Perspectives of adults with neurofibromatosis regarding the design of psychosocial trials: Results from an anonymous online survey.

BACKGROUND/AIMS: Individuals with neurofibromatosis, including neurofibromatosis 1 (NF1), neurofibromatosis 2 (NF2)-related schwannomatosis (SWN), and other forms of SWN, often experience disease manifestations and mental health difficulties for which psychosocial interventions may help. An anonymous online survey of adults with neurofibromatosis assessed their physical, social, and emotional well-being and preferences about psychosocial interventions to inform clinical trial design. METHODS: Neurofibromatosis clinical researchers and patient representatives from the Response Evaluation in Neurofibromatosis and Schwannomatosis International Collaboration developed the survey. Eligibility criteria included age ≥ 18 years, self-reported diagnosis of NF1, NF2, or SWN, and ability to read and understand English. The online survey was distributed internationally by the Neurofibromatosis Registry and other neurofibromatosis foundations from June to August 2020. RESULTS: Surveys were completed by 630 adults (18-81 years of age; M = 45.5) with NF1 (78%), NF2 (14%), and SWN (8%) who were mostly White, not Hispanic/Latino, female, and from the United States. The majority (91%) reported that their neurofibromatosis symptoms had at least some impact on daily life. In the total sample, 51% endorsed a mental health diagnosis, and 27% without a diagnosis believed they had an undiagnosed mental health condition. Participants indicated that neurofibromatosis affected their emotional (44%), physical (38%), and social (35%) functioning to a high degree. Few reported ever having participated in a drug (6%) or psychosocial (7%) clinical trial, yet 68% reported they "probably" or "definitely" would want to participate in a psychosocial trial if it targeted a relevant concern. Top treatment targets were anxiety, healthier lifestyle, and daily stress. Top barriers to participating in psychosocial trials were distance to clinic, costs, and time commitment. Respondents preferred interventions delivered by clinicians via individual sessions or a combination of group and individual sessions, with limited in-person and mostly remote participation. There were no significant group differences by neurofibromatosis type in willingness to participate in psychosocial trials (p = 0.27). Regarding interest in intervention targets, adults with SWN were more likely to prefer psychosocial trials for pain support compared to those with NF1 (p < 0.001) and NF2 (p < 0.001). CONCLUSION: This study conducted the largest survey assessing physical symptoms, mental health needs, and preferences for psychosocial trials in adults with neurofibromatosis. Results indicate a high prevalence of disease manifestations, psychosocial difficulties, and untreated mental health problems in adults with neurofibromatosis and a high degree of willingness to participate in psychosocial clinical trials. Patient preferences should be considered when designing and implementing psychosocial interventions to develop the most feasible and meaningful studies.

Health literacy assessment in adults with neurofibromatosis: electronic and short-form measurement using FCCHL and Health LiTT.

Determining health literacy level is an important prerequisite for effective patient education. We assessed multiple dimensions of health literacy and sociodemographic predictors of health literacy in patients with neurofibromatosis. In 86 individuals with a confirmed diagnosis of neurofibromatosis 1 (NF1), neurofibromatosis 2 (NF2), or schwannomatosis, we assessed health literacy status using two HL tools-the adapted functional, communicative, and critical health literacy scale (adapted FCCHL) and health literacy assessment using talking touchscreen technology (Health LiTT). Factor analyses of the adapted FCCHL in NF patients showed factor structure and psychometric properties similar to pilot work in other patient populations. As a group, patients with NF had moderate scores on the Health LiTT and moderate to high scores on the adapted FCCHL, with the highest score on the functional health literacy subscale. Patients with NF1, those with lower education and those with learning disabilities had lower scores on Health LiTT; in multivariate analysis, learning disability and education remained significant predictors of HealthLiTT scores. Only lower education was associated with lower adapted FCCHL scores. Results suggest utilizing health literacy tools in NF patients is feasible and could provide physicians with valuable information to tailor health communication to subpopulations with lower health literacy levels.

Systematic Review and Meta-analysis of Executive Functions in Preschool and School-Age Children With Neurofibromatosis Type 1.

OBJECTIVES: Neurofibromatosis type 1 (NF1) is a genetic disorder in which the most frequent complication in children is learning disabilities. Over the past decade, growing arguments support the idea that executive dysfunction is a core deficit in children with NF1. However, some data remain inconsistent. The aim of this study was to determine the magnitude of impairment for each executive function (EF) and clarify the impact of methodological choices and participant's characteristics on EFs. METHODS: In this meta-analysis, 19 studies met the selection criteria and were included with data from a total of 805 children with NF1 and 667 controls. Based on the Diamond's model (2013), EF measures were coded separately according to the following EF components: working memory, inhibitory control, cognitive flexibility, planning/problem solving. The review protocol was registered with PROSPERO (International prospective register of systematic reviews; CRD42017068808). RESULTS: A significant executive dysfunction in children with NF1 is demonstrated. Subgroup analysis showed that the impairment varied as a function of the specific component of executive functioning. The effect size for working memory and planning/problem solving was moderate whereas it was small for inhibitory control and cognitive flexibility. Executive dysfunction seems to be greater with increasing age whereas assessment tool type, intellectual performance, attention deficit hyperactivity disorder and control group composition did not seem to affect EF results. CONCLUSIONS: EF deficits are a core feature in children with NF1 and an early identification of executive dysfunctions is essential to limit their impact on the quality of life.

