Participants in this research study have been diagnosed with a carcinoid tumor. The purpose of this research study is to improve understanding of cognitive (thinking) and emotional functioning in people with carcinoid tumors.
Serotonin is an important neurotransmitter, a type of chemical that helps relay signals from one area of the brain to another. The functioning of the serotonin system is disrupted in carcinoid syndrome. Serotonin is known to play a key role in emotional regulation and cognitive (thinking) functioning.
The purpose of this study is to examine the impact of carcinoid tumors on neuropsychological functioning (attention/concentration, multitasking, learning/memory) and emotional regulation (mood, anxiety, personality). Investigators hope that this study will provide essential information to enable them to better help individuals with carcinoid tumors.
Approximately 50 people will take part in this study at the University of Iowa.
