DEFINISI Epilepsi suatu keadaan yg ditandai oleh bangkitan epilepsi berulang, berselang lebih dari 24 jam yg timbul tanpa provokasi. Bangkitan epilepsi (epileptic seizure) manifestasi klinik yg disebabkan oleh aktivitas listrik otak yg abnormal dan berlebihan dari sekelompok neuron. Manifestasi klinik ini terjadi secara tiba-tiba dan sementara perubahan perilaku yg stereotipik, dpt menimbulkan gangguan kesadaran, motorik, sensorik, otonom, ataupun psikik.

Key point In epilepsy, there is a problem with the electrical messages in the brain.

Seizures disrupt the way the brain works for a short time.
Key point People with epilepsy experience sudden bursts of electricity in their brain - called a SEIZURE. Seizures disrupt the way the brain works for a short time. This burst of electrical activity – a seizure - causes the messages in the brain to become muddled and so it stops it from working properly. Changes behaviour or feelings of person.

A seizure is a symptom of epilepsy
What Is the Difference Between Epilepsy & Seizures? A seizure is a brief, temporary disturbance in the electrical activity of the brain Epilepsy is a disorder characterized by recurring seizures (also known as “seizure disorder”) To understand epilepsy, it is important to review the difference between epilepsy and seizures. Epilepsy is a generic term used to define a variety of disorders characterized by recurring seizures. A diagnosis of epilepsy means that a person has an underlying condition, such as a brain injury, that affects the delicate systems which govern how electrical energy behaves in the brain, making it susceptible to recurring seizures. A seizure is a brief, temporary disturbance in the electrical activity of the brain. Seizures are a symptom of epilepsy. However, having a seizure does not necessarily mean that a person has epilepsy. There are other causes of seizures, including high fever, kidney failure, or lack of oxygen. Epilepsy is not contagious. You cannot catch epilepsy from someone else and nobody can catch it from you. Many misconceptions surround epilepsy, and sometimes people inadvertently add to the negative image of the disorder by choice of language. Like all individuals with a disability, persons with epilepsy dislike labels, such as “he’s an epileptic.” Epilepsy is a condition that a person has, not what they are. The preferred terminology is “person with epilepsy.” In addition, epilepsy should be referred to as a “disorder,” since it is not a disease by definition. It is a disorder characterized by a recurring disturbance in the electrical activity of the brain. A seizure is a symptom of epilepsy Neurology Department Hasanuddin University Muhammad Akbar 9

ILAE CLASSIFICATION OF SEIZURES
Partial seizures have onset in part of the brain; synonymous terms that are frequently used include localization-related or focal seizures. Partial seizures are divided into two main types, depending on whether or not consciousness is fully preserved. During simple partial seizures, consciousness is preserved; the person is alert, can respond to questions or commands, and can remember what occurred during the seizure. During complex partial seizures, consciousness is altered or lost; the ability to pay attention or respond to questions or commands is thus impaired or lost. Often, there is no memory of what happened during all or part of the complex partial seizure. The distinction between simple and complex partial seizures is critical, because activities such as driving and operating dangerous machinery must be restricted in patients with uncontrolled complex partial seizures; restrictions for people with only simple partial seizures depend on the specific seizure manifestations (and, for driving, on regulations in a particular state). Partial onset seizures may progress to secondarily generalized seizures. Secondarily generalized seizures ultimately involve motor activity on both sides of the body and can be difficult to distinguish from primary generalized seizures.
15
ILAE CLASSIFICATION OF SEIZURES
Generalized seizures affect both cerebral hemispheres from the beginning of the seizure. They produce loss of consciousness, either briefly or for a longer period of time, and are sub-categorized into several major types: absence, myoclonic, atonic, tonic, and tonic-clonic.

