[Neuroimaging for the diagnosis of dementia.].

Development of laboratory diagnosis and neuroimaging revealed some biomarkers for in vivo diagnosis of the most common forms of dementia (Alzheimer's disease, Lewy body dementia and vascular dementia) for their differential diagnosis. Structural changes found using magnetic resonance imaging (MRI) are significant for the prognosis of the cognitive decline. Cerebral microbleeds are an available adjuvant diagnostic marker, which increases the diagnostic value of leukoaraiosis that suggests the development of cerebral amyloid angiopathy or hypertensive microangiopathy, especially in cases of mixed causes of dementia and severe cognitive deficits.
