piracetam
phenibut
bacopa monnieri

to sa pelne nazwy... opisy masz w google...

to se poszukam dzieki

bralem zarówno
Cerebro Syntrax jak i Psychotropin Ergopharm (wy***any sklad swoja drogo)
ale to bardzo nie ekonomiczna zabawa.
w moim przypadku
4 kaps cerebro
6-8 kaps Psychotropin
i zaczynalem czuc efekt

testowalem neurospeeda na kilku osobach i moge z czystym sumieniem napisac ze dziala ( no moze z nie do konca czystym bo nie na sobie )

kazam!
W bazie prac naukowych PubMeb nie widać ani jednego badania naukowego z grupą kontrolną placebo, które by wykazało, że Ginkgo Biloba ma jakikolwiek wpływ na pracę umysłową (prac, które wykazały coś odwrotnego, tj. zerową skuteczność, jest sporo).

no faktycznie jestes takim autorytetem ze wierze ci na slowo...

This study investigated the effects of acute doses of Ginkgo biloba extract (GBE) on memory and psychomotor performance in a randomized, double-blind and placebo controlled 5-way cross-over design. Thirty-one volunteers aged 30-59 years received GBE 150 mg (50 mg t. d.s), GBE 300 mg (100 mg t.d.s.), GBE 120 mg mane and GBE 240 mg mane and placebo for 2 days. Following baseline measures, the medication was administered at 0900 h for the single doses and at 0900, 1500 and 2100 h for the multiple doses. The psychometric test battery was administered pre-dose (0830 h) and then at frequent intervals until 11 h post dose. The results confirm that the effects of GBE extract on aspects of cognition in asymptomatic volunteers are more pronounced for memory, particularly working memory. They also show that these effects may be dose dependent though not in a linear dose related manner, and that GBE 120 mg produces the most evident effects of the doses examined. Additionally, the results suggest that the cognitive enhancing effects of GBE are more likely to be apparent in individuals aged 50-59 years. Copyright 1999 John Wiley & Sons, Ltd.

The effects of capsules containing 60 mg of a standardised extract of Ginkgo biloba (GK501) and 100 mg of a standardised extract of Panax ginseng (G115) on various aspects of cognitive function were assessed in healthy middle-aged volunteers. A double blind, placebo controlled, 14 week, parallel group, repeated assessment, multi-centre trial of two dosing regimens, 160 mg b.i.d. and 320 mg o.d. was conducted. Two hundred and fifty-six healthy middle-aged volunteers successfully completed the study. On various study days (weeks 0, 4, 8, 12 and 14) the volunteers performed a selection of tests of attention and memory from the Cognitive Drug Research computerised cognitive assessment system prior to morning dosing and again, at 1, 3 and 6 h later. The volunteers also completed questionnaires about mood states, quality of life and sleep quality. The Ginkgo/ginseng combination was found significantly to improve an Index of Memory Quality, supporting a previous finding with the compound. This effect represented an average improvement of 7.5% and reflected improvements to a number of different aspects of memory, including working and long-term memory. This enhancement to memory was seen throughout the 12-week dosing period and also after a 2-week washout. This represents the first substantial demonstration of improvements to the memory of healthy middle-aged volunteers produced by a phytopharmaceutical.




Neuropsychological changes after 30-day Ginkgo biloba administration in healthy participants.

Ginkgo biloba extract (EGb) from the world's oldest living tree has been reputed to ameliorate cognitive decline in the elderly and slow cognitive deterioration in patients with dementia of the Alzheimer's type. EGb remains as one of the most popular plant extracts to alleviate symptoms associated with a range of cognitive disorders such as Alzheimer's disease, vascular dementia and age-related amnesic conditions. EGb is known to contain a range of chemically active components that have antagonistic effects on platelet-activating factor, free-radical scavenging activity and direct effects on the cholinergic neurotransmitter system. Recently there has been much speculation, that EGb may act as a 'smart drug' or nootropic agent in the healthy young to improve intelligence. We conducted a 30-d randomized, double-blind, placebo-controlled clinical trial in which 61 participants were administered a battery of validated neuropsychological tests before and after treatment. Statistical analysis indicated significant improvements in speed of information processing working memory and executive processing attributable to the EGb.

[Effect of Ginkgo biloba extract on memory deficits in radial maze performance induced by some drugs in rats]

Ginkgo biloba extract is widely used as a herbal medicine or dietary supplement in Europe, since Ginkgo biloba extract is effective in facilitation of learning and recollection of memories. However, little is known about the mechanism of the action of Ginkgo biloba extract on learning and memory enhancements. On the other hand, it is well known that cholinergic, histaminergic and glutamatergic systems play a crucial role in learning and memory in animals. Therefore, in order to elucidate the mechanism of Ginkgo biloba extract on memory, we studied and clarified the effect of Ginkgo biloba extract on spatial memory deficits induced by scopolamine, diphenhydramine or MK-801 using eight-arm radial maze performance. It was found that Ginkgo biloba extract improved the spatial memory deficits induced by scopolamine. Ginkgo biloba extract also caused repair to spatial memory deficits induced by diphenhydramine. On the other hand, no significant effect was observed with MK-801-induced spatial memory deficits. These findings suggest that the effect of Ginkgo biloba extract is mediated not only by the cholinergic system but also by the histaminergic system to induce learning and memory enhancements.

The Ginkgo biloba extract EGb 761 increases viability of hnt human neurons in culture and affectsthe expression of genes implicated in the stress response.

There are numerous studies describing the neuroprotective effects of Ginkgo biloba extract EGb 761 on patients with disturbances of vigilance, memory and cognitive functions associated with aging and senility. Describing the pattern of gene expression in EGb 761-treated human hNT neurons may elucidate the molecular pathways leading to the neuroprotection. We used cDNA macroarrays including genes implicated in the antioxidant and stress responses to define the transcriptional effects of EGb 761 (250 microg/ml, 24 hr) on human hNT neurons. Seven genes were identified whose expression was strongly modified by the EGb 761 treatment. Three groups are distinguished: genes encoding transcription factors (increase of NF-kappaB p65 subunit and zinc finger protein 91 mRNAs, and decrease of c-myc transcripts), genes involved in antioxidant defenses (increase of the CuZn SOD mRNAs, and decrease of glutathione reductase and glutathione S-transferase pi mRNAs) and genes involved in stress responses (up-regulation of HSP70 transcripts). Consistent with the modulation of mRNAs by EGb 761, the enzymatic activities of glutathione reductase and glutathione S-transferase were decreased. Surprisingly, CuZn SOD activity was decreased despite increased abundance of the mRNAs; furthermore MnSOD activity was unmodified, and thus the effect of EGb 761 was specific to CuZn SOD. These results support the idea that modulation of target genes and transcription factors may be involved in the neuroprotective action of EGb 761.
