Aging has a direct effect on the nervous system, In the central nervous system, aging affects the brain with dementia and Alzheimer's and other brain diseases. Similarly, the peripheral nervous system, which consists of nerves extending from the brain and central nervous system, undergoes degeneration.(1) As such, in the elderly there is a decrease in sensory and motor nerve conduction and amplitude.(2) Extremity pain, tingling, numbness, loss of balance. swallowing problems, are all related to peripheral nerve degeneration In diabetics, there is increased rate of peripheral nerve degeneration.
AGING: LOSS OF NERVE FIBER - DECLINE IN NERVE CONDUCTION VELOCITY.
Structural changes to nerves occur with age, including decreases in amount of nerve fiber. While both myelinated an unmyelinated fibers are both affected, unmyelinated are most sensitive. Furthermore, loss of nerve conduction velocity is contributed by decrease axon diameter and reduced myelination of the nerve.APIGENIN DELAYS THE DEGENERATION OF PERIPHERAL NERVES
According to recent research, apigenin has been shown to protect the degeneration of peripheral nerves with age Much of this protection is due to the reversal of chronic oxidative stress in the peripheral nerves.(3) Major areas of protection by Apigenin:

Aging is a complex consequence of many factors. Cellular age post-translational non-enzymatic protein modifications is considered as critical in this model. Glycation is damaging of protein structures ,via non-enzymatic binding of glucose to protein. Glycation results in damaged proteins which affects functioning inside the cell and outside the cell. Advanced glycation end products (AGEs) are subsequently formed, and trigger oxidative stress and inflammation. Furthermore, inflammation, age-related oxidative stress, as well as decreased levels of NAD+ in the cell all affect proteostasis, a critical factor in longevity.(1,2) An important function of proteostasis is autophagic clearance of damaged and toxic proteins, such as amyloid.
GLYCATION - INTRACELLULAR AGING
With age, there is a buildup of advanced glycation end products (AGEs) in the cell. AGEs create additional oxidative stress and inflammation in the cell. AGEs also reduce cellular proteostasis, which further reduces the cells ability to eliminate AGE complexes through autophagy. The accumulation of AGEs in cardiac and vascular cells, lead to inflammation and fibrosis, causing atherosclerosis and cardiac diseases. (3)
GLYCATION - EXTRACELLULAR AGING
In particular, modifications such as cross-linking of long-lived molecules with slow turnover. In the extracellular matrix (ECM), the cross-linking of molecules such as collagen and elastin, create loss of cellular homeostasis, especially proteostasis. The cross-linking of these long-lived molecules occur through processes such as glycation. Creates an abnormal stiffness and hardening from which cannot be recovered. Stiffness of the ECM contributes to hypertension, rigidity of arteries, atherosclerosis and cancer.(4)
Perhaps most important, these alterations of ECM reduce viability of the cell, reducing longevity. Due to the diminishing amount of functional elastin, it has been suggested that the maximum limit for elastin dependent cardiovascular and respiratory systems is 100-120 years.(5)
ECM aging is also linked to stem-cell aging, and exhaustion of the stem cell supply. (4) Interestingly, older mouse cells transplanted into younger mice, may outlive the maximum lifespan of an organism by three-fold! This exemplifies the importance of the extracellular environment and how stiff ECM affects cellular lifespan.
Further linkage between ECM stiffness and cellular senescence. Which may also be associated with increased fibrosis. FIBROSIS. Is another key aging indicator. Mitochondrial dysfunction also increases in frequency in a aged (stiff) ECM. Skin aging is accelerated by ECM stiffness, which causes increase in breakdown of skin layers.
ATRIAL FIBRILLATION. Advanced glycation endproducts are involved in the pathogenesis of Atrial fibrillation. (6) Suggested modes of treatment include lowering AGE levels and increasing levels of antioxidants.(9)
BOTANICAL EXTRACTS FOR AGING INHIBITION
Apigenin prevents the formation of AGEs by trapping methylglyoxal (MGO), which is a precursor molecule. Through inhibiting MGO, AGEs will not be formed, thereby reducing oxidative stress and inflammation. In turn, this allows for increased proteostasis in the cell.(6)
Sufficient levels of cellular NAD+ are required for anti-aging cellular functions, including proteostasis. (7,8) The principal regular for cellular NAD+ in cells is CD38.
In animal research experiments, berberine reduced glycation levels. (10) In the brain of Alzheimers Disease mice, berberine invoked autophagic clearance of amyloid beta deposits.(11) Also has been shown to reduce the formation of amyloid beta oligomer formation, this is the prior step before amyloid beta fibril formation. (12) When combined with curcumin, there is a synergistic reduction in amyloid beta production.(13)
Research indicates that rosmarinic acid both inhibits glycation and prevents protein aggregation. Both are correlated to aging pathologies.(14).

