Abstract
Doppler and real-time ultrasound (US) were performed to evaluate the extent of atherosclerotic changes in the carotid artery and to assess their relationship to prevalent cerebrovascular disease. Real-time US scans and Doppler measurements of the carotid arteries were analyzed in 5,201 subjects aged 65 years or older. Severity of atherosclerotic lesions was associated with increased frequencies of hyperechoic, irregular, and heterogeneous textured lesions (P < .0001). The severity of internal carotid artery stenosis was associated with thickening of the intima-media layer of the common carotid artery wall (r = .37, P < .0001). A history of stroke and transient ischemic attack (TIA) was more likely when hyperechoic, heterogeneous, and irregular lesions were seen in the carotid artery. Internal carotid artery stenosis correlated better with prevalent stroke and TIA than did sonographic descriptions of plaque texture. However, the prevalence of hyperechoic, heterogeneous, and irregular lesions increased as the degree of internal carotid stenosis increased. On real-time images alone, the average of the internal carotid artery maximal wall thickness is the sonographic measure of atherosclerosis that enables the best prediction of prevalent stroke and TIA.

Abstract
We compared clinical and radiologic features between 246 cardiac embolism (EMB) and 66 arterial embolic (tandem arterial pathology [TAP]) patients selected from the 1,273 patients with cerebral infarction in the Stroke Data Bank. Diagnostic definitions accounted for the increased frequency of cardiac disease among patients with EMB compared with TAP (78.4% versus 29.3%), while transient ischemic attacks (32.3% versus 13.1%) and carotid artery bruit (15.1% versus 3.3%) were more prevalent in TAP than in EMB. Multiple logistic regression differentiated TAP and EMB further. The probability of a TAP diagnosis was increased by the CT finding of a superficial infarct alone (odds ratio [OR] = 4.6; 95% CI = 1.5 to 13.7) or by a higher admission hematocrit. The probability of EMB was greater in patients with an initial decreased consciousness (OR = 39.2; 95% CI = 4.0 to 381.3) or with an abnormal first CT (OR = 3.2; 95% CI = 1.2 to 8.6). These findings indicate that the two infarct subtypes differ in the location and extent of the cortical infarction, which argues for a smaller particle size, with smaller and more distal infarction in embolism from an arterial source compared with cardiogenic embolism.

Abstract
For the 183 of 1276 patients in the NINDS Stroke Data Bank with convexity infarction in the middle cerebral artery territory, the size of the infarct did not differ between the two sides but the location of the main site of the infarct differed: on the left side, it was centred in the inferior parietal region, and was mid-frontal on the right. There was a good correlation between infarct size and weakness severity whether estimated by overall motor function on one side, arm, or hand alone. There was a poor correlation, however, for lesion location (lower third, middle third or upper third on either side of the Rolandic fissure) and any of the specific syndromes of focal weakness, no two cases sharing the same lesion for the same syndrome and several cases sharing the same lesion with a different syndrome. The findings indicated a difference in weakness syndromes between the two hemispheres and great individual variation of the acute syndrome caused by a given site of focal infarction along the Rolandic convexity. These variations may explain some of the difficulties showing effects of a given therapeutic agent in studies of acute ischaemic stroke. Large sample sizes will be required for the reliable assessment of any treatment using currently popular clinical stroke scales.

Abstract
OBJECTIVE To study the clinical features and causes of postoperative brainstem and cerebellar infarcts. METHODS Two groups were studied. The 10 group 1 patients had cardiac (eight) or aortic (two) surgery. The 12 group 2 patients had noncardiac-nonvascular surgery, including orthopedic (five), gynecologic (four), and general (three). Patients were studied by stroke services at university hospitals in Boston (13), Charlottesville (three), Baltimore (three), and Mainz (three) during 2 consecutive years. RESULTS Onset of strokes was immediately postoperative (six), during the first 48 postoperative hours (nine), and delayed 3 days or more (seven). Clinical syndromes were altered level of consciousness or cognition (15), vestibulocerebellar (four), and hemiparesis with focal brainstem signs (three). Infarction involved the brainstem (13), cerebellum (13), and posterior cerebral artery hemispheric territory (10). Causes: In group 1, five infarcts were due to cardiogenic embolism and three to embolism from the aorta. One patient had a postoperative pontine lacunar infarct and one developed an infarct in the territory of a known stenotic basilar artery. In group 2, one patient had vertebral artery injury from instrumentation, one had medical complications with severe hemorrhage and hypotension, and 10 most likely had position-related vertebral artery thromboses. CONCLUSIONS Patients with postoperative brainstem and cerebellar infarcts present with altered consciousness or vestibulocerebellar syndromes. The major cause of brain infarcts after cardiac surgery is embolism from the heart and aorta. The causes of infarction after general surgery are less clear, but neck positioning during or after surgery may play an important role by promoting thrombi in compressed arteries that later embolize intracranially when neck motion becomes free.

