The Myth of Mental Illness: Mindset Optimization

It's fascinating how neuroplasticity — the brain's remarkable ability to adapt and reorganise — is something we've had to rediscover rather than accept as a default understanding of ourselves. Yet many people still believe that mental illness is a fixed condition, and even with all the evidence of adaptability that surrounds us, still struggle to believe in their capacity to change. Modern neuroscience challenges these outdated notions, as does the evidence from epigenetics, showing that humans have a far greater capacity for growth and adaptation than once thought.

This perspective echoes the argument made by Thomas Szasz that many conditions labelled "mental illness" (such as anxiety and depression) reflect difficulties in living and perception rather than strictly medical disease. Unlike most physical illnesses, the majority of disorders listed in the Diagnostic and Statistical Manual of Mental Disorders (DSM) cannot be traced to clear biological pathology in a specific part of the brain. While some neurological conditions involve observable damage or dysfunction, most psychiatric diagnoses do not.

These difficulties can be seen as a disconnection between current life and consciousness — how we should be living. The accumulated stress across the domains explored in the previous post creates the conditions in which psychological distress becomes increasingly likely.

Disruptions, Disturbances, and the Limits of Trauma

Today, these difficulties are often attributed to "trauma," typically linked to a lack of care during critical developmental periods or destabilising experiences later in life. However, an often overlooked factor is the absence of guidance. Development requires not only protection and affection but also structured input that teaches individuals how to perceive, interpret, and respond to the world. This absence of learning and development creates gaps that manifest as challenges later in life, compounding stress and limiting growth.

For this reason, I find the terms disruptions and disturbances more appropriate than "trauma" when describing setbacks. "Trauma" often implies a fixed state tied to a specific cause, leaving a lingering reminder or scar that many attach to their identity. "Disruptions and disturbances" better represents the issue. It reflects a disconnection in the system, caused by incorrect or incomplete inputs during development. These gaps lead to distortions in decision-making and behaviour. If they continue to build, the system can become corrupted, no longer functioning as it should. However, it can be restored through neuroplasticity — the brain's inherent ability to adapt and reorganise — though it may struggle to do so by itself.

Neuroplasticity

Neuroplasticity reflects the brain's dynamic and "live-wired" nature, a term coined by David Eagleman in his book Livewired: The Inside Story of the Ever-Changing Brain (2020). He uses this term to challenge the idea of the brain as a fixed electrical circuit, instead describing it as a constantly adapting system that rewires itself in response to experience. Unlike a hardwired machine, the brain is fluid and flexible, reorganising its connections based on inputs, outputs, and feedback. This understanding has profound implications for human potential, showing that our brains are not static but continuously evolving throughout life.

Neuroplasticity thrives when changes are personally relevant, as this relevance triggers the release of acetylcholine, which facilitates attention and learning. As progress is made toward the intended goal, dopamine is released, boosting motivation and reinforcing the learning process.

Relevance exists on a spectrum of pleasure and pain, and where an experience falls on this spectrum influences how much input is required for learning. For example, touching a hot stove provides immediate pain, so only one lesson is needed to avoid repeating it. On the other hand, less painful experiences might require more time and repetition to internalise.

Pleasurable experiences also require fewer inputs to learn because you're more invested. Learning an instrument progresses far faster when it carries personal meaning. If a grandparent lights up every time you play, that immediate joy and social feedback deepens motivation and reinforces the learning, driving you to repeat it. Pleasure doesn't always have to be immediate, either. It can also be tied to future rewards, which motivate effort and learning in the present.

There are, however, crucial developmental stages. Neglecting or missing them can make the brain's ability to adapt or learn significantly more difficult, if not nearly impossible. This fluidity of development tends to slow down around the age of 25, when the brain is often seen as more crystallised or fully developed.

But this isn't just about brain structure. It's also related to the fact that many individuals at this age, or those facing developmental challenges, have become fixed in routines: career, relationships, lifestyle choices, or having caretakers doing everything for them. They've developed a stable set of beliefs, values, and behaviours that have allowed them to navigate life and ensure survival. This stability reduces the need for novelty, which in turn diminishes motivation to develop new skills or make changes. Unless something disrupts their established life entirely, there is often little drive to pursue further development.

Brain Balance

This is further supported by the work of Robert Melillo, who introduced the concept of Functional Disconnection Syndrome (FDS) to explain various neurological and developmental disorders, including autism spectrum disorder, ADHD, dyslexia, and OCD. Rather than viewing these conditions as fixed diagnoses, FDS reframes them as problems of connectivity: failures of integration and communication between the two hemispheres during critical developmental periods. Much like the DSM conditions challenged earlier, these are not structural problems but disruptions in a developing system that, through targeted intervention and neuroplasticity, can be meaningfully addressed.

Mindset

Quite possibly the most overlooked element to all of this is mindset — the current state and health of our psyche, shaping how we perceive and interact with the world. Mindset sits on a spectrum between fixed and growth. The fixed mindset aligns with pessimism, seeing abilities and circumstances as static, while the growth mindset aligns with optimism, embracing adaptability and progress in line with what neuroplasticity tells us about the brain. Where we sit on that spectrum largely dictates our outcomes.

Optimism is often misunderstood as blind enthusiasm. In reality, it is an outcome. One that emerges naturally as stress decreases across the domains of life and perception moves closer to truth. It rarely arrives all at once. It develops through the process of facing and overcoming difficulty, gradually integrating those experiences into a clearer, more grounded understanding of the world.

Conclusion: Mindset Optimisation

The myth of mental illness often stems from outdated views that limit our understanding of human potential. Rather than viewing psychological difficulties as permanent or irreparable, we can understand them as disruptions and disturbances in a living, adaptive system, caused by misalignment, incomplete development, and distorted perception. These can be corrected through targeted intervention and an honest orientation toward growth.

A key component of this process is relevance. When we make our idealised self our aim, it sparks the brain's natural drive to learn and adapt, drawing in everything relevant to achieving it. In turn, this creates a positive feedback loop, driving continuous growth toward an optimised mindset.

An optimised mindset is achieved when we master our psyche. This means developing the internal connections and clarity that allow us to think effectively, regulate our emotions, and make decisions aligned with reality. This mastery expresses itself externally through how accurately we read and respond to the world, our relationships, and the domains of life. This is not a destination but a direction, and it begins with understanding the system that makes all of it possible.
