[Long lasting psychotropic effects after long-term treatment with a hemoderivative]

Up to now there has been scarcely any publication of precise tests on the duration (lasting effect) of psychotropical effects which have appeared in brain activity after conclusion of a longterm therapy with vasoactive or metabolical substances. In 32 patients with symptoms of arteriosclerosis (average 72 years) a six weeks trial treatment was carried out with the haemoderivat Actihaemyl (6 weeks twice weekly 10 ml i.v.) according to the double blind method and checking the results with variance analysis. In the following mental areas positive effects have been proved: memory functions, creative behaviour, general psychophysical behaviour and in emotional, social and clinical behaviour. 12 weeks after conclusion of the therapy it was observed, that with the same test method there was a wide maintenance of the improvements in the psychical performance and this exceeded in many areas the status as observed immediately after conclusion of the therapy. The reason for this longterm effect of the haemoderivat which was under test is discussed.
