RESUMEN
Executive impairment is common after stroke, which causes in disabilities for controling thinking, emotion and behavior. The etiology is uncertain. There is no specific assessment tool for it. The psychological assessment is the main approach to screen and diagnose executive impairment, including screening and specific examination. There are still some advantages and disadvantages. The strategy for rehabilitation includes recovery, compulsory and adaptive treatment. Medication is the main treatment, but still unsatisfactory. Cognitive training, computer-assisted cognitive rehabilitation and transcranial direct current stimulation and so on are applied. Imaging and physiological electrical techniques are needed.
RESUMEN
Bipolar disorder (BD) is a chronic mental illness with high recurrence rate and disability. As one of the core symptoms, cognitive impairment may occurs at every stage of the disease. Evidence from the neuroimaging studies revealed that the abnormal brain volumes, the blood flow and oxygen saturation of key brain areas are related to executive impairment in patients with bipolar disorder. This article reviews current structural and functional neuroimaging studies about the executive impairment of patients with euthymic bipolar disorder and research progresses.
RESUMEN
Executive impairment is one of the common sequelae of stroke, which seriously affects the quality of life of patients. Repeti-tive transcranial magnetic stimulation (rTMS), as a new type of electrophysiological technique, has been used in the clinical treatment of Post-Stroke Executive Impairment (PSEI). This paper summarized the survey of PSEI, the basic principle and mechanism of rTMS, clinical application of rTMS for PSEI and its safety. Clinical studies showed that high frequency stimulation, low frequency stimulation, and combi-nation with other therapeutic methods were effective in PSEI. However, there was no unified theory about the mechanism and the best treat-ment plan of rTMS for PSEI.
