Benign adult familial myoclonus epilepsy is a progressive disorder: no longer idiopathic generalized epilepsy Volume 18, issue 1, March 2016

Figure 1

Histogram of the frequency of the posterior dominant rhythm (PDR) in 19 benign adult familial myoclonus epilepsy (BAFME) patients and 38 age-matched control subjects. There was a clear difference between the distribution of PDR frequency in BAFME patients and age-matched control subjects. The PDR frequency was slower in BAFME patients than in age-matched control subjects.

Figure 2

Linear regression between age at the time of EEG recording and frequency of PDR in 19 BAFME patients and 38 age-matched control subjects. A simple regression curve for BAFME patients is represented by the black line, and for age-matched control subjects by the grey dotted line. Open circles indicate BAFME patients and crosses indicate age-matched control subjects. There was a non-significant tendency for a slowing of PDR with age in both BAFME and age-matched control subjects. Comparison of the gradients corresponding to PDR frequency relative to age between the two groups revealed no significant difference. Definitions of PDR and BAFME are shown in the legend for figure 1.