Abstract
OBJECTIVE This study was undertaken to test the reliability and validity of the Pathological Laughter and Crying Scale and the effectiveness of nortriptyline treatment for patients with emotional lability following stroke. METHOD Eighty-two patients with ischemic brain injury-54 who had been hospitalized with acute stroke and 28 others who requested treatment for pathological laughing and crying--were given standardized psychiatric and neurological assessments and then administered the Pathological Laughter and Crying Scale. The 54 acute stroke patients were used to evaluate the Pathological Laughter and Crying Scale, and the 28 patients with pathological emotional display were randomly assigned to nortriptyline treatment or placebo in a 6-week double-blind trial to assess the efficacy of a tricyclic antidepressant in treatment of this disorder. RESULTS The interrater reliability on the Pathological Laughter and Crying Scale for a subgroup of 15 patients was 0.93, and the test-retest reliability of the scale was excellent. After 4 and 6 weeks of treatment, scores on the Pathological Laughter and Crying Scale showed significantly greater improvement in the 14 patients given nortriptyline than in the 14 given placebo. Although almost one-half of these patients also had major depression, the improvement in emotional lability was independent of depression status. In addition, response to treatment was not significantly affected by lesion location or time since stroke. CONCLUSIONS The severity of symptoms in pathological emotional display can be reliably quantified with the Pathological Laughter and Crying Scale, and treatment with nortriptyline can effectively ameliorate this emotional disorder.

Abstract
A series of 309 admissions to a stroke unit was examined for anxiety symptoms. Patients were diagnosed with DSM-III-R generalized anxiety disorder (GAD) symptom criteria. They were divided into groups of no anxiety (59.2%), worried but not fulfilling GAD criteria (13.9%), and GAD (26.9%). Patients were then divided into depressed and nondepressed groups based on the existence of DSM-III major or minor (dysthymic) depression. These groups were not significantly different in their background characteristics, family or personal psychiatric history, social support or the severity of physical impairment. Anxiety plus depression was associated with left cortical lesions, whereas anxiety alone was associated with right hemisphere lesions. Patients with worry had anterior and patients with GAD had posterior right hemisphere lesions. These findings suggest that anxiety disorder (independent of depression) is not related to background characteristics or to severity of impairment but is, in part, influenced by the brain structures that are injured.

Abstract
To investigate a possible association of midline cerebral malformations with psychotic disorders, MRI and CT scans were blindly evaluated for 52 patients with schizophrenia, 9 with schizoaffective disease, and 79 consecutive nonpsychotic control subjects. Midline abnormalities were present in 10 of 61 patients (16.4%) versus 4 of 79 control subjects (5.1%; P < 0.05, chi-square). Of 52 schizophrenic patients, 8 had abnormalities of the septum pellucidum (SP): 5 had cavum vergae (CaV), 2 had cavum septum pellucidum (CaSP), and 1 had agenesis of the corpus callosum and SP. Of 9 schizoaffective patients, 2 had SP abnormalities: 1 CaV and 1 CaSP. Abnormalities of the SP, especially CaV, were significantly more frequent in women than in men (P < 0.02, chi-square).

Abstract
The frequency and correlates of the catastrophic reaction (CR) were examined in 52 consecutive patients with an acute stroke lesion. A new scale proved reliable for measuring the severity of CR. The CR was significantly associated with depression, a personal and family history of psychiatric disorder, and subcortical lesions, which were mostly located in the basal ganglia. Patients with and without a CR, when matched for the presence and type of depression, differed only in that CR patients had significantly more anterior lesions and a significantly higher frequency of subcortical damage. Results demonstrate that the CR is significantly associated with poststroke depression and may be a specific manifestation of certain types of poststroke depression.

Abstract
OBJECTIVE Depression has been linked to higher than expected mortality from natural causes, particularly among elderly patients with physical illness. The authors examined the effect of depression on mortality among a group of stroke patients followed up for 10 years. METHOD A consecutive series of 103 patients was assessed for major or dysthymic (minor) depression approximately 2 weeks after stroke with the use of a structured mental status examination and DSM-III diagnostic criteria. Vital status was determined for 91 of these patients 10 years later. RESULTS Forty-eight (53%) of the 91 patients had died. Patients with diagnoses of either major or minor depression were 3.4 times more likely to have died during the follow-up period than were nondepressed patients, and this relationship was independent of other measured risk factors such as age, sex, social class, type of stroke, lesion location, and level of social functioning. The mortality rate among depressed patients with few social contacts was especially high: over 90% had died. CONCLUSIONS These results indicate that depressed mood following stroke is associated with an increased risk of subsequent mortality. Patients who are depressed and socially isolated seem to be particularly vulnerable.

Abstract
BACKGROUND AND PURPOSE This article describes the prevalence of extracranial carotid atherosclerosis assessed by ultrasonography, its association with risk factors, and its relation to symptomatic coronary disease and stroke in men and women aged > or = 65 years. METHODS Maximum percent stenosis, maximum common carotid artery wall thickness, and maximum internal carotid artery wall thickness were assessed using duplex ultrasound in 5,201 men and women aged > or = 65 years in the Cardiovascular Health Study, a study of the risk factors and natural history of cardiovascular disease in the elderly. Existing coronary disease and stroke were assessed by physical examination and participant history. RESULTS Detectable carotid stenosis was present in 75% of men and 62% of women, although the prevalence of > or = 50% stenosis was low, 7% in men and 5% in women. Maximum stenosis and maximum wall thickness measurements increased with age and were uniformly greater at all ages in men than in women (p < 0.00001). Established risk factors for atherosclerosis (hypertension, smoking, diabetes) and indications of vascular disease (left ventricular hypertrophy, major electrocardiographic abnormality, bruits, and history of heart disease or stroke) related to all three carotid artery measures in the elderly. Of the three ultrasound measures, the best correlate for a history of coronary disease was maximum internal carotid artery wall thickness. For stroke the best correlate was common carotid artery wall thickness. Multiple logistic regression models of prevalent coronary heart disease and stroke that included the ultrasound findings indicated, after adjustment for age and sex, that maximum internal wall thickness and maximum common carotid wall thickness were significant correlates of both. Maximum stenosis did not add significantly to the correlation. CONCLUSIONS In the elderly the incidence of carotid atherosclerosis was high, although the frequency of severe disease was low. The prevalence and severity of carotid atherosclerosis continued to increase with age even in the late decades of life, and more disease was found in men than in women at all ages. Known risk factors for atherosclerosis continued to relate to carotid abnormalities in the later decades of life, both in symptomatic and asymptomatic subjects.

