What is lupus fog?

Lupus fog, also known as cognitive dysfunction or cognitive impairment, is a condition of those individuals with lupus that causes them to experience difficulty in remembering how to perform everyday tasks. Symptoms can start and stop, or last for extended periods of time. The person experiencing lupus fog is generally fully aware it is happening, and as such can experience a high level of stress.

Sometimes, if the lupus has directly affected the brain, it can cause the cognitive malfunction. Most often, however, the fog is a side effect of treatment for lupus.

The term "lupus fog" refers to cognitive dysfunction that may be experienced by those with systemic lupus erythematous (SLE). This may manifest as changes to long-term or short-term memory, abstract thinking, judgment and use of language. This condition may be associated with medications such as steroids, or with small blood clots leading to an accumulation of mini-strokes.
