Dravet Sendromu
Özet
Dravet Sendromu (DS), erken çocukluk döneminde başlayan, genellikle pleomorfik nöbetler, bilişsel gerileme ve davranışsal anormalliklerle karakterize nadir görülen ve inatçı bir epileptik ensefalopatidir. Hastaların büyük çoğunluğunda SCN1A genindeki de novo mutasyonlar temel nedendir ve klinik tanı genellikle ILAE kriterlerine göre konulmaktadır. Tedavide amaç nöbet sıklığını azaltmak olup, bazı antiepileptik ilaçlardan kaçınılması kritik öneme sahiptir; tedavi stratejileri sıklıkla çoklu ilaç kullanımı, ketojenik diyet ve yeni nesil farmakolojik ajanları içermektedir. Prognozu genellikle zayıf olan bu sendromda, hastaların bilişsel fonksiyonlarını ve yaşam kalitesini korumak için erken teşhis ve multidisipliner yönetim hayati değer taşır.
Dravet Syndrome (DS) is a rare and intractable epileptic encephalopathy that begins in early childhood, typically characterized by pleomorphic seizure activity, cognitive regression, and behavioral abnormalities. In the vast majority of patients, de novo mutations in the SCN1A gene are the underlying cause, and clinical diagnosis is generally established based on ILAE criteria. The goal of treatment is to reduce seizure frequency, making the avoidance of certain contraindicated antiepileptic drugs critically important; management strategies often involve polytherapy, the ketogenic diet, and newer pharmacological agents. Given its generally poor prognosis, early diagnosis and multidisciplinary management are essential to protect the cognitive functions and quality of life of patients.
