* While smoking has been associated with many negative consequences to human health, one possible benefit is that nicotine could improve cognitive functions. Previous studies have suggested that smoking may influence brain-derived neurotrophic factor (BDNF) levels.

* Our research revealed that tobacco product use led to an increase in working memory and human plasma BDNF levels. Furthermore, nicotine was responsible for the elevation in BDNF levels, which showed dose-dependent increases in both serum and the hippocampus, and improved memory performance.

* Animal study (rat)

*Conclusions: "A review of the literature indicates that a significant disruption of cholinergic neurotransmission might be a central issue for both LC/ME/CFS and PVS. The hypothesis of a viral blockade of nAChRs and the possibility of a competitive reversal of this blockade by LDTN has been corroborated by highly promising results in the broad application of this method to numerous patients. Randomized controlled trials are necessary to determine whether these preliminary results can be substantiated by evidence. However, LDTN application provides many patients with a method that offers a high probability of symptom relief with only minor side effects and represents an affordable therapeutic intervention for the majority of people affected worldwide. Furthermore, dose-finding studies are required to develop individually adapted therapy regimens with regard to dosage and duration of therapy."
