Final answer:
Alzheimer's disease has a genetic basis, leading to cognitive decline, but risk can be managed through environmental and nutritional factors. Virtual reality in cognitive rehabilitation offers hope for symptom management. Maintaining an active lifestyle with social connections and access to healthcare information are key aspects of healthy aging.
Step-by-step explanation:
Alzheimer's disease has a genetic basis and is characterized by the formation of plaques in the brain due to cell death. This leads to severe forgetfulness and a decline in various cognitive functions such as walking, talking, and eating. The literature indicates that there are environmental and nutritional factors that can influence the risk and progression of Alzheimer's disease.
For instance, exposure to metals like lead, iron, and zinc can increase risk, while a Mediterranean diet may lower it. Alzheimer's disease is more prevalent among older individuals, nearly half of whom over the age of 85 may exhibit at least mild cognitive impairment. While there is currently no cure for Alzheimer's, strategies like cognitive rehabilitation, which may involve the use of virtual reality, can help manage symptoms and improve quality of life.
Healthy aging involves factors such as staying active, maintaining social connectedness, and recognizing the role of culture and spirituality. Work and family life contribute significantly to a person's sense of meaning, which is crucial for psychosocial well-being throughout the lifespan.
Yet, in late adulthood, there is an inevitable decline in physical ability and a higher risk of developing diseases, including Alzheimer's. Societal trends that emphasize exercise, nutrition, and access to healthcare information are contributing factors that help older adults maintain healthier lifestyles into their later years.
