The influence of intravenous tinofedrine (0.12 to 0.17 mg/kg body-weight) on cerebral blood flow has been investigated in 23 patients (mean age 65 years) with subacute cerebral infarction. The mean cerebral blood flow increased significantly by 20% in the infarcted hemisphere during a treatment period of 12 days. Clinically an improvement of an initially depressed vigilance level was established which was quantified psychopathometrically in 4 patients.
Nine cases with temporal fossa arachnoid cysts were diagnosed by computerized tomography (CT). Five patients also had subdural hematomas, three of them following head trauma. When the hematoma was chronic and of equal hypodensity with the cyst, a clear-cut differentiation was not possible from the CT scan. The presence of a subdural hematoma could only be suggested by thickened arachnoid structures crossing the hypodense area, indicating the wall between cyst and hematoma. The cyst could often be diagnosed by bulging of the skull bone and a temporal lobe defect. Differences in density between cyst and hematoma, such as in subacute subdural hematoma, delineated both entities. Typical examples are demonstrated. Treatment consisted of evacuation of the hematoma and excision of the cyst in all cases.
The EEG findings from 30 patients with transient global amnesia (TGA) of vascular origin are described. A pathological result was seen in 18 cases, from which 17 had predominantly focal changes. 12 EEG's were normal. With increasing time interval between the TGA and the EEG investigation a normal record was slightly commoner. 20 patients had CT results, of which 8 cases were pathological. In 12 cases the EEG and CT results were correspondingly pathological or normal. The EEG shows functional disturbances even after the neurological deficits have resolved, which are related to transient metabolic or diminished blood-flow disturbances, but do not result in structural lesions to bae seen in the CT.
The frequency of irreversible induced PA (IPA) by ADP or EN has been studied in 246 stroke patients. Compared to an age and sex matched control group IPA was more frequent in patients with CVD. Eighty six patients were referred to treatment of IPA with ASA or pentoxifylline or both compounds as combined treatment. ASA as well as PO were found to satisfactorily influence IPA however, the best therapeutic results have been achieved by combined treatment.
In 55 patients with acute or subacute CVD a beneficial but dose dependent effect of PO on human blood rheologic properties has been demonstrated, indicated by a lowering of blood viscosity, a decrease of fibrinogen concentration and inhibition of PA.

This report presents an evaluation of prognosis in 227 patients with subarachnoid haemorrhage caused by intracranial aneurysm, comparing operative treatment in 118 patients with conservative treatment in 109. In all operable cases, the prognosis following early surgery was better than that of conservative treatment. Statistical comparison of patient groups according to the clinical condition allowed the formation of guidelines for the optimal timing of surgery: patients in good clinical condition should be operated on at the earliest possible moment. The overall mortality with such a policy is lower than with a waiting policy, since the majority of recurrences occurred within 2 weeks. Patients with disturbed consciousness and neurological deficit are best operated on either within 24 hours or following stabilization or improvement of the clinical picture -- mostly after 2 weeks. The risk of rebleeding is much lower in these cases, which justifies awaiting optimum clinical conditions. Surgery on comatose patients is contraindicated.
In 55 patients with posttraumatic epilepsy there was evidence of pathologic computertomographic findings in 76.4% and of pathologic EEG findings in 83.6% of the patients. On the contrary focal neurological signs have been detected in only 13 patients (23.6%). In 8 of these patients neurological symptomatology correlated well with pathologic findings.
83 patients with a transient ischemic attack have been investigated by computerized tomography. 71 patients had symptoms in the region of the middle cerebral artery, 12 in the basilar region. In 14 patients a hypodense lesion in the CT was found. Two of those patients showed multiple lesions. Two of those patients showed multiple lesions. The lesion affected always the region of the middle cerebral artery. Atrophy mostly of minimal degree was diagnosed in 31 patients.

Report on a series of patients suffering from cerebrovascular insufficiency caused by stenosis and/or occlusion of one or several major cerebral vessels. The patients were divided in two groups, one being medically treated with anticoagulants, the other operated on either a carotid artery thrombosis by thromboendarterectomy or occlusion treated with an extracranial-intracranial arterial bypass. Results after a follow-up period of 1-3 years are compared and discussed in view of the recent literature.
Computer tomography investigations in 72 children with epilepsy showed 42 to be normal and 30 abnormal. An abnormal scan was more common children with partial seizures and in the presence of neurological deficits and/or mental retardation.
We tried to show the attitude of the environment towards the epileptic patient with special consideration of teachers and the mother of the epileptic child. specific problems of the epileptic patient like frequency of convulsions, psychiatric manifestations and the disease process itself were viewed in relationship to the ability to work and the position in school. We looked in addition into legal problems like fitness to drive, delinquency and insurance problems.
