Abstract

Objective: Collaboration among medical facilities is crucial to deliver comprehensive epilepsy care to a diverse and large population of people with epilepsy. We conducted a survey among medical facilities of various sizes throughout Japan to investigate the status of epilepsy care delivery, functioning, and referral. Methods: With the cooperation of the Japan Neurological Society (1428 facilities), Japanese Neurosurgical Society (3489 specialists), and Epilepsy Care Network (948 facilities), a questionnaire was mailed to 5865 locations that provide epilepsy care in Japan. The facilities were classified into clinics (19 beds or less), small hospitals (SH, 20–199 beds), large hospitals (LH, 200 beds or more), and epilepsy centers (EC). The status of epilepsy care delivery, functioning, and referral was compared among the four groups. Results: Responses were received from 1014 facilities (17.3% response rate). After excluding duplicate responses, 957 facilities were analyzed (394 clinics, 149 SH, 388 LH, 26 EC). EC responded "manageable" in more items of epilepsy care functions in general, especially those related to epilepsy surgery, compared to LH with similar facility size. However, EC responded being less manageable in psychiatric service (61.5%), dietary therapy (46.2%), rehabilitation (53.8%), and patient employment support (61.5%). The percentage of facilities that responded "always able to refer" was highest in clinics (67.6%) and the lowest in EC (40%). Referral difficulties were more commonly encountered in EC, and less common in clinics. In EC, the most common reason for inability to refer was patient or family refusal (64%). Significance: We have clarified the epilepsy care delivery, functioning, and referral in facilities of various sizes in Japan. This study highlights the issues of downward referral and patient stagnation in EC, which have not received much attention. Plain Language Summary: A nationwide survey of healthcare facilities ranging in size from small clinics to large hospitals in Japan examined medical care delivery and patient referrals related to epilepsy. Compared to other facilities, epilepsy centers provided a variety of medical services to people with epilepsy but were inadequate in addressing psychiatric symptoms, providing dietary therapy, rehabilitation, and patient employment support. Referrals from epilepsy centers to other medical facilities were often refused by patients and their families. This results in patient crowding at epilepsy centers [ABSTRACT FROM AUTHOR]

Abstract

Aims. Hyperkinetic seizures are usually associated with frontal lobe epilepsy. However, some patients have hyperkinetic seizures of temporal lobe origin. The semiological differences in hyperkinetic seizures between frontal and temporal lobe epilepsy have not been well studied. Here, we retrospectively assessed ictal semiology in order to distinguish between hyperkinetic seizures of frontal lobe origin and those of temporal lobe origin. Methods. We retrospectively reviewed data on patients who had undergone surgery for hyperkinetic seizures of temporal or frontal lobe origin and achieved favourable seizure outcomes (Engel Class I) with a minimum postoperative follow‐up of 24 months. We reviewed seizure histories, imaging reports, video‐EEG monitoring data, operative records, and pathological findings. We analysed and compared the hyperkinetic semiology of video‐recorded seizures of temporal lobe origin and those of frontal lobe origin. Results. Forty hyperkinetic seizures in eight patients (seven adult patients and one 12‐year‐old patient) with temporal lobe epilepsy and 45 hyperkinetic seizures in nine patients (eight adult patients and one 16‐year‐old patient) with frontal lobe epilepsy were analysed. Emotional facial expressions (such as fear, laughing, or anger), bilateral forceful elbow flexion, bilateral forceful grasping, facial flushing, and bilateral facial contraction were observed significantly more frequently in seizures of frontal lobe origin. Oroalimentary automatisms, seizures during wakefulness, salivation, and bilateral drop of the corners of the mouth were observed significantly more frequently in seizures of temporal lobe origin. Conclusions. Observation of a number of signs during hyperkinetic manifestations may help to predict whether a seizure originates from the frontal lobe or the temporal lobe.

Abstract

Epilepsy is defined as a chronic disorder that presents with recurrent episodes of unprovoked seizures. Epileptic seizures are caused by excessive excitation of cortical neurons. The condition has various etiologies and comorbidities. Here, we introduce the definition of epilepsy and classify it based on the newly proposed ILAE (International League Against Epilepsy) classification. In addition, we explain the process of diagnosing epilepsy and delineating the epileptic focus by presenting a case description. Transient functional alterations occur in an epileptic focus only during seizures. Thus, epileptologists are required to record a detailed history and examine its semiology to determine the epileptic focus based on knowledge in neuroscience and epileptology.
