Alzheimer's Disease Alzheimer’s Disease (AD) is a progressive degenerative disease of unknown aetiology, as first described by Alois Alzheimer (1907). According to Shoenberg et. al (1987), it is the commonest cause of dementia in the elderly with an incidence ranging from 2.5 to 5 per thousand. Furthermore, this incidence has grown in recent years as a result people generally living longer. The disease is incurable at present but there are drug treatments that delay the symptoms in the early stages.
Alzheimer’s disease (AD) is a progressive and fatal form of dementia, frequently seen in the elderly altering their cognition, thought process and behavior. AD is reported in about half of patients that have a dementia diagnosis; one study states that about 10.3% of the population over 65 years is affected by dementia with an increase to almost 50% over the age of 85. (Beattie, 2002) Alzheimer’s disease is not a normal part of the aging process in humans, but rather found in a group of diseases that affect the brain leading to a decline in mental and physical control. AD when diagnosed has a very slow and gradual course, initially affecting the individual’s short term memory. (Beattie, 2002) Alzheimer’s disease is the 6th leading cause of death, affecting more than five million people in the United States and is also one of the most common forms of dementia.

People who have the Late-onset Alzheimer’s originates from a complicated series of brain changes that occur over a long period of time. Current drug treatments are given to slow down the cognitive damage temporally. Scientist are currently researching that the disease may be triggered by different factors however age is the most known factor . This nerve racking disease called Alzheimer’s also known as AD was discovered in 1906 by Dr Alois Alzheimer a German physician, this was not considered a critical Disease until the 1970s.It all began with a documented case of a woman by the name Of Auguste D in her in fifties who showed signs of a cognitive disorder as it relates to her memory and socializing with her family. She later died and this great physician decided to do an autopsy on her brain, he then noticed a shrinkage in and around the nerve cells of her brain which led significantly to the discovery of this disease.
