As Jeff Bezos pays tribute to his mum Jackie following her death, who are his siblings Christina and Mark?

Amazon founder Jeff Bezos has paid tribute to his mother, Jackie Bezos, who has passed away at the age of 78 following a battle with Lewy body dementia. According to the NHS, “Dementia with Lewy bodies (DLB), also known as Lewy body dementia, is one of the most common types of dementia. Dementia is the name for problems with mental abilities caused by gradual changes and damage in the brain. It's rare in people under 65.”

Symptoms of Lewy body dementia include hallucinations and hearing voices, problems with understanding, thinking, memory and judgement (similar to Alzheimer’s disease), confusion or sleepiness, slow movement, stiff limbs, tremors, disturbed sleep that can be associated with violent movements and shouting, fainting spells, falls, depression and anxiety.

Jeff Bezos shared a tribute to his mother Jackie Bezos on Instagram and wrote: “Her adulthood started a little bit early when she became my mom at the tender age of 17. That couldn’t have been easy, but she made it all work.

“She pounced on the job of loving me with ferocity, brought my amazing dad onto the team a few years later, and then added my sister and brother to her list of people to love, guard, and nourish. For the rest of her life, that list of people to love never stopped growing. She always gave so much more than she ever asked for.

“After a long fight with Lewy Body Dementia, she passed away today, surrounded by so many of us who loved her — her kids, grandkids, and my dad. I know she felt our love in those final moments. We were all so lucky to be in her life. I hold her safe in my heart forever.
