20 Of The Weirdest And Rarest Diseases Known To Mankind

Alien Hand Syndrome

Alien Hand Syndrome is an incredibly rare neurological disease that causes random hand movements without the individual knowing what is happening or having any control. The person can reach for objects and manipulate them without them knowing about it. Unfortunately, there is no known cure for Alien Hand Syndrome. Symptoms can be reduced and managed, however. Holding an object within the affected hand can help a great deal.

Lymphatic Filariasis

Lymphatic Filariasis, also known as elephantiasis, is caused from a parasitic worm. Cases of the disease have no symptoms at first, though individuals ultimately develop massive amounts of swelling in the arms, legs, or genitals. Skin becomes thicker, and pain can occur. Treatment is available in some cases, including antibiotics to deal with infection.
