Cognitive Impairment

Meaning

Cognitive Impairment denotes a measurable decline in one or more specific cognitive domains, such as memory, executive function, attention, or processing speed, that falls below the expected level for the individual’s age and education. This decline can range from mild, not interfering significantly with daily activities, to severe dementia. Hormonal imbalances, particularly involving thyroid or sex steroids, frequently contribute to this clinical presentation.
