FACE-DROPS Score for Stroke Risk

Description

Calculates the FACE-DROPS score to assess the likelihood of acute stroke versus stroke mimics. This tool evaluates facial weakness, arm weakness, speech impairment, eye deviation, duration/onset, prior history, and seizure activity (which often suggests a mimic).

Usage

face_drops_stroke_score(facial_droop, arm_drift, communication_speech,
                        eye_deviation, duration_sudden, recurrence_or_prior,
                        onset_seizure, seizure_history, age)

Arguments

facial_droop	Numeric (0 or 1). Presence of facial droop or asymmetry. (1 = Yes).
arm_drift	Numeric (0 or 1). Presence of arm drift or weakness. (1 = Yes).
communication_speech	Numeric (0 or 1). Presence of speech disturbance or confusion. (1 = Yes).
eye_deviation	Numeric (0 or 1). Presence of gaze deviation. (1 = Yes).
duration_sudden	Numeric (0 or 1). Sudden onset of symptoms consistent with vascular event. (1 = Yes).
recurrence_or_prior	Numeric (0 or 1). History of prior stroke or vascular disease. (1 = Yes).
onset_seizure	Numeric (0 or 1). Seizure activity at onset. (1 = Yes). Note: This typically subtracts from the stroke likelihood.
seizure_history	Numeric (0 or 1). Known history of epilepsy or seizures. (1 = Yes).
age	Numeric. Patient age in years.

Value

A list containing:

Score	The calculated score.
Interpretation	Clinical interpretation guidance (Likely Stroke vs. Mimic).

Examples

# Example 1: High Probability
# Face(1), Arm(1), Speech(1), Sudden(1), No Seizure(0), Age 70
face_drops_stroke_score(1, 1, 1, 0, 1, 1, 0, 0, 70)

# Example 2: Potential Mimic
# Seizure at onset(1), History of Seizures(1), Age 30
face_drops_stroke_score(0, 0, 0, 0, 1, 0, 1, 1, 30)
