Luria-Nebraska Neuropsychological Battery performance of brain dysfunctional patients with positive or negative findings on current neurological examination.
Two experiments were conducted to investigate the effects of positive or negative neurological examination results on performance on the Luria-Nebraska Neuropsychological Battery in a sample of 229 patients with a history of proven brain damage. The groups did not differ on demographic variables of age, education, or disorder chronicity. The positive and negative neurological examination groups were highly differentiable. A second study demonstrated additional high subgroup differentiability within the positive and negative neurological examination groups as a function of the degree of cognitive deficit demonstrated on the neuropsychological measure. Implications of the results were discussed.

The clinical utility of computed tomographic scanning and neurologic examination in the management of patients with minor head injuries.
The evaluation and management of patients with minor head injury (MHI: history of loss of consciousness or posttraumatic amnesia and a GCS score greater than 12) remain controversial. Recommendations vary from routine admission without computed tomographic (CT) scanning to mandatory CT scanning and admission to CT scanning without admission for selected patients. Previous reports examining this issue have included patients with associated non-CNS injuries who confound the interpretation of the data and affect outcome. We hypothesized that patients with MHI and no other reason for admission with normal neurologic examinations and normal CT scans would have a negligible risk of neurologic deterioration requiring surgical intervention. To validate this hypothesis we studied 2766 patients with an isolated MHI admitted to seven trauma centers between January 1, 1988, and December 31, 1991. There were 1898 male patients and 868 female patients; injury was blunt in 99%. A neurologic examination and a CT scan were performed on 2166 patients; 933 patients had normal neurologic examinations and normal CT scans and none required craniotomy; 1170 patients had normal CT scans and none required craniotomy; 2112 patients had normal neurologic examinations and 59 required craniotomy. The sensitivity of the CT scan was 100%, with positive predictive value of 10%, negative predictive value of 100%, and specificity of 51%. The use of CT alone as a diagnostic modality would have saved 3924 hospital days, including 814 ICU days, and $1,509,012 in hospital charges. Based on these data, we believe that CT scanning is essential in the management of patients with MHI and that if the neurologic examination is normal and the scan is negative patients can be safely discharged from the emergency room.

Brain CT-scanning and neurological examination in small cell bronchogenic carcinoma.
A brain CT-scan and a neurological examination were performed on forty-nine consecutive patients with small cell bronchogenic carcinoma before the start of chemotherapy and every three months thereafter. Contrast-enhancement was used in 90% of the CT-scans. Ninety percent of the neurologic examinations were performed by the same neurologist. No prophylactic cranial irradiation was given, and cranial irradiation was withheld if a CT-scan indicated metastases, unless the patient was symptomatic. Thirty-five patients are evaluable including 34 with a brain autopsy. CNS-metastases were found in 18 patients. Two of them had not been examined within three months of autopsy and are excluded from the calculations of diagnostic accuracy. Of the remaining 16 patients 10 had a correct diagnosis of cerebral metastases made by CT-scan, while the neurologist made 11 correct diagnoses of CNS-metastases. Seventeen patients did not have CNS-metastases including one patient alive and free of disease. Fifteen and 11 were judged to be free of metastases by the CT-scan and the neurologist, respectively. Two patients with negative autopsies had positive CT-scans turning negative at subsequent examinations. Two had positive CT-scans which became negative and at autopsy CNS-metastases were located at different sites from those initially indicated by CT. The positive predictive value of CT-scan was 71%, while the negative predictive value was 71%. In conclusion, routine CT-scan and neurological examination are equally sensitive but have low yields when there is no clinical suspicion of CNS-metastases. The predictive value of CT-scanning could possibly be higher with the newer generations of equipment.

