Previously, aging was associated with predictable memory loss. 49,49,50 Normal aging assumed an inevitably loss of neural capabilities, which led to the uncontrollable loss of independent function in daily life skills. Today, there is growing evidence that neuronal networks continue to grow throughout life.44,45,46 The neuronal network consists of neurons and dendrites that provide the brain's communication system.

Neuronal plasticity theorizes that the brain has a much greater capacity for plasticity than previously believed. Despite age

• the brain has the capacity to maintain and repair neuronal networks. 47
• Dendrites continue to grow in a protective response to natural cell loss that occurs throughout adulthood. 44

Memory loss associated with dementia and Alzheimer’s disease may be observable in the cognitive domains that include:

The complexity of individual neuronal network is conditioned by early sensory integration. There is a direct link between cognitive reserve built over years of rich life experience and cognitive health in later life. 48,49  Memory loss is far less pronounced in people with healthy lifestyles associated with higher levels of education and individual life experience. 50 These healthy lifestyles include:

Healthy Lifestyles incorporates a combination of all healthy lifestyles factors to enhance
