Trotter was found dead in his home Wednesday. He was 54.
An autopsy conducted Thursday proved inconclusive and the cause of his death has been deferred until the results of toxicology tests are complete.
"In January, Charlie was treated for a seizure as a result of an aneurysm, which was discovered at that time," Rochelle Trotter said in a statement to the Chicago Tribune Friday.
"His doctors prescribed the proper medication to control seizures, his blood pressure and high cholesterol, and he was seen by a number of medical experts, who cleared him to travel," the statement said. "He returned home from his most recent trip Monday night without incident. The autopsy indicates that his travel is not connected to his death.
"This is obviously a difficult time as we are still processing our grief. As his family and I focus upon putting Charlie's body to rest, we hope that this will settle the inaccuracies that have been reported and we can move forward in honoring Charlie's life on Monday. We ask for your patience and continued respect of our privacy."
