Abstract

Some patients with pervasive developmental disorders develop unusual talents, which are characterized as savant syndrome. Herein we present neuropsychological examination and brain imaging (fMRI and brain SPECT) findings of an 18-year-old male with Asperger syndrome and highly unusual calendar memory. Neuropsychological evaluation of the case indicated mild attention, memory, and problem solving deficits, and severe executive function deficits that included conceptualization, category formation, and abstraction. Functional MRI findings showed activation above the baseline level (P < 0.05) in the bilateral inferior parietal lobule, precuneus, superior and middle frontal gyri, and medial frontal cortex. Brain SPECT findings, in comparison to rest-SPECT findings, showed that there was hypoperfusion in some brain regions, including the right frontal cortex and right parietal cortex. Baseline blood perfusion in the left frontal cortex was also observed, as well as hypoperfusion in the right parietal-occipital cortex and in the right basal ganglion (compared to the left side). The results of the present study and further research will contribute to our understanding of calendar memory and savant syndrome.

Özet

Yaygın gelişimsel bozukluğu olan hastalarda izole olarak belli bazı alanlarda normalin üstünde beceriler (savant sendromu) görülebilmektedir. Bu yazıda 18 yaşında olan ve gelişmiş takvim belleği becerisi sergileyen bir Asperger Sendromu olgusunun klinik özellikleri, nöropsikolojik değerlendirme ve beyin görüntüleme çalışmaları (fMRG ve SPECT) bulguları sunulmuştur; nöropsikolojik değerlendirmede hastanın dikkat, bellek ve problem çözme becerilerinde hafif; yürütücü işlevlerinden kavramsallaştırma, kategori oluşturma ve soyut düşünme becerilerinde ileri derecede bozulma tespit edildi. Beyin görüntüleme çalışmalarında fMRG'de bilateral inferior paryetal lobül, prekuneus, superior ve orta frontal girus ve medyal frontal kortekste eşik değerini geçen (p<0.05) aktivasyon ve beyin SPECT değerlendirilmesinde istirahat durumu ile karşılaştırıldığında sağ frontal kortekste, sağ paryetal korteksi de içine alacak şekilde hipoperfüzyonun belirginleştiği görüldü. Sol frontal kortekste bazal kan akımında artış saptandı. Ayrıca, sağ paryeto-oksipital kortekste hipoperfüzyon, sağ bazal ganglionda simetriğine göre, hipoperfüzyon saptandı. Bu bulgular ilgili literatür bilgileri ışığında tartışıldı.
