NERVOUS SYSTEM CHANGES WITH AGING
The Nervous System
As we age, nerves tend to conduct signals more slowly.
This may be so minimal it is barely noticeable. The
nervous system's response to injury is also reduced.
Changes In The Brain With Age
With age, the brain loses neuron cells and others cells
become damaged. There is a loss of neurons in certain
areas that impacts memory function. It adapts by increasing
the number of synapse, the connections between cells,
and by replenishing the branch-like extensions, dendrites
and axons, that carry messages in the brain.
The brain's weight declines with age in specific places.
From ages 30 to 70, the blood flow to our brain decreases
by 15 to 20 percent.
Atrophy of the grey matter, the outer surface of the
brain, is usually moderate; however, a more extensive
loss of cells occurs in older people with dementia.
Changes In Spinal Cord With Age
After about age 60, the number of cells in the spinal
cord begins to decrease, resulting in a decrease in
sensation.
Changes In Nerves With Age
 The
density of the interconnections seems to reduce with
aging, however like th brain, there is a slow continued
growth of the very end connections between nerves. This
suggests a possible re-patterning of the nervous system.
Some brain proteins, including a number of enzymes,
generally declines. Most notable are those that involve
glucose breakdown and a key enzyme in carbon dioxide
detoxification. Abnormal proteins tend to increase with
age.
Aging changes in brain structure and biochemistry
do not necessarily affect our thinking and behavior.
Whilst individual changes vary significantly, some
aspects of our cognitive ability change with age, the
earliest being the ability to retain large amounts of
information over a long period of time. Naming tasks
and abstraction are altered late in life. Basic language
skills and sustained attention are not altered with
aging. After about age 30, personality is stable. Sudden
changes in personality sometimes suggest disease processes.
Maintain
nerve health with nutritional supplements
such as Magnesium, B Vitamins, Kava kava, Folate, EPA
DHA, Calcium. You will find this assists with sleep
problems also.
Alzheimers
Alzheimer's
disease involves many kinds of changes in the brain,
among them a loss of "cholinergic" neurons.
Studies have shown that the Nerve Growth Factor or NGF,
can rejuvenate dying cholinergic neurons.
Nutritional
Supplements have proven effective in delaying the onset
of Alzheimers.
