Alzheimer's disease (AD) is characterized neuropathologically by the presence of β-amyloid (Aβ) plaques and tau immunoreactive neuritic plaques, neurofibrillary tangles, and neuropil threads in the cerebral cortex ().Autopsy studies demonstrate that Aβ and tau pathology accumulate in stereotypical spatial patterns, or topographies, over the course of the disease (2, 3). The Stages of Alzheimer's Disease 1. Building upon the original 1984 diagnostic criteria, the National Institute on Aging-Alzheimer's Association (NIA-AA) revised the clinical criteria for the diagnosis of mild cognitive impairment (MCI) and the different stages of dementia due to AD in 2011 6- 8.The use of supportive biomarker evidence (imaging, serum, and CSF) of AD pathology were included to aid in the . Alzheimer's disease (AD) is a neurodegenerative disease that usually starts slowly and progressively worsens. The FTDs differ from Alzheimer's Disease (AD) in clinical presentation and pathology. They do know that most of the time it begins after age . The second stage is characterised by mild cognitive impairment due to Alzheimer's disease, in which additional biomarkers and imaging technology might help to increase the probability of the underlying diagnosis, although the main diagnosis is made clinically and by exclusion of other causes. It has been estimated that the number of patients who suffer from AD will double Alzheimer's disease is a progressive and fatal illness that causes areas of the brain to shrink. We created 16 modules that focus on outpatient care. Stage 7: Lack of Physical Control. Alzheimer's is the most common disease among seniors which is spreading faster. Neuroimaging modalities such as positron emission tomography (PET) and magnetic resonance imaging are routinely used in clinical settings to monitor the alterations in the brain during the course of progression of AD. 11 . A high-resolution quantitative proteomics map of post-translational modifications on multiple isoforms of Tau shows heterogeneity across Alzheimer's disease patients, reflective of disease progression, and identifies critical targets at each stage of disease.

For many years, investigators have been puzzled by the weak to nonexistent correlation between the amount of neuritic plaque pathology in the human brain and the degree of clinical dementia. Alzheimer's disease is the most common cause of dementia — a continuous decline in thinking, behavioral and social skills that affects a person's ability to function independently. Alzheimer's disease is a brain disorder and therefore the symptoms primarily show an effect on changes in the memory pattern.

It incrementally causes deficits in many cognitive domains, such as episodic memory, working memory and language, with some of these deficits observable at the earliest stages of the disease (Brandt & Rich, Reference Brandt, Rich, Baddeley, Wilson and Watts 1998) and accompanied by . Also, with loss of brain mass, there is an enlargement of the ventricles of the brain.The changes in the brain tissue slowly cause cognitive changes in the person.
