• Occipital lobe

• Frontal lobe

What type of agnosia involves difficulty recognizing familiar faces?

• Prosopagnosia

• Environmental agnosia

• Achromatopsia

• Anosognosia

Which imaging test is primarily used in research centers to show how active different areas of the brain are?

• Positron emission tomography (PET)

What is the primary treatment approach for agnosia?

• Surgery to remove the affected brain area

• Specific medication for agnosia

• Speech and occupational therapy
