New developments in genetics and gene technology have brought about several shifts that have affected epilepsy care regarding diagnosis, treatment, and prevention. In essence, this particular manuscript also discusses the application of genetic tests in epilepsy management, as well as the implications user-personalized treatment has on the practice of medicine. Molecular diagnostics has improved the diagnostic capacity of genetic testing to link specific genes to epilepsy and its diverse types, hence improving the identification of specific treatment plans. However, the implementation of these technologies in clinical setting has various ethical implications such as informed consent, privacy and confidentiality impacts on psychological well being of patients, and genetic discrimination. The manuscript also discusses the advantages and drawbacks of genetic testing in cases of hereditary epilepsy diseases as a diagnostic tool and family planning tool. However, like any other tool, some issues may arise from the genetic testing process, such as false positive or false negative conclusions and ethical issues.
