INDIANAPOLIS, Ind. -- There is no cure for it, but this illness affects more than a million Americans.
A little boy in central Indiana is among the patients who suffer from hydrocephalus. Now, his family is working to help him and others understand the illness and end it.
Oliver McClellan wasn't even 2 years old when he first had symptoms.
"When Oliver was 18 months old he suddenly started having trouble walking," said his mother, Sarah McClellan. "We took him to the pediatrician, and they noticed his head had grown a lot since the last time we were there."
The concerned mother learned Oliver had hydrocephalus.
"It’s an abnormal accumulation of the fluid in the brain," explained McClellan. "We went from having this perfectly healthy little boy to within a couple days he was in the hospital having brain surgery."
There is no cure for hydrocephalus.
"There can be a lot of different causes," said McClellan. "It can be injury, infection. You can be born with it, and in Oliver’s case they found a small brain tumor that actually blocks the fluid."
So Oliver’s family started the Let’s Walk to End Hydrocephalus in Indianapolis in hopes of finding a cure.
"It's kind of crazy because there are over a million Americans living with this, yet hardly anybody has ever heard about it."
Hydrocephalus is most common in older adults, but can impact anyone just like Oliver. The walk is Saturday, Oct. 1, at Southeastway Park on Carroll Road in Indianapolis.
