  • 목적: 공황장애에 대한 다양한 신경해부학적 모델들이 제안되었으나, 인지행동치료와 관련된 뇌 신경학적 기전에 대한 해석은 불명확하다. 본 연구에서는 공황장애 환자에서 CBT 전과 후에 뇌관류 변화를 평가하고 이에 따른 신경해부학적 연관성을 평가하고자 한다. 대상 및 방법: DSM-IV 기준으로 진단된 공황장애 환자 7명(남자 5명, 여자 2명, 평균연령 $45{\pm}11.0$세)을 대상으로 8주 동안 인지행동치료를 했으며, 건강한 정상인 12명(남자6명, 여자 6명, 평균연령 $42{\pm}9.5$세)을 대조군으로 사용하였다. 모든 환자들에게 인지행동치료 전과후에 $^{99m}Tc-ECD$ 뇌관류 SPECT, PDSS-SR과 ACQ점수를 각각 평가하였다. 인지행동치료 도중에는 약물치료를 실시하지 않았다. 모든 영상은 공간적으로 평준화와 편평화를 하여 SPM2를 이용하여 통계적으로 분석하였다. 결과: 공황장애 환자에서 인지행동치료 후 자각적인 증상들이 개선되고, 인지행동 평가 척도와 인지적 불안점수가 유의미하게 감소하였다(p<0.05). CBT치료 전에 띠이랑, 시상, 중간뇌와 전두엽과 측두엽에서 뇌관류가 증가하고, 우측 아래 전두엽에서 뇌관류가 감소함을 관찰하였다. 그리고 8주간의 CBT후 임상 소견의 호전과 함께 좌반구의 해마이랑, 우반구의 띠이랑와 도, 그리고 좌우 전두엽과 측두엽에서 뇌관류가 감소를 하였고 후두엽, 두정엽과 전두엽 일부에서 뇌관류가 증가한 소견을 관찰할 수 있었다. 결론: 공황장애 환자에서 약물치료 없이 인지행동치료만으로도 그 증상을 감소시키는 효과를 보였고, 이는 공포와 관련된 뇌영역에서 뇌활성도의 완화 및 안정화로 인해 치료 효과가 나타남을 알 수 있었다.

  • Objective : Hydrocephalus and vasospasm are the common complications following subarachnoid hemorrhage (SAH). In spite of development of perioperative management and operative technique, hydrocephalus cause neurological deficit and poor prognosis. Usually CSF drainage procedure(external ventricular drainage(EVD) or shunt) is needed in hydrocephalus following SAH. The aim of this study was to investigate whether the need for shunting and the outcome after shunting in hydrocephaus following SAH can be related to the duration, daily and total amount of cerebrospinal fluid(CSF) drainage at EVD. Material and Method : IVH is one of several factors which cause hydrocephalus. In this retrospective study, firstly we investigated the incidence of IVH in total cases and frequency of IVH according to aneurysmal site and then prognosis of IVH following SAH. Among 629 patients with SAH, hydrocephalus was diagnosed by CT scan and symptoms. And then those 102 hydrocephalus following SAH were divided into two groups which were hydrocephalus with IVH group and without IVH group. In these two groups, we investigated and compared the incidence of hydrocephalus in all case, frequency of hydrocephalus according to aneurysmal site, the outcome according to H-H grade on admission and the need rate of shunt, etc. Of those hydrocephalus, 100 EVD procedures were done. The duration, daily and total amount of CSF drainage at EVD were investigated. Fifty cases expired during EVD was excluded. We analyzed whether the need rate of shunt and the final outcome after shunting can be related to IVH, the duration and daily and total amount of CSF drainage. Result : The incidence of hydrocephalus following SAH was 20%(with IVH group ; 64%, without IVH group ; 11%). As H-H grade on admission was better, the outcome of hydrocephalus was