Refractory Epilepsy Screening Tool for Lennox-Gastaut Syndrome (REST-LGS)

Description

Applies the REST-LGS screening logic to identify patients with refractory epilepsy who may have undiagnosed Lennox-Gastaut Syndrome (LGS). The tool assesses four key domains: Age of onset, Drug resistance, Cognitive impairment, and Specific seizure types associated with LGS.

Usage

rest_lgs_screen(onset_lt_9y, drug_resistant, cognitive_impairment,
                tonic_seizures, atonic_seizures, atypical_absence)

Arguments

onset_lt_9y	Numeric (0 or 1). Did the patient's seizures start before age 9? (1 = Yes).
drug_resistant	Numeric (0 or 1). Is the epilepsy drug-resistant (failed >= 2 anti-seizure medications)? (1 = Yes).
cognitive_impairment	Numeric (0 or 1). Does the patient have cognitive impairment or developmental delay? (1 = Yes).
tonic_seizures	Numeric (0 or 1). History or presence of tonic seizures (stiffening). (1 = Yes).
atonic_seizures	Numeric (0 or 1). History or presence of atonic seizures (drop attacks/head drops). (1 = Yes).
atypical_absence	Numeric (0 or 1). History or presence of atypical absence seizures (staring spells). (1 = Yes).

Value

A list containing:

Screening_Result	"Positive Screen" or "Negative Screen".
Recommendation	Clinical guidance based on the screening result.
