YaleNews said:

Yale researchers have tested a new method for directly measuring synaptic loss in individuals with Alzheimer’s disease. The method, which uses PET imaging technology to scan for a specific protein in the brain linked to synapses, has the potential to accelerate research for new Alzheimer’s treatments, the researchers said.

YaleNews said:

A decrease in synapses, the junctions between nerve cells, correlates with cognitive impairment in Alzheimer’s disease patients, they said.

YaleNews said:

The findings show that the non-invasive PET test can provide a direct measure of synaptic loss in adults with even mild cognitive impairment. “With this new biomarker, PET imaging for SV2A, we can measure synaptic density in the living human brain,” Chen noted.

This PET imaging tool is also being used in clinical research studies at Yale for other diseases of the brain where synapse loss is a critical component of the disease, said Richard Carson, co-author and director of Yale PET Center. These diseases include Parkinson’s disease, epilepsy, drug abuse, depression, and schizophrenia.
