Scariest Rare Diseases In The World
Many individuals worry they or their loved ones will fall victim to a rare medical disorder. Fortunately, the odds against this happening are significant. Fatal familial insomnia is the rarest of these diseases and the least manageable. This disease has no cure and always results in the death of the patient. Noma cancrum oris, or a gangrenous infection of the mouth and face, happens only under certain conditions and can be prevented with proper hygiene. Polyglandular Addison’s disease is rare and can be detrimental to a patient’s quality of life, but it is manageable with modern medicine. Leprosy also joins the ranks of illnesses that are rare and frightening but can be successfully treated. Children with Harlequin ichthyosis are not as fortunate: their sad condition is permanent and only supportive care is possible. These five diseases have fascinating histories.
Fatal Familial Insomnia
This disease is extremely rare, affecting only a handful of families around the world. Fatal familial insomnia is a prion disease, meaning it stems from malfunctioning proteins in the nervous system. These proteins become infectious, killing neurons in the brain. In this disease, the thalamus is most affected. This disease most commonly appears at midlife, around forty years old. Patients first experience insomnia that worsens over time. The patient may have phobias and panic attacks, developing into hallucinations, and eventually, the patient loses the ability to sleep. Patients also experience sweating, a rise in blood pressure and heart rate, and constipation. Symptoms gradually deteriorate into dementia, where the patient gradually loses control of their body and mind. Most patients succumb to the disease between seven months and four years after diagnosis.

Noma Cancrum Oris
Noma cancrum oris destroys the gums, mouth, and facial areas of its unfortunate sufferers. The disease produces gangrenous lesions on the face, on the gums, and inside the mouth. The disease is endemic to sub-Saharan Africa, where it affects up to seven per one thousand people. The disease most often strikes children between two and sixteen. Acute gingivitis is thought to be the precursor to the disease, and secondary bacterial infections cause the gangrene. Poverty, poor oral hygiene, and malnutrition play important roles in determining who gets this disease. Infectious diseases like measles and the oral herpes virus also play a part. Being close to livestock in unsanitary environments can exacerbate the disease.

Polyglandular Addison's Disease
Polyglandular Addison's disease includes autoimmune adrenal insufficiency, autoimmune hypothyroidism, and type 1 diabetes mellitus. Adrenal insufficiency means the body is not producing enough of two hormones: cortisol and aldosterone. All of these syndromes together take on the name Schmidt syndrome or polyglandular autoimmune syndrome type II. This disease produces overwhelming fatigue, hypoglycemia, weight loss, and changes in the pigment of skin and gums. Patients may also experience dizziness, nausea, vomiting, and salt cravings. This disease often occurs in family clusters and is more deadly in young patients, though with proper treatment, polyglandular Addison’s disease can be managed. When the disease comes on suddenly, it can result in acute adrenal failure.

Leprosy
Leprosy, a bacterial infection, affects the nerves and skin. Today, it is known as Hansen’s disease. The disease is disfiguring, causing a great deal of fear, and has a long history in human populations, with strict controls placed on patients in historical times. In historical times, the vast majority of individuals feared leprosy was far more contagious than it actually is. This disease is caused by Mycobacterium leprae, a slow-growing bacteria, and produces severe skin lesions and sores as well as nerve damage. Fortunately, this disease can be cured with modern antibiotics. Today, leprosy does not have to be a life sentence.

Harlequin Ichthyosis
Harlequin ichthyosis is a rare genetic disorder affecting newborn babies. When a child with this condition is born, their skin is formed in thick, hardened plates, and between the plates, there are deep fissures. Babies with harlequin ichthyosis have become more likely to survive in recent years, but it is a devastating diagnosis. Children with this condition have problems with dehydration as well as secondary infections. Their fissured skin does not form a barrier between their body and the outside world. Fortunately, this frightening genetic disorder happens in only one out of every 300 thousand births, and only two hundred cases have been reported.
