Etiological profile of new-onset seizures among adult Egyptians

Seizure Considerations in Older Adults and Geriatric Patients

Older adults account for 25% of first-time seizures, with many of these seizures caused by accumulated injuries and insults to the brain and comorbidities associated with aging or as a result of a life-threatening comorbidity, yet seizures in older adults are often so subtle that they are not recognized or treated. Once an older adult has 1 seizure, they are at higher risk of more seizures and ultimately a diagnosis of epilepsy. Epilepsy affects quality of life and safety and may jeopardize life itself in the older adult; thus, it is important to be able to recognize seizures in older adults and know what to do.

Efficacy of a pre-specified timeline-based treatment protocol in children with acute repetitive seizures or seizure clusters

Objectives

Acute repetitive seizures (ARSs) are one of the few commonly encountered neurological emergencies in children. There is a need for an appropriate timeline-based treatment protocol, which will be shown to be safe and efficacious in a clinical study.

Materials and Methods

This was a retrospective chart review to determine the efficacy of a pre-specified treatment protocol for the management of ARSs in children aged 1-18 years. The treatment protocol was specifically applied in children with a diagnosis of epilepsy and not critically ill, who met the criteria for ARSs, with the exemption of new onset of ARSs. The first tier of treatment protocol focused on intravenous lorazepam, optimization of dose of existing anti-seizure medications (ASMs), and control of triggers like acute febrile illness, while second-tier focused on adding one or two additional ASMs, commonly used in cases with seizure clusters or status epilepticus.

Results

We included the first 100 consecutive patients (7.6 ± 3.2 years, 63% boys). Our treatment protocol was successful in 89 patients (58 and 31 required first-tier and second-tier treatment). The absence of pre-existing drug-resistant epilepsy and the presence of acute febrile illness as a triggering factor (P = 0.02 and 0.03) were associated with the success of the first tier of the treatment protocol. Excessive sedation (n = 29), incoordination (n = 14), transient gait instability (n = 11), and excessive irritability (n = 5) were the most common adverse effects observed during the initial 1 week.

Conclusion

This pre-specified treatment protocol is safe and efficacious in controlling ARSs in cases with established epilepsy who are not critically sick. External validation from other parts of the world/centers and a more diverse epilepsy population are required before generalizing the protocol into clinical practice.

Seizure in geriatric population - An unheeded integer

Background

Epilepsy is one of the most prevalent neurological conditions among the elderly. Age-related epileptogenic disorders as well as the ageing itself pose a risk for seizures in the elderly. The lack of witnesses, non-specific symptoms, and transient symptoms make the diagnosis challenging in the elderly.

Aim

This study aimed to assess the various presentation and aetiology for the seizure disorder in the elderly population.

Materials and Methods

A total of 125 elderly patients ≥60 years with new onset seizure were included in the study. Demographic data, co-morbidities, and clinical presentation of seizure were elicited. Hemogram, liver and renal function tests, random blood sugar, electrolytes, and serum calcium were analysed. Computed tomography (CT), magnetic resonance imaging (MRI) brain, and electroencephalogram (EEG) were performed.

Results

Seizure was seen predominantly in the males with age group of 60-70 years. Generalized tonic-clonic seizure was the commonest presentation, followed by focal seizures. The leading causes of seizures were cerebral vascular accidents, metabolic conditions, and alcohol. CT brain was abnormal in 49%, and 73% of the patients showed abnormality in MRI brain. EEG was abnormal in 17.3% of patients. Temporal lobe infarction was the commonest, trailed by parieto-temporal and frontal lobe involvement.

Conclusion

Seizures in the elderly have varied clinical signs and aetiology. An awareness about these atypical presentation and aetiology is essential for the early diagnosis and management to prevent morbidity.

Evaluation of Acute Symptomatic Seizures and Etiological Factors in a Tertiary Care Hospital From a Developing Country

Introduction: The etiologies of acute symptomatic seizures (ASS) differ across the globe. We aimed to evaluate the etiological spectrum of acute seizures and to observe the pattern of seizure types among study participants.

Methodology: We conducted this prospective study from 2016 to 18. We included all patients aged 20 years or older, presenting with ASS. We excluded those with pseudoseizures. We performed appropriate descriptive analyses to describe the demographic details, etiology of ASS, and pattern of ASS.

Results: One hundred and thirty-eight patients were enrolled, constituting about 0.8% of total hospital admissions. The mean age at presentation was 44.33 ± 17.73 years. The most common etiologies for ASS were cerebrovascular accidents (CVA - 32.6%), neuroinfections (26.8%), metabolic derangements (13%), alcohol withdrawal (10.9%), and intracranial tumors (4.3%). 71% of the patients presented with only a single episode of ASS. The predominant type of seizure was generalized tonic-clonic seizures, seen in 70.2% of all patients, followed by focal with the bilateral tonic-clonic type (15.9%) and focal seizures (10.1%). New-onset seizures presenting as status epilepticus were observed in 3.6%.

Discussion: CVA and neuroinfections were the most common causes of ASS in our study, highlighting the need for community awareness of these conditions and the need to seek rapid care. The majority of our patients had only a single episode of seizures, with generalized seizures being the most common type, followed by focal onset seizures.
