I often see my father with his head in his hands induced by a quiet spell haunted by the pain of his mother whom he repeatedly says is slipping away because of her dementia. "She's slowly disappearing," he says. I didn't know my grandmother until I was about 15 years old. She had just lost her husband of 60 years to a severe case of diabetes. She was alone and needed comfort from the nearest family she had, so she came to live with us. When I was young I thought it was irritating how she would consistently and only repeat the same three stories about my dad and how he loved examining her car when he was five years old, the story of how she wrote a letter to Barack Obama, and how she loved making paper flowers for her coworkers when she was younger. My dad said she used to be the sharpest, strongest woman he knew, and she was never like how she is now. All I saw was the repetition. Over time, I began to understand. Through her stories, though repeated, she held her family, her freedom, voice, and creativity close to her heart. It was heartbreaking to see my dad lose a part of his mother, but I was fascinated by the inner workings of the brain. My grandmother kept her identity through three random life stories yet couldn't remember my name or where I lived. During COVID-19, I was fortunate to receive a position at a lab where I was able to learn about the use of stem cell therapies to better understand Alzheimer's disease and dementia. My specific project was to understand the effect of paraquat, a toxic chemical and pesticide, on the brain and how it is commonly associated with triggering early-onset Alzheimer's and dementia. This research kickstarted my interest in the fascinating subject. When 60 Minutes released an episode about a large population of central South Americans who were contracting the disease in their early 30s, I dove deeper into the research. From a research perspective, it was exciting to see the parallels between the pesticide paraquat and South American farmers contracting Alzheimer's.
Moreover, it was fascinating how the brain can change so drastically in such a short period, but also to never know what specifically triggers the onset of these neurodegenerative diseases in specific cases. There is also no standing cure. As I sat in on a Front Row talk at Scripps Institute this past summer, I listened to Jeffery Kelly give a presentation on how the alteration of gene formation can increase the risk of neurodegenerative diseases and how genetic editing and bioconstruction of new genes can serve as a prolonged preventative treatment for those who are "at risk." The presentation opened the door for new questions and curiosities for me. Who is "at risk" if only a handful of reasons for Alzheimer's onset are known? Is anyone sampling large groups of people and their genetic formation to assess the likelihood of getting dementia or Alzheimer's from youth to present to track societal, genetic, and environmental factors en masse? It's scary to imagine that one day I could be like my grandmother, and in less than a year, everything I ever knew was taken away from me. As I pursue my bachelor's degree and dream of obtaining an MD/PhD with a background in Biomedical Engineering and Global Health, I keep my interest in understanding and working with neurodegenerative diseases close at heart because one day I will contribute to this worldwide challenge of finding a cure. One day, It will happen, and I want to be there when it does.
