Abstract
This study was conducted on thirty patients diagnosed clinically as dementia
patients. They were 16 males and 14 females. Their age ranged between 50 and 76 years.
The aim of this work is to study the role of magnetic resonance imaging and
magnetic resonance spectroscopy in evaluation of dementia patients.
All patients were subjected to full history taking and thorough clinical examination.
Magnetic resonance imaging was performed at 1.5 Tesla MR system using a standard head
coil. Imaging included conventional MRI and proton magnetic resonance spectroscopy.
Proton magnetic resonance spectroscopy was done using multi-voxel technique.
The study was conducted on thirty patients clinically diagnosed as dementia, ten of
the patient were AD dementia, 14 were vascular dementia and the remaining six were
Parkinson disease dementia.
By conventional MRI each patient was assessed for MTA scale for medial temporal
lobe atrophy, Fazekas scale and NINDS-ARIEN criteria for vascular lesions and for the
presence of abnormal findings in the substantia nigra.
We found that the grade of medial temporal lobe atrophy was higher in patients with
AD than in the other two types of dementia, still we found that this finding is not reliable
when differentiating between dementia subtypes as in our study there were two out of ten
patients with AD that did not show appreciable medial temporal lobe atrophy, while on the
other hand two patients with VaD showed grade 4 on MTA scale.
