Substance/Medication-Induced Depressive Disorder

Diagnostic Criteria

DSM-V Diagnostic Criteria for Substance/Medication-Induced Depressive Disorder

“

A.A prominent and persistent disturbance in mood that predominates in the clinical picture and is characterized by depressed mood or markedly diminished interest or pleasure in all, or almost all, activities. AND B.There is evidence from the history, physical examination, or laboratory findings of both (1)and(2): 1.The symptoms in Criterion A developed during or soon after substance intoxication or withdrawal or after exposure to a medication. 2.The involved substance/medication is capable of producing the symptoms in Criterion A. C.The disturbance is not better explained by a depressive disorder that is not substance/medication-induced. Such evidence of an independent depressive disorder could include the following: The symptoms preceded the onset of the substance/medication use; the symptoms persist for a substantial period of time (e.g., about 1 month) after the cessation of acute withdrawal or severe intoxication; or there is other evidence suggesting the existence of an independent non-substance/medication-induced depressive disorder (e.g., a history of recurrent non-substance/medication-related episodes). AND D.The disturbance does not occur exclusively during the course of a delirium. AND E.The disturbance causes clinically significant distress or impairment in social, occupational,or other important areas of functioning. Note:This diagnosis should be made instead of a diagnosis of substance intoxication or substance withdrawal only when the symptoms in Criterion A predominate in the clinical picture and when they are sufficiently severe to warrant clinical attention. .

“

A.A prominent and persistent period of depressed mood or markedly diminished interest or pleasure in all, or almost all, activities that predominates in the clinical picture. AND B.There is evidence from the history, physical examination, or laboratory findings that the disturbance is the direct pathophysiological consequence of another medical condition. AND C.The disturbance is not better explained by another mental disorder (e.g., adjustment disorder, with depressed mood, in which the stressor is a serious medical condition). AND D.The disturbance does not occur exclusively during the course of a delirium.

Specific Phobia

Diagnostic Criteria

DSM-V Diagnostic Criteria for Specific Phobia

AND E.The fear, anxiety, or avoidance is persistent, typically lasting for 6 months or more. AND F.The fear, anxiety, or avoidance causes clinically significant distress or impairment in social, occupational, or other important areas of functioning. AND G.The disturbance is not better explained by the symptoms of another mental disorder,including fear, anxiety, and avoidance of situations associated with panic-like symptoms or other incapacitating symptoms (as in agoraphobia): objects or situations related to obsessions (as in obsessive-compulsive disorder); reminders of traumatic events (as in posttraumatic stress disorder); separation from home or attachment figures (as in separation anxiety disorder); or social situations (as in social anxiety disorder).
