ABSTRACT.We describe an infant who had epileptic apnea in the newborn period. Response to pain was decreased during the event. The corresponding electrographic phenomena were most marked over the left central and midtemporal regions. A CT scan showed findings compatible with a hemorrhagic infarction in the left temporoparietal region. The seizures responded to phenobar-bitone. The patient has remained seizure free and was neurode-velopmentally normal when assessed at 41 months of age.

摘要:

ABSTRACT.Although the Lennox-Gastaut syndrome can be generally defined as consisting of clinical seizures of different types, slow spike-and-wave complexes on the EEG, and mental retardation, the prognosis of the syndrome has been shown to depend on many variables. Most cases of Lennox-Gastaut syndrome have their onset in childhood, with nearly one-quarter developing from West syndrome. Patients with later onset of the syndrome appear to have less severe mental retardation and seizure disorders than those with early onset. Status epilepticus occurs frequently in patients with Lennox-Gastaut syndrome, and can lead to mental deterioration or death. Effective anticonvulsant therapy seems to reduce the severity of the seizures and the mental retardation. Younger patients tend to have primary generalized seizures of many types, whereas older patients have a higher incidence of complex partial seizures. This progression is reflected in the EEG abnormalities, with younger patients having slow spike-and-wave and older patients having focal abnormalities.

摘要:

ABSTRACT.While exploring the effects of mescaline in primates, Klüver and Bucy fortuitously discovered that placidity occurred after temporal lobectomy in the ferocious female rhesus monkey,“Aurora.”Elaboration on this in a series of three articles published between 1937 and 1939 eventually led to what is recognized today as the Klüver-Bucy syndrome (KBS). This syndrome is highlighted by inability to recognize objects visually (visual agnosia), hypermetamorphosia or loss of habituation to repetitive stimuli, eating disorders (bulimia), loss of normal fear and anger responses, and altered sexual behavior. Its equivalent in humans is further complicated with dementia, amnesia, and aphasia, and it has been encountered in association with many clinical conditions ranging from porphyria to adrenoleukodystrophy. KBS is currently understood as a disorder of cross-modal association due to interruption of the bidirectional amygdalocortical network mediated by opiate-containing fibers. KBS is of interest to epileptologists as a very exotic“ictal”variant. It may hypothetically result from inadvertent therapeutic removal of one epileptogenic temporal lobe in an individual harboring a contralateral, unrecognized, nonepi-leptogenic temporal dysfunction.At the time of their discovery, Klüver and Bucy were part of the historic“Neurology Club”of Chicago.

摘要:

ABSTRACT.Recent studies of factors affecting the P100 latency of the pattern visual evoked potential (PVEP) have questioned the earlier assumption that gender has a statistically significant effect. Guthkelch et al. (1987) reported that head size is an important variable. The question still remained as to what measurement of head size correlates with variation in P100 latency and how this variable should be used in clinical studies. The present study of 22 normal volunteers demonstrates that the transverse (preauricular notch to preauricular notch) head measurement is a major determinant of P100 latency. Gender and other head measurements were not found to make a statistical difference. Use of head-size-normalized data for clinical studies should improve both the sensitivity and specificity of the PVEP.

摘要:

ABSTRACT.This study was undertaken to assess the test-retest reliability of the Medilog SS-90-III Sleep Stager by comparing sleep stager scoring of the same records scored more than once. Nineteen normal volunteers, ranging in age from 19.3 to 63.5 (mean = 31.1 yrs), served as subjects. All sleep tapes were scored five consecutive times (runs 1–5). Sleep measures studied were: total time in bed; total sleep time; wake after sleep onset; movement time; time in stages 1, 2, 3, 4, and REM; percent of stages 1, 2, 3, 4, and REM; sleep latency; stage REM, 2, 3, and 4 latencies. The primary findings were: 1) Pearson correlation coefficients between consecutive scoring runs achieved an acceptable level of reliability (.990–1.00) for an automated scoring system in 51% of 100 correlations, whereas 49% were below .990, and 30% of the latter were below .970; 2) 13 of 20 alpha reliability coefficients of the same sleep measures reached the acceptable range of .990–1.00, and 7 (35%) of the alpha coefficients were below .990. The greatest problems occurred with the latency measures (sleep onset to stages REM, 2, 3, and 4), plus a second group: wake after sleep onset, movement time, and sleep latency. The only measures to show consistent reliability over .990 were total time in bed (based on clock time), and two measures of stages 3 and 4. No measures of stages REM or 2 showed consistent reliability over .900. Implications are discussed.
