For Healthcare Professionals

Collaborating to Advance LGS Care & Research

Healthcare ProfessionalsAt the LGS Foundation, we recognize the power of collaboration between expert neurologists, epileptologists, neurosurgeons, neuroscientists, and allied health professionals. Together, we are accelerating diagnoses, improving access to comprehensive treatment options, and empowering families with personalized care plans—ultimately enhancing quality of life and long-term outcomes for individuals living with Lennox-Gastaut Syndrome (LGS).


Could it be Lennox-Gastaut Syndrome (LGS)?

LGS is one of the most severe Developmental and Epileptic Encephalopathies (DEEs), often evolving from early-life epilepsy that remains resistant to treatment. Characterized by a distinct electroclinical pattern, LGS disrupts typical brain development and is notoriously difficult to control. Over time, it can become neurodegenerative, leading to premature mortality.

Know the 4 Core Features of LGS

Understanding the Evolution of LGS

LGS does not appear at birth. It typically emerges between the ages of 3 to 5 following early-life seizures or brain injury. However, onset can occur later in childhood. Early identification and comprehensive care planning are essential

Help shape the future of LGS care and research. 

We invite clinicians to contribute to the LGS Learn from Every Patient Database, a global patient registry and natural history study designed to: 

  • Collect longitudinal clinical, diagnostic, and treatment data
  • Identify trends and patterns across the LGS population
  • Accelerate breakthroughs in precision medicine
  • Improve real-world outcomes through shared learning

Why Participate? 

By contributing patient data, you support efforts to: 

  • Understand the variability of LGS presentations and comorbidities
  • Strengthen clinical trial readiness
  • Guide the development of targeted therapies

Together, we can ensure that every patient counts-and every experience informs progress.

LGS Caregiver Support Community 

Connect families with our private online Caregiver Support Community, offering peer support, resources, and guidance from diagnosis through every stage of the journey.

Complimentary Educational Materials 

We provide free LGS educational materials for clinicians to share with patients and families. 

To order materials: Email info@lgsfoundation.org

Appropriate use of LGS-specific ICD-10 codes can: 

  • Make it easier to secure coverage for indicated medications and medical testing required for recognized co-morbidities of LGS
  • Allow researchers to track how many people have LGS

Recommended Codes:

  • G40.81 Lennox-Gastaut Syndrome
    • G40.811  …… not intractable, with status epilepticus
    • G40.812 …… not intractable, without status epilepticus
    • G40.813 …… intractable, with status epilepticus
    • G40.814 …… intractable, without status epilepticus
