Abstract
Dementias constitute a heterogeneous group of affections and morphological imaging is routinely requested in case of detection of any recent dementia. In the clinical practice, screening imaging examinations such as brain CT and MRI are useful to exclude secondary dementia from neurodegenerative disorders. This morphological imaging help guiding the second-line diagnostic process: oriented biology, functional and metabolic imaging. Through an iconographic review, we will try to explain the value of CT and MRI exams and to propose a simplified MRI protocol. Our paper will simplify the classification of dementias and explain the value of morphological brain imaging in dementia while differentiating neurodegenerative from secondary causes of dementia related to brain tumors, subdural hematomas, normal pressure hydrocephalus, cerebrovascular, inflammatory, infectious, nutritional, metabolic and toxic disorders.
