I am not comprehending things as quickly, and having a hard time committing to memory and then recalling properly.
Taking general chemistry and there is a shit ton of things flying at me quick as it is a summer course. Having a hard time keeping up, and as the class is 6 hours long with a good 4 hours of work at home I just cannot stay sharp all day.
On top of that the calculations mentally wear me out.
I can definitely stay focused and be attentive on my own, I am highly motivated.
Hope that helps.
in that case stimulants may not be the best option for you. However, nicotine with caffeine will get you over the hump and keep you attentive.
For recall and retention i would honestly go with bacopa(it has studies specifically demonstrating this effect) and piracetam at about 1-2 grams per day. for the choline source i see no reason to get fancy, i would simply use lecithin, although cdp-choline has some interesting properties of its own with respect to memory if you want to spend the extra money. those would be a long term couple month supplementation strategy. They will take a while to reach full effect unlike stimulants, but the good thing is you can combine the stims with them in the short term.

Alzheimer's disease is a neurodegenerative disorder characterized by progressive dementia. Bacopa monniera is described in the Ayurvedic Materia Medica, as a therapeutically useful herb for the treatment of cognitive impairment, thus supporting its possible anti-Alzheimer's properties. Our studies have shown that Bacopa monniera reduces beta-amyloid deposits in the brain of an Alzheimer's disease animal model. The objective of this study was to establish the presence of endogenous substances in Bacopa monniera extract (BmE) that will impact components of the oxidative stress cascade such as the reduction of divalent metals, scavenging of reactive oxygen species, alterations of lipoxygenase activity and hydrogen peroxide-induced lipid peroxidation. The extract contained polyphenols and sulfhydryl contents suggestive of endogenous antioxidant activity. The results demonstrated that BmE reduced divalent metals, dose-dependently scavenged reactive oxygen species, decreased the formation of lipid peroxides and inhibited lipoxygenase activity. These data combined with our previous studies that have shown that BmE treatment reduces beta-amyloid levels in the brain of an Alzheimer's disease doubly transgenic mouse model of rapid amyloid deposition (PSAPP mice) suggesting mechanisms of action relevant to the treatment of Alzheimer's disease.

Bacopa monniera is a nerve tonic used extensively in traditional Indian medicinal system "Ayurveda". Reports regarding its various antioxidative, adaptogenic and memory enhancing roles have already appeared in the last few decades. In the present study, aluminium chloride (AlCl(3)) was used to generate neurotoxicity. We have investigated the neuroprotective effect of Bacopa extract against aluminium-induced changes in peroxidative products, such as thio-barbituric acid-reactive substance (TBA-RS) and protein carbonyl contents and superoxide dismutase (SOD) activity. Effect on lipofuscin (age pigments) accumulation and ultrastructural changes were also studied. Bacopa effects were compared with those of l-deprenyl. Co-administration of Bacopa extract during aluminium treatment significantly prevented the aluminium-induced decrease in SOD activity as well as the increased oxidative damage to lipids and proteins. Protective effect was also observed at microscopic level. Fluorescence and electron microscopic studies revealed considerable inhibition of intraneuronal lipofuscin accumulation and necrotic alteration in the CA1 region of the hippocampus. Observations showed that Bacopa's neuroprotective effects were comparable to those of l-deprenyl at both biochemical and microscopic levels.

Cigarette smoking is associated with the development of several diseases and antioxidants play a major role in the prevention of smoking-related diseases. Apoptosis is suggested as a possible contributing factor in the pathogenesis of smoking-induced toxicity. Therefore the present study was designed to investigate the influence of chronic cigarette smoke exposure on apoptosis and the modulatory effect of bacoside A (triterpenoid saponin isolated from the plant Bacopa monniera) on smoking-induced apoptosis in rat brain. Adult male albino rats of Wistar strain were exposed to cigarette smoke and simultaneously administered with bacoside A (10 mg/kg b.w./day, orally) for a period of 12 weeks. Expression of brain hsp70 was analyzed by Western blotting. Apoptosis was identified by DNA fragmentation, terminal deoxynucleotidyl transferase-mediated deoxy uridine triphosphate nick end labeling (TUNEL) staining and transmission electron microscopy. The results showed that exposure to cigarette smoke induced hsp70 expression and apoptosis as characterized by DNA laddering, increased TUNEL-positive cells and ultrastructural apoptotic features in the brain. Administration of bacoside A prevented expression of hsp70 and neuronal apoptosis during cigarette smoking. We speculate that apoptosis may be responsible for the smoking-induced brain damage and bacoside A can protect the brain from the toxic effects of cigarette smoking.
Study to evaluate the effect of a micro (suksma) medicine derived from Brahmi (Herpestris monierra) on students of average intelligence.
J Res Ayurved Siddha. 1993; 14(1-2): 10-24.

