The Appalling Effect of Alzheimer's Disease

I was terrified knowing one of the appalling effects of alzheimer's disease. I read it from reliable source, the 'nun study treatment' that this condition if become severe can wreak physical, psychological, and emotional aspects of the patient. These 3 aspects may fuse together that unfortunately cause the patient to inability to function as normal as before. If the patient is incapable to function, so his or her health condition can then be tricky, knowing that the patient of the Alzheimer's disease becomes willfully rejecting to function correctly when he or she is in fact has the capability to do so.
