What is kuru real name?

Kuru doesn't have a "real name" in the sense of a different word for the disease. Kuru is the name of the fatal neurological disorder.

The word "kuru" comes from the Fore language of Papua New Guinea, where the disease was first discovered. It means "to tremble" or "to shake," reflecting the main symptom of the disease, which is uncontrollable shaking.

So, "kuru" is the only name for this disease.
