A groundbreaking study led by researchers at the University of Calgary has shown that brain shunt surgery can dramatically restore mobility and independence in older adults suffering from idiopathic normal pressure hydrocephalus (iNPH) -- a condition often mistaken for dementia or the natural effects of aging.

The clinical trial, which involved 99 participants across 17 sites in Canada, the United States, and Sweden, was stopped early after researchers observed significant improvements in patients who received shunts.

The procedure involves inserting a small device to drain excess fluid from the brain, relieving pressure and restoring function.

Dr. Mark Hamilton, a neurosurgeon and lead investigator, says the results speak for themselves.

"I've had some patients who were bed-bound or unable to get out of a wheelchair. After surgery, they're walking again -- without falling," said Hamilton. "Their independence returns, and even incontinence improves, which is a major quality-of-life issue."

One of those patients is 79-year-old Jill Knaus, who was diagnosed with hydrocephalus after experiencing severe mobility issues and loss of bladder control. She received a shunt in June 2024 and says her life has completely changed.

"We walk about seven kilometres a day up and down hills," said Knaus. "I live on my own, I'm independent. I drive a car now -- something I couldn't do before."

Researchers warn that untreated iNPH can lead to severe neurological disability and even early death.

The study's findings were published in the New England Journal of Medicine, marking a major milestone in the treatment of a condition that has long been misunderstood.
