Dementia is a brain disorder marked by cognitive dys functioning which causes loss of learning , thinking and memory .Various drugs that possess nootropic activity are used for treatment dementia but emerges side effects. To overcome these effects plants with medicinal importance came into existence. India has wide variety (Centella asiatica, Clitoria ternatea ,Ginkgo biloba, Curcuma longa etc)...

Previous studies have shown that crude ginseng extracts enhance performance on shock-motivated tasks. Whether such performance enhancements are due to memory-enhancing (nootropic) properties of ginseng, or to other non-specific effects such as an influence on anxiety has not been determined. In the present study, we evaluated both the nootropic and anxiolytic effects of the ginseng saponin Rb1....

Nootropic drugs used as a memory enhancer can improve thinking, memory, and alertness in people with Alzheimer’s disease and other disease that affect the mind. Memory is perhaps the most vital of all aspects that differentiates human beings from other animals. However, memory can become faulty due to several reasons, and in that case the person is not able to make full use of his or her potent...

Purpose: Migraine headaches and associated symptoms are prevalent medical issues. Medium-chain triglyceride (MCT)/nootropic-based compounds have demonstrated benefits in multiple domains. This study assessed the potential relief provided from a unique, high-concentration MCT/nootropic component blend on migraine frequency, duration, secondary symptoms, quality of life (QOL) during 60-day clinic...

Dementia is a mental disorder characterized by loss of intellectual ability sufficiently severe enough to interfere with one's occupational or social activities. Desmodium gangeticum commonly known as Salparni, is widely used in ayurveda for the treatment of neurological disorders. The present work was designed to assess the potential of aqueous extract of D. gangeticum (DG) as a nootropic agen...

Nootropic agents are proposed to serve as cognition enhancers. The underlying mechanism, however, is largely unknown. The present study was conducted to assess the intracellular signal transduction pathways mediated by the nootropic nefiracetam in the native and mutant Torpedo californica nicotinic acetylcholine (ACh) receptors expressed in Xenopus laevis oocytes. Nefiracetam induced a short-te...

Several 4-substituted 1-acylpiperazines, obtained by molecular simplification of 4-substituted 1,4-diazabicyclo[4.3.0]nonan-9-ones, have been synthesized and tested in vivo on the mouse passive avoidance test, to evaluate their nootropic activity. The results show that, apparently, an N-acylpiperazine group can mimic the 2-pyrrolidinone ring of 1,4-diazabicyclo[4.3.0]nonan-9-one, as the compoun...

The translocator protein (TSPO) promotes the translocation of cholesterol to the inner mitochondrial membrane and mediates steroid formation. In this study, we first report on a biological evaluation of the dipeptide GD-23 (N-carbobenzoxy-L tryptophanyl-L isoleucine amide), a structural analogue of Alpidem, the principal TSPO ligand. We show that GD-23 in a dose range of 0.05 to 0.5 mg/kg (i.p....

Nootropics, natural or synthetic substances that boost brain function and cognitive abilities, were investigated in this study. Specifically, the effects of Zingiber officinale Centella asiatica extracts compared to standard nootropic piracetam. Both plant demonstrated activity contained phytochemicals like flavonoids, tannins, saponins protect from oxidative damage. Sterols such as stigmastero...

The influence of several nootropic drugs (piracetam, pyritinol, meclofenoxat, methylglucamine orotate (MGO) and dihydroergotoxine (DHET) on both the ethanol preference and the enhanced seizure susceptibility after a single dose of ethanol was studied. Piracetam, MGO and DHET reduce the ethanol drinking in ethanol-preferring mice. The enhanced seizure susceptibility after a single dose of ethano...
