A new study has first time revealed the complex interaction between cognition and the biological structure of the human brain. through scans, they have shown that the active training of the working memory triggers noticeable changes in the number of dopamine D1 receptors in the brain cortex. This study was conducted by the Karolinska Institutet.

Professor Torkel Klingberg, who led the study, says that, “Brain biochemistry doesn’t just underpin our mental activity; our mental activity and thinking process can also affect the biochemistry. This hasn’t been demonstrated in humans before, and opens up a floodgate of fascinating questions.”

It is stated that the neurotransmitter dopamine is a key element in certain functions of the brain. Thus, a disturbance in the dopamine system could adversely affect the process of the memory, which could in turn make recollection of data over a short period of time difficult. Impaired working memory is found to be, in turn, linked to various cognitive related complications like schizophrenia and ADHD.

The study investigators had earlier revealed that an enhancement of the working memory could be undertaken through a few weeks of intensive training. In unison with the Stockholm Brain Institute, these investigators attempted to better understand this issue. In the present study, through the use of Positron Emission Tomography they have assessed the brain.

The study authors say that the answer to poor working memory cannot be given by the changes noticed in the number of dopamine receptors in the brain. These changes could have taken place as a result of the absence of memory training, or even other environmental factors. they hope to soon discover new treatments that include both memory training and treatment drugs.

They state that their findings could benefit patients suffering from cognitive impairments linked to stroke, chronic fatigue syndrome, ageing, etc.

Their findings are published in the Science journal.

People have many misconceptions anorexia. Due to various popular myths surrounding the phenomenon of eating disorders or lack of understanding, most people with anorexia denatured assimilate ideas and people that interest you.

probably the most common treatment can not be wrong, terribly defines anorexia as an illness. Although both physical and psychological damage caused by anorexia, an eating disorder can be treated successfully, and its side effects of this typecan be overcome with time. In fact, half of a program of appropriate treatment, the vast majority of patients diagnosed with anorexia disorder can be achieved relatively short period of time completely.

Statistics at some point in their lives, more than 80 percent of people with anorexia were compared with counseling, support and encourage families of all vehicles were seized with the show.In addition, the majority of people suffering from anorexia in the past to win full control over their lives, it was possible to provide emotional balance. however, people affected by the fact that they inflict a lot of physical and emotional damage, such as anorexia, are required for this type of disorder has been discovered in time, and emergency response is necessary.

Common myths and learning in Anorexia

another popular myth that surrounds this type of eating disorder, suggest the idea that anorexics do not eat. ThisThe idea is quite exaggerated and changing! even though restrictive anorexic tuttuklar?ndan with lots of food and diets are human, after all, and therefore very difficult to eat! purpose and vegetarian diets are often followed by foods high in calories so I usually anorexic, thin with a body to reach their goals. at any time, just to dispose of anorexia, excessive amounts of food to eat at the same time, the over-the-purge behaviors can beright, then vomiting or with laxatives and diuretics. however, this behavior is more common among bulimics.

more commonly confused with anorexia and bulimia. Although similar to anorexia, bulimia, and more generally, between these two common types of eating disorders have a variety of different features to meet the challenges of each badge. however, people with eating disorders, the oscillation behavior of bulimics and anorexics can be easily, or vice versaversa.

First, a physical point of view, anorexics and bulimics main difference between the body weight. Although the weak anorexics, bulimics usually have average or the average body weight. therefore, unlike the case of anorexics, bulimic patients is even more difficult to identify a person.

Psychologically, anorexics and bulimics The main difference between people with anorexia will have a strong ambition to be more and bulimics. these two categories, while low self-esteem and a distorted self-image, bulimics are usually more likely to suffer from depression. Oscillating between binging and purging their food by making contradictory, complex behaviorsthem very vulnerable to develop feelings of guilt and confusion.

An Ontario man with multiple sclerosis died of complications after a controversial treatment in Costa Rica to open up his neck veins, CBC News has learned.

Mahir Mostic, 35, of St. Catharines died on Oct. 19, one day after doctors in the Central American country tried to dissolve a blood-clot complication.

“We didn’t find exactly what happened with Mahir, but I mean it was very terrible story for us,” vascular surgeon Dr. Marcial Fallas of Clinica Biblica in San Jose said Thursday.

“He was a person that was looking [for] some way to improve his life. He found that for a short period of time his life improved.”

After Mostic paid $30,000 US to go to Costa Rica for treatment in late June, he was operated on three times to have a mesh stent inserted to prop open a vein in his neck.

“He started feeling better and got his energy back,” his girlfriend, Bedrana Jelin, said from Visoko, Bosnia-Herzegovina.Mahir Mostic’s MS symptoms improved after his neck veins were opened, but then worsened with fatal blood clot complications, his doctor in Costa Rica said. (Bedrana Jelin)

But his MS symptoms started getting worse and a blood clot formed around the stent in the vein, Fallas said. An ultrasound showed that the vein was 80 per cent blocked.

Mostic was disappointed and desperate. His friends and loved ones raised another $8,000 US to send him back to Costa Rica after they had trouble getting a specialist to see him in Canada.

“They didn’t want to touch him because he was done outside of Canada,” Jelin said.

Mostic flew back to Costa Rica for treatment, but died in hospital there after doctors tried to dissolve the clot using powerful medication that Fallas thinks triggered internal bleeding.

Fallas said his clinic normally doesn’t use stents because they are considered risky. but he said Mostic was willing to take the risk.

Unable to walk

Mostic had been diagnosed with a fast-moving type of multiple sclerosis three years ago. When he first sought the vein-opening procedure, he hadn’t walked for 18 months.

Angioplasty, inflating small balloons to open up arteries, is commonly done for heart patients but is not an approved procedure for unblocking neck veins in MS patients in Canada.

A blood clot in the vein might be more dangerous to fix than to leave alone, said Dr. Barry Rubin, the head of vascular surgery at Toronto’s University Health Network.

“Since veins have a remarkable ability to grow in other locations if one of the veins is blocked, generally it’s extremely safe to just put the patient on blood thinners to try and prevent the clot from extending or breaking off into the lungs, and just waiting,” said Rubin, who is also a professor of surgery at the University of Toronto.

“You don’t have to go in and dissolve the clot once it’s formed, if it’s in a vein.”

Rubin said Mostic isn’t the first case of a serious complication in an MS patient who has sought treatment outside Canada. Last week, he treated a woman who had the vein procedure in Mexico.

“We found extensive clotting in the left arm reaching into the chest veins, and some of the clots had broken off and travelled to her lungs, which is called a pulmonary embolus, which is life threatening, potentially life-threatening complication.”

Dr. Paulo Zamboni of Italy is a leading proponent of treating multiple sclerosis with angioplasty. His therapy is based on an unproven theory, known as chronic cerebrospinal venous insufficiency (CCSVI), that blocked veins in the neck or spine contribute to MS.

In April, Zamboni warned patients attending the American Academy of Neurology’s annual meeting in Toronto against using stents — small mesh coils — because of the high risk of the stents moving and lack of knowledge about their long-term effects.

In Canada and the U.S., seven research studies are underway to test for vein narrowing in people with MS compared with people without MS.

“Something has to be done because other people are suffering,” Jelin said. “And something has to be done because it’s not fair I lost someone very close to me.”
