"Brain fog" is a term frequently used by individuals with Chronic Fatigue Syndrome (CFS) to describe a range of cognitive difficulties. This phenomenon primarily encompasses impaired memory or concentration. Patients often report challenges with focus and mental clarity, which can manifest as forgetfulness, sluggish thinking, or an inability to process information efficiently. Distinctly, this cognitive impairment is a hallmark symptom of CFS, impacting the patient's daily functionality and quality of life.

The other options presented, while they can be symptoms associated with various conditions, do not specifically encapsulate the essence of what patients refer to as "brain fog." For example, clouding of consciousness refers to a more general state of awareness that can be caused by various issues, but it is not the specific cognitive impairment described as brain fog. Difficulty in physical coordination pertains more to motor skills than to cognitive processing, and sensitivity to light is a sensory issue, not directly linked to cognitive function.
