In, A Purposeful Life is a Healthier Life, Moheb Costanza discusses the risk of developing neurodegenerative diseases, such as Alzheimer's disease, later in life. His review of the literature indicates having a purpose in life reduces the risk of developing these diseases.

What's the meaning?

Purpose in life is regarded as one of six core dimensions of psychological well-being, along with autonomy, environmental mastery, personal growth, positive relationships, and self-acceptance. People are said to have purpose in life when they can describe specific goals and objectives that give them a sense of directedness and meaning.

Costanza points to various studies to support his view of the conclusions he is advancing and offers quotes for our consideration:

"It may be helpful to think about purpose in life in terms of motivation and environmental enrichment," says neurologist Nick Ward of University College London, who uses functional neuroimaging to investigate how reorganization of brain networks in the cerebral cortex support the recovery of arm function in stroke patients.

"People who are more motivated tend to recover better after a stroke," he adds, "and we know very well from animal studies that environmental enrichment enhances neuronal plasticity."

Neurodegenerative diseases are very problematical. If having, or engendering, a purpose is a palliative reducing the risk of developing these diseases, I favor the idea. The problem I have is doing more of what I have identified as a viable purpose for me.
