A psychiatric diagnosis is usually given by a doctor or mental health specialist on the basis of what someone says about their thoughts, feelings and experiences, alongside observations about their behaviour. In the US, clinicians use the DSM-5 to make a psychiatric diagnosis, whereas in the UK they mainly use the ICD-10 system.
Around 75% of people with a diagnosis of schizophrenia hear voices. Voices can also occur in people who have a diagnosis of psychosis, bipolar
Many people think that voices that are loud, commanding, and come from an external location are more of a worry than those that are experienced as occurring ‘inside the head’. In the past, people thought that these kind of voices were typical of schizophrenia. However, research suggests that the volume, content or perceived location of a voice is not relevant to the type of diagnosis a person may receive. There is little evidence for the once widespread view that ‘internal voices’ – i.e. voices that occur ‘inside the head’ – are somehow more benign than those that appear to come from an external location.
Some people who hear voices find psychiatric diagnoses helpful, others find them stigmatising and harmful. What is important to understand is that hearing

Some think they are best understood as describing patterns of experience, thoughts and behaviour that may be distressing or disruptive.

Many people who hear voices live well with their experiences without ever needing mental health support. Watch the short animation below to find out more about the latest research in this field.
