Cerebro-Haemodynamic Changes in Type 2 Diabetes Mellitus Following Yoga Intervention: A Pilot Study

Area of Science:

• Neurology
• Endocrinology
• Integrative Medicine

Background:

• Type 2 Diabetes Mellitus (T2DM) significantly impairs cerebral hemodynamics, reducing blood flow and increasing vascular resistance.
• The progression of T2DM negatively impacts cerebrovascular function over time.

Purpose of the Study:

• To investigate the impact of an integrated yoga therapy approach on cerebral hemodynamics in individuals with T2DM.
• To assess changes in key cerebral blood flow parameters following a yoga intervention.

Main Methods:

• A randomized controlled trial involving 20 T2DM patients divided into yoga and control groups.
• The yoga group received 14 days of diabetes-specific yoga alongside standard medication.
• Cerebral hemodynamics were measured using Transcranial Doppler, assessing middle cerebral artery velocities and resistance indices.

Main Results:

• While not statistically significant, the yoga group exhibited an increasing trend in mean blood flow velocity (P = .07) and a decrease in resistance index (P = .89).
• No significant within- or between-subjects effects on cerebral hemodynamic parameters were observed after 14 days of yoga intervention.

Conclusions:

• Yoga intervention shows a potential, albeit non-significant, positive influence on cerebral hemodynamics in T2DM patients.
• These findings suggest further investigation into yoga's therapeutic role in vascular and metabolic disorders is warranted, possibly with larger cohorts and longer interventions.
