Over $200 billion dollars per year is spent on treating Alzheimer's here in the United States. It is more expensive than heart disease, cancer and stroke combined. Between the ages of 65-74 roughly 3% of the population is afflicted, the numbers increase to 19% or 1 in 5 between the ages of 75-84 and 47% or 1 in 2 for those 85 years of age and older. Clearly these number are increasing each year. The number one disease that people fear as they grow older is, you guessed it, Alzheimer's. It is a slow debilitating disease that robs a person of their life. Yet while the conventional medical community only recognizes the disease much later in life when it becomes very evident, it has been shown scientifically to start much earlier in life with subtle changes in a persons memory and cognition. Scientists have noted these changes as early as people in the 40's.
The first scientific research on glucocortoids damaging the brain neurons was done at the Rockefeller University in 1969 by Bruce McEwen. This research clearly showed the part of the brain most affected was the hippocampus, part of the limbic brain dealing with formulating short term memory. After this many studies have been done reaffirming this hypothesis. By the mid 1980's Robert Sapolsky, a neurobiologist from Stanford, and many others began their own experiments and found that this was caused by an energy crisis. That the neurons were not killed at first but became what they termed "endangered". As the next insult of stress came the neurons were then being killed off.
The body has many built in mechanisms to stop this process but they are very expensive as Sapolsky noted and this energy crisis causes Glutamate, an excitatory neurotransmitter, Calcium and free radicals to flood the synapse causing the problem. Therefore the stress response becomes more damaging than the stressor itself. Give the body something to refuel the brain at this point and you can reduce the insult and save the neurons. Ketones is one energy source.
Because today we ingest a ridiculous amount of carbohydrates our bodies are being fueled by glucose. The brain uses 20-25% of our daily energy demands. We can only store about 1,300 - 1,800 kcal of glucose without having to refuel. Prior to the 1960's we as humans predominately used ketones as our fuel source not glucose. The change in the U.S. governments dietary recommendations to switch to a high carb low fat diet is literally killing us from type 2 diabetes, cancer, CVD, Alzheimers, ADD, ADHD, depression, fatigue, high blood pressure and basically ever other disease you can think of.
Besides eating a high amount of carbs or glucose aka sugar causing or exacerbating most diseases it is a dirty fuel causing Reactive Oxygen Species that damage the DNA of cells. ROS better known as free radicals is what prematurely ages us.
Our bodies have the ability to perform neurogenesis, the production of new neurons. In order to do this we need to address our lifestyle habits of fuel burning and replete the brain of these lost amino acid precursors to make new neurons. Amino Acid Therapy has been used for the past 20 years with great success to do this. It is imperative that you work with a skilled practitioner who has this knowledge as you can deplete other pathways in the brain if done incorrectly. Along with the necessary nutritional changes this program is very successful.