Diagnosis EEG CT-scan MRI Lain-lain
Pasien didiagnosis epilepsi jika mengalami serangan kejang secara berulang Untuk menentukan jenis epilepsinya, selain dari gejala, diperlukan berbagai alat diagnostik : EEG CT-scan MRI Lain-lain Neurology Department Hasanuddin University Muhammad Akbar
23
DIAGNOSIS EPILEPSI PEDOMAN UMUM 3 langkah:
Memastikan apakah kejadian yg bersifat parosksismal adalah mrpk bangkitan epilepsi Apabila BENAR terdpt bangkitan epilepsi, tentukan Tipe Bangkitan (klasifikasi ILAE 1981) Tentukan Etiologi dan sindroma epilepsi, atau penyakit epilepsi apa yg diderita pasien (klasifikasi ILAE 1989)
24
DIAGNOSIS EPILEPSI – Anamnesis (1)
Langkah pertama (lihat slide sebelumnya), ditempuh melalui: ANAMNESIS Gejala sebelum, selama, dan pasca bangkitan Ada tidaknya penyakit yg diderita yg mungkin menjadi penyebab Usia awitan, durasi, frekuensi, interval terpanjang antar bangkitan Riwayat epilepsi sebelumnya dan respons terhadap terapi (dosis, kadar OAE, kombinasi terapi) Riwayat epilepsi dlm keluarga
25
DIAGNOSIS EPILEPSI – Anamnesis (2)
Riwayat keluarga dgn penyakit neurologik lain, psikiatrik, atau sistemik Riwayat saat dlm kandungan, kelahiran, dan perkembangan bayi/anak. Riwayat bangkitan neonatal/kejang demam Riwayat trauma kepala, infeksi SSP, dll
26
DIAGNOSIS EPILEPSI – Pemeriksaan Fisis
P. FISIS UMUM Amati tanda2 gangguan yg berhub dgn epilepsi, mis: trauma kepala, infeksi telinga, kongenital, kecanduan alkohol, kelainan kulit (neurofakomatosis), dll P. FISIS NEUROLOGIS Amati adanya gejala neurologik fokal atau difus, Todd’s paralysis, dll
27
DIAGNOSIS EPILEPSI – Pemeriksaan Penunjang
EEG Rekaman EEG paling berguna pada dugaan suatu bangkitan. EEG membantu menunjang diagnosis dan penentuan jenis bangkitan maupun sindroma epilepsi, dan kadang2 dpt membantu menentukan prognosis dan penentuan perlu/tidaknya pengobatan AED. Brain Imaging: CT Scan kepala, MRI, PET, SPECT Laboratorium

First Aid for Seizures Stay calm and track time
Protect head, remove glasses, loosen tight neckwear Move anything hard or sharp out of the way Turn person on one side, position mouth to ground Check for epilepsy or seizure disorder ID Understand that verbal instructions may not be obeyed Stay until person is fully aware and help reorient them Call ambulance if seizure lasts more than 5 minutes or if it is unknown whether the person has had prior seizures This graphic shows general measures to assist a person who is having a seizure. First, stay calm and reassure other people. Track how long the seizure lasts. Protect the person by helping them avoid hazards. Place something soft under the head (a coat, T-shirt or similarly appropriate item that’s handy); if the person is wearing glasses, remove them. Loosen any clothing that is tight-fitting around the neck. With a generalized tonic-clonic seizure, turn the person on one side to keep the airway clear. Check for an epilepsy or seizure disorder ID, and wait for the seizure to end. Understand that verbal instructions may not be obeyed. Finally, stay until the person is fully aware and help reorient them to their surroundings. Call an ambulance if the seizure lasts more than 5 minutes, unless you know that the person’s seizures typically last longer than 5 minutes. Remember, unless you are a primary caregiver who has been trained in use of a special medication, or you have been shown how to use a special VNS magnet, there is NOTHING you can do to stop a seizure -- it will run its own course. You CAN protect the person from injury, observe the seizure, call for an ambulance if necessary, and reassure others that this is just a seizure and everything will be just fine in a few moments. NOTE: If asked, the medication is diazepam rectal gel (Diastat) or a liquid form of diazepam for rectal administration. It is for family/caregiver/nurse use only, not a casual first aid. Question: Sometimes things we do with good intentions can actually be dangerous to the person having a seizure. Can you think of things that may be harmful?

Hal-hal yg perlu diperhatikan dalam pengobatan epilepsi :
Tujuan pengobatan : membebaskan penderita dari serangan epilepsi dengan dosis yang memadai tanpa menimbulkan gejala toksik pengobatan epilepsi : sifat individual dan berlangsung lama, minimal 2-3 thn bebas serangan Sekitar 75% kasus dapat ditanggulangi baik dengan satu / kombinasi obat Dianjurkan pengobatan dengan satu jenis obat Neurology Department Hasanuddin University Muhammad Akbar
62
Prinsip umum terapi epilepsi:
monoterapi lebih baik mengurangi potensi adverse effect, meningkatkan kepatuhan pasien, tidak terbukti bahwa politerapi lebih baik dari monoterapi dan biasanya kurang efektif karena interaksi antar obat justru akan mengganggu efektivitasnya dan akumulasi efek samping dg politerapi hindari atau minimalkan penggunaan antiepilepsi sedatif toleransi, efek pada intelegensia, memori, kemampuan motorik bisa menetap selama pengobatan jika mungkin, mulai terapi dgn satu antiepilepsi non-sedatif, jika gagal baru diberi sedatif atau politerapi berikan terapi sesuai dgn jenis epilepsinya Memperhatikan risk-benefit ratio terapi Penggunaan obat harus sehemat mungkin dan sedapat mungkin dalam jangka waktu pendek Neurology Department Hasanuddin University Muhammad Akbar
63
mulai dengan dosis terkecil dan dapat ditingkatkan sesuai dg kondisi klinis pasien penting : kepatuhan pasien ada variasi individual terhadap respon obat antiepilepsi perlu pemantauan ketat dan penyesuaian dosis jika suatu obat gagal mencapai terapi yang diharapkan pelan-pelan dihentikan dan diganti dengan obat lain (jgn politerapi) lakukan monitoring kadar obat dalam darah jika mungkin, lakukan penyesuaian dosis dgn melihat juga kondisi klinis pasien Neurology Department Hasanuddin University Muhammad Akbar
64
Kegagalan pengobatan tergantung dari beberapa faktor:
Faktor penderita : ketidak mampuan dalam : Minum obat Hidup teratur akibat faktor : keluarga lingkungan pendidikan Cegah faktor provokasi Jenis epilepsi Jenis / dosis obat yg tak tepat / optimal

