There are two types of Alzheimer's-early-onset and late-onset. These risk factors are the reason some diseases run in families. Genetic risk factors are changes or differences in genes that can influence the chance of getting a disease. People’s genes, which are inherited from their biological parents, can affect how likely they are to develop Alzheimer’s disease.
But it may mean you are more likely to develop it. Having a family history of the disease does not mean for sure that you’ll have it, too. Many people worry about developing Alzheimer’s disease, especially if a family member has had it. Many people live into their 90s and beyond without ever developing dementia. However, age is only one risk factor for Alzheimer’s disease.
#WHAT IS CAUSALITY FREE#
These age-related changes include atrophy (shrinking) of certain parts of the brain, inflammation, vascular damage, production of unstable molecules called free radicals, and breakdown of energy production within cells. Scientists are learning how age-related changes in the brain may harm neurons and affect other types of brain cells to contribute to Alzheimer’s damage. About one-third of all people age 85 and older may have Alzheimer's disease. The number of people with Alzheimer’s disease doubles about every 5 years beyond age 65. Older age does not cause Alzheimer’s, but it is the most important known risk factor for the disease. These and other changes affect a person’s ability to remember and think and, eventually, to live independently. It is characterized by changes in the brain-including amyloid plaques and neurofibrillary, or tau, tangles-that result in loss of neurons and their connections. The importance of any one of these factors in increasing or decreasing the risk of Alzheimer's disease may differ from person to person.Īlzheimer's disease is a progressive brain disease. The causes probably include a combination of age-related changes in the brain, along with genetic, environmental, and lifestyle factors. Scientists don't yet fully understand what causes Alzheimer's disease in most people. Health, Environmental, and Lifestyle Factors that May Contribute to Alzheimer's Disease.
