Sheryl’s Story
Dan Lewis Foundation | Spring 2024

Sheryl Suzanne Nibbs, a legal secretary in a top law firm, started the process of becoming a paralegal as she approached her 40th birthday. She was fancy in her appearance, always making sure her hair, nails, and clothing were in order, a well-kept person, an avid traveler, and her mother’s best friend. Sheryl celebrated her 40th birthday in December 2007.  It was a grand celebration.  Sheryl danced the night away with her family and friends.  At the party, I recalled my sister stating, “I planned this party because I don’t know what next year holds, so I choose to celebrate my life today in great style.” Sheryl could not have known nor expected what the following year would hold.


On December 3, 2008, Sheryl planned to do something quiet for her 41st birthday, simply choosing to go out with friends.  A few days later, one of the coldest days in December 2008, Sheryl was scheduled for a laparoscopic procedure. Her surgery was supposed to be a simple outpatient procedure. Sheryl arrived home several hours after the routine procedure. Unfortunately, the nightmare that eventually led to Sheryl’s traumatic brain injury was just about to unfold. Sheryl started experiencing excruciating pain and was rushed to the hospital. On Thursday, December 8, 2008, the family learned that she had a perforated bowel. Her diagnosis led to emergency surgery to repair her perforated bowel.

The surgery was deemed successful, but while in recovery, her blood pressure dropped dramatically, and she experienced cardiac arrest. Sheryl sustained a traumatic brain injury during this event. Little did we know, my sister, as we knew her, would be no more. The person we once knew was gone. Everything about Sheryl’s life changed: her appearance, her gait, and most of all, her memory. My sister’s life, what we once considered “normal,” was gone. She was no longer looking forward to going to the job that she loved, running around shopping, dancing, and continuing the life she had built for herself. Sheryl’s family’s life changed as well. Our family was challenged with medical and rehabilitation challenges and obtaining guardianship through court appearances and dealing with multiple lawyers. It was a nightmare! 



Today, 16 years later, Sheryl’s sister, brother, and nephew remain her backbone. She requires 24-hour care and has several caregivers because her cognitive skills are minimal. We try our best to keep her active. She attends social events; we take her on day trips during the summer and spend time as a family. It’s a difficult situation to see your loved one change in an instant. She might be different in appearance and abilities, but she is our sister, and we are grateful she is here with us. Our experience and the change required from all family members is difficult to understand, except for those who live it.

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 ”. Once in the portal, The application portal is open from March 1st through May 31st. This portal will open on March 1, 2025. 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.
