There are various types of serious pediatric neurological diseases, although the absolute number of children with either of them is small. These children often have life-threatening conditions with severe disability and rely on medical technologies. Each child follows a different illness trajectory, which makes it difficult to predict his/her prognosis. Given the multiple treatment options, it becomes harder to know when "enough" is enough and what is best for the child. When it comes to critical decision-making, we, as healthcare providers, need to develop a trustful relationship with the parents and promote shared decision-making to fulfill their child's best interest. It is crucial to know what the parents hope and fear, and provide them with access to comprehensive, evidence-based information about their child's current and potential healthcare needs. In this article, four complex ethical issues are reviewed. A broad and constructive discussion is long awaited to ensure that these children's lives are enhanced to their best potential and treated with dignity in our society.
