In most patients the formal onset of Schizophrenia is preceded by a period of symptoms, known as the prodromal period.[Lieberman et al., 2001] Symptoms in this stage can include mood disturbances and cognitive symptoms.[Lieberman et al., 2001; McGlashan, 1996] Treatment with antipsychotic therapy can ameliorate psychotic symptoms, and maintenance therapy is effective in preventing relapse.[Lieberman et al., 2001] The presentation covers the progression of Schizophrenia and functional decline.
