Overcoming Donald Sterling's lawsuit to retain the Los Angeles Clippers seems to be a cut and dried process for the NBA.

Should NBA punish Donald Sterling by giving back the Los Angeles Clippers?

TMZ Sports reported Thursday that Sterling failed a test that neurologists often perform on the elderly to check for the onset of dementia or other brain-related deterioration.

According to TMZ Sports, Sterling could not accurately put numbers on the face of blank clock. His medical records were submitted in a new court filing that TMZ Sports obtained. In the documents, two neurologists who evaluated Sterling in May detail the reason they think Sterling is incapacitated and incapable of running the Los Angeles Clippers.

TMZ Sports added the one of the neurologists, who has more than 20 years' experience, did "extensive testing" on Sterling and determined that the Clippers owner had "difficulties with the sequencing tasks of reverse spelling and serial subtraction."

Donald Sterling an unaware racist?

According to ageing.oxfordjournals.org, the clock-drawing test is used for screening for cognitive impairment and dementia, among other checks.

"Education, age and mood can influence the test results," the ageing.oxfordjournals.org document reads, "with subjects of low education, advanced age and depression performing poorly."

TMZ Sports did not clarify how badly Sterling misidentified the numbers, which could be used to determine the severity of the dementia.

Sterling has flip-flopped on whether to sue the NBA for enforcing a lifetime ban on him for racially insensitive comment he made about black people to V. Stiviano, whom Sterling claimed to be his girlfriend.

He first said he would sue the NBA to block the sale of the Clippers that his estranged wife Shelly directed to former Microsoft CEO Steve Ballmer. Then, Donald Sterling consented to let the sale happen but then changed his mind again earlier this week.

His mind-changing on the sale, in and of itself, does not suggest that his brain function has been compromised, according to ESPN.com.

"He's unsold his club several times over the years," NBA Commissioner Adam Silver said, as reported by ESPN. "There's well-noted incidents in the league when he was right there at a closing and at the last minute decided not to sell. And until he signs that document, we still have a pending litigation with him."

ESPN, however, identified another source that talked about Sterling's propensity to change his mind.

"Nobody doubts this thing will go through in the end. I guess it's just a matter of what mood Donald wakes up in tomorrow," one source close to the situation said.
