On Dec. 25, the Tensia page, which is a page for doctors who provide health knowledge published the story of a medical case study of a 73-year-old woman who experienced the condition of “seeing a face but not knowing who it was” despite being able to remember events, dates, times, and other details. In everyday life as normal
According to the information stated The patient used to live a simple life. Get to know people in the community very well About 2 years ago, he was diagnosed with ischemic stroke, which affected the right occipital lobe of the brain. Even though they made it through the crisis without paralysis or speech problems, But there was a vision problem. Part of the visual field disappeared, which gradually improved over time.
However, after that, the patient began to experience repeated abnormal events. Especially when meeting people. she can hear I felt familiar and remembered the name, but when I looked at the face I couldn’t identify who it was. Even if they are neighbors, relatives, or people who have known each other for decades. The patient described the feeling that “You look like a stranger. But it sounds like someone I know.”
The symptoms did not improve even after more than a year. This causes patients to worry that they may have dementia. Therefore received additional treatment at the hospital. The results of the examination found that the level of consciousness Language perception, general memory, and brain screening (MMSE) scores were within normal limits. There was no weakness or other neurological abnormalities.
Doctors then performed specialized facial recognition tests. Using photographs of famous people It was found that the patients were able to distinguish gender and estimate age correctly. But most of those people cannot be named. Even if it is a person who has been seen repeatedly in the media. for many years
An MRI of the brain revealed signs of chronic brain ischemia in the back of the right side of the brain. in the posterior cerebral artery (PCA) area, spreading to the occipitotemporal region, which is the location of the fusiform face area (FFA), the facial recognition processing center
The doctor therefore concluded the diagnosis: The patient has a condition Prosopagnosia or “blindness of only faces” which is not the loss of vision or memory loss. But it is a disorder in which the brain is unable to associate facial images with the person’s identity and memories.
In this regard, the doctor has given his thoughts from the said case. Facial recognition is a unique skill of the brain. It is not part of normal memory. And even though cerebrovascular disease does not always cause paralysis, But it can have a profound impact on living in society. that those around you may not understand while emphasizing that the brain works as a network and only one point of damage It may change a patient’s view of the world for the rest of their life.