also better. The mortality rate of hydrocephalus with IVH was 64% which was higher than 40% that of hydrocephalus without IVH. The need rate of shunt in all cases of hydrocephalus following SAH was 20%, but those with IVH group excluding expired patients before shunt was 40%. This was very similar to 41% of the need rate of shunt in hydrocephalus without IVH. The total amount of CSF drainage was statistically related to the need rate of shunt(total amount : need rate of shunt/<1000cc : 15%, 1000-2000cc : 40%, >2000cc : 50%). The duration and daily amount of CSF drainage were not statistically related to the need rate of shunt, but as daily amount of CSF drainage was more and duration was longer, the need rate of shunt was increased(daily amount : need rate of shunt /<100cc : 16%, 100-200cc : 25%, >200cc : 40%//duration : need rate of shunt/<1week : 8%, 1-2weeks : 30%, >2weeks : 47%), and also the final outcome after shunting was poor. Especially the total amount of CSF drainage was significant related to the final outcome after shunting(total amount : GOS/<1000cc : I&II(3/4), 1000-2000cc : II(2/4), III(2/4), >2000cc : III&IV(6/7)). Conclusion : This study revealed that the incidence and mortality rate of hydrocephalus following SAH were influenced by IVH. So SAH associated IVH has the higher incidence of hydrocephalus and poor outcome. As the CSF drainage amount was more and duration of drainage was longer, the need rate of shunt was increased and the final outcome after shunting was poor. Especially the total amount of CSF drainage were strongly related to the need rate of shunt and the outcome after shunting.

  • 인지기능 저하는 장 단기 기억 및 주의력 소실과 우울증, 불안증의 증가를 특징으로 한다. 또한, 인지기능 저하는 알츠하이머, 파킨슨병과 같은 다양한 퇴행성 뇌질환과 연관되어 있다. 경제적 부담, 안전 위협을 포함하는 인지기능 저하와 관련된 사회적 문제는 고령화가 진행됨에 따라 증가하고 있다. 이러한 문제를 해결하기 위해 전 세계적으로 많은 연구가 수행되고 있다. 일반적으로 인지기능 저하를 유발할 가능성이 있는 원인으로는 노화에 따른 대사 및 호르몬 불균형, 감염, 약물 오남용, 신경세포 손상 등이 알려져 있지만 다양한 요인이 관련되어 있으므로 원인 규명이 어려운 한계점 때문에 뚜렷한 치료전략 수립이 어려운 실정이다. 최근의 연구에 따르면 퇴행성 뇌질환 발생의 원인과 이에 대한 치료전략 수립에 있어서 장내미생물의 역할이 중요하게 제시되고 있다. 특히, 알츠하이머병과 파킨슨병에서 장내미생물 조성의 변화 및 이들에 의한 대사산물에 따른 분자생물학적, 신경행동학적 증상의 변화가 밝혀졌다. 알츠하이머병 동물모델에서 장내미생물의 변화는 NMDA 수용체와 글루탐산의 변화를 통해 기억능력 소실을 야기하였다. 반면, 알츠하이머병 동물모델에 프로바이오틱스를 투여하였을 때, 비정상적인 신경학적 행동이 유의적으로 감소하였다. 파킨슨병은 장내미생물 군집의 변화와 직접적인 연관성을 보였으며 이는 이차적 증상인 변비 발생에도 영향을 미치는 것으로 나타났다. 파킨슨병 동물모델에 투여한 프로바이오틱스는 단쇄지방산 중 하나인 뷰티르산 증가를 통한 신경세포 보호효과를 나타내었다. 또한, 알츠하이머병과 파킨슨병에서 뇌-혈관장벽의 기능이상이 밝혀졌으며, 뇌-혈관장벽 변화는 장내미생물 불균형에 의한 전신성 염증에 따른 미세소관의 파괴 및 투과성 증가와 연관된 것으로 나타났다. 더불어 장내미생물 대사과정에서 생성된 대사산물은 퇴행성 뇌질환의 발생과 치료에 영향을 미친다. 본 논문에서는 인지기능 저하의 진행을 지연시킴으로써 심화를 방지할 수 있는 효과적인 접근법을 제시하기 위하여 인지기능 저하와 장내미생물의 연관성을 심층적으로 고찰하여 치료적 대안으로 제시하고자 한다.

