Amygdala integrity in frontotemporal dementia

Summary

The amygdala, a complex brain region with numerous projections to other brain regions, is known to play a central role in processing emotional information.  Evidence indicates that this brain region undergoes significant atrophy in many dementia syndromes, including frontotemporal dementia.

This project aims to identify the severity of the patholocial changes in the amygdala and its connections and the relations between these changes and measures of emotion processing in frontotemporal dementia subtypes and related conditions.

Synopsis

Dementia syndromes are associated with specific patterns of brain changes.  In two of the three main subtypes of frontotemporal dementia, the amygdala undergoes significant patholocial changes.  Importantly, amygdala subregions connect to different brain regions.  How these connections are affected with frontotemporal dementia is unknown.

In additon, the amygdala plays a central role in how we process emotional information.  Contributions of the subregions of the amygdala and their connections to emotion processing remain to be established.

This project will combine a range of structural neuroimaging techniques (volumetic, connectivity) to map the changes in the amagdala network across dementia syndromes and their relations to measure of social cognition and emotion processing.

Findings arising from this project will improve our understanding of the clinical profiles of these dementia syndromes.

Additional Information

The student will be located within the Brain and Mind Centre for the duration of this project.
