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.

Selenium-containing compounds: a new hope for innovative treatments in Alzheimer’s disease and Parkinson’s disease

 Didn't your competent? doctor start  have you getting selenium  a long time ago?

Somehow I doubt your doctor and hospital has done one damn thing with this in 9 years and won't do a damn thing now.  Don't do anything with this until your doctor prescribes it. Will this selenium lower the risk of Parkinsons and Alzheimers? Why doesn't you doctor know the answer to that easy question?

Taken at normal doses, selenium does not usually have side effects. An overdose of selenium may cause bad breath, fever, and nausea, as well as liver, kidney and heart problems and other symptoms. At high enough levels, selenium could cause death.

Highlights

  • The latest research breakthroughs in Alzheimer’s disease and Parkinson’s disease.

  • Critical discussion of the role of selenium in neurodegeneration.

  • Recent advances in organoselenium compounds for neurological disorders.

Abstract

Neurodegenerative diseases are challenging to cure. To date, no cure has been found for Alzheimer’s disease or Parkinson’s disease, and current treatments are able only to slow the progression of the diseases and manage their symptoms. After an introduction to the complex biology of these diseases, we discuss the beneficial effect of selenium-containing agents, which show neuroprotective effects in vitro or in vivo. Indeed, selenium is an essential trace element that is being incorporated into innovative organoselenium compounds, which can improve outcomes in rodent or even primate models with neurological deficits. Herein, we critically discuss recent findings in the field of selenium-based applications in neurological disorders.

Introduction

Selenium and seleno-compounds have been largely studied in diseases with distinct aetiologies and development stages, such as cancer and neurodegenerative diseases [1], [2], [3], [4], [5], [6]. With regards to the latter group, considerable research efforts are ongoing, driven by the hope of obtaining therapeutics that are less toxic and more effective than current treatments. Selenium has been reported to exert diametral effects on the central nervous system (CNS), showing both toxic and protective properties [7], [8]. Thus, several groups have focused on different strategies to incorporate selenium into bioactive compounds and small molecules [9].

Over the past 40 years, evidence in the scientific literature has demonstrated that small selenium-containing compounds represent good candidates in drug discovery, particularly because of their ability to counteract cancer development and cellular oxidation [10]. The design, synthesis and testing of bioactive molecules has grown exponentially, and the focus, at first limited to a few diseases, has been rapidly extended to a larger spectrum of pathologies.

Here, we provide a concise overview of the potential of selenium-containing compounds, which represent a growing field of investigation for treating neurodegenerative diseases. Specifically, we focus on two neurological disorders that represent an open question for both scientists and clinicians: Alzheimer’s disease (AD) and Parkinson’s disease (PD).

For AD, there has been interest in dissecting the molecular mechanisms involved in its onset to allow the development of new therapeutic strategies [11]. The mechanisms responsible for the decline of cognitive abilities, cytotoxicity, inflammation and the oxidative stress induced by amyloid-β (Aβ) aggregates, all typical hallmarks of AD, have been extensively dissected to identify specific molecular targets for the design of highly selective small molecules. In this frame, some seleno-compounds, alone or in combination with other molecules, have demonstrated efficacy against stress oxidation and cytotoxicity, as well as against tau tangles and Aβ aggregate accumulation (Figure 1) [12].

In the case of PD, selenium derivatives have been tested both in vitro and in vivo for their ability to reduce neurotoxicity, cellular oxidation in the brain and the typical symptoms of the disease. Hence, selenium derivatives could represent a good strategy for new therapies [13].

Within this keynote review, we critically discuss recent findings in the field of selenium-based applications in neurological disorders, hand in hand with their relative targets.
