I want to find all instances of neurologic disorders and diseases of the nervous system (ICD-10 codes G0-G9) in the i2b2 database, along with any related images stored in the BIRN oasis. Additionally, I want to include any medications related to central nervous system agents, specifically anticonvulsants. The time frame for this search is not limited, and the results should be as accurate as possible.
