      Alzheimer’s disease (AD) is characterized by dysfunctional intracellular and extracellular biochemical processes that result in neuron death. This article summarizes hypotheses regarding cell dysfunction in AD and discusses the effectiveness of, and problems with, different therapies. Pharmaceutical therapies discussed include cholinesterase inhibitors, memantine, antihypertensive drugs, anti-inflammatory drugs, secretase inhibitors, insulin resistance drugs, etanercept, brain-derived neurotrophic factor, and immunization. Nutritional and botanical therapies included are huperzine A, polyphenols, Ginkgo, Panax ginseng, Withania somnifera, phosphatidylserine, alpha-lipoic acid, omega-3 fatty acids, acetyl L-carnitine, coenzyme Q10, various vitamins and minerals, and melatonin. Stimulatory therapies discussed are physical exercise, cognitive training, music, and socialization. Finally, treatment strategies are discussed in light of the benefits and drawbacks of different therapeutic approaches. It is concluded that potential risks of both approved and non-approved therapies should be weighed against the potential benefits and certain consequences of disease progression. Approaches that target several dysfunctions simultaneously and that emphasize nutritional, botanical, and stimulatory therapies may offer the most benefit at this time.

    Alzheimer disease has a complex etiology composed of nutritional and genetic risk factors and predispositions. Moreover, genetic risk factors for cognitive decline may remain latent pending age-related decline in nutrition, suggesting the potential importance of early nutritional intervention, including preventative approaches. We hypothesized that a combination of multiple nutritional additives may be able to provide neuroprotection. We demonstrate herein that dietary supplementation with a mixture of ALA, ALCAR, GPC, DHA, and PS reduced reactive oxygen species in normal mice by 57% and prevented the increase in reactive oxygen species normally observed in mice lacking murine ApoE when maintained on a vitamin-free, iron-enriched, oxidative-challenge diet. We further demonstrate that supplementation with these agents prevented the marked cognitive decline otherwise observed in normal mice maintained on this challenge diet. These findings add to the growing body of research indicating that key dietary supplementation may delay the progression of age-related cognitive decline.[Abstract]

    Degenerative brain disorders (neurodegeneration) can be frustrating for both conventional and alternative practitioners. A more comprehensive, integrative approach is urgently needed. One emerging focus for intervention is brain energetics. Specifically, mitochondrial insufficiency contributes to the etiopathology of many such disorders. Electron leakages inherent to mitochondrial energetics generate reactive oxygen free radical species that may place the ultimate limit on lifespan. Exogenous toxins, such as mercury and other environmental contaminants, exacerbate mitochondrial electron leakage, hastening their demise and that of their host cells. Studies of the brain in Alzheimer’s and other dementias, Down syndrome, stroke, Parkinson’s disease, multiple sclerosis, amyotrophic lateral sclerosis, Huntington’s disease, Friedreich’s ataxia, aging, and constitutive disorders demonstrate impairments of the mitochondrial citric acid cycle and oxidative phosphorylation (OXPHOS) enzymes. Imaging or metabolic assays frequently reveal energetic insufficiency and depleted energy reserve in brain tissue in situ. Orthomolecular nutrients involved in mitochondrial metabolism provide clinical benefit. Among these are the essential minerals and the B vitamin group; vitamins E and K; and the antioxidant and energetic cofactors alpha-lipoic acid (ALA), ubiquinone (coenzyme Q10; CoQ10), and nicotinamide adenine dinucleotide, reduced (NADH). Recent advances in the area of stem cells and growth factors encourage optimism regarding brain regeneration. The trophic nutrients acetyl L-carnitine (ALCAR), glycerophosphocholine (GPC), and phosphatidylserine (PS) provide mitochondrial support and conserve growth factor receptors; all three improved cognition in double-blind trials. The omega-3 fatty acid docosahexaenoic acid (DHA) is enzymatically combined with GPC and PS to form membrane phospholipids for nerve cell expansion. Practical recommendations are presented for integrating these safe and well-tolerated orthomolecular nutrients into a comprehensive dietary supplementation program for brain vitality and productive lifespan.[Abstract]

