Arteries of the Lower Limbs

Arteries of the Lower Limbs

Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...

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:

Post-stroke epilepsy (PSE) is a significant complication following ischemic stroke.
Existing prediction models for PSE lack sufficient accuracy and population applicability.
Machine learning (ML) presents a promising avenue for developing more precise PSE prediction models.

Purpose of the Study:

To develop and validate machine learning models for predicting post-stroke epilepsy (PSE) in ischemic stroke patients.
To compare the performance of ML models against conventional methods.
To enhance the transparency and interpretability of PSE prediction models.

Main Methods:

Retrospective cohort study involving ischemic stroke patients from two centers.
Utilized 33 candidate features for model development.
Employed six ML algorithms, including Naive Bayes (NB), and the Shapley Additive Explanation (SHAP) method for interpretation.
Validated models using an independent cohort.

Main Results:

The Naive Bayes (NB) model demonstrated the best performance in predicting PSE, achieving an area under the receiver operating characteristic curve (AUC) of 0.757.
Optimal features identified by the Boruta method included NIHSS score, hospital length of stay, D-dimer level, and cortical involvement.
The NB model achieved a sensitivity of 0.739 and specificity of 0.720 at a 20% risk threshold, outperforming the reference model.

Conclusions:

Machine learning models can accurately predict PSE using readily available variables.
The developed models offer improved strategies for resource allocation and management of high-risk patients.
SHAP analysis enhances model transparency, aiding clinicians in understanding prediction reliability.
