1. A documented 33% dementia chance post-stroke from an Australian study? May 2012.
2. Then this study came out and seems to have a range from 17-66%. December 2013.
3. A 20% chance in this research. July 2013.
Does your doctor have ANY prevention protocols? 4.5 years and still nothing? What the hell has your doctor been doing in those years?

Abstract
Background and Purpose—Stroke
is a risk factor for dementia, but the risk of dementia after different
stroke types is poorly understood. We examined the long-term risk of
dementia among survivors of any first-time stroke and of first-time
ischemic stroke, intracerebral hemorrhage, and subarachnoid hemorrhage.
Methods—We
conducted a 30-year nationwide population-based cohort study using data
from Danish medical databases (1982–2013) covering all Danish
hospitals. We identified 84 220 ischemic stroke survivors, 16 723
intracerebral hemorrhage survivors, 9872 subarachnoid hemorrhage
survivors, and 104 303 survivors of unspecified stroke types. Patients
were aged ≥18 years and survived for at least 3 months after diagnosis.
We formed a comparison cohort from the general population (1 075 588
patients without stroke, matched to stroke patients by age and sex). We
computed absolute risks and hazard ratios of dementia up to 30 years
after stroke.
Results—The
30-year absolute risk of dementia among stroke survivors was 11.5% (95%
confidence interval, 11.2%–11.7%). Compared with the general
population, the hazard ratio (95% confidence interval) for dementia
among stroke survivors was 1.80 (1.77–1.84) after any stroke, 1.72
(1.66–1.77) after ischemic stroke, 2.70 (2.53–2.89) after intracerebral
hemorrhage, and 2.74 (2.45–3.06) after subarachnoid hemorrhage. Younger
patients regardless of stroke type faced higher risks of poststroke
dementia than older patients. The pattern of hazard ratios by stroke
type did not change during follow-up and was not altered appreciably by
age, sex, or preexisting diagnoses of vascular conditions.
Conclusions—Stroke
increases dementia risk. Survivors of intracerebral hemorrhage and
subarachnoid hemorrhage are at particularly high long-term risk of
poststroke dementia.