End-stage Alzheimer's disease. Glasgow Coma Scale and the neurologic examination.
OBJECTIVE: To characterize the cognitive and neurologic features of patients with end-stage Alzheimer's disease using a standard neurologic examination and the Glasgow Coma Scale. DESIGN: Case series. SETTING: Local community nursing homes. PATIENTS: Forty patients with Alzheimer's disease were drawn from previously enrolled subjects in the Rochester Alzheimer's Disease Project with Clinical Dementia Rating scores of 3, 4, or 5. MAIN OUTCOME MEASURES: Scores on the Glasgow Coma Scale and cognitive screening examinations and the prevalence of neurologic manifestations such as primitive reflexes and extrapyramidal signs were compared across the Clinical Dementia Rating groups. RESULTS: When compared with patients in the Clinical Dementia Rating stages 3 and 4, patients with a stage 5 scored significantly lower on the Glasgow Coma Scale, with the discriminating subscales being verbal and motor responses. Primitive reflexes, myoclonus, and dyskinesia were increasingly prevalent in the more terminal stages. Cognitive screening assessments did not discriminate between groups. CONCLUSIONS: Rudimentary neurologic functions can be readily assessed and, when viewed together with the Glasgow Coma Scale, may circumvent the "floor effect" frequently encountered when using the currently available cognitive and functional scales and, thereby, better define patients with end-stage Alzheimer's disease.

Usefulness of neurological examination for diagnosis of the affected level in patients with cervical compressive myelopathy: prospective comparative study with radiological evaluation.
OBJECT: Although neurological examination is the key step to reaching a correct diagnosis of cervical compressive myelopathy (CCM), the accuracy of diagnosis of the affected spinal level for CCM has not yet been tested. METHODS: The authors conducted a prospective study to elucidate how accurately the affected intervertebral level can be determined and decompressed based on neurological examination. Fifty patients who underwent successful decompressive surgery for cervical myelopathy caused by single-level disc herniation or spondylosis were included in this study (38 men and 12 women, mean age 60 years). Three board-certified spine surgeons participated in establishing the neurological diagnoses. One of the three surgeons made a diagnosis of CCM, and the other two conducted the neurological examination including deep tendon reflex, pinprick response, muscle weakness, and numbness in the hand only, knowing that the patient had CCM, and established the neurological-level diagnosis. A single intervertebral level responsible for patient's symptoms was determined concordantly based on magnetic resonance imaging and myelography findings by two spine surgeons, and this served as the standard. Agreement between neurological and neuroimaging/radiological level diagnoses was determined. The rate of agreement between neurological and neuroimaging diagnosis was 66%. Among the neurological tests, patient-perceived location of numbness in the hands was the most useful for establishing the affected level. For the other three tests the agreement rate was lower than 50% and thus each individual test may not be reliable for diagnosing the affected level. CONCLUSIONS: The results of this study suggested that neurological examination in patients with CCM is moderately accurate and reliable for determining the neurological level of disease.

Neurologic examination in infants with hypoxic-ischemic encephalopathy at age 9 to 14 months: use of optimality scores and correlation with magnetic resonance imaging findings.
OBJECTIVES: To evaluate whether a structured and scorable neurologic examination (The Hammersmith Infant Neurological Examination) correlates with early magnetic resonance imaging findings in a group of infants with hypoxic-ischemic encephalopathy (HIE) and whether the scores of this assessment can predict the locomotor function in these children. STUDY DESIGN: A total of 53 term infants fulfilling the criteria for HIE underwent scanning within 4 weeks from delivery with a 1 Tesla HPQ magnet. The scores from the neurologic examination performed between 9 to 14 months were correlated to the neonatal magnetic resonance imaging findings and to the maximal locomotor function defined at the ages of 2 and 4 years. RESULTS: The scores were always optimal in the infants with normal or minor neonatal magnetic resonance imaging findings. The lowest scores were associated with severe basal ganglia and white matter lesions. All the infants who had a global score between 67 and 78 at 1 year were able to walk independently at 2 years and without restrictions at 4 years. Scores between 40 and 67 were associated with restricted mobility and scores <40 with severely limited self-mobility at 2 and 4 years. CONCLUSIONS: The use of a standardized neurologic optimality scoring system gives additional prognostic information, easily available in the clinic, on the severity of the functional motor outcome in infants with HIE.

