Beyin Damar Hastalığı Sonrası Gelişen Frontal Belirtiler ve Klüver-Bucy Benzeri Sendrom
H Özdemir, M Rezaki
Hacettepe Ü. Tıp Fak. Psikiyatri ABD, Ankara
Subaraknoid kanama ve hidrosefali sonrası frontal lob belirtileri ve Klüver-Bucy benzeri sendrom gelişen bir vaka sunulmaktadır. Klüver-Bucy Sendromu nadiren görülen sakinlik, görme agnozisi, hiperseksüalite, hiperoralite ve hipermetamorfoz (her görsel uyarana tepki verme veya dokunmaya çalışma eğilimi) ile kendini gösteren nörodavranışsal bir durumdur. Sıklıkla amigdala ve ilişkili yollardaki hasar ile ortaya çıkan bir sendromdur. Sendrom kafa travması, anoksik-iskemik ensefalopati, herpes simpleks ensefaliti ve Reye Sendromu sonrası görülmektedir. Bilateral orta serebral arter anevrizma ameliyatına bağlı menenjit sonrası hidrosefali gelişen 45 yaşındaki sağ elini kullanan kadın hasta bir takım davranışsal ve duygusal değişikliler nedeniyle psikiyatri polikliniğine başvurmuştur. Psikiyatrik değerlendirmede artmış ve disinhibe konuşma, perseverasyon, sakinlik, bozulmuş yap/yapma testi, çok yeme gibi özellikler saptanmıştır. Beyin manyetik rezonans görüntülemede her iki anterior superior temporal loblarda (amigdalayı da içine alan) ensefalomalazik–gliotik değişiklikler, hidrosefali, frontal bölgede beyaz cevherde iki taraflı sinyal değişiklikleri ve bilateral sentrum semiovalede enfarkt alanı olduğu rapor edilmiştir. Sakinlik (azalmış korku ve öfke tepkileri) ve yeme alışkanlığında değişme Klüver-Bucy Sendromunun özellikleri arasındadır. Disinhibisyon ve perseverasyon ise frontal lob işlev bozukluğuna işaret etmektedir.
Klüver-Bucy-Like Syndrome and Frontal Symptoms Following Cerebrovascular Disease
We present a case with frontal lobe symptoms and Klüver-Bucy-like syndrome following subarachnoid hemorrhage and hydrocephaly. Klüver-Bucy syndrome is a rare neurobehavioral condition characterized by placidity, visual agnosia, hypersexuality, hyperorality, and hypermetamorphosis (the tendency to react to or to touch every visual stimulus). The syndrome is usually associated with lesions of the amygdala or its pathways, and it occurs after head trauma, anoxia-ischemic encephalopathy, herpes simplex encephalitis, and Reye ’s syndrome. A 45- [year]–old right-handed female patient, who developed hydrocephaly after meningitis due to bilateral middle cerebral artery aneurysm surgery presented to our psychiatry clinic with various behavioral and emotional changes. In her psychiatric examination, increased and disinhibited speech, perseveration, placidity, impaired go/no go task performance, and hyperphagia were observed. The patient was treated with risperidone 0.5 mg/day. Magnetic resonance imaging (MRI) of the brain showed encephalomalacic-gliotic changes in the anterior superior medial temporal lobe (including bilateral amygdala), hydrocephalus, bilateral abnormal signal intensity in the white matter of the frontal region, and bilateral infarction in the centrum semiovale. Symptoms, such as placidity (loss of anger and fear) and altered dietary habits are some of the clinical features of Klüver-Bucy syndrome, whereas disinhibition and perseveration are associated with prefrontal cortex dysfunction.
