1. Seizure

Seizure는 뇌 신경세포의 부적절한 전기 방전으로 인한 비정상적인 신경학적 기능의 발작입니다. 원발성 또는 특발성 발작은 명확한 원인을 찾을 수 없는 경우이고, 이차성 발작은 종양, 외상, 뇌졸중 등의 신경학적 질환으로 인한 경우입니다. 발작 지속 상태(status epilepticus)는 5분 이상 지속되거나 의식 회복 없이 연속적으로 발생하는 경우를 말합니다. 난치성 발작 지속 상태는 두 가지 항경련제 투여에도 불구하고 발작이 지속되는 경우입니다.
2. Pseudoseizure

Pseudoseizure 또는 정신적 비간질성 발작(PNES)은 간질 발작처럼 보이지만 실제로는 비정상적이고 과도한 피질 활동의 발현이 아닌 정신적 원인으로 발생하는 경우를 말합니다. 이는 간질의 변형이 아니라 정신과적 원인에 의한 것입니다. 진단 정확도는 임상 병력 기반 67%, 관찰 기반 75%로 보고되고 있습니다.
3. Differential diagnosis

간질 발작과 PNES를 구분하기 위해서는 다음과 같은 사항을 고려해야 합니다. 1) 발작이 갑작스럽게 시작되는지, 2) 발작이 유발 요인에 의해 발생하는지, 3) 전구 증상이 있는지, 4) 혈중 젖산 수치 변화, 백혈구 및 호중구/림프구 비율 변화 등 검사 결과를 확인해야 합니다. 또한 근간대성 경련, 이상운동 등 다른 신경학적 증상과의 감별도 필요합니다.

1. Seizure

Seizures are a serious medical condition that can have a significant impact on a person's life. They are characterized by sudden and uncontrolled electrical disturbances in the brain, leading to a range of symptoms such as convulsions, loss of consciousness, and abnormal movements. Seizures can be caused by a variety of factors, including brain injuries, genetic disorders, and underlying medical conditions like epilepsy. It is important to recognize the signs and symptoms of a seizure and seek immediate medical attention, as they can be life-threatening if not properly managed. Treatment for seizures typically involves a combination of medication, lifestyle changes, and in some cases, surgical interventions. Anticonvulsant drugs are often prescribed to help control the frequency and severity of seizures, while lifestyle modifications such as stress management and adequate sleep can also play a role in managing the condition. Overall, seizures are a complex and multifaceted medical issue that require a comprehensive approach to diagnosis and treatment. Ongoing research and advancements in the field of neurology are helping to improve our understanding of seizures and develop more effective therapies to improve the quality of life for those affected by this condition.
2. Pseudoseizure

Pseudoseizures, also known as non-epileptic seizures or psychogenic non-epileptic seizures (PNES), are a complex and often misunderstood medical condition. Unlike true seizures, which are caused by abnormal electrical activity in the brain, pseudoseizures are characterized by episodes that resemble seizures but are not accompanied by the same neurological changes. Pseudoseizures are often associated with underlying psychological or emotional factors, such as trauma, stress, or mental health disorders. They can be challenging to diagnose, as the symptoms can be similar to those of epileptic seizures, and may require a comprehensive evaluation by a team of healthcare professionals, including neurologists, psychiatrists, and psychologists. Treatment for pseudoseizures typically involves a combination of psychotherapy, medication, and lifestyle modifications. Cognitive-behavioral therapy (CBT) has been shown to be an effective approach, as it can help patients develop coping strategies and address the underlying psychological factors that may be contributing to their seizure-like episodes. It is important to note that pseudoseizures are a real and valid medical condition, and should not be dismissed or minimized. Individuals with pseudoseizures often face significant challenges and stigma, and it is crucial that they receive compassionate and evidence-based care to manage their symptoms and improve their overall quality of life.
3. Differential diagnosis

Differential diagnosis is a critical component of the medical decision-making process, as it involves the systematic evaluation of various potential causes or conditions that may be responsible for a patient's presenting symptoms. This process is particularly important in the context of seizures and other neurological disorders, where the underlying cause can be complex and multifaceted. When it comes to seizures, the differential diagnosis process involves carefully considering and ruling out a range of potential etiologies, including epilepsy, brain tumors, head injuries, metabolic disorders, and even psychiatric conditions like pseudoseizures. This requires a comprehensive medical history, physical examination, and a variety of diagnostic tests, such as electroencephalography (EEG), neuroimaging, and laboratory studies. Accurate differential diagnosis is crucial for ensuring that patients receive the appropriate treatment and management plan. Misdiagnosis or delayed diagnosis can lead to suboptimal outcomes, as the underlying condition may not be properly addressed. Additionally, the differential diagnosis process can help identify any comorbidities or contributing factors that may be influencing the patient's symptoms, allowing for a more holistic and personalized approach to care. Overall, the differential diagnosis of seizures and other neurological disorders is a complex and nuanced process that requires the expertise of healthcare professionals with specialized training and experience in this field. By carefully considering the various potential causes and ruling out alternative diagnoses, clinicians can work to ensure that patients receive the most appropriate and effective care for their specific needs.
