  1. Psychiatric symptoms and diagnosis 主講者: 傅綢妹副教授

  2. 疾病分類的目的 • 有共同的診斷分類,臨床上才能溝通病人的症狀、預後、治療。 • 在研究工作上才能找到各種群組病人相互比較分析。

  3. Diagnosis and Classification DSM-IV: Diagnostic and statistical manual of mental disorder, 4th edition. (1994) DSM-IV TR (Text Revision2000) ICD-10: International classification of diseases 10th version. (1992)

  4. Classification of Mental Illness精神疾病分類

  5. Organic mental disorders( Organic brain syndrome )器質性腦症候   由腦組織功能受損所引起或與之有關的一種疾患。 可能表現為定向力障礙、記憶力喪失及學習、理解、計 算與實行判斷諸能力的缺損。可到達精神病之地步,亦 可不達於此地步,可為輕微、中度或嚴重。單純的醉酒 可做為非精神病性器質性腦症候群之一例,而老年期癡 呆則已達精神病的地步。

  6. Functional disorder 功能性障礙 沒有器官組織構造上的變化或很明顯的原 因所導致的障礙.如multiple personality disorder

  7. Psychosis 精神病   一種嚴重的器質性或功能性的精神疾患,病人的思 考、感情反應、記憶、溝通、了解現實及產生適當行為 的能力已受到足夠的損害,以致無法面對生活的正常要 求,其特徵常為退化的行為、不相稱的情緒、薄弱的衝 動抑制力及種種異常的精神內涵如妄想和幻覺。此名詞 適用的範圍很廣,可以有不同程度的嚴重性及發病期。

  8.

  10. DSM-IV Axis II: Personality Disorders and Mental Retardation Paranoid personality disorder Schizoid personality disorder Schizotypal personality disorder Antisocial personality disorder Borderline personality disorder Histrionic personality disorder Narcissistic personality disorder Avoidant personality disorder Dependent personality disorder Obsessive-compulsive personality disorder Personality disorder not other wise specified Mental retardation

  22. ICD-10 There are clinical description and diagnostic guidelines for psychiatric disorders. A supplement for providing diagnostic criteria for research is also available. It uses a three-axis system: Axis I – Clinical Diagnosis Axis II – Disablements Axis III – Contextual Factors

  23. 根據美國精神疾病診斷手冊第四版【DSM-IV】 • 一、精神分裂症的診斷標準如下: • A症狀:下列中含有兩項﹝或兩項以上﹞症狀,每一項症狀出現至少一個月: • 1.妄想:是一種錯誤且偏離事實的想法,雖然經過不斷的解釋或事實證明,仍無法改變其想法(如,認為有人要害他的被害妄想、認為旁人的一言一行都與他有關的關係妄想等)。 • 2.幻覺:是一種知覺障礙,有視、聽、觸幻覺等,精神分 裂症以「聽幻覺」最常見;在別人聽不到或旁邊沒有人講話時,但病人可清楚且確定的聽到有人對他說話的聲音。

  24. 【DSM-IV】 • 注意:若妄想內容古怪,或幻覺包含一種人聲繼續不斷評論病人的行為或思想,或幻覺為兩種或兩種以上的聲音彼此交談,則症狀僅需一項即可。 • 3.語無倫次或常表現脫軌語言。 • 4.混亂﹝disorganized﹞或僵直﹝catatonic﹞的行為。 • 5.負性病徵,如情感淡漠、貧語症﹝alogia﹞或無動機﹝avolition﹞。

  25. 【DSM-IV】 • B社會職業功能障礙:自從疾病開始發生後,主要職業功能領域諸如工作、人際關係、或自我照顧等,有一種或一種以上領域的功能明顯低於病發前的水準﹝或若發病是在兒童期或青少年期,也指不能達到其人際關係、學業、或職業成就的預期水準﹞。 • C總時期:連續有病徵的時期至少延續六個月,此六個月時期內必須至少一個月時期﹝若成功的治療可更短﹞,其症狀符合準則A即活躍期症狀,此六個月並可包含前驅症狀或殘餘症狀的時期。在這些前驅期以及殘留期內,此障礙的病徵可能

