Amaç: Araştırma geç başlangıçlı (GB) ve erken başlangıçlı (EB) olarak iki gruba ayrılan alkol bağımlılarının nöropsikolojik işlevlerindeki bozukluklarının saptanması amacıyla gerçekleştirilmiştir. Bu şekilde, iki grup arasındaki olası ayırt edici özelliklerin elde edilmesi hedeflenmiştir.

Yöntem: Ondördü erken başlangıçlı, 20’si ise geç başlangıçlı olmak üzere toplam 34 alkol bağımlısı hasta ve sağlıklı gönüllülerden oluşan 11 kişilik kontrol grubu araştırmaya dahil edilmiştir. Erken başlangıç ölçütü olarak 20 yaş sınır kabul edilmiştir. Hasta grubu yatarak alkolden arındırma (detoksifikasyon) tedavisine alınmış ve bu tedavinin hemen sonunda, herhangi bir ilaç kullanmazken nöropsikolojik becerilerini saptamaya yönelik olarak Wisconsin Kart Eşleme (WKET), Sözel Akıcılık (SAT) ve Wechsler Bellek Testleri (WBT) uygulanmıştır. Kontrol grubunu oluşturan denekler için de aynı işlemler gerçekleştirilmiştir.

Bulgular: Kontrol grubu ile karşılaştırıldığında her iki alkol bağımlılığı grubunda Wisconsin Kart Eşleme (WKET) ve Wechsler Bellek Testlerinde (WBT) benzer bir bozukluk profili kaydedilmiştir. Nöropsikolojik testlerdeki başarıları bakımından alkol bağımlılığı grupları arasında bir farklılık saptanmamıştır.

Sonuç: Erken başlangıçlı alkol bağımlılığı grubu bilişsel işlevlerindeki bozukluk bulguları bakımından geç başlangıçlı alkol bağımlılığı grubundan farklı değildir. Frontal bölge ile ilgili beceriler her iki grupta da bozulmuştur. Her iki grupta da bellek alanında bozukluklar ortaya çıkmaktadır. Bu bulgular tipolojik olarak erken/geç başlangıçlı alkolizm ayırımının bu araştırmada değerlendirilen nöropsikolojik beceriler bakımından desteklenmediğini göstermektedir.
Neuropsychological Functions in Early and Late Onset Alcoholism
Objective: To compare late and early onset alcoholism with regard to neurocognitive functions
Method: Using the age of alcoholism onset as a criterion, 20 late onset and 14 early onset male alcoholics were included in the study. Eleven healthy male volunteers with similar demographic features were included as a control group. Alcohol and drug modules of Schedules for clinical Assessment in Neuropsychiatry (SCAN) were administered to each subject in order to gather data on alcohol intake variables. The life time severity of drinking problems was assessed by the Michigan Alcoholism Screening Test (MAST) All patients met the diagnostic criteria of ICD-10 for alcohol dependence. The neuropsychological battery consisted of the Wisconsin Card Sorting Test, the Wechsler Memory Scale and Word Fluency Tests. The battery was administered to each patient 15 days after their entry into detoxification programme when the withdrawal syndrome ceased and all the psychotropic medications stopped for at least 1 week.

Results: Compared with the control group, both groups of alcoholic patients displayed impairment in frontal lobe functions and memory. Neuropsychological test performance did not differ between early and late onset groups.

Conclusions: The results of this study suggest that subtypes of alcoholism based on a one-dimensional clinical application of Cloninger’s typology are not associated with discriminatively different patterns of neuropsychological abnormalities.
