- The girl who never aged
Brooke Greenberg died at the young age of 20 in 2013. But she didn’t look like your average 20-year-old because her body stopped developing at the age of five. Her hair and nails were the only parts of her body that continued to grow year by year. Despite being born premature, doctors remained perplexed as to why she stopped ageing. Numerous DNA studies showed no abnormalities in her genes associated with ageing. Nor did her parents have a history of abnormal development. Plus, all her sisters were normal and healthy. Scientists continued to refer to her condition as Syndrome X, a metabolic syndrome. Yet, her unusual condition remains unexplained by science.
On the other hand, here are 13 unsolved mysteries easily explained by science.
- Mermaid syndrome
Sirenomelia is a birth defect that partially or completely fuses the legs together, similar to how a mermaid looks, thus the alternative name “mermaid syndrome.” Most newborns don’t survive for long with this anomaly but some children defy the odds like Shiloh Pepin who lived until she was ten or Tiffany Yorks, the oldest known survivor of the condition, who died at age 27 in 2016. But the exact cause of sirenomelia is still unknown in the medical world because most cases occur randomly for no reason. Due to this randomness, researchers believe a new mutation or environmental factors may play a role in the development of the disorder.
- Highly superior autobiographical memory
If you give Jill Price a date, she can easily tell you what day of the week it fell on and what she did that day. Price was reported as the first known case of highly superior autobiographical memory (HSAM) in 2006. Since then, more adults and even children have been identified as having this ability. People with HSAM can recall almost anything from their memories in minute detail from events in their life to conversations they’ve had. The true mystery is why some people have this superhuman brainpower and others don’t. Brain images of people with HSAM have shown researchers that some parts of their brain structure are different from people who have a typical memory. But it’s not yet known if these brain differences cause HSAM or if they occur because the person uses areas of the brain associated with memory more.
Here are 15 more mysteries that have scientists perplexed.
- Water allergies
Fewer than 100 people in the world have been diagnosed with aquagenic urticaria, a rare condition where people break out in hives or rashes every time they’re exposed to water. However, researchers have not found an underlying cause for the condition. Some scientific theories suggest that the hives are caused by an allergen in the water or an interaction between the water and a substance found in or on the skin that generates a toxic material, which causes hives. Some doctors recommend patients only bathe in or drink purified water (that is, if the condition is allergen-based), but an effective treatment still has yet to come to fruition due to limited data on this rare condition.
- Stiff person syndrome
This rare, progressive syndrome known as stiff person syndrome (SPS) can cause people to experience extreme stiffness, rigidity and painful spasms in their muscles. Sometimes, these muscle spasms are so strong they can even fracture bones. When the central nervous system, specifically in the brain and spinal cord, has decreased inhibition, it can cause a person’s muscle activity to increase, which can result in SPS. Scientists think the syndrome may have an autoimmune component and research has indicated that it may occur when the immune system mistakenly attacks the brain and spinal cord. Although scientists are on the cusp of discovering what could cause this disabling disorder, they still have yet to understand everything about SPS.
Here are 6 myths about the human body quashed.
- Disembarkment syndrome
You know that feeling you get when you feel wobbly after you disembark a boat? You’ve probably heard someone say you’re “getting your land legs back.” For most people, this feeling of being in constant motion usually goes away after a few minutes or hours. But some people suffer from disembarkment syndrome, a condition where their bodies and brains can never shake that feeling of swaying and rocking. Unfortunately, it’s a hard condition to treat and usually goes away within a year. And it’s not just limited to being out on a boat either; riding in planes, trains, cars, even elevators can cause it too. Unfortunately, doctors still aren’t sure what really lies behind disembarkment syndrome. People who get migraines and women ages 30 to 60 are more likely to get it, but experts are uncertain if hormones play a role or how migraines could be linked.
- Morgellons disease
People with this skin condition typically feel like something is stinging or crawling all over their skin. Unfortunately, Morgellons disease is an uncommon skin condition, characterised by small fibres or particles emerging from skin sores, that modern medicine still doesn’t understand. Some doctors think the condition is all in the patient’s head and try to treat them with cognitive behavioural therapy, antidepressants, antipsychotic drugs or counselling, while others in the medical field think the fibres could be caused by an infection from the bacterium Agrobacterium, commonly found to cause tumours in plants. As researchers attempt to study the cause of this mysterious disease, there’s still no official guidelines on diagnosis and treatment.
- The boy who doesn’t feel hungry
In October 2013, Landon Jones, a 12-year-old boy from Iowa, U SA, suddenly woke up without an appetite or thirst. It only took a year for the boy to go from a healthy 47kg to a meagre 30kg. Doctors were baffled by his condition after countless brain scans, psychiatric evaluations and medical evaluations for digestive problems or eating disorders showed nothing. Some doctors wonder if he suffers from a rare brain dysfunction, particularly in the hypothalamus, the part of the brain that controls hunger and thirst. In 2014, his parents reached out to the National Institutes of Health to help evaluate Landon and possibly treat him for this rare disease. But there’s been no news to-date to say if doctors have determined a diagnosis.
