What does agnosia refer to in neurological terms?

• A. Inability to perform motor functions
• B. Inability to recognize familiar objects
• C. Inability to speak
• D. Inability to walk

Answer: (B)

Agnosia specifically refers to the inability to recognize familiar objects, people, sounds, or shapes despite having intact sensory functioning. This condition arises from damage to certain areas of the brain, often linked to the visual or auditory processing regions. Individuals with agnosia can see or hear stimuli but cannot interpret or understand them, which highlights the difference between sensory perception and cognitive recognition. The other options describe different neurological deficits: the inabilities to perform motor functions pertains to motor planning disorders; the inability to speak relates to aphasia, which affects language processing; and the inability to walk is classified as ataxia or gait disorders. These conditions encompass a range of neurological impairments not directly associated with the recognition issues characteristic of agnosia.
