What are the best treatments for Lissencephaly?

There is currently no cure for Lissencephaly; instead, treatment is strictly supportive and focused on managing symptoms to improve quality of life. Medical management for Lissencephaly typically involves a multidisciplinary approach centered on seizure control, physical therapy, and nutritional support to address the developmental challenges associated with this brain malformation.

What are the primary medical treatments for Lissencephaly?

Because Lissencephaly involves the "smooth brain" condition, patients often experience intractable epilepsy. First-line treatment focuses on anti-seizure medications (ASMs) such as levetiracetam (Keppra), valproic acid (Depakene), or clobazam (Onfi). While these medications can manage seizure frequency, they must be titrated carefully by a pediatric neurologist. In cases of severe feeding difficulties caused by poor muscle tone or swallowing dysfunction, a gastrostomy tube (G-tube) is often recommended to ensure adequate nutrition and prevent aspiration pneumonia.

What non-pharmacological therapies help manage Lissencephaly?

Comprehensive care for Lissencephaly requires early and consistent intervention to maximize developmental potential. Therapy plans are highly personalized based on the severity of the malformation and the individual’s motor skills. Common interventions include:

• Physical Therapy: To improve muscle tone, prevent contractures, and assist with mobility.


• Occupational Therapy: To develop fine motor skills and assist with daily living tasks.


• Speech and Language Therapy: To address swallowing difficulties (dysphagia) and communication delays.


• Orthopedic Intervention: To manage scoliosis or hip dysplasia, which are common secondary complications.

Which specialists should be on the care team?

Managing Lissencephaly requires a coordinated team of medical professionals. Your care team should ideally include a pediatric neurologist, a geneticist, a physiatrist, a physical therapist, an occupational therapist, and a speech-language pathologist. Regular follow-ups with a gastroenterologist and an orthopedist are also essential to manage the systemic impacts of Lissencephaly.

Are there emerging treatments for Lissencephaly?

Research into Lissencephaly is currently focused on understanding the underlying genetic mutations, such as those in the PAX6, DCX, and LIS1 genes. While there are no gene therapies currently approved for clinical use, researchers are exploring molecular pathways that may one day offer targeted interventions. Families are encouraged to consult ClinicalTrials.gov for the most current information on registry studies or potential experimental trials.

Next steps

• Consult with a pediatric neurologist to establish a seizure management plan.


• Connect with the 11 Lissencephaly families on DiseaseMaps.org to share experiences and coping strategies.


• Request a referral to a genetic counselor to understand the recurrence risks for your family.


• Reach out to organizations like the National Organization for Rare Disorders (NORD) for further support.
