Subjective Tinnitus and Anxiety Trends Analysis

A 2026 bibliometric analysis has mapped the extensive scientific network linking subjective idiopathic tinnitus and anxiety disorders. The study, published in *Medicine (Baltimore)*, analyzed 262 key publications to identify the most influential researchers, institutions, and central themes driving this field of research.

## How Researchers Mapped the Tinnitus-Anxiety Connection
The research team from Anhui University of Traditional Chinese Medicine used bibliometric methods to create a visual and statistical summary of the field. They started with 773 publications from the Web of Science Core Collection, spanning 2014 to 2025. After screening for relevance, they focused on 262 articles. Using specialized software like VOSviewer and CiteSpace, they analyzed patterns of collaboration between countries and institutions, identified the most cited authors and journals, and tracked the frequency of keywords and references to spot trends. This approach moves beyond reading individual studies to reveal the larger structure of scientific knowledge on tinnitus and anxiety (PMID: 42152361).

## The United States Leads in Research Output and Collaboration
The analysis identified clear leaders in this area of study. The United States produced the highest number of publications, with 58 papers, and maintained the widest network of international collaborations. The most active single institution was the University of Nottingham, contributing 24 publications. When looking at journals, *Frontiers in Neurology* published the most articles on the topic (13), while *LARYNGOSCOPE* was the most cited journal overall, with 314 citations, indicating its published work is frequently used as a foundation by other researchers.

A single researcher stood out for his influence. Gerhard Andersson was both the most prolific author, with 11 publications, and the most cited, with his work accumulating 1,145 citations. This points to a substantial and lasting impact on the direction of the field.

## Prevalence, Severity, and Assessment Tools Are Core Hotspots
Keyword analysis distilled the central concerns of the research. Terms like “tinnitus, anxiety, depression, prevalence, severity, association, hospital anxiety” formed the core clusters. This shows that a significant portion of the literature is dedicated to measuring how common anxiety and depression are among tinnitus patients, and how these emotional states correlate with the reported severity of the tinnitus experience.

The study of co-cited references—papers that are cited together in other articles—provided further clarity. The Tinnitus Handicap Inventory and the Hospital Anxiety and Depression Scale emerged as the most frequently used assessment tools. This confirms that clinical research is heavily focused on quantifying both the disability caused by tinnitus and the accompanying emotional distress. Furthermore, investigations into the underlying mechanisms of tinnitus and potential treatment strategies were highlighted as major areas of attention.

## Implications for Patients and Future Research Directions
This mapping study has practical implications. For clinicians and patients, it reinforces the established, bidirectional link between tinnitus and emotional health. Anxiety can worsen the perception of tinnitus, and the distress of tinnitus can fuel anxiety, creating a difficult cycle. The prominence of assessment scales in the research underscores their importance in clinical practice for evaluating the full impact of the condition.

The findings also guide future scientific efforts. By identifying the most influential authors and collaborative networks, the study points to established hubs of expertise. The hotspot analysis suggests that effective treatment strategies will likely need to address both the auditory and emotional components of the disorder. This aligns with growing interest in therapeutic approaches that target the shared neural mechanisms of tinnitus and emotional dysregulation, such as thalamocortical dysrhythmia. Furthermore, the focus on comorbid anxiety and depression in tinnitus patients shares conceptual ground with research into other sound tolerance disorders, where emotional and empathic processes are also key areas of investigation.

The bibliometric analysis concludes that the field is mature, with established tools and clear focus areas. It provides a roadmap for new researchers to build upon existing knowledge and for the clinical community to integrate this evidence into more holistic patient care.
