This is most likely to happen in new situations or when they meet new people. However, there is some debate as to whether anxiety causes hypervigilance, or whether anxiety disorders result from hypervigilant behavior. A study , conducted on rats, found that a hypervigilant state made them more vulnerable to anxiety.

More research is needed to understand whether hypervigilance is a symptom or a cause of anxiety disorders. There are common triggers that can bring on hypervigilant behavior in those who are affected by it.

These triggers include:. The first step in treatment if a person experiences hypervigilance due to domestic violence or military combat, is to remove them from the dangerous environment.

When someone experiences hypervigilance due to a mental health condition, other treatments that may help include:. As well as taking medication if it is prescribed and attending therapy if they have been referred, people may look for other ways to manage hypervigilance.

Legg, PhD, PsyD — By Lana Burgess on September 7, What is it? It can also be difficult for those who experience frequent hypervigilance, like those with PTSD, to sleep well. If you experience recurring hypervigilance, you may start to develop behaviors to calm your anxiety or counteract perceived threats.

If you fear assault or danger, for example, you may start carrying a concealed weapon. If you have severe social anxiety , you may rely on day dreaming or non-participation in events.

These symptoms can result in social isolation and damaged relationships. Anxiety is one of the most common causes of hypervigilance. PTSD is another common a cause of hypervigilance. PTSD can cause you to be tense. You may constantly scan the area for perceived threats. Schizophrenia can also cause hypervigilance.

Hypervigilance can worsen other symptoms of the condition, such as paranoia or hallucinations. There are some common triggers that can cause or contribute to episodes of hypervigilance. These include:. To treat hypervigilance, your doctor will determine the underlying cause of the condition.

Cognitive behavioral therapy CBT : CBT is often effective at helping to treat anxiety. Your therapist will guide these conversations. Your therapist can help you identify what causes your hypervigilance and how to deal with it. Exposure therapy: Exposure therapy can be helpful if you have PTSD.

Exposure therapy allows you to safely face fears and memories of trauma slowly so that you can learn how to manage the flashbacks and anxiety. Eye movement desensitization and reprocessing EMDR : EMDR combines exposure therapy with guided eye movements.

This can ultimately change how you react to traumatic memories. Read our review of the best online therapy options to find the right fit for you. Severe cases of anxiety and PTSD may require more intensive treatment, including prescription medications. Medications can include:.

Here are some strategies that can help:. Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available. Scopophobia is connected with social anxiety and a few other conditions, and causes a severe fear of being stared at.

Zoophobia is the fear of animals. It can refer to a fear of a specific animal or to a fear of all animals. Fear of sex, or genophobia, is a phobia with many potential causes ranging from physical conditions vaginismus or erectile dysfunction to traumatic….

The screen covered a visual angle of 90 degrees horizontally and 59 degrees vertically. Any eye movement deviating from the primary eye position was identified in real-time so as to minimize the risk of secondary ocular torsion caused by oblique eye movements.

The tOKN frequency and gain were recorded using at Hz head-mounted Chronos Eye Tracker CET; Chronos Inc. The data was retrieved and analyzed according to well-established and previously published procedures.

The optokinetic stimulation consisted of a high-resolution image of 26 black lines, 1. Visual angle of the lines was Each trial started with the stimulus being presented at rest for 10 seconds, followed by 20 seconds of optokinetic stimulation, before ending with 5 seconds of static presentation.

This allowed the visual scene to rotate four full circles, starting and ending in the same position and orientation.

The optokinetic stimulation is represented in Supplementary Figure S1. The protocol included three different levels of attentional engagement depending on the visual stimulation: focused, neutral, and divided. In the condition with focused attentional engagement on the visual stimulation, participants were instructed to verbally report each rotation of the optokinetic stimulation while maintaining gaze fixation on the fixation point; this was performed simultaneously with the stimulation.

The number of correct rotations reported represented the attentional engagement score, with four points accounting for a perfect performance. In the condition with the neutral level of attentional engagement on the visual stimulation, participants were tasked with simply viewing the visual stimulation while maintaining their gaze on the central fixation point.

No task was given and subjects were instructed to relax and simply sit through the protocol. The condition with divided attentional engagement on the visual stimulation featured a distracting task being presented to the participants simultaneously to the visual stimulation.

To ensure a shift of the attentional focus away from visual to auditory cues, the Paced Auditory Serial Addition Test PASAT with a 2-second interval between stimuli 33 was submitted to the participants. The PASAT consists of a sequence of digits presented through a speaker, with each digit separated by a fixed interval.

