Presentation
Usually, myoclonic tremor is the presenting symptom, characterized by tremulous finger movements and myoclonic jerks of the limbs increased by action and posture. In a minority of patients, seizures are the presenting symptom. [uniprot.org]
Jerk-locked back-averaging confirms CT; typical giants SEPs and enhanced C-reflex are presents. Molecular-genetic analysis excluded a linkage to chromosome 8q24 and suggests a linkage to chromosome 2p11.1-q12.2. [moh-it.pure.elsevier.com]
Clinical description BAFME usually presents in the second decade of life (but age of onset can range from age 11-50) with a minor cortical hand tremor. [orpha.net]

- Shivering
Abstract Benign adult familial myoclonic epilepsy (BAFME or FAME) is an autosomal dominant condition, characterized by shivering-like tremors of cortical origin, myoclonus, and epilepsy. [ncbi.nlm.nih.gov]
Historical note and terminology The term “cortical tremor” was introduced by Ikeda and colleagues to indicate a postural and action-induced shivering movement of the hands mimicking essential tremor but showing the electrophysiological findings of cortical [medlink.com]

Therefore, one wonders whether these drugs may have played a role in causing the action and postural, shivering-like twitching movements of the patients that also appeared later than epileptic seizures, differently from most patients with FCMTE ( Striano [academic.oup.com]

EEG
- Photoparoxysmal Response
Photoparoxysmal responses (PPR) were noted in 18 (95%) patients with BAFME but 1 (10%) with EGTCS. CONCLUSION: Faster frequency of GSW, compared with that in EGTCS, accompanied by PPR may be characteristic EEG features of BAFME. [ncbi.nlm.nih.gov]
Generalized paroxysmal abnormalities were found in all cases, whereas a photoparoxysmal response was observed in two. JLA showed a positive–negative spike or a series of wavelets related to myoclonus on the contralateral sensorimotor regions. [onlinelibrary.wiley.com]

- Generalized Polyspikes
Bursts of generalized polyspikes and waves (multiple spike-and-slow-wave complexes) may also be seen, [30] especially during sleep and in syndromes with older age of onset. [reference.medscape.com]
The EEG shows generalized polyspike and spike-and-wave discharges, frequently precipitated by photic stimulation. [clinicalgate.com]
Generalized polyspike wave discharges (in 1 of 36 [3%]) or irregular, generalized, frontally maximal sharp wave discharges (in 1 of 36 [3%]) were seen. [jamanetwork.com]
The EEG may be normal at the time of the initial febrile seizures, but when the myoclonus starts, generalized spike-and-wave or polyspike-and-wave discharges occur. [euroformhealthcare.biz]

In the cryptogenic or symptomatic generalized epilepsies, absence seizures are often associated with slow spike-wave complexes of 1.5-2.5 Hz [5] ; these are also called sharp-and-slow-wave complexes. [reference.medscape.com]

AEDs are used to prevent recurrent seizures. [stlukes-stl.com]
Keep stairs blocked off as much as possible to prevent children from falling down. Children with controlled epilepsy may still ride a bicycle, however they should wear protective gear at all times and never bike alone. [know-the-ada.com]
Successful treatment with adrenocorticotropic hormone (ACTH) or vigabatrin can prevent further developmental regression. Many children develop other seizure types and go on to have Lennox-Gastaut syndrome (see information below). Dravet syndrome. [epilepsyfoundationmn.org]
