Bruxism: its significance in coma.

R Pratap-Chand, M Gourie-Devi

    Clinical Neurology and Neurosurgery
    |January 1, 1985
    PubMed
    Summary

    Bruxism, or teeth grinding, was studied in 20 coma patients. This non-functional grinding appeared at various consciousness levels but resolved with significant improvement, correlating with sleep-wake cycles.

    Area of Science:

    • Neurology
    • Sleep Medicine
    • Dental Sleep Medicine

    Background:

    • Bruxism, characterized by non-functional teeth grinding, has multifactorial etiologies.
    • Understanding bruxism in altered states of consciousness is crucial for neurological assessment.

    Purpose of the Study:

    • To investigate the correlation between bruxism and consciousness levels in coma patients.
    • To explore the relationship between bruxism, neurological signs, and sleep-wake cycles.

    Main Methods:

    • Observational study of 20 coma patients exhibiting bruxism.
    • Assessment of consciousness level, eye movements, respiration, cold caloric tests, and motor deficits.
    • Monitoring for the presence and timing of sleep-wake cycles.

    Main Results:

    • Bruxism manifested across diverse levels of consciousness in coma patients.
    • The disappearance of bruxism was associated with significant improvements in consciousness.
    • A correlation was observed between the emergence of bruxism and the onset of sleep-wake cycles.

    Conclusions:

    • Bruxism in coma patients is linked to consciousness state and recovery.
    • The presence of sleep-wake cycles may influence bruxism in severe neurological conditions.
    • Further research is warranted to elucidate the precise mechanisms linking bruxism to consciousness and sleep disturbances.
