Fatigue

Fatigue

Fatigue occurs when materials rupture under repeated or fluctuating loads, even at stress levels far below their static breaking strength. It typically results in brittle failure, even for ductile materials. It is a critical consideration in designing machines and structural components subjected to repetitive or varying loads. The nature of these loadings can range from fluctuating loads like unbalanced pump impellers causing vibrations to repeatedly bending a thin steel rod wire back and forth...

Personality Disorders: Dependent and Obsessive-Compulsive

Personality Disorders: Dependent and Obsessive-Compulsive

Dependent personality disorder and obsessive-compulsive personality disorder are two separate psychological conditions that influence behavior, relationships, and overall life functioning. Though both involve maladaptive behaviors, their core characteristics and motivations differ significantly.
Dependent Personality Disorder
Dependent personality disorder is characterized by an excessive reliance on others to manage various aspects of life. Individuals with this disorder often struggle with...

Self-Discrepancy Theory

Self-Discrepancy Theory

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Anorexia Nervosa

Anorexia Nervosa

Anorexia nervosa is a complex and severe eating disorder characterized by an intense fear of weight gain, an unrelenting pursuit of thinness, and a distorted body image. It often leads to dangerously low body weight relative to an individual's age and height. This disorder is marked by significant physical and psychological consequences, making it one of the most life-threatening psychiatric illnesses.
Symptoms and Physical Effects

Self-Discrepancy and Its Effects

Self-Discrepancy and Its Effects

Self-discrepancy theory explains how people compare their actual self to their ideal and ought selves and how mismatches between these self-guides can lead to emotional distress. Developed by E. Tory Higgins, the theory distinguishes among three components of self-concept: the actual self, the ideal self, and the ought self. These refer respectively to how individuals perceive themselves, how they aspire to be, and how they believe they are obligated to be. Emotional well-being, self-esteem,...

Heart Failure II: Pathophysiology

Heart Failure II: Pathophysiology

Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...

Summary

Patients with functional dysphonia report significantly higher levels of fatigue and perfectionism compared to healthy controls. These findings suggest functional dysphonia may share common pathways with other medically unexplained physical symptoms.

Background:

Functional dysphonia is a voice disorder with no clear organic cause.
Cognitive behavioral therapy (CBT) is used for treatment, with preliminary observations suggesting links to fatigue and perfectionism.

Purpose of the Study:

To investigate and compare levels of general fatigue and perfectionism in individuals with functional dysphonia versus a control group.
To establish if heightened fatigue and perfectionism are characteristic of functional dysphonia.

Main Methods:

A case-control study was conducted in a UK teaching hospital.
Participants included 75 patients with functional dysphonia and 62 age- and sex-matched controls recruited via speech therapy and their friends.
Standardized questionnaires assessed fatigue (Likert and bimodal scoring) and perfectionism traits.

Main Results:

Patients with functional dysphonia exhibited significantly higher mean fatigue scores than controls using both Likert (P = .009) and bimodal (P = .003) scoring systems.
Mean perfectionism scores were also significantly elevated in the functional dysphonia group compared to controls (P = 0.043).

Conclusions:

This study provides the first substantial evidence linking elevated fatigue and perfectionism to functional dysphonia.
These findings suggest functional dysphonia is similar to other medically unexplained physical symptoms, involving somatopsychic distress.
The results have implications for future research and therapeutic approaches for functional dysphonia.
