Tailoring Materials for Epilepsy Imaging: From Biomarkers to Imaging Probes
Excising epileptic foci (EF) is the most efficient approach for treating drug‐resistant epilepsy (DRE). However, owing to the vast heterogeneity of epilepsies, EF in one‐third of patients cannot be accurately located, even after exhausting all current diagnostic strategies. Therefore, identifying bi...

Summary: | Excising epileptic foci (EF) is the most efficient approach for treating drug‐resistant epilepsy (DRE). However, owing to the vast heterogeneity of epilepsies, EF in one‐third of patients cannot be accurately located, even after exhausting all current diagnostic strategies. Therefore, identifying biomarkers that truly represent the status of epilepsy and fabricating probes with high targeting specificity are prerequisites for identifying the “concealed” EF. However, no systematic summary of this topic has been published. Herein, the potential biomarkers of EF are first summarized and classified into three categories: functional, molecular, and structural aberrances during epileptogenesis, a procedure of nonepileptic brain biasing toward epileptic tissue. The materials used to fabricate these imaging probes and their performance in defining the EF in preclinical and clinical studies are highlighted. Finally, perspectives for developing the next generation of probes and their challenges in clinical translation are discussed. In general, this review can be helpful in guiding the development of imaging probes defining EF with improved accuracy and holds promise for increasing the number of DRE patients who are eligible for surgical intervention.
A framework for understanding potential biomarkers of epilepsy is provided and they are classified them into three categories: functional, molecular, and structural aberrances during epileptogenesis. Then, the materials used to fabricate the imaging probes and their performances in defining the epileptic foci are highlighted. Imaging strategies overcoming the heterogenous nature of epilepsy are thoroughly discussed. |
