This is your brain during a concussion 😬 🧠 😱

injuries No Comments »

It may look like Jell-O, but this brain is the same consistency as a real brain!

As Dr. Christopher Giza from UCLA demonstrates, the brain is made of soft tissue and floats in fluid inside of the skull. When the skull moves quickly, the brain can jostle around a lot, which can lead to neurological symptoms.

“Most concussions are recoverable,” Giza said.

But concussions can be difficult to identify and some people suffer more serious symptoms, particularly after multiple concussions.

Lab studies have shown a “window of vulnerability” after a first concussion, Giza said. Concussed athletes are three to six times more likely to get another concussion. If they rush back to play, their reflexes, reaction time and thinking may be slower, putting them at risk of a second concussion and longer recovery period.

The phony health craze that inspired hypnotism

In the 1780s, a charismatic healer caused a stir in Paris.

Scientific progress in the 18th century in Europe, a period known as the “Age of Enlightenment,” was demystifying the universe with breakthroughs in chemistry, physics, and philosophy. But medical practices were still relying on centuries-old treatments, like leeching and bloodletting, which were painful and often ineffective. So when Franz Anton Mesmer, a charismatic physician from Vienna, began “healing” people in Paris using an alternative therapeutic practice he called “animal magnetism,” it got a lot of attention.

Mesmer claimed that an invisible magnetic fluid was the life force that connected all things and that he had the power to regulate it to restore health in his patients. He was a celebrity figure until the King of France, Louis XVI, commissioned a group of leading scientists to investigate his methods in 1784.

Benjamin Franklin headed the commission, and they debunked the existence of the magnetic fluid in the first-known blind experiment. Mesmer was ruined, but “mesmerism” didn’t end there. The report also acknowledged that Mesmer’s methods were making his patients feel better, which they attributed to the power of the human imagination. This experiment ultimately laid the groundwork for our understanding of the placebo effect and inspired an evolution of Mesmer’s practice into something more recognizable today: hypnotism.

Thyroid Function Tests- what your results can mean

diseases No Comments »

If you’ve had thyroid function tests and received the results, this easy-to-understand short animation explains what they are measuring and what you are likely to see on the form.

These are blood tests used to check how your thyroid is working. They measure thyroid stimulating hormone or TSH, Thyroxine or T4 and Triiodothyronine or T3

The thyroid gland is found at the base of the neck. It produces thyroid hormones and releases them into the bloodstream. They control your body’s metabolism and regulate things like your heart rate and body temperature. It is important that your thyroid hormones levels are not too high or low and that they are kept in an even balance. If your T4 levels are low you may feel tired or experience weight gain. This is called Hypothyroidism . If your T4 levels are too high everything runs at a faster rate. You may experience heat intolerance or weight loss. This is Hyperthyroidism. There is a feedback mechanism to make sure levels remain stable. The pituitary gland controls T4 levels. WhenT4 levels are too low it releases more TSH. WhenT4 levels are too high it releases less TSH. In the blood sample sent to the lab we measure TSH, Free Thyroxine (FT4) and Free Triiodothyronine (FT3).

Concussion: Its Diagnosis and Treatment

injuries No Comments »

(Inside Science) — When someone arrives at an emergency room in a coma, someone with a serious brain injury, there is a long and well-established set of processes in place that allow for doctors to rapidly evaluate, triage and manage their treatment. The procedures for evaluating people who have a milder form of traumatic brain injury, a concussion, have historically been a little less well-defined. But experts say things have gotten better in recent years.

“At this point, our emergency department colleagues are quite adept at the evaluation and management of the patient with a concussion and the proper triage and steering of those patients into the expert hands, and that is often a neurosurgeon or a neurologist. But we also have primary care physicians who have sought additional specialty training. And we now have a pretty large army in the United States of people who can properly evaluate a patient with a concussion,” said David Okonkwo, clinical director at the UPMC Brain Trauma Research Center.
“It is a heterogeneous disorder. No two concussions are alike. And we see people have issues with migraines. We see people who have issues with dizziness and vestibular problems. We see other patients who have issues with memory and cognition. And then we also see patients who have a mental health manifestation of their concussion, be it in the form of anxiety or mood disturbance. These are just a short list of an even longer list of the ways in which a concussion can manifest itself,” said Okonkwo.

Dealing with concussion is complicated by the fact that people with the injury can experience completely different symptoms. The proper identification of the exact form of concussion an individual suffers is key, the experts say, because it helps to guide treatment.

“If it’s a balance-related issue, then you work on balance therapy. If it’s a visual-related issue, you work on visual therapy,” said Mark Proctor, neurosurgeon-in-chief at Boston Children’s Hospital.
For the majority of folks, treatment for a concussion starts with rest. The question of how long to rest has also evolved in recent years.

“So there used to be this concept of brain rest being, well, you put a child in a dark room until every symptom is gone. And it was discovered through some work at our hospital that that’s not always the right — well, clearly that’s not the best way to treat them. There’s a real benefit to near-total rest for about two to three days. But you don’t have to wait till someone’s completely asymptomatic before you get them out, you get them back to school, etc., because there’s other determinates such as social isolation and depression that start to factor in if you keep them out for too long,” said Proctor.

Proctor and his colleagues treat 400 to 500 mostly sports-related injuries every month at the brain injury center he directs. His experience there and the experience of doctors at other hospitals suggest a mostly good prognosis.

“For most people who sustain a concussion, there can be an expectation of the spontaneous resolution of symptoms and the spontaneous resolution of the problem over the course of days to a few weeks,” said Okonkwo.

“Eighty, 90 percent will be better in 10 to 14 days. And really no treatment is necessary other than the rest. What really is the vexing problem is that sort of 10 to 15 percent where those symptoms go on for a prolonged period of time,” said Proctor.

However, it’s very hard to predict who is going to be fine in two weeks and who isn’t. One of the challenges is that there is no specific biological test for concussion.

“We see this in so many other fields of medicine, where if you have a blood test that would clearly show that you had a concussion, that would be an enormous asset,” said Okonkwo.

Nor are there imaging biomarkers — ways of spotting a concussion on an MRI or CT scan. But many tools are now moving through development.

“We can have a reasonable expectation in the next two to three years of things crossing that FDA clearance hurdle and being put to use in routine clinical practice,” said Okonkwo.

For now, coaches and trainers have different forms of assessment tools. Cognitive tests can indicate if there’s a problem to determine if a player needs to be taken off the field, and taken to a doctor for further evaluation. Another advance that doctors hope for are better ways to treat specific types of brain injuries and concussions. There are still no existing FDA-approved drugs for the management of brain injury.
