[Hypoperfusion of the brain in cardiac rhythm disorders].

In 134 patients (age 41-74 years) with symptoms of a transient ischaemic attack the authors made an ultrasonic dopplerometric examination of the main arteries of the head and a rheoencephalographic examination using the method of polygraphic recording with an ECG tracing II. st. 1.

[Central pontine myelinolysis].

The authors describe a case of central pontine myelinolysis in a 43-year-old female alcoholic, confirmed by post-mortem examination, as for technical reasons in lifetime neither CT nor MR examinations could be made. Despite the relatively scarce incidence of the disease, as mentioned in the literature, this possibility must be taken into consideration in particular in young alcoholics.

[Visual evoked potentials in chronic alcoholics].

In 25 chronic alcoholics (24 men, 1 women, mean age 45 years, mean period of abuse 26 years) the authors examined visual evoked potentials to stimulation by checkerboard pattern reversal. The results were compared with findings in a control group of 46 healthy subjects. An abnormal finding as regards the VEP was recorded in 28% of the alcoholics.
