When it comes to rare diseases, true strength isn’t measured by physical force, but by one’s courage, resilience, and perseverance.

Understanding the Challenge

People with rare diseases, and those who support them, are often overlooked because their conditions are misunderstood or little is known about them. Even reaching a diagnosis for a rare disease can be a long and frustrating experience. The average time from a person’s first symptom to an accurate diagnosis is approximately five years, and for some people it can take up to 20 years.25 They’ll typically visit more than seven physicians, on average, before receiving an accurate diagnosis, so they must possess a mental toughness and a spirit that screams, “I refuse to be ignored!” 25

It can be difficult to get to the right diagnosis for a rare disease, as aHUS, gMG, HPP, LAL-D, PNH, and other rare diseases often resemble different, more common conditions. It can take many doctors, many appointments, and sometimes many years to figure out what is wrong.
