4 世界名画家蒙克名作《呐喊》是精神的焦虑以图式显现的最杰出的代表.
在他日记里，曾记下那激动人心的一幕： 尼斯，1892年1月22日， 我和两个朋友还在散步 太阳已快下山了 天空突然间变得血一样红 我似乎感受到了一种悲伤忧郁的气息 我止住了脚步，轻轻地倚在篱笆边 极度的疲倦已使我快要窒息了 火焰般的云彩像血，又像一把把利剑笼罩着蓝黑色的挪威和城镇 我的朋友，他继续独自地走着，而我却呆呆地站在那儿 焦虑使我不停地发抖 我感到四周似乎被一声巨大而又不断的尖叫声震得摇摇晃晃

6 Concepts Mood disorders
Group of disorders involving severe and enduring disturbances in emotion (mood) (prevalence in population between 8% and 19%)

7 Concepts Major depressive episode
Extremely depressed mood state that lasts at least 2 weeks and includes cognitive symptoms(worthlessness, indecisiveness) and physical symptoms (altered sleeping pattern, changes in appetite and weight, loss of energy)

8 Concepts Mania Episode of joy and euphoria marked by individual’s extreme pleasure in every activity, hyperactivity, little sleep

9 Concepts Hypomania less severe version of a manic episode that does not cause marked impairment in social or occupational functioning Dysphoric manic or mixed episode the individual experiences both elation and depression or anxiety at the same time

10 Concepts Unipolar mood disorder
Individuals experience either depression or mania but not both Bipolar mood disorder Individuals alternate between depression and mania

11

12 The classification of Mood Disorders
Mood (Affective) Disorders Manic episode With or Without psychiatric syrnptoims (mania) Depression (unipolar) Single episode Recurrent episode Bipolar disorders Bipolar-Ⅰ (with maina) Bipolar-Ⅱ (with hypomania) Mixed type Rapid-cycling bipolar disorder Dysthymia Cyclothymia disorder

13 心境障碍与精神病性障碍的交叉重叠 精神病性障碍 双相障碍 抑郁症 伴精神病性症状的抑郁症 双相抑郁症 难治性抑郁症
Key Point: There is considerable symptomatic and syndromic overlap between different mood and psychotic disorders. Psychosis can be a manifestation of psychotic disorders (such as schizophrenia or schizophreniform disorder), associated with mood disorders, dementia, delirium and substance-induced disorders. Depression occurs in the course of bipolar disorder, but the majority of depression is unipolar. Depression may be resistant to treatment and some cases of treatment-resistant depression may be bipolar depression that has been misdiagnosed as unipolar. Therefore, it is important to understand the epidemiology and presentation of bipolar disorder and to screen for it. 抑郁症 难治性抑郁症 13

20 Causes of mood disorders

21 Causes of mood disorders

22 Causes of mood disorders
biological factors if one twin presents with a mood disorder, an identical twin is approximately three times more likely than a fraternal twin to have a mood disorder (heritability approx. 40% for women) psychological factors

23 Causes of mood disorders
stressful life events, hopelessness, negative cognitive styles - overgeneralization social and cultural factors marital dissatisfaction 70% of people suffering with major depressive disorder or dysthymia are women

27 Treatment of mood disorders
Medications Antidepressants (number of side effects) Monoamine oxidase (MAO) inhibitors (negative interactions with tyramine) Selective serotonergic reuptake inhibitors (SSRIs) (side effects) Lithium (weight gain, danger of poisoning) Electroconvulsive therapy (ECT) and transcranial magnetic stimulation (TMS) as an alternative to ECT

28 抗抑郁药的发展史 1950s 1960s 1970s 1980s 1990s 2000+ 多作用机制抗抑郁药 （多受体作用）
选择性的抗抑郁药 （单一受体作用） 对多种单胺类靶目标有效的新药 1950s 1960s 1970s 1980s 1990s 2000+ 奈发唑酮 米氮平 文拉法辛 度洛西汀 丙咪嗪 氯丙咪嗪 去甲替林 阿米替林 去甲咪嗪 麦普替林 阿莫沙平 氟西汀 舍曲林 帕罗西汀 氟伏沙明 西酞普兰 Key Point Trends in psychopharmacology are again focusing on the role of multiple targets of action in the treatment of depression Background The modern era of psychopharmacology for depression began in the 1940s with the discovery of lithium; this was followed in 1950 by the synthesis of the antipsychotic agent chlorpromazine and continued with the discovery of the tricyclic antidepressant (TCA) imipramine. At approximately the same time, occasional euphoria was reported in tubercular patients treated with iproniazid, a monoamine oxidase inhibitor (MAOI). MAOIs began to be used as antidepressants in the 1960s The next major innovation was the availability of the first SSRI, fluoxetine, in The SSRIs lacked the dietary restrictions associated with MAOIs, and they offered safety and tolerability advantages over older tricyclic and heterocyclic agents Most recently, pharmacologic refinement has emphasized the potential combined role of NE and 5-HT in depression, as evidenced by the theoretical mechanism of action of venlafaxine. Unlike the SSRIs, which primarily inhibit only 5-HT reuptake, venlafaxine inhibits the reuptake of 5-HT and NE and has a side-effect profile similar to that of the SSRIs Venlafaxine is believed to work by inhibiting the reuptake of both 5-HT and NE Reference Lieberman JA.

