Which imaging techniques are regularly indicated for patients with suspicion of dementia?


Imaging techniques are mainly used to provide a proof of diagnosis, to exclude secondary dementia and to detect possible vascular damage. The guidelines of the specialists DGNPPN/DGN (D), NICE-SCIE (UK) and EFNS-ENS (EU) recommend the regular use of imaging techniques for patients with suspected dementia. Guidelines focusing on the general practitioner’s setting, DEGAM (D), CCCDTD (CA) and NHS-DPERG (UK), differentiate the indication and propose imaging for younger patients, atypical symptoms, rapid progression and after recent head injury. As primary diagnostic instrument MRI or CT are suggested. According to studies it is not verified whether one of the two techniques outweighs the other in terms of sensitivity for vascular changes. According to all guidelines, functional imaging such as PET or SPECT will only be applied in specific cases.
