Dr. Dre addresses brain aneurysm diagnosis for the first time.

Dr. Dre reveals what he thought when he was first diagnosed with a brain aneurysm, as he insists he was in good health earlier this year.

The 56-year-old hitmaker was rushed to Cedars-Sinai Medical Center in Los Angeles, after suffering a terrifying health scare in January, amid his stressful divorce with his ex-wife Nicole Young.