Obat-obat anti epilepsi
Obat-obat yang meningkatkan inaktivasi kanal Na+: Inaktivasi kanal Na menurunkan kemampuan syaraf untuk menghantarkan muatan listrik Contoh: fenitoin, karbamazepin, lamotrigin, okskarbazepin, valproat Obat-obat yang meningkatkan transmisi inhibitori GABAergik: agonis reseptor GABA meningkatkan transmisi inhibitori dg mengaktifkan kerja reseptor GABA contoh: benzodiazepin, barbiturat menghambat GABA transaminase konsentrasi GABA meningkat contoh: Vigabatrin menghambat GABA transporter memperlama aksi GABA contoh: Tiagabin meningkatkan konsentrasi GABA pada cairan cerebrospinal pasien mungkin dg menstimulasi pelepasan GABA dari non-vesikular pool contoh: Gabapentin Neurology Department Hasanuddin University Muhammad Akbar

Factors That Affect the Choice of Drug
Seizure type/ Epilepsy syndrome Side effects & safety Patient age Ease of Use Lifestyle Age, Sex, Childbearing potential Other medications Since drug therapy is usually the first treatment used, let’s start by talking about it. Different types of seizures and epilepsy syndromes have unique features, which may affect the choice of medication, since some drugs are more effective against specific seizures and syndromes. Achieving good control of seizures with drug treatment generally depends on choosing the right drug, minimizing the number of drugs prescribed, and educating the patient and family to encourage daily use as prescribed. Other factors that can affect the choice of drug include potential side effects, the dosing regimen -- whether it is simple or difficult to follow -- the age of the patient, childbearing potential, use of other medications, lifestyle, and, in some cases, cost. Whenever possible, using one drug is preferred. This drug may be prescribed in increasing doses until seizures are controlled or a side effect occurs. If the drug is not effective, or if side effects are hard to live with, this drug will probably be gradually stopped while another one is slowly introduced. Question: How many of you had to try more than one drug before finding one that effectively reduced your seizures? What was the most common reason for changing the medication?

74
Ketogenic Diet Based on finding that starvation -- which burns fat for energy -- has an antiepileptic effect Used primarily to treat severe childhood epilepsy, has been effective in some adults & adolescents High fat, low carbohydrate and protein intake Usually started in hospital Requires strong family commitment The ketogenic diet is not a drug; however, it helps the body to make substances that have an antiepileptic effect. The diet is based on the observation that starvation, which burns fat for energy and produces ketones, has an antiepileptic effect. The goal of the diet is to make the body get its energy from fat and become ketotic. The diet is used primarily to treat severe childhood epilepsy. Persons who follow the diet are instructed to eat foods high in fat and low in carbohydrate and protein. Usually, the diet is started in the hospital so that physicians may monitor the progress. The exact reasons why the diet works remain unclear. Medical studies suggest that about one-third of patients are substantially helped, another third have some reduction in seizure, and one third have no change. Children may be kept on the diet for months or years. There are side effects, but not all children experience them. Like antiepileptic drugs, the ketogenic diet should be tapered rather than stopping abruptly. A great deal of care must be taken when the diet is used in children taking medications, since these may contain sugar to make them more palatable to the child. Parent and family education and a strong family commitment to the diet, plus administration by a doctor and dietician trained in its use, are generally considered vital to success. People with epilepsy should not fast in the hope that it will help their seizure; in fact, fasting may trigger seizures. The keto diet is serious medicine, with its own set of side effects, and should never be tried without medical advice.
