There are many different theories about what causes Alzheimer's, and that it is not just one problem that starts the disease, but a series of problems. Brain cell damage or loss of brain density can lead to memory and learning impairment. Alzheimer patients can have cognitive and/or behavioral symptoms. Cognitive symptoms affect language, memory, judgment, planning, and ability to stay focused. Behavioral symptoms affect the way we act and feel.

__**Chemical Causes of Alzheimer's**__ Acetylcholine decrease in Alzheimer's patients has been linked to memory loss. Acetylcholine levels in Alzheimer's patients decrease by about 90% from normal levels. Acetylcholine is one of the several neurotransmitters in the brain, along with serotonine and norepinephrine. Other neurotransmitters have also been lower than normal in Alzheimer patients, neurotransmitters serotonin, somatostatin, and noradreneline. The decrease in the chemicals contributes to depression, sleeping disorders, aggressive behavior, and neuron death.

The detection of the protein //beta amyloid// in the brain causes the body's immune system to attack it. The inflammatory response afterwards cause nerves in the area to be damaged.

It has been discovered that aluminum deposits may be linked to Alzheimer's. Researchers have found traces of aluminum in autopsies of Alzheimer's patients, but only some Alzheimer's patients. Many other studies have not been able to prove that aluminum deposits in the brain have lead to the development of Alzheimer's. Scientists do not know whether the ingestion or exposure to aluminum effects the development of Alzheimer's. Food toxins have also been suspect to the cause of Alzheimer's. In Canada, there was an outbreak of a brain disorder with symptoms like Alzheimer's because of an acid the people had ingested, called demoic acid.

The theory is that if a person's immune system breaks down, it can attack the body's own tissue. If the immune system attacks the brain it could cause Alzheimer's disease.