    Although many of these compounds have been associated with interesting basic science, none has shown clear clinical benefit to date. Data available for some, such as Ginkgo biloba, curcumin, and huperzine A, suggest that further evaluation is warranted. Familiarity with this literature will allow clinicians to provide meaningful recommendations to patients who wish to use these agents.[Article]

      The effects of galantamine (16 to 24 mg/day) treatment on brain functional activities (blood flow and glucose metabolism) were examined in 18 patients with mild Alzheimer’s disease (AD) in relation to brain acetylcholinesterase (AChE) activity and nicotinic receptors and cognitive function. Our results ultimately suggest that treatment with galantamine has a long-term positive effect on brain perfusion and rCMRglc and stabilizes cognition.[Abstract]

      Twenty-five patients with Alzheimer’s disease (AD) in moderate-severe and severe stages received galantamine in dosage 8 mg daily during the 1st month with the following increasing to 16 mg daily. Six patients received 24 mg per day from the 3rd month. The total duration of therapy was 26 weeks. The therapeutic effects of reminyl and its good tolerability allow to recommend this drug for treatment of severe stages of AD. [Abstract]

      Significantly higher responder rates were observed with galantamine for behaviour (64.9% versus 56.6%; P = 0.024), and numerically favourable responder rates were seen with galantamine for activities of daily living. Treatment-emergent adverse events were generally related with the gastrointestinal system (nausea 20% versus 10%; vomiting 12% versus 5%; galantamine and placebo groups, respectively). Three deaths occurred during double-blind treatment: 2 of 188 subjects receiving galantamine, and 1 of 97 subjects receiving placebo. These findings are consistent with a broad range of cognitive, functional and behavioural benefits with galantamine across the spectrum of AD and AD with CVD.[Abstract]

      Reduction of verbal repetition is a common goal of Alzheimer disease treatment. After 4 months, patients treated with galantamine were more likely to experience a reduction of verbal repetition than those treated with placebo. Diminution of verbal repetition was associated with other improvements, suggesting it might be a clinical marker of a positive treatment response.[Abstract]

      This pilot study was the first to compare the effects of these drugs on sleep in patients or caregivers. Both drugs were safe and well tolerated. Neither galantamine nor donepezil negatively affected sleep; however, on every measure, there were suggestions of slightly more benefit associated with galantamine treatment. Although these results are suggestive of a differential effect of the drugs on sleep, further research is needed to confirm the clinical significance.[Abstract]

A prospective, double-blind, community-controlled comparison of three doses of galantamine in the treatment of mild to moderate Alzheimer’s disease in a Korean population
      In this prospective, multicenter, double-blind, community-controlled, comparative study, patients with mild to moderate AD were randomized to receive galantamine 8, 16, or 24 mg/d; patients were evaluated at baseline (week 0) and after 4, 8, and 16 weeks of treatment. A 4-week dose-titration schedule was used in the 16-and 24-mg/d groups. This study found that galantamine effected significant benefits on the cognitive, functional, and behavioral symptoms of mild to moderate AD in this population of Korean patients. The tolerability results suggest that galantamine is well tolerated in these patients.[Abstract]

      Pooled data from four randomised trials of patients with mild AD indicate that patients who received galantamine 24 mg/day for 6 months improved cognition more often than those who received placebo and that a higher proportion receiving galantamine were globally improved. This suggests that patients with mild AD benefit from galantamine treatment.[Abstract]

      Patients completing two double-blind, placebo-controlled trials (N=699) were escalated to a 24-mg dose (12 mg bid) of galantamine during a period of 2 weeks and treated for 12 months beyond the initial 6.5-month, double-blind period (total treatment duration: 18.5 months). Patients taking galantamine continuously throughout the double-blind and open-label studies (N=288) showed sustained cognitive benefits on ADAS-Cog/11 scores at 18.5 months. Results of this open-label extension support the findings from previous galantamine studies and demonstrate the safety and tolerability of galantamine for up to 18.5 months[Abstract]

      Cognitive decline over 36 months of continuous galantamine treatment was substantially less than the predicted cognitive decline of untreated patients with mild to moderate dementia. Thus, the cognitive benefits of galantamine seemed to be sustained for at least 36 months. These findings suggest that galantamine slows the clinical progression of AD.[Article]

