If doctors ultimately determine that a patient is a danger to himself or others, then he will be kept in a secure setting, allowed visitation by family members but kept behind locked doors, explains L.A.-based psychiatrist Dr. Charles Sophy.
"The next steps after the hold are when someone has come together, they're feeling better, they're then referred for outpatient treatment based on what was discovered during that hospitalization," Sophy tells E! News. (The doctor is not involved in West's case.)
A source told E! that Kanye was suffering from sleep deprivation—and Sophy says that it can happen at any age and it can cause behavior that resembles some of what West seemed to exhibit over the the past week.
"You're almost delirious," the doctor says. "You're punch-drunk, kind of, you're silly, you're talking, you're not making sense sometimes—you actually look like you may have a mental-health disorder to a major degree. [Like] you're psychotic even, you're hallucinating, seeing things, hearing things. But sleep and medication, sometimes, clears that right up. Sometimes I've seen it [cleared up] within 24 hours."
