To assess the efficacy of the Ginkgo biloba in patients with dementia of the Alzheimer type in slowing down the disease's degenerative progression and the patients' cognitive impairment compared with rivastigmine.
Total 56 patients aged 50-75 years, suffering from dementia, were allocated into one of the two treatments: group 1) Ginkgo biloba (120 mg daily dose); group 2) rivastigmine (4.5 mg daily dose) in a 24-week randomized double blind study. The degree of severity of dementia was assessed by the Seven Minute test and the Mini-Mental State Examination.
Our results confirm the clinical efficacy of rivastigmine in the dementia of the Alzheimer type, comparing to Ginkgo biloba. There are few published trials that have directly compared a cholinesterase inhibitor with Ginkgo for dementia. This study directly compares a cholinesterase inhibitor with Ginkgo biloba for dementia of the Alzheimer type.
Our study suggests that there are differences in the efficacy of Ginkgo biloba and rivastigmine in the treatment of Alzheimer's dementia. In addition, this study suggested that cholinesterase inhibitors should be used in preference to Ginkgo biloba in patients with mild to moderate AD.

    ABSTRACT: With an increase in the number of patients diagnosed with Alzheimer's disease, it is not surprising that there is a consistent increase in use of nutraceuticals and other over-the-counter medications to combat memory complaints and ideally treat dementia. Throughout this review article, the authors highlight recent literature updates on B vitamins, vitamin D, vitamin E, omega-3 fatty acids, and gingko biloba. Similar to any other medication, it is imperative to evaluate the risks and benefits in older patients, especially in light of comorbidities and existing medications.

    ABSTRACT: Alzheimer’s disease (AD) is a neurodegenerative disorder that is characterized by normal memory loss and cognitive impairment in humans. Many drug targets and disease-modulating therapies are available for treatment of AD, but none of these are effective enough in reducing problems associated with recognition and memory. Potential drug targets so far reported for AD are β-secretase, Γ-secretase, amyloid beta (Aβ) and Aβ fibrils, glycogen synthase kinase-3 (GSK-3), acyl-coenzyme A: cholesterol acyl-transferase (ACAT) and acetylcholinesterase (AChE). Herbal remedies (antioxidants) and natural metal-chelators have shown a very significant role in reducing the risk of AD, as well as lowering the effect of Aβ in AD patients. Researchers are working in the direction of antisense and stem cell-based therapies for a cure for AD, which mainly depends on the clearance of misfolded protein deposits — including Aβ, tau, and alpha-synuclein. Computational approaches for inhibitor designing, interaction analysis, principal descriptors and an absorption, distribution, metabolism, excretion and toxicity (ADMET) study could speed up the process of drug development with higher efficacy and less chance of failure. This paper reviews the known drugs, drug targets, and existing and future therapies for the treatment of AD.

    ABSTRACT: An estimated five million people age 65 and older suffer from Alzheimer’s disease and approximately 200,000 individuals under age 65 have younger-onset Alzheimer’s. For persons with Alzheimer’s disease and other dementias, in addition to the devastating impact upon health and quality of life, the aggregate costs for healthcare, long-term care and hospice are projected to increase from $203 billion in 2013 to $1.2 trillion in 2050. These statistics are staggering when coupled with the fact that there are no curative medications currently available. The goal of this chapter is to review the current and promising pharmacologic approaches to managing various aspects of Alzheimer’s disease, namely the cognitive, functional and behavioral.
