Effects of a single dose of the acetylcholinesterase inhibitor velnacrine on recognition memory and regional cerebral blood flow in Alzheimer's disease.
The effects of a single oral dose of the acetylcholinesterase inhibitor velnacrine maleate on word and object recognition memory and regional uptake of 99mTc-exametazime were examined in patients with Alzheimer's disease. Word recognition memory was marginally improved 2 h after 75 mg velnacrine. With the same dose of velnacrine a relative increase in superior frontal uptake of 99mTc-exametazime was shown with single photon emission computed tomography (SPECT). This suggests increased regiona...Expand abstract
