Nichelle Nichols, the actress who originated the role of communications officer Uhura in the original "Star Trek," suffered what her spokesman has called a mild stroke Wednesday while in her Los Angeles home.
The 82-year-old actress is "undergoing testing to determine how severe the stroke was," said Zach McGinnis of Galactic Productions LLC, which handles marketing and appearances for Nichols.
The news comes less than three months after her fellow cast mate Leonard Nimoy passed away following a yearslong struggle with chronic obstructive pulmonary disease.
The good news is that initial tests have come back negative for any major complications, although her family is still awaiting the results from an MRI, McGinnis told CNN Thursday night.
"Her right side has shown minor signs (of) mobility loss, but she is not showing any signs of paralysis," McGinnis said.
Other Trek actors and alum shared their thoughts and prayers through social media. George Takei, who originated the role of Sulu in the 1960s series, said he didn't hear the diagnosis, but was thinking of his co-star and friend.
We understand #NichelleNichols has been rushed to the hospital. We don't have any diagnosis on her condition but our thoughts are with her.

The American Stroke Association, a group associated with the American Heart Association, describes a stroke as when a blood vessel bringing blood and oxygen to the brain gets blocked or is ruptured. This can prevent the brain from getting the blood cells it needs, and is the No. 4 cause of death and a leading cause of disability in America.
Warning signs for stroke include sudden numbness or weakness in the face, arm or leg — especially on one side of the body; sudden confusion, or trouble speaking or understanding; sudden trouble seeing in one or both eyes; sudden trouble walking, dizziness, loss of balance or coordination; and sudden severe headache with no known cause.
Someone suffering from a stroke needs to get to a hospital right away since how quickly a stroke is treated can make a significant difference on its lasting impacts, the ASA says.
Up until her stroke, Nichols had continued to be a regular feature on the Star Trek convention circuit and is popping up in some independent productions like "The White Orchid" and the comedy "Unbelievable" with fellow Trek alum Marina Sirtis, Michael Dorn, Nana Visitor, Chase Masterson and Jeffrey Combs.
