2Face blindness, also referred to as
prosopagnosia, is a nervous disorder that is
characterized by the person's inability to
acknowledge familiar faces. When watching a face,
people with face blindness generally understand
that they're viewing a face however, they find
it difficult to identify the particular
individuals.

3People suffering from face blindness may have
trouble identifying a loved one or sometimes even
themselves when they look into a mirror. There
are two forms of impaired facial recognition
developmental, estimated to occur in as many as 1
in every 50 people, and acquired, which is a rare
case.

4Individual experiences can vary depending on the
face blindness symptoms. Some people with face
blindness cannot easily identify facial
characteristics they can only see a blurred
image of somebodys face.

5Other people who have face blindness can identify
facial expressions with clarity, but they cannot
associate the faces that they see with known
individuals, like friends, relatives, or even
famous people. This variety is generally known as
associative prosopagnosia.

6- What Causes Face Blindness?
- Face blindness has never been proven to have a
single cause, but scientists believe it is linked
to neuroanatomical defects. The disorder is
typically diagnosed when an individual does not
recognize faces in spite of unimpaired vision,
memory, and intelligence. However, some people
may not realize they are face blind until they
experience significant difficulties in daily life.

7- What Causes Face Blindness?
- One of the most common types of face blindness is
developmental prosopagnosia, also known as
acquired prosopagnosia. This condition is caused
by brain damage, typically to the fusiform gyrus
or occipital cortex, which results in an impaired
ability to recognize familiar faces.

8- What Causes Face Blindness?
- This type of face blindness typically develops
late in life and results from damage sustained
during a stroke or cranial nerve injury, such as
Bell's palsy. Some cases could be due to genetic
abnormalities (familial cases), or events that
occur during fetal development.

9- What Causes Face Blindness?
- Developmental prosopagnosia face blindness can
also be part of the autism spectrum disorders,
which suggests a link between this autosomal
dominant condition and other social cognitive
processes such as the theory of mind (the ability
to attribute mental states to others). There are
some books and several articles available on this
topic. You can also get more information on your
smartphone when you search on Google.

10- There are no formal diagnostic criteria to test
face blindness. The normal diagnosis that is
followed typically begins with an assessment of
the individuals history, and a complete physical
examination. An exam typically involves a range
of tests, such as the Cambridge Face Memory Test
(CFMT).

11- Individuals may be asked to memorize and later
identify faces they have never seen before. They
may also be asked to find similarities between
different faces, or estimate someones age or
facial expression.

12- Physical examination should always involve the
assessment of visual acuity, which measures the
clarity and sharpness of ones vision and memory.
In cases where the patient has acquired
prosopagnosia, further diagnostic testing may be
required in order to identify the actual
underlying causes.

13- There are no specific medical interventions or
face blindness cure therefore, treatment is
aimed at improving recognition abilities.
Learning adaptation techniques, such as trying to
recognize others by remembering identifying
features other than faces, can help some
individuals with face blindness.

14- However, this approach may not always be
practical because some changes to these
attributes can cause confusion for those with the
condition.
