Prognosis

Recurrent strokes are common ^{a b} though the risk is lower for patients with a TIA or minor stroke. ^a

Note:

• A fifth of patients with a first stroke will have another within 5 years (20%: 95% CI: 17% to 23%) ^b
• 10% of patients with an ischaemic stroke will have another stroke within 13 months (95% CI: 8.5% to 12%). ^a 22% will have had another stroke at 5 years (95% CI: 18% to 27%) a ^b
• 12% of patients with a minor stroke will have a major stroke within 10 years (95% CI: 8% to 15%). ^a 27% of patients will have a recurrent stroke or die within 2 years (95% CI: 20% to 34%). ^a
• One in thirty patients aged 15 to 44 with a first stroke or TIA have another within 8 years (3.0%: 95% CI: 1.2% to 4.9%). ^b

Stroke subtypes help predict risk of recurrent stroke

Stroke subtype a	recurrent stroke at 1 year
LACI	9%  (4% to 14%)
PACI	6%  (2% to 12%)
PACI	17%  (12% to 23%)
POCI	20%  (13% to 27%)

The cause of stroke can help predict recurrent stroke 

Presumed cause a	recurrent stroke at 5 years
atherosclerosis	40% (28% to 55%)
cardioembolic	32% (18% to 47%)
lacunar	25% (14% to 39%)
unknown	33% (24% to 42%)
