cognitive fluctuations

Cognitive fluctuations refer to temporary changes in mental alertness, attention, and thinking abilities, often seen in certain neurological conditions. Someone experiencing these fluctuations might have periods of clarity followed by times of confusion or difficulty concentrating. These changes are usually unpredictable and can vary from moment to moment or day to day. They are common in disorders like dementia with Lewy bodies or other neurodegenerative diseases, and understanding them helps in managing symptoms and planning appropriate care.