Abstract
BACKGROUND AND PURPOSE The lack of valid criteria for the clinical diagnosis of cardiogenic embolism is a major problem in both patient care and research. The aim of this study was to identify features on the initial computed tomogram of the brain that discriminate between patient groups with and without a cardiac source of embolism. To gain insight into the neuroradiological features relevant to the diagnosis of cardiac embolic stroke, we studied the initial computed tomogram of the 1,267 patients with ischemic stroke and such a scan in the National Institute of Neurological Disorders and Stroke (NINDS) Stroke Data Bank. METHODS We analyzed the initial computed tomographic data from 1,267 patients with ischemic stroke in the NINDS Stroke Data Bank. Based solely on the presence of cardiac sources of embolism, we defined groups with high (n = 244), medium (n = 165), and low (n = 858) risk for cardiogenic embolism and compared the features on the initial computed tomogram among these three groups. RESULTS Patients in the high-risk group were significantly more likely (p < 0.001) to have infarcts involving one half lobe or larger or infarcts involving both superficial and deep structures than patients in the medium- or low-risk groups. In contrast, deep small infarcts had a negative association (p = 0.004) with the presence of a cardiac source of embolism. There was no significant trend across risk groups in the percent with hemorrhagic infarction, regardless of whether patients with anticoagulant use at the time of the stroke were excluded. CONCLUSION Although some features of the initial computed tomogram had highly significant associations with the presence of a cardiac source of embolism, the predictive value of these features for an embolic source was low.

Abstract
BACKGROUND AND PURPOSE Psychological and biological hypotheses have been proposed to explain anosognosia. We correlated the presence of anosognosia with the presence and severity of psychiatric disturbances, neglect, intellectual impairments, and computed tomographic evidence of lesion size, location, and measurements of brain atrophy. METHODS A series of 80 patients with acute stroke were assessed using a battery of psychiatric and neuropsychological tests and computed tomography. RESULTS There were five main findings. First, 27 (28%) of the 96 patients originally screened showed anosognosia. Second, patients with anosognosia had significantly higher frequencies of hemispatial neglect and related phenomena, as well as deficits in recognizing facial emotions and in receptive prosody. Third, depression was equally frequent among patients with and without anosognosia. Fourth, patients with anosognosia had a significantly higher frequency of right hemisphere lesions, primarily involving the temporoparietal junction, thalamus, and basal ganglia. Fifth, patients with anosognosia showed significantly more subcortical brain atrophy, primarily involving the frontal white matter and diencephalic areas. CONCLUSIONS The present study demonstrates that anosognosia does not "protect" stroke patients from depressive feelings; rather, it represents arousal-attentional disorders after lesions in specific areas of the right hemisphere in nonaphasic patients with preexisting subcortical atrophy.

Abstract
BACKGROUND AND PURPOSE Our purpose was to describe and further understand the determinants of the time of onset of parenchymatous intracerebral hemorrhage and subarachnoid hemorrhage in patients enrolled in the Stroke Data Bank. METHODS We analyzed the observed times of onset of intracerebral hemorrhage (n = 237 patients) and subarachnoid hemorrhage (n = 243 patients) compared with expected times of onset if the probability of onset was constant across all time intervals. We also analyzed the role of clinical features (if any) in explaining the findings. RESULTS For intracerebral hemorrhage, 52.5% of patients reported onset times between 0600 hours and 1400 hours, with peak onset between 1000 and 1200 hours (chi 2 = 62.94, df = 11, p less than 0.001). Patients with subarachnoid hemorrhage were more likely to lack a history of hypertension compared with patients who had intracerebral hemorrhage (chi 2 = 23.3, df = 1, p less than 0.001). Patients with subarachnoid hemorrhage were more likely to have more uniform onset time throughout the day (chi 2 = 12.92, df = 7, p = 0.074). However, subarachnoid hemorrhage patients with a history of hypertension were more likely to have peak onset times in mid-to-late morning compared with patients without such a history (chi 2 = 35.25, df = 10, p less than 0.001). The nonuniformity of onset times for intracerebral hemorrhage persisted even if patients with unknown onset times were treated as through their onset times were randomly distributed between 0000 and 0800 hours. Seasonal periodicity and the relation between initial systolic or diastolic blood pressure and time of onset for either type of hemorrhage were not observed. CONCLUSIONS Our data suggest that the time of onset for both intracerebral hemorrhage and subarachnoid hemorrhage patients with a history of hypertension is similar to the diurnal variation in blood pressure.

Abstract
Thalamic strokes in 62 patients selected from the Stroke Data Bank were studied to determine differences among 18 infarctions (INF), 23 localized hemorrhages (ICH), and 21 hematomas with ventricular extension (IVH). Stupor or coma at onset occurred more frequently in the IVH (62%) than in the INF (6%) or ICH (13%) groups and was reflected in significantly lower median Glasgow Coma Scores in the IVH group (7) than in the INF (15) and ICH (14) groups. Although ocular movements were more frequently abnormal in the IVH group compared with the ICH and INF groups, no significant differences were found in the frequency of motor or sensory deficits. Among the 62 strokes, 32 had restricted lesions of the posterolateral (n = 9), anterior (n = 3), paramedian (n = 7), and dorsal (n = 13) portions of the thalamus. Differences in consciousness and in motor, sensory, and oculomotor deficits were found among the topographic subgroups. Stroke-related deaths occurred in 52% of IVH cases, 13% of ICH cases, and no cases of INF. Median lesion volume as detected with computed tomography was greater in hemorrhages (INF, 2 cm3; ICH, 10 cm3; IVH, 16 cm3), with mortality related to increasing hematoma size. Coma, Glasgow Coma Score lower than 9, weakness score greater than 15 of a possible 30, abnormal ocular movements, and fixed pupils were also associated with stroke-related mortality. We conclude that the initial neurologic syndrome does not discriminate infarcts from intrathalamic hemorrhages. Ventricular extension, however, causes significantly more severe deficits and higher mortality.

