Table 2 Effect of acute sleep deprivation on CSD electrical threshold

From: Acute sleep deprivation enhances susceptibility to the migraine substrate cortical spreading depolarization

Group n CSD Threshold (μC)
mean (range) average ± SD
Control 19 50 (1–800) 108 ± 227
6 h sleep deprivation 11 20 (1–400)   63 ± 116
12 h sleep deprivation 14 10 (1–300)*   41 ± 76*
6 h and 12 h sleep deprivation 25 15 (1–400)*   50 ± 93*
  1. Sleep deprivation of 12 h but not 6 h decreased the electrical CSD threshold. All controls (6 h controls and 12 h controls) were pooled for statistical analysis, as no significant difference was found between the two control groups
  2. *p < 0.01 vs. control
