This calculation tool combines two distinct yet complementary approaches derived from the MRC Multicentre Trial for Early Epilepsy and Single Seizures (MESS) to assess the likelihood of seizure recurrence and inform decision-making in clinical and practical scenarios, including driving eligibility and treatment planning.
The “When is it Safe to Return to Driving Following First-Ever Seizure” Tool is designed to assess the safety and timing for resuming driving after a first seizure. It uses clinical and imaging data to calculate individualized risk and provides outputs for both seizure recurrence risk and COSY.
This tool provides the cumulative risk of seizure recurrence over time and the likelihood of experiencing a seizure in the upcoming months, based on the type of autoimmune encephalitis and the patient’s age group.
This tool estimates the risk of seizure recurrence in patients with generalized tonic-clonic seizures (GTCs) after antiseizure medication (ASM) tapering. The predictions differentiate between patient-initiated and physician-initiated tapering and assess how treatment status (treated vs. untreated) impacts outcomes. The COSY (Chance of an Occurrence of a Seizure in the next Year) field calculates the likelihood of seizure frequency changes within the following year.
This calculator estimates the risk of seizure recurrence and the predicted Chance of an Occurrence of a Seizure in the next Year (COSY) over time for adults experiencing a first tonic-clonic seizure. The tool leverages clinical and imaging data to provide personalized predictions based on epilepsy type and other factors.
This tool estimates the risk of seizure recurrence and Chance of an Occurrence of a Seizure in the next Year (COSY) following a first unprovoked seizure in individuals diagnosed with dementia. The predictions focus on understanding the varying risks associated with different dementia subtypes, as explored in the study “Risk of epilepsy diagnosis after a first unprovoked seizure in dementia” (Mahamud et al., 2020).
This tool analysis epilepsy risk following a first posttraumatic seizure (PTS). The study utilized a register-based cohort design and included 4,239 individuals with a first seizure, of whom 2,286 had a prior traumatic brain injury (TBI) and 1,953 served as non-TBI controls. Data were sourced from Swedish national healthcare and population registers, covering hospitalizations for TBI between 2000 and 2010, with follow-up extending up to 10 years (median: 2.0 years). The median age was 51 years in the TBI group and 67 years in the non-TBI group. High diagnostic accuracy (over 90%) was achieved through the use of validated registry data.
This tool providesthe cumulative risk of seizure recurrence over time and the likelihood of experiencing a seizure in the upcoming months, based on the presence or absence of perilesional edema in solitary calcified neurocysticercosis.
The SeLECT scores are available on a dedicated website. This tool provides cumulative seizure recurrence risk and COSY predictions for both unprovoked (remote symptomatic, RSyS) and provoked (acute symptomatic, ASyS) seizures following ischemic stroke. Note: For acute symptomatic seizures, all cases are initially grouped here without further stratification. If additional data are available, it is recommended to use the SeLECT-ASyS tool on the SeLECT calculator website for more precise stratification.
The ASM Withdrawal Risk Retrieval Prediction Tool calculates the cumulative risk of seizure recurrence and long-term outcomes (e.g., seizure freedom) following the withdrawal of antiaeizure medications (ASMs) in seizure-free individuals. This tool is informed by meta-analytical data to guide individualized decision-making.
This tool predicts the risk of seizure recurrence and Chance of an Occurrence of a Seizure in the next Year (COSY) after febrile status epilepticus (FSE), particularly focusing on hippocampal abnormalities detected through MRI. It provides an estimate of seizure recurrence risk and the likelihood of hippocampal sclerosis (HS) or mesial temporal lobe epilepsy (MTLE) based on detailed diagnostic imaging and patient characteristics.
This tool estimates the risk of seizure recurrence and Chance of an Occurrence of a Seizure in the next Year (COSY) following antiseizure medication (ASM) withdrawal in adults with focal epilepsy.
This calculator provides data-driven predictions for individuals undergoing epilepsy surgery, incorporating key clinical, imaging, and pathological variables. The tool is designed to estimate outcomes over time using established longitudinal data from a cohort of 274 patients who underwent frontal lobe epilepsy surgery. These patients were followed up for a median period of 7.5 years, enabling the analysis of long-term surgical outcomes.
This tool estimates the risk of seizure recurrence and Chance of an Occurrence of a Seizure in the next Year (COSY) following frontal lobectomy surgery for tumor-related epilepsy. It is intended to support clinicians in assessing individualized recurrence risks and guiding postoperative care decisions for patients undergoing this procedure.
This tool estimates the risk of seizure recurrence and Chance of an Occurrence of a Seizure in the next Year (COSY) following frontal lobectomy surgery for refractory frontal lobe epilepsy.
This tool estimates the risk of seizure recurrence and Chance of an Occurrence of a Seizure in the next Year (COSY) following frontal lobe epilepsy surgery for drug-resistant frontal lobe epilepsy (FLE).
