A strong blow to the head causes chemical changes within nerve cells that damage their structural proteins. Among the debris is a protein fragment called SNTF—which in more severe cases, spills into the bloodstream.</p>
<p>The new study followed 20 professional hockey players who got concussions with symptoms that lasted six days or more. And blood levels of SNTF were much higher one hour to six days later than were levels of the protein fragment in eight other athletes who had gotten concussions that cleared up within five days. Levels were also low in 45 non-concussed players tested during the preseason.</p>
<p>A blood test for SNTF might thus forecast recovery time from a head injury. Combined with other neurological tests, levels of this molecule could help doctors tell athletes when it’s safe to suit up again.</p> This week, we heard some sad…tag:kkartlab.in,2014-11-28:2816864:Comment:1222352014-11-28T02:25:03.900ZDr. Krishna Kumari Challahttps://kkartlab.in/profile/DrKrishnaKumariChalla

<p>This week, we heard some sad news,the death of Australian cricketer, Phil Hughes, due to head injury.</p>
<p>Phillip Hughes was the victim of a freakish accident, the kind that is rarely seen in any sphere of life and has only once before been recorded as the result of being struck by a cricket ball.<br/> When Hughes was hit in the neck by a ball during the Sheffield Shield match between New South Wales and South Australia at the SCG on 23rd, Nov. 2014, one of the main arteries to his brain was compressed, and such trauma can often be immediately fatal. Hughes initially stood for a second or two before collapsing forwards onto the ground, as players rushed to his assistance and called for medical help.<br/> Phillip took the blow at the side of the neck and as a result of that blow his vertebral artery, one of the main arteries leading to the brain, was compressed by the ball. That caused the artery to split and for bleeding to go up into the brain. He had a massive bleed into his brain. This is frequently fatal at the time.<br/> However, Phillip was resuscitated and then managed by doctors on the ground and paramedical staff. They all did an excellent job of keeping Phillip alive and he was able to be transported by ambulance to hospital in reasonable condition.<br/> Hughes was transported to the nearby St Vincent's Hospital in Sydney and was quickly admitted for surgery. It was necessary to immediately relieve the pressure on Hughes' brain from the compressed artery.<br/> The head injury that he suffered was catastrophic. He arrived well intubated and [had been] resuscitated very well. The first priority in that situation is to get an urgent CAT scan of the head to determine what the doctors can do. This CAT scan occurred very early and it was recognised early that doctors had to make an intervention into the brain to actually help get the pressure down in the brain.<br/> What sometimes happens in the brain is, if you put blood around the brain, a small amount, you will start to become a bit drowsy. If you put a lot of blood around the brain, you will become unconscious. Once the doctors had made the diagnosis of blood around the brain, and it's a subarachnoid blood, which is under pressure from the artery, the immediate transfer to theatre was necessary. He went to theatre and had extensive surgery to remove some of the skull around his brain to help allow the brain to expand so it wasn't compressed.<br/> The surgery took approximately 80 minutes and Hughes was then transferred back to the intensive carer unit and placed in an induced coma, in order to allow the brain to rest. However, Hughes showed little improvement over the next 48 hours and died on 25th after noon.<br/> Had he been taken faster to the hospital would it have helped Hughes survive? Such matters were more important when a patient was not receiving treatment. He was receiving treatment at the site of this incident incident by specialists. Ambulance waiting time is really more relevant when the injured or sick person is not being treated immediately. So there was nothing anymore anybody could do in this instance. The cricketer arrived at the hospital in a relatively good condition.</p>
<p>He was wearing a standard helmet used on cricket grounds. But that didn't cover the neck region and unfortunately he took the hit from the ball in that region. This was a freakish accident, because it was an injury to the neck that caused haemorrhage in the brain. This condition is incredibly rare. It's called vertebral artery dissection, leading to subarachnoid haemorrhage - that's the medical term for it. If you look in the literature there's only about 100 cases ever reported, so this is incredibly rare. Only one previous case ever reported as the result of a cricket ball. So it's important to realise that yes, we need to review all our procedures and equipment, but this is an incredibly rare type of injury.</p> Signs of concussion may inclu…tag:kkartlab.in,2014-08-07:2816864:Comment:1196692014-08-07T02:06:47.210ZDr. Krishna Kumari Challahttps://kkartlab.in/profile/DrKrishnaKumariChalla

<p>Signs of concussion may include:</p>
<p>• Headache or a feeling of pressure in the head<br/> • Temporary loss of consciousness<br/>
• Confusion or feeling as if in a fog<br/>
• Amnesia surrounding the traumatic event<br/>
• Ringing in the ears<br/>
• Slurred speech<br/>
• Delayed response to questions<br/>
• Appearing dazed<br/>
The main treatment for a concussion is rest. The idea is to give the brain time to heal itself. During that interval, a person should do everything possible not to impede recovery. In addition to avoiding physical activity, he should be told that under no circumstances should he drink alcohol or use any drugs; his brain is extremely vulnerable to the effects of such chemicals.</p> http://www.scientificamerican…tag:kkartlab.in,2014-07-24:2816864:Comment:1193192014-07-24T02:18:06.773ZDr. Krishna Kumari Challahttps://kkartlab.in/profile/DrKrishnaKumariChalla

<p class="t_article-subtitle">A new study in rats could one day benefit people suffering neurological conditions associated with the buildup of unwanted proteins in the brain, including traumatic brain injury and Alzheimer’s</p>
<p class="t_article-subtitle">March, 24th, 2016</p>
<p class="t_article-subtitle"><span>In a study on rats published this week in </span><em>The </em><em>Journal of Neuroscience</em><span> a team of researchers at University Hospital Zurich (UHZ) found that enhancing the slow-wave cycle of sleep after a traumatic head injury preserves brain function and minimizes damage to axons, the long projections from neurons that send signals to other cells in the brain.</span></p>
<p class="t_article-subtitle"><span><span>In the new study the researchers examined two different methods of inducing a slow-wave sleep state—the deepest sleep stage characterized by low-frequency, high-amplitude waves. During this stage, the brain clears out protein buildup, leading the researchers to question whether it could help treat rats that had suffered a brain injury.</span></span></p>
