    Epilepsy is one of the most recognizable neurological diseases, globally. Epilepsy may be accompanied by various complications, including vision impairments, which may severely impact one's quality of life. These visual phenomena may occur in the preictal, ictal and/or postictal periods of seizures. Examples of epilepsy associated visual phenomena include visual aura, visual hallucinations, transient visual loss and amaurosis (blindness). These ophthalmologic signs/symptoms of epilepsy may be temporary or permanent and may vary depending of the type of epilepsy and location of the seizure foci (occipital or temporal lobe). Some visual phenomena may even be utilized to diagnose the epilepsy type, although solely depending on visual symptoms for diagnosis may lead to mistreatment. Some antiseizure medications (ASMs) may also contribute to certain visual disturbances, thereby impacting its therapeutic efficiency for patients with epilepsy (PWE). Although the development of visual comorbidities has been observed diversely among PWE, there may still be a lack of understanding on their relevance and manifestation in epilepsy, which may contribute to the rate of misdiagnosis and the current scarcity in therapeutic relieve. Therefore, this mini narrative review aimed to discuss the common epilepsy associated visual phenomena, based on the available literature. This review also showcased the relationship between the type of visual complications and the site of seizure onset, as well as compared the visual phenomena between occipital lobe epilepsy and temporal lobe epilepsy. Evaluation of these findings may be crucial in reducing the risk of permanent seizure/epilepsy related vision deficits among PWE.

    BACKGROUND: Epilepsy has a high incidence among infants during their first year of life, yet the prognosis can vary significantly. Although considerable research has been conducted on infantile spasms, studies examining infantile-onset epilepsy, excluding infantile spasms, remain limited, particularly concerning the factors influencing outcomes. Therefore, our study aims to elucidate seizure control, developmental outcomes, and prognostic factors in infants with epilepsy during their first year of life, within a single-center study in Malaysia.

    METHODS: We retrieved data from patients who experienced seizures before age 12 months and were followed for over two years, using electronic patient records at Hospital Raja Perempuan Zainab II in Kelantan, a state in Malaysia's east coast. We retrospectively reviewed these records and assessed clinical outcomes based on the last follow-up.

    RESULTS: Of 75 patients, 61 (81.3%) achieved good seizure control or remission. At the last follow-up, 24 (32%) exhibited developmental delay, whereas 19 (25.3%) displayed abnormal neuroimaging. Patients with abnormal background electroencephalographic (EEG) activity, as well as abnormal radiological findings, were more likely to experience poor seizure control and unfavorable developmental outcomes (P

    CONTEXT: Infection and septicaemia may clinically presented with seizure and altered conscious level. In spinal cord injury (SCI) population, they are at risk of having pressure ulcer which can be complicated further with infection and septicaemia.

    FINDINGS: A 40-year-old man with complete T4 SCI and multiple clean and non-healing pressure ulcers at sacral and bilateral ischial tuberosity regions was initially admitted for negative pressure wound therapy (NPWT) dressing. He had an episode of seizure and subsequently had fluctuating altered conscious level before the diagnosis of deep-seated sacral abscess was made and managed. Prior investigations to rule out common possible sources of infections and management did not resolve the fluctuating event of altered consciousness.

    CLINICAL RELEVANCE: We presented an unusual case presentation of septicemia in a patient with SCI with underlying chronic non-healing pressure ulcer. He presented with seizure and fluctuating altered conscious level. Even though a chronic non-healing ulcer appeared clinically clean, a high index of suspicion for deep seated abscess is warranted as one of the possible sources of infection, especially when treatment for other common sources of infections fails to result in clinical improvement.

    In a cross-sectional study of 24 Oriental children with systemic lupus erythematosus (SLE) with a mean age of 11.25 years, 75% were found to have clinical and neurophysiological evidence of cerebral lupus. Seizures were the most common manifestation affecting 11 (61%) of the cases, followed by psychosis in five (27.7%), encephalopathy in five (27.7%), headaches in five (27.7%), personality changes in four (22.2%), stroke in three (16.6%), movement disorders in three (16.6%) and myelitis in one child (5.5%). Four children had cerebral lupus as the presenting manifestation of SLE. Twenty-one children had an electroencephalogram (EEG) of which 11 were normal. Abnormalities detected in the rest included focal sharps, slowing of background and electrodecremental changes. There was a poor correlation of EEG with the clinical presentation. Sixteen children with cerebral lupus had a computed tomogram (CT) of which three were normal. The commonest abnormality was cerebral atrophy with or without infarcts. Only four of the cases had lupus anticoagulant but compliment was reduced in 13. Sixteen of the cases also had renal involvement. Treatment was generally with steroids with only two patients receiving cyclophosphamide for cerebral relapse. Eight children (44%) made a full recovery. Learning disability was the most frequent sequelae affecting one-third of children seen at a 1-year follow up. Four (22%) had epilepsy, two (11%) had motor deficits and one child had optic atrophy. One child died of cerebral haemorrhage during a hypertensive crisis.

