What term describes the loss of the ability to think logically and clearly?

The term that describes the loss of the ability to think logically and clearly is cognitive impairment. Cognitive impairment encompasses a range of conditions that affect memory, thinking, and social abilities, which are significant enough to interfere with daily life. This term encapsulates issues with processes such as reasoning, judgment, and the capacity to understand and relate to the environment effectively.

Memory loss specifically refers to challenges in recalling information, which is just one aspect of cognitive function and does not fully encompass the broader inability to think clearly or logically. Psycho-emotional decline refers more to emotional aspects and psychiatric conditions rather than the cognitive processes in question. Behavioral issues typically relate to actions or conduct rather than the underlying cognitive abilities affecting thought clarity and logic. Therefore, cognitive impairment is the most accurate term to describe the overall decline in logical and clear thinking.
