Objectives:The purpose of this study is to evaluate the clinical applicability of cognitive evoked potentials (CEPs) to identify the cognitive disorder in cerebrovascular diseases (CVD). Methods:The P3 latencies, amplitudes and latency to amplitude ratios (LARs) of CEPs were measured in 25 healthy controls and 35 patients with CVD. The association of CEPs with variables including age, sex, Mini-Mental State Examination (MMSE), CVD types, loci of hemiplegic limbs, duration, education, Brief Psychiatric Rating Scale (BPRS), and Instrumental Activities of Daily Living (IADL) were also analyzed. Results:1) The P3 latencies (447.87±113.06 msec) and LARs (65.83±43.25) were prolonged in CVD (p<0.01), while the amplitudes (8.18±2.51 μV) were not changed. 2) The P3 latencies (537.31±101.14 msec) and LARs (94.89±46.44) in CVD with MMSE <24 were prolonged, and the amplitudes (6.45±1.98 μV) were reduced significantly (p<0.01, respectively), as compared with those in CVD with MMSE≥24 (363.39±19.67 msec, 38.40± 8.37 and 9.81±1.76 μV, respectively). 3) The BPRS and IADL in CVD with MMSE<24 were significantly (p<0.01) different from those in CVD with MMSE≥24. 4) On analyzing the association of CEPs with variables in CVD, the P3 latencies were correlated positively with age, BPRS and IADL, while negatively with MMSE and DLFA. The amplitudes were correlated positively with MMSE, while negatively with age, BPRS and IADL. The LARs were correlated positively with age, BPRS and IADL, while negatively with MMSE. 5) On analyzing the association of CEPs with variables in CVD with MMSE≥24, the P3 latencies were correlated positively with age, while negatively with MMSE. The amplitudes and LARs were not correlated with variables. 6) On analyzing the association of CEPs with variables in CVD with MMSE<24, the P3 latencies were correlated positively with BPRS, while negatively with MMSE. The amplitudes were positively correlated with age. The LARs were positively correlated with IADL. Conclusions:The P3 latencies and LARs of cognitive evoked potentials seemed to a useful clinical measures to assess cognitive disorders in CVD.

Objectives:To identify changes in blood markers of oxidative stress among dementic and healthy aged persons, and to compare levels of peripheral markers of oxidative stress between dementia of the Alzheimer's type (DAT) and vascular dementia (VD), and finally to analyze factors affecting those. Design:Some antioxidants had been known to reduce the risk of dementia, while increase of 4-hydroxy-nonenal and decrease of heme oxygenase in DAT had been reported. Recently increased free radical activities were also found in VD. Therefore, this study was tried to search for a blood markers to discriminate DAT and VD. Materials and Methods:The blood levels of total antioxidant capacity (TAC) and catalase activity of 50 patients with DAT and 50 patients with VD were compared with those of 56 healthy aged controls. In addition, variables including risk factors of dementia, degree of dementia measured by MMSE, Hasegawa Dementia Scale, GDS and CDR, and activities of daily living were also assessed. Results:1) The levels of TAC were significantly (p<0.01) lower in dementia than normal aged controls (1.47±0.08 mmol/L), while the catalase activities were significantly (p<0.01) higher in dementia than normal aged controls (45.61±11.67 kU/L). 2) The TAC levels were significantly (p<0.01) lower while the catalase significantly (p<0.01) higher in DAT (1.24±0.09 mmol/L, 133.42±58.45 kU/L respectively) than VD (1.31±0.08mmol/L, 81.33±24.65 kU/L respectively). 3) The TAC and catalase activities were significantly (p<0.01) correlated with duration of dementia, behavior symptoms, activities of daily living, and the severity of dementia. Conclusions:Peripheral blood markers of oxidative stress were significantly different in dementia from normal aged controls. Furthermore, the difference was more severe in DAT than VD, which means the effect of oxidative stress is more in DAT than in VD. Therefore, they might be clinically useful to assess and discriminate dementia.

단지양 근위축증(Monomelic Amyorophy) 3례 : 증례 보고 Case Report
김기찬,정호중,정상욱,정흥채,조근열 고신대학교 의학부 1999 高神大學校 醫學部 論文集 Vol.14 No.1-2
Monomelic amyotrophy is a rare form of motor neuron disease which is insidious onset in the second and fourth decades, male preponderance, sporadic occurrence, wasting and weakness confined to one limb, and absence of involvement of the cranial nerves, cerebrum, brain, stem, and sensory system. Symptoms and signs often progress for several years before spontaneously arresting. Neurologic findings and electrophysiologic studies are only useful for the diagnosis of monomelic amyotrophy and other laboratory testing are frequently normal or nonspecific. We reported three cases of typical monomelic amyotrophy with review of the articles.
