Healthy aging. Memory and omega-3

Cognitive abilities are critical for functional independence as people age, including whether someone can live independently, manage finances, take medications correctly, and etcetera. Besides, intact cognition is vital to communicate effectively (processing and integrating information and responding appropriately to others). Cognitive abilities often decline with age, and memory is one of the cognitive functions that deteriorate most. The types of memory most affected by aging are working memory (the short-term memory maintenance and simultaneous management of information), and episodic memory (memory for personally experienced past events). Age-related decline in cognition depends not only upon degeneration in brain structure and function, but also on dietary intake and nutritional status.
Data suggest that certain nutrients may slow or prevent aspects of age-related cognitive decline by influencing some age-related changes in brain structure. Many studies have shown that omega-3 fatty acids have protective effects on the aging brain: they contribute to neuronal membrane structural integrity, control inflammation and oxidation, and promote energy metabolism.
Diets high in omega-3 and omega-6 fatty acids may slow age-related decline in memory promoting, among other actions, white matter integrity.

Diabetes, memory and omega-3

Currently, a diabetic person is fully able to live a normal active life, but he/she must control him/her condition. For example, poorly controlled diabetes can cause memory loss. W[...]
