‘Star Trek’s’ Scotty has Alzheimer’s

James M. Doohan, the actor who played Scotty on the ‘60s “Star Trek” TV series, has been diagnosed with Alzheimer’s disease, his agent reports.

Doohan, 84, is in the beginning stages of the disease, a progressive neurological disorder that afflicted former President Ronald Reagan, Steven Stevens said.

Doohan, who lives in the Seattle suburb of Redmond, also has suffered for some time with Parkinson’s disease, diabetes and fibrosis, the latter due to chemical exposure during World War II when he was a soldier in the Canadian military, Stevens said.

Doohan’s career spans more than 50 years, but he’s best known for his role as the starship Enterprise’s affable chief engineer, Lt. Cmdr. Montgomery “Scotty” Scott, in the original 1966-69 “Star Trek” TV series. He also appeared in several “Star Trek” movies.

Doohan plans to attend a three-day “Star Trek” convention Aug. 28-30 in Hollywood, Stevens said, and is scheduled to receive a star on the Hollywood Walk of Fame on Aug. 31.
