Overview
A MRI is commonly performed, although this modality (as is noted below) may not have optimal sensitivity for the diffuse metabolic changes associated with dementia in a patient who shows no gross neurological problems (such as paralysis or weakness) on neurological exam. MRI may suggest normal pressure hydrocephalus, a potentially reversible cause of dementia, and can yield information relevant to other types of dementia, such as infarction (stroke) that would point at a vascular type of dementia.
Asymmetric cortical atrophy is often observed in neurodegenerative dementias and sometimes manifests as disproportionate impairments in the functions mediated by the more atrophic regions.
