Their bodies were discovered in a vehicle parked off the side of the road, Fremont County Sheriff's Office told the Colorado Springs Gazette.

The car was parked near the Royal Gorge, which is roughly a three hour drive from their home in Denver.

The 33-year-old twins first rose to national attention when they appeared on the hit TV show The Doctors in 2017 to talk about the surgery they had in 2015.

The pair were the first people in Colorado to receive deep brain stimulation surgery to help what they described as debilitating symptoms of their disorder. 

No doctors from the CBS show were involved in the treatment or paid for it.

The Doctors issued a statement after the tragic news to express their sorrow at hearing of the twins passing.

“Amanda and Sara Eldritch appeared on The Doctors two years after their groundbreaking surgery to share their story of hope and newly-discovered happiness. We are shocked and saddened to learn of their tragic passing and our thoughts are with their family during this difficult time.' 

The surgery is most commonly used to treat tremors for Parkinson's patients, and involves electrode wires placed in the patient's brain. 

Those are then wired to two neurostimulators placed under their pectoral muscles, Denver DBS Center explained. 

During a 2017 appearance on The Doctors, Sara described the treatment as 'a little cloud of electricity that just pulses through your brain constantly.' 

Sara and Amanda once said the disorder felt like they were 'at war with their own existence'

Before their surgery the pair said they couldn't hold jobs, go to school, or even do something as simple as go see a movie

Sara and Amanda said the disorder felt like they were 'at war with their own existence'.  

They said each day they took 10-hour showers and rubbed their faces with hydrogen peroxide. They could use entire bars of soap just to wash their hands once. 

'They'd shower so long the water wouldn't drain fast enough, and would leak into the kitchen,' their mother Kathy revealed on the CBS show.  

They used so much peroxide, in fact, that their eyebrows turned orange from the chemicals. 

Sara and Amanda also said they went through 'five bottles a day' of rubbing alcohol on their skin.

They would then spend the rest of the day scrubbing and cleaning the bathroom.

Eventually the sisters said they lost all their friends as they continued to battle with the disorder. 

They tried everything from medications and traditional therapies to hypnotherapy, but nothing seemed to work. 

'If this is how our life is going to look like forever, there's no reason to live,' they once told their mother.  

That seemed to change with the deep brain stimulation surgery, which the twins said  in 2017 had alleviated many of their anxieties.

'Looking back at who I used to be, it seems like a different person that was just in my body,' Amanda said. 

'I was hijacked for 20 years and now I'm starting to get control back.'  

'We actually leave the house, we have friends, we go to concerts, we do things. We have a future,' she also said in a 2016 interview with 9News.

However, some of their fears, including public bathrooms, still persisted even after the procedure.

The twins have apparently been contemplating committing suicide since they were just 13.
