Diabetes Res Clin Pract. 2022 Apr:186:109808. doi: 10.1016/j.diabres.2022.109808. Epub 2022 Mar 2.

Abstract

Background: Type II Diabetes mellitus (T2DM) patients are at the risk of developing cerebrovascular diseases, often contributed by altered cerebral haemodynamics. We present a systematic review of studies on cerebral haemodynamics assessment using transcranial Doppler (TCD) in T2DM.

Review method: A systematic review of the published articles in the English language between 1991 to 2021.

Data sources: Articles were retrieved via Pubmed and Cochrane library. We included Cross-sectional, prospective, retrospective, randomized controlled, and cross-over studies for this review.

Results: A total of 25 articles met the inclusion criteria, which provided data for 3212 patients.

Conclusion: Cerebral autoregulation is often impaired among patients with T2DM. The risk increased with the duration of T2DM, related complications and presence of comorbidities.

Keywords: Cerebral haemodynamics; Cerebrovascular reactivity; Transcranial Doppler; Type II diabetes mellitus.
