From: Rubidium and potassium levels are altered in Alzheimer’s disease brain and blood but not in cerebrospinal fluid

K levels were significantly increased in AD serum (a; one-way ANOVA; * p < 0.05), whilst Rb levels were conversely decreased in AD (b; * p < 0.05); the latter mirroring our observation in brain homogenates. The ratio of Rb to K was significantly (*** p < 0.001) decreased in AD (c), though Rb and K levels were less well correlated in serum (d). In a subset (n = 30 per group) of erythrocytes from HC and AD groups, there was no significance difference in metal concentration (e, f). Boxes depict 25th and 75th percentiles and mean; error bars represent minimum to maximum values
