What are the best treatments for Congenital bilateral perisylvian syndrome?

Congenital bilateral perisylvian syndrome (CBPS) is primarily managed through multidisciplinary supportive therapies, as there is currently no curative treatment for the underlying cortical malformation. Clinical management focuses on symptom-specific interventions, including speech therapy for oromotor dysfunction, specialized educational support for cognitive delays, and pharmacological management of epilepsy.

What are the primary treatment goals for Congenital bilateral perisylvian syndrome?

Because Congenital bilateral perisylvian syndrome is a complex neurological disorder characterized by bilateral polymicrogyria, treatment is individualized based on the specific clinical presentation of the patient. The primary goal is to maximize the patient's functional independence and quality of life. For the 45 members in the DiseaseMaps community living with Congenital bilateral perisylvian syndrome, treatment plans often prioritize the stabilization of seizures and the improvement of communication skills, which are frequently impacted by pseudobulbar palsy.

What therapies and interventions are used for management?

Non-pharmacological interventions are the cornerstone of care for patients with Congenital bilateral perisylvian syndrome. Because oromotor dysfunction—leading to difficulties with speech, chewing, and swallowing—is a hallmark of the condition, early and consistent intervention is vital. A typical care plan often includes:

• Speech and Language Therapy: Essential for addressing dysarthria and language delays.


• Occupational Therapy: Focuses on fine motor skills and sensory integration to assist with activities of daily living.


• Physical Therapy: Used to manage muscle tone abnormalities and improve gross motor coordination.


• Nutritional Support: Speech-language pathologists often work alongside nutritionists to mitigate aspiration risks associated with dysphagia.


• Specialized Educational Services: Tailored curriculum to support cognitive challenges and learning disabilities associated with Congenital bilateral perisylvian syndrome.

How is epilepsy managed in patients with this syndrome?

Seizures occur in a significant percentage of individuals with Congenital bilateral perisylvian syndrome. When medical management is required, neurologists typically prescribe antiepileptic drugs (AEDs). Common medications may include levetiracetam (Keppra), valproate (Depakene, Depakote), or lamotrigine (Lamictal), though the choice depends entirely on the seizure type and the patient's individual response. It is crucial to work closely with a pediatric or adult neurologist, as some patients may develop drug-resistant epilepsy, necessitating the exploration of alternative therapies or dietary interventions under strict medical supervision.

Who should be on the multidisciplinary care team?

Managing Congenital bilateral perisylvian syndrome requires a coordinated effort between various medical specialists to address the diverse neurological and systemic manifestations. An ideal care team for a patient with Congenital bilateral perisylvian syndrome includes:

• A Pediatric or Adult Neurologist (specializing in epilepsy)


• A Speech-Language Pathologist (SLP)


• A Physical and Occupational Therapist


• A Clinical Geneticist for ongoing counseling and family planning


• A Developmental Pediatrician or Physiatrist

Next steps

• Consult a neurologist to establish a baseline for seizure activity and cognitive monitoring.


• Connect with a speech-language pathologist experienced in neurodevelopmental disorders to address oromotor dysfunction.


• Join the DiseaseMaps.org community to share experiences and coping strategies with other families navigating the complexities of this diagnosis.


• Maintain a detailed log of symptoms and medication responses to assist your medical team in refining your treatment plan.
