Insights
A new Multi-categorical Hydrocephalus Classification (Mc HC) system comprehensively addresses hydrocephalus complexity. This system effectively categorizes diverse aspects of the condition, improving clinical understanding and patient state expression.
Area of Science:
- Neurology
- Neurosurgery
- Medical Classification Systems
Background:
- Hydrocephalus involves disturbed cerebrospinal fluid (CSF) circulation, lacking a unified classification system.
- Existing classifications address specific criteria but fail to comprehensively cover all aspects of hydrocephalus.
Observation:
- A novel "Multi-categorical Hydrocephalus Classification" (Mc HC) system was developed.
- The Mc HC system incorporates ten distinct categories, including onset, cause, lesion, symptomatology, CSF circulation, ICP dynamics, chronology, and post-intervention status.
Findings:
- Historical classification trends show a tendency towards pathophysiology, specifically CSF or ICP dynamics.
- The Mc HC system was derived from a review of 14 representative publications spanning 100 years.
Implications:
- The Mc HC system is highly effective for expressing individual hydrocephalus patient states.
- It facilitates understanding of past, present, and potential future chronological changes in hydrocephalus cases.
Objective:
Hydrocephalus is a complex pathophysiology with disturbed cerebrospinal fluid (CSF) circulation. There are numerous numbers of classification trials published focusing on various criteria, such as associated anomalies/underlying lesions, CSF circulation/intracranial pressure patterns, clinical features, and other categories. However, no definitive classification exists comprehensively to cover the variety of these aspects. The new classification of hydrocephalus, "Multi-categorical Hydrocephalus Classification" (Mc HC), was invented and developed to cover the entire aspects of hydrocephalus with all considerable classification items and categories.
Materials And Method:
Ten categories include "Mc HC" category I: onset (age, phase), II: cause, III: underlying lesion, IV: symptomatology, V: pathophysiology 1-CSF circulation, VI: pathophysiology 2-ICP dynamics, VII: chronology, VII: post-shunt, VIII: post-endoscopic third ventriculostomy, and X: others. From a 100-year search of publication related to the classification of hydrocephalus, 14 representative publications were reviewed and divided into the 10 categories.
Results And Discussion:
The Baumkuchen classification graph made from the round o'clock classification demonstrated the historical tendency of deviation to the categories in pathophysiology, either CSF or ICP dynamics.
Conclusion:
In the preliminary clinical application, it was concluded that "Mc HC" is extremely effective in expressing the individual state with various categories in the past and present condition or among the compatible cases of hydrocephalus along with the possible chronological change in the future.

Data are classified based on whether they are measurable or not. Categorical data cannot be measured; instead, it can be divided into categories. For example, if Y denotes a person's party affiliation, some examples of Y include...