Excess body weight is associated with many health concerns, and is rapidly becoming the number one health problem worldwide. among the health risks are diabetes, cardiovascular disease, cancer and premature death. (1) Individuals of the obese classification are especially subject to deleterious health implications. Obesity results in:
Visceral Fat - Obesity results in increases of visceral fat. Visceral fat (also known as belly fat) is the fat that accumulates around organs in the abdominal cavity and is linked to serious diseases, including type 2 diabetes. metabolic syndrome and those affecting organ functioning. Significant levels of inflammatory proteins are generated by visceral fat. In fact, inflammation of the liver which precedes HDLF, is mediated by visceral fat inflammatory proteins.(2)
Nonalcoholic fatty liver disease (NAFLD) - Obesity is a significant risk factor in the development of NAFLD. Most noteworthy, is the excessive buildup of triglycerides in the liver which causes metabolic disturbances throughout the body. As a result, fatty acid metabolism becomes impaired, which may lead to fatty acid intermediates which causes insulin resistance and cardiovascular disease.
Adipose Tissue and Aging - White adipose tissue, associated with obesity, is the most affected tissue in aging. As the adipose tissue ages, there is a significant increase in oxidative stress and the generation of inflammatory proteins resulting in chronic low grade inflammation. In turn, this further damages tissue and accelerates aging. (6)

It is known that the activation of FOXO transcription factors promote extreme longevity, which has been demonstrated in research animals as well as in animals such as the multi-cell animal hydra. In human longevity, those with gene variants which activate higher levels of FOXO are also the longest lived with least amounts of illness and disease.
Despite years of research declaring that antioxidants, such as vitamins C and E, promoted longevity, none have been shown to activate the longevity factors FOXO or Nrf2. Rather, potent longevity factor activation has been shown by many plant based flavonoids. (1) Flavonoids are yellow in nature, and the word is derived from the latin flavus, which means yellow.

While we live in an age where people are living longer, an important limiting factor on longevity is the ability of the heart to maintain function. Known causes of death for the oldest people on record (over 110 years old) were recorded as heart failure. Heart failure is due to the gradual loss of cardiomyocytes (heart muscle cells) and the increase in scarring of the heart muscle. The process may take place due to low grade inflammation of the muscle, which progresses with age, or injury (such as a heart attack) which may cause a more sudden loss of heart function. Inflammation in the cardiovascular system is common with the aging process, being the result of hypertension, high blood glucose, trigylcerides, or oxidized VDL cholesterol.

Aging of the brain involves the loss of neurons (hippocapmus shrinkage), loss of synapse integrity between neurons, build-up of toxic amyloid proteins, neuron tangles, defects in blood flow and chronic inflammation. Under normal age progression, these events do not happen over night and may take years before impairments in cognition become noticed.
Ultimate anti-aging strategies for the brain and memory should target the progressive decline of the brain and promote reversal and recovery of some cognition impairments.
Emerging research in the study of herbal ingredients show their tremendous potential use in mitigating the decline in brain function with age.
