Prosopagnosia: Face Blindness
While everyone has occasional difficulty recognizing others, people with prosopagnosia
experience this problem to a much greater extent. Prosopagnosia, a term derived from
the Greek words for "face" and "lack of knowledge," refers to a neurological disorder that
impairs a person's ability to recognize faces. People with severe cases of the disorder may
even have difficulty recognizing their own family members. The current understanding of
prosopagnosia is quite limited, although the condition is thought to be related to a
problem in a fold of the brain called the right fusiform gyrus. By conducting research on
people with face blindness, neuroscientists hope to learn more about its causes and
develop possible treatments. For now, people who are face blind must rely on alternative
techniques to identify others. They may recognize people by their voices, clothing, or
hairstyles, or they may infer someone's identity because they routinely encounter the
individual in a particular setting.
What is the main idea of the passage?

Prosopagnosia is a sometimes severe disorder that causes people to have
difficulty recognizing faces.

People with prosopagnosia may rely on voices and visual cues to help them recognize others.

Prosopagnosia research is limited but will hopefully lead to the development
of future remedies.
