6-Somatororm Disorders
-Focusing is physical sx in absence of clinically significant organic disease.

31
C- Somatization Disorder -Frequently seeking & obtaining medical Rx for multiple clinically significant somatic complaints.-Complaints must begin before 30 & cannot be explained by any medical disorder or direct effects of substance.-Multiple sclerosis pt. would not be dxed by somatization. -Differentiated from medical conditions if:-Involvement of multiple organ systems (GI, neurological..).-Sx exhibit early onset & chronic course, without development of physical signs or structural abnormalities. -Absence of clinical (laboratory) abnormalities.
Course & prognosis:-Females > males.
-Less occurrence if high social class, more among poor & illiterate persons.
-Starts before 30.
-Increase among first-degree relatives.

34
D-Conversion Disorder (Hysterical neurosis, Conversion Type):-Loss or change in beady functioning that can’t be explained by any medical disorder, & occurs in response to psychological stress. -In females > males.-Usually starts in adolescence or young adulthood.-Medical exams do not reveal physical abnormality.-Pt. is not conscious of producing sx.-Histrionic personality pt: more exposed than others. -Could happen if exposed to great stress. -Loss or change can give sensory/motor sx or both.
35
Motor sx: Abnormal tremors, jerky movements. * Note: hysterical conversion tremors: it is irregular & disappears if attention moved to another subject, etc…-It differs from tremor in anxiety.
-Hysterical aphonia: Pt. can’t speak, but can understand what is said.
* Note: to differentiate, ask pt. to cough, if he does so, means vocal cords ok & is hysterical.
Comparison b/w organic & hysterical paralysis:
Tics: involuntary movement increases in embarrassing situations.
Hysterical comas: like normal sleep, doesn’t respond to stimuli, needs care for urination & defecation, usually needs hospitalization, used to escape from reality.
Hysterical fits: differ from organic epilepsy as following: Sensory symptoms: Anesthesia or loss of sensation in a part of body or one half of body.Hysterical deafness.Loss of olfactory or taste senses.Hysterical blindness.
Prognosis:-Duration is brief. -Starts & stops abruptly.-Tends to recur. -Prognosis is poor if secondary gain is high.*Primary gain: Gain achieved by converting anxiety to somatic sx (symbolic of unconscious conflict).*Secondary gain: Gain achieved by sx, pt. pain relieved from work or gets attention & sympathy from family by taking sick role.
Rx:-Exclude organic disease by physical exam.
-Psychotherapy:-Telling pt. that he has no physical problems & sx are psychological stress & will disappear if pt. expresses his feelings.
-Amytal: may be used to produce a state of relaxation & re-experience trauma which enable pt. to talk freely about her troubles.
39

5-Duration of disturbance at least 6 months.
6-Condition is not better accounted for by another anxiety disorder, somatization disorder, or major depressive episode (Pt. may show sx of anxiety or depression).
Course & prognosis:-Mostly starts in 20’s.-1/3 of pts. don’t improve & social/vocation disturbed.-Males & female: equal.
Rx:-Exclude any organic factor.-Invasive procedure should be avoided.-Psychotherapy: preferred treatment even pt. resists this therapy (may accept it by a physician).-Group psychotherapy: Rx of choice (pt.’s social support & interaction can improve their condition).-Drugs not used unless depression/anxiety present.
