For many years, as a founder and investor, I’ve worked alongside teams in mental and behavioural health and addiction treatment. Through that work, I developed a simple but powerful idea: the connections in our brains — how well signals travel between the parts of us that feel, the parts of us that think, and the parts of us that decide — shape how well we handle life’s hardest moments. When those connections are strong, there’s more space between what happens to us and how we respond to it. When they’re weakened, damaged, or underdeveloped, that space collapses, and overwhelm arrives faster and stays longer.
I believe this same principle applies directly to grief — and I believe it may help explain something many people describe but rarely have language for: the sense that grief today feels harder to move through than it “should”, even when we do everything we’re told is supposed to help.
Neuroscience research on grief specifically supports part of this picture: grief engages attachment, memory, and emotion-processing circuits throughout the brain, and prolonged or complicated grief has been associated with impaired connectivity in regions responsible for emotional regulation and integrating loss into an updated sense of life going forward.
The reasons neural connections end up broken, damaged, missing, or weak in the first place are broad and complicated — far more than an introduction like this can fully cover. They likely include the chronic, low-grade stress of modern life; sleep that is chronically insufficient or disrupted; digital environments and algorithms engineered to trigger constant dopamine-driven stimulation rather than rest and recovery; the erosion of the deep, physically-present community and co-regulation humans evolved to depend on; disruptions to early childhood development; and a growing body of research pointing to environmental exposures — including microplastics, heavy metals, endocrine-disrupting chemicals, PFAS, chronic noise, and electromagnetic fields — that may affect the brain’s physical capacity for connection and regulation.
My goal here is not to convince you these are settled facts. Much of this is genuinely emerging science, not consensus. I can’t even claim a direct causal chain has been proven. My goal is to present my hypothesis honestly, and to invite you to consider it — alongside the solution that follows from it - and decide for yourself whether it matters, and whether it might help, as I believe.
If the foundations of our neural wiring are under more pressure now than they once were, our approach to processing grief must account for this — rather than assuming everyone has the same neural capacity to “work through it” that earlier generations may have had. If the reasons grief is harder to move through are rooted in the state of our neural connections, then the solution must address that directly. I believe that developing, building, repairing, and strengthening these connections is not a nice-to-have alongside grief support — it is central to genuinely healing, integrating, and living alongside grief. Thankfully, research also shows that neuroplasticity — the brain’s ability to form new connections — means our capacity to process, integrate, and accommodate grief can be improved as we build, repair, and strengthen our neural connections, with the right kind of support, repeated over time.
I also believe that “finishing” grief, or “getting over it,” without addressing what’s happening at the level of neural connection, is incomplete. It can leave people stuck, or numb, or simply relieved that the pain has faded — without ever accessing what grief, processed well, can actually offer: deeper meaning, a changed relationship with love and loss, and real personal growth. I don’t think grief is only something to survive. I think, done well, it’s something that can leave you more whole than before — and I think that outcome depends on the health of the neural connections doing the work.
This is the founding hypothesis behind grief.game: that many people navigating pet loss grief may benefit from something more deliberate and more personalized than “give it time” — and that a well-designed Digital Therapeutic, grounded in both neuroscience and clinical grief expertise, can help rebuild that capacity directly, so that grief can do what it’s actually capable of doing.
