Magnetic resonance image and its relation to Alzheimer’s disease

INTRODUCTION AND METHODS: In order to compare the magnetic resonance image characteristics of individuals belonging to pedigrees carrying the mutation E280A-PS1 associated to early onset Alzheimer disease, coming from Antioquia, Colombia, 78 individuals were studied. 47 of them were carriers of the mutation, 23 of those presented symptoms and 31 individuals being controls (non carriers of the mutation).

RESULTS: In summary, significative differences were appreciated between symptomatic individuals and those asymptomatic. There was not significant difference between asymptomatic carriers and the controls. The presence of the perihippocampal fissure constituted a difference statistically significant between the symptomatic individuals and those carriers asymptomatic and between the symptomatic ones and the controls. The interuncal distance increased significantly was another difference between symptomatic and asymptomatic individuals and among symptomatic and control group. The lobar atrophy and the ventriculomegaly were found in symptomatic individuals and they correlate with the disorder graveness. There was not significance in the presence of infarcts and/or hippocampal hyperintensities.

CONCLUSION: These results corroborate the statement that magnetic resonance image is very useful in the diagnosis and pursuiting of individuals affected by early onset Alzheimer disease.
