Alzheimer's Disease


***** 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 ***** most prevalent forms of ***** d*****orders contributing to as much as 50 to 70 % of all reported c*****es of dementia. Over the years the study of early onset Alzheimer's disease (pre-senile AD) has kind of overshadowed the study of late ***** Alzheimer in elderly group. However the ***** 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 disease. Hence what ***** previously ignored as an inevitable old ***** symptom (senile dementia) is now being properly recognized as an illness. ***** new perspective of AD has resulted in a drastic*****y altered understand*****g and ***** approach towards diagnosis and treatment. Let us study the disease in a little detail by analyzing the *****s and the etiology along with the diagnostic approaches and ***** currently available treatment methods. In the process we will also briefly discuss some o*****r common ***** ***** dementia and how AD can be differentiated from them.

The Alzheimer's *****

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

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

Symptoms of Alzheimer's Disease

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