Abstract
BACKGROUND AND PURPOSE Hyperacute cerebral infarction trials require early differentiation of infarction subtype. Our aim was to determine clinical factors predictive of infarction subtype from data collected in the early hours of admission. METHODS Using the 1,273 patients enrolled in the Stroke Data Bank, stroke risk factors and demographic, clinical, and radiological features were compared between the 246 cardioembolic and 113 large-vessel atherosclerotic cerebral infarcts. RESULTS Stroke Data Bank definitions ensured more transient ischemic attacks in atherosclerotic infarcts and more cardiac disease in cardioembolic infarcts, but the diagnosis was distinguished further using a logistic regression model. Fractional arm weakness (shoulder different from hand) (odds ratio 3.1, 95% confidence interval [CI] 1.6-5.8), hypertension (odds ratio 2.8, CI 1.4-5.3), diabetes (odds ratio 2.5, CI 1.2-5.1) and male gender (odds ratio = 2.2, CI 1.2-4.1) occurred more frequently in patients with atherosclerotic than cardioembolic infarcts. Reduced consciousness (odds ratio = 3.2, CI 1.4-7.3) was more frequent in cardioembolism. For a male patient with hypertension, diabetes, and fractional arm weakness, the estimated odds of an atherosclerotic infarction were 47-fold that of a cardioembolic infarction. Patients with atherosclerotic infarcts were more likely to have a fractional arm weakness regardless of infarct size, whereas, for those with cardioembolic infarctions, fractional weakness was more frequent in infarcts less than 20 cc in volume. CONCLUSIONS Clinical features that are observed at stroke onset can help distinguish cerebral infarction subtypes and may allow for early stratification in therapeutic trials.

Abstract
To gain insight into neurologic signs relevant to the diagnosis of cardiogenic embolism, we analyzed data from 1,290 patients with cerebral infarcts in the NINDS Stroke Data Bank. Based solely on the presence of potential cardiac sources of embolism, we divided patients into groups of high (N = 250), medium (N = 167), and low (N = 873) risk of a cardiogenic mechanism for their stroke. Diminished level of consciousness was highly associated with the presence of a cardiac source of embolism. Of the four primarily cortical deficits assessed, three (visual field abnormalities, neglect, and aphasia) showed a highly significant graded relationship to the cardiac risk groups. For the fourth cortical deficit (other nonlanguage cognitive functions), this relationship did not attain statistical significance. Conversely, hemiparesis without sensory or cortical deficits had a strong inverse association to the presence of a cardiac source of embolism. This inverse association was weaker for sensorimotor strokes and nonexistent for pure sensory strokes. Although some neurologic findings had highly significant associations with the presence of a cardiac source of embolism, their predictive value for an embolic source was low.

Monoamine metabolites were measured in the cerebrospinal fluid (CSF) of depressed and nondepressed patients with acute stroke lesions and in nondepressed patients without stroke lesions. Depressed stroke patients had a significantly lower concentration of CSF 5-hydroxyindoleacetic acid (5-HIAA; a serotonin metabolite) than the other two groups. These findings suggest that poststroke depression may be mediated by serotonergic mechanisms.

Abstract
Of the 1,805 patients with acute stroke enrolled in the Stroke Data Bank, 237 had parenchymatous hemorrhage. After excluding 34 secondary intracerebral and 31 infratentorial hemorrhage patients, a logistic regression analysis of the 172 patients with primary supratentorial intracerebral hemorrhage (ICH) elucidated clinical factors that distinguished the 65 patients with lobar hemorrhage (LH) from the 107 patients with deep hemorrhage (DH) located in the basal ganglia and thalamus. In LH, severe headache was more common than in DH, while hypertension and motor deficit were significantly less common. Patients with either LH or DH had a similar prognosis and mean Glasgow Coma Scale (GCS) scores, despite the hematoma volume measured on the initial CT being significantly greater for LH than DH. The presence of intraventricular extension (IVH) was more frequent in DH. The frequency of IVH increased with hematoma volume in LH, but remained constant for DH. Two CT variables (IVH and hematoma volume) that differed in these two hemorrhage groups were important predictors of coma (GCS less than or equal to 8) in a logistic regression model. Differences in the frequency of IVH may help explain why the degree of impairment in consciousness was similar in the two groups. Among patients with supratentorial ICH, location of the hematoma is related to both volume and IVH, which are important determinants of the level of consciousness.

