To the Editor: In his editorial, published in the January 2010 issue of the Journal, John H. Gilmore, M.D. (1), argues for a developmental perspective in relation to schizophrenia. However, it is perhaps no longer accurate to argue that "most studies have focused on pre- and perinatal environmental risk factors" (1, pp. 8, 9). Recently, researchers have found a range of adverse events in childhood to be significant risk factors for developing psychotic symptoms and/or being diagnosed with schizophrenia, even after controlling for family history of psychosis or schizophrenia in some cases. These adverse events include early loss of a parent; parental poverty; bullying; witnessing parental violence; emotional, sexual, or physical abuse; physical or emotional neglect; and insecure attachment (2, 3).
