The International Post-Stroke Epilepsy Research Repository (IPSERR): The study aims to collate and categorize data reported by post-stroke epilepsy (PSE) researchers and lodge it within the IPSERR. Using the IPSERR database, we will conduct two individual patient data (IPD) analyses: (1) determine epilepsy, functional, and cognitive outcomes in stroke patients who develop post-stroke seizure and (2) build and validate post-stroke epilepsy prediction model and compare performance against existing models.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Mortality (modified Rankin Scale = 6) | The modified Rankin Scale (mRS) is a clinician-reported measure of global disability for evaluating recovery from stroke. It ranges from 0 (no symptoms) to 6 (death). | At 1 year, 2 year, and 5 year follow-up | |
Primary | Poor functional outcome (modified Rankin Scale 3-6) | The modified Rankin Scale (mRS) is a clinician-reported measure of global disability for evaluating recovery from stroke. It ranges from 0 (no symptoms) to 6 (death), with 0-2 indicating a good functional outcome and 3-6 indicating a poor functional outcome. | At 1 year, 2 year, and 5 year follow-up | |
Primary | Seizure frequency | Number of seizures post-stroke identified clinically or based on an electroencephalogram (EEG). | At 1 year, 2 year, and 5 year follow-up | |
Primary | Seizure severity | Defined by impaired awareness and the presence of bilateral tonic or clonic seizures. | At 1 year, 2 year, and 5 year follow-up | |
Primary | Occurrence or frequency of status epilepticus | Status epilepticus is defined as a seizure or series of seizures lasting more than 30 minutes without recovery of consciousness based on electroencephalogram (EEG) findings. | At 1 year, 2 year, and 5 year follow-up | |
Primary | Length of hospital stay | The duration of hospital admission for a stroke is measured in days. | At 1 year, 2 year, and 5 year follow-up | |
Primary | Cognitive decline assessed on an 11-question Mini-Mental State Examination (MMSE) tool or a 30-point Montreal Cognitive Assessment (MoCA) scale | MMSE is tests cognitive function. It is scored out of 30, with a score of =26 indicating cognitive impairment. MoCA assesses mild cognitive dysfunction. It is scored out of 30, with a score of =24 indicating cognitive impairment. | At 1 year, 2 year, and 5 year follow-up | |
Secondary | Recurrent stroke | A diagnosis of a subsequent stroke will be made based on neuroimaging. | At 1 year, 2 year, and 5 year follow-up | |
Secondary | Antiseizure medication discontinuation | Switching of antiseizure medication (ASM) defined as discontinuation of one ASM and starting of another due to adverse events or treatment ineffectiveness. | At 1 year, 2 year, and 5 year follow-up | |
Secondary | Treatment adverse events | Adverse events are defined as any side effects occurring due to antiseizure medication administration during the course of the study. | At 1 year, 2 year, and 5 year follow-up | |
Secondary | Depression assessed on 21-item Hamilton Depression Rating Scale (HAM-D) | HAM-D is a tool used to assess depression symptoms. Depression post-ASM administration is defined as HAM-D score of 0-13 mild; 14-17 mild to moderate; >17 moderate to severe depression. | At 1 year, 2 year, and 5 year follow-up | |
Secondary | Anxiety assessed on 14-item Hamilton Anxiety Rating Scale (HAM-A) | HAM-A is a psychological questionnaire that measures the severity of a patient's anxiety. Anxiety post-ASM administration is defined as HAM-A score of <17 mild; 18-24 moderate; 25-30 moderate to severe anxiety. | At 1 year, 2 year, and 5 year follow-up |
