The role of FKBP5 genetics and epigenetics in mediating the effects of early life adversity on emotional processing brain regions in major depressive disorder
(Trinity College Dublin. School of Medicine. Discipline of Psychiatry, 2018)Major depressive disorder (MDD) is the most widespread psychiatric illness and is characterized by loss of pleasure, depressed mood, sleep disturbances and anxiety.

The aging brain : an investigation into cognitive training and resting state networks in healthy older adults
(Trinity College (Dublin, Ireland). School of Medicine. Discipline of Psychiatry, 2013)Investigating the complexities surrounding the aging brain is of vital importance if we are to fully understand the mechanisms of aging. A greater understanding of aging may perhaps pave the way for new ideas and innovations ... -

The effect of catecholaminergic genes on executive functions : a behavioural and fMRI study
(Trinity College (Dublin, Ireland). School of Medicine. Discipline of Psychiatry, 2009)This thesis describes a study in two parts aimed at elucidating genetic links to executive functions and their neurological correlates. The catecholamines (in particular dopamine and noradrenaline) are known to be heavily ... -
The effects of depression and electroconvulsive therapy on retrospective memory and general cognition : a longitudinal study
(Trinity College (Dublin, Ireland). School of Medicine. Discipline of Psychiatry, 2012)The objectives of this work were to investigate the effects of depression on retrospective memory, in addition to attention, psychomotor and executive function, in depressed patients receiving pharmacotherapy treatment ... -
The impact of schizophrenia genome wide association study genes on functional connectivity : a functional magnetic resonance imaging study
(Trinity College (Dublin, Ireland). School of Medicine. Discipline of Psychiatry, 2014)Genome-wide association studies (GWAS) have identified several genetic variants associated with increased schizophrenia risk. However, the specific mechanisms by which these variants increase risk are not fully understood. ... -
