Summary
Visual height intolerance (vHI) affects nearly a third of adults, often starting in adolescence. Acrophobia, fear of heights, impacts over 6% and is linked to anxiety and depression.
Area of Science:
- Psychology
- Epidemiology
- Clinical Neuroscience
Background:
- Visual height intolerance (vHI) and acrophobia are common phobias.
- Understanding their prevalence and clinical characteristics is crucial for public health.
Purpose of the Study:
- Estimate lifetime and point prevalence of vHI and acrophobia in the general population.
- Define clinical features and comorbidities of vHI and acrophobia.
- Investigate the relationship between migraine, vHI, and acrophobia.
Main Methods:
- A population-based cross-sectional telephone survey of 2,012 German individuals aged 14+.
- Case-control study design assessing neurological conditions, symptom patterns, and comorbidities (DSM-IV-TR).
Main Results:
- Lifetime prevalence of vHI was 28.5% (32.4% women, 24.5% men), with onset often in the second decade.
- Lifetime prevalence of acrophobia was 6.4% (8.6% women, 4.1% men); point prevalence was 2.0%.
- VHI and acrophobia showed high rates of comorbid anxiety and depressive disorders; migraine predicted and resulted from acrophobia.
Conclusions:
- VHI is highly prevalent, with a significant portion experiencing panic attacks or developing acrophobia.
- VHI and acrophobia are associated with substantial psychological distress and comorbidities.
- Migraine appears to have a bidirectional relationship with acrophobia.

6.1K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

8.3K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

2.0K
Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round...

01:09Preparedness and Phobias
472
Human fear responses to certain stimuli, such as darkness, heights, deep water, and blood, can often arise despite the absence of direct negative experiences. This phenomenon is rooted in evolutionary psychology, which posits that humans have developed a predisposition to fear stimuli that historically posed significant survival threats. This predisposition, known as preparedness, suggests that early humans who developed a fear of potentially dangerous entities, such as venomous snakes and...

1.7K
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

1.2K
Anxiety is a common mental disorder featuring excessive worry, fear, and apprehension, significantly affecting daily life. People with anxiety disorders experience persistent and intense anxiety, interrupting their everyday functioning.
Individuals with anxiety often experience a range of physical and emotional symptoms, including sweating, trembling, tachycardia, and disturbances in sleep patterns. These symptoms vary in intensity and frequency but are generally disruptive and distressing.