PET imaging of the in vivo brain acetylcholinesterase activity and nicotine binding in galantamine-treated patients with AD
      In conclusion, galantamine caused sustained AChE inhibition for up to 12 months. At the individual level, the in vivo cortical AChE inhibition and (11)C-nicotine binding were associated with changes in the attention domain of cognition rather than episodic memory.[Abstract]

      Since the introduction of the first cholinesterase inhibitor (ChEI) in 1997, most clinicians and probably most patients would consider the cholinergic drugs, donepezil, galantamine and rivastigmine, to be the first line pharmacotherapy for mild to moderate Alzheimer’s disease.The drugs have slightly different pharmacological properties, but they all work by inhibiting the breakdown of acetylcholine, an important neurotransmitter associated with memory, by blocking the enzyme acetylcholinesterase. The three cholinesterase inhibitors are efficacious for mild to moderate Alzheimer’s disease. It is not possible to identify those who will respond to treatment prior to treatment.[Abstract]

      Galantamine’s effect on more severely impaired subjects has not yet been assessed. Nevertheless, this review shows consistent positive effects for galantamine for trials of three to six months’ duration. Although there was not a statistically significant dose-response effect, doses above 8 mg/d were, for the most part, consistently statistically significant. Galantamine’s safety profile in AD is similar to that of other cholinesterase inhibitors with respect to cholinergically mediated gastrointestinal symptoms.[Abstract]

    19. Razay G, Wilcock GK. Expert Rev Neurother. 2008 Jan;8(1):9-17. Galantamine in Alzheimer’s disease
      Galantamine is a cholinesterase inhibitor with a dual mechanism of action. It is a reversible inhibitor of acetylcholine esterase and enhances the intrinsic action of acetylcholine on nicotinic receptors, leading to increased cholinergic neurotransmission in the CNS. Galantamine has a large volume clearance, low plasma protein binding and a high bioavailability. Short-term, double-blind, placebo-controlled studies have shown that treatment with galantamine produces small improvements on cognitive tests and global measures of change in selected patients with mild to moderately severe Alzheimer’s disease. A dose of 16-24 mg/day appears to be the most efficacious, and is the licensed maintenance dose range in most territories. The magnitude of the treatment effect is similar to that of other cholinesterase inhibitors. Adverse events experienced by patients treated with galantamine are usually mild, gastrointestinal and may improve with dose reduction.[Abstract]

      Currently, acetylcholinesterase (AChE) inhibitors are the most promising class of drugs for the treatment of Alzheimer’s disease (AD). Galantamine is a reversible, competitive, tertiary alkaloid AChE inhibitor. The drug is selective for AChE rather than butyrylcholinesterase. In addition to inhibition of AChE galantamine interacts allosterically with nicotinic acetylcholine receptors to potentiate the action of agonists at these receptors. Recipients of galantamine 16 or 24 mg/day achieved significant improvements in cognitive and global symptoms relative to placebo recipients in large (n = 285 to 978 patients with mild to moderate AD) well-designed trials of 3 to 6 months’ duration. Galantamine also improved activities of daily living in these patients and significantly reduced the requirement for caregiver assistance with activities of daily living. Moreover, galantamine recipients achieved significantly better outcomes on behavioural symptoms than placebo recipients. In a long term study (12 months), galantamine 24 mg/day slowed the progression of symptoms of the disease and maintained cognitive function and activities of daily living in patients with mild to moderate AD. Galantamine was generally well tolerated with the majority of adverse events being mild to moderate in intensity and transient. Predictably, adverse events were cholinergic in nature and generally related to the gastrointestinal system.[Abstract]

      Alzheimer’s disease (AD) is linked to cholinergic deficiency and the overactivation of glutamate receptors. The acetylcholinesterase (AChE) inhibition treatment approach has produced the most encouraging results in clinical practice, and memantine, a moderate antagonist of N-methyl-D-aspartate (NMDA) receptors, has been approved for treating AD.

