Immunoadsorption for Treatment of Alzheimer's Disease

Efficacy of immunoadsorption for treatment of persons with Alzheimer dementia and agonistic autoantibodies against alpha1A-adrenoceptor.

The IMAD trial outlined aims to ascertain whether the positive effects of immunoadsorption (IA) on slowing down dementia progression, shown in a pilot trial, can be replicated in a slightly larger number of subjects and to comprehensively investigate the effects by a combination of brain and vessel imaging along with cognitive tests and further state-of-the-art cardiovascular, cerebrovascular and laboratory examinations. If the trial results underpin the hypothesis that IA effectively counteracts pathophysiological impairments and dementia-related cognitive decline, it may open up a new treatment approach against dementia, namely the reversal or avoidance of further vascular damage by the removal of agonistic autoantibodies (agAAB) in agAAB-positive persons. The aim of this study is (beside of safety) to demonstrate the stop of the vascular remodeling and cognition decline by immunoadsorption, a therapeutic method which is well established in cardiology and nephrology.
