Bella’s Story

Though brain injuries usually lead to a range of physical, cognitive, and emotional issues, every person who incurs a brain injury experiences a unique set of symptoms as well as both short-term and longer-term outcomes. This is true whether the brain injury is classified as mild, moderate, or severe. Therefore, it is important to take every brain injury seriously and to get medical attention as soon as possible to prevent further damage and to improve outcomes. Bella Kellis, at age 14, experienced a traumatic brain injury. In her own words, Bella, now 16, shares her story. 

From a very young age, I believed that prioritizing education and developing self-discipline was the key to success. At just five years old, I’d already fallen head-over-heels in love with school, I loved acquiring knowledge about the world and experiencing everything I could. That thinking was abruptly changed and put on hold when I was fourteen and sustained a traumatic brain injury.


It was mid-summer at Lake Murry in 2020. I was fifteen feet up in a pine tree, ready to use the rope swing to jump into the water, but things did not go as planned. Instead, I fell directly onto my head at the foot of the lake. At the time, my dad understood the potential severity of the accident and rushed me to the doctor, but they simply glued my lip together and sent me home. I walked out of urgent care with minimal bruising and no stitches. They assumed I was okay because I showed no apparent external physical damage beyond a torn lip, but what they didn’t see or understand was that I walked out an entirely different person. I thought maybe all I needed was some sleep and I’d wake up to the person I was before, but I was terribly wrong. 

"I was unpredictable, defensive & exhausted. I felt out of control and I knew I was a different person."

My sophomore year of high school started differently. Following the accident, I had multiple weekly emotional breakdowns and could not handle stress. I returned to school and found it almost impossible to stay awake in class (narcolepsy: a rare long-term brain condition that can prevent a person from choosing when to wake or sleep). I had always easily juggled sports, straight-A academics, friends, and family. However, I could no longer read without developing an instant headache. I felt abnormal anger, sadness, and mood swings daily. Maintaining healthy relationships was almost impossible.

By the end of my sophomore year, I was unpredictable, defensive & exhausted. I felt out of control and I knew I was a different person. My family could not comprehend how the girl who memorized her multiplication tables at age five was the same person sobbing over algebra 2, refusing to identify as a “math person” ever again. All of us were bewildered by the change. I spent the last two years rebuilding my academics, relationships, attending doctor appointments and therapies. Working to rebuild the life I once had is a struggle. The traumatic brain injury temporarily paused my development and left me trying to achieve what had been so simple before. I still face many obstacles in my day-to-day life, but I am making great progress. I have worked hard to compensate for the effects of my condition. It is an ongoing journey with plenty of adaptations, but the process allows me to know myself better than ever before.

Of the many struggles caused by my injury, I found the most detrimental was my loss of identity. When you cannot live your life as the person you once were, life as you know it, changes. Losing trust in yourself affects every area of your life, especially interactions with others. How can you build a strong bond with another individual if you do not have one with yourself? How could one accomplish simple, everyday tasks like communicating and reasoning with another person when the ability to communicate with myself was poor? My traumatic brain injury triggered a loss of self and disadvantaged me in every area of my life, including social, family, and academic settings.


My traumatic brain injury has transformed my attitude toward my accomplishments. It was a glimpse of reality, a reality of a world where we all have an expiration date, and in a split second, you could lose everything you have worked so hard for. All that stays with us is our experiences and those of the individuals we have impacted throughout our lives. Therefore, we don’t have time to waste on mindless activities that aren’t making a difference or bringing joy to our lives. Given the age of my injury, “brain plasticity” has allowed for what I believe is a miraculous brain recovery. However, I recognize that everyone does not share that fortune. I aspire to one day alter society’s current treatment and understanding of brain trauma by making that the focus of my studies in college and career beyond.

