Deafness and Cognition in Middle-aged Adults
This study is comparing cognitive test results between middle-aged adults (45 to 64) who have severe hearing loss and those with normal hearing. It is not testing a drug or treatment — researchers are simply measuring whether significant hearing loss is linked to cognitive differences at this age group. This is a Phase NA observational study, meaning it is gathering information, not evaluating a therapy.
You may qualify if
- Cases: Patients aged between 45 to 64 years with severe to profound bilateral post-lingual sensorineural hearing loss with a maximum intelligibility of 70% (disyllabic words) in free-field silence with hearing aids at 60 dB SPL, current in french
- Controls: normal hearing subjects matched on age, sex and education level
You're excluded if
- Associated disability that prevents the tests from being performed
- Past and current history of neurological and psychiatric disorders including meningitis
- Psychotropic drug treatment
- Vulnerable subject
