Working-age adults' perspectives on living with persistent postural-perceptual dizziness: a qualitative exploratory study.

ABSTRACT: OBJECTIVES:To (a) explore the experiences of persistent postural-perceptual dizziness (PPPD), formerly chronic subjective dizziness on the personal, work and social lives of working-age adults; (b) enhance current understandings of the condition and its impact on the lives of working-age adults and (c) highlight points for consideration and importance to clinical practice. METHODS:This qualitative exploratory study drew on interpretive descriptive methodology. Working-age adults (n=8) diagnosed with PPPD were recruited from a single New Zealand community-based specialist clinic. Data from interviews (n=8) and postinterview reflections (n=2) were analysed using thematic analysis. RESULTS:Three themes were constructed: (1) It sounds like I'm crazy-referring to the lack of medical, social and self-validation associated with PPPD; (2) I'm a shadow of my former self-representing the impact of the condition on sense of self and life trajectory and (3) How will I survive?- highlighting individual coping processes. CONCLUSION:This study contributed to the existing body of knowledge by highlighting the complexity and fluidity of experiencing PPPD. It also drew attention to the tension between the acute illness framework that forms the basis of many therapeutic interactions and the enduring psychosocial support needs of the person experiencing PPPD. The findings highlighted that contextual factors need to be taken into account and that a person-centred and biopsychosocial approach, rather than a condition-specific biomedical approach, is needed for care to be perceived as meaningful and satisfactory.

Project description:BackgroundPersistent postural-perceptual dizziness (PPPD) is a chronic balance disorder, which is characterised by subjective unsteadiness or dizziness that is worse on standing and with visual stimulation. The condition was only recently defined and therefore the prevalence is currently unknown. However, it is likely to include a considerable number of people with chronic balance problems. The symptoms can be debilitating and have a profound impact on quality of life. At present, little is known about the optimal way to treat this condition. A variety of medications may be used, as well as other treatments, such as vestibular rehabilitation. OBJECTIVES: To evaluate the benefits and harms of pharmacological interventions for persistent postural-perceptual dizziness (PPPD). SEARCH METHODS: The Cochrane ENT Information Specialist searched the Cochrane ENT Register; Central Register of Controlled Trials (CENTRAL); Ovid MEDLINE; Ovid Embase; Web of Science; ClinicalTrials.gov; ICTRP and additional sources for published and unpublished trials. The date of the search was 21 November 2022.Selection criteriaWe included randomised controlled trials (RCTs) and quasi-RCTs in adults with PPPD, which compared selective serotonin reuptake inhibitors (SSRIs) or serotonin and norepinephrine reuptake inhibitors (SNRIs) with either placebo or no treatment. We excluded studies that did not use the Bárány Society criteria to diagnose PPPD and studies that followed up participants for less than three months. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methods. Our primary outcomes were: 1) improvement in vestibular symptoms (assessed as a dichotomous outcome - improved or not improved), 2) change in vestibular symptoms (assessed as a continuous outcome, with a score on a numerical scale) and 3) serious adverse events. Our secondary outcomes were: 4) disease-specific health-related quality of life, 5) generic health-related quality of life and 6) other adverse effects. We considered outcomes reported at three time points: 3 to < 6 months, 6 to ≤ 12 months and > 12 months. We planned to use GRADE to assess the certainty of evidence for each outcome. MAIN RESULTS: We identified no studies that met our inclusion criteria.Authors' conclusionsAt present, there is no evidence from placebo-controlled randomised trials regarding pharmacological treatments - specifically SSRIs and SNRIs - for PPPD. Consequently, there is great uncertainty over the use of these treatments for this condition. Further work is needed to establish whether any treatments are effective at improving the symptoms of PPPD, and whether their use is associated with any adverse effects.

We considered outcomes reported at three time points: 3 to < 6 months, 6 to ≤ 12 months and > 12 months. We planned to use GRADE to assess the certainty of evidence for each outcome. MAIN RESULTS: Few randomised controlled trials have been conducted to assess the efficacy of different treatments for PPPD compared to no treatment (or placebo). Of the few studies we identified, only one followed up participants for at least three months, therefore most were not eligible for inclusion in this review. We identified one study from South Korea that compared the use of transcranial direct current stimulation to a sham procedure in 24 people with PPPD. This is a technique that involves electrical stimulation of the brain with a weak current, through electrodes that are placed onto the scalp. This study provided some information on the occurrence of adverse effects, and also on disease-specific quality of life at three months of follow-up. The other outcomes of interest in this review were not assessed. As this is a single, small study we cannot draw any meaningful conclusions from the numeric results. AUTHORS' CONCLUSIONS: Further work is necessary to determine whether any non-pharmacological interventions may be effective for the treatment of PPPD and to assess whether they are associated with any potential harms. As this is a chronic disease, future trials should follow up participants for a sufficient period of time to assess whether there is a persisting impact on the severity of the disease, rather than only observing short-term effects.

