Competetive landscape analysis in Epilepsy

Overview of Epilepsy Treatment Market

Epilepsy is a chronic neurological disorder characterized by recurrent and unpredictable seizures that affect approximately 50 million people worldwide. It is caused by abnormal excessive, synchronous neuronal activity in the brain. The term “epilepsy” encompasses a range of seizure types and syndromes that may differ in their underlying pathophysiology, clinical presentation, and treatment response. Over the years, advances in understanding its neurobiology have led to a more nuanced categorization and management approach. Today, treatment is not only symptomatic—with attempts to suppress seizures—but is also oriented toward improving quality of life, reducing comorbidities, and exploring precision or even curative therapeutic options.

Definition and Epidemiology of Epilepsy

Epilepsy is defined as a brain disorder with an enduring predisposition to generate epileptic seizures, accompanied by neurobiological, cognitive, psychological, and social consequences. The disorder is multifactorial, with variations in prevalence, age of onset, and seizure types. Epidemiological studies indicate that epilepsy affects individuals across all age groups, with slightly higher incidence rates in lower‐income countries due to factors such as limited access to medical care and higher rates of infections and head injuries. Although strictly defined epileptic phenomena have been recognized for centuries, modern diagnostic criteria—incorporating advanced neuroimaging and electrophysiological evaluations—have improved disease classification and epidemiologic estimates. In essence, epilepsy is not a single disease but a spectrum of disorders with highly heterogenous clinical, neurophysiological, and genetic characteristics.

Recent studies have emphasized that up to 30%–40% of patients remain resistant to available antiseizure medications (ASMs), with a significant proportion having a high burden of comorbidity that compounds the overall public health and socio‐economic impact of the disease. The global burden of epilepsy manifests not only in medical costs, but also in lost productivity, social stigmatization, and long‐term disability. Such complexity has driven a shift in research towards innovative treatment modalities that go beyond the traditional “one‐drug for all” approach.
