Danny Bonaduce to undergo brain surgery for neurological disorder and hydrocephalus diagnosis.

Danny Bonaduce, the radio host and former child actor, is set to undergo brain surgery to treat his recent diagnosis of hydrocephalus, a neurological disorder that results in fluid in the brain. Bonaduce, who is currently unable to walk, will have a stent and a drainage port placed in his brain. He has met with numerous doctors before receiving the diagnosis and is unsure of what caused the illness. The surgery is expected to improve his condition by 50%, but Bonaduce is not expecting a full recovery.
