title: [Spontaneous speech prosody and discourse analysis in schizophrenia and Fronto Temporal Dementia (FTD) patients].
abstract: Patients with schizophrenia and Frontotemporal Dementia (FTD) in their linguistic variants share some language characteristics such as the lexical access difficulties, disordered speech with disruptions, many pauses, interruptions and reformulations. For the schizophrenia patients it reflects a difficulty of affect expression, while for the FTD patients it reflects a linguistic issue.
  
  
  METHODS
  This study, through an analysis of a series of cases assessed Clinic both in memory and on the Mental Health Unit of HUSI-PUJ (Hospital Universitario San Ignacio), with additional language assessment (analysis speech and acoustic analysis), present distinctive features of the DFT in its linguistic variants and schizophrenia that will guide the specialist in finding early markers of a differential diagnosis.
  
  
  RESULTS
  In patients with FTD language variants, in 100% of cases there is a difficulty understanding linguistic structure of complex type; and important speech fluency problems. In patients with schizophrenia, there are significant alterations in the expression of the suprasegmental elements of speech, as well as disruptions in discourse.
  
  
  CONCLUSIONS
  We present how depth language assessment allows to reassess some of the rules for the speech and prosody analysis of patients with dementia and schizophrenia; we suggest how elements of speech are useful in guiding the diagnosis and correlate functional compromise in everyday psychiatrist's practice.
