 In case you are not familiar with free radicals, they are damaged oxygen molecules, which are missing an electron and because they must "steal" their missing electron from another molecule, they can set off a chain reaction of destruction as one molecule after another loses and steals back the electrons it needs to be stable.


 An antioxidant is a molecule that can donate an electron to a free radical and stop the chain reaction. By stopping that chain reaction, antioxidants prevent the cell from being damaged and sometimes even destroyed by the action of free radicals.


As I already mentioned, the action of antioxidants is vitally important to every organ and organ system in your body, but for the purpose of this article, I am going to focus on antioxidants and your brain.


Your brain is highly vulnerable to free radical damage because although it only accounts for about 2% of your body mass, about 20% of the oxygen you take in is used in your brain. Free radicals - damaged oxygen molecules are caused by many different things, but one cause is a natural and inevitable by-product of metabolizing oxygen. Since 20% of your oxygen intake goes to your brain, it's easy to understand that the cells in your brain will be subjected to a high number of free radicals.


Lipid Peroxidation and Your Brain

Within your brain is a large concentration of naturally occurring molecules called Lipids. Lipids include fats, waxes, sterols and some fat soluble vitamins like A, D, E and K. Lipids store energy, they are signaling molecules and are structural components of your cell membranes. Lipid peroxidation is the name given to free radical damage to Lipids.


Your defense against Lipid peroxidation in the brain are antioxidants and in particular a group referred to as Network Antioxidants or the Antioxidant Network, which is made up of Vitamins C, E, CoEnzymeQ10, Lipolic acid and Glutathione. Network Antioxidants work together to not only clean up free radicals in the brain, but they are uniquely capable of repairing each other. Of the Network Antioxidants, the most powerful is Glutathione- The master Antioxidant, which is naturally manufactured by your body and resident in each and every cell.


Sadly, your brain has naturally lower levels of the Master Antioxidant, Glutathione than do other organs and when it comes to an aging brain, the natural supply is further depleted because our ability to produce Glutathione falls by about 10% for each decade after our twenties. But your brain needs Glutathione to stay healthy. Look at the role that Antioxidants play in connection with Alzheimer's Disease - senile dementia.

The Doctor-Nurse Relationship

 The doctor nurse relationship is a constantly evolving connection. Although historically the dynamic between doctors and nurses has been a bit less than ideal, in the last twenty years there have been steady advancements for a better rapport. The main issue is, and continues to be, communication -- between doctor and nurse, between patient and doctor, between nurse and patient. The need for collaboration and teamwork is evident. Fifty years ago, there was a clear distinction between doctors and nurses. Most specifically, doctors were men and nurses were women. Doctors would see a patient once or twice a day, engaging them only to make assessments of their condition, while nurses would deal with all they physically intimate and demanding aspects of the care, like baths, toilet trips, and administering medicine. Today, though there is still a majority of female nurses, there is no gender divide in the healthcare industry and almost half of every medical school class is comprised o...

General Management of Acute Stroke

 Once a firm diagnosis is made, specific therapy and care begin. Some traditional treatments are known to have uncertain foundation. Active research is being directed to the causes of neuronal damage, the progression of acute stroke and alleviation of the insult  Stroke may be categorized as either ischaemic or haemorrhagic in nature. While ischaemic cerebrovascular disease predominates throughout the world, cerebral haemorrhage may account for 30 to 40% of stroke among Chinese and Japanese. As cerebral haemorrhage patients may be fully alert and clinically resemble those suffering from ischaemic vascular disease, treatment of stroke must be based on firm radiological identification of the underlying pathology. The cause of stroke has to be clearly identified so that specific risk factors are controlled, and treatment is tailored to individual requirements. Good management of stroke patient should begin with sound basic diagnosis, investigation and nursing care. Dedicated stri...
