Early childhood autism, or autism spectrum disorders, is an extremely heterogeneous group of conditions that share similar symptoms of dysontogenesis. The most significant comorbidity in patients with autism is epilepsy, which is still associated with a variety of controversies. The present article covers the most controversial aspects of comorbidity between autism and epilepsy, including the impact of psychopharmacotherapy on the risk of epilepsy, clinical significance of epileptiform activity on the electroencephalogram in patients without epilepsy, and criteria for and prevalence of autistic epileptiform regression syndrome. We found that there is still a lack of reliable evidence for the majority of issues related to the combination of autism and epilepsy. We emphasize the need for further studies. We also provide a detailed description of the history, criteria, prevalence, and clinical examples of autistic epileptiform regression syndrome.

Electroencephalographic Monitoring of the Brain Functional Condition in Modern Ukranian Schoolchildren

2020

The aim: To monitor the brain functional state of generally healthy Ukrainian schoolchildren according to computer electroencephalography (EEG). Materials and methods: EEG examination of 125 practically healthy (according to medical records) schoolchildren of both sexes, which were divided into 3 age groups: 1) 8–12 years old (n = 49); 2) 13–16 years old (n = 42); 3) 17–18 years old (n = 34). EEG was recorded at rest with eyes closed and during functional tests (eye opening, hyperventilation). Visual and spectral analyzes of the EEG were carried out, types of EEG were determined according to A.E. Zhirmunskaya. (1991) in the adaptation of N.L. Gorbachevskaya et al. (1999). Results: The peak frequency of alpha activity is in the range of 9 to 11.5 Hz, with a tendency to increase as you grow older. A disorganized type of EEG with a predominance of alpha activity dominates with an organized type of EEG. For most schoolchildren, normal EEG reactivity predominates in response to functional tests. The detection rate of short fragments of pathological activity in the background did not exceed 8%, but increased to 20% with hyperventilation. Conclusions: Only a third of modern Ukrainian schoolchildren classified as “healthy” have a physiological type of EEG, which indicates the optimal functional state of the brain. The remaining part of generally healthy schoolchildren have EEG changes, which reflect initial functional disorders mainly at the level of nonspecific structures and the brain stem.