Which better predicts later outcome in full-term infants: quality of general movements or neurological examination?
The qualitative assessment of general movements (GMs) has been shown to be a better predictor of neurological outcome than the traditional neurological examination in brain-damaged preterm infants. The aim of this study was to compare the results of the two techniques in term infants. Off-line assessment of GMs from videorecordings and neurological examinations were carried out, from birth till about 6 months of postterm age, in a group of 58 term infants, the majority of which were affected by mild to severe hypoxic-ischaemic encephalopathy. The agreement between the two techniques and their predictive power, with respect to the neurological outcome at 2 years, were evaluated for four age groups. The range of agreement between neurological and GM findings was between 78 and 83%. At all ages the results of GM observation correlated highly with the neurological outcome; their sensitivity and specificity with respect to outcome were consistently slightly superior to those of neurological examination. In infants normalize after an initial period of transient abnormalities, GMs normalize earlier than the neurological results.

Are neurologic examination abnormalities heritable? A preliminary study.
BACKGROUND: Neurologic examination abnormalities (NEA) are more prevalent among patients with schizophrenia as well as their unaffected relatives when compared with healthy controls, suggesting that NEA may be endophenotypes for schizophrenia. We estimated the heritability of NEA in moderately sized pedigrees. We also evaluated correlations between NEA and cognitive performance in order to examine their construct validity. METHODS: Members of eight extended families, each consisting of two first degree relatives with schizophrenia/schizoaffective disorders, as well as available first- to fifth-degree relatives were examined (n=96 participants). A modification of the Neurological Evaluation Scale (NES) was employed, augmented with localizing signs. Where feasible, we used untransformed data such as error counts and completion time, rather than ordinal measures. Heritability was estimated using the variance component method, implemented in SOLAR. RESULTS: Statistically significant heritability (h2) estimates were obtained for several measures (p<0.05, h2+/-standard error: rapid alternating movements, right-sided completion time, 0.99+/-0.19; alternating fist-palm test, completion time, 0.77+/-0.19 s, errors, 0.70+/-0.32; fist-ring test, right-sided completion time, 0.53+/-0.23 s, left-sided completion time, 0.70+/-0.21 s; go-no go task, correct responses, 0.93+/-0.33; audio-visual integration, correct responses, 0.79+/-0.54). For most items, heritability analysis was hampered by insufficient data variability (infrequent errors). Correlational analyses show some degree of divergence among types of NEA, repetitive motor tasks being associated with most domains of cognitive functioning other than executive functioning, and cognitive-perceptual tasks being associated with memory and executive functioning. CONCLUSIONS: Significant familial influences on certain aspects of neurologic performance were detected. These heritable measures were also correlated with heritable neurocognitive measures.

Correlation between neurological examination and behavioural assessment of the newborn infant.
A modified Prechtl neurological examination and the Brazelton Neonatal Behavioural Assessment Scale (BNBAS) were used on days 1 and 5 in 78 healthy newborn infants. Correlations between variables in the neurological examination and the behavioural items and subscales in the BNBAS were calculated. Especially the total neurological score and optimality score were significantly correlated to motor performance (days 1 and 5) and to orienting responses to animate and inanimate stimuli (day 1) in the BNBAS. The neurological variables showed poor or no correlation to the habituation items and to certain items concerned with changes of behavioural state in the BNBAS.

The relative roles of neurological examination, functional abilities, and computed tomography in the definition of treatment failure in patients with anaplastic gliomas.
Forty-one patients with anaplastic gliomas undergoing postoperative treatment and evaluation underwent bimonthly evaluation of the following indices of treatment failure: neurological examination; Karnofsky functional rating; and computed tomography (CT) brain scanning. Treatment failure was declared when neurological examination or Karnofsky rating showed increased impairment or when CT scan revealed an increase in tumor sizes. Most often, all three indices simultaneously indicated treatment failure. In only 6 of 41 cases the CT scan alone was the first indication of treatment failure. During the first 6 months of follow-up, tumor enlargement on CT scan as a sole index of treatment failure occurred in only 3 of 26 cases that showed evidence of treatment failure during that time. For patients with glioblastoma, about 6% of treatment failures within 6 months are predicted to be missed by Karnofsky rating plus neurological examination, whereas CT scan alone is predicted to miss about 30%. It would seem reasonable to rely on the neurological examination and Karnofsky rating for follow-up during the first 6 months after surgery, without routine serial CT scanning during that time.

