AlzheimerвЂ™s disease, the most common dementia diagnosis among older adults.The five most common forms of dementia are: Currently, there are no cures for these diseases. Neurodegenerative disorders result in a progressive and irreversible loss of neurons and brain functioning. Various disorders and factors contribute to the development of dementia. What are the different types of dementia? Rare genetic mutations may cause dementia in a relatively small number of people.ДЄlthough there is no proven prevention, in general, leading a healthy lifestyle may help reduce risk factors that have been associated with these diseases. While research has found that some changes in the brain are linked to certain forms of dementia, in most cases, the underlying causes are unknown. The causes of AlzheimerвЂ™s and related dementias can vary, depending on the types of brain changes that may be taking place.

ItвЂ™s important to consider a personвЂ™s current abilities and to monitor for changes over time that could signal dementia. People with intellectual and developmental disabilities can also develop dementia as they age, and recognizing their symptoms can be particularly difficult.

Signs and symptoms of dementia result when once-healthy neurons, or nerve cells, in the brain stop working, lose connections with other brain cells, and die. What are the signs and symptoms of dementia? A personвЂ™s symptoms can vary depending on the type. There are several different forms of dementia, including AlzheimerвЂ™s disease. Many people live into their 90s and beyond without any signs of dementia. Dementia ranges in severity from the mildest stage, when it is just beginning to affect a person's functioning, to the most severe stage, when the person must depend completely on others for basic activities of living.Дementia is more common as people grow older (about one-third of all people age 85 or older may have some form of dementia) but it is not a normal part of aging. Some people with dementia cannot control their emotions, and their personalities may change. Dementia is the loss of cognitive functioning - thinking, remembering, and reasoning - to such an extent that it interferes with a person's daily life and activities.
