BEERSE, Belgium, November 29, 2010 /PRNewswire/ -- New research showing that psychiatrists believe more than half (53 per cent) of patients with schizophrenia are non- or partially adherent to medication was presented today at the International Early Psychosis Association (IEPA) Congress, Amsterdam (1). The research, conducted by Janssen, relates to approximately 4.45 million schizophrenia patients in EMEA (Europe, Middle East and Africa)(2).

Schizophrenia is a devastating mental illness for both the patient and their family and friends, as it seriously impairs a person's ability to think clearly, relate to others and to function properly in society. While there is no cure, many people with the illness respond well to antipsychotic drugs.

Patients who are non-adherent to medication are almost five times more likely to relapse than those patients who are adherent(3). Frequent relapses and hospitalisation can increase a person's isolation and make it even more difficult for them to find and keep a job (4,5,6,7,8). It can also lead to an increased tendency for violent acts such as suicide and homicide, particularly when substance abuse is also an issue (9,10).

The ADHES research was taken from a large survey of over 4,500 psychiatrists in 36 countries in the EMEA region(1).