[School achievement and neurologic examination: a 7-years' correlation study].
Neurological examination and school performance were analyzed in 146 children from a longitudinal follow up on growth and development at northern metropolitan Santiago, Chile. Their reading and writing abilities and their performance on neuro-maturational tests at the third elementary grade, were compared with academic achievements seven years later and highly significant correspondence was found among these terms. Reading comprehension and simple arithmetic problem solving abilities were the most affected aspects in children that exhibited multiple subtle neurological abnormal signs. Writing and design abilities were also involved up to a certain degree. Intellectual endowment was a determinant factor in this relationship since children above average. I.Q. showed less neurological involvement and better academic qualifications and vice versa. Subjects with many subnormal neuro-maturational signs had relative under-ratings at school examinations, whichsoever their mental level was. Thirty percent of the initial 208 study case were missed in the 7 year time span: Most of them were unable to read and write properly at third elementary school grade, showed evidence of several minor neurological failures and abandoned school in the mean time. By contrast, 96% of the index group could be reexamined. This bias implies that between early learning plus neurological status, at age 9 years and the later academic performance should have been an extremely positive interrelationship for the whole series.

Computed tomography brain scanning in alcohol withdrawal seizures. Value of the neurologic examination.
We evaluated the usefulness of computed tomography (CT) brain scanning in alcoholic patients with withdrawal seizures (n = 151) and other neurologic problems (n = 87) and compared the findings of a detailed neurologic examination to the results of CT scanning. In patients with seizures, nearly 50% of CT scans were normal, 34% showed generalized cerebral atrophy, and only 15% showed focal structural lesions. When focal neurologic deficits were present, 30% of CT scans showed focal structural lesions compared to 6% when such deficits were absent (p less than 0.0002). The frequency of potentially reversible lesions was 18% in patients with and 1% in patients without focal neurologic deficits (p less than 0.0002). Of patients treated surgically, 9% had focal neurologic deficits and 1% did not (p less than 0.03). Results were similar in alcoholic patients with other neurologic problems. Careful use of the neurologic examination adequately determines which patients need prompt CT scanning. In the absence of either focal deficits on neurologic examination or signs of acute head trauma, CT brain scanning does not improve the evaluation of patients with alcohol withdrawal seizures.

An evidence-based approach to predicting low IQ in very preterm infants from the neurological examination: outcome data from the indomethacin Indomethacin Intraventricular Hemorrhage Prevention Trial.
We evaluated whether the degree of cerebral palsy (CP) at age 3 in very preterm children is predictive of full-scale intelligence quotient (FSIQ) <70 at age 8 by calculating likelihood ratios (LRs) for findings on the neurologic examination. Data from the follow-up phase of the Indomethacin Intraventricular Hemorrhage Prevention Trial, which includes periodic neurologic examination and neuropsychometric testing, were used. Information was available on 366 of 440 (83%) children with birth weight of 600 to 1250 g who survived. Neurologic examination at age 3 was grouped by presence and type of CP, and the Weschler Intelligence Scale for Children-Third Edition FSIQ at age 8 was grouped dichotomously (<70 or > or =70). CP was identified in 35 of 366 3-year-olds (9.5%). An FSIQ <70 was identified in 47 of 366 children at 8 years old (12.8%). FSIQ <70 occurred in 14 of 17 children with tri- or quadriplegia (82%), 8 of 18 children with di- or hemiplegia (44%), and 25 of 331 children without CP (7.5%). Useful LRs were calculated for tri- or quadriplegia (30), di- or hemiplegia (5.7), and children without CP (0.55). These LRs have greater impact on posttest odds for FSIQ <70 than those for birth weight <1000 g, history of bronchopulmonary dysplasia, and Stanford-Binet Intelligence Score <70 at age 3. We conclude that the neurologic examination at 3 years old predicts FSIQ <70 at age 8 with LRs that allow evidence-based parental counseling and intervention planning.
