How do you test for hemineglect?
In this test, a line a few inches long is drawn on a piece of paper and the patient is then asked to dissect the line at the midpoint. Patients exhibiting, for example, left-sided neglect will exhibit a rightward deviation of the line’s true midpoint. Another widely used test is the line cancellation test.
How do you test for extinction?

What causes hemineglect?
Experts believe hemineglect occurs only when specific areas of the brain are damaged by a stroke. For example, the parietal lobe in the right hemisphere of the brain is involved with awareness of the space on both sides of the body, while the left parietal lobe only governs the right side.
What does extinction mean in stroke?
Extinction is a behavioural symptom of brain lesions where patients report, respond, or orient to a stimulus presented on the contralesional side, but fail to detect the same stimulus when presented concurrently with another stimulus on the ipsilesional side (Bender 1952; Chechlacz et al.
