How Do Doctors Test for Vascular Dementia?
Published: Dec 14, 2023
Testing for vascular dementia involves various methods to pinpoint the cause of cognitive decline. Early and accurate diagnosis is crucial for effective treatment.
Neuroimaging Techniques
MRI is preferred for detecting signs of small vessel disease, such as microbleeds and white matter changes. These images help identify unrecognized brain injuries that contribute to dementia. For some patients, CT scans may be used due to cost or contraindications.
Cognitive and Neuropsychological Testing
Cognitive tests like the Montreal Cognitive Assessment (MoCA) are used to detect cognitive impairment. Neuropsychological testing further evaluates cognitive function, focusing on executive abilities. These tests help differentiate vascular dementia from other forms of dementia.
The Hachinski Ischemic Score
This score uses medical history and symptoms to assess the likelihood of a vascular component in dementia. A score of 7 or higher indicates a strong vascular contribution. It's a valuable tool for clinicians in diagnosing vascular dementia.
