This summary provides the key details from the annotated bibliography in 3 sentences:
The annotated bibliography describes a longitudinal study that explored the role of the Borna Disease Virus in psychiatric patients over 21 years by measuring antibodies against the virus in patient samples. The study found that patients with advanced schizophrenia had higher levels of antibodies than those with early-stage schizophrenia, providing evidence that the virus may contribute to or support the development of schizophrenia. However, the study only used one testing method to detect the virus and could have benefited from additional varied testing to strengthen its findings.
