Brain, nerves & mind

Stroke: 4.5 hours and 24 hours

“Nothing can be done, sleep on it” is a leading avoidable cause of stroke disability. Two time windows decide everything.

  1. 1IV thrombolysis: within 3 h OR 1.75, 3–4.5 h OR 1.26, beyond 4.5 h no significant benefit (6,756-patient meta-analysis)
  2. 2Benefit holds regardless of age or severity — including over 80
  3. 3Thrombectomy (large-vessel occlusion): independence 46% vs 26.5%; treat 2.6 to reduce disability in 1
  4. 4Selected patients can be treated up to 24 h — but only imaging in hospital can tell
  5. 5Every minute of delay costs about 1.9 million neurons
  6. 6Don’t drive yourself, don’t take pills first, don’t wait for family

Kidney patients especially: emergency imaging tells ischaemic from bleed; thrombolysis and thrombectomy are not contraindicated in CKD.

“Nothing can be done, sleep on it” is a leading avoidable cause of stroke disability. Two time windows decide everything.

1. IV thrombolysis: within 3 h OR 1.75, 3–4.5 h OR 1.26, beyond 4.5 h no significant benefit (6,756-patient meta-analysis)
2. Benefit holds regardless of age or severity — including over 80
3. Thrombectomy (large-vessel occlusion): independence 46% vs 26.5%; treat 2.6 to reduce disability in 1
4. Selected patients can be treated up to 24 h — but only imaging in hospital can tell
5. Every minute of delay costs about 1.9 million neurons
6. Don’t drive yourself, don’t take pills first, don’t wait for family

Kidney patients especially: emergency imaging tells ischaemic from bleed; thrombolysis and thrombectomy are not contraindicated in CKD.

0–5StopwatchA stroke — watch overnight and see?
5–254.5-hour hourglassNine trials, 6,756 people: clot-buster within 3 hours raises the odds of no disability by 75%; after 4.5 hours the benefit is gone.
25–4546% vs 26.5%Thrombectomy for large-vessel occlusion: independence rises from 26.5% to 46% — fewer than 3 treated to help 1.
45–60Emergency numberEvery minute costs 1.9 million neurons. Note the time, call emergency services. Kidney patients too — these treatments are not off-limits.
