Alzheimer's Disease

Introduction

Alzheimer's disease has developed into a major health concern for the elderly population throughout the world. This degenerative brain disorder was first described by Alois Alzheimer in 1907. Today Alzheimer's is one of the most prevalent forms of brain d*****orders contributing to as much ***** 50 to 70 % of all reported cases of dementia. Over the years ***** study of early onset Alzheimer's disease (pre-senile AD) ***** kind ***** overshadowed the study of late ***** Alzheimer in elderly group. However the ***** statistics indicate an increasing susceptibility of the older *****. Approximately 5% ***** the population above 65 years of age and around 20% of the people above 85 years of age are affected by ********** disease. Hence what ***** previously ignored as an inevitable old age symptom (senile *****) is now being properly recognized as an illness. This new perspective of ***** h***** resulted in a drastically altered underst**********g and ***** approach towards diagnosis and treatment. Let us ***** ***** disease in a little det*****il by analyzing the ********** and the etiology along with ***** diagnostic approaches and the currently available treatment methods. In the process we will also briefly discuss some o*****r common forms of dementia and how AD can be differentiated from them.

The Alzheimer's *****

***** is a progressive, degenerative, and irreversible ***** ***** that stifles the normal cognitive and functional abilities of the ***** person. There is a gradual deterioration of the mental faculties, which may ultimately lead to *****tal dysfunction of the brain resulting in the death of ***** patient. In general the progress ***** the disease is very slow and steady and this presents considerable difficulty in early identification of ***** disease. ***** in some patients there is a sudden ********** rapid decline in brain function leading to death in a few years. Since the human brain is very adaptive the onset of Alzheimer's disease may not be obvious and it is only when as much ***** 80% of ***** ***** cells are damaged symptoms are conspicuous. [Bennett, 63]

The main cause for the ***** is the destruction ***** ***** brain cells particularly in the cortex region. In the first stage of the disease ***** region in the cerebral cortex that is associated w*****h memory is affected. Then as the disease *****es other regions ***** the cerebral cortex ***** undergo progressive deterioration ***** to total impairment of functional and cognitive abilities. Though as in any ***** ********** ***** ***** syndrome memory loss is one of the chief ***** noticeable problems the effect of ***** ***** extends to much more than ***** loss and in most of the ***** ***** ***** a *****tal crippling of the brain functions thereby affecting the individuals ability to re***** and respond appropriately to the outside world.

Symptoms of Alzheimer's Dise*****e

As *****ed above Alzheimer's disease is characterized by a wide variety ***** symptoms from memory loss or amnesia, language difficulties, Dyspraxia or difficulties in perform*****g complex tasks to depression and other kinds of psychotic
