Most individuals are currently diagnosed with Alzheimer’s disease only after cognitive decline has set in and brain damage has become irreversible.

Alterations in brain metabolism and blood flow to the brain can be identified in the early stages of Alzheimer’s disease, before the onset of significant brain damage.

A recent study identified specific patterns of alterations in brain metabolism and cerebral blood flow in brain regions affected by Alzheimer’s disease, which could allow for earlier diagnosis.

Researchers have shown that brain imaging scans assessing alterations in metabolic activity and local blood supply in specific brain regions could potentially allow early diagnosis of Alzheimer’s disease (AD) before irreversible damage occurs, according to a study
