What's that mental condition where people can't recognize faces?

Question

It's rare, but people who have it cannot recognize their friends and family by their face even though they can see.

Answer 1

Prosopagnosia, or face blindness.

It's actually not that rare; studies suggest that 2% of the population has it. The people who have it don't usually know, because they've adapted other means of recognizing people: hair, clothes, context, etc. They might never realize that others recognize people any differently.

At 34, I just figured out I have a mild case. I asked my parents about it, and sure enough, my mom has it too. She's in her 60s and never realized it.

Answer 2

There's a book that contains some info on it, "The Man Who Mistook His Wife for a Hat." One of the stories is about that problem, I think. There's a part of the brain that regulates your ability to recognize people: proprio receptors, or something like that.

Answer 3

Prosopagnosia

Answer 4

I don't know if it's a mental condition, but is it the same thing as knowing someone name but not picturing who they are? Because if it is I have that problem. Sorry If that doesn't help.

Answer 5

i think is Alzheimer :there are many things the medical community understands about Alzheimer's disease and many things it doesn't yet know. For example, it's not clear why some people with Alzheimer's disease experience faster decline than others. Early Alzheimer's diagnosis and treatment may help to slow progression of Alzheimer's symptoms.



Alzheimer's Disease: Progressing through Three Stages
In people with Alzheimer's disease, changes in the brain may begin 10 to 20 years before any visible signs or symptoms appear. Some regions of the brain may begin to shrink, resulting in memory loss, the first visible sign of Alzheimer's disease.

Over time, Alzheimer's disease progresses through three main stages: mild, moderate, and severe. Because it is not easy to look inside a living brain to see the damage Alzheimer's disease causes, these stages are characterized by a collection of signs and symptoms and behaviors the people with Alzheimer's disease experience.

Mild Alzheimer's Disease
People with mild symptoms of Alzheimer's disease often seem healthy, but they are actually having trouble making sense of the world around them. It often takes time for an observer to realize that something is wrong because the initial symptoms are often confused with changes that take place in normal aging. Symptoms and early signs of Alzheimer's disease may include:

Difficulty learning and remembering new information
Difficulty managing finances, planning meals, taking medication on schedule
Depression symptoms (sadness, decreased interest in usual activities, loss of energy)
Still able to do most activities such as driving a car
Gets lost going to familiar places


Moderate Alzheimer's Disease
In moderate Alzheimer's disease, the damaging processes occurring in the brain worsen and spread to other areas that control language, reasoning, sensory processing, and thought. In this stage, symptoms and signs of Alzheimer's disease become more pronounced and behavioral problems may become more obvious. Signs and symptoms of moderate Alzheimer's disease may include:

Forgetting old facts
Continually repeats stories and/or asks the same questions over and over Makes up stories to fill gaps Difficulty performing tasks
Following written notes Using the shower and toilet Agitation, behavioral symptoms common
Restlessness, repetitive movements Wandering Paranoia, delusions, hallucinations Deficits in intellect and reasoning Lack of concern for appearance, hygiene, and sleep become more noticeable To learn more about slowing the progression of Alzheimer's with Namenda, along with additional Alzheimer's resources, click on the link that best describes your current Alzheimer's treatment situation.

In the advanced stage of Alzheimer's disease, damage to the brain's nerve cells is widespread. At this point, full–time care is typically required. For friends, family, and Alzheimer's caregivers, this can be the most difficult stage. People with severe Alzheimer's disease may have difficulty walking, and they often suffer complications from other illnesses, such as pneumonia. Signs of severe Alzheimer's disease may include:

May groan, scream, mumble, or speak gibberish Behavioral symptoms common
Refuses to eat Inappropriately cries out Failure to recognize family or faces Difficulty with all essential activities of daily living People with moderate to severe Alzheimer's disease may benefit from treatment with Namenda (memantine HCl), the first and only Alzheimer's medication approved to treat moderate to severe Alzheimer's disease. Namenda works in an entirely different way than currently available medications, and offers an important advance in the treatment of Alzheimer's disease.
