Not Applicable

Active, not recruiting

• Conditions: Diabetic Peripheral Neuropathy

• Registration Number: NCT06048653
• Lead Sponsor: heba ahmed khalifa

Brief Summary

Diabetic peripheral neuropathy (DPN) occurs due to long standing hyperglycemia and associated metabolic derangements. Cognitive impairment is a common complication in diabetes mellitus. It is associated with a faster rate of cognitive decline.

Detailed Description

This research aims to

* determine the effect of non-invasive Vagus nerve stimulation on cognitive functions in diabetic peripheral neuropathy.

* investigate the correlation between cognitive function and severity of diabetic neuropathy.

* investigate the correlation between cognitive function and quality of life in diabetic peripheral neuropathy.
