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.

Parkinson's disease is not one, but two diseases

It is your doctor's responsibility to have protocols that prevent either one because of your chance of getting Parkinsons post stroke. S/he has only had 3.5 years to figure out a prevention protocol. That is their job, isn't it?

YOUR DOCTOR'S RESPONSIBILITY!

Parkinson's disease is not one, but two diseases

Although the name may suggest otherwise, Parkinson's disease is not one but two diseases, starting either in the brain or in the intestines. Which explains why patients with Parkinson's describe widely differing symptoms, and points towards personalized medicine as the way forward for people with Parkinson's disease.

This is the conclusion of a study which has just been published in the leading neurology journal Brain.

The researchers behind the study are Professor Per Borghammer and Medical Doctor Jacob Horsager from the Department of Clinical Medicine at Aarhus University and Aarhus University Hospital, Denmark.

"With the help of advanced scanning techniques, we've shown that Parkinson's disease can be divided into two variants, which start in different places in the body. For some patients, the disease starts in the intestines and spreads from there to the brain through neural connections. For others, the disease starts in the brain and spreads to the intestines and other organs such as the heart," explains Per Borghammer.


He also points out that the discovery could be very significant for the treatment of Parkinson's disease in the future, as this ought to be based on the individual patient's disease pattern.

Parkinson's disease is characterized by slow deterioration of the brain due to accumulated alpha-synuclein, a protein that damages nerve cells. This leads to the slow, stiff movements which many people associate with the disease.

In the study, the researchers have used advanced PET and MRI imaging techniques to examine people with Parkinson's disease. People who have not yet been diagnosed but have a high risk of developing the disease are also included in the study. People diagnosed with REM sleep behavior syndrome have an increased risk of developing Parkinson's disease.

The study showed that some patients had damage to the brain's dopamine system before damage in the intestines and heart occurred. In other patients, scans revealed damage to the nervous systems of the intestines and heart before the damage in the brain's dopamine system was visible.

This knowledge is important and it challenges the understanding of Parkinson's disease that has been prevalent until now, says Per Borghammer.

"Until now, many people have viewed the disease as relatively homogeneous and defined it based on the classical movement disorders. But at the same time, we've been puzzled about why there was such a big difference between patient symptoms. With this new knowledge, the different symptoms make more sense and this is also the perspective in which future research should be viewed," he says.

The researchers refer to the two types of Parkinson's disease as body-first and brain-first. In the case of body-first, it may be particularly interesting to study the composition of bacteria in the intestines known as the microbiota.


"It has long since been demonstrated that Parkinson's patients have a different microbiome in the intestines than healthy people, without us truly understanding the significance of this. Now that we're able to identify the two types of Parkinson's disease, we can examine the risk factors and possible genetic factors that may be different for the two types. The next step is to examine whether, for example, body-first Parkinson's disease can be treated by treating the intestines with feces transplantation or in other ways that affect the microbiome," says Per Borghammer.

"The discovery of brain-first Parkinson's is a bigger challenge. This variant of the disease is probably relatively symptom-free until the movement disorder symptoms appear and the patient is diagnosed with Parkinson's. By then the patient has already lost more than half of the dopamine system, and it will therefore be more difficult to find patients early enough to be able to slow the disease," says Per Borghammer.

The study from Aarhus University is longitudinal, i.e. the participants are called in again after three and six years so that all of the examinations and scans can be repeated. According to Per Borghammer, this makes the study the most comprehensive ever, and it provides researchers with valuable knowledge and clarification about Parkinson's disease—or diseases.

"Previous studies have indicated that there could be more than one type of Parkinson's, but this has not been demonstrated clearly until this study, which was specifically designed to clarify this question. We now have knowledge that offers hope for better and more targeted treatment of people who are affected by Parkinson's disease in the future," says Per Borghammer.

According to the Danish Parkinson's Disease Association, there are 8,000 people with Parkinson's disease in Denmark and up to eight million diagnosed patients worldwide.

This figure is expected to increase to 15 million in 2050 due to the aging population, as the risk of getting Parkinson's disease increases dramatically the older the population becomes.
