Dementia is also caused by other diseases and conditions. it is characterized by decline in memory , language , problem solving and other cognitive skills that effects a person’s ability to perform everyday activities. This decline occurs because nerve cells (neurons) in parts of the brain involved in cognitive function have been damaged and no longer function normally , In Alzheimer’s neuronal damage eventually affects parts of the brain that enable a person to carry out basic bodily functions such as walking and swallowing . People in the final stages of the disease are bed-bound and required around  the-clock care .Alzheimer’s disease is ultimately fatal.1
