Actor Brad Pitt revealed in a recent interview that he suffers from prosopagnosia, a rare neurological disorder also known as “facial blindness.”
Dani Blum describes the disorder’s signs, causes, and remedies in an article for the New York Times.
Borna Bonakdarpour, a behavioral neurologist at Northwestern Medicine, claims that face blindness—not color blindness or general vision impairment—is the main symptom of prosopagnosia.
The National Institute of Neurological Disorders and Stroke states that there is no connection between the illness and memory loss, vision problems, or learning impairments.
Blum continues, “It is not the same as forgetting or occasionally having trouble finding the correct word.
The severity of prosopagnosia will differ from person to person.
For instance, some people might have problems identifying a familiar face, such as that of a close friend or relative, while others might have trouble identifying their own reflection.
Additionally, some people might not be able to distinguish between faces and objects.
Notably, some data indicates that individuals with prosopagnosia may have chronic anxiety or depression due to the loneliness and fear that are frequently associated with the illness.
Blum notes that some people avoid contact with family members and other loved ones out of concern that they won’t be able to properly recognize or acknowledge them.
“Navigating basic social relationships with prosopagnosia can become difficult,” she says.
Pitt admitted that he has trouble recognizing people’s faces for years in a recent interview with GQ, despite never having gotten a formal prosopagnosia diagnosis.
In fact, Pitt claimed in a 2013 interview with Esquire that his difficulty recognizing people’s appearances was so great that it frequently made him want to isolate himself.
He explained, “That’s why I stay at home.
What is the condition’s cause?
People who are diagnosed with prosopagnosia often fall into one of two categories: either they are born with it or they acquire it.
However, estimations reveal that as many as one in every 50 people may struggle with some lifetime form of the disorder, and experts hypothesize that it may run in families.
According to Blum, research “suggests that congenital, or lifelong, prosopagnosia is less prevalent.”
According to Andrey Stojic, director of general neurology at the Cleveland Clinic, children born with the illness “don’t seem to have any visible structural abnormality” in the brain.
Notably, doctors don’t fully understand what causes congenital prosopagnosia because there aren’t any obvious brain lesions in persons who have it.
In contrast, people who develop prosopagnosia later in life may have brain abnormalities brought on by a trauma or head injury.
According to Bonakdarpour, individuals can also develop prosopagnosia while dealing with Alzheimer’s illness or following a stroke.
What therapies are available for prosopagnosia?
Prosopagnosia is now untreatable, according to Bonakdarpour. The problem can be treated, though.
People who have the syndrome frequently attempt to distinguish between people by focusing on physical characteristics like hair color, gait, or voice.
Spe:rm Cells Carry Traces of Stress Experienced by the Father, New Study Shows
Can stress be passed down from one generation to the next? A groundbreaking study suggests that it can—at least in a way we never imagined before. Researchers have discovered that sperm cells can carry traces of stress experienced by the father, which may impact the health and stress response of future offspring.
This revelation challenges long-held beliefs about inheritance and genetics. Traditionally, we’ve assumed that only genetic sequences are passed down, but this study shows that environmental factors like stress can leave biological imprints on sperm. The implications? A father’s emotional and psychological well-being before conception could shape the mental and physical health of his children.
Let’s dive into what this means, how stress alters sperm cells, and what it could mean for future generations.
The Study: What Scientists Discovered
A team of researchers set out to explore how stress affects sperm and whether those changes could be passed to offspring. The study, conducted using animal models, found that sperm cells carry epigenetic markers influenced by stress levels prior to conception.
Epigenetics refers to changes in gene expression that do not alter the DNA sequence itself but can still be inherited. These changes act like biological “notes” added to genetic material, influencing how genes behave in offspring.
One of the most startling findings? The stress experienced by a father before conception may increase the likelihood of mental health disorders in his children. Anxiety, depression, and stress-related disorders could all be linked to epigenetic changes in sperm.
How Stress Affects Sperm Cells
The study uncovered specific biological mechanisms through which stress alters sperm. One of the primary processes involved is DNA methylation—a chemical modification that regulates gene activity.

Here’s what happens:
- When a male experiences chronic stress, his body releases stress hormones like cortisol.
- These stress signals trigger epigenetic modifications in sperm, particularly in the form of DNA methylation.
- Once the sperm carries these changes, they can influence gene expression in the offspring, altering their stress response and overall health.
What does this mean in practical terms? Children of stressed fathers may have an increased sensitivity to stress, making them more prone to anxiety, depression, and other psychological conditions.
The Bigger Picture: Implications for Human Health
Although this study was conducted using animal models, the findings have far-reaching implications for human health. Traditionally, research on reproductive health has focused primarily on maternal factors, such as a mother’s diet, stress levels, and overall health during pregnancy.
This new research suggests we need to expand our focus to include paternal health. A father’s emotional and psychological well-being before conception could play a critical role in determining a child’s future health.
Some key takeaways:
- Stress is not just a personal burden—it may have consequences for future generations.
- Men’s health, both physical and mental, is an essential factor in reproductive success.
- Healthcare approaches should address both maternal and paternal stress levels before conception.
Can These Changes Be Reversed?
One of the biggest questions this research raises is whether the effects of stress on sperm can be reversed. The good news? Some evidence suggests that lifestyle changes and stress reduction techniques may help restore healthier sperm function.
Potential ways to reduce stress-related epigenetic changes include:
- Mindfulness and Meditation: Stress management techniques can help regulate cortisol levels and promote overall well-being.
- Regular Exercise: Physical activity has been shown to reduce stress and improve reproductive health.
- Healthy Diet: Nutrients like folate, zinc, and omega-3 fatty acids play a role in maintaining sperm quality.
- Adequate Sleep: Poor sleep can increase stress hormones, which may contribute to epigenetic changes.
- Therapy and Counseling: Addressing chronic stress through professional help can be beneficial for both mental and reproductive health.
While further research is needed, these lifestyle changes may provide a proactive way for men to optimize their reproductive health and reduce potential risks for their offspring.
Future Research: What’s Next?
While the current findings are groundbreaking, there are still many unanswered questions. Scientists are now investigating:
- How long-lasting these epigenetic changes are: Could stress from years before conception still impact sperm quality?
- Whether stress in different life stages (childhood vs. adulthood) affects sperm differently.
- How interventions like diet and therapy might help reverse these epigenetic effects.
If scientists can pinpoint precise mechanisms and timelines, it could open the door to new reproductive health strategies, including stress-reduction programs for prospective fathers.
Final Thoughts: The Importance of Paternal Well-Being
This study marks a major shift in our understanding of inheritance and genetics. The idea that sperm carries traces of a father’s stress challenges old assumptions and highlights the importance of mental health in reproductive planning.
If you’re planning to have children in the future, this research is a wake-up call. Taking care of your mental and physical health isn’t just about you—it could impact your future children as well.
As science continues to reveal how our experiences shape future generations, one thing becomes clear: both parents’ well-being matters long before conception.
