Habit as a Recurrent Functional System

A habit is not just a repeated act. It is a recurrent functional system : a pattern of organization that forms around a result, is stabilized through repetition and feedback, and can continue to operate over time in different degrees of strength, flexibility, and rigidity. This means that a habit has a structure, not only a content. What matters is not only what a person does, but how the whole cycle is arranged: what the habit is trying to achieve, what situation activates it, what action is taken, and what kind of learning follows from the outcome. In that sense, the habit is a system that keeps rebuilding itself. Some habits remain temporary. They appear in response to a specific need or task and then fade when the situation changes. Others become recurrent but still flexible, returning in similar contexts while remaining open to adjustment. Some develop into long‑term structures that support adaptation, competence, and daily functioning. Others become chronified , continuing to or...

Seven workplace solvents linked to Parkinson’s disease

Image
Recent findings presented at the International Congress of Parkinson’s Disease and Movement Disorders highlight occupational solvents as critical, yet underrecognized, environmental contributors to neurodegeneration. While the link between certain industrial degreasers and Parkinson’s disease has been recognized in isolated contexts, an analysis of over 31,000 individuals in the Parkinson’s Progression Markers Initiative dataset demonstrates that the threat extends across multiple everyday commercial compounds. Where exposure occurs The chemicals identified in the study span heavy manufacturing, automotive maintenance, aerospace facilities, printing operations, and everyday commercial workshops: Trichloroethylene (TCE): Commonly encountered in precision metal degreasing, circuit board cleaning, paint stripping, and historic dry cleaning operations. Kerosene and jet fuel : Fuel handling, aviation maintenance, mechanical engine flushing, and combustion-based industrial heating. Carbo...

Beyond the mirror: why reducing psoriasis to body image misses the pathology

Image
The reductionist trap of cosmetic framing The recent report in Medscape on the Mexican cohort study makes a valid attempt to look beyond skin plaques, yet it stumbles into a classic reductionist trap. By framing the problem around "body image," "self-esteem," and "aesthetic distress," the authors inadvertently reduce a severe, chronic systemic pathology to a cosmetic and psychological inconvenience. While patient distress is undeniable, treating psoriatic manifestations as superficial flaws that induce emotional dissatisfaction fundamentally misdiagnoses the true nature of the illness. The clinical reality is not that patients are merely unhappy with how their skin looks in a mirror. The reality is that the organism is dealing with widespread immuno-inflammatory dysregulation that alters tissue architecture, central nervous function, and systemic integrity. he skin plaque as a peripheral marker of systemic autoimmune inflammation Dermatological scoring i...

Acute low back pain: did the new guidelines overlook a simple treatment option?

Image
Low back pain is among the most common reasons people seek medical care. Most acute episodes improve without invasive intervention, but pain can substantially restrict movement, disrupt sleep, and interfere with everyday activities. Effective early treatment should therefore accomplish two distinct goals: reduce suffering and preserve mobility without imposing unnecessary biological risks. A multidisciplinary clinical practice guideline from the American Academy of Pain Medicine , published in Pain Medicine in 2026, reinforces conservative care principles. It recommends patient education, continued low-impact movement, superficial heat, and oral nonsteroidal anti-inflammatory drugs , while discouraging prolonged bed rest, unnecessary imaging, and routine opioid prescribing. Yet an important therapeutic option receives little attention in the clinical recommendations: topical analgesics , including nonsteroidal anti-inflammatory drug formulations, capsaicin preparations , and other lo...

Functional systems of consciousness: the Basic Language of Living Results

From Reflex to Functional System The classical picture from which the physiology of behavior began looked very simple: there is a stimulus, a reflex arc, and a response. The world "presses" on the organism, and the organism reacts. This scheme works reasonably well when we talk about simple, stereotyped reactions, but it explains poorly most real actions of a living being. A human being does not simply react to what is happening now. A person anticipates, chooses among several options, takes into account experience, memory, motivation, consequences, risks, and the social context. The same is true for an animal: it does not just "jump at a sound"; it evaluates whether this is prey, a predator, or something indifferent and neutral. The linear formula "stimulus → reflex → response" turned out to be too simple to describe this complexity. P.K. Anokhin proposed a different view. At the center he placed neither the stimulus nor an isolated reflex arc, but the...

The risk of naming: why psychiatric labels fail without a map of time and habitat

Image
When a diagnostic name becomes an identity, it ceases to be a flexible clinical hypothesis and begins to dictate how a person lives, how institutions respond, and how society interprets human suffering . In his Medscape commentary , Dr. Temitope Ogundare raises a fundamental warning for contemporary medicine: the relentless expansion of diagnostic vocabulary risks medicalizing the human condition itself . Sadness is swiftly recoded as major depressive disorder , distractibility as attention-deficit/hyperactivity disorder , social awkwardness as autism , and painful life ruptures as trauma . His call for diagnostic humility rests on a simple truth: distress is not necessarily disorder, statistical or temperamental difference is not disease, and moral failure, bad judgment, or systemic friction should not be reflexively pathologized . This critique is both necessary and timely. Yet from the perspective of our work on stress systems across time —developed in Stress Systems Across Tim...
