Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

Prevalence and Clinical Correlates of Intracranial Dolichoectasia in Individuals With Ischemic Stroke

If you have  intracranial dolichoectasia ask your doctor how to prevent strokes because this tells us nothing on how to prevent a stroke.

Prevalence and Clinical Correlates of Intracranial Dolichoectasia in Individuals With Ischemic Stroke

Originally publishedhttps://doi.org/10.1161/STROKEAHA.120.032225Stroke. 2021;52:2311–2318

Background and Purpose:

Acute ischemic stroke is a known complication of intracranial dolichoectasia (IDE). However, the frequency of IDE causing brain infarction is unknown. We aim to determine the prevalence and clinical correlates of IDE in acute ischemic stroke by employing an objective IDE definition for major intracranial arteries of the anterior and posterior circulation.

Methods:

Consecutive patients with acute ischemic stroke admitted to a tertiary-care hospital during a 4-month period were analyzed. Intracranial arterial diameter, length, and tortuosity were determined by semiautomatic vessel segmentation and considered abnormal if ≥2 SDs from the study population mean. Either ectasia (increased diameter) or dolichosis (increased length or tortuosity) of at least one proximal intracranial artery defined IDE. Symptomatic IDE was considered when the infarct was located in the territory supplied by an affected artery in the absence of any alternative pathogenic explanation. Multivariate models were fitted to determine IDE clinical correlates.

Results:

Among 211 cases screened, 200 patients (mean age 67±14 years, 47.5% men) with available intracranial vessel imaging were included. IDE was identified in 24% cases (5% with isolated ectasia, 9.5% with isolated dolichosis, and 9.5% with both ectasia and dolichosis). IDE was considered the most likely pathogenic mechanism in 12 cases (6% of the entire cohort), which represented 23.5% of strokes initially categorized as undetermined cause. In addition, 21% of small-artery occlusion strokes had the infarct territory supplied by a dolichoectatic vessel (3% of the entire cohort). IDE was independently associated with male sex (odds ratio, 4.2 [95% CI, 1.7–10.6]) and its component of ectasia was associated with advanced age (odds ratio, 3.5 [95% CI, 1.3–9.5]). Vascular risk profile was similar across patients with stroke with and without IDE.

Conclusions:

Our findings suggest that IDE is an arteriopathy frequently found in patients with acute ischemic stroke and is likely responsible for a sizable fraction of strokes initially categorized as of undetermined cause and perhaps also in those with small-artery occlusion.