      The naturally occurring alkaloid Huperzine A (HupA) is an acetylcholinesterase (AChE) inhibitor that has been used for centuries as a Chinese folk medicine in the context of its source plant Huperzia Serrata. The potency and relative safety of HupA rendered it a promising drug for the ameliorative treatment of Alzheimer’s disease (AD) vis-à-vis the “cholinergic hypothesis” that attributes the cognitive decrements associated with AD to acetylcholine deficiency in the brain. However, recent evidence supports a neuroprotective role for HupA, suggesting that it could act as more than a mere palliative.[Abstract]

      HupA is a potent, reversible and selective inhibitor of AChE with a rapid absorption and penetration into the brain in animal tests. It exhibits memory-enhancing activities in animal and clinical trials. Compared to tacrine and donepezil, HupA possesses a longer duration of action and higher therapeutic index, and the peripheral cholinergic side effects are minimal at therapeutic doses. Recently, it has been reported that HupA could reduce neuronal cell death caused by glutamate. The dual bio-activities of HupA would further enhance its value and potentiality as the therapeutic agent for Alzheimer s disease.[Abstract]

      Compared to AD patients on placebo, acetyl-L-carnitine-treated patients showed significantly less deterioration in their Mini-Mental Status and Alzheimer’s Disease Assessment Scale test scores. Furthermore, the decrease in phosphomonoester levels observed in both the acetyl-L-carnitine and placebo AD groups at entry was normalized in the acetyl-L-carnitine-treated but not in the placebo-treated patients. Similar normalization of high-energy phosphate levels was observed in the acetyl-L-carnitine-treated but not in the placebo-treated patients. This is the first direct in vivo demonstration of a beneficial effect of a drug on both clinical and CNS neurochemical parameters in AD.[Abstract]

      Neuronal mitochondria are especially vulnerable to oxidative stress due to their role in energy supply and use, causing a cascade of debilitating factors such as the production of giant and/or vulnerable young mitochondrion who’s DNA has been compromised. Therefore, mitochondria specific antioxidants such as acetyl-L-carnitine and R-alphalipoic acid seem to be potential treatments for AD. They target the factors that damage mitochondria and reverse its effect, thus eliminating the imbalance seen in energy production and amyloid beta oxidation and making these antioxidants very powerful alternate strategies for the treatment of AD.[Abstract]

      Recent studies demonstrated efficacy of a vitamin/ nutriceutical formulation (folate, vitamin B12, alpha-tocopherol, S-adenosyl methionine, N-acetyl cysteine, and acetyl-L-carnitine) for mild to moderate Alzheimer’s disease. This formulation holds promise for delaying the decline in cognition, mood, and daily function that accompanies the progression of Alzheimer’s disease, and may be particularly useful as a supplement for pharmacological approaches during later stages of this disorder.[Abstract]

      Neuritic plaques composed mainly of amyloid beta-protein (Abeta) in the brain are an early and invariant neuropathological feature of Alzheimer’s disease (AD). Recently, various compounds such as curcumin, nicotine and wine-related polyphenols have been reported to inhibit the formation, extension of fAbeta, as well as destabilize preformed fAbeta at pH 7.5 at 37 degrees C in vitro. In cell culture experiments, destabilized fAbeta were suggested to be less toxic than intact fAbeta. In transgenic mice model study, some coumpounds such as curcumin and nicotine have also been reported to reduce plaque burden in vivo.[Abstract]

      Alzheimer’s disease (AD) is a neurodegenerative disorder and the most common form of dementia, affecting more than 5.4 million people in the USA. Although the cause of AD is not well understood, the cholinergic, amyloid and tau hypotheses were proposed to explain its development. Drug discovery for AD based on the cholinergic and amyloid theories have not been effective. In this article we summarize tau-based natural products as AD therapeutics from a variety of biological sources, including the anti-amyloid agent curcumin, isolated from turmeric, the microtubule stabilizer paclitaxel, from the Pacific Yew Taxus brevifolia, and the Streptomyces-derived Hsp90 inhibitor, geldanamycin. The overlooked approach of clearing tau aggregation will most likely be the next objective for AD drug discovery.[Article]

Grape seed extract is known as a powerful antioxidant that protects the body from premature aging, disease, and decay. Grape seeds contains mainly phenols such as proanthocyanidins (oligomeric proanthocyanidins). Scientific studies have shown that the antioxidant power of proanthocyanidins is 20 times greater than vitamin E and 50 times greater than vitamin C.[Abstract]
