[EEG in migraine].

The character and extent of EEG-changes in 40 patients with migraine accompagnée and 41 patients with classical migraine were studied and the EEG-diagnoses of both groups were compared. Moreover, the EEG-diagnoses in these patients were compared in relation to a control-group. The EEG showed pathological findings in 10 patients (83%) during the attacks and in 39 patients (57%) during the intervals with predominating focal changes (51%). Patients with migraine accompagnée had more frequently pathological findings (70%) as well as focal changes (60%) than patients with classical migraine (51% respectively 41%). The persistence of disturbances in patients with migraine accompagnée was longer than in patients with classical migraine. In comparison to the controls a significantly more frequent occurrence of pathological results was found in patients with migraine accompagnée and classical migraine during the attack as well as during the interval. The age of patients, duration of the migraine and frequency of attacks did not influence the extend of EEG changes. The EEG revealed in patients with migraine significantly more frequent functional disturbances than in controls, which were more pronounced in patients with migraine accompagnée and during the attacks.

[Headache and generalized epileptic EEG activity due to strong light exposure].

The case of a 16 years old girl with bilateral headache attacks and simultaneous generalised paroxysmal activity in EEG triggered by light is reported. Headache intensity as well as the number of generalised spike wave discharges under photic stimulation depended on intensity of light whereas wavelength of used light had no influence. Paroxysmal activity was most intensive at a flash light frequency of 25 Hz.

[EEG in multi-infarcts with and without intellectual deterioration].

The character and extent of changes in EEG in 124 patients with multiple infarctions, verified by CT, were reported. Further, the EEG diagnoses of patients with (55) or without (50) accompanying dementia were compared. In 19 patients the evidence of dementia could not be defined clearly. The EEG-diagnoses in these patients were compared with a group consisting of 41 patients with primary degenerative dementia (Alzheimer). The EEG showed pathological results in 89 patients with multiple infarctions and focal abnormalities were dominant. In 55 patients with symptoms of dementia and multiple infarctions significantly more pathological EEG-reports were present than in the other patients with multiple-infarcts and a significantly slower basic rhythm could be found. In patients with neurological deficits as compared to the group without neurological symptoms and multiple infarctions the pathological changes dominated significantly. The comparison between patients with multi-infarct-dementia and 41 patients with a senile dementia of the Alzheimer type only revealed a more frequent occurrence of focal abnormalities in patients with multi-infarct-dementia. However there was no significant difference between the number of normal and pathological EEGs.

[The value of EEG in subarachnoidal haemorrhagia].

The EEG findings from patients with subarachnoidal haemorrhage are described. The results of the EEG and CT are compared. Furthermore the influence of neurological deficits on the number and degree of pathological EEG results was investigated and the EEG of patients with and without intracranial aneurysm, shown by angiography, were correlated. The EEG was pathological in 47 patients (70%) predominantly with focal changes. In the 17 patients with intracranial lesions pathological EEG records were significantly commoner and the changes were more evident. Also in patients with neurological deficits pathological EEG were significantly more frequent. In 25 patients with aneurysm, proved by angiography, predominately focal changes were found which gave us information about the site of the aneurysm. It was shown, that the EEG gives informations about intracerebral lesions and that in cases with subarachnoidal haemorrhage functional disturbances can be seen. The EEG is also of prognostic value.

[The value of the EEG in patients with transient global amnesia (author's transl)].

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 value of EEG and computertomography in ischemic stroke (author's transl)].

35 patients with ischaemic cerebrovascular disease were investigated using EEG and computertomography on the same day and the results from both investigations were compared. The EEG was pathological in 27 cases of which 26 showed focal changes and one case generalised changes. In 8 patients the EEG was normal. The CT-results showed a hypodense lesion in 17 patients and multiple hypodense lesions in 3 patients. 13 cases had atrophy and a normal CT was present in 2 cases. In 26 patients the EEG and CT results were both pathological and in one case both normal. In the diagnosis of ischaemic cerebrovascular disease both of these noninvasive investigative techniques complement each other; CT demonstrating the morphology of a lesion whilst EEG shows more functional changes in the brain.
