The therapeutic goal in treating vascular dementia has been based on i
ts presumed association with cerebral arteriosclerosis. Therefore, it
is necessary to control risk factors for arteriosclerosis. In this con
nection, application of platelet-aggregating substances has been used
extensively, Promising results have also been observed by altering the
hemorheologic profile because hemorheologically active substances may
be able to ameliorate the course of vascular dementia. Further improv
ement could be achieved by application of the HELP system to enhance t
he effect of hemorheologically active drugs, Using the HELP system, LD
L, cholesterol, triglycerides and fibrinogen can be lowered considerab
ly and may result in clinical improvement or slowing of the progressio
n of vascular dementia.