  26. 【DSM-IV】 • 只表現負性症狀、或兩種或兩種以上符合準則A,但以較弱化的型式﹝attenuated form﹞表現的症狀﹝如古怪的信念、不尋常的知覺經驗﹞﹝孔繁鐘和孔繁錦,民86﹞。 • D已排除被診斷為重鬱症及躁鬱症疾患的可能。 • E 已排除被診斷為器質性腦疾患的可能。 • 精神分裂症的症狀若持續六個月,診斷即可成立。文獻指出四分之三的病人在17-25歲時發(Stuart & Sundeen, 1995﹞。若持續6個月至2年即屬亞急性,若超過2年即屬一種慢性疾病。

  27. 精神分裂病的五項特徵 對壓力適應力薄弱;小量及中量的壓力即導致病態反應。 調適能力差;無法執行日常生活活動包括處理錢財、做三餐、個人衛生等。 依賴;無助需要家人、朋友及社會資源的支持 人際關係困難;個體感到孤獨、被隔離、顯得畏縮,有困難發展及維持人際關係。 在競爭的場合中工作有困難;個體有困難找到工作及維持一個固定工作﹝Gary & Kavanagh, 1991﹞

  28. 憂鬱症的三層面 • 情緒低落:常想哭泣,什麼都不感興趣,甚至鬱卒到想自殺或出現自傷、他傷之行為。 • 認知障礙:自責很強,罪惡感重,悲觀,覺得人生無意義,注意力和記憶力大大減低,遇事無法做出決定。 • 身體症狀:嚴重失眠,很疲倦,體力很差,胃口下降,體重減輕,性慾減退

  29. DSM-IV重鬱症之診斷準則-1 • A.至少兩週期間內,同時出現下列症狀五項(或五項以上),且呈現由原先功能的改變:(1)憂鬱心情、(2)失去興趣或喜樂此兩項症狀至少有其中之一。 • 憂鬱心情,幾乎整天都有,幾乎每日都有,可由主觀報告(如感覺悲傷或空虛)或由他人觀察(如看來含淚欲哭)而顯示。注意:在兒童及青少年可為易怒的心情。

  30. DSM-IV重鬱症之診斷準則-2 • 在所有或幾乎所有的活動,興趣和喜樂都顯著減少,幾乎整天都有,幾乎每日都有(可由主觀報告或由他人觀察而顯示)。 • 非處於節食而明顯體重下降,或體重增加(如:一個月體重變化量超過5%);或幾乎每天都食慾減少或增加。注意:在兒童,無法增加預期應增的體重即應考慮。 • 幾乎每日失眠或嗜睡。 • 幾乎每日精神運動性激動或遲滯(可由他人觀察得到,而非僅主觀感受不安定感或被拖滯感)。

  31. DSM-IV重鬱症之診斷準則-3 • 幾乎每日疲累或失去活力。 • 幾乎每日有無價值感,或過分、不合宜的罪惡感(可達妄想程度)(並非只是對生病的自責或罪惡感)。 • 幾乎每日思考能力或專注能力減退、或無決斷力(由主觀陳述或經由他人觀察而顯示)。 • 反覆想到死亡(不只是害怕自己即將死去)、重複出現無特別計畫的自殺意念、有過自殺嘗試、或已有實行自殺的特別計畫。

  32. DSM-IV重鬱症之診斷準則-4 • B.此症狀不符合混合發作的準則 • C.此症狀造成臨床上重大痛苦,或損害社會、職業、或其他重要領域的功能 • D.此障礙非由物質使用或身體疾病的直接生理效應所造成 • E.此症狀無法以傷慟反應做更佳解釋
