P 40 Correlation between hypothalamus and third ventricle of patients with affective disorders

Former studies proved the key role of the hypothalamus in the pathophysiology of affective disorders. Because of limited imaging methods and difficult delineation, attested volumetric changes has only been verified post-mortem, so in vivo studies made use of the adjacent third ventricle as an indirect marker of hypothalamic changes. Considering that these former ventricle studies leave sufficient scope for methodical improvements, it was our aim to replicate and complement these findings by using a high-resolution 7T-MRI for the first time.
