Description

The structure and function of the brain change as we age in extremely complicated ways. Prior research has demonstrated that, in addition to vascular-related alterations in the white matter, structural brain ageing is linked to substantial and well- defined patterns of Grey Matter (GM) loss, particularly in the frontal and parietal lobes. There have also been reports of functional changes in ageing brains, with changes in connectivity in the Default Mode (DM) network showing the most recurrent impacts. Furthermore significant is the fact that Alzheimer's Disease (AD) and other neurodegenerative disorders are strongly associated with ageing. Alterations in functional connectivity and structural changes are considered as intermediary phenotypes between pathology and symptoms and may be caused by age- related neuropathologies that have diverse effects on cognitive decline trajectories.

To retain a high quality of life as we age, preserving our cognitive faculties is crucial. Although there is a large and diverse body of literature on the use of cognitive measures to evaluate the effects of ageing and age-related neurological disease, the creation of a set of standardised and accessible tests to characterize the profiles associated with healthy cognitive ageing has been recognised as a key direction for future research. It is well known that decreases in specific parts of memory, executive function, information processing speed, and other chosen cognitive functions occur with healthy ageing. Nonetheless, there are significant individual variations in how well seniors can retain their cognitive abilities as they age.

This heterogeneity can be thought of as a continuum ranging from pathological ageing, which is marked by memory and other cognitive ability impairment and frequently results in dementia, to "successful cognitive ageing," which is the ability to maintain high levels of functioning throughout the lifespan. Knowing why some people age cognitively well while others do not may be a crucial first step in creating therapies that will improve the capabilities and quality of life for the rapidly increasing number of elderly people who live in their communities. Age-related changes in the phase relationship between sleep and body core temperature result in a large shift in the timing of the temperature minimum during the main nocturnal sleep period. It is commonly believed that this age-related alteration in the phase angle between sleep and temperature is what causes the sleep maintenance issues that frequently accompany normal ageing. We employed timed exposure to bright light to replicate in healthy young adults a comparable phase relationship between temperature and sleep in order to test this theory. We wanted to know if this manipulation would cause the same fragmented nocturnal sleep frequently seen in people over 65.

Following a baseline night, three days in a row of morning bright light exposure were given to seven young people. When compared to the baseline, bright light exposure caused the fitted temperature minimum to phase advance by 97 minutes. Wakefulness After Initial Sleep Onset (WASO), sleep efficiency, and the number of stage shifts all experienced significant reductions as a result of the phase advance. Nonetheless, the level of sleep disturbance displayed by these respondents was not as severe as that of the majority of senior subjects. The results show that, despite the fact that chronophysiological changes seem to be closely linked to the propensity to wake up early in the morning, they do not fully explain the severity of sleep disturbance that is usually seen in older patients.

Conclusion

Gerontological research has as its fundamental objective the description, justification, and prediction of aging-related changes that are based on intervention. To accomplish this, appropriate psychological assessment methods are required. The Nuremberg Gerontopsychological Inventory is described as a collection of psychological measurements that allow for the sensitive, accurate, and reliable assessment of changes brought on by interventions as people age. The main elements of this inventory are four separate evaluation levels, including standardized performance tests, observer assessments, self-ratings, and personality ratings. All evaluation methods are modified for aged test subjects. There are standard scores available for people aged 55 to 90. Interrelations between the levels of independently applied evaluation are documented and used to relate various aspects of intervention-induced changes. So, measuring psychological performance becomes useful, for example in terms of daily tasks.
