Under diagnosis of Depression and Anxiety

• Emphasis on somatic rather than cognitive/mood complaints

• Belief that depression and anxiety are a natural reaction to circumstance (counter transference)

• Reluctance to stigmatize patient with psychiatric diagnosis

• Nonspecific symptoms, overlap with medical illness

• Time limitations in primary care

Anxio-Depression A new spectrum in psychiatry

• The categorical classification of mental disorders (DSM-IV , ICD-10) has limitations

• No clear boundaries between classes of disease, or even between psychopathology and normality

• Combining several types of related disorders into a large group defined as a “spectrum” has a heuristic value : it gives new insights and permits epidemiological, genetic and above all therapeutic research

• This is especially true for anxiety and depression
