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 as 50 to 70 % of all reported c*****es of dementia. Over the years ***** study of early onset Alzheimer's disease (pre-senile AD) has kind of overshadowed the study of late ***** Alzheimer in elderly group. However the disease statistics indicate an increasing susceptibility of the older *****. Approximately 5% of the population above 65 years of age and around 20% ***** the people above 85 years of age are affected by *****'s *****. Hence what ***** previously ignored as an inevitable old age symptom (senile *****) is now being properly recognized as ***** illness. ***** new perspective of ***** h***** resulted in a drastically altered understand*****g and ***** approac***** towards diagnosis and treatment. Let us ***** ***** disease in a little det*****il by analyzing the symptoms and the etiology along with the diagnostic approaches and ***** currently available treatment methods. In the process we will also briefly discuss some other common ***** ***** dementia and how AD can be differentiated from them.

The Alzheimer's *****

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

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

Symptoms of Alzheimer's Disease

As discussed ***** Alzheimer's disease is characterized by a wide variety ***** symptoms from ***** loss or amnesia, language difficulties, Dyspraxia or ***** in performing complex tasks to depression and o*****r kinds of psychotic