Project description:IntroductionPersistent postural-perceptual dizziness (PPPD) (ICD-11) and anxiety disorders (ANX) share behavioural symptoms like anxiety, avoidance, social withdrawal, hyperarousal, or palpitation as well as neurological symptoms like vertigo, stance and gait disorders. Furthermore, previous studies have shown a bidirectional link between vestibulo-spatial and anxiety neural networks. So far, there have been no neuroimaging-studies comparing these groups.ObjectivesThe aim of this explorative study was to investigate differences and similarities of neural correlates between these two patient groups and to compare their findings with a healthy control group.Methods63 participants, divided in two patient groups (ANX = 20 and PPPD = 14) and two sex and age matched healthy control groups (HC-A = 16, HC-P = 13) were included. Anxiety and dizziness related pictures were shown during fMRI-measurements in a block-design in order to induce emotional responses. All subjects filled in questionnaires regarding vertigo (VSS, VHQ), anxiety (STAI), depression (BDI-II), alexithymia (TAS), and illness-perception (IPQ). After modelling the BOLD response with a standard canonical HRF, voxel-wise t-tests between conditions (emotional-negative vs neutral stimuli) were used to generate statistical contrast maps and identify relevant brain areas (pFDR < 0.05, cluster size >30 voxels). ROI-analyses were performed for amygdala, cingulate gyrus, hippocampus, inferior frontal gyrus, insula, supramarginal gyrus and thalamus (p ≤ 0.05).ResultsPatient groups differed from both HC groups regarding anxiety, dizziness, depression and alexithymia scores; ratings of the PPPD group and the ANX group did differ significantly only in the VSS subscale 'vertigo and related symptoms' (VSS-VER). The PPPD group showed increased neural responses in the vestibulo-spatial network, especially in the supramarginal gyrus (SMG), and superior temporal gyrus (STG), compared to ANX and HC-P group. The PPPD group showed increased neural responses compared to the HC-P group in the anxiety network including amygdala, insula, lentiform gyrus, hippocampus, inferior frontal gyrus (IFG) and brainstem. Neuronal responses were enhanced in visual structures, e.g. fusiform gyrus, middle occipital gyrus, and in the medial orbitofrontal cortex (mOFC) in healthy controls compared to patients with ANX and PPPD, and in the ANX group compared to the PPPD group.ConclusionsThese findings indicate that neuronal responses to emotional information in the PPPD and the ANX group are comparable in anxiety networks but not in vestibulo-spatial networks. Patients with PPPD revealed a stronger neuronal response especially in SMG and STG compared to the ANX and the HC group. These results might suggest higher sensitivity and poorer adaptation processes in the PPPD group to anxiety and dizziness related pictures. Stronger activation in visual processing areas in HC subjects might be due to less emotional and more visual processing strategies.

Project description:ObjectiveTo investigate whether additional Cognitive Behavior Therapy (CBT) combined with conventional therapy improves outcomes for patients with Persistent Postural-Perceptual Dizziness (PPPD) compared with conventional therapy alone.MethodsTwo reviewers independently searched PubMed, Embase, Web of Science, Cochrane Library, and ClinicalTrials.gov for relevant Randomized Controlled Trials (RCTs) examining CBT for PPPD which were conducted and published in English from January 2002 to November 2022. RCTs reporting any indicators for assessing corresponding symptoms of PPPD were included, such as Dizziness Handicap Inventory (DHI), Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD), Hospital Anxiety and Depression Scale (HADS), and Patient Health Questionnaire-9 (PHQ-9). Two independent reviewers conducted extraction of relevant information and evaluation of risk of bias. The Cochrane Collaboration risk of bias tool version 1.0 was used to evaluate risks and assess the quality of the included studies, and Cochrane Review Manager 5.3 software (RevMan 5.3) was used to perform meta-analyses.ResultsThe results of six RCTs indicated that combining additional CBT with conventional therapy significantly improved outcomes for PPPD patients compared with conventional therapy alone, especially in DHI-Total scores (Mean Difference [MD = -8.17], 95% Confidence Interval [95% CI: -10.26, -6.09], p < 0.00001), HAMA scores (MD = -2.76, 95% CI: [-3.57, -1.94], p < 0.00001), GAD-7 scores (MD = -2.50, 95% CI [-3.29, -1.70], p < 0.00001), and PHQ-9 scores (MD = -2.29, 95% CI [-3.04, -1.55], p < 0.00001). Subgroup analysis revealed a significant benefit of additional CBT compared with conventional therapies alone, including Vestibular Rehabilitation Therapy (VRT) (MD = -8.70, 95% CI: [-12.17, -5.22], p < 0.00001), Selective Serotonin Reuptake Inhibitor (SSRI) (with controlled SSRI: MD = -10.70, 95% CI: [-14.97, -6.43], p < 0.00001), and VRT combined with SSRI (MD = -6.08, 95% CI [-9.49, -2.67], p = 0.0005) in DHI-Total scores.ConclusionAdditional CBT combined with conventional therapy may provide additional improvement for patients with PPPD compared with conventional therapy alone. However, more RCTs are needed to support and guide the application of CBT in treating PPPD.Level of evidenceI; Systematic review of RCTs.
