Alzheimer's may soon be treated with HIV drugs. "Immediate clinical evaluation of HIV antiretroviral therapies in people with Alzheimer's disease [is warranted]," say the authors of a recent study.

Thatstudy, published in Nature, on Alzheimer’s disease provides new details of how the disease may originate. It goes on to propose that HIV drugs could immediately be repurposed to treat Alzheimer’s, The San Diego Tribune reported.

The article points out elderly HIV patients, who have been treated with HIV drugs for decades, almost never get Alzheimer’s.

“Let's say this only works 25 percent of the time, that's still 1.5 million patients in the United States, not to speak of their families,” said Jerold Chun, lead author of the study. 

Doctors could use the HIV drugs on Alzheimer’s patients as an “off-label” use, Chun said. But that would require careful ethical consideration.