A double-blind controlled study was carried out to evaluate the effect of a micro (suksma) medicine derived from Brahmi (Herpestris monniera) by 9 months treatment on 110 boy-students in the age range of 10-13 years and having average IQ (100). Various factors of intelligence were measured before and after treatment. Mean differences in post-testing and pre-testing IQ scores in the experimental group were statistically significant as compared to the control group on the following IQ tests: Memory (Direct) test, Arithmatic test and 4 subtests of Budhimapana test. The result is interesting since in previous studies Ayurvedic medhya rasayanas were not found effective in enhancing intelligence of average students. Long-term studies may prove still more fruitful.
The chronic effects of an extract of Bacopa monniera (Brahmi) on cognitive function in healthy human subjects.
Psychopharmacology (Berl) 2001 Aug;156(4):481-4
Stough C, Lloyd J, Clarke J, Downey LA, Hutchison CW, Rodgers T, Nathan PJ.
RATIONALE: Extracts of Bacopa monniera have been reported to exert cognitive enhancing effects in animals. However, the effects on human cognition are inconclusive.
OBJECTIVE: The current study examined the chronic effects of an extract of B. monniera (Keenmind) on cognitive function in healthy human subjects.
METHODS: The study was a double-blind placebo-controlled independent-group design in which subjects were randomly allocated to one of two treatment conditions, B. monniera (300 mg) or placebo. Neuropsychological testing was conducted pre-(baseline) and at 5 and 12 weeks post drug administration.
RESULTS: B. monniera significantly improved speed of visual information processing measured by the IT task, learning rate and memory consolidation measured by the AVLT (P<0.05), and state anxiety (P<0.001)compared to placebo, with maximal effects evident after 12 weeks.
CONCLUSIONS: These findings suggest that B. monniera may improve higher order cognitive processes that are critically dependent on the input of information from our environment such as learning and memory.
Clinical evaluation of memory enhancing properties of Memory Plus in children with Attention Deficit Hyperactivity Disorder.
Indian Journal of Psychiatry, 2000 Apr; 42(2) Supplement

Memory Plus consists of standardised extract (active constituent identified as Bacosides A & B) from the plant Bacopa monniera, commonly known as Brahmi. Bacosides have undergone extensive pharmacological and toxicity evaluation at Central Drug Research Institute, Lucknow. They facilitate acquisition, consolidation and retention of newly acquired behavioural responses in animal models. The safety and tolerability studies in healthy volunteers have shown them to be safe after single and multiple dose administration. The present study was undertaken to evaluate the memory enhancing properties of Memory Plus in children suffering from Attention Deficit Hyperactivity Disorder (ADHD). In this trial a double blind randomised placebo controlled design was employed. The treatment was assigned to each patient as per random allocation (Memory Plus or placebo). A total of 36 patients were selected as per DSM-IV criteria of ADHD. Of these, 19 patients received Memory Plus (50 mg bd x 12 weeks) and 17 were given placebo. The active drug treatment was followed by a 4 week placebo administration, making the total duration of the trial 16 week in both groups. One patient in the Memory Plus group and 6 in the placebo group dropped out. The mean age was 8.3 years and 9.3 years in Memory Plus and placebo group respectively. The male to female ratio was 5 : 1 in Memory Plus group and 3 : 1 in placebo group. The children were evaluated on a battery of tests (personal information, mental control, sentence repetition, logical memory, word recall (meaningful), digit span test, world recall (non-meaningful), delayed response learning, picture recall and paired associate learning) before (0-day), during drug administration (+4, +8 and +12 weeks) and at the end of the study (+16 weeks). The data analysis has revealed a significant improvement on sentence repetiton, logical memory and paired associate learning following 12 weeks administration of Memory Plus. This improvement was maintained as 16 weeks evaluation conducted after 4 weeks withdrawal of Memory Plus. During the clinical trial Memory Plus has shown excellent tolerability and no drug related adverse effects were reported.
Antioxidant activity of Bacopa monniera in rat frontal cortex, striatum and hippocampus.
Phytother Res 2000 May; 14(3): 174-9
Bhattacharya SK, Bhattacharya A, Kumar A, Ghosal S.
The effect of a standardized extract of Bacopa monniera Linn. was assessed on rat brain frontal cortical, striatal and hippocampal superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPX) activities, following administration for 7, 14 or 21 days. The effects induced by this extract (bacoside A content 82% +/- 0.5%), administered in doses of 5 and 10 mg/kg, orally, were compared with the effects induced by (-) deprenyl (2 mg/kg, p. o.) administered for the same time periods. Bacopa monniera (BM) induced a dose-related increase in SOD, CAT and GPX activities, in all the brain regions investigated, after 14 and 21 days of drug administration. On the contrary, deprenyl induced an increase in SOD, CAT and GPX activities in the frontal cortex and striatum, but not in the hippocampus, after treatment for 14 or 21 days. The results suggest that BM, like deprenyl, exhibits a significant antioxidant effect after subchronic administration which, unlike the latter, extends to the hippocampus as well. The results suggest that the increase in oxidative free radical scavenging activity by BM may explain, at least in part, the cognition- facilitating action of BM, recorded in Ayurvedic texts, and demonstrated experimentally and clinically.
