Dementia is a condition that impairs the brain’s ability to function normally. Several causes can be linked to the condition. Strokes, brain tumors, head injuries, and natural deterioration of mental capacities over time can all result in dementia.
Alzheimer is caused by plaques and tangles in the brain. These will interrupt normal cognitive functioning and result in the above mentioned symptoms. The disease progresses because there is an increase in plaques and tangles.
Currently, more than 5 million people suffer from Alzheimer’s disease in the United States. Approximately 12.5% of Americans older than 65 are at risk for Alzheimer’s, and that figure jumps to a staggering 50% for those over 85.
