Seizures: Classification

Seizures: Classification

Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:

Background:

Syncope, a transient loss of consciousness due to reduced brain blood flow, poses diagnostic challenges.
Machine learning (ML) shows promise in analyzing complex physiological data for medical diagnoses.

Purpose of the Study:

To evaluate the effectiveness of Support Vector Machine (SVM) for classifying neuro-mediated syncope.
To assess SVM model performance using patient physiological data from Head-up Tilt Tests.

Main Methods:

Utilized physiological data collected during Head-up Tilt Tests in clinical settings.
Implemented Support Vector Machine (SVM) for binary classification of syncope.
Employed train-test-split and K-fold cross-validation for model evaluation.

Main Results:

The SVM model achieved significant accuracy in classifying neuro-mediated syncope.
Performance was validated using standard statistical indices, confirming model robustness.
The classification approach proved effective in a real-world clinical context.

Conclusions:

SVM-based classification is a viable and effective method for the proactive diagnosis of syncope.
This ML approach can aid clinicians in identifying neuro-mediated syncope efficiently.
Further research can explore advanced ML techniques for syncope prediction.
