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.

Lowering LDL Cholesterol Linked to 25% Lower Stroke Risk

 If your doctor doesn't address this immediately; s/he is FUCKING INCOMPETENT? No excuses!

Send me personal hate mail on this: oc1dean@gmail.com. I'll print your complete statement with your name(If you can't stand by your name don't bother replying anonymously) and my response in my blog. Or are you afraid to engage with my stroke-addled mind? No excuses are allowed! You're medically trained; it should be simple to precisely state EXACTLY WHY you aren't working on 100% recovery protocols with NO EXCUSES!

I take no prisoners in trying to get stroke solved! No knowledge of all of this and you have blithering idiots in charge, how long before you fire all of them? 

The latest here:

Lowering LDL Cholesterol Linked to 25% Lower Stroke Risk

NEW ORLEANS — Lowering low-density lipoprotein (LDL) cholesterol level to < 40 mg/dL — well beneath current post-stroke guideline targets — reduced major cardiovascular events without increasing hemorrhagic stroke risk in patients with prior ischemic stroke.

Results from the FOURIER study, which included more than 5000 patients, showed that individuals with LDL levels < 40 mg/dL had a 31% lower rate of major adverse cardiovascular events (MACEs) — including stroke, cardiovascular death, myocardial infarction, hospitalization for unstable angina, and coronary revascularization — than patients whose LDL levels were ≥ 70 mg/dL. Those with LDL levels < 40 mg/dL also experienced a 27% reduction in all strokes and a 25% reduction in subsequent ischemic strokes.

Incidence of the composite endpoint and the individual outcomes of all stroke and ischemic stroke also decreased in a stepwise manner as LDL levels decreased.

In addition, there was no association between occurrence of hemorrhagic stroke and lower LDL levels, in contrast with what some prior studies have suggested.

“The main finding is that the lower the achieved LDL in this population, the better the cardiovascular outcome; there didn’t appear to be a floor to the effect,” senior investigator Robert P. Giugliano, MD, with the TIMI Study Group at the Brigham and Women’s Hospital and professor at the Harvard Medical School, both in Boston, told Medscape Medical News.“And no matter what LDL level patients achieved, there was really no difference in safety endpoints,” he added.

Giugliano believes the results could be practice changing. “I am already advocating to my patients with ischemic stroke that we try to get the LDL down very low, if at all possible,” he said.

The findings were presented on November 8 at the American Heart Association (AHA) Scientific Sessions 2025 and were published online on November 3 in Circulation.

An Ongoing Debate

Although patients with a history of ischemic stroke are at an increased risk for recurrence and other MACEs, debate continues over the benefits and potential safety concerns of intensive LDL lowering — and just how low is too low.

A guidance paper on the management of blood cholesterol was issued 7 years ago by the AHA, the American College of Cardiology (ACC), and 10 other organizations. The 2018 AHA/ACC/multi-society guidelines discussed an LDL threshold of 70 mg/dL in high-risk individuals.

As reported at the time by Medscape Medical News,guidelines released in 2019 from the European Society of Cardiology(ESC) and European Atherosclerosis Society suggested an LDL of < 55 mg/dL in very high-risk patients, defined as those with conditions such as atherosclerotic cardiovascular disease (ASCVD). The ESC released updated guidance in August of this year.

Although some earlier studies — including certain statin trials and a 2019 analysis in patients without prior stroke or myocardial infarction — have linked very low LDL levels to a higher risk for hemorrhagic stroke, other research has indicated that intensive LDL lowering can be safe, at least in specific patient populations.

The current investigators aimed to evaluate the effects of intensive LDL lowering specifically in patients with a history of ischemic stroke, excluding those who had experienced a stroke within the previous 30 days.

The original multinational FOURIER randomized controlled trial enrolled more than 27,000 patients with stable ASCVD to compare the PCSK9 inhibitor evolocumab with placebo, with initial results published in 2017. FOURIER-OLE was an open-label extension of the original study.

For the current analysis, the investigators analyzed data of 5291 FOURIER and FOURIER-OLE participants (mean age, 65 years; 66% men) with a prior ischemic stroke over an average of 7-8 years. The primary endpoint was the composite of the five MACE conditions.

A Reasonable Target?

At the end of follow-up, 40.1% of participants achieved LDL of ≥ 70 mg/dL — while 9.6% achieved 55 to < 70 mg/dL, 11.1% achieved 40 to < 55 mg/dL, 26.6% achieved 20 to < 40 mg/dL, and 12.6% achieved < 20 mg/dL.

Lower LDL levels to < 40 mg/dL had a “monotonic relationship” with lower adjusted annualized incidence rates of the composite primary endpoint (P for trend < .001) and all stroke and recurrent ischemic stroke (P for trend = .002 for both).

Adjusted incidence rate ratios for the composite primary endpoint, all stroke, and ischemic stroke for those with LDL levels < 40 mg/dL vs those with levels ≥ 70 mg/dL were 0.69, 0.73, and 0.75, respectively.

