Rev. Jesse Jackson announced he has Parkinson’s disease in a statement on Twitter Friday.
Jackson, 76, said that the diagnosis came after he began finding it “increasingly difficult to perform routine tasks.”
“My family and I began to notice changes about three years ago,” he said.
He said he resisted seeing a doctor so as not to interrupt his work, but finally gave in after his “daily physical struggles intensified.”
“After a battery of tests, my physicians identified the issue as Parkinson’s disease, a disease that bested my father,” the reverend said in the announcement on his health.

He explained how he has struggled to accept the implications of his diagnosis.
“Recognition of the effects of this disease on me has been painful, and I have been slow to grasp the gravity of it,” he said.
But he vowed to press through the disease to the best of his ability.
“For me, a Parkinson’s diagnosis is not a stop sign but rather a signal that I must make lifestyle changes and dedicate myself to physical therapy in hopes of slowing the disease’s progression.”
He said he will also dedicate his remaining years to help find a cure for the disease affecting 60 million Americans every year.
He said he will also continue writing a memoir.
“I steadfastly affirm that I would rather wear out than rust out,” he said.
