Calcium: pacesetting the periodic psychoses.

J S Carman, R J Wyatt

    The American Journal of Psychiatry
    |August 1, 1979
    PubMed
    Summary
    This summary is machine-generated.

    Dihydrotachysterol (DHT) worsened psychosis and agitation in patients by increasing serum calcium and phosphorus. Synthetic salmon calcitonin (SCT) reduced agitation, suggesting a link between calcium levels and psychosis symptoms.

    Area of Science:

    • Neuropsychopharmacology
    • Endocrinology
    • Psychiatry

    Background:

    • Psychotic disorders are often associated with behavioral disturbances.
    • Calcium and phosphorus levels are critical for neurological function.
    • The role of mineral metabolism in psychosis requires further investigation.

    Purpose of the Study:

    • To investigate the effects of dihydrotachysterol (DHT) on psychotic patients.
    • To explore the potential therapeutic role of synthetic salmon calcitonin (SCT) in managing psychosis-related agitation.
    • To examine the relationship between serum/CSF calcium and phosphorus levels and psychotic symptoms.

    Main Methods:

    • A double-blind study involving eight psychotic patients.
    • Oral administration of dihydrotachysterol (DHT) and synthetic salmon calcitonin (SCT).

  • Monitoring of serum calcium, phosphorus, and creatine phosphokinase (CPK) levels, alongside behavioral assessments and cerebrospinal fluid (CSF) calcium measurements.

    • Main Results:

    • DHT administration led to increased psychosis, agitation, serum calcium, and phosphorus within two weeks.
    • Serum creatine phosphokinase (CPK) levels rose in most patients receiving DHT.
    • SCT treatment decreased agitation frequency and severity, with a concurrent increase in CSF calcium.

    Conclusions:

    • Elevated serum calcium and phosphorus induced by DHT may correlate with increased agitation and psychosis.
    • CSF calcium shifts might be inversely related to serum mineral changes during acute psychosis.
    • Findings suggest a potential mechanism linking mineral dysregulation to behavioral and neurological changes in psychosis.
