The number of people with dementia is escalating globally. About 47 million people were living with dementia in 2015 worldwide.1 Dementia is a chronic disease and patients need to live with cognitive impairment for a substantial period of time, which in turn causes a lot of distress and difficulties to patients, their families and society. However, the effectiveness of anti-dementia drugs, namely cholinesterase inhibitors and memantine, in preventing cognitive decline is limited. Some patients may not tolerate the side effects of anti-dementia drugs. Non-pharmacological approaches, such as cognitive intervention and brain stimulation methods, are used. This article would present an overview of these approaches.
