Summary: The search for reliable biomarkers of schizophrenia is important and should involve assessing multiple biomarkers simultaneously. Investigating biomarkers in individuals with schizophrenia-related traits in the general population can accelerate progress in understanding the mechanisms of schizophrenia. There is a lack of research on certain types of memory biomarkers in schizotypy, which presents an opportunity for researchers to address gaps in knowledge and potentially uncover new insights.

Summary: This study examined whether mindset of intelligence leads to placebo effects in working memory training, and found no significant difference between groups in both working memory capacity and fluid intelligence tasks during the 1-hour training session.

Summary: The study found that patients with schizophrenia exhibit thalamic hyperconnectivity with sensorimotor cortices and hypoconnectivity with prefrontal-cerebellar regions during both rest and task engagement, which is related to working memory performance.

Summary: This study found significantly higher levels of overnight norepinephrine in patients with schizophrenia, along with reduced working memory performance, compared to healthy controls. There was a significant negative correlation between norepinephrine and working memory in patients, independent of age, sex, and medication. These results suggest a potential peripheral impact of norepinephrine on working memory in schizophrenia that warrants further investigation.

Summary: Intelligence is strongly linked to working memory, and working memory training can enhance fluid intelligence by improving inhibitory control. This study investigated the role of inhibitory control in working memory training from an electrophysiological perspective. The results showed that working memory training significantly improved the fluid intelligence of children and enhanced their response inhibition ability.

Summary: The neuropsychological profile of Indian DMD subjects is not well understood and requires evaluation. Results show poor verbal and visual memory profiles in DMD patients, with working memory deficits being a crucial element of cognitive functioning. Working memory interventions may help improve neuropsychological profiles in DMD cases.

Summary: Utilizing fNIRS technology, this study investigated the hemodynamic activity during a working memory task in schizophrenia patients, revealing alterations in the right frontopolar cortex possibly linked to working memory deficits. Furthermore, olanzapine equivalent doses were found to be correlated with brain activity and performance in working memory tasks.

Summary: This study found that early encoding of a single item is intact in patients with a schizophrenia spectrum disorder, but information rapidly decays from working memory stores with extended delays. Accuracy further decreases when information is retrieved from working memory, suggesting that working memory stores may also be susceptible to disruption from internal stimuli.

Summary: This study examined different models of working memory in 170 Japanese school children and found that a model distinguishing between verbal and spatial memory fit the data well. The study also found that working memory explained a significant portion of the variance in fluid intelligence, with verbal and spatial memory independently explaining a residual portion. In terms of crystallized intelligence, verbal memory explained the largest portion of the variance, with the joint contribution of verbal and spatial memory explaining the remaining part.

Summary: This study observed first-episode drug-naive schizophrenia patients and found deficits in working memory capacity in both behavioral and electrophysiological measures. Additionally, the increased parieto-occipital pre-encoding stimulus alpha power was associated with symptom severity in schizophrenia. The lack of load effect in neural activities may serve as a potential mechanism for impaired selective attention and working memory in schizophrenia.

Summary: The search for a cortical signature of intelligent behavior has led to a focus on the frontoparietal network (FPN) and the correlation between intelligence and activity in this cortical circuit. In this study, alpha event-related spectral perturbation (ERSP) was used to indirectly measure cortical activity during mental rotation tasks. The results suggest that frontal alpha ERSP is correlated with working memory score in mental rotation tasks.

Summary: This study reviews recent research from both behavioral and neuroimaging perspectives to summarize the working memory deficits of children with schizophrenia and discusses pathogenic factors such as genetic susceptibility. Additionally, this study proposes practical interventions to improve cognitive symptoms of schizophrenia from psychological and neural perspectives.

Summary: This study aimed to improve visual-spatial working memory (vsWM) in treatment-resistant schizophrenia (TRS) through intermittent theta burst stimulation (iTBS) targeting the left dorsolateral prefrontal cortex. The results showed significant improvement in vsWM accuracy after 2 weeks of iTBS treatment, with a positive correlation between improvements and activity in the right visual cortex.
