 | | Prognosis |
Death
Many patients die b though the risk is lower with a minor stroke or
TIA.
a
The risk of dying following a stroke is increased with:
b
-
increasing age
-
drowsy or comatose at first examination
-
fever or hypothermia on admission
-
an elevated glucose on admission particularly if no known diabetes mellitus
The risk of dying after 30 days is increased with
a
-
a previous TIA
-
pre-stroke functional disability
- a history of intermittent claudication
-
urinary incontinence
The risk of dying following an
ischaemic
stroke is increased with:
-
increasing age a b
-
a severe a or worsening stroke b
-
atrial fibrillation a b
-
ischaemic
heart disease (particularly if an early onset)
b or intermittent claudication b
-
smoking a
-
heart failure b
-
an elevated glucose on admission a
-
an elevated CRP (> 33 mg/dl) on admission a
-
urinary incontinence b
-
unpartnered marital status b
Use the following clinical prediction rule to determine your patient's
risk of dying from an ischaemic stroke within 30 days. b
Score your patient for the following features

| body temperature < 36.5°C |

The risk of dying following a TIA or minor stroke is increased with:
a
-
increasing age a
-
diabetes mellitus a
-
atrial fibrillation a
-
ischaemic
heart disease a or intermittent claudication
a
-
hypercholesterolaemia a
-
minor disability a, including dysarthria a,
cranial nerve palsy a or limb weakness a
-
seizures in hospital, or altered consciousness a
-
intraventricular
haemorrhage a
-
vomiting a
The risk of dying from an intracranial
haemorrhage
is increased with:
a
-
ventricular extension
-
intracerebral
haemorrhage
volume ≥ 30 cm³
-
an initial GCS < 12
Deterioration
Many patients with stroke will get worse over the next few days
b
The risk of early deterioration is increased with:
b
-
posterior circulation stroke
-
reduced level of consciousness
-
hypertension
The risk of early deterioration following an
ischaemic
stroke is increased with a
-
high systolic blood pressure at admission
-
carotid vascular territory involvement
-
elevated initial
glycaemia
The risk of early deterioration following an intracranial
haemorrhage
is increased with
a
-
ventricular extension
-
intracerebral haemorrhage volume ≥ 30 cm³
Functional outcome
Patients with more severe strokes are less likely to be functionally independent
a
Patients are less likely to have a good function outcome with:
-
increasing age a
b
-
atrial fibrillation a
-
a severe deficit a
b
-
bilateral or right-sided-stroke b
-
urinary incontinence a
b
-
dysphagia b
-
pre-stroke institutionalisation a
-
no committed caregiver
b
Nonetheless many patients return to work
b
Patients are more likely to return to work if they have:
b
-
no apraxia
-
normal muscle strength
-
a desk job
Dementia
Many patients will develop dementia
b
Depression
Watch out for depression
b
The risk of depression is increased with increasing age, and reduced with an active rehabilitation program.
b
Dysphagia
Swallowing problems are common.
a
A delayed or absent swallowing reflex on admission increases the risk of continued swallowing problems, a chest infection or aspiration.
a
Dysphagia, chest infection or aspiration are more likely with:
a
-
penetration of food
-
delayed oral transit
-
increasing age
-
male sex
Recurrence
Recurrent strokes are common a b though the risk is lower for patients with a TIA or minor stroke.
a
The risk of recurrence is increased following an
ischaemic
stroke with:
a
-
increasing age b
-
a prior stroke a
-
diabetes mellitus a b or elevated glucose levels on admission a
-
hypertension at discharge a
-
heavy alcohol use a
-
a patent foramen ovale and atrial septal aneurysm
a
The risk of a recurrent stroke following a TIA or minor stroke is increased with:
- increasing age a
- recurrent minor strokes or a lacunar stroke a
- diabetes mellitus a
- hypertension a
- a prior MI a
Seizures
Watch out for seizures within the first few days
a
The risk is increased with:
-
a cortical involvement
b
-
an acute agitated confusional state b
-
an anterior hemisphere infarct b
A few patients will go on to have late seizures
b
The risk of seizures is increased with:
-
a
haemorrhagic
first stroke
b
-
seizure onset within 24 hours of stroke
b
-
recurrent stroke b
The risk of status epilepticus is increased with
- a poor functional status b

Urinary incontinence
Urinary incontinence is common initially, but settles in most patients.
a
The risk is increased with
a
- old age
- a subarachnoid haemorrhage
- dysphagia
- visual field defect
- motor weakness
and reduced following a lacunar infarct.
