[Thrombolysis in acute occlusion of cerebral blood vessels].

Thrombolysis may achieve recanalization in cases of occlusion of the cerebral vessels. If therapy is initiated in good time, development of cerebral infarction may be at least partially prevented. Thrombolytic treatment was performed in 14 patients at the Wagner-Jauregg Hospital within a period of one year. Urokinase was given locally, while rtPA was applied locally and/or systemically. 4 patients had an occlusion of the internal carotid artery, 6 an occlusion of the middle cerebral artery, and 4 an occlusion of the basilar artery. Complete recanalization was achieved in 6 patients, partial recanalization in 4, and no recanalization in 4. The neurological outcome of the cases with complete recanalization was good with the exception of one patients who died. Partial recanalization resulted in a fair outcome in 2 patients, while the other 2 died. 3 out of the 4 patients in whom no recanalization was achieved died. Our findings show that this form of therapy may considerably improve the natural history of the disease, provided recanalization is achieved in good time. They encourage us to continue this form of therapy and to work at improving the therapeutic criteria.

Recognition of matching tasks and stimulus novelty as a function of unilateral brain damage.

A 96-trial tachistoscope recognition task was given to 15 left-hemisphere-damaged, 12 right-hemisphere-damaged, and 30 non-brain-damaged subjects. Procedure called for a first stimulus presented for 250 msec, a 1-sec. pause, and a second stimulus for 250 msec. The stimuli were 12 animal drawings used in repeated series according to a random schedule. Six animals were familiar and six were novel. For half of the trials, the two pictures were of different animals. Size and position of the animal picture were controlled. Both reaction time and accuracy were independently scored. Judgments of same and different appear to function as if they are governed by different processes. For the control group, measures of same and different judgments do not correlate highly despite high internal consistency of subtests. Recognition of same becomes impaired with brain damage, but more so if the damage is rightsided. Recognition of different judgments shows considerably less sensitivity to the effects of unilateral brain damage.

The effect of unilateral brain damage on the appearance of question-induced CLEM reactions.

Three groups of subjects--34 non brain damaged, 15 left hemisphere damaged patients, and 15 right hemisphere damaged patients--were administered 40 questions facing the questioner while eye-movement following each question was recorded. 20 of the questions required subjects to indicate how many letters were in a given word. 20 questions tested their visuospatial capacity. The control group revealed a marked tendency to look to the left visual field regardless of the content of the question. The tendency to left-look or right-look, however, was not found to be related to education, age, length of hospitalization, the score on the "letters in a word" test, or the score on the visuospatial test. The left hemisphere damaged group performed remarkably like the control in that they too looked more to the left visual field than to the right. The right hemisphere damaged group, however, did not show a significant difference between left looking and right looking in response to both questionnaires. The findings were discussed in relation to the previous work of Kinsbourne (1972), and Gur, Gur and Harris (1975).
