What cognitive symptom is associated with agnosia?

Agnosia refers to a deficit in the ability to recognize and identify objects, people, sounds, shapes, or smells despite having the ability to perceive them. This condition typically occurs following brain injury, such as after a stroke or in degenerative diseases like Alzheimer's.

The symptoms associated with agnosia are primarily characterized by the loss of the ability to recognize familiar items or features. For instance, an individual may be able to see an apple but might not be able to identify it as an apple, even though their eyesight is intact. This is why the inability to recognize objects and people accurately describes the cognitive symptom associated with agnosia.

In contrast, the other options refer to different cognitive or linguistic challenges. Loss of memory recall relates to amnesia, difficulty in speech pertains to aphasia, and difficulty in abstract thinking does not specifically link to agnosia but may arise from other cognitive impairments related to conditions such as dementia or brain injury. Therefore, the characteristic feature of agnosia is specifically the inability to recognize objects and people, making it the correct answer.
