presymptomatic การใช้

• Presymptomatic diagnosis of MJD can be made with a genetic test.
• However, PrP Sc levels are very low in presymptomatic hosts.
• These practices include extensive observations of the patients and studying both the presymptomatic and remissive phases of mental illness along with the periods of acute illness.
• Studies indicate that children carrying the disease genotype benefit from presymptomatic counseling in order to prepare for the physical and social implications associated with progressive vision loss.
• Presymptomatic testing for HD has also influenced testing for other illnesses with genetic variants such as polycystic kidney disease, familial Alzheimer's disease and breast cancer.
• "This suggests that Alzheimer's disease has a presymptomatic phase, where lesions have appeared in the brain but have not reached the critical threshold for cognitive declines to appear,"
• Reduced levels of the mitochondrial enzyme succinate dehydrogenase ( SDH ), the main element of complex II, are observed post mortem in the brains of patients with Huntington's Disease, and energy metabolism defects have been identified in both presymptomatic and symptomatic HD patients.
• Pre-symptomatic late infantile MLD patients, as well as those with juvenile or adult MLD that are either presymptomatic or displaying mild symptoms, can consider bone marrow transplantation ( including stem cell transplantation ), which may slow down progression of the disease in the central nervous system.
• SOFIA meets the needs of increased sensitivity in the detection of prion diseases in both presymptomatic and symptomatic TSE infected animals, including humans, by providing methods of analysis using highly sensitive instrumentation, which requires less sample preparation than previously described methods, in combination with recently developed Mabs against PrP . The method of the present version of SOFIA provides sensitivity levels sufficient to detect PrP Sc in brain tissue.
