 Cognitive dysfunction is a common complication in primary or metastatic brain tumors and can be correlated to disease itself or various treatment modalities. The symptoms of cognitive deficits may include problems with memory, attention and information processing. There is a study which suggest that psychological distress is an important factor in reducing health related QOL in patients with brain tumors. However in some studies, depression was found to be another important independent predictor of QOL and has strong impact on survival. QOL is a extensive term that comprises physical or functional status, emotional well-being, and social well-being. It has been studied that QOL in patients with high-grade tumors do not differ those with grade III and grade IV tumors. Compared to patients with non-CNS cancers, brain tumor patients report more fatigue, cognitive dysfunction, and altered mood states. However, different levels of impairments have been observed in patients with brain tumors. To spread awareness of the illness, psychiatric interventions may be useful in these patients. Cognitive dysfunction may affect basic functions including attention or behavior or advanced functions like taking decisions or making plans. According to Yoshii Y et.al, Cognitive dysfunction before or after the surgery may not correlate with stage of tumor malignancy and degree of tumor resection. Cognitive function has been correlated to increased fatigue and depression in newly diagnosed malignant glioma patients.
