OBJECTIVE Changes in cerebral function were evaluated in patients with Alzheimer disease treated or not with plasmapheresis with Human Albumin Grifols 5%. Sequential brain single photon emission computerized tomography (SPECT) and magnetic resonance imaging techniques were used. METHODS Brain SPECT (99mTc-ECD) studies were obtained at baseline (double headed gammacamera Siemens Ecam, LE-HR, 30 sec/image/3 degrees, 128 x 128). Studies were quantified by means of SPM (Statistical Parametric Mapping) and Neurogam. Changes between baseline and after a follow-up period of up to 12 months were evaluated in patients undergoing or not the plasma exchange treatment program. All the studies were double blinded and referenced to a normal age-matched database. Comparisons were performed individually and between groups: treated (plasma exchange) versus non treated group, and baseline versus post follow-up analysis. CONCLUSIONS Significant differences in the areas of Brodmann were observed between the treated and the control groups and after the follow-up period. Regarding the hippocampal uptake, significant differences were observed between the treated and the control groups. Together with the clinical findings, these preliminary results provide biological evidence to the hypothesis that plasmapheresis with Human Albumin Grifols 5% can play a role in the treatment of Alzheimer's disease.

UI	MeSH Term	Description	Entries
D008279	Magnetic Resonance Imaging	Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.

D001921	Brain	The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.	Encephalon

D002986	Clinical Trials as Topic	Works about pre-planned studies of the safety, efficacy, or optimum dosage schedule (if appropriate) of one or more diagnostic, therapeutic, or prophylactic drugs, devices, or techniques selected according to predetermined criteria of eligibility and observed for predefined evidence of favorable and unfavorable effects. This concept includes clinical trials conducted both in the U.S. and in other countries.	Clinical Trial as Topic

D000544	Alzheimer Disease	A degenerative disease of the BRAIN characterized by the insidious onset of DEMENTIA. Impairment of MEMORY, judgment, attention span, and problem solving skills are followed by severe APRAXIAS and a global loss of cognitive abilities. The condition primarily occurs after age 60, and is marked pathologically by severe cortical atrophy and the triad of SENILE PLAQUES; NEUROFIBRILLARY TANGLES; and NEUROPIL THREADS.
