- Primary Outcome Measures
Name Time Method <p>We will measure multiple parameters such as total brain volume, grey<br /><br>matter/white matter volume, volumes of various brain structures (such as<br /><br>pituitary gland, caudate nucleus, hippocampus, hypothalamus), white matter<br /><br>connections (corpus callosum, anterior and posterior commisures), connectivity<br /><br>within the different lobes. We will further investigate the known functional<br /><br>networks within the brain by means of resting state fMRI. Longitudinal changes<br /><br>in structure and function will be assessed as well. </p><br>
