Brief Summary

Current management of hypertension in PD motor fluctuators is flawed. The current practice often is to treat transient hypertensive spikes reported by patients or measured in clinics with anti-hypertensive medications. This may contribute to morbidity by worsening orthostatic hypotension and increasing fall risk. There is a scarcity of literature on this subject and there is no documentation of severe hypertension with rises in systolic blood pressure exceeding 50% of baseline occurring during motor "OFF". There are two studies that have demonstrated that blood pressure fluctuation can occur in motor fluctuators during the "OFF" state1,2. The study by Baratti et al measured blood pressure in 13 Parkinson's disease patients, 7 with motor fluctuations and 6 without fluctuations. In the fluctuators, the mean systolic/diastolic blood pressures were significantly higher than the non-fluctuators during the "OFF" state but not the "ON" state.

Outcome Measures

Primary Outcomes (1)

  • Systolic Blood Pressure Change

    Blood pressure measurement taken at lowest "OFF" rating on the Unified Parkinson's Disease Rating Scale (UPDRS) and highest "ON" rating on the UPDRS.

    Change in systolic blood pressure from 08:30 am measurement to 11:00 am measurement.

Secondary Outcomes (1)

  • Diastolic Blood Pressure Change

    Change in systolic blood pressure from 08:30 am measurement to 11:00 am measurement.

Study Arms (1)

Fluctuator

Parkinson's subjects with rises in systolic blood pressure exceeding 50% of baseline during motor off periods to select for subjects with severe blood pressure fluctuations.

Other: No Intervention

Eligibility Criteria

Age18 Years - 99 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Parkinson's disease participants with motor fluctuations.

You may qualify if:

  • Idiopathic Parkinson's disease fulfilling UK Brain Bank clinical criteria.
  • Treatment with chronic levodopa (levodopa treatment for ≥ 3 years).
  • Rise in "OFF" systolic blood pressure exceeding 50% of baseline "ON" systolic blood pressure as shown by at home monitoring.
  • History of "wearing off" prior to 4 hours after the previous levodopa dose per patient report or chart documentation.

You may not qualify if:

  • Daily beta-blocker therapy.
  • Diabetes mellitus, autonomic neuropathy, or other condition known to alter autonomic functions.
  • Significant cognitive impairment as measured by the Montreal Cognitive Assessment score of \< 16
