Basic Auditory Processing and Auditory Hallucinations (AUDISCHIZ)

Basic Auditory Processing and Acoustico-verbal Hallucinations: a Pathophysiological Study
Schizophrenia is a severe psychiatric disorder that affects approximately 1% of the population worldwide.
Although pathophysiology of this disease remains unclear, a growing interest is emerging for low-level sensory function, acknowledging that deficits in early stages of sensory processing are related to higher-order cognitive disturbances in schizophrenia.
In the field of auditory processing, symptoms as auditory-hallucinations were found correlated with disabilities to discriminate psychoacoustic parameters of sounds.

Detaljeret beskrivelse
Outcomes: Our main hypothesis is that Auditory Hallucinations Rating Scale (AHRS) scores are correlated with the percentage of wrong answers in a Tone-Matching Task test. The main objective is to assess this correlation. Our other objectives are to assess correlation between AHRS as well as other symptoms scales and psychoacoustic tests assessing intensity, length discrimination of non-verbal tones and self-monitoring abilities. Impact of therapeutic procedures (neuromodulation, psychotherapy) conducted independently of our study on these psychoacoustic tests will also be assessed.
Methods: 30 subjects with schizophrenia will be included. Clinical and psychoacoustic measures will be carried out at J-0. In the case of patients receiving therapeutic procedures independently of our study, new clinical and psychoacoustic measures will be carried out at J+7 and J+30.

Eksperimentel: 30 patients with schizophrenia
Measure the correlation between the score on the scale psychometric AHRS (Auditory Hallucination Rating Scale) to measure HAV and performance scores discrimination test psychoacoustic Tone Matching Task in subjects suffering from schizophrenia and HAV.

Our study focuses on psychoacoustic tests, specialist care protocols (psychotherapy, neuromodulation ...) being made independently of our study, as part of medical activity of Cerletti care unit or differentiated protocols.
Thus, our study shows no individual benefit for the patient.
However, a better understanding of the neurophysiological mechanisms underlying auditory hallucinatory phenomenon could allow a better management of these patients in the near future
