Abstract

Objective: Although many studies have found a negative effect of lithium (Li) on the motor system in bipolar disorder, there is a lack of evidence about the effects of valproate (VP) on motor and sensory speed. We aimed to compare the effects of Li and VP on motor and sensory speed in medication-free bipolar patients (MF) and healthy controls (HCs). Methods: Euthymic patients with bipolar disorder according to the DSM-IV on Li monotherapy (n=22), VP monotherapy (n=21), MF (n=18) and HCs (n=37) were enrolled. The finger-tapping test, Pegboard Test, visual and auditory reaction time tests, Montreal Cognitive Assessment and Edinburgh Handedness Inventory were the measures. Results: The Li group was significantly slower than the HC and MF groups in the right hand trial of the Pegboard Test. The Li group scored significantly lower in the right and left hand trials of the finger-tapping test in comparison to the HC and MF groups. All patient groups (MF, Li and VP) had slower visual reaction time scores than the HC group. The Li and VP groups had significantly slower auditory reaction time scores than the HC group. Conclusion: Lithium may impair sensory and motor speed more than VP. Medication-free patients differed from healthy controls only in the visual reaction time test. Lithium may disturb movement systems by affecting the complex integration of the brain structures serving motor coordination. These results may also suggest that in the euthymic phase of bipolar disorder, disturbance of psychomotor functions may be related to medications.

Özet

Amaç: Birçok çalışma lityumun (Li) motor sistemi olumsuz etkilediğini göstermiştir, fakat henüz bipolar bozuklukta valproatın (VP) motor ve sensör hıza olan etkileriyle ilgili yeterli kanıt bulunmamaktadır. Bu çalışmada Li ve VP’nin motor ve sensör hıza olan etkilerinin ilaç kullanmayan hastalar (İKH) ve sağlıklı kontrollerle (SK) karşılaştırarak incelenmesi amaçlanmıştır. Yöntemler: DSM-IV’e göre bipolar bozukluğu olan ötimik 22 Li kullanan, 21 VP kullanan, 18 İKH ve 37 SK katılımcı çalışmaya alındı. Parmak-tıklama testi, çivi tahtası testi, görsel ve işitsel tepki süresi testi, Montreal Bilişsel Değerlendirme Testi ve Edinburgh El Tercihi Envanteri kullanılan ölçüm aygıtlarıydı. Bulgular: Gruplar arasında çivi tahtası testinin sağ el denemesinde Li grubu SK ve İKH gruplarından, VP grubu SK grubundan daha yavaş bulundu. Parmak- tıklama testinin sağ ve sol el denemelerinde Li grubu SK ve İKH gruplarından yavaş bulundu. Görsel tepki süresi testinde tüm hasta grupları (Li, VP ve İKH) SK grubundan daha uzun ortalama tepki süresi gösterdiler. İşitsel tepki süresi testinde Li ve VP gruplarında SK’lara göre anlamlı derecede uzun tepki süresi saptandı. Sonuç: Lityum sensör ve motor hızı valproata göre daha olumsuz etkileyebilir. İlaç kullanmayan hastaların, sağlıklı kontrollere kıyasla yalnız görsel tepki süresinde uzama tespit edildi. Lityum motor koordinasyonu sağlayan beyin yapılarının karmaşık entegrasyonunu etkileyerek hareket sistemini etkiliyor olabilir. Ayrıca bu sonuçlar bipolar bozukluğun ötimik döneminde ortaya çıkabilecek psikomotor işlevlerdeki sorunların tedavilerle ilişkili olabileceğini önermektedir.
