Brain Imaging Critical for Diagnosing and Treating Wake-Up Strokes

Neurologists highlight that wake-up strokes account for 20% of ischaemic strokes, occurring during sleep and leaving doctors without a clear timeline for symptom onset.

Brain imaging scans such as immediate MRIs or CT angiograms help physicians assess brain injury extent and identify salvageable tissue for prompt treatment.

Patients arriving within 4.5 hours can undergo thrombolysis, while mechanical thrombectomy can be performed within 24 hours for large vessel occlusion cases.
