Every day in North Carolina, people experience sudden changes in memory, mood, behavior, or personality. Too often, these symptoms are treated only as mental health issues — while the underlying cause is brain injury that goes undetected.
The Brent Bill: Brain Health Screening and Safety Act is a statewide initiative to change that. It will eliminate a systemic "blind spot" and bias in the way medicine handles patients who appear to be having a "mental health" crisis. This bill will improve quality, safety and evidence-based mental health treatment.
This bill ensures that individuals in high‑risk populations — including law enforcement, first responders, veterans, athletes, domestic violence survivors and abused children receive timely, evidence‑based screening for brain injury and related medical conditions when they show sudden behavioral or cognitive changes.
Because early detection saves lives. Because misdiagnosis costs lives. Because North Carolina can lead the nation in brain‑health policy.
Officer Brent Simpson
You can read more about Brent's struggle in the New York Times.
Officer Brent Simpson served as a Police Officer for nearly two decades. He was known for his generosity, his humor, his work ethic and his unwavering dedication to his community. In early 2023, everything changed. Brent began experiencing sudden, profound shifts in memory, sleep, mood, and behavior. He told his wife, Gina, every day: “Something is wrong with my brain.”
He sought help. He followed medical advice. He underwent multiple MRIs, imaging, blood tests, months of inpatient treatment and evaluations by nearly every type of specialist. Yet no one screened him for brain injury. This condition was only discovered after his death. Brent is the first publicly known law enforcement officer diagnosed with Chronic Traumatic Encephalopathy (CTE). His story reveals a critical gap in our system — one this bill is designed to close.
Brent’s legacy will save lives. His story will protect others. His name will change North Carolina.
In 2023, researchers at Boston University released their findings after examining the brains of 152 athletes younger than 30 who died by suicide. Sixty-three (41 percent) had CTE, and of this group, 48 played football, but none higher than the college level.
Sudden behavioral change is often treated as a mental health issue — but many times, the root cause is neurological due to a physical injury to the brain.
The Data Is Clear
Up to 75% of domestic violence survivors have sustained a brain injury.
20% of high school athletes in contact sports sustain a concussion annually.
Over 450,000 U.S. service members have been diagnosed with traumatic brain injury (TBI) since 2000.
40–60% of incarcerated individuals have a history of TBI.
Law enforcement and first responders experience repeated head impacts during training and duty.
The Consequences of Missed Diagnosis
When brain injuries go undetected, individuals may experience:
Sleep disruption
Impaired judgment
Memory loss
Emotional dysregulation
Cognitive decline
Behavioral instability
Suicidal ideation
These symptoms are often misdiagnosed as psychiatric disorders — leading to ineffective treatment, worsening symptoms, and preventable crises.
The Brent Bill creates a tiered, medically responsible screening framework for individuals who present with sudden behavioral or cognitive changes.
Tier 1: Screening with low cost, validated tools.
Tier 2: Clinical Evaluation when Tier 1 indicates risk including Neurology, Neuropsychology, Physiatry and Behavioral health integration.
Tier 3: Diagnostics when medically necessary
Pilot Programs implemented in law enforcement agencies, veterans’ clinics, domestic violence service centers, school athletic programs and treatment centers.
Training for medical providers, first responders, DV advocates and school personnel.
Law Enforcement & First Responders: High exposure to head impacts, blast forces, and trauma.
Veterans & Military Families: Hundreds of thousands affected by TBI and blast exposure.
Domestic Violence Survivors: Up to 75% have sustained brain injuries.
Abused Children: Head trauma is common and often undetected.
Athletes: Youth, collegiate, and professional athletes face repeated impacts.
Individuals in the Criminal Justice System: High rates of undiagnosed TBI and cognitive impairment.
Families & Communities: Early detection reduces crises and improves safety.
Untreated brain injury can contribute to impaired impulse control and behavioral dysregulation. The Brent Bill strengthens public safety by ensuring that sudden behavioral changes are evaluated for brain trauma and neurological causes that might otherwise go undetected. This reduces behavioral emergencies, crisis‑driven law enforcement encounters and emergency room utilization. It supports law enforcement, first responders, families and communities.
Does this bill mandate imaging? No. Imaging is only used when medically necessary.
Does this stigmatize people with brain injuries? No. The bill focuses on early detection and support, not labels or predictions.
Does this increase insurance costs? No. Early detection reduces long term costs.
Who pays for screening? Insurance and Medicaid cover medically necessary care.
Is this a mental health bill or a public safety bill? Both. It strengthens public safety through medical accuracy and early intervention.
Why is this needed? Because brain injuries are often misdiagnosed as mental illness — with devastating consequences.
This will be too expensive. The bill uses a tiered model that prevents unnecessary imaging. Tier 1 screenings cost very little. Tier 2 and Tier 3 occur only when clinically indicated. Early detection reduces ER visits, hospitalizations, and crisis driven law enforcement encounters.
This will overwhelm neurologists. The bill includes pilot programs and training to build capacity. Most Tier 1 screens will not require neurology referral. Tele neurology can be integrated into pilot sites.
This medicalizes behavioral issues. The bill does not replace psychiatric care — it complements it. It ensures brain trauma is ruled out before psychiatric labels are applied.
This will increase insurance costs. Insurers already pay for crisis care, ER visits, and psychiatric hospitalization. Early detection reduces long term cost. The bill requires medical necessity for advanced diagnostics.

Robert Card (2023) - Axonal Degeneration
Mass Shooting / Suicide - Autopsy found significant "invisible" damage to nerve fibers likely caused by thousands of low-level military blast exposures.
Aaron Hernandez (2017) - Stage III CTE
Murder / Suicide - At age 27, he had brain atrophy and damage typically seen in individuals in their 60s. This is considered one of the most severe cases found in a young person.
Phillip Adams (2021) - Stage II CTE
Mass Shooting / Suicide - Autopsy revealed significant pathology in the frontal lobe, the region responsible for impulse control and judgment.
Chris Benoit (2007) - Advanced CTE
Double Murder / Suicide - His brain was described as resembling that of an 85-year-old Alzheimer’s patient due to repetitive wrestling-related trauma.
Charles Whitman (1966) - Glioblastoma
Mass Shooting - A small brain tumor was found pressing against his amygdala, the center for emotional regulation and aggression.
Junior Seau (2012) - CTE II
Suicide - One of several high-profile NFL suicides (including Dave Duerson and Ray Easterling) that spurred national conversation on the disease. Junior had no diagnosed concussions during his career.
Shane Tamura (2025) - Low-stage CTE
Mass Shooting / Suicide - At age 27, this represents significant and premature brain cell death. The damage was notably present in the frontal lobes, the area of the brain responsible for executive function, impulse control, judgment, and emotional regulation.
Wyatt Bramwell (2019) - CTE Stage II
Suicide - At age 18, the first case of stage 2 CTE to be diagnosed in a high school football player.
Jovan Belcher (2012) - CTE Stage I

Shane Christie (2025) - CTE (high stage)
Suicide - The 39 year old rugby player wrote, "Over the months of May to September 2023, I gradually exhausted my brain's energy and cognitive capacity, pushing myself to a point where I became delusional and paranoid. During a critical 12-day period in early to mid-September, I experienced four manic, psychotic events. These events not only exacerbated my symptoms but also became increasingly radical and difficult to comprehend."
