Why did Dellis first become interested in brain training?

Nelson Dellis first became interested in brain training because of his grandmother’s struggle with Alzheimer’s disease. Watching her gradually lose her memory and cognitive abilities had a profound emotional impact on him. As her condition worsened, she eventually struggled to recognize even close family members, including Dellis himself. This heartbreaking experience made him realize how important memory is to a person's identity, relationships, and quality of life.

After his grandmother passed away in 2009, Dellis became determined to learn more about how the brain works and whether memory could be strengthened through regular practice. He was particularly concerned about protecting his own cognitive health as he grew older and wanted to explore ways to reduce the risk of experiencing similar memory problems.

During his research, he discovered memory-training techniques and competitive memory championships. He was surprised to learn that many successful competitors did not possess extraordinary natural memory abilities. Instead, they had developed impressive skills through consistent training and specific memorization strategies.

This discovery inspired Dellis to begin training his own memory, eventually becoming a multiple-time USA Memory Champion. What started as a personal response to his grandmother's illness developed into a passion for demonstrating that ordinary people can significantly improve their memory through practice.

Ultimately, Dellis's initial motivation was not to win competitions or set records, but to understand memory, strengthen his brain, and potentially protect his cognitive abilities as he aged. His grandmother's experience with Alzheimer's transformed his understanding of brain health and inspired his lifelong dedication to memory improvement.
