A Novel Classification for Chronic Hydrocephalus in Adults

ithout a clear understanding of the definition and diagnostic criteria of a disease, it becomes difficult to accurately recognize and classify the corresponding disorder. Unclear classifications lead to confusion and varying treatment methods for different groups of patients with the same disorder. As the research on chronic hydrocephalus in adults (CHiA) progresses and diagnostic techniques and treatment options become more advanced, the frequency of diagnosing and treating CHiA has increased rapidly.1-6 Therefore, it is crucial to identify and differentiate these patients from others who present with similar clinical symptoms but have a different underlying condition.' Establishing the distinction between CHiA and disorders that share overlapping symptoms and signs is of utmost importance.8 Lastly, identifying suitable candidates for shunt surgery and predicting the postsurgery outcomes for patients with CHiA pose significant challenges.9 This is because of the potential reversibility of the symptoms, making it difficult to determine who will benefit from shunt surgery and have a favorable outcome.'