43 Concepts Epidemiology Etiology Symptoms Diagnosis and differential diagnosis

44 Neuropsychology: Concepts
A science that studies the relationship between the brain, nervous system and behavior. attempts to explain the way in which the activity of the brain is expressed in observable behavior

45 Concepts Schizophrenia comprises a group of psychotic disorders of unknown specific etiology often presented with a gradual onset of abnormalities in perception, thought, motion and behavior since young adulthood. A puzzling and profound psychological disorder. - It affects thought, perception, and mood. - loss of contact with reality.

46 Epidemiology Prevalence ：
Point prevalence in China (1982): 4.75‰（rural area 3.42‰，urban 6.06 ‰ )。 Total prevalence in China(1982):5.69‰，(6.55 ‰ 1999)。 Lifetime prevalence in USA（1988）13‰。

47 Epidemiology Age：the age of onset in 50% of patients is 20~30 year old，over 80% of patients is 16~35year old. Gender： Schizophrenia occurs equally in men and women(in abroad) The prevalence in men is more than women (1.6:1) in China. The mean age of onset is about 2 to 5 years earlier in men than women.

48 Schizophrenia: Some Facts and Statistics (cont.)
Gender differences in onset of schizophrenia in a sample of 470 patients

49 Etiology biological factors 1．genetics
2．The neurodevelopmental hypothesis 3．Changes in brain structure 4．Biochemical abnormalities personality factors psycho-social factors

50 Etiology Studies Method: Family studies Twin studies Adoption studies

51 Etiology The results of family studies:
The risk of Schizophrenia. Schizoaffective disorder, and schizotypal personality is increased in first-degree relatives of patients with Schizophrenia. The risk of both Schizophrenia and mood disorder is increased in first-degree relatives of patients with schizoaffective disorder. The risk of bipolar illness is not increased in first-degree relatives of patients with schizophrenia.

52 Etiology The results of twin studies
concordance rates among MZ pairs is higher than that among control(35-60 times) concordance rates are about 50% for MZ and about 10% for DZ. It might be expected that some environmental factors relevant to etiology. The risk of schizophrenia in the offspring of an unaffected twin is the same as that of an affected twin. This means that an unaffected twin has the same genetic susceptibility to developing Schizophrenia, but for some reason the susceptibility is not expressed.

53 Etiology The results of adoption studies The rate for Schizophrenia is greater among the biological relatives of the Schizophrenia Adoptees than among the relatives of control. The finding supports the genetic hypothesis.

54 Amino acids in Schizophrenia
Biochemical studies The dopamine hypothesis. 5-HT hypothesis. Amino acids in Schizophrenia

思维贫乏(poverty of thought) 思维散漫( looseness of thought) 思维破裂(splitting of thought) 思维不连贯(incoherence of thought) 思维中断(blocking of thought) 思维被夺( thought deprivation)。 思维插入(thought insertion)和强制性思维(forced thinking) 思维化声(thought hearing) 思维扩散(diffusion of thought)和思维被广播(thought broadcasting) 象征性思维(symbolic thinking) 语词新作(neologism) 逻辑倒错性思维(paralogism thinking) 强迫观念（obsessive idea） 或称强迫性思维 内向性思维（autism）

58 Symptoms 妄想(delusion) 按其起源与其他心理活动的关系可分为原发性妄想(primary delusion)和继发性妄想(secondary delusion) 被害妄想(delusion of persecution) 关系妄想(delusion of reference) 物理影响妄想(delusion of physical influence)-被控制感。 钟情妄想(delusion of love) 嫉妒妄想(delusion of jealousy) 被洞悉感(experience of being revealed) 夸大妄想(grandiose delusion) 罪恶妄想(delusion of guilt) 疑病妄想（hypochondriacal delusion） 虚无妄想(delusion of negation)

59 Symptoms Three main kinds of mood are common:
First, there may be sustained abnormalities of mood such as anxiety ,depression, irritability, or euphoria. Second, there may be blunting of affect. Essentially this is sustained emotional indifference（冷淡） or diminution of emotional response. Third, there is incongruity of affect. Here the expressed mood is not in keeping with situation or with the patient’s own feeling.