    This paper reviews the subject of tuberous sclerosis complex and presents data in eight cases of this condition, admitted to Hospital Universiti Sains Malaysia over a period of 8.5 years. The average age at presentation was 53 months. Seizures were the most common presenting feature. Male to female ratio was 3:1. Family history was present in four patients. All of the patients had one or more skin lesions. Six of them had retinal in six patients. Two patients had renal angiomyolipomas. A high index of hamartomas. Cardiac tumours were found in two patients. Multiple subependymal hamartomas were detected in six patients. Two patients had renal angiomyolipomas. A high index of suspicion and a detailed physical examination is required to diagnose this rare disorder.

    Casein kinase 2 (CK2) is a serine threonine kinase ubiquitously expressed in eukaryotic cells and involved in various cellular processes. In recent studies, de novo variants in CSNK2A1 and CSNK2B, which encode the subunits of CK2, have been identified in individuals with intellectual disability syndrome. In this study, we describe four patients with neurodevelopmental disorders possessing de novo variants in CSNK2A1 or CSNK2B. Using whole-exome sequencing, we detected two de novo variants in CSNK2A1 in two unrelated Japanese patients, a novel variant c.571C>T, p.(Arg191*) and a recurrent variant c.593A>G, p.(Lys198Arg), and two novel de novo variants in CSNK2B in Japanese and Malaysian patients, c.494A>G, p.(His165Arg) and c.533_534insGT, p.(Pro179Tyrfs*49), respectively. All four patients showed mild to profound intellectual disabilities, developmental delays, and various types of seizures. This and previous studies have found a total of 20 CSNK2A1 variants in 28 individuals with syndromic intellectual disability. The hotspot variant c.593A>G, p.(Lys198Arg) was found in eight of 28 patients. Meanwhile, only five CSNK2B variants were identified in five individuals with neurodevelopmental disorders. We reviewed the previous literature to verify the phenotypic spectrum of CSNK2A1- and CSNK2B-related syndromes.

    N-methyl-D-aspartate receptors (NMDAR) play a central role in epileptogensis and NMDAR antagonists have been shown to have antiepileptic effects in animals and humans. Despite significant progress in the development of antiepileptic therapies over the previous 3 decades, a need still exists for novel therapies. We screened an in-house library of small molecules targeting the NMDA receptor. A novel indolyl compound, 2-(1,1-Dimethyl-1,3-dihydro-benzo[e]indol-2-ylidene)-malonaldehyde, (DDBM) showed the best binding with the NMDA receptor and computational docking data showed that DDBM antagonised the binding sites of the NMDA receptor at lower docking energies compared to other molecules. Using a rat electroconvulsive shock (ECS) model of epilepsy we showed that DDBM decreased seizure duration and improved the histological outcomes. Our data show for the first time that indolyls like DDBM have robust anticonvulsive activity and have the potential to be developed as novel anticonvulsants.

    Epilepsy is marked by seizures that are a manifestation of excessive brain activity and is symptomatically treatable by anti-epileptic drugs (AEDs). Unfortunately, the older AEDs have many side effects, with cognitive impairment being a major side effect that affects the daily lives of people with epilepsy. Thus, this study aimed to determine if newer AEDs (Zonisamide, Levetiracetam, Perampanel, Lamotrigine and Valproic Acid) also cause cognitive impairment, using a zebrafish model. Acute seizures were induced in zebrafish using pentylenetetrazol (PTZ) and cognitive function was assessed using the T-maze test of learning and memory. Neurotransmitter and gene expression levels related to epilepsy as well as learning and memory were also studied to provide a better understanding of the underlying processes. Ultimately, impaired cognitive function was seen in AED treated zebrafish, regardless of whether seizures were induced. A highly significant decrease in γ-Aminobutyric Acid (GABA) and glutamate levels was also discovered, although acetylcholine levels were more variable. The gene expression levels of Brain-Derived Neurotrophic Factor (BDNF), Neuropeptide Y (NPY) and Cyclic Adenosine Monophosphate (CAMP) Responsive Element Binding Protein 1 (CREB-1) were not found to be significantly different in AED treated zebrafish. Based on the experimental results, a decrease in brain glutamate levels due to AED treatment appears to be at least one of the major factors behind the observed cognitive impairment in the treated zebrafish.
