Progress in Alzheimer's disease research in the last year.

Alzheimer's disease (AD) is the most common cause of dementia in the elderly, with a prevalence of 5 % after 65 years of age, increasing to about 30 % in people aged 85 years or older. It is characterized by progressive cognitive impairment, including impaired judgment, decision-making and orientation, and in some cases accompanied by psycho behavioral disturbances or language impairment. Herein, we summarize and discuss the main articles describing novel findings in AD published over the last year, including clinical, therapeutic, and research issues.
