2-Post Traumatic Stress Disorder (PTSD) -Pt. must have experienced traumatic event prior to onset of Sx. -Pt. may have experienced event, witnessed it, or have been confronted with event that involved actual or threatened death or serious injury. -Event should be outside range of usual human experience. -Pt. response: intense fear, helplessness or horror. 14
-Pt. will have Sx from 1-3 months (Acute) or 3-6 months(Chronic) - Event cause this disorder could be: 1-Natural: Earthquakes, volcans. 2-Man-made: Rape, Torture. -PTSD could happen in one individual or more among group.

Course & prognosis: -May occur in any age after event (1wk-30 yrs). -Sx: fluctuating & become severe during stressful events. -Acute PTSD lasts for 3 months). -30% of pts. with PTSD recovers, 40%slight symptoms, 20%moderate symptoms,10% become worse. -Prognosis is conditioned by: rapid onset, good pre- morbid functioning & good social support. -Complications: social phobia disturbance in relations with others guilty feeling that may lead to suicide.
*Rx: 1-Drugs: Tofranil ( Imipramine), Inderal ( Propanolol). Catapress (Clonidine). 2-Psychotherapy: -Cognitive-behavioral approach: 1-Building good relationship with pt. 2-Cognitive appraisal of event & explaining to pt. effect of stress on human being & that symptoms are a normal outcome to an abnormal situation. 18
3-Relation training & desensitization by building a hierarchy of stressful moments & relaxation. 4-Social support & involving family & friends in caring & understanding pt.'s condition. 19

Prognosis: -May start in any age but is > in 20s & 30s. -Mainly chronic & may continue for life. -Complication: is panic attack. -other complication: addiction because of self-treatment. Rx: 1-Drugs: should decrease prescribed anti-anxiety as possible (because disorder is chronic). 2-Psychotherapy: Rx of choice. a-Psychoanalytic psychotherapy: through long-term insight. b-Behavioral psychotherapy: focuses on desensitization with entrance to cognitive therapy aims to stop conditioning in addition to relaxation & modifying behavior. 22
5- Obsessive Compulsive Disorder 1-Obsession: undesirable but persistent thought or idea forced into consciousness & can’t be erased or dismissed, thought may be trivial or morbid. Always distressing or anxiety provoking. 2-Compulsion: unwanted urge to perform act or ritual contrary to pt.'s ordinary conscious wishes or standards. -Uncontrolled & done to relieve extreme tension. -Obsession produces anxiety managed by compulsive act. 3-Obsession compulsion: repetitive acts or rituals to release tension or relieve anxiety. -Pt. carries out these acts even if he recognizes that they are inappropriate or foolish. 23
Examples: a. Endless hand washing. b. Checking re-checking doors if they're locked. c. Elaborate dressing rituals. -Pt. is trying to resist this, but because of long period of disorder, resistance may decrease. -As a result, pt. will have much difficulties in social r/s. -Pt. is neurotic (because pt. believes that these ideas are not true & silly). 24
Course & prognosis: -Usually starts in adolescence. -Chronic disorder & pt. may not present to psychiatrist for 5-10 years. -About 30% of pts.: good improvement, 30- 40%: mild improvement, & the rest: chronic or worse. -Some pts. may have depression, suicide or addiction. 25