In the distinction of an economic state, the middle classes most accounted for 73.5% and the upper classes, least for 2.9%. In the distinction of their academic careers, graduates of a primary school most accounted for 26.9% and graduates of university, for 14.1%, of which patients, having the ability to decode the national language, reached to 11.3%. In the distinction of the house form, people living in independent houses most accounted for 76.4% and residents in apartment(having an elevator), least for 9.4%. 2. In the distribution of the recurring state in the distinction of the feature, the recurring group was more than the group of patients falling that ill at first as 62.2% and in the distinction of the feature of the recurring group, the recurring group turned high in case of men being from 50s to 60s years old or more, people living alone (divorce, separation by death, separation), students (joblessmen), people working in farming, stockbeeding, forestry, fisheries, a simple labour, graduates of a primary school I having the ability to decode the national language, the upper classes, people part two years since they begined to suffer arthritis, people who had members having ever experienced arthritis among families. 3. In the distribution of arthritis on the distinction of bodily pars, a knee articulation most accounted for 50.2% and the articulation of fingers, for 8.8%, wile the simultaneous, several parts (multiple) accounted for 35.1%. In the distinction of the feature, arthritis of a knee turned high in case of men being from 20s to 30s years old, unmarried persons, people having academic careers of university, the middle classes, residents in apartment (having stairs). In the dictnction of a feature the case of several parts (multiple) turned high in case of women being from 50s to 60s years old or more, people living alone (divorce, separation by death, separation), people having the ability to decode th. national language, the graduates of a primary school, the upper classes, residents in apartment (having elevator). 4. In the distribution of arthritis on e distinction of a contracting term, two years or more most accounted for 51.6% and the case of contacting from one year to two years, for 15.3%. Analysing the distinction of the feature, the case of two years or more turned high in case of women being from 50s to 60s years old or more, people living alone (divorce separation by death, separation), the upper classes, people having the ability to decode the national language, residents in apartment (having elevator). 5. In the distribution of an treatment institution before patients came to help, their not curing most accounted for 39.1%, general, orthopedic, neurological surgery (physical therapy), for. 20.0%, and th. therapy of Chinese medicine (acupuncture, moxacautery, Chinese medicine), for 17.5%, and a pharmacy (medical therapy), for 13.4%. The case of patients not curing, in the distinction of a feature, turned high in case of men 20s years old, unmarried, the lower classes, people having academic careers of university, residents in apartment (having elevator). 