For the third consecutive year, the Dan Lewis Foundation for Brain Regeneration is proud to announce the DLF Prize competition. The 2025 DLF Prize, a $20,000 award, will recognize an outstanding early career scientist (2 to 5 years post-doc) conducting innovative research in neuroscience, pharmacology, or biotechnology. This prestigious prize honors researchers whose work aligns with the DLF mission to drive breakthroughs in neural regeneration and repair. The current research priorities of the DLF are: Pharmacological Reactivation of Neural Repair: Research into pharmacological methods of reactivating or augmenting synaptogenesis, neurogenesis or axonal repair. Cell-Based Cortical Repair: Investigating the potential of derived cortical neurons to restore function in damaged cortical regions. Transcriptomics of Neural Recovery: Characterizing transcriptomic profiles of cortical neurons in the recovery phase following brain injury to identify pathways that drive repair. Molecular Inhibitor Targeting: Advancing anti-sense oligonucleotides (ASO’s) or small-molecule therapeutics designed to downregulate inhibitors of neural regeneration in the cortex or spinal cord. Application for the 2025 DLF Prize can be made by going to our website— danlewisfoundation.org —and clicking on the Tab “ 2025 DLF Prize ”. This will bring you into the application portal. The application portal opened in March, 2025 and will remain open through May 31st. Once in the portal, you will find complete information about the DLF prize, eligibility requirements, and an application form which can be filled in and submitted online. The winner of the 2023 DLF Prize, Dr. Roy Maimon, continues his research indicating that downregulation of PTBP1, an RNA-binding protein, can convert glial cells into neurons in the adult brain (Maimon et al. 2024) .* Dr. Maimon, currently a post-doc at the University of California, San Diego is currently interviewing for a faculty position at several prominent neuroscience departments. The winner of the 2024 DLF Prize, Dr. William Zeiger is a physician-scientist in the Department of Neurology, Movement Disorders Division, at UCLA. Dr. Zeiger has expertise in interrogating neural circuits using a classic “lesional neurology” approach. He states, “Our lab remains focused on understanding how neural circuits become dysfunctional after lesions to the cortex and on investigating novel circuit-based approaches to reactivate and restore damaged cortex”. * Maimon, Roy, Carlos Chillon-Marinas, Sonia Vazquez-Sanchez, Colin Kern, Kresna Jenie, Kseniya Malukhina, Stephen Moore, et al. 2024. “Re-Activation of Neurogenic Niches in Aging Brain.” BioRxiv. https://doi.org/10.1101/2024.01.27.575940.

Alan was injured in 2021, at age 42. An art teacher in Lakewood, Colorado, Alan was riding his bicycle after school and was crossing at an intersection when a truck turned into the crosswalk area and hit him. Alan reports no memory of the event but has been told this is what happened. Alan says “My frontal lobe took the brunt of the impact, particularly the left frontal lobe”. Alan had a 2 ½ week stay at a nearby hospital where he, “re-learned to talk, to walk, and drink”-- although again he reports no memory of his stay there. Alan was then transferred to Craig Rehabilitation Hospital, in Englewood, Colorado. Alan says, “The only reason I knew I was at Craig is that I rolled over in bed and saw “Welcome to Craig” on the dry erase board.” During this stage of recovering, Alan repeatedly denied that he had been in an accident. Twice he tried to leave Craig on his own accord despite his wife’s and his therapists’ assurances that it was important for him to stay to recuperate from his injuries. Alan’s wife was 8 months pregnant at the time of his accident and gave birth to their son while Alan was an inpatient at Craig. Alan’s wife brought his newborn son to visit him days after the birth and Alan held him while sitting in his wheelchair, but Alan wistfully reports this is another thing he can’t remember. Alan reports that he still has significant difficulties with memory. Alan has also experienced several other neuropsychological difficulties. He states that for months after his injury, he could not experience emotion. “I could not laugh, I couldn’t cry.” Even after three years, his emotional experience is constricted. However, an emotion that is sometimes elevated is irritation and anger. Sometimes, dealing with people can be difficult because he may have temper flare-ups with little reason. This is something that Alan regrets and he is working hard with his neuropsychologist to improve the regulation of his emotions. Alan also has difficulty with organization, motivation, and distractibility. Earlier in his recovery, he had trouble sequencing and had difficulty carrying out personal and household routines. Alan has benefited greatly from therapy and his own hard work to make improvements in these areas. A chief reason that Alan works so hard in his recovery is so that he can be a good father to his son who is now almost 3 years old. He recognizes that it is important not to get frustrated when it seems that he can’t provide what his son wants or needs at a given moment. “I’m trying to raise my son the best I can…he’s at such a pivotal time in his life.” Alan’s financial situation was helped for a time by Social Security Disability Insurance payments but these payments ended. He is trying to get SSDI reinstated but the process of doing so is confusing and is taking a lot of time. Alan returned to work about 11 months ago at a liquor store (after about 2 years of not being able to work), the same store where he previously worked part time while teaching. He works in the wine department. “I sell wine and make recommendations.” When asked for advice to other brain injury survivors, Alan’s words were: “No matter how confused or upset you are or how frustrated you get, keep pressing on and moving forward because there is light at the end of the tunnel even though it may seem long. Keep moving forward and don’t give up no matter what anyone says to you”. Alan added that supports for individuals with brain injury are very important. He has found support groups, retreats, and seminars/events where brain injury survivors can share their experience to be very helpful. The volunteer work he does at Craig Hospital has been valuable for him. Alan is an inspiring individual. Despite having scarce memory of his accident and some confusion about the functional losses he has experienced, Alan has worked hard to make his recovery as complete as possible. He continues to work hard to progress and to express gratitude for those who have assisted him along the way.
