The Relationship Between Controlling Risk Factors and Cerebral Haemodynamics in Lacunar Stroke

Understanding the Relationship Between Controlling Risk Factors and Cerebral Haemodynamic Changes in Lacunar Stroke, and Its Interaction With Ageing

Sponsor

University of Leicester

Enrollment

75 participants

Start Date

May 2, 2024

Study Type

OBSERVATIONAL

Conditions

Lacunar Stroke

Summary

The goal of this observational study is to look at differences in brain blood flow before and after management of risk factors such as high blood pressure and diabetes in patients with lacunar stroke. Participants will be asked to undergo a simple brain blood flow assessment at their initial appointment, whereby they will be asked to sit and stand twice. The patients will then be asked for a follow-up assessment 4 weeks after, identical to the first. This will allow us to look at any changes in brain blood flow from before management of risk factors and 4 weeks after management of risk factors.

Eligibility

Min Age: 18 Years

Inclusion Criteria3

Adults aged between 18-120 years.
Diagnosis of lacunar stroke syndrome.
New diagnosis or known diagnosis of hypertension and/or diabetes.

Exclusion Criteria2

Those who lack capacity can have a personal consultee consent to the study if they can still perform study requirements such as the sit-stand manoeuvre. Those who either cannot perform the manoeuvre or do not have a personal consultee to allow them to consent, are not able to take part.
Those with poorly controlled medical comorbidities affecting cerebral haemodynamics. (eg., heart failure).

Interventions

DEVICETranscranial Doppler Ultrasonography (TCD) during sit-stand manoeuvres

TCD will be used to measure the cerebral blood flow in the middle and posterior cerebral arteries. This will be done at rest and during two sit-stand manoeuvres, whereby the participant will be asked to stand (from a seated position) and stay standing for 1 minute. The participant will then be given time to recover before repeating the manoeuvre. This will occur at the first visit and the follow-up visit 4 weeks after.
