A 5-year-old boy has a rare brain condition that could cause him to be literally scared to death, according to news reports.

Reed Havlik, who lives in Iowa, has a condition called vanishing white matter disease, a disorder that's been reported in only about 200 people worldwide, according to South West News Service (SWNS). Vanishing white matter disease is a genetic condition that mainly affects the brain and spinal cord, and causes deterioration of nerve fibers known as "white matter," according to the U.S. National Library of Medicine's Genetics Home Reference (GHR).