60 Symptoms Some acute patients are normal
Others may present somewhat abnormalities of volition hypobulia abulia Parabulia（意向倒错） ambivalence paranoid schizophrenia may present hyperbulia

61 Symptoms Excitement（兴奋状态）----hebephrenic excitement, catatonic excitement Stupor（木僵）----. The patient remain motionless for a long time(catatonic stupor), or maintain their limbs or trunks in unusual positions(waxy flexibilitas ) for various lengths of time. Negativism（违拗）---- refuse to cooperate (active negativism, passive negativism) Passive obedience（被动服从）

62 Symptoms Stereotyped act-（刻板动作）---the patient repeat various functions or gestures, or imitate other’ movements(echopraxia 模仿动作) Mannerism（作态） Bizarre behavior（怪异行为） Forced act ， compulsive act Violence and suicide behavior Some patients may cause self-induced water intoxication or avoid eating because of certain delusional beliefs.

63 Auditory hallucinations 74 Delusions of persecution 64
Symptoms Symptom Frequency (%) Lack of insight Auditory hallucinations Ideas of reference Suspiciousness Flatness of affect Delusional mood Delusions of persecution Thoughts spoken aloud

64 Diagnosis and differential diagnosis

65 Diagnosis The most recent definition was offered in 1994 in DSM-IV. Characteristic symptoms ( Delusions, hallucinations, disorganized speech, catatonic behavior, and negative symptoms.) Occupational dysfunction (work, interperonal relations, or self –care, academic, failure in goal achievement) Continuous signs of disturbance for at least 6 months with a least 1 month of active phase symptoms. 65

66 Evidence for the Dopamine Hypothesis Disorder Symptom Drug Action Effect treatment
Calm Disordered thought and behavior 2. Causes tremors Schizophrenia Disordered thought and behavior Anti psychotic Decreases dopamine 66

67 Chronic schizophrenia
Symptoms meeting the diagnostic criteria of schizophrenia; The course lasts for at least 2 years.

68 CCMD-3 diagnostic criteria
Symptom criteria There is separate diagnostic criteria for simple type of schizophrenia: 1.Repeated auditory hallucinations that are usually not mood congruent; 2. Loosening of association, derailment, incoherence in thinking or poverty of thought 3.Thought insertion or withdrawal, thought block or forced thinking

69 CCMD-3 diagnostic criteria
4. Delusion of control, influence or passivity, thought broadcasting; 5. Primary delusions including delusional perception, delusional mood or other bizarre delusions; 6. Paralogic thinking, symbolic thought or neologism; 7. parathymia (情感倒错） or apathy; 8. Catatonic syndrome, unusual or silly behavior; 9. Avolition.

70 Differential diagnosis
Some neurosis 1.the feature of insight 2.the feature of symptoms 3.some patients need to be following-up

71 Differential diagnosis
Mood disorder Manic or severely depressed patients may exhibit psychotic symptoms during the peak of their disease states Accurate historical and clinical data should help to differentiate from mania-related psychotic features in the presence of other symptoms By the same token to differentiate depression from schizophrenia.

72 治疗与康复 急性治疗期（至少6周）、巩固治疗期（3－6个月）和维持治疗期（1年以上）。 1.药物治疗
早期、足量、足疗程、单一用药、个体化用药。根据病人情况、症状特点选择合适的药物。低量开始逐渐加量，高剂量密切观察不良反应。 急性治疗期（至少6周）、巩固治疗期（3－6个月）和维持治疗期（1年以上）。

73 抗精神病药物各自的靶症状 氯丙嗪 奋乃静 氟哌啶醇 利培酮 奥氮平 喹硫平 甲硫达嗪 泰尔登 舒必利 氯氮平 五氟利多 氟奋乃静癸酸酯

74 treatment of Schizophrenia
74

75 精神分裂症的维持治疗： 维持时间： 维持剂量： 首发2年维持 再发5年维持 三发以上终生维持
以往认为维持剂量为巩固治疗期剂量的1/2-1/3，甚至1/4-1/5左右。 现在认为维持量应为巩固治疗期剂量的2/3-3/4甚至全量。

76 2.电休克（ECT）治疗 3.心理与社会康复 慢性分裂症有退缩表现的患者可进行生活功能训练。
临床痊愈患者应鼓励参加社会活动和力所能及的工作。 慢性分裂症有退缩表现的患者可进行生活功能训练。
