Can repetitive head impacts and explosive blast exposure affect your mental health even when you don't realize you've suffered a brain injury?

In this solo episode of the Broken Brains Podcast, Bruce Parkman explores the relationship between repetitive brain trauma, concussions, mental health, and the importance of recognizing brain injury before symptoms become more difficult to manage.

Bruce discusses the warning signs of concussion, the neurological effects of repetitive head impacts, and why military veterans exposed to explosive blasts and athletes participating in contact sports should take brain health seriously. He explains how injuries involving the prefrontal cortex may contribute to changes in emotional regulation, behavior, and cognitive functioning.

The conversation also examines concussion evaluation, neuroinflammation, the developing brain, youth sports safety, and why early medical assessment and prevention are essential.

This episode provides practical education for veterans, parents, coaches, athletes, and families concerned about traumatic brain injury, concussion symptoms, repetitive brain trauma, and long-term neurological health.

Can an undiagnosed brain injury contribute to behavioral, emotional, or mental health problems in children?

In Episode 110 of the Broken Brains Podcast, Bruce Parkman sits down with Dr. Melissa McCart to explore the connection between childhood brain injury, concussion, trauma, mental health, and the importance of recognizing potential brain injuries early.

Dr. McCart discusses her work identifying brain injuries in children and youth, including the development and implementation of the Rapid Alaska Brain Injury Screening Tool (RABIST). She explains why changes in behavior, learning, emotional regulation, or mental health can sometimes signal the need to investigate a history of brain injury.

Bruce and Dr. McCart also explore concussion management, contact sports, domestic abuse, school accommodations, non-pharmaceutical interventions, family support, and practical questions parents can ask when something about their child suddenly seems different.

Episode 110 is an important conversation about recognizing brain injuries earlier and building systems that support children before potentially manageable problems become lifelong challenges.

What can the NFL’s evolving approach to player safety teach parents, coaches, and youth sports organizations about protecting the developing brain?

In this solo episode of the Broken Brains Podcast, Bruce Parkman examines football, concussions, repetitive head impacts, and the ongoing effort to reduce brain trauma in contact sports. Bruce discusses recent NFL safety measures and what those changes reveal about the growing focus on reducing unnecessary head impacts.

The conversation then moves beyond professional football to the athletes Bruce believes deserve even greater attention: children and teenagers. He explores why repetitive head impacts matter, how the developing brain differs from the adult brain, and why delaying contact may be one strategy for reducing cumulative exposure during childhood.

This episode examines football safety, youth sports, concussions, repetitive brain trauma, player safety, mental health, and practical ways parents, coaches, and sports organizations can think differently about protecting young athletes.

What happens when people searching for relief through psilocybin face legal, regulatory, and financial barriers to accessing it?

In Episode 109 of the Broken Brains Podcast, Bruce Parkman sits down with psilocybin advocate Spencer Hawkswell to explore psychedelic medicine, mental health, end-of-life care, brain health, and the fight to expand legal access to psilocybin in Canada.

Spencer shares the personal story that led him into advocacy and explains how patients and advocates have challenged Canada's psychedelic drug policies through medical exemptions, the Special Access Program, public advocacy, and continued pressure for reform.

Bruce and Spencer also discuss the psychedelic therapeutic process, including preparation, the psychedelic experience, and integration; barriers to clinical research; veteran mental health; trauma; neuroplasticity; and emerging questions about whether psychedelics could eventually have applications in traumatic brain injury and repetitive brain trauma.

The conversation examines both the potential and the unanswered questions surrounding psychedelic medicine while exploring what safe, legal, medically supervised access could look like in the future.

Can a supplement, helmet, mouthguard, gummy, or new technology actually prevent a concussion?

In this solo episode of the Broken Brains Podcast, Bruce Parkman challenges concussion-prevention claims surrounding contact sports and explains why parents should be skeptical of products marketed as protecting the brain from the forces created by repetitive head impacts.

Bruce discusses how the brain moves inside the skull during impacts, the difference between reducing certain risks and claiming to prevent brain injury, and why repetitive head impacts remain an important concern in youth contact sports. He also examines supplements and other products marketed around brain protection and argues that no pill or product can eliminate the physical forces acting on the brain.

The episode explores concussion prevention, repetitive head impacts, CTE, youth sports safety, the developing brain, and alternatives such as flag football and touch rugby for families looking to reduce exposure to repetitive impacts.

What happens to the brain after years of blast exposure—and what options exist when conventional approaches aren't enough?

In Episode 107 of the Broken Brains Podcast, Bruce Parkman sits down with Mark Kingsboro to discuss his military service, exposure to blasts during route clearance missions, and the physical and psychological struggles that followed him home.

Mark shares his journey through mental health challenges and self-medication before discovering a broader approach to brain health that included hyperbaric oxygen therapy, transcranial magnetic stimulation, nutrition, sleep, exercise, and other interventions.

Bruce and Mark explore repetitive blast exposure, PTSD, traumatic brain injury, barriers to diagnosis and treatment, and why addressing veteran brain health may require looking beyond symptoms toward the underlying physical, psychological, and lifestyle factors affecting recovery.
