The dimensional Research Domain Criteria project currently being developed by the U.S. National Institutes of Mental Health, may be the specific problem solving framework psychiatry needs to develop a more scientifically mature understanding of schizoaffective disorder as well as all other mental disorders. Treatment
The primary treatment of schizoaffective disorder is medication, with improved outcomes using combined long-term psychological and social supports. Hospitalization may occur for severe episodes either voluntarily or (if mental health legislation allows it) involuntarily. Long-term hospitalization is uncommon since deinstitutionalization started in the 1950s, although it still occurs. Community support services including drop-in centers, visits by members of a community mental health team, supported employment and support groups are common. Evidence indicates that regular exercise has a positive effect on the physical and mental health of those with schizoaffective disorder.Because of the heterogeneous symptomology associated with schizoaffective disorder, it is common for patients to be misdiagnosed. Many people are either diagnosed with depression, schizophrenia, or bipolar disorder instead of schizoaffective disorder. Because of the broad range of symptoms of Schizoaffective disorder, patients are often misdiagnosed in a clinical setting. In fact, almost 39% of people are misdiagnosed when it comes to psychiatric disorders.While various medications and treatment options exist for those diagnosed with schizoaffective disorder, symptoms may continue to impact a person for their entire lifespan.Schizoaffective disorder can affect a persons ability to experience a fulfilling social life and they may also exhibit difficulty forming bonds or relationships with others.
The wall of telangiectasias is unusually friable, which explains the tendency of these lesions to bleed.All genes known so far to be linked to HHT code for proteins in the TGF-β signaling pathway. This is a group of proteins that participates in signal transduction of hormones of the transforming growth factor beta superfamily (the transforming growth factor beta, bone morphogenetic protein and growth differentiation factor classes), specifically BMP9/GDF2 and BMP10. The hormones do not enter the cell but link to receptors on the cell membrane; these then activate other proteins, eventually influencing cellular behavior in a number of ways such as cellular survival, proliferation (increasing in number) and differentiation (becoming more specialized). For the hormone signal to be adequately transduced, a combination of proteins is needed: two each of two types of serine/threonine-specific kinase type membrane receptors and endoglin. When bound to the hormone, the type II receptor proteins phosphorylate (transfer phosphate) onto type I receptor proteins (of which Alk-1 is one), which in turn phosphorylate a complex of SMAD proteins (chiefly SMAD1, SMAD5 and SMAD8). These bind to SMAD4 and migrate to the cell nucleus where they act as transcription factors and participate in the transcription of particular genes. In addition to the SMAD pathway, the membrane receptors also act on the MAPK pathway, which has additional actions on the behavior of cells. Both Alk-1 and endoglin are expressed predominantly in endothelium, perhaps explaining why HHT-causing mutations in these proteins lead predominantly to blood vessel problems.
