Approximately 2% to 10% of all patients with Alzheimer's disease have<unk> . Patients with schizophrenia, right frontal ischemic stroke, and rarely patients with Parkinson's disease have also reported being affected by this delusion. The exact prevalence of patients with this delusion is relatively unknown because the typical patient has many comorbidities; this makes it difficult to separate the symptoms of<unk>  from other existing psychological conditions. Furthermore, a standard neurological or neuropsychological workup tends to overlook the existence of this delusion because affected patients have extensive cognitive degeneration that is the main focus of medical attention. As such, it can be incumbent upon the patient's family to recognize symptoms of the delusion, mainly that the patient is unable to recognize him or herself in the mirror but has an intact ability to recognize the reflections of others.
