    Patients with schizophrenia experience pain from both physical and psychological origins, with common sites including the head, leg, and back. Further research is needed to understand the influence of phenothiazines on pain perception in this population.

    Area of Science:

    • Psychiatry
    • Pain Medicine
    • Clinical Psychology

    Background:

    • Schizophrenia is a complex mental disorder often associated with altered sensory processing.
    • Pain perception and its relationship to psychological factors in schizophrenia require further elucidation.
    • Previous studies suggest potential differences in pain experience between schizophrenia and other psychiatric conditions like anxiety or depression.

    Purpose of the Study:

    • To investigate the phenomenology of pain in patients diagnosed with schizophrenia.
    • To differentiate between physical and psychological origins of pain complaints in this cohort.
    • To describe the characteristics and common sites of pain experienced by individuals with schizophrenia.

    Main Methods:

    • A cohort of 78 patients with schizophrenia was examined.

  • Patients reporting current pain complaints were identified and further assessed.
  • Pain origins were categorized as physical or psychological based on clinical evaluation.

    • Main Results:

    • Twenty-nine out of 78 patients reported current pain.
    • Of those with pain, 13 had identifiable physical causes, while 16 had pain of seemingly psychological origin.
    • The most common pain sites were the head, leg, and back, often described in sensory terms.

    Conclusions:

    • Patients with schizophrenia experience pain from both physical and psychological causes.
    • Pain related to delusions or hallucinations was rare in this sample.
    • The influence of phenothiazine medication on pain experience in schizophrenia remains uncertain.