6. In e distribution of the extent of satisfaction with treatment, common most accounted for 54.4% and some satisfaction, for 32.8%. The case of common, in the distinction of a feature, turned high, in case of men living alone from 50s to 60s years old (divorce, separation by death, separation), married persons, the upper classes, people having academic careers of university, residents in independent house, residents in apartment (having elevator), 7. In the distribution of the degree of knowledge of the cause of arthritis, patients knowing that the cause is to use very much a articulation in normal times most accounts for 60.1%, and patients knowing the state of short nutrition as a cause, for 2.5%. The case of patients knowing that the cause is to use very much in normal times, in the distinction of a feature, turned high in·case of ment being 20s and 60s years old or more, unmarried persons, e lower classes, people having the ability to decode. the national language, people having academic careers of university, residents in apartment (having stairs), 8. In the distribution of the state of physical exercise before arthritis contracted, patients exercising very much on the whole most accpimend for 40.3%, and patients not exercising, for 34.7%. The case of patients exercising very much on the whole, in the distinction of the feature, turned high in case of men being from 50s to 60s years old or more, people living alone(divorce, separation by death, separation), the lower classes, people having the ability to decode the national language, graduates of a primary school, residents in apartment (having elevator). 9. In the taste of patients suffering from arthritis, while the group of patients falling that ill at first and the recurring group didn't smoke cigarets, during alcohol and coffee on the whole, and the group of patients falling once again that ill drank a cup of distilled linquor and three cup of coffee or more on the whole per one day, and the group of patients falling that ill at first liked sort of vegetables and the recurring group liked very much sons of vegetables and fresh and meat in their loving food normal times. 10. Analysing the distribution on the dining table used by patients and the structure of a powder room, at first, in the structure of a powder room, the group of patients filling that ill have a toilet stool using as their sits, and a Bush toilet on the whole, and the recurring group, a toilet stool using as their sits and conventional type, and in the structure of a dinning table, the group of patients falling that ill at first and the recurring group turned high, each as 66.9% and 6.3%, who have a dining table carring here and there. 11. In the distribution of patients of arthritis in relation to stress, the case that they feeled severly symptoms of arthritis when thay got stress, turned high, each, as 78.6% in the recurring poop, and the case not knowing, as 61.5% in the first group. In the extent of stress normal times, the case that they got much stress on the whole turned high, each, as 72.4% in e recurring group, and the care that got less stress on the whole, as 60.0%. 12. In the distribution on the distinction of symptoms and impedimental extent, the recurring group turned high in each variable. Analysing the feature of the recurring group, in the distinction of symptoms, the case that they fooled much that the node of an articulation is stiff, turned high, as 71.6, and in the distinction of treatment before. patients came to helpk, the theraphy of Chinese medicine (physical theraphy), as 84.4%, the theraphy of Chinese medicine (acupuncture, moxacautery, Chinese medicine), as 73.2%, and in the distinction of the satisfing extent on treatment, the case of comman, as 72.3%, and in the cause of arthritis, the case not recruiting their health after a birth, as 68.5%, and the case not recovering wholely an articulation having got hurt, as 62.8%, and in the state of physical exercise before they begined suffering from arthritis, the case exercising very much on the whole, (as 74.2%), and in the extent of subjective impediment, the case of not being able to act almost, as 66.7%, the case of acting but feeling some hard, as 66.3%. 