Equivalent linear change in cognition between individuals with bipolar disorder and healthy controls over 5 years

Objectives Cognitive dysfunction is a key feature of bipolar disorder (BD). However, not much is known about its temporal stability, as some studies have demonstrated a neurodegenerative model in BD while others have shown no change in cognitive functioning over time. Building upon our prior work which examined the natural course of executive functioning, the current study aimed to investigate the natural course of memory, emotion processing, and fine motor dexterity over a five year period in BD and healthy control (HC) samples.
