Stroke Prognosis

* Stroke Type

  • Ischemic stroke: typically better prognosis, especially with early reperfusion.
  • Hemorrhagic stroke: higher early mortality, but better long-term recovery in survivors.

* Time to Treatment

  • Earlier treatment (thrombolysis/thrombectomy) improves outcome dramatically.
  • “Time is brain”: every minute of untreated large vessel occlusion leads to \~2 million neurons lost.

* Stroke Severity

  • NIHSS score >15 indicates poor short-term prognosis.
  • GCS <8 in hemorrhagic stroke indicates very poor prognosis.

* Lesion Location

  • Brainstem strokes are often severe due to cranial nerve and autonomic dysfunction.
  • Dominant hemisphere strokes carry risk of aphasia and cognitive deficits.

* Age and Frailty

  • Older age and low baseline functional status worsen prognosis.
  • Frailty independently predicts poor rehabilitation potential.

* Comorbidities

  • Atrial fibrillation, diabetes, hypertension, and prior stroke increase recurrence risk.
  • Cancer, dementia, and chronic kidney disease negatively affect recovery.

* Modified Rankin Scale (mRS) assesses functional independence. * NIH Stroke Scale (NIHSS) estimates stroke severity at onset. * ICH Score predicts mortality in intracerebral hemorrhage. * ASPECTS quantifies early ischemic changes on CT. * TOAST classification helps estimate recurrence based on stroke etiology.

* First 24–72 hours: critical for survival, especially in hemorrhagic stroke. * 1–4 weeks: edema resolves, early rehab begins. * 3–6 months: major recovery window for motor and language function. * 6–12 months: slower improvements in cognition and fine motor skills. * More than 1 year: plateau in most functional domains.

* Good recovery (mRS 0–2) is possible in about 40 to 50 percent of ischemic stroke patients with early intervention.

* Severe disability (mRS 4–5) occurs in about 25 to 30 percent of cases.

* Death:

  • Around 10 to 15 percent 30-day mortality in ischemic stroke
  • Around 40 to 60 percent in intracerebral hemorrhage

* Stroke recurrence:

  • 5 to 15 percent per year without optimal secondary prevention.

* Early stroke unit admission reduces mortality and disability. * Intensive multidisciplinary rehabilitation. * Rigorous secondary prevention including antiplatelets, anticoagulation (if atrial fibrillation), blood pressure and lipid control. * Treatment of depression and post-stroke fatigue. * Strong social and family support.


Among stroke patients, primary intracerebral hemorrhage (ICH) has the highest mortality rate.

Currently, cerebral stroke is considered to be one of the prior causes of high mortality, disability, and morbidity.

Stroke is a significant cardiovascular disease that influences the health of human beings all over the world, especially the elderly population.

Findings suggest a much larger contribution of healthcare access and quality (HAQ) to the younger mean age of stroke in low-middle income countries (LMICs), as compared with other potential factors. Additional studies on stroke care quality and accessibility are needed in LMICs 1).

A bursting inflammation has been observed that compromises neurologic function in patients who experience stroke.

Stroke causes lifelong disabilities where few therapeutic options are available. Using electrical and magnetic stimulation of the brain and physical rehabilitation, recovery of brain function can be enhanced even late after stroke.

Stroke center volumes significantly influence efficiency and outcomes in mechanical thrombectomy 2).


Higher BP within the first 24 hours after successful mechanical thrombectomy was associated with a higher likelihood of spontaneous intracerebral hemorrhage, mortality, and requiring hemicraniectomy 3).


Among young adults aged 18 to 49 years in the Netherlands who were 30-day survivors of first stroke, mortality risk compared with the general population remained elevated up to 15 years later 4).

In a randomized controlled trial, Liu Mei et al. from the *Zibo Central Hospital* (China) evaluated whether combining rehabilitation nursing with structured nutritional support could improve elderly stroke prognosis survivors. Published in the *Journal of Health Population and Nutrition* (2025), the study provides evidence that a combined intervention significantly enhances:

Methodological Strengths

  • Large sample (n=300); randomization supports internal validity
  • Multiple validated tools: NDS, MMSE, BI, FMA, biochemical & anthropometric measures
  • Ethical approval and informed consent ensured

Key Limitations

  • Lack of blinding → potential bias
  • Comparator ('standard care') vaguely described
  • No follow-up data: long-term effect unclear
  • No economic evaluation despite resource demands

Data & Reporting Concerns

  • Statistical methods underreported: no confidence intervals, unclear ITT vs PP
  • Baseline characteristics not shown
  • No subgroup analysis by age, stroke severity, or comorbidities
  • Score: 6/10
  • Promising evidence for combined rehab-nutrition in elderly stroke
  • However, methodological flaws and lack of sustainability data weaken generalizability

If your stroke unit considers integrating structured nutritional support into standard rehabilitation, weigh the benefits against:

A structured program with clear monitoring and follow-up protocols is essential for safe implementation.

A large RCT shows that combining rehab nursing with nutritional support boosts recovery metrics in elderly stroke patients. While short-term results are promising, lack of follow-up, cost data, and methodological transparency warrant cautious interpretation.
