Kaj Blennow is affiliated with the University of Gothenburg in Sweden. Their research primarily falls within the broader field of Medicine, with notable subfields including Physiology, Psychiatry and Mental Health, Neurology, Molecular Biology, and Cognitive Neuroscience.

The scientist's work extensively covers topics related to Alzheimer's disease research and treatments, dementia and cognitive impairment research, as well as neuroinflammation and neurodegeneration mechanisms. Other notable research interests include advanced neuroimaging techniques and applications, traumatic brain injury and neurovascular disturbances, functional brain connectivity studies, and investigations into S100 proteins and annexins.

Blennow has contributed to publications in several scientific venues, with the most frequent including:

  • Alzheimer s & Dementia
  • Alzheimer s Research & Therapy
  • Neurology
  • Brain
  • Alzheimer s & Dementia Diagnosis Assessment & Disease Monitoring

Frequent coauthors in Blennow's research include Henrik Zetterberg, Nicholas J. Ashton, Thomas K. Karikari, and Oskar Hansson.

Significant recent papers by Blennow include:

  • The Amyloid-β Pathway in Alzheimer's Disease, 2021, Molecular Psychiatry
  • Discriminative Accuracy of Plasma Phospho-tau217 for Alzheimer Disease vs Other Neurodegenerative Disorders, 2020, JAMA
  • Blood phosphorylated tau 181 as a biomarker for Alzheimer's disease: a diagnostic performance and prediction modelling study using data from four prospective cohorts, 2020, The Lancet Neurology
  • Plasma P-tau181 in Alzheimer's disease: relationship to other biomarkers, differential diagnosis, neuropathology and longitudinal progression to Alzheimer's dementia, 2020, Nature Medicine
  • A genome-wide association study with 1,126,563 individuals identifies new risk loci for Alzheimer's disease, 2021, Nature Genetics

Kaj Blennow was awarded the Nordic Medical Prize by the SalusAnsvar/Ulf Nilsonnes Foundation for Medical Research in 2017.
