In the days that followed, her memory kept resetting to that date every two hours.

When she would realise that’s not the date, she would go to her phone and find countless updates on her Notes app to fill her in on everything that’s happened since the accident.

“I have notes on my phone, when I got up this morning there’s like thousands of notes,” she told Fox News in an interview.

It turned out that Riley had suffered a severe concussion that other assessments had missed, and had a TBI (traumatic brain injury), affecting her ability to focus, prioritise and store information.

When Riley finally got that diagnosis from post-concussion specialists Cognitive FX, they were able to put together a plan to help her improve her memory.

Within just one week of treatment, Riley started making her first new memories – though she still hasn’t been able to recall anything that happened between 11 June 2019 and December 2019.

In the most recent update from her mom on the Facebook page Help Riley Remember over the summer, it was revealed that Riley will be a senior nursing major later this year and she spent her summer interning in Med Surge at a local hospital.

Riley is still on medicine for her seizures, and will probably never be her old self again, but her family haven’t given up hope and continue to search for a treatment that will work for Riley.

Though it’s been costly, Sarah says it’s been ‘worth every penny’ if it means helping her daughter get her life back.
