まとめ
機能性/解離性発作(FDS)は、てんかん性発作と比較して、持続的な閉眼、骨盤突き、および長い持続時間を示すことがよくあります。これらの臨床兆候を認識することは、正確な診断と適切な患者管理に役立ちます。
科学分野:
- 神経学
- 臨床神経科学
- 精神医学
背景:
- 機能性/解離性発作(FDS)とてんかん性発作を区別することは、効果的な治療のために非常に重要です。
- 臨床徴候学は早期特定における重要な要素ですが、発作タイプ間には重複が存在します。
研究 の 目的:
- 機能性/解離性発作(FDS)とてんかん性発作の臨床的特徴を比較すること。
- FDSの早期かつ正確な診断のための特定の徴候学的指標を特定すること。
主な方法:
- 機能性/解離性発作(FDS)患者51例および年齢・性別を一致させたてんかん患者51例の発作性徴候学の遡及的分析。
- ビデオ脳波検査(video-EEG)により、すべての診断が確認されました。
- 評価された特徴には、閉眼、頭部/体幹の動き、骨盤突き、後弓反張、顔面しかめ、経過の変動、振戦、発声、意識、および持続時間が含まれました。
主要な成果:
- FDS患者は、持続的な閉眼(90.2%)、骨盤突き(43.1%)、後弓反張(27.5%)、変動する経過(66.7%)、および四肢の振戦(76.5%)(p < 0.001)をより頻繁に示しました。
- FDSエピソードは有意に長く(中央値180秒対66秒、p < 0.001)。
- FDSの独立した予測因子には、持続的な閉眼(オッズ比:56.9)、骨盤突き(オッズ比:8.1)、および発作持続時間(1秒あたりオッズ比:1.011)が含まれました。
結論:
- 持続的な閉眼、骨盤突き、および長い発作持続時間は、FDSの重要な指標です。
- ビデオ脳波検査が利用できない場合、特に診断精度が向上します。
- 不要な抗発作薬の予防と心理的ケアの適時開始。

Angina III: Clinical Manifestations and Assessment
250
Angina manifests as chest pain, tightness, or squeezing discomfort typically located behind the breastbone. It can radiate to the neck, jaw, shoulders, and inner aspects of the upper arms, most commonly the left arm. Patients may experience shortness of breath, fatigue, profuse sweating, dizziness, indigestion, heartburn, palpitations, anxiety, and vomiting as accompanying symptoms. This pain often lasts a few minutes and is triggered by physical exertion, emotional stress, heavy meals, or cold...

Dissociative Disorders
586
Dissociative disorders represent complex psychological conditions characterized by disruptions in consciousness, memory, identity, or perception. These disruptions cause individuals to experience a disconnection from their thoughts, emotions, and memories. The phenomenon is not merely an occasional lapse in attention but a profound alteration in mental functioning that can severely impact daily life.

Seizures: Classification
1.6K
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:

Dissociative Amnesia
610
Dissociative amnesia is a complex psychological condition that manifests as an inability to recall personal information, often tied to traumatic or stressful events. Unlike general amnesia, individuals with this condition retain the ability to perform routine activities and procedural tasks, such as operating a phone or navigating public transportation, yet experience profound gaps in autobiographical memory. These lapses may encompass significant life events, such as suicide attempts or...

Epilepsy and Seizures: Overview
1.3K
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...

Dissociative Identity Disorder
913
Dissociative Identity Disorder (DID), previously termed multiple personality disorder, is a complex psychological condition characterized by the presence of two or more distinct identities or personality states. Each identity exhibits unique patterns of behavior, voice, and mannerisms and may possess separate memories and emotional responses. The alternating control between identities can result in memory gaps and challenges in recalling daily activities, often exacerbating the individual's...
