Psychiatric and neuropsychological changes in growth hormone-deficient patients after traumatic brain injury in response to growth hormone therapy.
Traumatic brain injury (TBI) has been recently recognized as a risk factor for cognitive impairment and hypopituitarism, presented most frequently with GH deficiency (GHD). GHD is associated not only with changes in body composition, but also with impaired quality of life, cognitive dysfunctions and some psychiatric sequelae, usually classified as "depression" or "atypical depression". The impact of GH therapy on mental status in TBI patients is still unknown. ⋯ GH-deficient TBI patients are depressed and have cognitive impairment. GH therapy induced reduction of depression, social dysfunction, and certain cognitive domains. Our preliminary data support the necessity of conducting randomized placebo-controlled trials on the effects of GH therapy on neuropsychological and psychiatric status in GHD TBI patients.
