Statement of IntentThese guidelines are not intended to serve as a standard of medical care. Standards of medical care are determined on the basis of all clinical data available for an individual case and are subject to change as scientific knowledge advances and patterns of care evolve.The contents of this publication are guidelines to clinical practice, based on the best available evidence at the time of development. Adherence to these guidelines may not ensure a successful outcome in every case. These guidelines should neither be construed as including all proper methods of care, nor exclude other acceptable methods of care. Each physician is ultimately responsible for the management of his/her unique patient, in the light of the clinical data presented by the patient and the diagnostic and treatment options available.
ForewordDementia represents a major public health concern in Singapore and worldwide. Being the most prevalent neurodegenerative disease, dementia is expected to affect 55,000 patients in Singapore by the year 2020. The commonest cause of dementia is Alzheimer's disease with vascular dementia being the next most important cause. Right from the stage of mild dementia up to the stages of severe dementia, this condition poses a significant health and socio-economic burden to patients, caregivers and the nation as a whole. Early diagnosis will allow appropriate use of pharmacological and non-pharmacological management. Along with disease stabilization, efforts to address caregiver burden, patient safety and medico legal concerns should form the principles of management. Clear practise guidelines will allow holistic and optimal care in dementia.I am pleased to present the revised clinical practise guidelines for dementia. In this regard the workgroup has performed a thorough review of the existing literature to recommend both pharmacological and nonpharmacological aspects of management for patients ranging from mild cognitive impairment to severe dementia. This revised guidelines also highlights issues related to the management of mild cognitive impairment, young onset dementia and e...
