Hi everyone!Today I am covering some common agnosias that I think OTs should know about. These are pretty straight forward to learn but just harder to rememb.. Agnosia is defined as inability to process certain types of sensory stimulation. Depending on the cognitive systems involved, deficits may appear in different functions, for example in the recognition of visual information, in the execution of sensorimotor patterns or in the understanding of language Agnosia is the inability to process sensory information. Often there is a loss of ability to recognize objects, persons, sounds, shapes, or smells while the specific sense is not defective nor is there any significant memory loss.

Prosopagnosia is the inability to recognize familiar faces. Patients can often identify other aspects like gender, hair, emotions.

Agnosia is inability to identify an object using one or more of the senses. Diagnosis is clinical, often including neuropsychologic testing, with brain imaging (eg, CT, MRI) to identify the cause.
