Table 1.
Age distribution and total number of cases separated for gender and type of dementia. Data is grouped by diagnosed autonomic dysfunction according to the Ewing batter protocol. Descriptive Data is denoted as mean±standard deviation (Median) and sample size n (Ewing battery). Ewing battery results are displayed for: Coefficient of variance (CV), Expiration-Inspiration ratio (EI), Valsalva phase IIb/IV ratio (VAL), and the TILT30/15 ratio for HUT. Descriptive analysis parameters for LFnu are calculated as percentage of total autonomic activity. The normalized LF activity (LFnu) is significantly increased by δ= +6.53% from supine resting to HUT
