(CNN) -- Bret Michaels' recovery from a brain hemorrhage suffered last week is going well enough that his concert tour could resume in a month, according to a statement on his website.
The rock singer and reality TV star suffered a massive brain hemorrhage and was hospitalized Friday.
"Even though yesterday was a minor setback, doctors remain hopeful for a full recovery and plan to release more specific information next Monday," his road manager Janna Elias said in the statement.
Tuesday's statement from Elias disclosed Michaels suffered a side effect from the brain hemorrhage called "hyponatremia, a lack of sodium in the body which leads to seizures."
Doctors sill have not pinpointed the "exact cause of the rupture" in Michaels' brain, she said.
"He is responding well to tests and treatments," Elias said.
Michaels, 47, was the lead singer for the '80s glam-metal "hair band" Poison. He became a reality star by headlining the VH1 show "Rock of Love with Bret Michaels." He has also appeared on "Celebrity Apprentice."
Elias said the plan is for Michaels' tour to resume May 26 in Fort Smith, Arkansas, "provided there are no further complications or setbacks."
The possibility Michaels could return to performing next month comes just six days after what has been described as a near-fatal attack.
"Doctors state Michaels is very lucky as his condition could have been fatal," Elias said Tuesday.
His full recovery could be months away, she said.
"With further testing and rehabilitation, they are hopeful that Bret will gradually improve as the blood surrounding the brain dissolves and is reabsorbed into his system, which can be a very painful recovery and take several weeks to months," she said.
Michaels is suffering slurred speech and blurred vision, according to earlier statements.
His manager and publicist have been careful not to disclose the hospital or even the city where the singer is being treated. They cite security reasons for the secrecy.
