The "ABCD2" stroke score calculator is a calculator that calculates the risk of a person having a stroke in the days following a transient ischemic attack (TIA), which is defined as a brief stroke-like attack that, despite resolving within minutes to hours, still requires immediate medical attention to distinguish from an actual stroke In other words, it's a warning sign that a stroke may occur in the future. Therefore, a healthcare practitioner should assess the risk of the person actually having a stroke and take it seriously. The "ABCD" stroke score calculator helps to assess the risk of then person actually having a stroke once having a TIA.
So this calculator calculates the risk of a person having a stroke based on 5 criteria.
The "A" stands for age. If the person is younger than 60, this represents no risk (0 points). If the person is 60 or older, this represents a risk factor (1 point).
The "B" stands for blood pressure. If the blood pressure is less than 140/90, this represents no risk (0 points). If the blood pressure is greater than 140/90, this represents a risk factor (1 point).
The "C" stands for clinical features. If there is no speech disturbance and no unilateral weakness, this represents no risk (0 points). If there is speech disturbance, but no unilateral weakness, this represents a risk (1 point). If there is unilateral weakness, this represents an even greater risk (2 points).
There are 2 "D"s. One of the Ds stands for diabetes. If the person does not have diabetes, this represents no risk (0 points). If the person does have diabetes, this represents a risk factor (1 point).
The other "D" stands for duration of the transient ischemic attack (TIA). If the TIA lasted last than 10 minutes, this is a score of 0. If the TIA lasted between 10 and 59 minutes, this is a score of 1. If the TIA lasted greater than 60 minutes, this represents a score of 2.
The higher the score, the greater the chance of a person having a stroke. The "ABCD2" stroke scoring calculator can have a score ranging from 0 to 7.
A score of 1-3 represents a low risk for developing a stroke.
A score of 4-5 represents a moderate risk for developing a stroke.
A score of 6-7 represents a high risk for developing a stroke.
To use this calculator, a user simply enters in the patient's info, age, blood pressure, clinical features, diabetes status, and duration of the past TIA, and clicks the "Calculate" button. The score will automatically be calculated and displayed, along with what type of risk factor the score represents.
Below is a reference table summarizing the "ABCD2" scoring system.
