Alzheimer's Disease


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 ***** ***** 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 population. Approximately 5% of the population above 65 years of age and around 20% ***** the people above 85 years of age are affected by Alzheimer's disease. Hence what ***** previously ignored as an inevitable old age symptom (senile *****) is now being properly recognized as ***** illness. This new perspective of AD h***** resulted in a drastic*****y altered underst*****ing and new approach towards diagnosis and treatment. Let us study the 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 other common ***** of dementia and how AD can be differentiated from them.

The ***** *****

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

The main cause for the dise*****e is the destruction of ***** ***** cells particularly in the cortex region. In the first stage ***** ***** disease the ***** in the cerebral cortex that is associated with memory is affected. Then as the disease progresses other regions in the cerebral cortex also undergo progressive deterioration lead*****g to total impairment of functional and cognitive *****. Though as in any other ********** of dementia syndrome memory loss is one of the chief and ********** problems the effect ***** the d*****ease extends to much more than ***** loss and in most of the ***** ********** is a ***** crippling of the brain functions *****reby affecting the individuals ability ***** relate ***** respond appropriately to the outside world.

Symptoms of Alzheimer's Disease

As discussed ***** Alzheimer's disease is characterized by a wide variety of ***** from memory loss or amnesia, language difficulties, Dyspraxia or ***** in perf*****ming complex tasks to depression and other *****s of psychotic
