Alice in Wonderland ' syndrome

Imagine how it would be like, when you have the feeling that you are trapped inside a room that’s far too small. As if you are a giant. Maybe funny when experimenting with some kind of hallucinating drugs. But pretty scary when it constantly seems like the world is just not big enough for you. The condition in which people perceive objects as much smaller than they actually are is called micropsia, or the ‘Alice in Wonderland Syndrome’ or the 'Lilliput sight'. The syndrome was first described in 1955 by the English psychiatrist John Todd (1914-1987). Todd named it, of course, for Alice's Adventures in Wonderland by  Lewis Carroll . Perhaps not coincidentally, Lewis Carroll suffered from severe migraine. Also known as a Lilliputian hallucination. Alice in Wonderland Syndrome  ( AiWS ), also known as  Todd's syndrome  or  dysmetropsia , is a disorienting neuropsychological condition that affects  perception . People may experience distortions in visual perceptio

Amygdala hijack

The  amygdala   is one of two almond-shaped clusters of  nuclei  located deep and  medially  within the  temporal lobes of the  brain  in complex vertebrates, including humans. Shown in research to perform a primary role in the processing of  memory ,  decision-making and  emotional responses  (including fear, anxiety, and aggression), the amygdalae are considered part of the Limbic system. Now the Hijacking part Amygdala hijack  is a term coined by  Daniel Goleman  in his 1996 book  Emotional Intelligence: Why It Can Matter More Than IQ .  Drawing on the work of  Joseph E. LeDoux , Goleman uses the term to describe emotional responses from people which are immediate and overwhelming, and out of measure with the actual stimulus because it has triggered a much more significant emotional threat. when the amygdala senses danger, it makes a split second decision and begins the fight-or-flight response before the cortex has time to overrule it. This cascade of eve

A Brave Heart: The Lizzie Velasquez Story

Eating whatever you want without gaining weight may sound like a dream, But it’s a daily battle for Lizzie velasquez . Elizabeth Anne Velásquez  ( born March 13, 1989) is an American  motivational speaker , author, and  YouTuber . She was born with an extremely  rare congenital disease  called  Marfanoid–progeroid–lipodystrophy syndrome  that, among other  symptoms , prevents her from accumulating  body fat  and gaining weight. Her conditions resulted in  bullying  during her childhood. During her  teenage  years, she faced cyber bullying, which ultimately inspired her to take up motivational speaking. Velásquez's condition is a very rare, previously undiagnosed and non- terminal  genetic disorder.Her condition bears similarities to many other conditions, especially  progeria . Medical researchers at the  University of Texas Southwestern Medical Center  previously speculated that it may be a form of  neonatal   progeroid syndrome (NPS) ( Wiedemann-Rautenstrauch syndro

"Prune head" / Brainy scalp

A man with a rare condition made the clinicians in Brazil scratch their heads after the skin on his scalp began to loosen and form the shape of a brain. His ailment has been identified as Cutis Verticis Gyrata,     and is a benign and essentially aesthetic condition. The soft folds that can count up to ten, typically affect the central and back regions of the head, but sometimes cover the entire scalp. The cause of the deformation remains a mystery in most cases. The condition is then classified as “primary CVG”. While it can be present on its own, the condition is often associated with other abnormalities, such as mental deficiency, epilepsy, schizophrenia, seizures, deafness and blindness. This patient has no symptoms of psychiatric or neurological disorders, but is intellectually impaired. “Secondary CVG” is caused by a disease, unbalanced hormones or drugs that lead to changes in scalp structure. For example acromegaly, a syndrome that results when the anterior pituitary

Papa smurf

We all feel blue once in a while, but some people actually are blue. This rare condition is caused by chronic ingestion or inhaling of silver. As a consequence, silver particles accumulate in the skin over time and darken with exposure to sunlight, resulting in an irreversible blue or gray skin tone. Argyria  or  argyrosis  is a  condition   caused by excessive exposure to chemical compounds of the element  silver , or to silver dust. The most dramatic symptom of argyria is that the  skin  turns purple or purple-grey. It may take the form of  generalized argyria  or  local argyria . Generalized argyria affects large areas over much of the visible surface of the body. Local argyria shows in limited regions of the body, such as patches of skin, parts of the  mucous membrane  or the  conjunctiva . In 2007, press reports described Paul Karason, an  American  man whose entire skin gradually turned blue after using  colloidal silver  made by himself with distilled water, salt

The curious case of Progeria

This is what a person looks like when they age 5 times faster than normal; the boy in this photo is only a child. The appearance of people with progeria can be described as small, wrinkled, and hairless with a frail, weak body and large head. Studies have shown that a person with progeria will have the body in a similar condition to that of an 80 year old by the time they are 15! People born with progeria rarely live past their early 20’s as their internal organs cease to function. Scarily, the condition is caused by a random genetic mutation, meaning anyone could potentially have a child with the affliction; fortunately there are only known cases in the world right now, so the chances are pretty slim. Researchers are hopeful that by understanding this condition they can unlock the secrets of the aging process. Progeria was first described in 1886 by  Jonathan Hutchinson . It was also described independently in 1897 by  Hastings Gilford .T he condition was later named Hutchinso

Rapunzel syndrome

Doctors find giant hairball in 12-year-old girl's stomach. Doctors have found a 250 gram hairball inside a 12-year-old girl’s stomach after she complained of pains. Schoolgirl Zhu Xiaoxin has since been diagnose with the rare condition called Rapunzel syndrome which is named after the 19th-century fairytale character created by the Brothers Grimm. Sufferers compulsively eat their own hair, which ends up mostly in their stomach while a ‘tail’ obstructs their small intestine. The schoolgirls’ parents told doctors at Lishui Central Hospital in eastern China that she had complained of stomach pains and had not had a bowel movement in four days. “CT scans showed a foreign mass obstructing her bowels,” the hospital’s head of paediatrics Doctor Zhang Heng said. “The obstruction was very obvious because her stomach contents could only be seen above and not below the object.” However, neither the girl nor her parents were able to recall her inge

World's shortest woman

  Jyoti Kisange Amge  is an Indian woman and actress notable for being the world's smallest living woman according to  Guinness World Records . Following Amge's 18th birthday on 16 December 2011, she was officially declared the world's smallest woman by  Guinness World Records  with a height of 62.8 centimetres ( 2 ft 0.6 in ). Her restricted height is due to a genetic disorder called  achondroplasia . Achondroplasia  is a disorder of bone growth that prevents the changing of cartilage (particularly in the long bones of the arms and legs) to bone. It is characterized by  dwarfism , limited range of motion at the elbows, large head size (macrocephaly), small fingers, and normal intelligence.  Diagnosis is generally based on symptoms, but may be supported by   genetic testing   if uncertain. Treatments may include  support groups  and  growth hormone therapy . Efforts to treat or prevent complications such as  obesity ,  hydrocephalus ,  obstructive sleep a
