Alzheimer's disease (AD) is the most prevalent neurodegenerative disorder with approximately 29 million aging people suffering from this disease worldwide. This number is projected to become triple by 2050. AD is a complex and multifactorial neurodegenerative condition, characterized by complex pathology including oxidative stress, formation of aggregates of amyloid and tau, enhanced immune responses, metal deposition and disturbances in cholinesterase enzymes. There is no effective pharmacological treatment for combating the disease till date. The ineffectiveness of current pharmacological interventions in AD has led scientists to search for more safe and effective alternative therapeutic agents. Thus, natural products have become an important avenue for drug discovery in AD research. In this connection, polyphenols are natural products that have been shown to be effective in the modulation of the type of neurodegenerative changes seen in AD, suggesting a possible therapeutic role. The present review focuses on the chemistry of polyphenols, clinical studies for evaluating polyphenols as effective alternatives in AD treatment, cellular and molecular aspects of polyphenols in improving cognitive deficits and the current challenges and futuristic approaches to use polyphenols as safe and effective therapeutic agents in AD treatment.

Review of the medical necessity of hospital or other health facility admissions, upon or within a short time following an admission, and periodic review of services provided during the course of treatment.
Formal programs for assessing drug prescription against some standard. Drug utilization review may consider clinical appropriateness, cost effectiveness, and, in some cases, outcomes. Review is usually retrospective, but some analysis may be done before drugs are dispensed (as in computer systems which advise physicians when prescriptions are entered). Drug utilization review is mandated for Medicaid programs beginning in 1993.
Abnormal structures located chiefly in distal dendrites and, along with NEUROFIBRILLARY TANGLES and SENILE PLAQUES, constitute the three morphological hallmarks of ALZHEIMER DISEASE. Neuropil threads are made up of straight and paired helical filaments which consist of abnormally phosphorylated microtubule-associated tau proteins. It has been suggested that the threads have a major role in the cognitive impairment seen in Alzheimer disease.

Of all the types of Dementia, Alzheimer's disease is the most common, affecting around 465,000 people in the UK. Neurons in the brain die, becuase 'plaques' and 'tangles' (mis-folded proteins) form in the brain. People with Al...
