Aging is characterized by a progressive loss of physiological integrity, leading to impaired function and increased vulnerability to death. The hallmarks of aging are the types of biochemical changes that occur in all organisms that experience biological aging and lead to a progressive loss of physiological integrity, impaired function and, eventually, death.
The mitochondrial-derived peptide, humanin has been shown to protect against Alzheimer's disease, which is considered an age-associated disease. [ 16 ] MOTS-c has been shown to prevent age-associated insulin resistance , the main cause of type 2 diabetes.

There are numerous diseases for which causes are not known. There are others for which the etiology is fully or partially understood, but for which effective treatments are not yet available. Idiopathic is a descriptive term used in medicine to denote diseases with an unknown cause or mechanism of apparent spontaneous origin. [10]
In 2000, approximately 32% of U.S. adults had metabolic syndrome. [69] [70] In more recent years that figure has climbed to 34%. [70] [71] In young children, there is no consensus on how to measure metabolic syndrome since age-specific cut points and reference values that would indicate "high risk" have not been well established. [72]
About 3% of people between the ages of 65 and 74, 19% of those between 75 and 84, and nearly half of those over 85 years old have dementia. [51] The spectrum ranges from mild cognitive impairment to the neurodegenerative diseases of Alzheimer's disease, cerebrovascular disease, Parkinson's disease and Lou Gehrig's disease.
