Microcephaly brain size linked to mutation in stem cell micro environment – Medical Xpress

Posted: Published on August 9th, 2017

Credit: Stuart Hay, ANU New research highlights the significant role the surrounding environment of stem cells, known as the niche, might play in the brain size of babies with microcephaly. Mutations in certain genes have been linked with small brains (microcephaly), dwarfism and other developmental defects. Since the discovery of these microcephaly genes, extensive research has been conducted to determine how they cause smaller brains in patients. Although much research has focused on defective neural stem cell function as the likely culprit in causing small brains in patients with a mutation in the microcephaly protein WDR62, researchers at the Australian National University (ANU) have found that reduced brain size is caused by loss of WDR62 function in the stem cell microenvironment. "Using genetic models we found when this gene was mutated in the neural stem cells the brain size wasn't affected at all. The neural stem cells were reduced but the other cells in the brain compensate," said Dr Quinn group leader at The John Curtin School of Medical Research at ANU. "Instead, only reduction of WDR62 in the stem cell microenvironment (or niche) severely reduces brain growth by … Continue reading

For health-care VC, the search for a Parkinson’s cure turns personal – CNBC

Posted: Published on August 9th, 2017

His nonprofit foundation has three main goals: first, find a way to halt progression of Parkinson's with GBA. Next, identify a regenerative approach to repair the damage it wreaks. And finally, find a way to prevent it altogether. Accomplishing even just the first would be to do something that's never been done. Despite years of effort and capital from the Michael J. Fox Foundation for Parkinson's Research to funding from Google founder Sergey Brin treatments for Parkinson's disease have remained as elusive as those for other devastating neurodegenerative conditions, like Alzheimer's. "It has been extremely challenging, and many clinical trials have failed," said Dr. Dimitri Krainc, chairman of the department of neurology and director of the Center for Rare Neurological Diseases at Northwestern University Feinberg School of Medicine. "However, we have learned important lessons from these failures." The disease was first described two centuries ago, in 1817, by British surgeon James Parkinson. In a document he called "An Essay on the Shaking Palsy," Parkinson described a condition characterized by "involuntary tremulous motion, with lessened muscular power." We know now that Parkinson's results from loss of brain cells, including those that produce the chemical messenger dopamine, important for coordinating movement. Treatments … Continue reading

How Medical Cannabis Could Treat Parkinson’s Disease … – CannaTech.news

Posted: Published on August 9th, 2017

Over the past two decades, medical cannabis has become an alternative treatment option for many medical patients across the globe. While medical studies in this area are by no means complete, there have been many promising findings both in the medical lab and outside of it, which may be indicators of future treatments that could be based on medical cannabis. A disease called Parkinsons disease has recently moved to the forefront of medical investigation involving medical cannabis treatments. Parkinsons disease is a neurodegenerative brain disorder that occurs when there is a slow reduction in the amount of dopamine produced in the human brains nerve cells. Dopamine is the brain chemical that allows coordinated and smooth muscle movements in the body. Because the disease affects a persons movements and begins gradually, and because there is no laboratory test for the disease, it can be difficult to spot early on. Through a thorough examination of a patients medical history and repeated neurological exams, most cases can be diagnosed. Parkinsons disease is not generally diagnosed in younger people; age 60 is the age when it usually begins to affect a patient. For the disease to affect a patient noticeably, 60-80 percent of a … Continue reading

Good Samaritan now offers new treatment for Parkinson’s – Terre Haute Tribune Star

Posted: Published on August 9th, 2017

Good Samaritan at Vincennes is now offering a new treatment for Parkinsons disease.Physical therapistJoy Uy andoccupational therapistJames Schenk of Good Samaritan are certified providers for this Parkinsons treatment program. LSVT is a new approach to treatment of Parkinsons disease involving the concept of neuroplasticity, the brains ability to reorganize itself by forming new neural connections throughout life. This approach aims to address the internal aspects of Parkinsons disease symptoms, leading to significant functional movements. There are two sections of LSVT, BIG and LOUD. LSVT BIG is a standardized treatment protocol, which is customized to the unique goals of each patient including both gross and fine motor skills. LSVT LOUD is customized to the unique communication goals of each person across a range of disease severity and communication impairments. Over the last 25 years, the National Institutes of Health have been researching and developing LSVT BIG and LOUD to help treat patients with symptoms associated with Parkinsons disease. Uy says she and Schenk are currently utilizing the LSVT treatment protocol to manage the symptoms of Parkinsons patients in Good Samaritans Rehabilitation Center.

A dose of longevity hormone may boost treatment for Parkinson’s – Economic Times

Posted: Published on August 9th, 2017

NEW YORK: A single dose of a life-extending protein hormone -- naturally produced in both kidney and brain -- may lead to rapid improvement in cognitive and physical performance, indicating potential for the development of treatments for Parkinson's and Alzheimer's disease, a study has shown. The findings showed that administering hormone klotho like a drug improved cognition, including spatial learning and working memory, as well as the ability to navigate and to learn new tasks -- deficiencies which may lead to age-related neurodegenerative conditions such as Parkinson's and Alzheimer's disease -- in young, ageing or impaired mice with normal or low levels of the hormone. However, it remains unexplained how the piece of the klotho hormone that was injected into the bodies of the mice caused these effects since there is no evidence that klotho is able to enter the brain from the bloodstream, the researchers said. "It makes us wonder about the connection between the body and the brain," said Dena Dubal, Associate Professor at the University of California - San Francisco. "What we saw with acute klotho administration may be similar to what happens with exercise, which also improves cognition and brain health, although we don't know how," … Continue reading

