Diagnosis of Dementia and Cognitive Impairment

<p>In this special issue of Diagnostics expert contributors have produced up-to-date research studies and reviews on various topics related to the diagnosis of dementia and cognitive impairment. The methods of the assessments discussed extend from simple neurological signs which may be elicited in the clinical encounter through cognitive screening instruments to sophisticated analyses of neuroimaging and cerebrospinal fluid biomarkers of disease. It is hoped that these various methods may facilitate earlier diagnosis of dementia and its subtypes and provide differential diagnosis of depression and functional cognitive disorders as a prelude to meaningful interventions.</p>
