What is a nervous system disorder?

1. Arthritis

2. Encephalitis

3. Atherosclerosis

4. Osteoporosis

The correct answer is: Encephalitis

A nervous system disorder refers to any condition that affects the normal functioning of the brain, spinal cord, and nerves throughout the body. Encephalitis specifically is an inflammation of the brain, usually caused by a viral infection, and it directly impacts neurological function. Symptoms may include headaches, fever, confusion, and in severe cases, seizures or loss of consciousness. In contrast, the other listed conditions do not primarily involve the nervous system. Arthritis refers to inflammation of the joints, affecting mobility but not directly impacting the nervous system. Atherosclerosis is related to the buildup of fats in the arteries, affecting blood flow rather than neurology. Osteoporosis involves weakening of the bones, also not a nervous system disorder. Thus, encephalitis is the clear example of a condition that specifically impacts the nervous system.
