Question

Alzheimer's disease is an autoimmune disease.
a) True
b) False

Answer 1

An autoimmune disease is a condition in which your immune system mistakenly attacks your body. An autoimmune disorder may affect a single or various organ or tissue types.

Complete answer:
The immune system of our body normally guards us against germs like bacteria and viruses. When the body senses any foreign invaders, it automatically sends out an army of fighter cells called antibodies to attack them. In many cases, the immune system can tell the difference between foreign cells and your own cells but in an autoimmune disease, the immune system mistakes part of your body, like your joints or skin, as foreign. It releases proteins known as antibodies that attack healthy cells. Psoriasis, vitiligo, and rheumatoid arthritis are all autoimmune diseases.
-Alzheimer's disease
It is generally a progressive disease that destroys memory cells and other important mental functions. Connections in the brain and the cells degenerate themselves slowly and eventually die, destroying memory and other important mental functions.
-Psoriasis/psoriatic arthritis
Normal skin cells grow and then shed when they’re no longer needed. Psoriasis causes skin cells to multiply too quickly than the average time. The extra cells that grow build up and form inflamed red patches, commonly with silver-white scales of plaque on the skin. People with psoriasis may also develop swelling, stiffness, and pain in their joints. This form of the disease is known as psoriatic arthritis.
-Rheumatoid arthritis (RA)
In rheumatoid arthritis (RA), the immune system attacks various joints of the body. This attack may cause redness, soreness, and stiffness in the joints. Unlike osteoarthritis, which commonly affects people as they get older, RA can start as early as your 30s or maybe sooner.
-Vitiligo
A disease causes the loss of skin color in blotches and occurs when pigment-producing cells die or stop functioning.

So, the correct answer is b) False.

Notes:
Researchers don’t know exactly what causes autoimmune disease. Genetics, diet, infections, and exposure to chemicals can be involved. Medication can mainly treat autoimmune diseases by bringing down inflammation and calming the overactive immune response. Treatments can also help relieve symptoms.