Abstract
OBJECTIVE Some investigators have suggested that major depression might be overdiagnosed in stroke patients because of changes in appetite, sleep, or sexual interest caused by their medical illness; others have suggested that depression may be underdiagnosed in stroke patients who deny symptoms of depression because of anosognosia, neglect, or aprosody. The authors' goal was to determine how frequently depressive symptoms occur in acute stroke patients with and without depressed mood to estimate how often diagnostic errors of inclusion or exclusion may be made. METHOD They examined the rate of autonomic and psychological symptoms of depression in 205 patients who were consecutively hospitalized for acute stroke. Eighty-five (41%) of these patients had depressed mood, and 120 (59%) had no mood disturbance. Forty-six (54%) of the 85 patients with depressed mood (22% of all patients) were assigned the DSM-III diagnosis of major depression. RESULTS The 120 patients without mood disturbance had a mean of one autonomic symptom, but the 85 patients with depressed mood had a mean of almost four. Tightening the diagnostic criteria to account for one more nonspecific autonomic symptom decreased the number of patients with major depression by only three; adding two more criteria decreased the number by only five. Thus, the rate of DSM-III major depression was 1% higher than the rate with one extra nonspecific autonomic symptom and 2% higher than the rate with two extra criteria. Conversely, loosening diagnostic criteria to account for denial of depressive illness increased the rate of major depression by only 5%. CONCLUSIONS Both autonomic and psychological depressive symptoms are strongly associated with depressed mood in acute stroke patients.

Abstract
Ischemic and hemorrhagic stroke frequently occur in temporal association with use or abuse of illicit and over-the-counter (OTC) sympathomimetic drugs. However, little information is available on the proportion of strokes associated with use/abuse of drugs in specific hospital populations. Between September 1, 1988, and August 1, 1989, 167 of 178 stroke patients entered into the Maryland Stroke Data Bank were asked for a history of drug use or abuse. Information was incomplete in 51 of 167 (31%) patients due to neurologic deficit or lack of inquiry. Eleven of the remaining 116 cases (9.5%) were historically associated with drug use. Age range was 25 to 56 years (mean, 41 years). Stroke associated with drug use occurred in four of 62 (6%) cerebral infarcts, two of 28 (7%) intracerebral hemorrhages, and five of 26 (19%) subarachnoid hemorrhages (p = ns). Drugs included cocaine in five (45%), OTC sympathomimetics in three (27%), phencyclidine in two (18%), and heroin in one (9%).

Abstract
While a relative preservation of repetition in acute transcortical aphasia (TA) has usually been associated with the functional integrity of the speech dominant (left) perisylvian area, recent amytal data (Bando et al., 1986) have suggested a fundamental role of the nondominant (right) hemisphere in language repetition. The neuroradiological correlates of repetition were studied in a consecutive series of 21 patients with acute TA. A similar frequency of either perisylvian or extraperisylvian pathology was found. In 2 patients with perisylvian pathology, the injection of amytal in the hemisphere contralateral to the lesion abolished repetition. Positron emission tomography (PET) in another patient revealed marked hypometabolism over the entire left cortical mantle ipsilateral to a basal ganglia lesion, suggesting that preserved repetition was carried out by right hemisphere structures. This was confirmed in a second patient with left extraperisylvian pathology, in whom a second lesion in the right hemisphere resulted in impaired repetition. These findings suggest that the spared contralateral hemisphere may subserve residual repetition in some transcortical aphasic patients with a lesion within or outside the speech-dominant perisylvian area.

Abstract
We report validation of a previously reported logistic regression model for predicting 30-day survival after supratentorial intracerebral hemorrhage using independent, prospectively collected data. The original model, using initial Glasgow Coma Scale score, hemorrhage size, and pulse pressure, accounted for mortality or survival at 30 days in 92% of patients in the Pilot Stroke Data Bank with a sensitivity of 0.84 and a specificity of 0.96. For external validation, the model was used to predict 30-day status for each patient in the Main Phase Stroke Data Bank for whom complete risk factor information was available. Overall, 90% of patients' outcomes were correctly predicted with a sensitivity of 0.85 and a specificity of 0.92. Two factors not collected in the Pilot Stroke Data Bank, hyperglycemia and intraventricular hemorrhage extension, were assessed to determine if they provided additional predictive information on 30-day mortality. Intraventricular hemorrhage extension contributed significant predictive information in a logistic regression, whereas hyperglycemia did not. The resulting four-factor model with an interaction term (intraventricular hemorrhage extension and Glasgow Coma Scale score) correctly classified the survival status of 94% of patients at 30 days. A more general outcome, death or failure to achieve a "good" Activities of Daily Living Score by one year, was analyzed with respect to the same four factors. The resulting model correctly classified 95% of the patients in the cohort.

Abstract
Patients with major depression admitted to hospital with acute stroke (n = 44), acute myocardial infarction (n = 25), or acute spinal cord injury (n = 12) were examined for differences in their phenomenological presentation of major depression. Depressed stroke patients were found to have significantly higher scores on the syndrome clusters for generalized anxiety and ideas of reference than depressed cardiac or spinal cord injury patients. In addition, significantly more stroke patients met diagnostic criteria for generalized anxiety disorder compared with the other two groups. Although spinal cord injury patients were younger, more likely to be treated with benzodiazepines, and less likely to be treated with beta-blockers, none of these factors distinguished stroke patients with anxious depression from stroke patients with depression only. These findings are consistent with the hypothesis that the etiology of depression following stroke may be different from that associated with myocardial infarction or spinal cord injury.

