Nocturnal sleep-related eating disorder (NSRED) is a combination of a parasomnia and an eating disorder. It is a NREM parasomnia. It is described as being in a specific category within somnambulism or a state of sleepwalking that includes behaviors connected to a persons conscious wishes or wants. Thus many times NSRED is a persons fulfilling of their conscious wants that they suppress; however, this disorder is difficult to distinguish from other similar types of disorders. Comparison with night eating syndrome
NSRED is closely related to night eating syndrome (NES) except for the fact that those with NES are completely awake and aware of their eating and bingeing at night while those with NSRED are sleeping and unaware of what they are doing. NES is primarily considered an eating disorder while NSRED is primarily considered a parasomnia; however, both are a combination of parasomnia and eating disorders since those with NES usually have insomnia or difficulty sleeping and those with NSRED experience symptoms similar to binge eating. Some even argue over whether NES and NSRED are the same or distinct disorders. Even though there have been debates over these two disorders, specialists have examined them to try to determine the differences. Dr. J. Winkelman noted several features of the two disorders that were similar, but he gave one important factor that make these disorders different.
The amount of iron in the sample is then quantified and compared to normal, and evidence of liver damage, especially cirrhosis, is measured microscopically. Formerly, this was the only way to confirm a diagnosis of haemochromatosis, but measures of transferrin and ferritin along with a history are considered adequate in determining the presence of the malady. Risks of biopsy include bruising, bleeding, and infection. Now, when a history and measures of transferrin or ferritin point to haemochromatosis,  whether a liver biopsy is still necessary to quantify the amount of accumulated iron is debatable. MRI
MRI-based testing is a noninvasive and accurate alternative to measure liver iron concentrations. Other imaging
Clinically, the disease may be silent, but characteristic radiological features may point to the diagnosis. The increased iron stores in the organs involved, especially in the liver and pancreas, result in characteristic findings on unenhanced CT and a decreased signal intensity in MRI scans. Haemochromatosis arthropathy includes degenerative osteoarthritis and chondrocalcinosis. The distribution of the arthropathy is distinctive, but not unique, frequently affecting the second and third metacarpophalangeal joints of the hand. The arthropathy can, therefore, be an early clue as to the diagnosis of haemochromatosis. Functional testing
Based on the history, a physician might consider specific tests to monitor organ dysfunction, such as an echocardiogram for heart failure, or blood glucose monitoring for patients with haemochromatosis diabetes.
