The pathophysiology of dementia of the Alzheimer type is loss of volume of brain tissue as neurons deteriorate and die.
<h3>What is Alzheimer disease?</h3>
Alzheimer disease is a type of disease that affects the brain cells and it's otherwise called a neurosis.
It is a neurodegenerative disease that is characterized by dementia, that is initial memory impairment and cognitive decline.
Pathophysiology of a disease is the pathway that shows how the disease affects the physiology of the body systems.
The pathophysiology of Alzheimer's disease include:
- The beta-amyloid deposition and neurofibrillary tangles lead to loss of synapses and neurons,
- This results in gross atrophy of the affected areas of the brain leading to death of brain cells.
Therefore, the pathophysiology of dementia of the Alzheimer type occurs due to beta-amyloid deposition which leads to loss of volume of brain tissue.

The inability to metabolize glucose may be due to insufficient insulin production or insensitivity of the cells to insulin.
The hormone insulin is part of the endocrine system.
The definition that "Diabetes is a disease affecting the endocrine system" is an example of an operational definition because it just gives a layman description of diabetes.
