Seizures are sudden and episodic episodes of disruption of the normal functioning of organs and systems, often of a neurological nature. Seizures can manifest themselves in various forms, including convulsive, mental, vegetative and other disorders. These events can be associated with diseases such as epilepsy, migraine, cardiovascular disorders and others. Seizures often require emergency medical care and can have a significant impact on the quality of life of patients.
History of the disease and interesting historical facts
The study of seizures dates back to ancient times, when doctors and healers tried to understand and treat these mysterious conditions. One of the first records of seizures can be considered records in papyri of ancient Egypt, which described symptoms resembling epilepsy. In ancient Greece, Hippocrates in his works pointed out possible causes of seizures, linking them to disturbances in the brain, while others considered these conditions to be manifestations of divine wrath or possession. In the Middle Ages, seizures began to be placed in the context of religious beliefs and witchcraft.
It was only with the development of medicine in the 16th to 18th centuries that seizures began to be perceived as a medical problem. In the 19th century, studies of the electrical activity of the brain led to a deeper understanding of the mechanism of epilepsy and other types of seizures. In the 20th century, the development of neurophysiology and neuropsychology contributed to significant progress in the diagnosis and treatment of seizures.
Epidemiology
The epidemiology of seizures covers various aspects of their occurrence, including prevalence and incidence. It is estimated that one in ten people worldwide will experience one or more seizures at least once in their lifetime. The incidence of epilepsy, which is one of the most common forms of seizures, is approximately 0.5-1% of the population, with the peak incidence observed in childhood and old age. It is also worth noting that different types of seizures may occur with different frequencies depending on the region and sociocultural factors.
According to a study conducted by the WHO, up to 70% people with epilepsy can be effectively controlled with drug therapy. However, due to social stigma and lack of awareness about the disease, many of the remaining 30% patients continue to experience frequent seizures.
Genetic predisposition to this disease
Some forms of seizures, including epilepsy, have a genetic predisposition. Research shows that more than 25% of epilepsy patients have a family history of the disorder. The genes involved are often associated with neuronal function, suggesting possible abnormalities in neurotransmission or ion channels.
Significant genes include:
- SCN1A — encodes one of the subsets of sodium channels and is associated with syndromes including Dravet syndrome.
- LEMD3 - mutations in this gene are associated with a syndrome of certain forms of epilepsy.
- GABRG2 - participation in the regulation of GABA receptors, which can affect seizure activity.
- CDKL5 - associated with severe forms of epilepsy, usually begins in early childhood.
Risk factors for the development of this disease
Various physical and chemical factors can increase the risk of seizures. The main risk factors include:
- Heredity - having relatives with epilepsy or other neurological conditions.
- Head injuries - Traumatic brain injuries can trigger the onset of epilepsy.
- Infections - meningitis, encephalitis and other infections can trigger the onset of seizures.
- Starch-dependent conditions - internal factors such as metabolic disorders can contribute to the occurrence of attacks.
- Chemicals - alcohol and drug use, and exposure to toxic chemicals.
Diagnosis of this disease
Diagnosis of seizures is based on a comprehensive approach that includes history taking, physical examinations, and laboratory tests. The main symptoms observed during seizures can vary, but often include:
- Cramps
- Loss of consciousness
- Mental disorders (dysphoria, mania)
- Vegetative disorders (sweating, increased heart rate)
Laboratory tests may include:
- Complete blood count and biochemical tests to assess the general condition of the body.
- Electroencephalography (EEG) to record the electrical activity of the brain.
- Magnetic resonance imaging (MRI) to assess structural changes in the brain.
Differential diagnosis includes exclusion of other pathologies such as stroke, infectious diseases and metabolic disorders.
Treatment
Treatment of seizures requires an individual approach and may include drug therapy, as well as surgical and alternative methods.
General treatment is aimed at controlling the frequency and severity of attacks. The main methods are:
- Pharmacological treatment includes the use of anticonvulsants such as valproate, lamotrigine, phenytoin and carbamazepine.
- Surgical treatment - in cases where drug therapy is not effective, removal of foci of pathological activity in the brain may be indicated.
- Other treatments include the ketogenic diet, neurostimulation, and psychotherapy and rehabilitation of patients.
List of drugs used to treat this disease
- Valproate
- Carbamazepine
- Lamotrigine
- Gabapentin
- Topiramate
Disease monitoring
Monitoring patients with seizures involves regular examinations and tracking seizure frequency. Monitoring steps may include:
- Regular visits to a neurologist to assess the effectiveness of treatment.
- An EEG is performed to monitor the electrical activity of the brain and detect changes.
- Discussion of possible side effects of drug treatment.
The prognosis with proper treatment is usually good, but there is a risk of complications such as seizure-related injuries and mental disorders.
Age-related features of the disease
Seizures may present differently depending on the age of the patient. Children often experience myoclonic and absence seizures, while older adults may experience more complex forms such as tonic-clonic seizures. In addition, awareness and knowledge of the condition may vary depending on the age group.
