Hepatitis In hemochromatosis, excess amounts of iron accumulate in multiple body sites, including the liver, which can lead to cirrhosis. In Wilson's disease, excess amounts of copper accumulate in the liver and brain, causing cirrhosis and dementia. When the liver is involved, alpha-1-antitrypsin deficiency and Wilson's disease tend to present as hepatitis in the neonatal period or in childhood. Hemochromatosis typically presents in adulthood, with the onset of clinical disease usually after age 50. Ischemic hepatitis (also known as shock liver) results from reduced blood flow to the liver as in shock, heart failure, or vascular insufficiency. The condition is most
Right hemisphere brain damage shifted to include right hemisphere damage (Brookshire, 2007). It is now well established that language and cognition can be seriously impaired by unilateral right hemisphere brain damage. Specific cognitive tests can help diagnose the existence of right hemisphere brain damage and differentiate symptoms from those of left hemisphere damage. Unlike the aphasias, caused by left hemisphere damage and generally resulting in focused language deficits, right hemisphere brain damage can result in a variety of diffuse deficits which complicate formal testing of this disorder (Brookshire, 2007). These formal tests assess areas such as understanding humor, metaphors, sarcasm, facial expression, and prosody.
