Tremor and senile parkinsonism

R A Griffiths, J A Dalziel, K G Sinclair

    Journal of Gerontology
    |March 1, 1981
    PubMed
    Summary

    Subclinical tremor in elderly patients with dementia and mild Senile Parkinsonism can be distinguished from Parkinson's Disease using amplified recordings. This tremor recording aids in diagnosing Parkinsonism and monitoring treatment effectiveness.

    Area of Science:

    • Neurology
    • Geriatrics
    • Biomedical Engineering

    Background:

    • Senile Parkinsonism and dementia are common in the elderly.
    • Distinguishing between Parkinson's Disease and other tremor disorders is clinically important.
    • Subclinical tremor may be present in neurological conditions.

    Purpose of the Study:

    • To investigate the characteristics of subclinical tremor in elderly patients with mild Senile Parkinsonism and dementia.
    • To determine if amplified tremor recordings can differentiate this tremor from Parkinson's Disease and Senile Tremor.
    • To assess the diagnostic and therapeutic monitoring value of tremor recording.

    Main Methods:

    • A study involving 100 Day Hospital patients.
    • Analysis of tremor frequency in 26 elderly patients with mild Senile Parkinsonism and dementia.
    • Utilizing amplified recordings for tremor analysis.
    • Reviewing patient history for cerebro-vascular disease.

    Main Results:

    • Subclinical tremor in the studied group occurred with a frequency similar to Parkinson's Disease.
    • Amplified recordings distinguished this tremor from both Parkinson's Disease and Senile Tremor.
    • Half of the patients had a significant history of cerebro-vascular disease.

    Conclusions:

    • Amplified tremor recording is valuable for diagnosing Parkinsonism.
    • Tremor recording can assist in assessing the response to Parkinsonism treatments.
    • Cerebro-vascular disease may be a contributing factor in some cases.
