The Jonas Brothers feel "proud" of their "superhero" mother after she opened up about suffering a stroke.

Denise Jonas - who has Joe Jonas, 36, Nick Jonas, 33, Kevin Jonas, 38, and Franklin Jonas, 25, with her 61-year-old husband, Kevin Jonas Sr. - recently suffered the medical trauma, and her sons have praised her for talking about her ordeal.

During a joint interview with Kevin and Nick, Joe told E! News: "She went through quite a journey, and we're proud of her that she feels comfortable talking about it.

"I'm sure that will encourage a lot of other people out there."

Kevin also heaped praise on his mother for teaching him and his siblings how to "respect women".

He added: "She's a very strong woman, and someone that's amazing to look up to our whole life, and learn how to not only act around women, but also how to respect women.

"Our mom is our superhero, so I feel like we try to celebrate her every time we're with her or away from her."

Nick said: "We've spent a lot of important days away from our very understanding and loving powerhouse women in our lives.

"So it's incredible to have that support system going back to our childhood with our mother."

Ahead of Mother's Day in the US, on Sunday, May 10, the Jonas Brothers recalled cherished childhood memories with their mom, including "sitting on the couch laughing and just enjoying one another", and "eating anything" Denise cooked for them.

Earlier this month, Denise opened up about suffering a stroke.

She sometimes cannot speak clearly after a group of brain structures that control cognitive functions were impacted by the medical emergency, caused by reduced blood flow to the brain.

Speaking on Jennifer Vickery Smith's Got It From My Momma podcast, Denise said: "It was what you call a basal ganglia [because] it was in the basal ganglia area of my brain, which affected my cognitive thinking, my speech [and] reasoning.

"At certain times, I would have difficulty with my speech.

"If I'm tired or hungry, I can fumble my words around and not think of the right words. Sometimes I can't remember if it's this or that, and I really can't."

Denise - who did not reveal when she had the stroke - had no idea she experienced "prior symptoms" before she was diagnosed.

The 59 year old explained: "I was at home [and] the symptoms that I had were that my blood pressure had been high. I had gone to three different doctors over the course of six months prior … and I woke up feeling like my arms are weird. It's terrible, but it's the only way I can describe it."
