Eligibility
Inclusion criteria
Inclusion criteria: 1. Case Group (Drug-Resistant Epilepsy): Patients diagnosed with drug-resistant epilepsy and scheduled for epileptogenic focus resection. Inclusion criteria for the case group: (1) Age >=1 month and =18 years). 2. Control Group (Non-Epilepsy): Patients undergoing surgery for other neurosurgical conditions (e.g., acute intracranial hemorrhage within 24 hours, craniotomy with aneurysm clipping for non-epilepsy reasons) and without systemic immune system diseases, matched for age and gender with the case group. Inclusion criteria for the control group: (1) Age >=1 month and <=90 years. (2) Undergoing craniotomy for non-epilepsy-related reasons (e.g., acute intracranial hemorrhage within 24 hours, craniotomy with aneurysm clipping for non-epilepsy reasons). (3) No history of epilepsy, no other neurological disease diagnosis, and no diseases affecting immune function. (4) The patient or family member is able to understand and sign the informed consent form.
Exclusion criteria
Exclusion criteria: 1. Exclusion criteria for the case group (drug-resistant epilepsy group): (1) Coexisting other severe neurological diseases (such as brain tumor, stroke, multiple sclerosis, etc.). (2) Coexisting severe immune system diseases or autoimmune disorders. (3) Suffering from severe systemic infection or inflammatory disease. (4) Receiving treatments that may affect immune response (such as chemotherapy, radiotherapy, immunosuppressive therapy, etc.). (5) Pregnant or lactating women. (6) History of psychiatric illness, unable to cooperate with the study. 2. Exclusion criteria for the control group (non-epilepsy): (1) Coexisting severe immune system diseases or autoimmune disorders. (2) Suffering from severe systemic infection or inflammatory disease. (3) Receiving treatments that may affect immune response. (4) Pregnant or lactating women. (5) History of psychiatric illness, unable to cooperate with the study.
