Huzursuz Bacaklar Sendromu (HBS), dinlenmekle veya uykuyla ortaya çıkan ve bacaklarını hareket ettirmekle hafifleyen, daha çok bacaklarda istemsiz hareketler ve paresteziyle karakterize nörolojik bir bozukluktur. Sendromun etiyopatogenezine yönelik çalışmalardan elde edilen bulgular, santral sinir sistemini (SSS) adres göstermektedir. Elektrofizyolojik ve nöroimaj çalışmalarına göre, hareket fizyolojisine katkıda bulunan kortiko-talamo-spinal yollarda, anormallikler tespit edilmiştir. Santral dopaminerjik sistemde disfonksiyon olduğu ve dopaminerjik ilaçlarla semptomların düzeldiği gösterilmiştir. Eldeki kanıtlarla, hastalıktaki santral sirkadiyen faktörlerin etiyopatogenezde önemli rol üstlendiği bilinmesine rağmen, yine de bilinmeyen birçok faktöründe araştırılmasına ihtiyaç vardır. HBS'de oluşan motor ve duyusal semptomların organize edildiği santral yapıların, olaya katılan nöron tiplerinin, aracılık yapan nörotransmitterlerin ve denetleyici santral mekanizmaların daha iyi araştırıldıktan sonra, hastalığın karanlıkta kalan yönlerinin aydınlanacağı açıktır.
The Role of Central Nervous System in the Pathogenesis of Restless Legs Syndrome
Restless legs syndrome is a neurological disorder of the legs characterized by spontaneous movements and paresthesia which appear at rest or sleep and are relieved movements. The studies searching for the ethiopathogenesis of the syndrome showed the role of the central nervous system. According to electrophysiological and neuroimaging studies, abnormalities involving corticothalamospinal tracts which contribute locomotor system physiology have been determined. Recent studies showed dysfunction of the central dopaminergic system and symptoms could he ameliorated by dopaminergic drugs. Although central circadian factors of the disorder were suspected to be responsible for ethiopatho gene sis, most factors remain to be elucidated. Uncertain aspects of the disorder may he explained more definitely after the researches focus on sensory-motor symptoms organized in central structures, participating neuron types, mediating neurotransmitters and central control mechanisms.
