As a field expert in cognitive neuroscience, I have a deep understanding of various cognitive disorders, one of which is prosopagnosia, commonly known as face blindness. Prosopagnosia is a neurological condition where a person is unable to recognize faces, including those of friends, family, and even themselves. This condition can significantly impact social interactions and daily life, as faces are a primary source of identity and emotion recognition in humans.
There are two main types of prosopagnosia: developmental (congenital) and acquired. Developmental prosopagnosia is present from birth and is thought to be a genetic condition, while acquired prosopagnosia occurs after brain damage and is much rarer. The prevalence of prosopagnosia varies depending on the type and the population being studied.
Developmental Prosopagnosia: Estimating the prevalence of developmental prosopagnosia is challenging due to its subtle nature and the fact that many people with the condition may not be aware they have it. However, some studies suggest that it could affect as many as 2.5% of the population. If we consider the figure mentioned in the provided content, which suggests a prevalence of 2% in the UK, this would indeed translate to approximately 1.5 million people. Even if this figure is an overestimation, a prevalence of just 1% would still indicate that around 600,000 people in the UK alone have the disorder. These numbers highlight that developmental prosopagnosia is not as rare as once thought and may be more common than other well-known conditions like dyslexia.
Acquired Prosopagnosia: Acquired prosopagnosia, on the other hand, is much less common and is typically the result of brain damage or injury. The incidence of this type of prosopagnosia is directly related to the prevalence of brain injuries that affect the areas of the brain responsible for face recognition, such as the fusiform gyrus and the occipital face area. The rarity of this condition is partly due to the fact that not all brain injuries will result in prosopagnosia, and the extent of the damage required to cause it is quite specific.
It's important to note that the actual prevalence of prosopagnosia may be higher than current estimates suggest, as many cases may go undiagnosed or misdiagnosed. The condition is often underreported because individuals with prosopagnosia may develop coping strategies to manage their inability to recognize faces, such as relying on other cues like voice, hair, clothing, or gait. Additionally, the lack of awareness about the condition among the general public and even healthcare professionals can contribute to underdiagnosis.
In conclusion, prosopagnosia is a fascinating and complex condition that affects a significant number of people worldwide. While developmental prosopagnosia appears to be more common, acquired prosopagnosia is rarer but still an important area of study for understanding the neural mechanisms of face recognition. As our understanding of the brain and cognitive disorders improves, so too will our ability to accurately diagnose and support individuals with prosopagnosia.

As explained above, acquired prosopagnosia following brain damage is rare. ... If this figure is correct, there may be 1.5 million people with developmental prosopagnosia in the UK alone. Even if this is an overestimation, a prevalence of just 1% would indicate that 600 000 people have the disorder.
