چکیده
BACKGROUND Selective serotonin reuptake inhibitors improve cognition in patients with stroke and increase the expression of brain-derived neurotrophic factor (BDNF) in the rat hippocampus. However, the effects of selective serotonin reuptake inhibitors on cognition and serum BDNF levels in patients with vascular dementia are largely unknown. We performed an open-label study to investigate the effects of fluoxetine, a selective serotonin reuptake inhibitor, on cognition and serum BDNF levels in patients with vascular dementia. METHODS Fifty patients with vascular dementia were randomly allocated to receive fluoxetine (20 mg/day; n=25) or no fluoxetine (control group; n=25) for 12 weeks. Both groups received secondary prevention of stroke. Serum BDNF level, Mini-Mental State Examination (MMSE) score, Ten-Point Clock Drawing score, and Digit Span Test and Verbal Fluency Test scores were measured at baseline and at week 12 in the both groups. RESULTS The baseline serum BDNF level correlated significantly with the MMSE score. MMSE score, Ten-Point Clock Drawing score, and serum BDNF level increased significantly in the fluoxetine group but not in the control group. The increase in serum BDNF level correlated with the increase in MMSE score in the fluoxetine group. CONCLUSION Fluoxetine may potentially improve cognition in patients with vascular dementia and requires further investigation. BDNF may play an important role in cognitive recovery.

Background and purpose: Post-traumatic stress disorder (PTSD) develops after major trauma that is accompanied by certain signs, including pervasive fear memories, anxiety, abnormality in spatial and cognition memory, and decrease in hippocampal brain-derived neurotrophic factor (BDNF). Selective serotonin reuptake inhibitors (SSRIs) are the first-line treatment for PTSD. This study aimed at inv...

Background and Objectives: Previous studies have indicated that lithium may increase the level of the brain-derived neurotrophic factor (BDNF), which in turn improves the recovery of patients with stroke. In this controlled trial we evaluated the effect of lithium on BDNF serum level in patients with ischemic stroke. Methods: In this randomized controlled...

Background Cryopreservation of ovarian cortex is increasingly used to preserve fertility before cancer therapy. Recently, studies show that Brain-derived neurotrophic factor (BDNF) may be involved in oocyte maturation. Brain-derived neurotrophic factor (BDNF) is member of neurotrophin family that has anti-apoptotic effects on nervous system. Recent researches show that it also plays key role in...
