Celebrity Photos for Dementia Diagnosis
Facial recognition test will help diagnose dementia
Therefore, this test can be used as a diagnostic. These are the conclusions of a study by American scientists published in the journal Neurology (Naming vs knowing faces in primary progressive aphasia).
Tamar Gefen from the Cognitive Neurology and Alzheimer's Disease Center at the Northwestern University School of Medicine and his colleagues have proposed a completely new test for detecting cognitive disorders. In particular, the researchers became interested in the diagnosis of primary progressive aphasia. This is an early clinical manifestation of dementia, which consists in impaired speech and a decrease in basic cognitive skills. Aphasia is caused by an asymmetric atrophy of the language center of the dominant hemisphere, which can spread to other parts of the brain.
The test proposed by scientists was called the Northwestern University Test for Recognition of Famous Faces (NUFFACE Test). As part of the test, participants were asked to find out and name 20 world–famous people (so in the text - VM) whose black-and-white photos were shown to them.
The figure shows 4 out of 20 pictures of people from the list given in the article. Don't you recognize everyone?
Or urgently to the doctor, or you live in some other world, not the stars and stripes – VM.
The study of scientists involved 30 patients aged about 62 years with primary progressive aphasia and 27 healthy participants of the control group, corresponding by gender and age. In addition to the NUFFACE test, the participants also passed classical cognitive ability tests, as well as an MRI of the brain to measure the thickness of its cortex.
The results showed that the test results in the control group were much higher compared to the experimental group – 96.9 percent of correct photo recognition versus 78.5 percent and 93.4 percent of correctly named celebrity name versus 46.4 percent. An analysis of the MRI results showed that patients with atrophy of both temporal regions are worse at recognizing a person, and patients with atrophy of the left temporal region recognize a person, but have difficulty remembering his name. Participants in the control group also showed higher results during traditional cognitive tests, which makes it possible to classify the NUFFACE test as a diagnostically reliable test for assessing the symptoms of neurodegenerative diseases.
