Cognitive Enhancers Consumption: Prevalence, Knowledge, and Determinants of Use Among Medical Students in Egypt, Sudan, and Jordan.

Background: Cognitive Enhancers (CE) are central nervous system stimulant substances known to improve cognitive functions. Due to high-perceived stress and academic pressure, CEs are becoming increasingly popular among medical students. As a result, they are more likely to misuse these substances.

The effects of transcranial direct current stimulation on cognitive function for mild cognitive impairment: a systematic review and meta-analysis of randomized controlled trials.

Background: Transcranial direct current stimulation (tDCS) emerged as a potential modality for enhancing cognitive functions in patients with cognitive decline, including mild cognitive impairment (MCI). Our systematic review and meta-analysis aim to synthesize the available randomized controlled trials (RCTs) on the effects of tDCS on cognitive functions in patients with MCI.

Methods: Our review protocol was registered on PROSPERO with ID: CRD42022360587.