Abstract
In the Thrombolysis in Myocardial Infarction, Phase II pilot and clinical trial, 908 patients [326 (35.9%) in the pilot study and 582 (64.0%) in the randomized study] were treated with 150 mg recombinant tissue-type plasminogen (rt-PA) activator in combination with heparin and aspirin, and 3,016 patients [64 (2.1%) in the pilot study and 2,952 (97.9%) in the randomized study] were treated with 100 mg rt-PA in combination with heparin and aspirin. Adverse neurological events occurred in 23 patients treated with 150 mg rt-PA (2.5%) [nine cerebral infarctions (1.0%), 12 intracerebral hemorrhages (1.3%), and two subdural hematomas (0.2%)] and in 33 patients treated with 100 mg rt-PA (1.1%) [20 cerebral infarctions (0.7%), 11 intracerebral hemorrhages (0.4%), and two subdural hematomas (0.1%)]. The difference in adverse neurological events observed comparing the two rt-PA regimens was primarily due to a higher frequency of intracerebral bleeding among patients treated with 150 mg rt-PA (1.3% versus 0.4%, p less than 0.01). Patients with recent (within 6 months) histories of stroke were not eligible for the study, and patients with any history of cerebrovascular disease were declared ineligible early in the study. The small number of patients (89, or 2.3%) with any history of neurological disease, intermittent cerebral ischemic attacks, or stroke who were enrolled before the stricter eligibility criteria were imposed or on the basis of incomplete baseline information experienced an increased frequency of intracerebral hemorrhage compared with patients without such histories (3.4% versus 0.5%). Mortality at 6 weeks after presentation among 23 patients who had intracerebral hemorrhage was 47.8%. Intracerebral hemorrhage is a severe but infrequent complication of rt-PA therapy for acute myocardial infarction. The combined frequency of intracerebral hemorrhage, subdural hematoma, and cerebral infarction after treatment with 100 mg rt-PA is comparable to that observed in other trials with thrombolytic agents in acute myocardial infarction.

Abstract
The relationship between short-term memory impairment and sentence comprehension is explored in a right-handed patient with a focal temporoparietal lesion of the right hemisphere. The general clinical profile, as well as characteristics of the patient's immediate memory for word lists, suggests the occurrence of a 'mirror image' crossed aphasia. Detailed analysis of the patient's ability to repeat and to comprehend sentences, however, indicates some important differences between this case and previously reported patients with short-term memory impairment. It is suggested that these differences, which may be related to an unusual pattern of neuroanatomical organization of cognitive functions, involve symptom dissociations with implications for models of normal language/memory interactions.

Abstract
We prospectively studied stroke recurrence in 1,273 patients with ischemic stroke who were entered into the Stroke Data Bank. Median follow-up was 13 months. The 2-year cumulative recurrence rate among these patients was 14.1%. Age, sex, race, history of hypertension, atrial fibrillation, or transient ischemic attacks, and stroke location were not associated with a higher risk of stroke recurrence. Patients with an elevated blood pressure, an abnormal initial computed tomogram, or a history of diabetes mellitus were at a higher risk of stroke recurrence. In contrast, patients with an infarct of unknown cause were at a lower risk of stroke recurrence than patients with a defined stroke mechanism, such as lacune, embolism, or atherosclerosis. A multivariate model suggests that patients at the lowest risk for stroke recurrence have a low diastolic blood pressure, no history of stroke, no history of diabetes mellitus, and an infarct of unknown cause.

Abstract
Lacunar stroke was diagnosed in 337 (26%) of the 1,273 patients with cerebral infarction among the 1,805 total in the Stroke Data Bank. We analyzed the 316 patients with classic lacunar syndromes. Among these, 181 (57%) had pure motor hemiparesis, 63 (20%) sensorimotor syndrome, 33 (10%) ataxic hemiparesis, 21 (7%) pure sensory syndrome, and 18 (6%) dysarthria-clumsy hand syndrome. No striking differences were found among the risk factors for the lacunar subtypes, but differences were found between lacunar stroke as a group and other types of infarcts. Compared to 113 patients with large-vessel atherosclerotic infarction, those with lacunar stroke had fewer previous transient ischemic attacks and strokes. Compared to 246 with cardioembolic infarction, patients with lacunar stroke more frequently had hypertension and diabetes and less frequently had cardiac disease. We found a lesion in 35% of the lacunar stroke patients' computed tomograms, with most lesions located in the internal capsule and corona radiata. The mean infarct volume was greater in patients with pure motor hemiparesis or sensorimotor syndrome than in those with the other lacunar stroke subtypes. In patients with pure motor hemiparesis and infarcts in the posterior limb of the internal capsule, there was a correlation between lesion volume and hemiparesis severity except for the few whose infarct involved the lowest portion of the internal capsule; in these patients severe deficits occurred regardless of lesion volume. Taken together, the computed tomographic correlations with the syndromes of hemiparesis showed only slight support for the classical view of a homunculus in the internal capsule.

Abstract
The pattern of brain asymmetries was visualized on computed tomography (CT) scan in patients with a single acute cerebrovascular lesion. Patients were divided into those with typical or reversed frontal and/or occipital asymmetries. Among patients with a typical occipital asymmetry, those with left frontal or left basal ganglia lesions showed a significantly higher frequency of major depression and significantly higher depression scores than patients with similar lesion location but with reversed occipital asymmetry or those with a typical asymmetry and lesions in other (left or right) brain areas. Among patients with a reversed occipital asymmetry, there was no significant association between left frontal or left basal ganglia lesions and depression. This study demonstrates that the previously reported significant association between post-stroke major depression and lesion location is restricted to patients with a typical occipital asymmetry and is not present in patients with a reversed occipital asymmetry.

Abstract
The frequency of stroke among patients in six recent placebo-controlled trials of thrombolytic therapy for acute myocardial infarction is reviewed. Three trials used streptokinase and three used tissue plasminogen activator as the thrombolytic agent. While thrombolytic therapy greatly reduces the morbidity and mortality of acute myocardial infarction, it increases the rate of intracerebral hemorrhage.

