Abstract

Background: Soft neurological signs (SNS) are found to be in excess in bipolar disorder (BD). This paper explores changes in SNS with ageing to ascertain whether BD is associated with a progressive neurological decline or a relatively fixed, persistent deficit. Methods: 53 euthymic BD subjects and controls, aged 15-55 years, were for examined for the presence of SNS which were rated using a modified Kolakowska battery. Results: In controls, SNS scores increased slowly and significantly with age whereas in BD subjects high scores occurred throughout the age range and were not age dependent. This confirms and extends an earlier, smaller, study which is reanalysed. Limitations: The study design was cross-sectional whereas a longitudinal study would better reveal changes in soft signs with ageing. Conclusions: The studies suggest strongly that BD is accompanied by a significant neurobiological deficit which may progress only minimally with increasing age. © 2007.
