In his youth, Dayton Wilson was a free spirit, an aspiring rap artist with a burgeoning talent at playing the electric guitar.

That all changed in September 2016, when a fentanyl overdose left him with brain damage.

Wilson's speech and balance were most greatly affected after the overdose.

His movements are as slow and deliberate as the way he talks. His vocabulary remains intact, but he speaks as though a recording of his voice is being played at half-speed.

Today it takes the 24-year-old a few moments to find the words he wants to say.

"Sometimes it's too loud. Sometimes I can't find an opportune moment to try to say [the right word]," Wilson said in an interview with White Coat, Black Art.

His hands often involuntarily clench into fists. He's likely permanently lost the dexterity that allowed him to play the guitar.