We report 2 patients who developed a neglect syndrome, anosognosia, and major depression immediately after a right hemisphere cerebrovascular lesion. These cases demonstrate that neglect, anosognosia, and major depression may coexist in the same patient, and that the presence of anosognosia does not preclude the patient's recognition of emotional impairment.

Abstract
The impact of clinically diagnosed depression on recovery in activities of daily living over a 2-year follow-up was examined in a prospective study of 63 stroke patients. Although impairment in activities of daily living, neurologic diagnoses and findings, lesion location and volume as measured on computed tomographic scan, demographic variables, cognitive impairment, and social functioning were comparable between depressed (n = 25) and nondepressed (n = 38) patients during their acute hospitalization, the two groups had different patterns of recovery in activities of daily living. At 2 years after suffering a stroke, patients with an in-hospital diagnosis of depression (either major or minor depression) were significantly more impaired in both physical activities and language functioning than were non-depressed patients. Among patients with major depression, this disparity in the recovery profile was present even after the depression had remitted. This study emphasizes the need for early recognition and treatment of poststroke depression.

Abstract
We determined the prevalence of dementia in 927 patients with acute ischemic stroke aged greater than or equal to 60 years in the Stroke Data Bank cohort based on the examining neurologist's best judgment. Diagnostic agreement among examiners was 68% (kappa = 0.34). Of 726 testable patients, 116 (16%) were demented. Prevalence of dementia was related to age but not to sex, race, handedness, educational level, or employment status before the stroke. Previous stroke and previous myocardial infarction were related to prevalence of dementia although hypertension, diabetes mellitus, atrial fibrillation, and previous use of antithrombotic drugs were not. Prevalence of dementia was most frequent in patients with infarcts due to large-artery atherosclerosis and in those with infarcts of unknown cause. Computed tomographic findings related to prevalence of dementia included infarct number, infarct site, and cortical atrophy. Among 610 patients who were not demented at stroke onset, we used methods of survival analysis to determine the incidence of dementia occurring during the 2-year follow-up. Incidence of dementia was related to age but not sex. Based on logistic regression analysis, the probability of new-onset dementia at 1 year was 5.4% for a patient aged 60 years and 10.4% for a patient aged 90 years. With a multivariate proportional hazards model, the most important predictors of incidence of dementia were a previous stroke and the presence of cortical atrophy at stroke onset.

Abstract
We present a consecutive series of 8 patients who developed a manic episode after a brain injury. Five patients had cortical lesions (4 with damage to the right basotemporal region, and 1 with bilateral damage to the orbitofrontal area). While the other 3 patients had subcortical lesions (white matter of the right frontal lobe, right anterior limb of the internal capsule, and right head of the caudate), a fluorodeoxyglucose positron emission tomography scan showed hypometabolism in the right lateral basotemporal region in all 3 patients. These findings suggest a major role for the basal region of the right temporal lobe in the modulation of mood.

Abstract
The interaction between anxiety disorder and major depressive disorder in patients with cerebrovascular lesions was examined in a controlled, 2 x 2 study design. A consecutive series of 24 patients who met criteria for major depression only were compared with 6 patients who met criteria for both major depression and generalized anxiety disorder, and 45 patients who did not meet criteria for either major depression of generalized anxiety. Among patients with positive computed tomographic scans, the anxious-depressed group (n = 19) showed a significantly higher frequency of cortical lesions, while patients with major depression only (n = 15) had a significantly higher frequency of subcortical (basal ganglia) strokes. No significant between-group differences were found in other variables, such as demographic variables, familial and personal history of psychiatric disorders, and neurologic deficits. These findings suggest that, in this mostly black, low-socioeconomic-status population, cortical vs subcortical lesion location may play an important role in determining whether severe anxiety occurs in patients with post-stroke major depression.

Abstract
To gain insight into the historical features relevant to the diagnosis of cardiac embolic strokes, we studied the 1,290 patients with cerebral infarcts in the NINCDS Stroke Data Bank. Based solely on the presence of cardiac sources of embolism, we divided the patients into groups of high (n = 250), medium (n = 166), and low (n = 874) risk of a cardiogenic mechanism for their stroke. There was a highly significant graded relationship between increasing risk of a cardiac source and a history, or presence of, systemic embolism, abrupt onset, and diminished level of consciousness at onset. These clinical features may be useful for assessing the likelihood of a cardiac embolic mechanism in patients with cerebral infarcts.

Abstract
We studied 1,273 patients with ischemic cerebral infarction who were entered into the Stroke Data Bank, a prospective, observational study involving four university hospitals and the Biometry and Field Studies Branch of the National Institute of Neurological Disorders and Stroke. Forty patients had noniatrogenic recurrent stroke within 30 days after the index cerebral infarction. Using life tables, the 30-day cumulative +/- SE risk of early recurrence for all infarctions was 3.3 +/- 0.4%. The risk of early recurrence was greatest for atherothrombotic infarction (7.9 +/- 2.2%, eight of 113 patients) and least for lacunar infarction (2.2 +/- 1.2%, eight of 337 patients). Both cardioembolic infarction (4.3 +/- 0.9%, 10 of 246 patients) and infarction of undetermined cause (3.0 +/- 0.5%, 14 of 508 patients) had intermediate risks. History of hypertension and diabetes mellitus, as well as diastolic hypertension and elevated blood sugar concentration at admission, were associated with early recurrence. Logistic regression analysis estimated the risk of early recurrence to be 8.56% in those with coexisting hypertension and a glucose concentration of 300 mg/dl versus 0.77% in the absence of these two abnormalities. Early recurrence was associated with longer median duration of initial hospital stay (27 vs. 14 days) and a higher 30-day case-fatality rate (20% vs. 7.4%). Increased weakness scores were associated with early recurrent stroke. Identification of the determinants of early recurrent stroke may lead to better secondary prevention and may help select high-risk patients for further study.

