During a 1992 TODAY interview with Katie Couric, the actress spoke candidly about her battles with bipolar disorder, referred to at that time as manic depression.

"Lithium [as a treatment] is not the be-all and end-all," Duke, who'd been diagnosed with bipolar disorder a decade earlier, told Couric. "It doesn't solve everything. You need to continue to work, some of us, until you sort out the other things and resolve as many as you can."

She said her mental illness had led to lapses in judgment, ranging from a marriage that lasted 13 days to asking two men she'd met in a parking lot to handle her finances.

"I choose to take responsibility for those things that I did, and I tried to not — you can't fix them," she added. "You can't buy back that time, but to certainly explain to the people who were so seriously injured emotionally and spiritually that there was something else going on. The best way is, once you start taking your medicine, if that works for you, is to change that behavior. And it's taken, oh, it's 10 years. It's thrilling for me to say 10 years of a healthy life."

Sean mourned the loss of his mother Tuesday afternoon on his public Facebook page, which posted a photo of a baby — likely Sean himself — in his mother's arms. "I love you mom," reads part of that photo caption.

That photo caption also linked to a website that's reportedly raising money for the Patty Duke Mental Health Project and a longer statement attributed to Sean Astin.

"Before her passing, before the suffering became too great, we talked about how the core mission of her mental health work might continue beyond her life," reads part of the statement on the crowd-sourcing page. "This initiative will fuel a multi-level approach to achieving results for those suffering with mental illness and their families and communities. Public awareness campaigns, lobbying efforts, and supporting a multitude of mental health programs big and small will be organized, prioritized and vigorously pursued."
