Photic Sneeze Reflex (PSR) is an involuntary sneezing response to bright light exposure. It is also known as ACHOO syndrome, which stands for Autosomal Dominant Compelling Helio-Ophthalmic Outburst syndrome. This condition affects about 18-35% of the world's population, and many people wonder if it is hereditary or not.
What Causes Photic Sneeze Reflex?
The exact cause of PSR is not yet known, but researchers believe that it is related to the way the brain processes visual information. When bright light enters the eyes, it stimulates the optic nerve, which is connected to the trigeminal nerve. The trigeminal nerve is responsible for controlling facial sensations, including sneezing.
PSR is more common in people with lighter-colored eyes, and it tends to run in families. This has led researchers to believe that there may be a genetic component to this condition.
Is Photic Sneeze Reflex Hereditary?
Studies have shown that PSR is hereditary, and it follows an autosomal dominant pattern of inheritance. This means that if one parent has PSR, there is a 50% chance that their child will also have the condition.
However, not all people with PSR have a family history of the condition. It is also possible for PSR to occur spontaneously, without any known genetic cause.
How to Manage Photic Sneeze Reflex?
There is no cure for PSR, but there are ways to manage the condition. The most effective way to avoid triggering a sneeze is to avoid bright light, especially in situations where sneezing could be dangerous, such as while driving.
Wearing sunglasses or a hat with a brim can also help to reduce the amount of light that enters the eyes. Some people find that taking antihistamines or nasal decongestants can help to reduce the frequency of sneezing.
Conclusion
Photic Sneeze Reflex is a common condition that affects many people around the world. While the exact cause of the condition is not yet known, it is believed to have a genetic component, and it tends to run in families. If you have PSR, it is important to take steps to manage the condition and avoid situations where sneezing could be dangerous.