Abstract
Ninety-three patients with acute stroke lesions restricted to the right hemisphere were examined for the presence of mood changes. While 46 patients showed no mood changes, 19 were unduly cheerful, 17 had developed major depression, and 11 had developed minor depression. Although there were no significant between-groups differences in other demographic variables, neurological deficits, activities of daily living, cognitive impairment, or quality of social support, patients with major depression had a significantly higher frequency of familial history of psychiatric disorder and lesions of the parietal cortex than patients with either no mood change or major depression following left-hemisphere lesions. On the other hand, undue cheerfulness was significantly associated with lesions of the right frontal operculum. These findings suggest that major depression following right-hemisphere lesions may have a different aetiology and mechanism than major depression following left frontal or basal ganglia lesions.

Abstract
In a group of stroke patients with left-hemisphere lesions, those with major depression performed significantly below nondepressed patients on four of nine cognitive domains examined with a neuropsychological test battery. Among patients with right-hemisphere stroke, those with major depression did not perform below nondepressed patients on any of the nine cognitive domains. The differential effect of depression on cognitive performance between left- and right-hemisphere lesion groups could not be accounted for by demographic variables, neurological symptoms, lesion location, or lesion size. Poststroke major depression appeared to produce a decline in cognitive performance or dementia of depression that depended on the laterality of the lesion.

Abstract
The time of onset of ischemic stroke was determined for 1,167 of 1,273 patients during the collection of data by four academic hospital centers between June 30, 1983, and June 30, 1986. More strokes occurred in awake patients from 10:00 AM to noon than during any other 2-hour interval. The incidence of stroke onset declined steadily during the remainder of the day and early evening. The onset of stroke is least likely to occur in the late evening, before midnight.

Abstract
In a prospective study of 1,805 hospitalized patients in the Stroke Data Bank of the National Institute of Neurological and Communicative Disorders and Stroke, the 1,273 with infarction were classified into diagnostic subtypes. Diagnosis was based on the clinical history, examination, and laboratory tests including computed tomography, noninvasive vascular imaging, and where safe and relevant, angiography. Five hundred and eight cases (fully 40%) were labeled as infarcts of undetermined cause (IUC), of which 138 (27%) were evaluated with both computed tomography and angiography. The clinical syndrome and computed tomographic and angiographic findings in 91 (65.9%) of these 138 IUC cases were clearly not attributable to large-artery thrombosis and could permit reclassification of the infarct as due to some form of embolism. Failure to define a source of embolus kept them in the category of IUC. Thirty-one cases (22.5%) could be reclassified as due to stenosis or thrombosis of a large artery, and 16 (11.6%) as lacunar infarction. To determine if those selected for angiography among the IUC patients differed from those with other final diagnoses, a stepwise multiple logistic model was used. The most important characteristics were young age, presence of a superficial infarct, prior transient ischemic attack, low weakness score, and presentation with a nonlacunar syndrome. The results of the model suggest that angiography use was determined by clinical characteristics uniformly across centers and not by final diagnosis. Continued use of the category IUC may help clarify risk factors and stroke subtypes, allow new mechanisms of ischemic stroke to be uncovered, and prevent classification categories of stroke used in clinical trials from becoming too broad.

Abstract
Both opiate agonist and antagonist injection have been reported to modulate prolactin secretion, alter brain excitability and produce seizures, and modify the postictal state. We studied the effects of administration of high-dose naloxone, an opiate antagonist, on postictal prolactin levels, seizure duration, and postictal behavior, using patients undergoing electroconvulsive therapy (ECT) as a seizure model. Seven patients had 8 mg naloxone injected prior to one ECT treatment and saline injected prior to another treatment, with the order of injection randomized. Before ECT and 15 min after ECT, prolactin levels were drawn, and no blunting of the expected postictal prolactin elevation by naloxone injection was observed. We found no evidence that endogenous opiates trigger prolactin secretion during seizures. Seizure duration was also similar in saline and naloxone groups, and naloxone did not reverse postictal depression, as has been reported in an animal model.

Abstract
We followed 16 patients who developed depression immediately after a stroke for 6 months. By that time, six patients showed no depression (recovered group), while 10 patients were still depressed (nonrecovered group). There were no significant differences in demographic variables and social functioning between the groups, but the nonrecovered group showed less improvement in cognitive function and more physical impairments. Patients in the nonrecovered group had mainly cortical lesions, while those in the recovered group had mainly subcortical and posterior circulation strokes.

Abstract
Previous brain infarctions seen on CT are common in the absence of history of stroke. Eleven percent of patients (135/1,203) without stroke history had ischemic lesions on their first CT, unrelated to the presenting stroke. Stroke Data Bank files were reviewed to determine whether the occurrence, location, and CT characteristics of those lesions are associated with their undetected status. Two distinct patterns were seen: (1) Small lesions of 1 cm or less were left hemisphere predominant and involved the deep structures of the brain; the majority of these were clinically silent. (2) Lesions greater than 1 cm occurred more frequently in the right hemisphere and were mostly superficial; these infarcts produced signs unrecognized by the patient or family. Risk factors for silent stroke were similar to those for stroke in general. Frequencies of in-hospital complications and 30-day fatality rates from the presenting stroke were not influenced by the existence of a prior silent stroke.
