Study type | Observational |
The aging process tends to promote an overall increase in inflammation compromising the immunologic system regulation, sleep/wakefulness pattern, and neurocognitive performance. In elders, there is an increase in repetitive arousals during sleep, secondary to breathing interruption by pharynx collapse, generating a transient reduction in oxygen delivery to the brain known as obstructive sleep apnea. This lack in oxygen supply results in an inflammatory process producing brain damage. Some substances present in the blood seem to be associated to neurocognitive damage, like S100β protein, cortisol, interleukin 1-β,6 and TNF-α. In the other way, a substance called brain-derived neurotrophic factor (BDNF) enhances cognitive function, and memory consolidation improvement.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Serum level of Brain derived neurotrophic factor | Serum of brain-derived neurotrophic factor will be analyzed in the plasma of elderly volunteers using the Sandwich ELISA method. | Baseline | |
Secondary | Serum level of s100B protein | Serum of s100B protein will be analyzed in plasma in elderly volunteers using ELISA method. | Baseline | |
Secondary | Inflammatory markers | The serum levels of cytokines (IL-1b, IL-6, IL-10 and TNF-alpha) will be analyzed in the plasma of elderly volunteers. The serum level of cytokines using a unit multiplex assay in pg/mL. | Baseline | |
Secondary | Serum Cortisol levels | Serum cortisol levels will be analyzed in the plasma of elderly volunteers. The serum level of cortisol will be quantified by chemiluminescence microparticle immunoassay (CMIA) with reference values for blood collection performed in the morning shift from 3.7 to 19.4 ug / dL. | Baseline | |
Secondary | Neurocognitive Damage | Neurocognitive damage will be measured by the Mini Mental State Examination adapted for the Brazilian population. The maximum score for this scale is 30 points, indicating better cognitive performance. A score of 0-9 points indicates severe cognitive loss; 10-20 points of moderate cognitive loss; 21-26 points mild cognitive loss, 27-30 points without cognitive loss. | Baseline | |
Secondary | Depression | Depression will be measured by the Beck Depression Inventory. A score of 0-9 points indicates that the individual is not depressed; 10-18 points mild depression; 19-29 points moderate depression; 30-36 points severe depression. | Baseline | |
Secondary | Quality of life Score | Quality of life will be measured using the World Health Organization's Quality of Life questionnaire, which has assessments in the domains: physical, psychological, social relations and the environment. The evaluation of each domain is expressed as a percentage, where the higher the result (100%) indicates the better quality of life in the respective domain. The general quality of life is given by the average of the scores of the four domains, whose scores vary from 0 to 5 points. 1-2.9 points the quality of life needs to improve; 3-3.9 regular quality of life; 4-4.9 good quality of life; 5 very good quality of life. | Baseline |
