Objective

To evaluate characteristics of cognitive impairments according to the location of aneurysmal subarachnoid hemorrhage (SAH) using a computerized neuropsychological test (CNT).

Method

A total of 211 patients were transferred to our rehabilitation department after becoming neurologically stable following aneurysmal SAH. Twenty four of the 211 patients met the inclusion criteria and participated in a screening test using the mini-mental state examination (MMSE). Twenty patients with a MMSE score <26 were followed prospectively with a CNT and Beck depression inventory (BDI). Eleven patients had anterior communicating artery (ACoA) aneurysms and the other 9 had middle cerebral, internal carotid or posterior communicating artery aneurysms.

Results

There were no differences in age, education, Hunt and Hess grade, or Fisher grade between the patients with ACoA aneurysmal SAH compared to patients with other aneurysmal SAH. In patients with ACoA aneurysmal SAH, scores of BDI (p=0.020), verbal learning test were lower than those of other aneurysmal SAH patients. In contrast, patients with non-ACoA aneurysmal SAH took significantly more time in auditory (p=0.025) and visual continuous performance tests (p=0.028). The cognitive deficit following aneurysmal SAH could be characterized by its location using CNT.

Conclusion

Using CNT in aneurysmal SAH patients could be a useful tool for evaluating the characteristics of cognitive impairment and planning rehabilitation programs according to each characteristic.

Relationship between the Severity of Poststroke Depression (PSD) and Cognitive Function in the Patients with Stroke.: Yoo, Seung Don , Chun, Min Ho , Pyun, Sung Bom; J Korean Acad Rehabil Med 2009;33(5):527-532.

Abstract

Objective
To investigate the correlation between poststroke depression (PSD) and the cognitive impairment in the patients with subacute stroke. Method: The subjects were 53 patients with cerebral infarction (n=28) and cerebral hemorrhage (n=25). These patients had a mean age of 64.3. The mean onset time was 2.7 months. The location of stroke was in the right hemisphere in 24 subjects, left hemisphere in 23, and bilateral in 6. The severity of PSD was evaluated by Beck Depression Inventory (BDI), Korean Geriatric Depression Scale (KGDS), and Hamilton Rating Scale for Depression (HRS-D) and the evaluation of cognitive impairments was based on Computerized Neuro-psychological Test (CNT), Mini-Mental State Examination (MMSE). The Pearson correlation was used as a measure of the strength of association between cognitive impairments and PSD. Independent t-tests were calculated to compare differences in cognitive functioning according to hemispheric involvement. Results: PSD was diagnosed in 33 of 53 patients by the BDI, in 28 of 43 patients by the KGDS and in 22 of 45 patients by the HRS-D. Scores in the verbal and visual learning domains of the CNT were significantly correlated with scores on the BDI, KGDS, and HRS-D, but scores on the MMSE were unrelated to any of these measures of depression. Conclusion: We suggest the use of the CNT in poststroke depression patients could be a useful tool from the viewpoint of differentiation of PSD patients with or without cognitive impairment and the diagnosis for poststroke depression should be conducted by self rating and objective assessments.

Usefulness of 1H Magnetic Resonance Spectroscopy for Evaluation of Cognitive Impairment after Subarachnoid Hemorrhage Caused by Rupture of Middle Cerebral Artery Aneurysm.: Kang, Si Hyun , Chun, Min Ho , Na, Hyo Jin , Kim, Sang Tae; J Korean Acad Rehabil Med 2007;31(5):516-520.

Objective
To investigate the relationship between cognitive impairment and 1H magnetic resonance spectroscopy (1H MR spectroscopy) in patients with subarachnoid hemorrhage (SAH) caused by rupture of middle cerebral artery (MCA) aneurysm. Method: 1H MR spectroscopy was performed in 6 patients with SAH after rupture of MCA aneurysm and in 20 controls. Image-guided localized 1H MR spectra were obtained from left parietal white matter (PWM). The cognitive status was evaluated using the Mini Mental Status Examination (MMSE), and the scores were correlated with N- acetyl aspartate/creatine (NAA/Cr), choline/creatine (Cho/ Cr), and myoinositol/creatine (mI/Cr) metabolic ratios. Results: NAA/Cr was significantly lower, and Cho/Cr was higher in SAH patients than in controls in the left PWM (p＜0.05). NAA/Cr in the left PWM was correlated with MMSE (p＜0.05), but Cho/Cr and mI/Cr in the left PWM was not correlated with MMSE (p＞0.05). Conclusion: 1H MR spectroscopy could be helpful in the evaluation of cognitive impairment in SAH. (J Korean Acad Rehab Med 2007; 31: 516-520)
