Full textFour characteristics define the specificities of the Mexican aging process : It high speed, the absence of relationship between an improvement of the economic situation and population aging, a difficult socio-political context and unique health status, in a sense that cohorts aged 60 years or more survived into old age thanks to medical support rather than because of the standards of living. A potential consequence is an increased frailty of the health status expressed in a greater tendency to develop chronic and degenerative diseases. Data was obtained from 4 health surveys in Mexico. We present the prevalence rates for dementia, obesity, diabetes, hypertension and their associated factors. Our results constitute preliminary evidence about the influence of early childhood health and wellbeing on the future emergence of chronic diseases related to the metabolic syndrome. Our results also suggest an association between the metabolic syndrome and dementia's prevalence and nature. The development of cognitive reserve is limited by factors related to malnutrition in childhood and this is reflected in anthropometric markers and this underdevelopment predisposes to cognitive impairment

Full textThe purpose of this project was to gain more knowledge about cognitive control mechanisms underlying deteriorations and fluctuation of sustained attention in schizophrenia and healthy participants. To that end, we combined the use of behavioral, electrophysiological (event-related potentials and functional connectivity) and subjective measures. Our results revealed spared sustained attention in schizophrenia and a distinct patterns of sustained attention changes in schizophrenia. Deteriorations are underlined by a decrease of reactive mode of cognitive control in patients and by a decrease of proactive mode in controls. Our results also highlighted slightly distinct patterns of precursors of lapses in sustained attention in schizophrenia according to the attentional state. Sustained attention changes are associated with resource depletion in patients, whereas in healthy participants, according to attentional state, they could also be caused by disengagement of cognitive control

Full textWith advancing age, the large elastic arteries undergo significant stiffening, resulting in increased central pulse pressure waves that penetrates deeper the cerebral microcirculation and may result in cerebrovascular and neuronal tissue damages, likely contributing to the development of cognitive impairment from vascular injury origin. This is compatible with strong evidence between impaired cerebrovascular structure and function in the brain of patients with vascular dementia or Alzheimer’s disease. In addition, elderly individuals are subjected in their lifetime to multiple vascular risk factors (hypertension, obesity, diabetes, atherosclerosis), all of which are known to be deleterious to the vascular function, are associated with an increase in central pulse pressure and with cognitive decline. Therefore, it is likely that with age, risk factors for vascular diseases may mechanistically promote the propagation of pulse pressure into the cerebrovascular system and reveal prematurely the brain susceptibility to cognitive decline. The present thesis was conducted to study the biomechanical hypothesis of the deleterious role of the pulse pressure in the deterioration of cerebrovascular and cognitive functions, with age and in association with vascular risk factors, by elucidating the cascade of pathological events linking the increase in central pulse pressure to the expression of dementia. To validate our hypothesis, we first studied in mice the impact of the in vivo increase of central pulsatile mechanical stress (achieved by trans-aortic constriction surgery) on the cerebral vasculature, brain tissue and cognitive functions. This stress was also induced in the APP/PS1 transgenic mouse model of Alzheimer's disease. We have shown that cerebral vessels of WT and APP/PS1 mice are vulnerable to the mechanical stress of the increased pulse pressure, which is characterized by a decrease in the vasodilatory response of the pial arteries, a rarefaction of the capillaries due to apoptosis, the incidence of micro-hemorrhages, a rupture of the blood-brain barrier and cerebral hypoperfusion. These cumulative damages to the cerebral microcirculation are associated with brain inflammation and poorer learning and working and spatial memory performances in mice. The Alzheimer's phenotype of APP/PS1 mice was exacerbated in the presence of elevated pulse pressure, as shown by the increase in beta-amyloid deposits, the decreased in endothelial cerebral vasodilatory responses and brain inflammation, which are already present in this model. In a second study, we sought to characterize the cerebrovascular and cognitive functions in the transgenic mouse model LDLR-/-;hApoB100+/+, subjected or not in vivo to a central pulsatile mechanical stress (by trans-aortic constriction surgery). These mice exhibit risk factors for cardiovascular diseases (hypertension and dyslipidemia), develop atherosclerosis and mimic premature central arterial aging (aortic and carotid stiffness, endothelial dysfunction, increased pulse pressure). We reported that LDLR-/-;hApoB100+/+ mice were characterized by structural and functional brain vascular abnormalities, including cerebral hypoperfusion, increased permeability of the blood-brain barrier, endothelial cerebral dysfunction, microhemorrhages, but also cerebral atrophy and the presence of inflammation, senescence and high oxidative stress at the vascular and parenchymal level. In addition, all these alterations, which are mainly vascular, were associated with a decrease in the cognitive performance of mice. Also, these vascular, parenchymal and cognitive changes were exacerbated in the presence of the vascular stress induced by transverse aortic constriction. Altogether, our two studies in mice demonstrated that, in the presence of an increase in pulse pressure, the damages to the micro-cerebrovascular system lead to loss of cerebral homeostasis and to cognitive decline, which are accelerated in a model of dementia or a model of central vascular aging and in presence or vascular risk factors. Our studies highlight the mechanistic demonstration of a continuum between an increase in pulse pressure and vascular cognitive decline.
