Brief Summary:
A Randomized Pivotal Study of RenewTM NCP-5 for the Treatment of Mild Cognitive Impairment due to Alzheimer's Disease or Mild Dementia of the Alzheimer's Type is a pivotal, single blind, parallel design, multi-site study intends to examine the efficacy and safety of RenewTM NCP-5 therapy in the treatment of Cognitive Impairment due to Alzheimer's Disease or Mild Dementia of the Alzheimer's Type. Subjects will be prospectively randomized to treatment or sham (in a 1:1 ratio) using stratification for Cognitive Impairment due to Alzheimer's Disease or Mild Dementia of the Alzheimer's Type, and Cardiovascular Risk (CVR) score at multiple sites. Subjects, ages 55-85, will be consented for 13 months and will receive thirty-five 60-minute RenewTM NCP-5 treatment sessions during a 7-to-12-week initial treatment period, and then transition to a lower frequency maintenance period (twice a week) for a total treatment period of 24 weeks.

Arm Intervention/treatment
Experimental: Treatment Arm
The first four sessions will be the escalation phase using the Renew NCP-5. There will be a 5-minute ramp up period where the pressure is increased 1 psi/min until the desired pressure is reached. The goal for the treatment group will be at least 2.5 psi for the first treatment, and then escalate the pressure gradually through the fourth session with an average goal of 3 psi/session. After the fourth session, the pressure will be slowly increased to reach the maximum level the subject can tolerate with a goal of reaching 3-6 psi.
Device: Renew NCP-5
Treatment will be given 3-5 times a week for a total of 35 treatments over 12 weeks.

Sham Comparator: Sham Arm
The subjects will receive the same initial and maintenance treatment regimen on the Renew NCP-5. The pressure will not exceed an average of 0.5 psi over all treatments.
Device: Renew NCP-5
Treatment will be given 3-5 times a week for a total of 35 treatments over 12 weeks.

Primary Outcome Measures :
  1. Mean Change From Baseline to 24 Weeks in Vascular Dementia Assessment Scale Cognitive Subscale (vADAS-cog) Using the Average of Scores at 12, 18 and 24 Weeks. [ Time Frame: 24 weeks ]
    The vADAS-cog assessment includes 17 subscale scores. The total score is the sum of all scaled scored from 0-120. The higher values represent more cognitive impairment. The change in vADAS-cog scores from baseline at the timepoints of 12, 18, and 24 weeks is averaged together for each patient. The primary outcome measure is the average of those values for all patients in a group.

Secondary Outcome Measures :
  1. Number of Participants With Treatment Related Adverse Events as Assessed by MedDRA. [ Time Frame: 24 weeks ]
  2. Number of Participants With Treatment Related Serious Adverse Events as Assessed by MedDRA. [ Time Frame: 24 weeks ]
