“…It should not be forgotten that any Among the neuropsychiatric clinical features in atypical ESES, ADHD-like symptoms are prominent and seem to be related positively to SWI [40]. Acquired visual agnosia may be found in CSWS, as suggested in the case reported by Van Iterson et al: a male aged almost 7 years presenting CSWS, prevailing in the left posterior regions, who lost the skill of recognizing familiar faces and naming pictures [41]. Kuki et al reported acquired Kanji (morphogram) dysgraphia associated with visual processing impairment in two children with CSWS prevailing in the occipito-temporal region, in which functional neuroimaging showed a dysfunction located in the left posterior temporal lobe [42].…”

In the context of childhood epilepsy, the concept of continuous spike–waves during slow sleep (CSWS) includes several childhood-onset heterogeneous conditions that share electroencephalograms (EEGs) characterized by a high frequency of paroxysmal abnormalities during sleep, which have negative effects on the cognitive development and behavior of the child. These negative effects may have the characteristics of a clear regression or of a slowdown in development. Seizures are very often present, but not constantly. The above makes it clear why CSWS have been included in epileptic encephalopathies, in which, by definition, frequent EEG paroxysmal abnormalities have an unfavorable impact on cognitive functions, including socio-communicative skills, causing autistic features, even regardless of the presence of clinically overt seizures. Although several decades have passed since the original descriptions of the electroclinical condition of CSWS, there are still many areas that are little-known and deserve to be further studied, including the EEG diagnostic criteria, the most effective electrophysiological parameter for monitoring the role of the thalamus in CSWS pathogenesis, its long-term evolution, the nosographic location of Landau–Kleffner syndrome, standardized neuropsychological and behavioral assessments, and pharmacological and non-pharmacological therapies.

“…Agnosia is an inability to identify and recognize objects, sounds or persons using either one or more of their senses even though the senses have a normal function (Kumar, 2023). Visual agnosia has been described as a group of neurological disorders in which the affected individual cannot recognize some or all aspects of an object by sight but by other means such as sound or touch (Barton, 1999).…”

“…The deficit in vision is unexplainable by language problems, memory, attention, or unfamiliarity with the stimuli in question. It is an impairment of the ability to recognize using vision despite an otherwise normal visual acuity, visual field, color vision, language memory and brightness discrimination (Kumar, 2023). One of the earliest experiments was observed by Munk, who described some dogs who avoided some objects in the environment although they could not recognize it.…”

Results revealed no clinical seizures during period of treatment, normal intelligence, normal to high level for retention and learning, but severe difficulties with visual memory which was persistent (van Iterson et al, 2021). Selective visual perception abnormalities such as visual agnosia could result from a damage to the brain with preservation of other visual functions (Matha, 1990).…”

BACKGROUND: Visual agnosia is a significant cause of visual morbidity affecting some patients with neurological disorders. These disorders could range from vascular, degenerative, traumatic amongst others. It is usually visually disabling for the sufferers, who are usually being managed by the neurologist, psychiatrist, or a combination of both. Depending on the area of the brain involved, agnosia could vary in presentations. Furthermore, visual agnosia specifically may also vary in type, and may and may not occur in the presence of other neurological signs and symptoms. Knowledge of the presentation patterns of visual agnosia, could help in early recognition and prompt treatment and/or rehabilitation for the individuals affected.AIM: This study aims to find out the presentation patterns for visual agnosia amongst the sufferers in patients with neurological diseases METHOLOGY: A hospital based observational study (case series/report). RESULTS: Results showed diverse neurological presentations for patients with visual agnosia with all the cases having abnormality of the optic nerve 8(100%). Different areas of the brain were involved. However, the majority, 3 out of the 8 (cases (37.5%) had affectation of the occipital lobe. The other associated neurological signs include hemiparesis, tremors, involuntary muscle movement, cranial nerve abnormalities amongst others. The neurological diseases in this study presenting with visual agnosia include stroke, multiple sclerosis, Parkinson's disease, degenerative dementia, and traumatic brain injury.DATA ANALYSIS: Data was entered and analyzed using IBM SPSS version 25 software. Student T test would be used for the numerical variables obtained in the study while ANOVA would be used for the different categorical variables. The mean, standard deviation and percentages of the variable would be determined. Confident interval of 95% and a p value of <0.05 would be considered significant.CONCLUSION: Visual agnosia may occur in patients with diverse neurological diseases. It may be more common than previously diagnosed as patients may not complain of it unless asked or elicited yet could severely affect the quality of life of the affected individuals. The presentation patterns may also vary depending on the underlying neurological pathology and type of visual agnosia. Adequate recognition and management of visual agnosia is key in ensuring the best prognosis for those affected.

Introduction In children with epilepsy, comorbidities are frequent. In dyslexia, comorbidities are increasingly acknowledged. Little is known about temporal aspects (dyslexia antedating or postdating epilepsy onset, time interval), epilepsy types, and dyslexia phenotypes. Method From over 1000 files of children with epilepsy, 51 cases were retrospectively identified with a formal diagnosis of dyslexia. Ages at diagnoses of dyslexia and epilepsy, epilepsy variables, and dyslexia-related neuro-cognition (phoneme deletion and rapid letter naming) were recorded. Analyses Temporal variables, epilepsy variables, and neuro-cognition were analyzed with chi-squared, t tests, ancova, and generalized linear models. Results Duration of epilepsy to diagnosis of dyslexia ranged from − 5.5 years (dyslexia antedating epilepsy) to 10.1 years. In 35% of the children, diagnosis of dyslexia antedated the emergence of epilepsy. Dyslexia was seen across seizure types, with some preference for temporal lobe and rolandic epilepsy; rates for antedating and postdating dyslexia were similar. Notably, encephalopathic development was also seen. No specific dyslexia phenotype was seen. Children with dyslexia diagnoses after or in close temporal relationship to diagnoses of epilepsy (shortly before or after) scored lower on phonology and naming. Conclusion Antedating and postdating dyslexia can be seen in all epilepsy types. In a natural setting, dyslexia may antedate or postdate the emergence of epilepsy by several years. Around the time the epilepsy is about to surface, scores on dyslexia-related neuro-cognitive tasks are lowest, suggesting a bidirectional effect of the seizure condition on cognition. Encephalopathic development may be mimicking dyslexia criteria in some cases.
