Explaining Terms:

Culture-Bound

• A culture-bound syndrome is often defined as a combination of psychiatric and somatic symptoms that are considered to be a recognizable disease only within a specific society or culture. There are no objective biochemical or structural alterations of body organs or functions, and the disease is not recognized in other cultures.

The term "culture-bound" is nowadays often challenged when conditions spread beyond their original cultural context, often influenced by global media and communication, thereby becoming more of a socially constructed condition. In other words, they can be recognized cross-culturally due to globalization.

• Potential mechanism behind the development and spread of culture-bound syndromes:

a — Sensitization: Individuals can become sensitized to certain conditions or symptoms based on their pre-existing categories, narratives, or guesses. This sensitivity can affect how they perceive and interpret bodily sensations or experiences. For example, being sensitized to the idea of feeling crawling ants can lead to heightened awareness and false positives of such sensations. Sensitization can influence the threshold for interpreting ambiguous stimuli and contribute to the development of conditions like chronic pain or panic disorder.

b — Reinterpretation of ambiguous stimuli: Similar to sensitization, this interpretation focuses on the role of categorization and narrative frameworks in shaping perception. It suggests that the application of different categories or frameworks can lead to varied interpretations of ambiguous stimuli. By changing the lens through which one views a situation or experience, different aspects may become more salient or recognizable. This process is exemplified in the visual illusions where the recognition of an image becomes clearer once the correct framework is applied.

c — Signaling spirals: This interpretation considers the social signaling aspect of certain conditions. It proposes that individuals may adopt or amplify symptoms or behaviors to signal their alignment with cultural norms or to establish themselves as "better than average" in terms of empathy or morality. The belief systems and cultural expectations surrounding an event or condition can influence the extent to which individuals engage in signaling behaviors. For instance, if a cultural belief suggests that mourning for an extended period is expected after the death of a loved one, individuals may conform to this expectation to signal their conformity or perceived virtue.

Sociogenic

This term refers specifically to illnesses or conditions that arise predominantly from social interactions and expectations, and can transcend cultural boundaries.

Sociogenic illnesses are health conditions that manifest in groups of people, not because of direct, physical agents like biological pathogens (viruses, bacteria) or clearly identifiable environmental causes (chemicals, toxins). Instead, these illnesses arise from complex, indirect factors such as social dynamics or broader aspects of the environment that affect mental and physical well-being such as social isolation or high-stress environments.

Sociogenic illnesses often involve physical symptoms and are understood within a medical or psychological framework.

How can we know which medical treatments and claims are trustworthy, if we can't read the evidence?

The menstrual distress questionnaire (MEDI-Q) is a tool developed for assessing menstruation-related distress. It includes 25 items that cover areas such as pain, discomfort, psychic or cognitive changes, gastrointestinal symptoms, and changes in physiological functions.
The MEDI-Q is a valuable tool in academic and clinical research to study the impact of menstrual symptoms on women's lives. It helps in quantifying the severity and range of symptoms.
It is also utilized in public health research to understand the prevalence and impact of menstrual distress in the population, contributing to better public health policies and educational programs.
And yet...it is not publicly available, which raises significant concerns:
