A neuroimaging study is the first to show that white matter damage caused by severe obstructive sleep apnea can be reversed by continuous positive airway pressure therapy. The results underscore the importance of the “Stop the Snore” campaign of the National Healthy Sleep Awareness Project, a collaboration between the Centers for Disease Control and Prevention, American Academy of Sleep Medicine, Sleep Research Society and other partners.
Results show that participants with severe, untreated sleep apnea had a significant reduction in white matter fiber integrity in multiple brain areas. This brain damage was accompanied by impairments to cognition, mood and daytime alertness. Although three months of CPAP therapy produced only limited improvements to damaged brain structures, 12 months of CPAP therapy led to an almost complete reversal of white matter abnormalities. Treatment also produced significant improvements in nearly all cognitive tests, mood, alertness and quality of life.
“Structural neural injury of the brain of obstructive sleep apnea patients is reversible with effective treatment,” said principal investigator and lead author Vincenza Castronovo, PhD, clinical psychologist at the Sleep Disorders Center at San Raffaele Hospital and Vita-Salute San Raffaele University in Milano, Italy. “Treatment with CPAP, if patients are adherent to therapy, is effective for normalizing the brain structure.”
The study results are published in the September issue of the journal Sleep.
“Obstructive sleep apnea is a destructive disease that can ruin your health and increase your risk of death,” said American Academy of Sleep Medicine President Dr. Timothy Morgenthaler, a national spokesperson for the Healthy Sleep Project. “Treatment of sleep apnea can be life-changing and potentially life-saving.”
The “Stop the Snore” campaign was launched recently to encourage people to talk to a doctor about the warning signs for sleep apnea, which afflicts at least 25 million adults in the U.S. Sleep apnea warning signs include snoring and choking, gasping or silent breathing pauses during sleep.

The study involved 17 men with severe, untreated obstructive sleep apnea who had an average age of 43 years. They were evaluated at baseline and after both three months and 12 months of treatment with CPAP therapy. At each time point they underwent a neuropsychological evaluation and a diffusion tensor imaging examination. DTI is a form of magnetic resonance imaging that measures the flow of water through brain tissue. Participants were compared with 15 age-matched, healthy controls who were evaluated only at baseline.
A previous study by Castronovo’s research team found similar damage to gray matter volume in multiple brain regions of people with severe sleep apnea. Improvements in gray matter volume appeared after three months of CPAP therapy. According to the authors, the two studies suggest that the white matter of the brain takes longer to respond to treatment than the gray matter.
“We are seeing a consistent message that the brain can improve with treatment,” said co-principal investigator Mark Aloia, PhD, Associate Professor of Medicine at National Jewish Health in Denver, Colorado, and Senior Director of Global Clinical Research for Philips Respironics, Inc. “We know that PAP therapy keeps people breathing at night; but demonstrating effects on secondary outcomes is critical, and brain function and structure are strong secondary outcomes.”
GUANGZHOU, CHINA - JULY 15: (CHINA OUT) Han Bingbing, an 11-year-old girl from Heilongjiang, lies on a hospital bed after a surgery that removed her 15kg intraperitoneal tumor at 4PM on July 15, 2014 in Guangzhou, China. Han Bingbing, an 11-year-old girl from Heilongjiang, successfully received an 8-hour surgery operation to remove an intraperitoneal tumor. After 4 years, the tumor had reached a weight of 15kg and a size bigger than two footballs. As of June 18th, the tumor filled 5/6 of Bingbing’s abdomen and caused her internal organs to gradually collapse.
Another way to present the 9 types of intelligence as exemplified by my How Do We Measure Intelligence post.
The basic idea is that different people are good at different things. These 9 probably don’t cover the wide range of smarts we all possess, but it’s a start.
As Albert Einstein said, ”Everybody is a genius. But if you judge a fish by its ability to climb a tree, it will live its whole life believing that it is stupid.”
A 15-year-old boy is to undergo surgery on his exceptionally long neck, which causes him agonising pain. Fu Wengui, who lives in Beijing, China, suffers from a number of conditions. While the standard number of verbetrae in the neck is 7, Fu has 10, his father Fu Genyou claims. At age six, Wengui was diagnosed with congenital scoliosis and abnormal chest frame.’
There is no cure for HIV/AIDS, although treatments are much more successful than they used to be. A combination of drugs, known as anti-retrovirals (ARVs), help combat the virus and enable people to live longer, healthier lives without their immune system rapidly declining. Doctors Without Borders/Médecins Sans Frontières (MSF) HIV/AIDS programs offer HIV testing with pre- and post-test counseling, treatment and prevention of opportunistic infections, prevention of mother-to-child transmission, and provision of ARVs for people in the late stages of the disease. Our programs also generally include support of prevention, education, and awareness activities to help people understand how to prevent the spread of the virus.

"PALESTINIAN GIRL, YOUNGEST DOCTOR IN THE WORLD"
"When someone enrols in the medicine school that one of the longest schooling required profession, by the time they finish school they will be around 30-or at least on their late 20s. But not for this girl; Eqbal Asa’d is a Palestinian Muslim woman that started the Medicine school when she was just 14 years old, ‘myhijab.info’ reports. Asa’d got her Bachelor degree in Medicine with Honors and was set by the Guinness World Records as the youngest doctor in the World, according to the report. She has been signed to go to Ohio, U.S to continue her education even further and become a Pediatrician." - Source
YOU GUYS SHE IS THE YOUNGEST DOCTOR IN THE WORLD. SHE IS A FEMALE, A MUSLIM AND A MINORITY. AND SHE IS THE YOUNGEST DOCTOR IN THE WORLD.
WHY ARE WE NOT HEARING MORE ABOUT HER?
Silencio, tumultos alrededor, la espera ha cesado, el largo camino por conocer la naturaleza del hombre y del cuerpo que posee en este laberinto de misterios llamado vida, ha comenzado su curso… Dejar hacer lo que sabéis hacer y lo conseguireís.
Conseguimos un objetivo, luchamos por…
Un soberbio aplauso.
