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.
