 did not affect the average lifespan or mortality trajectories of per mutants, demonstrating that hyperoxia sensitivity in these mutants is an age dependent phenotype.
Alterations of neuronal growth trajectory throughout the lifespan are a core pathology in idiopathic autism and in autism caused by dup(15).
The overall goal of this study was to establish the course of volume changes of the neuronal nucleus and soma cytoplasm throughout the lifespan, assuming that an altered trajectory reflects neuronal development and maturation defects.
