Part of the problem, no doubt, is that «depression» is a
broad, poorly defined
diagnostic category, which embraces a daunting range of symptoms, including cognitive and physical lethargy, mental rumination, loss of concentration, chronic negativity and pessimism, feelings of worthlessness, and unremitting sadness.
Attachment disorganization is likely to constitute a
broad relational risk factor for psychopathology that cuts across conventional
diagnostic categories and interacts with individual biological vulnerability, producing a range of psychiatric symptoms.
