A Retrospect in Study of Relationships Between Anxiety, Depression and Working Memory Capacity

Abstract

Working Memory Capacity (WMC) is a crucial component in the study of cognitive functions such as learning, problem-solving, and decision-making. Recent research has illuminated the neurobiological foundations of WMC and its connection to academic success, particularly in children. In addition, research into individual differences throughout a persons life has uncovered connections between visual short-term memory, working memory and mathematical proficiency. Depression, marked by emotional distress and neurological degradation, and anxiety, typified by elevated discomfort and physiological arousal, often coincide. It is important to note that these disorders have high comorbidity rates, impacting almost 90% of those with anxiety and 85% of those with depression. Understanding this comorbidity is crucial due to its significant social impact. Existing research demonstrates that depression and anxiety have separate effects on WMC. Therefore, it is essential to grasp the intricacies of depression and anxiety in context of the comorbidity, considering their adverse social impact. Depression compromises working memory, especially in situations involving emotionally-charged data, while anxiety directs cognitive resources away from tasks requiring WMC by causing deficits in attentional control. Comorbidity exacerbates these deficits and appears to be linked with impairments in inhibitory control.Future research must focus on mechanistic insights, exploring the neural basis and therapeutic interventions for this intricate interplay.In conclusion, there is potential for enhancing cognitive function and mental health interventions through comprehending the interplay between WMC, anxiety, and depression. These results underline the necessity of holistic approaches to tackle the cognitive functioning consequences of mental health issues.
