3. ALZHEIMER’S DISEASE Alzheimer's is the most common form of dementia . It is a neurodegenerative disease that occurs in the brain. This disease causes deterioration in brain by destroying the nerve cells. Once the nerve cells begin to deteriorate , it causes a reduction of responses to other nerve cells . The condition spreads out causing chemical interruptions , the transmission of impulses is slow ,and the tissues in the brain begin to get worse. The nerve cells in the brain die gradually .This makes it increasingly difficult for your brain signals to be sent properly. There are seven stages of Alzheimer's.

4. CAUSE OF ALZHEIMER’S DISEASE Scientists generally agree that there is unlikely to be a single clear “cause” of Alzheimer's. It is more likely the result of a combination of inter related factors , including genetic factors, which are passed along family lines of inheritance, and environmental influences etc. A growing body of research is also helping to identify various “ lifestyle factors ”which may influence ones risk of Alzheimer's diseases. Alzheimer’s develops as a result of a complex cascade of biological processes that take place over many years inside the brain.

5. SYMPTOMS FOR ALZHEIMER’S DIFFICULTY PERFORMING OTHERWISE FAMILIAR TASKS. MEMORY LOSS THAT AFFECTS JOB SKILLS. PROBLEMS USING LANGUAGE. DISORIENTATION TO TIME AND PLACE. LOSS OF GOOD JUDGEMENT. PROBLEMS WITH ABSTRACT THINKING. MISPLACING THINGS. RAPID MOOD SWINGS. PERSONALITY CHANGES. LOSS OF INITIATIVE,SLEEPING USUAL ,AND LOSS OF INTEREST

6. ALZHEIMER’S DIAGNOSTIC TESTS MEDICAL HISTORY an interview or questionnaire to identify past medical problems. PHYSICAL EXAMINATION includes evaluation of hearing and sight, heart and lungs, as well as temperature , blood pressure and pulse reading NEUROPHYSIOLOGICAL TESTING doctors use variety of tools to access memory , problem solving , attention , vision-motor coordination and abstract thinking ,such as performing simple calculations in your head.

7. BRAIN IMAGING SCAN MRI and CT scans look at the structure of the brain and are used to rule out brain tumors or blood clots in the brain as the reason for the symptoms.

8. TREATMENT FOR ALZHEIMER’S Drugs used to treat Alzheimer's fall in to two broad categories :- Drugs to treat cognitive symptoms , such as memory problems and other mental deficits of Alzheimer's and Drug to treat behavioral symptoms that do not respond to non - pharmacological behavior These drugs might include a variety of types of drugs broadly categorized as anti-agitation drugs.
