Auditory verbal hallucinations

Auditory verbal hallucinations (AVH) have been described in a broad range of individuals, ranging from patients with a neurological or psychiatric disorder to hearing-disabled and healthy individuals. Although multiple studies have been conducted-and numerous theories have been proposed to account for their origins-at present, the pathophysiology of AVH remains largely unknown. As they represent a highly variegated group of phenomena, various studies have sought to classify them and to compare their characteristics in different groups. Those studies might aid in elucidating the neural basis of AVH, as phenomenologically different types of AVH are believed to result from different neurobiological mechanisms.
