What are the best treatments for Hydranencephaly?

TL;DR: There is currently no curative treatment for hydranencephaly, so management focuses entirely on supportive, symptomatic care to improve the quality of life and comfort of the child. Treatment plans for hydranencephaly are highly individualized, emphasizing multidisciplinary medical support, the management of complications like hydrocephalus or seizures, and palliative care strategies.

What are the primary goals of treatment for hydranencephaly?

Because hydranencephaly is a condition where the cerebral hemispheres are absent and replaced by cerebrospinal fluid, the primary focus of medical intervention is not to restore brain function, but to provide comfort and manage secondary complications. The care team focuses on stabilizing the child’s physiological needs, such as nutrition, respiratory health, and pain management. Because every child with hydranencephaly presents with a unique set of neurological challenges, the treatment plan must be tailored by a pediatric neurology team to address the specific symptoms present in that individual.

How are complications of hydranencephaly managed clinically?

Management of hydranencephaly frequently involves addressing associated neurological issues that arise due to the lack of cortical tissue. Common clinical interventions include:

• Surgical intervention: If the child develops hydrocephalus (increased intracranial pressure), a neurosurgeon may place a shunt (e.g., ventriculoperitoneal shunt) to drain excess fluid and relieve pressure.


• Seizure management: Antiepileptic medications, such as levetiracetam (Keppra), phenobarbital, or valproic acid (Depakote), are often prescribed to manage seizure activity when present.


• Nutritional support: Many children with hydranencephaly have difficulty swallowing (dysphagia); a speech-language pathologist or gastroenterologist may recommend a gastrostomy tube (G-tube) to ensure adequate nutrition.


• Physical and Occupational Therapy: These therapies focus on managing muscle tone, preventing contractures, and ensuring the child is positioned comfortably to prevent skin breakdown.

Which specialists should be on the care team?

Due to the complexity of hydranencephaly, a multidisciplinary care team is essential to address the child's diverse needs. Families should seek care from a major pediatric medical center that can coordinate the following specialists:

• Pediatric Neurologist: To oversee neurological development and manage seizure protocols.


• Neurosurgeon: To monitor and treat hydrocephalus.


• Pediatric Physiatrist: To coordinate physical and occupational therapy goals.


• Palliative Care Specialist: To assist with symptom management, comfort-focused care, and emotional support for the family.


• Speech-Language Pathologist: To assess and manage swallowing safety.

Is there ongoing research or emerging treatments for hydranencephaly?

Currently, there are no clinical trials focused on reversing or curing hydranencephaly, as the condition involves the congenital absence of brain tissue. Research is primarily focused on understanding the underlying genetic or vascular causes that occur during fetal development. While the 37 members of the hydranencephaly community on DiseaseMaps.org share vital experiences regarding daily care and advocacy, clinical literature remains focused on palliative care and the optimization of supportive technologies to improve the daily life of affected children.

Next steps

• Consult with a pediatric neurologist to establish a comprehensive, individualized care plan.


• Connect with the hydranencephaly community at DiseaseMaps.org to share experiences and coping strategies with other families.


• Request a referral to a palliative care team early in the diagnosis to ensure a proactive approach to comfort and quality of life.


• Maintain a detailed log of medication responses and symptom changes to share with your multidisciplinary care team.
