Alzheimer’s disease: A Review

Abstract

Alzheimer’s dementia (AD) is increasingly being recognized as one of the most important medical and social problems in older people in industrialized and nonindustrialized nations. To date, only symptomatic treatments exist for this disease, all trying to counterbalance the neurotransmitter disturbance. Three cholinesterase inhibitors (CIs) are currently available and have been approved for the treatment of mild to moderate AD. A further therapeutic option available for moderate to severe AD is memantine, an N-methylD-aspartate receptor noncompetitive antagonist. Treatments capable of stopping or at least effectively modifying the course of AD, referred to as ‘disease-modifying’ drugs, are still under extensive research.
