What is 'Infectious Madness' about?

Infectious Madness is a book by science journalist Harriet A. Washington that explores the possible relationship between infectious diseases and mental disorders. Drawing on scientific research, the author examines how certain pathogens might influence conditions such as depression, anxiety, obsessive-compulsive disorder, and schizophrenia. It is a popular science book that invites reflection on the links between physical and mental health, and has garnered interest in both the medical field and among the general public.

How might infections affect mental health?

Some research suggests that certain bacteria and viruses could have the ability to affect the brain, either by crossing the blood-brain barrier or by triggering autoimmune responses. For example, it has been proposed that group A streptococcus might be associated with PANDAS syndrome, which includes symptoms such as tics and obsessive behaviors in children. Likewise, a possible connection between influenza and an increased risk of certain psychiatric disorders in adulthood has been studied. However, these are research hypotheses and are not definitive. The scientific community continues to explore these links, and the book presents an overview of the most relevant findings to date.

Key pathogens highlighted in the book

Washington dedicates chapters to various pathogens that have been studied in relation to mental health. These include the Epstein-Barr virus, which has been linked to chronic fatigue and possible mood alterations; the parasite Toxoplasma gondii, which has been associated with behavioral changes in some studies; and the bacterium Borrelia burgdorferi, which causes Lyme disease and can present neuropsychiatric symptoms. In all cases, the author emphasizes that these are observational correlations and that more research is needed to establish causality.
