Bad Brains singer Paul "H.R." Hudson has been diagnosed with a rare neurobiological disorder known as 'SUNCT' that causes extreme, crippling headaches.

Hudson's wife Lori announced the news with the launch of a GoFundMe campaign to help raise $30,000 for treatment at a headache center not covered by their health insurance.

In an accompanying statement, Lori wrote: "There is no known cure and no reliable medical treatment. To give you an idea of what he’s dealing with, cluster headaches are nicknamed ‘Suicide Syndrome.’"

She said the headaches occur randomly and with no warning at any hour but H.R.'s are worse at night. "The intensity of the nighttime headaches is so great that he yells, cries out, groans, and sobs — repeatedly, every few minutes, for most of the night. He can’t work. He has no quality of life. If you call him and ask how he is, he will say, ‘Everything’s okay,’ because that’s just how he is. But everything is not okay."

This is the second major health issue to hit Bad Brains during the past year. Guitarist Gary Miller (aka "Dr. Know") suffered a heart attack last November and his condition quickly progressed to multiple organ failure. He was on life support for nearly two weeks and was hospitalized for almost three months before he was transferred to a medical rehabilitation facility.

Bad Brains recently posted a video of the band performing "I" from their self-titled 1982 debut. Check it out below.
