Clinical Observation for the Therapeutic Effect of mNGF on Cognitive Decline in Cerebral Small Vessel Disease

This study was a multicenter, prospective, randomized controlled trial. In this study, 510 patients with cognitive impairment of cerebral small vessel disease who met the inclusion criteria are randomly included in multiple centers and randomized into two groups (standard treatment group and mouse nerve growth factor addition treatment group). The standard treatment group is treated with conventional drugs and cholinesterase inhibitors. In addition to the above treatment, the mouse nerve growth factor addition treatment group is administered with nerve growth factor 20 μg (9000 U)/vial for 14 consecutive days, intramuscularly once a day. Systematic clinical evaluation of patient cognitive function is performed at baseline, 14-day, and 3-month follow-up, and imaging (MR) is also evaluated twice at baseline, 14-day, and 3-month follow-up. At last observe the clinical effect of mouse nerve growth factor on cognitive impairment of cerebral small vessel disease.
