Overview

What is he best known for?

The fields of study he is best known for:

  • Internal medicine
  • Disease
  • Cognition

Boo Johansson mostly deals with Dementia, Immune system, Immunology, Gerontology and Longitudinal study. His Dementia research is multidisciplinary, relying on both Twin study, Age of onset, Alzheimer's disease and Risk factor. His work carried out in the field of Immune system brings together such families of science as Interleukin 6 and Senescence.

His study looks at the intersection of Immunology and topics like Physiology with Risk profile, Age and gender and Mortality rate. His Gerontology study combines topics in areas such as Body mass index, Cross-sectional study, Affect and Vascular dementia. His Longitudinal study study integrates concerns from other disciplines, such as Congenital cytomegalovirus infection, Multivariate analysis and Lymphocyte.

His most cited work include:

  • Role of Genes and Environments for Explaining Alzheimer Disease (988 citations)
  • Substantial genetic influence on cognitive abilities in twins 80 or more years old (606 citations)
  • Longitudinal Studies of Clonally Expanded CD8 T Cells Reveal a Repertoire Shrinkage Predicting Mortality and an Increased Number of Dysfunctional Cytomegalovirus-Specific T Cells in the Very Elderly (376 citations)

What are the main themes of his work throughout his whole career to date?

The scientist’s investigation covers issues in Cognition, Dementia, Gerontology, Developmental psychology and Cognitive decline. Boo Johansson has researched Cognition in several fields, including Longitudinal study, Demography and Association. Within one scientific family, Boo Johansson focuses on topics pertaining to CD8 under Longitudinal study, and may sometimes address concerns connected to T cell.

Immune system and Immunology are inextricably linked to his T cell research. His Dementia research is multidisciplinary, incorporating elements of Twin study, Psychiatry, Alzheimer's disease and Clinical psychology. His studies examine the connections between Gerontology and genetics, as well as such issues in Activities of daily living, with regards to Psychosocial.

He most often published in these fields:

  • Cognition (33.55%)
  • Dementia (31.31%)
  • Gerontology (31.63%)

What were the highlights of his more recent work (between 2017-2021)?

  • Cognition (33.55%)
  • Gerontology (31.63%)
  • Dementia (31.31%)

In recent papers he was focusing on the following fields of study:

His primary areas of investigation include Cognition, Gerontology, Dementia, Clinical psychology and Life satisfaction. His studies deal with areas such as Demography, Association, Confounding and Cognitive decline as well as Cognition. His Gerontology research is multidisciplinary, incorporating perspectives in Epidemiology, Population study, Public health, Cognitive aging and Cognitive reserve.

His Dementia research is under the purview of Disease. His Clinical psychology research incorporates elements of Neuroticism, Subjective memory, Cognitive impairment, Cognitive skill and Depressive symptoms. His study in Life satisfaction is interdisciplinary in nature, drawing from both Social support and Microeconomics.

Between 2017 and 2021, his most popular works were:

  • The Gothenburg H70 Birth cohort study 2014–16: design, methods and study population (31 citations)
  • Sleep disturbances and dementia risk: A multicenter study (30 citations)
  • Transitions across cognitive states and death among older adults in relation to education: A multistate survival model using data from six longitudinal studies. (19 citations)

In his most recent research, the most cited papers focused on:

  • Internal medicine
  • Disease
  • Cognition

Boo Johansson mainly focuses on Cognition, Dementia, Gerontology, Social psychology and Developmental psychology. The concepts of his Cognition study are interwoven with issues in Bivariate analysis, Interaction, Demography and Confounding. His Dementia research includes themes of Insomnia, Sleep in non-human animals, Clinical psychology, Prospective cohort study and Neurology.

The Gerontology study combines topics in areas such as Physical fitness, Public health, Response rate, Family history and Depression. Many of his research projects under Social psychology are closely connected to Work motivation and Job performance with Work motivation and Job performance, tying the diverse disciplines of science together. Boo Johansson combines subjects such as Transition and Replication with his study of Developmental psychology.
