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 most natural approach to get enough Vitamin D is through regular sun exposure. Aim for 10 to 30 minutes of midday sunshine many times per week to maintain appropriate blood levels. Those with darker complexion may require a little more.
<h3>
What is Vitamin D ?</h3>
According to the National Institutes of Health, two to three times per week, between five and thirty minutes of unprotected sun exposure to your face, arms, legs, or back between the hours of 10 a.m. and 3 p.m. is sufficient for your body to produce all of the D3 it requires. Vitamin D synthesis can be inhibited by sunscreen.
Your skin tone, age, dietary habits, and the environment in which you reside all have a role. In general, scientists believe that 5 to 15 minutes, or up to 30 minutes if you have dark skin, is approximately right to get the most benefit without endangering your health. If you wear sunscreen, you can spend more time outside and yet receive the same result.
In the continental United States, UV rays are typically highest between 10 a.m. and 4 p.m. (9 a.m. to 3 p.m. standard time). The UV Index predicts each day's UV ray intensity. Avoid overexposing your skin to the sun if your area's UV index is 3 or higher.