Hemorrhagic strokes “were infrequent and unrelated” to achieved LDL level (P for trend = .85), the researchers noted.

“These findings support the concept that more intensive [LDL] lowering in patients with prior ischemic stroke may be warranted,” they wrote, adding that a level below 40 mg/dL may represent “a reasonable target.”

The investigators noted that more randomized controlled trials are now needed to definitively determine optimal LDL goals in this patient population.

Lower Is Better

Commenting on the study for Medscape Medical News, Laurence Sperling, MD, Katz professor in preventive cardiology at the Emory University School of Medicine and founder of the Emory Center for Heart Disease Prevention in Atlanta, said the findings are particularly important given the ongoing questions and concerns about this issue within both the medical and patient communities.

“This was a well-designed study with the right population in which to examine these questions. And I think it’s strong on both ends. In showing that lower [LDL] is better for cardiovascular disease risk reduction in high-risk individuals and that lower appears to be safe,” Sperling said.

He added that the trial had a “higher strength of evidence” than some previous observational or epidemiologic studies that suggested increased risk for adverse events. “Although we can’t use a single study to be definitive,” it follows along with several recent trials that have shown no signals of increased risk for hemorrhagic stroke, he said.

Sperling, who was not involved with the research, was on the writing committee of the 2018 AHA/ACC/Multi-Organization Guideline on the Management of Blood Cholesterol.

He noted that an update to that guideline is currently in progress and estimated that it will be released sometime in 2026.

Systematic analysis of the burden of ischemic stroke attributable to high LDL-C from 1990 to 2021

 Useful research would be to create EXACT protocols that lower LDL-C and thus prevent strokes.  If competent mentors and senior researchers existed, then we would have useful research! But alas, they don't exist! Everything in stroke is a shitshow! Your best bet is to not have a stroke!

Systematic analysis of the burden of ischemic stroke attributable to high LDL-C from 1990 to 2021

Background: Low-density lipoprotein cholesterol (LDL-C) is a public health concern linked to ischemic stroke. The study aimed to describe the epidemiological characteristics of ischemic stroke attributable to high LDL-C from 1990 to 2021.

Methods: In this study, we analyzed data from the Global Burden of Disease 2021 to present trends in ischemic stroke related to high LDL-C over the past 30 years. The relationship between disease burden and the Socio-Demographic Index (SDI) was examined. To assess international health disparities, we applied the Slope Index of Inequality (SII) and the Concentration Index (CI). Furthermore, we conducted a frontier analysis to identify areas for improvement and developmental gaps among nations, and employed the Bayesian Age-Period-Cohort (BAPC) model to forecast the disease burden for the next 15 years.

Results: In 2021, the incidence of ischemic stroke attributed to high LDL-C significantly increased compared to 1990, with a more pronounced growth rate in males. The burden mainly affects individuals aged 70 to 84. Analysis using the age-period-cohort model indicates that mortality rates and DALYs rise with age, while period and cohort effects exhibit a gradual decline. Across different SDI regions, trends generally follow a similar downward path, with a narrowing gap in disease burden among regions with varying SDI levels. However, the disease burden in high SDI countries remains significant, indicating potential for reduction. Predictions for the next 15 years suggest that while the global disease burden will decrease, there may be an increase among individuals under 55.

Conclusion: Compared to 1990, the overall age-standardized burden of ischemic stroke related to high LDL-C has been controlled. However, disparities persist across different SDI regions. We have observed an increasing burden among younger populations. Consequently, countries and regions must adopt new measures tailored to their SDI levels, with a specific emphasis on younger individuals. It is essential to develop prevention and treatment strategies aimed at high-risk groups.

1 Introduction

Ischemic stroke represents a serious global health challenge, ranking among the top causes of long-term disability and mortality worldwide (1). Historically, ischemic stroke has been a significant contributor to overall disease burden, with notable shifts in its epidemiology over the past three decades. From 1990 to 2021, the disease burden showed a declining trend, with the average annual percent change (AAPC) in the age-standardized incidence rate (ASIR), mortality rate (ASMR), and disability-adjusted life years (ASDR) for ischemic stroke being −0.57 (95% CI: −0.66 to −0.48), −1.60 (95% CI: −1.81 to −1.39), and −1.37 (95% CI: −1.53 to −1.20), respectively (2). Over these 30 years, the burden of ischemic stroke attributable to metabolic risks, environmental and occupational risks, and behavioral risks all showed a declining trend. Among these, metabolic-related factors remained the primary risk factors for ischemic stroke, with a population attributable fraction (PAF) of 76.88% (2). Among these, high low-density lipoprotein (LDL) cholesterol had a PAF of 25.78%, making it a significant cause of ischemic stroke among metabolic factors, second only to high systolic blood pressure (2).

