New imaging technique in Alzheimer’s disease opens up possibilities for new drug development

October 3, 2016

Tau PET is a new and promising imaging method for Alzheimer's disease. A case study from Lund University in Sweden now confirms that tau PET images correspond to a higher degree to actual changes in the brain. According to the researchers behind the study, this increases opportunities for developing effective drugs.

There are several different methods of producing images showing the changes in the brain associated with Alzheimer's disease. The tau PET method reveals the presence of a protein in the brain, tau, with the help of a gamma camera and a specially selected radioactive molecule (F-AV-1451).

Tau has an important function in assisting the transport of various substances within the brain's nerve cells. People with Alzheimer's disease have raised levels of tau, leading to accumulation of the protein in the brain cells and gradually to cell death.