13. The correlation in variables in relation to arthritis Analysing realted variables, the recurring frequency showed correlation with such as the extent that patients got stress normal times, and the exercising state before suffering arthritis, and showed contra-correlation with academic careers, the wights, coffee. The cigaret, e loving food of taste, showed corralation with the weight, stature, alcohole as the loving food of taste. On the basis of this result medical members of heal, who are related to the regular education, public education or development of this program, should be concerned to prevent orthris.

  • 연구 목적:ADHD 아동을 대상으로 DSM-Ⅳ 진단기준을 이용하여 세 아형으로 분류한 후, 임상적 특징과 신경심리학적 차이를 비교하고자 본 연구를 시행하였다. 방 법:연구는 1998년 7월부터 2001년 7월까지 주의력결핍 증상을 주소로 영남대학교 부속병원 정신과를 내원하여 ADHD로 진단된 6~15세 아동을 대상으로 하였고, 신경정신과적 공존질환이나 신경학적 이상이 있는 아동은 배제하여 총 404명으로부터 자료를 얻었다. DSM-Ⅳ 진단기준을 사용하여 아형으로 분류하였고, ADHD-C형이 234명(57.9%), ADHD-Ⅰ형이 156명(38.6%), ADHD-HI형이 14명(3.5%)이었다. 평균 연령은 9.63±2.49세였다. 약물치료 시작 전에, 정신병리평가, 지능 평가, 행동증상평가, 신경심리학적 실행기능에 대해 각각 평가를 하였다. 평가도구로는 정신병리를 평가하기 위해 한국아동인성검사(K-PIC)를, ADHD행동증상을 평가하기 위해 4종의 설문지형 평가도구인 한국판 주의력결핍장애 평가척도-가정판(ADDES-HV), ADD-H comprehensive teacher’s rating scale(ACTeRS), 한국형 소아기 집중력 문제척도(CAP)와 SNAP을 이용하였다. 지능은 K-ABC와 KEDI-WISC로 평가하였고, 주의력 및 실행기능검사는 Conner의 연속수행검사(CPT), 위스콘신분류검사(WCST), 정지신호검사(SST)를 사용하였다. 결 과:세 아형 별 비교에서 ADHD-C형이 가장 많았고 ADHD-Ⅰ, ADHD-HI 순 이었다. 아형간 남녀성별에 따른 유병율 차이는 보이지 않았다. 연령은 ADHD-Ⅰ형이 가장 높았다(p<.001). 정신병리평가에서 비행 과잉행동 정신증 점수는 ADHD-C형과 ADHD-HI형이 ADHD-Ⅰ형보다 높게 나타났고(p<.05), ADHD-C형에서 가족관계의 문제와 자폐증 점수가 ADHD-Ⅰ형보다 높게 나타났으며(p<.05), 자아탄력성 점수는 ADHD-Ⅰ형 보다 낮았다(p<.05). 불안, 우울, 신체화 증상은 세 아형간 차이를 보이지 않았다. 아형별 행동증상측정 결과 ADHD-C형이 ADHD-Ⅰ형보다 주의력결핍, 과잉행동, 충동성 점수가 더 높게 나타났다(p<.05). 단, 교사가 평가하는 ACTeRS에 의한 결과는 ADHD-HI형에서 주의력 결핍 증상과 과잉행동점수가 더 높았다(p<.05). 아형간 지능의 비교에서는 K-ABC를 이용한 평가에서 ADHD-HI 형이 순차처리항목과 계산능력에서 유의하게 높았고(p<.05), KEDI-WISC를 이용한 평가에서는 ADHD- HI형은 대상수가 소수여서 비교할 수 없었으며, ADHD-C형과 ADHD-Ⅰ형 사이에 유의한 차이는 보이지 않았다. CPT, WCST, SST를 이용한 신경심리학적 실행기능의 비교에서 아형간 계량적인 차이는 있었으나 통계적으로 유의한 차이는 보이지 않았다. 결 론:결론적으로 ADHD 세 아형은 임상적으로 뚜렷한 차이를 보였지만, 실행기능상 유의한 차이를 발견할 수 없었다. 향후 보다 잘 고안 된 연구와 발달중인 아동에 적절한 신경심리 평가 도구의 개발을 통해 결과를 보완해야 할 것으로 사료된다.

  • 1) 성기능장애 빈도는 정신분열병 환자군이 80%로 대조군 42%에 비해 유의하게 높았다(p<0.001). 성반응 주기에 따른 장애유형은 성적욕망장애 76%, 발기장애 75%, 발기유지장애 75%, 성적극치감의 질적감소 61%, 지루 50%, 사정시 정액량의 감소 44% 순서로 많았다. 성적극치감 횟수의 감소는 32%로 다른 장애유형에 비해 적었으며, 조루를 호소하는 경우도 15%나 되었다. 2) PRL 및 5-HT 측정치는 환자군에서 $28.5{\pm}20.6ng/ml$, $298.5{\pm}89.1ng/ml$으로서 대조군 $10{\pm}5.6ng/ml$, $169.2{\pm}37.8ng/ml$보다 유의하게 높았다(p<0.001). TST 측정치는 환자군이 $4.3{\pm}1.5ng/ml$, 대조군이 $4.5{\pm}1.2ng/ml$로 양군 모두 유의한 차이가 없었다. 3) 성기능장애를 증가시키는 변인은 결혼(미혼), 초발연령, 이병기간, 입원기간, 총약물투여기간 그리고 5-HT 측정치이었다. 특히 5-HT 비정상치군이 정상치군보다 성기능장애가 유의하게 높았다. 그러나 연령, 교육연한, 종교, 경제상태, PRL 및 TST 측정치, 항정신병약물용량, 약물역가, benztropine, ACSE, CGI, BPRS, PANSS, PANSS-CF, MMSE-K 점수와 성기능장애와는 무관하였다. 성기능장애는 정신분열병군에서 높았고, 성기능장애 유형별로는 성적욕망장애와 발기장애가 많았다. 미혼이거나, 초발연령이 높을수록, 질병에 이환된 기간이 길수록, 5-HT 농도가 높을수록 성기능장애가 증가하였다. 비록 혈중 5-HT 농도가 뇌 5-HT 활성을 어느정도 반영하는지는 알 수 없으나, 정신분열병 환자의 일차 병인인 과도한 5-HT 활성으로 인한 직접적인 성기능 억제효과 때문에 장애가 초래한다고 생각된다.
