Q: CLOSE 2-year-old Eden Carlson's road to recovery has defied the odds and is possibly the first medical case of its kind. USA TODAY

 A 2-year-old from Arkansas who nearly drowned in her family's swimming pool is on the mend thanks to a type of oxygen therapy. 
  
 In February 2016, Eden Carlson broke through her baby gate and headed into the family pool. Her mother, who believed the child was safe playing with older siblings, was in the shower, WDSU News reports. Eden was found after struggling in cold water for at least 10 minutes, without a heartbeat, the station reports. She was not expected to survive, but she did. 
  
 Eden was left with severe brain damage. She couldn't speak or walk. Her parents were told she would never talk, walk, eat on her own or react to her surroundings. They couldn't accept that, and looked at other options. 
  
 Fifty-five days after Eden's near drowning, Paul Harch of Hyperbaric Medicine at LSU Health New Orleans School of Medicine started hyperbaric oxygen therapy. Oxygen administered at sea-level pressure filled Eden's nose for 45 minutes, twice a day. Eden started hyperbaric oxygen therapy about a month later, breathing pure oxygen in a pressurized chamber, five days a week. The treatment isn't new, but it is experimental and not approved by the FDA. 
  
 In May, the miraculous happened: Eden laughed. She moved her arms, hands and eyes. She could speak. Today, she's able to climb up stairs on a play set by herself. The new responses happened gradually, but to much surprise. 
  
 Her brain damage started to reverse — what could be a first in medical history. 
  
 “The startling regrowth of tissue in this case occurred because we were able to intervene early in a growing child, before long-term tissue degeneration,” Harch said in a statement. 
  
 Eden's mom, Kristal Carlson, says the treatments saved her daughter, and could help others suffering from brain injuries. 
  
 "She’s getting so much better all the time," Carlson told USA TODAY. "In a couple of years, it’s going to be like she never had an accident." 
  
 Harch and Edward Fogarty, at the University of North Dakota School of Medicine, documented her progress in a report published in Medical Gas Research.

Using oxygen therapy, scientists were able to restore her ability to walk and talk just months after the accident, in which she spent 15 minutes submerged in a swimming pool and two hours where her heart did not beat on its own. 
  
 The accident took place in February 2016. Two-year-old Eden Carlson had managed to get through a baby gate and fall into the family swimming pool and was in the 5 degree Celsius water for up to 15 minutes before being discovered.

 After being resuscitated and treated in hospital for just over a month, she was unresponsive to all stimuli. She was immobile and constantly squirmed and shook her head. MRI scans showed deep injury to the brain’s gray matter, as well as loss of white and gray matter. 
  
 In a bid to reverse the brain damage, researchers at the LSU Health New Orleans School of Medicine and the University of North Dakota School of Medicine began treating her with two types of oxygen therapy. 
  
 This includes normobaric oxygen therapy, where levels of oxygen given are the same as at sea level, and hyperbaric oxygen therapy (HBOT), where they are given pure oxygen at pressures higher than that of the atmosphere within a special chamber. 
  
 Fifty five days after the drowning accident, doctors started giving Eden normobaric oxygen for 45 minutes twice per day. This appeared to make her more alert and awake, and she stopped squirming. She started laughing more and was able to move her arms and hands, and grasp with her left. Scientists also noted eye-tracking movements and some speech.

 After 78 days, Eden began HBOT therapy, with 45 minute sessions five days per week for four weeks. After 10 sessions, her mother said she was almost back to normal other than motor function. After 39 sessions—coupled with physical therapy—Eden was able to walk and her speech had returned to normal. Her cognitive abilities had improved and motor function was almost restored to pre-drowning levels. 
  
 An MRI scan a month after the 40th HBOT session showed almost complete reversal of the brain damage initially recorded. Researchers believe the oxygen therapy, coupled with Eden having the developing brain of a child, had activated genes that promote cell survival and reduce inflammation—allowing the brain to recover. The case report is published in the journal Medical Gas Research. 
  
 Paul Harch, who treated Eden, said in a statement: “The startling regrowth of tissue in this case occurred because we were able to intervene early in a growing child, before long-term tissue degeneration. Although it’s impossible to conclude from this single case if the sequential application of normobaric oxygen then HBOT would be more effective than HBOT alone, in the absence of HBOT therapy, short duration, repetitive normobaric oxygen therapy may be an option until HBOT is available." 
  
 Concluding, the researchers say that to their knowledge, this is the first reported case of gray matter loss and white matter atrophy (types of brain damage) reversal with any therapy and that treatment with oxygen should be considered in similar cases. “Such low-risk medical treatment may have a profound effect on recovery of function in similar patients who are neurologically devastated by drowning."

A:
When a 2-year-old girl in Arkansas managed to make her way through a baby gate and fall into the family swimming pool, she was submerged in 41-degree water for as many as 15 minutes before she was found. Having technically drowned and suffered a heart attack, Eden Carlson was resuscitated after the February 2016 accident but completely unresponsive to stimuli for a month. Now, in what appears to be a world first, per Newsweek, researchers at the LSU Health New Orleans School of Medicine and the University of North Dakota School of Medicine report in Medical Gas Research that they have managed to reverse much of her white and gray matter brain damage using two types of non-invasive oxygen therapy. "The startling regrowth of tissue ... occurred because we were able to intervene early in a growing child, before long-term tissue degeneration," says Paul Harch, who treated her, in an LSU release. MRI showed deep gray matter injury and both gray and white matter loss, and Eden was unresponsive, couldn't walk or talk, and constantly squirmed. Since researchers started giving her normobaric oxygen therapy (sea-level amounts of oxygen) and hyperbaric oxygen therapy (pure oxygen at higher pressure) for 45 minutes twice a day, she stopped squirming, appeared more alert, began to laugh, and can now talk, climb stairs, and play, reports USA Today. An MRI after her 40th HBOT session showed "near-complete reversal of cortical and white matter atrophy." "She’s getting so much better all the time," her mother says.
