Familial Focal Epilepsy with Variable Foci

FFEVF


Presentation

  • Clinical Presentation In FPEVF, affected family members may present with different types of partial epilepsy, which are, however, invariable within each subject.[neupsykey.com]
  • Some patients can present an aura previous to the seizure or show automatisms (unconscious behaviors) during the seizures, which can take place both during wakefulness or at night. There is often secondary generalization of the seizures.[amplexa.com]
  • The present studies have not look at singletons, but they followed up their findings in other families with focal epilepsies.[epilepsygenetics.net]
  • Figure 3 is a phylogenic tree revealing a highly conserved DEPDC5 protein present in metazoa and fungi. EXAMPLES The present invention is further illustrated by the following examples.[google.sr]
Asymptomatic
  • Severity varies among family members; some may be intractable to medication but usually these are infrequent, easily controlled, or even asymptomatic, manifesting only with EEG foci. Differential diagnosis Symptomatic focal epilepsies.[epilepsy.com]
  • In some patients, it can also help guiding the treatment and predict the risk of being affected for asymptomatic relatives [5,6].[swisscheckup.com]
  • EEG abnormalities can be brought up by sleep and may be present in asymptomatic family members. The extent of EEG changes is not indicative of severity or prognosis of the epilepsy syndrome.[doctorstrizhak.com]
  • Seven asymptomatic obligate carriers (N-II:2, S-II:5, S-III:4, S-III:7, S-III:10, S-IV:5, O-II:8) and four asymptomatic at-risk individuals aged 8-42 (N-111:5, N-IV:7, S-IV:7, S-V:2) carried the mutations.[google.sr]

Suggestibility
  • Two different loci have been associated with FPEVF, the first with suggestive linkage on chr 2q, 28 and the second on chr 22q. 36 However, the gene(s) have not been cloned.[neupsykey.com]
  • The first suggestive linkage was on chromosome 2q ( Scheffer et al 1998 ), but posterior reanalysis excluded such finding ( Klein et al 2012 ). Indeed, no other tested families showed linkage to chromosome 2q ( Morales-Corraliza et al 2010 ).[medlink.com]
  • Shared homology with G protein signaling molecules and localization in human neurons suggest a role of DEPDC5 in neuronal signal transduction.[ncbi.nlm.nih.gov]
  • Both studies find a high frequency of DEPDC5 mutation in families with focal epilepsies, suggesting that they have identified a major gene rather than a rare mutation found in an individual family.[epilepsygenetics.net]

Aura
  • Some patients can present an aura previous to the seizure or show automatisms (unconscious behaviors) during the seizures, which can take place both during wakefulness or at night. There is often secondary generalization of the seizures.[amplexa.com]
  • Frontal lobe seizures are the most frequent manifestation, but they have a different pattern in FPEVF as compared to that observed in ADNFLE ( Table 1 ): The seizures are less frequent, clusters and auras are rare, and daytime seizures as well as secondarily[neupsykey.com]
  • Many patients have an aura and show automatisms during the seizures, whereas others may have nocturnal seizures. There is often secondary generalization.[genecards.org]
  • […] localization-related epilepsies Mesial temporal sclerosis Pathologic changes in the mesial temporal region Common cause of refractory temporal lobe seizures in adults Controversial if link with prolonged febrile seizures early in life Seizure-types: Rising epigastric aura[emilytam.com]
Behavior Problem
  • However, some people with FFEVF have developed psychiatric disorders (such as schizophrenia ), behavioral problems, or intellectual disability. It is unclear whether these additional features are directly related to epilepsy in these individuals.[ghr.nlm.nih.gov]
