A neurodegenerative disease caused by the loss of neurons in the brain responsible for learning and memory. AD can cause progressive loss of memory, the ability to communicate, time and space orientation and abstract thinking skills.
A progressive degenerative disease of the brain of unknown cause. Alzheimer's disease is characterized by widespread loss of nerve cells, particularly in the outer region of the brain (cerebral cortex), with distinctive neurodegenerative changes (including senile plaques and neurofibrillary tangles) and reduced activity of acetylcholine and other neurotransmitters of the brain. The disease is the most common cause of dementia or progressive deterioration of thought processing and acquired intellectual abilities. Associated symptoms include initial forgetfulness with increasingly severe memory impairment; disorientation and confusion; loss of the ability to recognize familiar people or objects through sensory stimuli (agnosia); and speech disturbances. The disorder may also be characterized by restlessness and agitation; an increasingly impaired ability to conduct purposeful movements; personality disintegration; and symptoms of psychosis, such as the perception of sights, sounds, or other sensations in the absence of external stimuli (hallucinations) and false beliefs of persecution despite evidence to the contrary (paranoid delusions).
a form of senile dementia that affects the elderly. There are many theories about Alzheimer's origins but its cause remains poorly understood. The latest findings point to its promotion by exposure and consumption of aluminum, that exists in our water supply, antiperspirants, aluminum cans and utensils, commercial processed foods, and elsewhere. There is some evidence that silicon can bind aluminum and help prevent the deleterious effects from aluminum consumption.
