219 Possible Causes for 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 tremor is a form of rhythmic myoclonus, presenting as postural or action tremor in some patients with progressive myoclonus epilepsy (PME), 76, 77 in Angelman syndrome[clinicalgate.com]

  • Lafora Disease

    Mutations of this gene cause a progressive myoclonus epilepsy called action myoclonus–renal failure characterized by adult and rarely late-teenage onset progressive tremor[doi.org] The first EEG record, carried out the day after admission, showed slightly slow background activity with bursts of slow waves and paroxysms of spikes and waves.[jnnp.bmj.com]

  • Idiopathic Generalized Epilepsy

    Generalized spike-wave discharges and diffuse paroxysmal fast activity were categorized as interictal and ictal, based on duration of less than 10 seconds or greater, respectively[ncbi.nlm.nih.gov]

  • Generalized Clonic or Tonic-Clonic Seizures

    ‘Contrary to popular folk belief, nothing should be placed in the mouth during the seizure. Severe injury could occur.’ Generalized tonic clonic seizures (grand mal seizures) are the most common and best known type of generalized seizure. They begin with stiffening of the limbs (the tonic phase), followed by jerking[…][epilepsynw.org]

  • Juvenile Myoclonic Epilepsy

    Juvenile myoclonic epilepsy (JME) is a type of epilepsy that starts in in childhood or the teen years. People who have it wake up from sleep with quick, jerking movements of their arms and legs. These are called myoclonic jerks. Even if you don’t have epilepsy, you’ve probably had these jerks that jolt you awake,[…][webmd.com]
