Study Notes
Liver Cirrhosis and Liver Dysfunction
- Liver cirrhosis is a serious condition.
- Liver dysfunction can lead to the increased levels of GABA in the blood.
- The liver may fail to clear enterogenous GABA.
- Elevated GABA levels in the blood can be a symptom.
- The presentation includes diagrams of the liver and associated organs.
- Diagrams also illustrate the liver's function, and relation to the brain via the blood.
- Diagrams illustrate the processes of how the liver functions and clears metabolites from the body.
- Various processes within the liver impacting the brain are illustrated.
- Pathological conditions like the failure to clear enterogenous GABA are shown.
Hepatic Encephalopathy
- Hepatic encephalopathy is a potentially serious neurological complication associated with advanced liver disease.
- Liver failure may result in raised levels of ammonia in the blood.
- Ammonia can alter brain function leading to impaired consciousness or changes in mood and behavior, which collectively can be referred to as hepatic encephalopathy.
- Various conditions like increased levels of Ammonia from the gut can affect the brain in dysfunctioning livers.
Diagnostic Tests and Treatments
- Diagnostic tests and treatments are not listed directly.
- However, various processes, diagrams, and details give insight into how conditions are diagnosed and treated.
- Treatments likely center around managing symptoms and underlying liver disease.
- Information about potential medical interventions is implied.
Cirrhosis Pathophysiology
- Cirrhosis is a chronic, progressive disease.
- The diagrams and processes shown illustrate the complex interactions within the liver and how imbalances can affect the brain.
- The process illustrating the various organ-system connections and metabolic pathways within the liver are visualized.
- The illustrations point to how cirrhosis may lead to problems throughout the body by impacting liver function, and the overall health of the body and mind.
Normal Liver Functioning
- The liver is responsible for various essential functions in the body.
- Detailed diagrams show the complex interplay and metabolic pathways within the liver, and how issues in the liver can affect the brain.
