Are We Brainwashed During Sleep?

In a new study, researchers suggest that tonight while you sleep, something amazing will happen within your brain.

Your neurons will go quiet. A few seconds later , blood flow out of your head . Then, a watery liquid called cerebrospinal fluid (CSF) will flow in, washing through your brain in rhythmic, pulsing waves.

The study is the first to illustrate that the brain's CSF pulses during sleep,and that these motions are closely tied with brain wave activity and blood flow.

The research was conducted by a team from Boston University.

Earlier studies have suggested that CSF flow and slow-wave activity both help flush toxic,memory impairing proteins from the brain. As people age, their brains often generate fewer slow waves.

In turn, this could affect the blood flow in the brain and reduce the pulsing of CSF during sleep., leading to buildup of toxic proteins and a decline in memory abilities.

Although researchers have tended to evaluate these processes separately, it now appears that they are very closely linked.

The coupling of brain waves with the flow of blood and CSF could provide insights about normal age related impairments as well.

As their research continues to move forward, the team has another puzzle they want to solve: How exactly are our brain waves, blood flow , and CSF coordinating so perfectly with one another?

One explanation may be that when the neurons shut off, they don't require as much oxygen, so blood leaves the area.

As the blood leaves , pressure in the brain drops, and CSF quickly flows in to maintain pressure at safe level.

DID PLACEBO EFFECT WORKS?

what is placebo effect? It is a phenomenon in which some people experience a benefit after the administration of inactive substance. A placebo is a fake treatment that in some cases it can produce a realistic result. This depends upon the expectation of the patient,the more a paerson expects the treatment will work, it is more likely to respond. Things that will influence the placebo effect includes The nature of illness The belief system of the patient during treatment The expectation of the patient if fulfilling The positive message from the doctor about treatment EFFECT ON HORMONES Taking the placebo tretament triggered the release of endorphins. Endorphins have a similar structure as morphine and other opiate painkillers and act as the brains own natural painkillers. Other possible things include conditioning , motivation and expectation. People who are highly motivated

CAN YOU DIE FROM RHEUMATOID ARTHRITIS(RA)?

WHAT IS RHEUMATOID ARTHRITIS(RA)? Rheumatoid Arthritis(RA) is an autoimmune disease that can cause joint pain and damage throughout your body. It is a chronic disease marked by symptoms of inflammation and pain in the joints. It can also cause inflammation of organs such as the lungs, eyes, skin, and heart. There is no cure for RA, but medications can stop the progression of the disease and ease symptoms. The joint damage that RA causes usually happens on both sides of the body. Treatment is possible when RA is diagnosed early. SIGNS AND SYMPTOMS The sign and symptoms of RA come and go, depending upon the degree of inflammation. When the body tissues are inflammed, the disease is active and when the tissue inflammation subsides the disease is inactive. THE SIGN AND SYMPTOMS INCLUDE; Fatigue low grade fever muscle and joint pain joint tenderness joint deformity loss of energy rheumatoid nodules loss of joint function limping stiffness Muscle and joint stiffness are usually seen in the

Is Dexamethasone beneficial for COVID-19 patients ?

Dexamethasone : Dexamethasone is a steroid that has been used since the 1960s to reduce inflammation in a range of conditions , including inflammatory disorders and certain cancers. The World Health Organisation (WHO) welcomes that the initial clinical trial esults from the United kingdom (UK) that shoe dexamethasone , a corticosteroid , can be lifesaving for patients who are critically ill with COVID-19. For patients on ventilators , the treatment was shown to reduce mortality by about one third , and for patients requiring only oxygen , mortality was cut by about one fifth , according to preliminary findings shared with WHO. The benefits was only seen in patients seriously ill with COVID-19 , and was not observed in patients with milder disease. WHAT DEXAMETHASONE IS USED FOR : As an anti-inflammatory medication , It relieves inflammation in various parts of the body, It is used specifically to decrease swelling (edema) , associated with tumors of the spine and brain, and to treat e
