Effects of auditory hallucinations on the mismatch negativity (MMN) in schizophrenia as measured by a modified ‘optimal’ multi-feature paradigm

Conclusions
This is the first study to examine MMN in SZ and to report a significant difference in duration MMN amplitude between patients and healthy within the modified (Optimal-3) multi-feature MMN paradigm. This study corroborates previous research reporting a robust duration MMN deficit in schizophrenia and supports previous findings suggesting that AHs may contribute to MMN deficits in schizophrenia.

Resting-state EEG in schizophrenia: Auditory verbal hallucinations are related to shortening of specific microstates

Conclusions
Microstates of class D resemble topographies associated with error monitoring. Its premature termination may facilitate the misattribution of self-generated inner speech to external sources during hallucinations.

Significance
These results suggest that microstate D represents a biological state marker for hallucinatory experiences.

Cognitive Behavioural Therapy for Auditory Hallucinations: Effectiveness and Predictors of Outcome in a Specialist Clinic

Conclusions: Lack of insight and presence of formal thought disorder do not preclude effective cognitive-behavioural treatment of auditory hallucinations. There is a need to further understand why negative symptoms may present a barrier to therapy.