The subjects were asked to add consecutive digits in response to the numbers called out and immediately report the sum verbally. The PASAT started 5 seconds before the active optokinetic rotation and ended 5 seconds after it had stopped.

Attentional tasks were compared using repeated measures ANOVA with α of 0. Mauchly's sphericity test was implemented for each variable. Post hoc analyses of the ANOVA results were performed with Holm corrections for comparing families of three.

Statistical analyses were performed using JASP version 0. A repeated measures ANOVA was performed on the pupil size data. Post hoc comparisons with Holm corrections were used to compare pupil sizes between focused and divided attentional tasks to those during neutral viewing.

In addition, correlation analyses were performed to assess the relationship between pupil size and the torsional nystagmus parameters. In addition, the OKR is known to adapt over time. Pupillometry revealed that pupil sizes during both the focused Correlation analyses revealed no significant relationship between pupil size, torsional velocities, or number of nystagmus beats.

This analysis was performed both within each viewing condition, as well as on pooled data. There was consequently no evidence indicating that the nystagmus response was influenced by alertness.

Attentional Influences on the Optokinetic Reflex. Representative traces of the OKR for all attentional levels are illustrated in Figure 1. Attention had no significant effect on the peak slow-phase amplitude, although sphericity could not be assumed for this variable. Quick-phase amplitudes were similarly unaffected.

These findings reflect that both focused and divided attentional focus upregulates the OKR velocity without altering the amplitude. This means that the increased OKN gain was likely due to increased levels of alertness. Figure 1.

These results illustrate how increased visual attention upregulates the optokinetic nystagmus. Starting amplitudes have been adjusted to allow for simultaneous presentation of all traces, and blinks have been replaced by bridging lines across data points.

B An interval plot outlining the mean and SD of the number of nystagmus beats for each attentional level, showing increased responses during both focused and divided attentional tasks compared to neutral viewing. The number of nystagmus beats, reflecting the activity of the velocity storage, was greatly influenced by the level of attentional focus.

Altogether, this indicates that greater attentional focus is associated with increased activity in the velocity storage mechanism.

This means that the more attention the subject paid to the visual stimulus, the greater its influence on the viewer's neural integration of motion. Temporal Distribution of the Optokinetic Responses. In order to assess if attention levels had any significant effect on OKN adaptation over time, a Pearson's correlation was performed between the starting time of each slow-phase and its corresponding velocity across all subjects.

No significant correlation could be found for any attentional level. However, the general distribution of the slow phases was noticeably affected by attentional focus Fig. To further investigate how the attentional level influences the OKN over time, the number of OKN beats were calculated for each quarter of the stimulation period.

To illustrate this relationship, each quarter was plotted as a percentage of the total number of OKN beats for each attentional level Fig. These results indicate that OKN adaptation over time differs based on the viewer's attention to visual motion.

Figure 3. The distribution of slow-phase velocities over time. A The Kernel density plots signify distribution density of OKN slow-phases across the stimulation period, with darker regions corresponding to increased number of data points for the eye movement velocity at that point in time.

B The interval plots represent the proportion of OKN beats for each quarter Q1—Q4 throughout the stimulation period for each attentional level, presented on a scale of 0 to 1, also showing the standard deviation. The focused task caused a steady decline in relative OKN distribution, whereas the neutral task evens out after an initial cluster of beats.

The divided task yielded clusters in the first and third quarter, though with a decreasing trend toward the fourth quarter. A similar trend can be seen for the neutral condition.

Individual Considerations in the Attentional Tasks. As both focused and divided attentional tasks rely on individual strategies, each subject was asked about their method of approaching both tasks. This was carried out after all measurements had been collected, so as to not influence the subject.

The divided attentional task, featuring the PASAT, was not associated with any specific strategy in general, with all subjects being naïve to the procedure apart from the brief introduction outlined in the methods section. To assess any relationship between success rates in the divided attentional task and the OKN, Pearson's correlation coefficients were retrieved between the PASAT scores and eye movement parameters, revealing no significant correlation.

All subjects reported the same strategy for resolving the focused attention task. This was done by maintaining focus on the line closest to the gaze-fixation point, keeping a mental note of when it passed by its estimated starting position.

All subject achieved a perfect score for estimating the number of rotations. For this reason, no further statistical evaluation was warranted. This study outlines the effects of visual attention on the optokinetic response, showing how the velocity storage mechanism is deeply linked to the level of attention an individual commits to a moving visual scene.

