Abstract

This seminar addresses the complexity of the management of epilepsy in adults with intellectual development disorders (IDD), advocating holistic and multidisciplinary care aligned with the learning objectives of the International League Against Epilepsy. Epilepsy is significantly more prevalent in people with IDD, presenting unique diagnostic, therapeutic, and psychosocial challenges. Accurate diagnosis is hampered by limitations in communication, necessitating reliance on caregivers' observations. In adults with IDD and epilepsy, utilization of diagnostic tools, e.g., video electroencephalograph (EEG) monitoring, is helpful but can be challenging. Management requires careful consideration of cognitive and behavioral comorbidities and the effects of antiseizure medications (ASMs) on cognitive function and quality of life (QoL). Personalized treatment plans should balance seizure control against ASM side effects, prioritizing therapeutic goals aligned with individual patient needs. Effective multidisciplinary care involves primary care physicians, neurologists, psychiatrists, psychologists, social workers, therapists, and specialized nursing staff. Transition periods, including from pediatric to adult care, and from the family home to professional care, represent critical phases requiring structured planning and collaboration among health and social-care providers, patients, and caregivers. Current gaps in integrated care include the need for targeted therapeutic approaches, more tailored cognitive and behavioral assessment tools, guidelines for managing pregnancy and hormonal considerations, management of commonly associated comorbidities, including non-epileptic paroxysmal events, and reduction of preventable morbidity and mortality, including sudden death. This seminar emphasizes the necessity of addressing these gaps to advance care standards, promote research, and ultimately improve patient outcomes. The manuscript includes two anonymized illustrative clinical case studies. Practical recommendations include systematic reassessment of underlying etiologies, including genetic counseling and testing, reviewing the electroclinical diagnosis, careful selection and titration of ASMs to minimize cognitive and behavioral impacts, and structured transition. Addressing these challenges and implementing an integrated care model could significantly enhance QoL for adults living with IDD and epilepsy.
