Exercise and dementia - Health Report - ABC Radio National Norman Swan: Good news for delaying the onset of Alzheimer's disease and dementia, even in people who seem to be at increased risk because of the build-up of dementia related substances in the brain called amyloid and tau. There's a drug you can take, it's called exercise. Jasmeer Chhatwal is a neurologist at Harvard Medical School in Boston and I spoke to him earlier. Internet Addiction Disorder 1.What is Internet Addiction Disorder? Internet addiction is defined as any online-related, compulsive behavior which interferes with normal living and causes severe stress on family, friends, loved ones, and one’s work environment. Internet addiction has been called Internet dependency and Internet compulsivity.
Survey underlines journalists’ increasing dependency on social media Social media is seen as an “important tool” by the majority of UK journalists, according to a recent survey. But members of the press questioned say that the PR industry by and large has yet to fully grasp how to interact with journalists on social platforms. New Media Knowledge went in search of answers.

Scientists believe that shining light directly into the brain areas damaged in Alzheimer’s through the nose and skull can reverse the disease. The new device, called the Neuro RX Gamma headset, being tested was developed by Vielight, a leader in brain photobiomodulation (PBM) technology. The headset equipped with LEDs is based on Vielight’s proprietary PBM technology. The Neuro RX Gamma is non-invasive, delivers near-infrared energy, pulsing at the gamma rate of 40Hz, to the region responsible for memory in the brain in daily treatment sessions.
Is Internet Addiction a Real Thing? Marc Potenza, a psychiatrist at Yale and the director of the school’s Program for Research on Impulsivity and Impulse Control Disorders, has been treating addiction for more than two decades. Early in his career, he, like most others studying addiction at the time, focussed on substance-abuse problems—cocaine and heroin addicts, alcoholics, and the like. Soon, however, he noticed patients with other problems that were more difficult to classify. Dependency Theory media depends on the social context (or: Media System Dependency Theory) History and Orientation Dependency theory was originally proposed by Sandra Ball-Rokeach and Melvin DeFleur (1976). This theory merged out of the communication discipline. Dependency theory integrates several perspectives: first, it combines perspectives from psychology with ingredients from social categories theory.
Concussion Type of traumatic brain injury Concussion, also known as mild traumatic brain injury (mTBI), is typically defined as a head injury that temporarily affects brain functioning. Symptoms may include loss of consciousness (LOC); memory loss; headaches; difficulty with thinking, concentration or balance; nausea; blurred vision; sleep disturbances; and mood changes. Any of these symptoms may begin immediately, or appear days after the injury. It is not unusual for symptoms to last 2 weeks in adults and 4 weeks in children. Fewer than 10% of sports-related concussions among children are associated with loss of consciousness. Video explanation of concussions in children Internet Addiction Forum Our partner News Site map Second-impact syndrome Second-impact syndrome (SIS) occurs when the brain swells rapidly, and catastrophically, after a person suffers a second concussion before symptoms from an earlier one have subsided. This second blow may occur minutes, days or weeks after an initial concussion, and even the mildest grade of concussion can lead to SIS. The condition is often fatal, and almost everyone who is not killed is severely disabled. The cause of SIS is uncertain, but it is thought that the brain's arterioles lose their ability to regulate their diameter, and therefore lose control over cerebral blood flow, causing massive cerebral edema.
Everyone Knows Memory Fails as You Age. But Everyone Is Wrong. So how do we account for our subjective experience that older adults seem to fumble with words and names? First, there is a generalized cognitive slowing with age — but given a little more time, older adults perform just fine. Second, older adults have to search through more memories than do younger adults to find the fact or piece of information they’re looking for. Your brain becomes crowded with memories and information.
Allen Newell Allen Newell (March 19, 1927 – July 19, 1992) was a researcher in computer science and cognitive psychology at the RAND Corporation and at Carnegie Mellon University’s School of Computer Science, Tepper School of Business, and Department of Psychology. He contributed to the Information Processing Language (1956) and two of the earliest AI programs, the Logic Theory Machine (1956) and the General Problem Solver (1957) (with Herbert A. Simon). He was awarded the ACM's A.M. Mike Webster American football player Webster was the first former NFL player diagnosed with chronic traumatic encephalopathy (CTE). Since his death, he has become a symbol for head injuries in the NFL and the ongoing debate over player safety. His doctors were of the opinion that multiple concussions during his career damaged his frontal lobe, which caused cognitive dysfunction. Webster died in 2002 at the age of 50 of a heart attack.  Mike Webster was regarded as the best center in the Big Ten during most of his career at the University of Wisconsin. At 6-foot-1, 255 pounds, he was drafted in the fifth round of the 1974 NFL Draft by the Pittsburgh Steelers.
Bennet Omalu Nigerian-American pathologist Bennet Ifeakandu Omalu (born September 30, 1968) is a Nigerian-American physician, forensic pathologist, and neuropathologist who was the first to discover and publish findings of chronic traumatic encephalopathy (CTE) in American football players while working at the Allegheny County coroner's office in Pittsburgh. He later became the chief medical examiner for San Joaquin County, California, and is a professor at the University of California, Davis, department of medical pathology and laboratory medicine. Early life Omalu was born in Nnokwa, Idemili South, Anambra in southeastern Nigeria on September 30, 1968, the sixth of seven siblings. He was born during the Nigerian Civil War, which caused his family to flee from their home in the predominantly Igbo village of Enugu-Ukwu in southeastern Nigeria. Education and career
Chronic traumatic encephalopathy Neurodegenerative disease caused by repeated head injuries Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease caused by repeated head injuries. Symptoms may include behavioral problems, mood problems, and problems with thinking. Symptoms typically do not begin until years after the injuries. CTE often gets worse over time and can result in dementia. It is unclear if the risk of suicide is altered. Most documented cases have occurred in athletes involved in contact sports such as boxing, American football, professional wrestling, ice hockey, rugby, and soccer. Other risk factors include being in the military, prior domestic violence, and repeated banging of the head. The exact amount of trauma required for the condition to occur is unknown. Definitive diagnosis can only occur at autopsy. Chronic traumatic encephalopathy is a form of tauopathy. Signs and symptoms
