SHREVEPORT, LA (PIX11) — A Louisiana boy born without a brain died last week at the age of 12, according to KSLA.

Trevor Judge Waltrip was born with a rare condition called hydranencephaly, with sacs filled with cerebrospinal fluid taking the place of his brain’s cerebral hemispheres.

Trevor had a brain stem that allowed him to breath, have a heartbeat and respond to some stimuli, though he couldn’t talk or see.

Doctors say Trevor surpassed expectations and it was rare that he lived past 12 weeks, let alone 12 years, KSLA reported. He died in his sleep on Aug. 25.
