Somatisia

Somatisia is a hypothetical medical concept used in speculative medicine and philosophy of mind to describe persistent somatic symptoms that arise from the brain’s interpretation of bodily signals rather than identifiable organ pathology. The term is not part of formal medical taxonomies and is mainly discussed in theoretical discourse and some science fiction narratives.

The name combines soma, meaning body, and -sia to emphasize interoception—the brain’s perception of internal bodily states. In discussions of Somatisia, researchers explore how attention, expectation, stress, and prior experiences shape symptom perception.

In this framework, individuals may report chronic pain, fatigue, dizziness, palpitations, sleep disturbance, and sensory sensitivities. Symptoms are often fluctuating and can be disabling, yet objective examinations fail to reveal consistent structural disease.

Somatisia is not a clinical diagnosis in standard medicine. It appears in theoretical and literary contexts and is treated conceptually alongside functional somatic syndromes and somatic symptom disorders, with emphasis on validating patient experiences while pursuing appropriate medical evaluation.

Proposed mechanisms include altered interoceptive processing, central sensitization, and dysregulated autonomic or neuroimmune signaling, modulated by psychological factors such as anxiety, mood, and coping strategies.

When used as a model, management favors multidisciplinary care, patient education, and approaches like cognitive-behavioral therapy, graded activity, sleep hygiene, mindfulness, and stress reduction, tailored to individual symptom profiles.

Somatisia has appeared mainly in speculative literature and theoretical discussions about mind–body connections, offering a framework for examining how perception and physiology interact in health and illness.
