Illness Anxiety Disorder

Very similar to DSM-IV hypochondriasis
Clinical description: * Severe anxiety about the possibility of having or acquiring a serious disease * Actual symptoms are either very mild or absent * Strong disease conviction * Medical reassurance does not seem to help

A. Preoccupation with fears of having or acquiring a serious illness.
B. Somatic symptoms aren’t present or, if present, are only mild in intensity. * If another medical condition is present or there is a high risk for developing a medical condition (e.g., strong family history is present), the preoccupation is clearly excessive or disproportionate.
C. There is a high level of anxiety about health, and the individual is easily alarmed about personal health status.
D. The individual performs excessive health-related behaviors or exhibits maladaptive avoidance.
E. Illness preoccupation has been present for at least 6 months, but the specific illness that is feared may change over that period of time.
F. The illness-related preoccupation is not better explained by another mental disorder, such as somatic symptom disorder, generalized anxiety disorder, or obsessive-compulsive disorder.
Specify whether: * Care-seeking type: Medical care, including physician visits or undergoing tests and procedures, is frequently used. * Care-avoidant type: Medical care is rarely used.

Only 20% of patients who used to meet the diagnostic criteria for DSM-IV hypochondriasis now meet criteria for illness anxiety disorder
Severe illness anxiety has a late age of onset, possibly because more physical health problems occur with aging
Often comorbid with anxiety and mood disorders
