What is cognitive impairment among older adults?

Senior adults should be aware of the implications of cognitive decline as a result. It can be associated with many age-related disorders and diseases, and it can impact the quality of elderly's lives. As people age, it becomes more crucial to maintain a high-quality of life. It is critical to target and identify the causes of age-related cognitive dysfunction. The biological basis of cognitive decline is still not clear. Studies in animal models are providing insight into the underlying mechanisms. The new study, published in eLife, December 1, 2020, suggests that ISRIB, a drug, can reverse the declines in cognition caused by age.

Aging is characterized by an increase in systemic markers of inflammation. There is a strong correlation between chronic inflammation and cognitive decline. Alzheimer's disease and dementia are both associated with neurodegenerative conditions. This can be controlled by reducing inflammation signaling.

There are several clinical biomarkers that have been found to predict cognitive decline and to predict clinical progression to mild cognitive impairment (MCI). An oral glucose tolerance test can be used to detect glucose homeostasis. Impaired glucose tolerance is associated with an increased risk of MCI, Alzheimer's disease, and dementia. In addition, oxidative stress is a possible link between physical frailty and cognitive decline.

The declines in episodic memory and executive function that are associated with inflammation can also be linked to age-related impairments. Many animal models have shown that cognitive impairment is caused by nonpathological brain inflammation. Neuroinflammation was also linked to rodents (pigeons), humans, and rodents. But, it is unclear if inflammation is the main factor that causes cognitive decline as we age. There may be other contributing factors, such as oxidative stresses and mitochondrial dysfunction.

To determine if someone is at high risk of cognitive decline, neuroimaging and molecular biomarkers were identified. Baseline markers such as CRP and cortisol have been shown to be associated with memory impairment and memory loss. Research has suggested that cognitive decline may be caused by higher cortisol levels. Increased cortisol levels are associated with decreased hippocampal volume among Alzheimer patients. Cortisol is a hormone that the adrenal glands make. Frail older adults might be more vulnerable to stressors due to higher cortisol levels in their cortex.

Glucose tolerance can be used as a screening tool to determine if someone is at high risk for cognitive decline. An oral glucose tolerance test called OGTT-2h can help assess glucose homeostasis. Higher levels of glucose are associated with greater migration. Impaired glucose tolerance was assessed in community-based volunteers who were not diabetic. Participants who showed impaired glucose control due to glucose tolerance were assigned one of three groups: 0.1-0.0.5.0.5. Cognitive migration was worse for those in the 0.5–to-1.5 group. This was determined through measuring the global CDR.

To investigate frailty among older adults, the ELSA-Brazil research was done. A global CDR score was used to screen patients for cognitive performance and physical frailty. It was administered by certified raters. Cognitive performance and impairment were then assessed. As the primary outcome in clinical care, global CDR changes were used.
