Somatic symptom disorder has a long history. Sigmund Freud described a case of Anna, who displayed several physical conditions (e.g., pain, dizziness, numbness, and visual disturbances) with no apparent medical cause. Also, schizophrenia is not actually one single disorder but a spectrum of disorders that fall along a continuum of symptoms and functioning levels. Describe somatic symptom disorder, and if the disorder can be diagnosed if the person has an actual physical illness. Describe the basic criteria for schizophrenia based on the current DSM criteria. Explain the differences between negative and positive symptoms. Explain the prognosis of an individual diagnosed with schizophrenia based on age and gender factors. **make sure to cite your sources in your work and provide references for those citations utilizing 7th edition APA format. no plagiarism
