Effects of Growth Hormone on Cognition and Cerebral Metabolism in Adults With Growth Hormone Deficiency

Patients with Growth hormone (GH) deficiency often report impaired quality of life and difficulty with mental functioning. It has been suggested that GH replacement in such patients leads to improvement in cognitive function. The aim of this study is to elucidate the effects of GH replacement in patients with GH deficiency on cognitive function using structural and functional neuroimaging and cognitive testing.

Stanford is currently not accepting patients for this trial.

   Bipolar II Disorder with or without psychotic features in a major depressive episode

   - Current use of psychotropic medications

   - History of moderate to severe brain injury

   - Clinically significant cardiovascular disease
