Alzheimer's disease is the most common cause of progressive decline of cognitive function in aged humans and is characterized by the presence of numerous senile plaques and neurofibrillary tangles accompanied by neuronal loss. The only treatment currently available for the disease is pharmacotherapy with acetylcholinesterase inhibitors, a palliative strategy aimed at the temporary improvement of cognitive function. Other strategies with disease-modifying potential may include the use of antiinflammatory drugs, estrogen replacement therapy and antioxidants. Recent progress in understanding the molecular and cellular pathophysiology of Alzheimer's disease has suggested possible pharmacological interventions that could modify the development and progress of the disease (disease-modifying therapy), such as treatment with secretase inhibitors, transition metal chelators, HMG-CoA reductase inhibitors and amyloid-b immunization. Inhibitors of tau hyperphosphorylation may also modulate the development and progress of the disease.
