top 10 rare diseases

Today, 28th February 2022 marks the 14th annual Rare Disease Day, a day specifically reserved to spread awareness regarding the unusual diseases in the world.

Rare diseases refer to diseases that affect a very small percentage of the population. They fall under a wide variety of symptoms and disorders that differ from disease to disease as well as patient to patient suffering. 80% of the conditions have a genetic origin whereas the rest may be caused by allergies, infections, or environmental factors.

Every year, Rare Disease Day is sponsored by the NIH to raise awareness about rare diseases among the masses as well as policymakers. This year the global theme for Rare Disease Day is: “Share Your Colours.”

Let’s talk about the top 5 rare medical conditions that are present around the world.

1. Alice in Wonderland Syndrome

This syndrome has been named after Lewis Carroll’s book i.e. similarly titled. This rare disease, with a prevalence of 10-20%, is associated with migraine and the sufferer perceives objects to be far smaller than they are. This condition can also affect touch, hearing, or even the perception of their image.

2. Morgellons

In this rare medical condition, thread-like blue or black fibers appear under the skin accompanied by stinging, crawling, and biting sensations.

Nearly 14,000 people suffer from this illness that is also characterized by memory impairment, changes in vision, and joint pain. Amongst the medical professionals, this condition is famous as the ‘fiber disease’ and there is no known cause behind it.

3. Foreign Accent Syndrome

Of this interesting disease, there are only 60 recorded patients. Patients of this syndrome have a speech disorder so that native speakers talk in a manner that is perceived as a ‘foreign accent’.

Early on, this was dismissed as a psychological problem by the doctors; however, later research in the UK revealed that people suffering from this had similar abnormalities in their brain anatomy. This disorder may result from trauma, stroke, or even multiple sclerosis.

4. Laughing Death or Kuru

This incurable disease is almost completely eradicated, however, it is important because it has greatly impacted scientific research. This rare medical condition occurred in the 1950s due to the practice of cannibalism on corpses in New Guinea.

The symptoms of Kuru included bursts of maniacal laughter, as well as shaking limbs, inability to retain balance, and eventually death within a year. It resulted in a “swiss-cheesing” of the brain, which was the term used to describe the holes that emerged in the brain of the deceased patients.

5. Water Allergy

Another rare medical condition, with about 30 reported cases, is that of water allergy or aquagenic urticaria. This condition occurs more commonly in women and may be associated with hormonal imbalance. Although the exact cause is unknown, it may be a hypersensitivity reaction to the ions present in non-distilled water.

You may be suffering from these or some other medical conditions. In such a case, it is critical to get proper medical consultation.
