Long-term outcomes in temporal lobe epilepsy with glutamate decarboxylase antibodies
ConclusionMost patients with temporal lobe epilepsy and CSF GAD65-Abs develop a chronic disease with progressive cognitive impairment and refractory epilepsy regardless of the presence of additional limbic symptoms at onset.
CONCLUSIONS: Although no single clinical feature definitively distinguishes PNES from ES, several features may be suggestive of a PNES diagnosis, including longer duration, negative emotion (i.e., fear) throughout the events, preseizure anxiety, ictal dissociation, and postseizure weeping. Fewer reports of ictal self-injury and postseizure amnesia and aches may also indicate the possibility of PNES. PMID: 32388401 [PubMed - as supplied by publisher]
Conclusions: This study indicates that SREDA is difficult to associate with any specific condition. The pathophysiology of SREDA can not be explained by a single mechanism. Even if it is mostly observed in older adults, it is also observed in young adults in this study. It is important to differentiate SREDA from ictal discharge to prevent misdiagnosis of epilepsy especially in nonepileptic paroxysmal events.
Discussion Memory is an important part of what distinguishes higher order species from others. Memory also is part of one’s self-identity. Difficulties in short-term memory can make common, everyday tasks difficult for the person experiencing the problem particularly if it recently occurred and the person’s long-term memory is intact. Difficulties with long-term memory can also have problems when language, events or even one’s own identity are affected. For some people the memory loss is temporary but for others, memory impairments are permanent and must be accepted and accommodated as part of the overall...
Aetiology of transient global amnesia (TGA) remains uncertain, though many have been proposed, including ischaemic, migrainous or epileptic pathologies.
Conclusion: Post-herpetic anti-NMDAr AIE could arise several months after infection. Clinicians must be aware of this possibility, particularly if cognitive and/or psychiatric symptoms occurred after a remitting period. In our two cases, only rituximab was associated with clinical improvement.
Prolonged epileptic seizures are the cause of neuronal death and brain damage. Lesions in different regions of the brain can lead to memory loss and cognitive disorders. It is therefore essential to seek out new neuroprotective drugs. Our aim was to investigate the therapeutic effects of oleuropein to improve seizure, oxidative stress and cognitive disorder in pentylenetetrazole (PTZ) kindling mouse model of epilepsy. Mice were randomly assigned to four groups; (1) PTZ group that intraperitoneally received PTZ for 10 days, (2) oleuropein group that received oleuropein (20mg/kg) 30 minutes before PTZ administration, (3) dia...
Conclusions and clinical implicationsThese results may support ongoing debates assuming the initial low performance in the memory of L-TLE patients to be directly related with left hippocampal-temporal tissue loss irrespective of epileptic activity. The discovery of the ALF phenomenon explains that standard memory tests are unable to detect memory loss in some patients who are experiencing a significant level of problems with forgetfulness in their daily lives.
This report highlights the importance of both age-related and disease-related variables when diagnosing patients with cognitive decline. PMID: 31886001 [PubMed]
Publication date: Available online 9 November 2019Source: Epilepsy &BehaviorAuthor(s): Kristie Bauman, Orrin Devinsky, Anli A. LiuAbstractCareful study of the clinical outcomes of temporal lobe epilepsy (TLE) surgery has greatly advanced our knowledge of the neuroanatomy of human memory. After early cases resulted in profound amnesia, the critical role of the hippocampus and associated medial temporal lobe (MTL) structures to declarative memory became evident. Surgical approaches quickly changed to become unilateral and later, to be more precise, potentially reducing cognitive morbidity. Neuropsychological studies foll...