6-Somatororm Disorders -Focusing is physical sx in absence of clinically significant organic disease. A-Body Dysmorphic Disorder -Preoccupation with imagined defect in appearance. -Slight anomaly: concern is excessive. -Significant distress or impairment in social or occupational functioning. -Preoccupation is not better accounted for by another mental disorder. 27
Course & prognosis: -Starts in adolescence, 20’s or 30’s, stays constantly & may have result of social & vocational disability. -Complication: Plastic surgeries without any need. Rx: -Pts. refuse psychotherapy despite their severe suffering & insist on having plastic surgeries so it is important for plastic surgeon to refer them to psychiatrist or psychologist. -Meds. may relief Sx (anti-anxiety, anti-depression). -Long-term psychotherapy is recommended.
B- Pain disorder -Clinical presentation of pain in 1 or > anatomical sites. -Pain is severe to warrant clinical attention & causes major impairment in 1 or > areas of functioning. -Psychological factors play important role in onset, severity exacerbation, or maintenance of pain. -Acute: less than 6 months (duration). -Chronic: more than 6 months (duration). Course & prognosis: -In female double than males. -Increase at 4 th & 5 th decade & b/w poor persons. 29
Rx: Drugs: Giving analgesics or narcotics is not useful (?addiction). -Anti-depressant can be given: (Elatrol) or (Prozac). -Anxiolotics or analgesics usually not effective. Psychotherapy: Important that therapist helps pt. recognize psychogenic origin of pain. -Explain to pt. how person state of mind affects how much pain he can feel. -Relaxation technique, sports exercice. -Biofeedback. -Sometimes, admission to hospital is needed to control feeling of pain (behavioral, cognitive & group psychotherapy may be used).
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. 31
Course & prognosis: -Females > males. -Less occurrence if high social class, more among poor & illiterate persons. -Starts before 30. -Increase among first-degree relatives. -Chronic & pt. is rarely free of sx or for medical seeking.
Rx: -Long & empathic r/s with one therapist. -Using meds. is not recommended but anti- depressant or anxiolytics can be used symptomatically if anxiety or depression is present (?addiction).
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. 34
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. 35
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.
E-Hypochondriasis -6 major criteria associated with disorder: 1-Pt is preoccupied with fears of having-or idea of having serious medical disorder based on his/her interpretation. 2-Misinterpretation of bodily sx persists despite appropriate medical evaluation & reassurance. 3-Pt’s preoccupation with Sx is not as intense or distorted as in body dysmorphic disorder. 39
4-Preoccupation causes clinically significant distress or impairment in social, occupational, or major areas of functioning. 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). 40
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.
Comparison b/w Somatization & Hypochondriasis SomatizationHypochondriasis 7 yrs needed for dx6 months for dx Look about sx & Rx Look about disorder behind sx C/O 13 or >sxC/O 1 or 2 sx Doesn’t like Dr. visitMultiple Dr. visit 42
7-Dissociative Disorders -Disruption in usually integrated functions of consciousness, memory, identity & perception of environment. A. Dissociative Amnesia -1or > episodes of inability to recall important personal information (traumatic or stressful nature); too extensive to be explained by ordinary forgetting. -Disturbance doesn’t occur during Dissociative Identity Disorder. -Not due to substance effects or general medical condition. -Most common in females. 43
-Usually pt. is aware of memory loss. -Pt. is usually alert & not confused (Some pts. describe a state of clouded consciousness). -Onset is sudden & recovery is sudden & complete. -Recurrence is rare. 44
Rx: -It is important to differentiate psychogenic amnesia from organic amnesia ( CVA,P.C, etc..). -Amytal interview: Pt. is given short or medium acting barbiturates as Amytal IV & in a state of alleged consciousness pt. is helped to remember. -Hypnosis: Under hypnosis, pt. is relaxed & in a somnolent state in which inhabitations are weekend, & repressed memories can be reached. -Psychotherapy: After repressed memory is reached psychotherapy helps pt. resolve conflicts.
B. Dissociative Fugue -Sudden, unexpected travel away from one’s home or place of work, with inability to recall one’s past. -Confusion about personal identity or assumes new identity, which may be partial (filling in the blanks). -Disturbance doesn’t occur in context of a dissociative identity disorder, & is not due to effects of a substance or to a general medical condition. 46
-When fugue is over, pt. remembers all he had forgotten but forgets what happened during fugue. -Course is usually short. -Pt. recovers suddenly & completely to find himself in a strange place. -Recurrence is rare. Rx: -No Rx is required if duration is short. -Hyposis & Amytal interview maybe used to help pt. remember his identity.
C. Multiple Personality Disorder (Dissociative Identity Disorder) -2 or > personalities (each complete & integrated). -At any time, pt. is dominated by one personality & unaware of presence of other personalities. ->in females. -Mostly occur in adolescence or early adulthood. -Predisposing factor: severe physical/sexual abuse in childhood. -Epilepsy is found in 25% of pts. -EEG shows difference in activity in different personalities in the same pt. 48
-Each personality is integrated & differ in mood, attitude, name, etc… -Usually each personality doesn’t recognize presence of other personalities (Sometimes one of them knows about the other). -Pt. may find himself in strange place or hearing voices inside him or another person taking control over him. -Chronic disorder.
