DPDR as a perceptual state and mechanisms of its persistence

DPDR (depersonalization / derealization) remains one of the most difficult states to differentiate at the intersection of psychology, psychiatry, and neurophysiology. In clinical practice, it is often treated as secondary, diffuse, or embedded within more familiar diagnostic frameworks — anxiety-related, autonomic, functional, or psychosomatic.

This section does not propose an alternative diagnosis and does not challenge existing classification systems. Its purpose is to expand the field of differentiation, viewing DPDR not only as a set of symptoms but as a process that can persist through specific maintaining mechanisms.

The approach presented here is based on several observations:

• DPDR often emerges as an adaptive response to nervous system overload rather than as an independent disorder.

• After the acute phase has resolved, the state may persist not due to ongoing pathology, but because of secondary maintaining processes.

• These processes involve not only anxiety or autonomic regulation, but also patterns of attention, interpretation, language, and associative memory.

Within this section, DPDR is examined as a condition in which a perceptual knot may form — a stable configuration sustained by the interaction of several functional elements. This perspective does not replace diagnosis, but helps explain why the state may become prolonged in some individuals and why direct symptom-focused interventions are not always sufficient.

The materials are intended for physicians, psychologists, and other professionals working with anxiety, overload, and altered perception. They may serve as:

• an additional lens for differential understanding;

• a way to reduce the risk of secondary fixation;

• a foundation for more careful work with attention and explanatory language.

Each article addresses a specific aspect of the process — from diagnostic frameworks to fixation mechanisms and associative clusters. The texts may be read sequentially or selectively, depending on professional interest.
