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.

Healthspan is more important than lifespan, so why don’t more people know about it?

 Has your competent? doctor taken on the responsibility of making sure your remaining years can be counted in your healthspan? That requires 100% recovery protocols. Does your doctor have them NO? So, you DON'T have a functioning stroke doctor, do you?

My healthspan was great until age 50 when my stroke occurred, probably about 8 years post stroke were not healthy until I got divorced and moved to Michigan. I now consider myself healthy enough to do anything I want to.

Healthspan is more important than lifespan, so why don’t more people know about it?

While more and more people are taking an interest in aging and lifespan, awareness on healthspan lags (Figure 2). If you don’t know what healthspan means you aren’t alone. What is healthspan?

Many might agree that “healthspan” can be defined as the period of one’s life that one is healthy. However, being “healthy” means different things to different people. A better definition might include being free from serious disease. A disease is considered to be serious if it is a leading cause of death (Table 1).1

Why do we care about healthspan? Caring about extending the well period of one’s life should be intuitive – if one is past their healthspan, it means they are chronically sick, often with a degenerating condition. Therefore, most people would agree that staying within their healthspan is desirable.

In an extreme case, Ezekiel Emmanuel, the brother of President Obama’s chief of staff Rahm Emmanuel, doesn’t want medical interventions past the age of 75.2 To paraphrase his argument, he only wants to live if he can live well.

Healthspan is a socioeconomic issue, too. There is a widening gap in life expectancy in different geographic regions of the US.3 Because lifespan and healthspan are intimately related, focusing on healthspan should help level the wellness playing field for more people.

What can we do about healthspan? First we need to measure it. Once we measure it, then we can improve it. While there are good biomarkers for a few of the serious diseases like heart disease, e.g., cholesterol levels, there aren’t good biomarkers for other leading causes of death, such as most cancers. Because we have trouble predicting whether someone may get a serious disease, how do we get a handle on healthspan?

Unlike average lifespan, which is now 79.3 years in the US, we don’t have a statistic to mark the end of the average healthspan. To address this, the World Health Organization (WHO) has developed an indicator, HALE – healthy life expectancy.4 A simple way to approximate HALE is to figure out the average age of the first occurrence of each of the most common serious diseases, determine their incidences, and then take the average of those two numbers (Table 1). This gives us 63.1 years old (which is close to the 2015 HALE estimate of 67.3 years old, Figure 1).

This means that we, on average, live up to 20% of our lives unhealthy. Needless to say, that is a long time.

To improve upon these statistics, we need treatments. Treatments don’t necessarily mean drugs, so let’s break them down into molecular and non-molecular approaches. First, there are many commonalities around lifestyle that could delay the onset of most, if not all, of the serious diseases. It might seem like common sense, but maintaining a healthy balanced diet with moderate, regular exercise and without smoking and drinking alcohol is the surest way to promote one’s healthspan and limit the onset of most diseases. The Mediterranean diet has fairly broad support in the literature.5

Regarding the molecular basis of healthspan, there is growing evidence on several dietary and cellular components that improve our body’s function. Fatty acids, energy “currencies” such as glucose and oxygen, and antioxidants such as NAD+ have been shown to influence the health of various tissues and their stem cells in many different species.6 Stem cells are interesting because they are important to tissue regeneration – a process directly involved in keeping our bodies healthy. Experimental treatments such as rapamycin and metformin, and dietary manipulations (e.g., caloric restriction, fasting mimicking) also have shown promise as longevity-promoting therapies. Still, it should be noted that many human clinical trials show conflicting results for the aging-preventing abilities of most natural or non-natural compounds (for clarification, see Notes below). Therefore, one should take caution in interpreting any study highlighting anything resembling a cure-all molecule.

Social, intellectual, and physical activities are also huge healthspan determinants.7 Even though they may be more commonly associated with psychological effects, their strong physiological effects should not be ignored. They should be treated by medical professionals as frontline approaches alongside medicines.

Healthspan is a topic relevant to all people with huge social and economic consequences around the world. While younger people might benefit most in the long-term from an increased focus on healthspan-moderating therapies, older adults might be first to see benefits. This is due to the simple fact that research involving older adults gets to the study outcome, either good or bad, faster. Therefore, to conclude with a plug for aging research, the time is now to get involved!