Although the age-standardized disease burden of ischemic stroke has decreased, there were still 7,804,449 cases of ischemic stroke globally in 2021 (95% UI, 6,719,760–8,943,692), imposing a significant economic burden on public health systems (2). Additionally, due to more advanced medical facilities in developed countries and regions compared to the poorer infrastructure and medical conditions in developing and underdeveloped areas, there are significant disparities in disease burden across different regions. Furthermore, there are differences in disease burden across different age groups and genders. Therefore, a more detailed analysis of the disease burden related to ischemic stroke risk factors is still necessary, which may provide new insights for reducing this burden.

Hyperlipidemia, particularly low-density lipoprotein cholesterol (LDL-C), is a well-established risk factor for cardiovascular disease and a key driver of ischemic stroke (3–6). Among ischemic stroke cases, high LDL cholesterol (LDL-C) has a population attributable fraction (PAF) of 25.78%, making it a significant cause of ischemic stroke among metabolic factors, second only to high systolic blood pressure (2). Through lipid-lowering drug interventions, dyslipidemia is a modifiable risk factor for ischemic stroke, and its control can prevent the occurrence and recurrence of stroke. Studies have shown that actively lowering cholesterol levels with high doses of atorvastatin can reduce the incidence of stroke by 33% and recurrent stroke by 16% in patients with carotid artery stenosis (7).

Despite ongoing interventions to manage cholesterol levels, the efficacy of these efforts in reducing ischemic stroke burden due to high LDL-C remains uncertain (8). In a study involving 213,380 individuals, only 51.8% of very high-risk (VHR) patients with atherosclerotic cardiovascular disease (ASCVD) and type 2 diabetes (DM2) achieved the lipid-lowering target (LDL-C < 70 mg/dl) (9). As economic development progresses, high-energy, high-cholesterol, and high-fat diets are becoming more common among people, coupled with a lack of exercise and increased life stress, which may further increase the burden of ischemic stroke due to dyslipidemia.

To further assess the disease burden of ischemic stroke caused by dyslipidemia, this study utilizes GBD 2021 data to explore the long-term trends, regional disparities, and future projections of ischemic stroke burden related to high LDL-C from 1990 to 2021. By providing these insights, we aim to assist healthcare professionals and policymakers in developing effective strategies to mitigate the health risks and burden associated with ischemic stroke.

Low- and High-Density Lipoprotein Cholesterol and Dementia Risk Over 17 Years of Follow-up Among Members of a Large Health Care Plan

I have no clue what my levels were or currently are and I don't ever plan on worrying about them.

Low- and High-Density Lipoprotein Cholesterol and Dementia Risk Over 17 Years of Follow-up Among Members of a Large Health Care Plan

Abstract

Background and Objectives: The associations of high- and low-density lipoprotein cholesterol (HDL-C and LDL-C) with dementia risk in later life may be complex, and few studies have sufficient data to model non-linearities or adequately adjust for statin use. We evaluated the observational associations of HDL-C and LDL-C with incident dementia in a large and well-characterized cohort with linked survey and electronic health record (EHR) data.

Methods: Kaiser Permanente Northern California health plan members aged 55 years and older who completed a health behavior survey between 2002 and 2007, had no history of dementia prior to the survey, and had laboratory measurements of cholesterol within two years after survey completion were followed through December 2020 for incident dementia (Alzheimer’s Disease Related Dementia [ADRD]; Alzheimer’s, vascular, and/or non-specific dementia) based on ICD9 or ICD10 codes in EHRs. We used Cox models for incident dementia with follow-up time beginning 2 years post-survey (after cholesterol measurement) and censoring at end of membership, death, or end of study period. We evaluated non-linearities using b-splines, adjusted for demographic, clinical, and survey confounders, and tested for effect modification by baseline age or prior statin use.

Results: 184,367 participants [mean age at survey of 69.5 years, mean HDL-C=53.7 mg/dL (SD = 15.0), LDL-C=108 mg/dL (SD = 30.6)] were included. Higher and lower HDL-C values were associated with elevated ADRD risk compared to the middle quantile: HDL-C in the lowest quintile was associated with an HR of 1.07 (95% CI: 1.03-1.11) and HDL-C in the highest quintile was associated with an HR of 1.15 (95% CI: 1.11-1.20). LDL-C was not associated with dementia risk overall, but statin use qualitatively modified the association. Higher LDL-C was associated with slightly greater risk of ADRD for statin users (53% of the sample, HR per 10 mg/dL increase=1.01, 95% CI: 1.01-1.02) and lower risk for non-users (HR per 10 mg/dL increase=0.98; 95% CI: 0.97-0.99). There was evidence for effect modification by age with linear HDL-C (p=0.003) but not LDL-C (p=0.59).

Discussion: Both low and high levels of HDL-C were associated with elevated dementia risk. The association between LDL-C and dementia risk was modest.