As reflected by the number of nystagmus beats, the divided visual attention is associated with decreased motion processing, whereas an increase is seen for tasks demanding focused visual focus.

The fact that OKN gain and distribution density was increased to both divided and focused attentional levels, both requiring high alertness, highlights the complexity of visual sensorimotor integration.

The study design consequently allowed us to control for alertness. The fact that no relationship was found between pupil size and nystagmus responses is in contrast to previous findings having shown that pupil size was moderately correlated to torsional slow-phase velocities.

Ultimately, these results indicate that pupil sizes could not explain the changes in nystagmus parameters. Differences in the eye movement response between focused and divided attentional tasks may therefore be attributed the attentional level, as seen in the analysis of OKN frequency.

Similarities between the two tasks may instead be due to the level of alertness, here illustrated in the OKN gain.

In order to contextualize these results, it is important to identify that optokinetic nystagmus is a gaze-stabilizing eye movement which reflects a need to maintain visual integrity during motion. The two primary mechanisms underlying gaze stability are the vestibulo-ocular reflex VOR and the OKR, which are thought to have evolved in parallel.

The fact that focused visual attention correlates with greater VSM activity fits well within the framework of patients suffering from non-vestibular vertigo due to increased visual motion sensitivity.

This finding further supports the claim that visual attention, more so than alertness, influences the VSM. In light of this, the OKN may prove a valuable proxy for assessing visual attention, and allow personalized rehabilitation through following the recorded data over time.

However, as previously addressed, attention and alertness are separate neural entities, although conceptually related. These results indicate that alertness may have influenced the tOKN gain.

The PASAT protocol inducing divided visual attention necessitates a broad activation of cortical structures, including the left prefrontal cortex and left parietal lobe and visual associative areas.

The methodological approach in this study did produce some limitations in how the data may be interpreted. Through continuously providing PASAT answers, the subjects were confirmed to be engaged with the task, although it is difficult to assess the exact level of attention within individual subjects.

PASAT proficiency does not depend on a certain level of neural activation, and so it is not surprising that no correlation could be seen between the number of correct answers given and the OKN. In addition to the number and gain of the OKR, this study investigated the effects on peak amplitudes, both for slow and quick phases.

The main aim of calculating peak amplitudes was to assess whether the attentional level would affect the integration of stimulation amplitudes into the OKR i. if increased attentional levels would correspond to the movement being treated as covering a greater distance.

There was, however, no significant effect on this outcome based on the attentional task. Peak slow-phase amplitudes also produced a high degree of variance. It should be noted that the OKN gain was calculated from each slow phase for every trial, whereas the peak amplitudes were retrieved twice per trial, one positive and one negative.

This meant that the number of traces available for statistical analysis were much lower for peak amplitudes. The comparative lack of power naturally limits the contextualization of how OKN peak amplitudes are affected by the attentional tasks.

In conclusion, this study is the first in implementing a range of perceptual tasks to show that visual attention and general alertness influences separate aspects of the optokinetic reflex. The number of OKN beats was highest during focused levels of visual attention and lowest during the divided attention task, reflecting greater involvement of the velocity storage mechanism in integrating visual motion.

In addition, OKN gain increased during both divided and focused attention levels. This was also true for the pupil size, which may reflect that the increased gain was due to a heightened alertness.

Hypervigilance can lead to a variety of obsessive behavior patterns, as well as producing difficulties with social interaction and relationships.

Hypervigilance is differentiated from dysphoric hyperarousal in that the person remains cogent and aware of their surroundings. In dysphoric hyperarousal, a person with PTSD may lose contact with reality and re-experience the traumatic event verbatim. Where there have been multiple traumas, a person may become hypervigilant and suffer severe anxiety attacks intense enough to induce a delusional state where the effects of related traumas overlap.

This can result in the thousand-yard stare. Hypervigilance can be a symptom of post-traumatic stress disorder [4] PTSD and various types of anxiety disorders.

It is distinguished from paranoia. Paranoid diagnoses, such as those that can occur in schizophrenia , can seem superficially similar, but are characteristically different. People suffering from hypervigilance may become preoccupied with scanning their environment for possible threats.

They might overreact to loud and unexpected noises, exhibit an overactive startle response or become agitated in highly crowded or noisy environments. They will often have a difficult time getting to sleep or staying asleep. After resolution of the situation demanding their attention, people exhibiting hypervigilance may be exhausted and require time before returning to normal activities.
