Alzheimer’s disease destroys cells in the brain, leading to memory loss and cognitive and behavioral problems. This has an adverse impact on work and social life. The symptoms of the disease increase over time, and at its worse, can be fatal. In terms of causes of death in the United States, it stands as the seventh cause. The warning signs and the stages of the disease must be known to all.
• A form of dementia: Besides memory loss, Alzheimer’s disease causes degeneration of the intellectual abilities, causing a disruption to routine life. Of all the dementia cases, Alzheimer’s accounts for nearly 70 percent. Vascular dementia, mixed dementia, and frontotemporal dementia are some of the types of dementia.
• No known cure: By focusing on the symptoms of the disease, the disease can be treated to a great extent. Thus, millions of lives can benefit. Research focuses on ways to treat and prevent the disease. Alzheimer’s Association tracks latest developments.

There are more 100 billion neurons in an adult brain. Each neuron interacts with other neurons to form networks. Some neurons are closely associated with cognitive abilities and memory. Other neurons are associated with the senses of sight, hearing, and smell. Certain muscle movements, too, have corresponding neurons. A large number of brain cells deteriorate and perish in Alzheimer’s disease.
