Standard of Care & Symptom Management
At a Glance
Pallister-Killian Syndrome requires personalized, supportive care to manage its wide range of symptoms. Standard treatments focus on managing epilepsy with medications, resolving feeding difficulties through safe nutritional support, treating sleep apnea, and using rehabilitative therapies.
Because Pallister-Killian Syndrome (PKS) is a highly variable condition, there is no single “cure” or “universal” treatment plan [1][2]. Instead, the standard of care is supportive management—a tailored approach that focuses on treating each child’s unique symptoms to improve their comfort, safety, and development [3][4].
Managing Neurological Challenges and Epilepsy
Epilepsy is a common feature of PKS, often appearing in early childhood [1].
- Seizure Control: The goal of treatment is to reduce or eliminate seizures while minimizing side effects. Medications called Anti-Epileptic Drugs (AEDs) are the primary treatment [1].
- Photosensitivity: Some children with PKS have a specific sensitivity to flashing lights (photosensitivity), which can trigger seizures [1]. Your neurologist may use a low-frequency light test during an EEG (brain wave test) to check for this marker.
- Monitoring: Regular neurological follow-ups are necessary to adjust medications as your child grows and to monitor for any new seizure types, such as sudden muscle jerks (myoclonic seizures), staring spells, or infantile spasms [1][5].
Managing Feeding Difficulties
Severe feeding difficulties, failure to thrive, and severe reflux are common daily struggles due to low muscle tone (hypotonia) and an enlarged tongue (macroglossia) [2].
- Swallow Studies: Doctors may use specialized tests to ensure your child isn’t aspirating (inhaling) food or liquid into their lungs while eating.
- Nutritional Support: When feeding by mouth becomes unsafe or too physically exhausting for the child, many families opt for a gastrostomy tube (G-tube). This provides a safe, direct route for nutrition and can significantly reduce the stress and anxiety around daily feeding.
Managing Sleep and Breathing
Sleep disorders, particularly sleep-disordered breathing, are very common in PKS [6].
- Diagnosis: Doctors often use videopolysomnography (a detailed sleep study) to look for signs of obstructive sleep apnea, where breathing stops and starts during sleep [6].
- CPAP/BiPAP: For many children, Positive Airway Pressure (PAP) therapy—using a machine that gently blows air into a mask during sleep—can significantly improve sleep quality and daytime energy [7][8].
- Surgical Options: In some cases, a surgeon may recommend removing the tonsils and adenoids (adenotonsillectomy) to clear the airway, although the effectiveness of this surgery can vary in children with complex genetic syndromes [9][10].
The Role of Rehabilitative Therapies
Therapy is the “engine” of development for children with PKS. It is most effective when it is personalized to your child’s specific sensory profile—how they react to touch, sound, and movement [4].
- Physical Therapy (PT): Focuses on managing hypotonia and helping children gain strength and balance for sitting, standing, or walking [4].
- Occupational Therapy (OT): Helps with “activities of daily living,” such as grasping toys, processing visual information, and managing sensory sensitivities (like a strong dislike of certain textures) [4].
- Speech-Language Pathology (SLP): Addresses communication challenges, which may include childhood apraxia of speech [11]. SLPs also play a vital role in managing swallowing safety and feeding mechanics [2].
A Personalized Approach
While there are currently no international “consensus guidelines” for PKS, your medical team should focus on multidisciplinary surveillance [2][6]. This means regular check-ups for vision, hearing, and dental health to catch and treat problems before they impact your child’s quality of life [2][12].

Questions to Ask Your Doctor
Curated prompts to bring to your next appointment.
- 1.What is the most appropriate Anti-Epileptic Drug (AED) for my child's specific seizure type, and are there medications we should avoid?
- 2.Given the risk of photosensitivity in PKS, should we take specific precautions during EEG testing or in daily life?
- 3.If my child is diagnosed with obstructive sleep apnea, would you recommend a CPAP machine or a surgical evaluation (like an adenotonsillectomy)?
- 4.Can you help us coordinate a 'sensory profile' evaluation to better tailor my child's physical and occupational therapy?
- 5.Can we schedule a swallow study to evaluate my child's feeding safety and discuss options for nutritional support?
