217 Possible Causes for Jerk-Locked Premyoclonus Spikes, Paroxysmal Activity - Spikes, Progressive Action Tremor

  • Benign Adult Familial Myoclonic Epilepsy

    Usually, myoclonic tremor is the presenting symptom, characterized by tremulous finger movements and myoclonic jerks of the limbs increased by action and posture.[uniprot.org] This was referred to as posterior paroxysmal activity by Holmes et al.[euroformhealthcare.biz] […] cortical spikes detected by the jerk-locked back-averaging) ( Ikeda et al., 1990 ).[academic.oup.com]
