In today?s era of super specializations in nursing and the concept of nurse practitioners, a nurse no longer continues to be just an assistant, but is actually following up, monitoring, and treating the patients at her own. With the exponential growth of science in general and nursing sciences in particular, it becomes very important for present day nurses to keep themselves updated in recent advances. As the medical sciences have become vast, we all now need to select and then excel in the fields of our chosen nursing specializations, super specializations, and sub specializations. Neurosciences and Critical Care Nursing becomes all the more important for nurses as during acute emergencies a vigilant and updated nurse can help save many lives in ICU settings as well as can go a long way to reduce morbidity and mortality. The role of a nurse expert acquires more importance in our society in view of limited availability of specialists and super specialists where patients are left with no choices except to go to unqualified and self-styled doctors.
