    Fire up your espresso machine.

    In this most recent study published in the journal Parkinsonism and Related Disorders, 79 newly diagnosed PD patients received follow up for 4 years.

    Highlights
    •Caffeine consumption was associated with a reduced accrual of PD motor disability.
    •PD patients with higher caffeine use presented a reduced need for l-Dopa treatment.
    •Non-motor symptoms presented a milder progression among PD patients using caffeine.

    …considering the whole study period, each additional espresso cup per day (50 mg of caffeine) was more likely associated with 5-point lower UPDRS part III total score, and with 5-point lower NMSQuest total score, but not with UPDRS part IV total score.

    UPDRS refers to the Unified Parkinson’s Disease Rating Scale, which is how doctors assess the severity of a patient’s PD. Lower is better. Part III is the clinician-scored and monitored motor evaluation. Part IV, which showed no difference in this study, is about complications of treatment such as dyskinesia and on/off fluctuations. The rating scale is defined at http://www.movementdisorders.org/MDS-Files1/PDFs/Rating-Scales/MDS-UPDRSfinal_Update.pdf

    NMSQuest refers to the Nonmotor Symptoms Questionnaire for Parkinson’s Disease, which attempts to provide a comprehensive assessment of the range of nonmotor symptoms in PD. The rating scale is defined at http://www.movementdisorders.org/MDS-Files1/PDFs/MDS-UPDRS-Rating-Scales/NMSQ.pdf
