Scientists develop blood test for Alzheimer’s disease

Scientists have developed a blood test to diagnose Alzheimer’s disease without the want for costly intelligence imaging or a painful lumbar puncture, the place a sample of cerebrospinal fluid (CSF) is drawn from the lower back. If validated, the take a look at may want to allow faster diagnosis of the disease, which means healing procedures should be initiated earlier.

Current tips suggest detection of three awesome markers: odd accumulations of amyloid and tau proteins, as well as neurodegeneration the gradual and revolutionary loss of neuronal cells in precise regions of the brain.

However, a lumbar puncture can be painful and people may also trip complications or back ache after the procedure, whilst intelligence imaging is highly-priced and takes a long time to schedule.
