Which emergency condition is a differential diagnosis for a stroke?

A complicated migraine can present with neurological symptoms that closely mimic those of a stroke, making it a significant differential diagnosis. Symptoms such as unilateral weakness, slurred speech, and visual disturbances can occur during a severe migraine attack, particularly in the case of a complicated migraine, which may include aura or other neurological deficits.

This overlap in symptoms makes it essential for healthcare professionals, including paramedics, to differentiate between a stroke and a complicated migraine during assessment. Recognizing the differences in symptom onset, duration, and accompanying features typical of migraines versus strokes is crucial for accurate diagnosis and treatment.

In contrast, the other options do not typically present with neurological symptoms similar to a stroke. Gastroenteritis primarily involves gastrointestinal symptoms and does not affect neurological function in the same way. A fractured limb usually presents with pain, swelling, and deformity but does not cause the neurological deficits associated with strokes. Cardiac arrest leads to loss of consciousness and respiratory failure rather than focal neurological deficits.
