Is Congenital bilateral perisylvian syndrome contagious?

Congenital bilateral perisylvian syndrome is not contagious; it is a neurological condition caused by abnormal development of the brain's cerebral cortex during fetal gestation. There is absolutely no risk of transmission through touch, proximity, or daily interaction, as the condition is rooted in neurodevelopmental processes rather than infectious agents.

Is Congenital bilateral perisylvian syndrome contagious?

It is important to state clearly that Congenital bilateral perisylvian syndrome is not an infectious disease. It cannot be spread from person to person through coughing, sneezing, skin-to-skin contact, sharing utensils, or any other form of social interaction. Because this is a developmental brain disorder, there is no biological mechanism for transmission. Living with, caring for, or spending time with an individual diagnosed with Congenital bilateral perisylvian syndrome poses zero risk of infection to family members, caregivers, or peers.

What causes Congenital bilateral perisylvian syndrome?

Congenital bilateral perisylvian syndrome (CBPS), also known as Worster-Drought syndrome, is caused by polymicrogyria—a condition where the surface of the brain develops with too many, abnormally small folds. This structural abnormality occurs during prenatal development, typically between the 12th and 24th weeks of pregnancy. While the exact trigger for each case is not always identified, current research suggests that Congenital bilateral perisylvian syndrome may arise from a combination of factors:

• Genetic mutations: Certain genes involved in neuronal migration and cortical organization have been implicated.


• In-utero vascular injury: Disruption of blood flow to the developing fetal brain.


• Prenatal infections: Exposure to specific viruses (such as cytomegalovirus) during critical stages of brain development.


• Environmental factors: Exposure to certain toxins or metabolic disturbances during early pregnancy.

Why is there stigma surrounding this condition?

Stigma often arises when the public confuses neurological or developmental disorders with communicable diseases. Because Congenital bilateral perisylvian syndrome presents with distinct symptoms—such as oromotor dysfunction, difficulty swallowing (dysphagia), and speech impairments—bystanders who are unfamiliar with the condition may mistakenly assume the individual is ill with something contagious. This is a common misconception that causes unnecessary isolation. Education is our best tool; by understanding that Congenital bilateral perisylvian syndrome is a fixed structural brain difference rather than an active illness, we can replace fear with empathy and support.

Are there environmental triggers to worry about?

Once a child is born with Congenital bilateral perisylvian syndrome, their environment does not trigger the condition or make it worse in a way that would suggest contagion. The structural brain changes are established before birth. While individuals with this syndrome may be more susceptible to secondary complications like aspiration pneumonia—which is a result of swallowing difficulties—these are not "contagious" illnesses. It is vital for families to know that the condition does not evolve or spread through environmental exposure after birth.

Next steps

• Consult a neurologist: Work with a pediatric neurologist or a specialist in neurodevelopmental disorders to manage symptoms like seizures or oromotor issues.


• Join the community: Connect with the 45 members on DiseaseMaps.org who are living with or caring for someone with Congenital bilateral perisylvian syndrome to share experiences and reduce social isolation.


• Seek specialized therapy: Engage speech-language pathologists and occupational therapists who specialize in feeding and communication disorders related to cortical malformations.


• Educate your circle: Share reliable, fact-based information with schools and extended family to dispel myths regarding the nature of the syndrome.
