Cognitive Impairments

This study aims to evaluate the efficacy, safety, and underlying neural mechanisms of TIS targeting the hippocampus in ameliorating cognitive impairment associated with schizophrenia (CIAS). Researchers will compare active TIS to a sham control to see if TIS works to treat CIAS. Participants will receive TIS twice a day for 2 weeks. Their clinical data, including the baseline clinical symptom scale score, cognitive function, E/I imbalance index recorded by EEG, and MRI data, will be collected at baseline, at the end of the 2-week intervention, and 4 weeks after the intervention.

This Phase III trial will examine the efficacy of computerized cognitive training methods on perceived cognitive impairment in breast cancer survivors.

The study aims to address the neurobiological basis of cognitive impairments in chronic cocaine users by investigating the potential impact of an acute potassium channel blockade on working memory performance and other cognitive functions.

This prospective observational study evaluates the association between psychiatric status, GvHD-related symptom severity, and health-related quality of life in patients with graft-versus-host disease. Standardized and validated assessment tools, including the Lee Symptom Scale, will be used to collect psychiatric, clinical, and demographic data.
