To investigate the course of epilepsy and seizure control during pregnancy. 105 pregnant women with epilepsy were studied prospectively during the period from 2013 to 2017. The average age at the onset of epilepsy was 17.4 ± 0.5 years. Seizures during pregnancy were observed in 76 (72.4 ± 4.4%) women. Eleven (10.5 ± 3.0%) women had their first seizure during current pregnancy. Among those 94 women who were diagnosed with epilepsy before pregnancy, 29 (30.9 ± 4.8%) remained seizure free; seizure frequency increased in 27 (28.7 ± 4.7%), decreased in 24 (25.5 ± 4.5%) women, in 14 (14.9 ± 3.7%) remained unchanged. Among 15 women who were seizure free for the 1 year prior to pregnancy 11 (73.3 ± 11.4%) women remained seizure free during pregnancy. The worsening in seizure control during pregnancy occurred in 22 (35.5 ± 6.1%) of 62 women with focal epilepsy and 5 (15.6 ± 6.4%) of 32 with idiopathic generalized epilepsy (OR 2.97, 95% CI 1.0-8.81). Non-compliance with the antiepileptic drug therapy was observed in 20 (19.0 ± 3.8%) pregnant women, seizure frequency increased in 18 (90.0 ± 6.7%) of them compared with 5 (9.8 ± 4.2%) of 51 of those who followed correct antiepileptic drug regimen (p < 0.001). The risk of seizures during pregnancy was lower in women who were seizure-free for the 1 year prior to pregnancy; focal epilepsy was associated with an increased risk of seizure relapse during pregnancy; non-compliance with the antiepileptic drug therapy and inappropriate treatment may lead to worsening of seizure control and to the status epilepticus during pregnancy.

Epilepsy and Seizures: Overview01:24

Epilepsy and Seizures: Overview

Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...

Seizures: Classification01:13

Seizures: Classification

Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:

Control System Problem01:21

Control System Problem

In an open-loop system, such as a basic thermostat, the poles of the transfer function influence the system's response but do not determine its stability. However, when feedback is introduced to form a closed-loop system, such as an advanced thermostat that adjusts heating based on room temperature, stability is governed by the new poles of the closed-loop transfer function.
When forming a closed-loop system, issues can arise if the poles cross into the unstable region, leading to potential...

Combinatorial Gene Control02:33

Combinatorial Gene Control

Combinatorial gene control is the synergistic action of several transcriptional factors to regulate the expression of a single gene. The absence of one or more of these factors may lead to a significant difference in the level of gene expression or repression.
The expression of more than 30,000 genes is controlled by approximately 2000-3000 transcription factors. This is possible because a single transcription factor can recognize more than one regulatory sequence. The specificity in gene...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Control Systems

Control systems are everywhere in contemporary society, influencing diverse applications from aerospace to automated manufacturing. These systems can be found naturally within biological processes, such as blood sugar regulation and heart rate adjustment in response to stress, as well as in man-made systems like elevators and automated vehicles. A control system is essentially a network of subsystems and processes that collaboratively convert specific inputs into desired outputs.
