Contemporary debate on human aging is intensive and multifaceted in nature because of agerelated transformation in many contemporary societies, i.e. a rapid increase of mean life expectancy (increasing numbers of healthy old people). The aim of this article is to discuss changes in brain and behavior that occur in later life. Life-span developmental neuropsychology emphasizes a close relationship between cognitive problems in later life and age-related loss of large neurons in some parts of the brain. Large neurons shrink into smaller neuron classes. The most pronounced atrophic changes have been reported in the prefrontal area, hippocampus, ubstantianigra and locus cinereus. This article presents also common clinical conditions of later life, such as differential diagnosis of age-associated behavioral changes and dementias. There may be multiple causes of neurogeriatric disorders, such as Alzheimer’s disease. There has been considerable interest in the possible causative role of cognitive and brain reserve which differs among individuals. Therefore between-individual heterogeneity related to normal cognitive aging is signifi cant. Namely, if cerebral pathology occurs (e.g., neurodegeneration with dementia), persons with a greater reserve may not demonstrate the same cognitive impact as others with the same pathology (e.g. lesion size) but less reserve. It is also widely believed that mental difficulties in lder adults cannot be easily attributed to psychomotor slowness which may reflect a loss of white matter tissue, i.e. dysmielinisation of nerve fibers. This article emphasizes an importance of ecologically valid assessment of older adults, whose everyday activities and real--world abilities cannot be predicted by the traditional tests and sophisticated procedures emerging from purely experimental investigations.

Old age is characterized by an age-related cognitive decline. The role of executive functions in this process has recently been indicated. The population of elderly people, however, is not homogenous in terms of intellectual functioning. This diversity may be explained by evoking the notion of cognitive reserve which posits that elderly people have different levels of resources enabling them to compensate for the negative changes. The level of the cognitive reserve is related to the level of the executive functions. This study analyzes the relationship between the levels of three components of the executive functions: flexibility, working memory and planning, and educational, cultural or physical activities carried out throughout life. The results show that educational and cultural activities are important to working memory, while planning is additionally helped by physical activity. Further, some components of the executive functions are more infl uenced by activity before retirement, while others are more affected by activity after retirement.

Predictions for the upcoming decades suggest an increase in the number of elderly people in Europe; due to low fertility and the rise in average life expectancy, societies age considerably faster. The nature of these changes signifies that a complex demographic process is taking place. In consequence, one can notice an increase in the demand for personal and nursing care activities provided in the natural human environment, or in various institutions, by adequately prepared, specialized medical staff. Creating the best possible procedures for assisting elderly people is a multifaceted and dynamic problem. The constantly changing expectations regarding healthcare providers, and the higher social and health awareness are challenging medical sciences and social services to provide the oldest generation with the best quality of life. The life satisfaction measure for elderly people is their activity which determines an independent, self-reliant, satisfactory, and long life.

The concept of cognitive reserve (CR) refers to the situation when the brain pathology does not correspond to clinical symptoms, i.e. they are absent or weakened in combination with the established clinical diagnosis and/or the prediction of cognitive deficits (e.g. in the aging process). The article discusses the definition of cognitive reserve, methods of its measurement, brain mechanisms of CR, the role of CR in the process of successful aging, debatable issues and reference of the idea of CR to clinical practice.
PL
Koncepcja rezerwy poznawczej (cognitive reserve – CR) odnosi się do sytuacji, w której patologia mózgu nie koresponduje z objawami klinicznymi, tj. są one nieobecne lub słabo nasilone w zestawieniu z postawionym rozpoznaniem klinicznym i/lub przewidywaniem deficytów poznawczych (np. w procesie starzenia się). W artykule omówiono definicję rezerwy poznawczej, sposoby jej pomiaru, mózgowe mechanizmy CR, rolę CR w procesie satysfakcjonującego starzenia się i kwestie dyskusyjne oraz odniesiono ideę CR do praktyki klinicznej.