Injured soldier Ben Parkinson launches review of his care – BBC News

Posted: Published on August 9th, 2017

Image caption Ever since Ben Parkinson was a young boy he had wanted to be a paratrooper and he realised his dream when he joined the 7th Parachute Regiment Royal Horse Artillery A paratrooper who survived some of the the worst-ever battlefield injuries has asked lawyers to investigate concerns over his care. Lance Bombardier Ben Parkinson lost both legs and suffered more than 40 injuries in a landmine blast in Afghanistan in 2006. The 31-year-old from Doncaster and his mother are now calling on his care providers for more help. NHS England said it was working to arrange reviews of his care. Lawyers claim his care providers are in breach of the Armed Forces Covenant. More stories from around Yorkshire The covenant is a promise that those who serve, or have served, in the armed forces, and their families, are treated fairly. L/Bombardier Parkinson was two weeks from finishing a tour of Afghanistan when his Land Rover hit a mine. Medical staff did not expect him to survive the explosion. The former paratrooper's care is provided by the Ministry of Defence (MoD), NHS England and Doncaster Clinical Commissioning Group (CCG) but his mother, Diane Dernie, said the organisations failed to … Continue reading

Kimberly Mascott Zieselman, Opinion contributor , TEGNA 9:10 AM. PDT August 09, 2017 Kimberly Mascott Zieselman, months after her intersex surgery, in Concord, Mass., in 1983. (Photo: Family Photo) I was born with typically male XY chromosomes and internal testes instead of ovaries and a uterus, but my body developed to appear typically female. My intersex condition was invisible until I reached puberty and failed to menstruate like other girls. On the advice of doctors at a major hospital, my parents agreed that I should have surgery to remove my healthy gonads, without my knowledge or consent. A clinical trial saved my life. It could save yours, too. Transgender military ban: Trump isolates America once again My natural hormone production ceased, and I was forced onto hormone replacement therapy for the rest of my life. I was just 15. Doctors also recommended to my parents that I receive invasive surgery to create a more typically sized vagina thankfully, my parents refused. I didnt find out about any of this until I was 41 years old. Intersex people like me up to1.7% of the population are born with sex characteristics that do not fit typical definitions of male or female. I … Continue reading

Transgender candidate faces off against longtime conservative – W*USA 9

Posted: Published on August 9th, 2017

Evan Koslof, WUSA 9:46 AM. EDT August 09, 2017 MANASSAS, VA. (WUSA9) - Even in a hyper-political area like the DMV, there's often not a lot of interest around a local race for a Virginia delegate. But this year, all eyes are on the 13thDistrict, where a longtime incumbent, most well-known for his proposed bathroom bill, is facing off against a transgender woman. Democrat Danica Roem joined WUSA9 for an interview in Manassas to talk about why she decided to run. Meanwhile, Republican Robert Marshall didn't want to talk on camera, but did answer questions for WUSA9through email. Danica Roem: "I don't want to just be known as the transgender candidate," said Roem, as she joined WUSA9 for an interview. Roem is a longtime journalist in the area, and said many issues define her campaign, in particular road improvements along Route 28. Nonetheless she said that fighting LGBTdiscrimination is also very important to her. At one point in the interview, Roempulled out two medical containers, full of pills, and grabbed two small capsules. She explained that these are the pills she's been taking, during her transition. "I wouldn't be taking this if my doctor and I both thought that there … Continue reading

Perimenopause Problems: How Changing Hormones Exacerbate ADHD Symptoms – ADDitude

Posted: Published on August 9th, 2017

An ADDitude reader wrote: I am a 42-year-old business executive diagnosed with ADHD. I have a confession to make. Lately, I dont like calling people on the phone or returning calls. I think perimenopause may be causing this glitch. I also find myself getting confused and shutting down when confronted with a bunch of projects at work all at once. I need more time to process things. I know I have ADHD, and I know my hormone profile is changing. I take medication, but what strategies do you have to ease this collision course between diagnosis and hormones? What can I do to make things easier on myself? ADHD symptoms change as we age, and as life circumstances become more complicated and stressful. Hormones, in particular, often exacerbate ADHD symptoms as women edge closer to menopause. In fact, as youve pointed out in your question, this worsening of symptoms may occur during perimenopause, when estrogen levels begin to drop. We know that when estrogen levels decrease, cognition suffers. Women struggle with memory, word retrieval, and other cognitive activities. In fact, for some, the change in cognitive function is so drastic that some think they are developing dementia or Alzheimers. Lower … Continue reading

Parents and Doctors, Hold Off on This ‘Devastating’ Surgery – Newser

Posted: Published on August 9th, 2017

(Newser) When Kimberly Mascott Zieselman was 15, she had surgery she now says caused "irreversible harm" due to others' "discomfort with difference." In her op-ed for USA Today, Zieselman explains how, as a young teen, she didn't get her period like other girls, and when her parents took her to get examined, doctors made a surprising discovery: She was intersex, meaning a person born with both male and female characteristics. In Zieselman's case, that meant that even though on the outside she appeared female, she had male XY chromosomes and testes (instead of ovaries and a uterus) inside her body. She had androgen insensitivity syndrome, so that her body resisted male sex hormones called androgens and led to an external appearance of being female. She says her parents agreed, per physician advice, to have her "healthy gonads" taken out, "without my knowledge or consent." She was also placed on a lifelong hormone replacement therapy, as her natural hormones had halted. She says these types of "non-consensual and medically unnecessary procedures" on intersex kids have been common since the '60s, with "often catastrophic" results and "largely unproven" benefits. "We are erased before we can even tell our doctors who we are," … Continue reading
