Explanation:

Lupus is an autoimmune disease caused when immune cells attack the body's own tissues and organs, leading to chronic inflammation. Some symptoms of lupus include a butterfly-shaped rash that extends from the bridge of the nose over to the cheeks, swelling of the legs, ankles, feet, face or hands (lupus nephritis), body weakening/chronic fatigue, headaches, anemia, etc. Lupus fog, also known as "brain fog", refers to a cognitive impairment experienced by persons who have lupus. This condition (lupus fog) is associated with several psychophysiological symptoms such as concentration and memory problems and confusion.