First use of patient reported outcomes measurement information system (PROMIS) measures in adults with neurofibromatosis.

The patient reported outcomes measurement information system (PROMIS) provides clinicians and researchers access to reliable, validated measures of physical, mental, and social well-being. The use of PROMIS can facilitate comparisons among clinical subpopulations and with the U.S. general population. We report on the first study using PROMIS measures in patients with neurofibromatosis (NF). Eighty-six adult patients (mean age = 44; 55% female; 87% white; 50% NF1, 41% NF2 and 9% schwannomatosis) completed a battery of PROMIS computerized adaptive tests (CATs). Across all PROMIS instruments, mean scores for each CAT were between 48.97 and 52.60, which is within ±0.5 SD of the U.S. general population norms. However, scores were distributed across a broad range for each PROMIS measure (±3 SDs). Clinically meaningful scores (defined >1 SD impairment) were observed in 20% (pain interference), 17% (pain behavior), 16% (physical function), 16% (anxiety), 16% (depression), 15% (satisfaction with social roles), 13% (fatigue), 6% (anger), and 5% (satisfaction with discretionary social activities) of the sample. All PROMIS measures were highly interrelated in bivariate analysis (P ≤ .001). There were no differences in PROMIS scores by disease type (NF1, NF2 and schwannomatosis), or self reported learning disabilities, or compared with the US population. Scores suggest a broad continuum of symptoms and functioning in patients with NF that is not affected by NF type, as well as interrelation among the physical and psychosocial domains as measured by PROMIS. PROMIS measures may be useful in clinical practice to monitor changes in symptoms and functioning over time, as well as in clinical trials to determine patient reported changes during drug and psychosocial clinical trials.

Relationship between whole-body tumor burden, clinical phenotype, and quality of life in patients with neurofibromatosis.

Patients with neurofibromatosis 1 (NF1), NF2, and schwannomatosis share a predisposition to develop multiple nerve sheath tumors. Previous studies have demonstrated that patients with NF1 and NF2 have reduced quality of life (QOL), but no studies have examined the relationship between whole-body tumor burden and QOL in these patients. We administered a QOL questionnaire (the SF-36) and a visual analog pain scale (VAS) to a previously described cohort of adult neurofibromatosis patients undergoing whole-body MRI. One-sample t-tests were used to compare norm-based SF-36 scores to weighted population means. Spearman correlation coefficients and multiple linear regression analyses controlling for demographic and disease-specific clinical variable were used to relate whole-body tumor volume to QOL scales. Two hundred forty-five patients (142 NF1, 53 NF2, 50 schwannomatosis) completed the study. Subjects showed deficits in selected subscales of the SF-36 compared to adjusted general population means. In bivariate analysis, increased tumor volume was significantly associated with pain in schwannomatosis patients, as measured by the SF-36 bodily pain subscale (rho = -0.287, P = 0.04) and VAS (rho = 0.34, P = 0.02). Regression models for NF2 patients showed a positive relationship between tumor burden and increased pain, as measured by the SF-36 (P = 0.008). Patients with NF1, NF2, and schwannomatosis suffer from reduced QOL, although only pain shows a clear relationship to patient's overall tumor burden. These findings suggest that internal tumor volume is not a primary contributor to QOL and emphasize the need for comprehensive treatment approaches that go beyond tumor-focused therapies such as surgery by including psychosocial interventions.

Appearance concerns among women with neurofibromatosis: examining sexual/bodily and social self-consciousness.

OBJECTIVE: Neurofibromatosis (NF) 1 and 2 have distinct appearance effects, yet little research has examined patients' appearance concerns. We assessed appearance concerns and self-consciousness, self-esteem, and loneliness among women with NF. METHODS: Women with NF1 (n = 79) and NF2 (n = 48) completed the Derriford Appearance Scale to assess appearance concerns and sexual/bodily and social self-consciousness, Rosenberg Self-Esteem Scale, and UCLA Loneliness Scale. Women's appearance concerns were coded to determine whether they were NF-related and whether psychosocial factors contributed to the concerns. RESULTS: A total of 85% of women reported appearance concerns, many of which were NF-related and attributed to psychosocial factors. Women with NF1 reported significantly more sexual/bodily self-consciousness but similar levels of social self-consciousness compared with women with NF2. Significantly higher sexual/bodily self-consciousness was found among married/cohabiting women regardless of NF group. Compared with general population norms and breast cancer survivors (BCS), women with NF1 reported significantly greater sexual/bodily and social self-consciousness. Women with NF2 reported less sexual/bodily self-consciousness compared with population norms, yet tended to report greater sexual/bodily self-consciousness than BCS. Women with NF2 reported significantly greater social self-consciousness compared with population norms and BCS. For both NF1 and NF2, higher levels of sexual/bodily and social self-consciousness were related to lower self-esteem and higher levels of social self-consciousness to more loneliness. CONCLUSIONS: Appearance concerns are prevalent, and social self-consciousness is high, among women with NF1 and NF2. Women with NF1 compared with NF2 experience more sexual/bodily self-consciousness. Providers should assess the impact of NF on women's self-perceptions and address sexual, body image, and social concerns.

Emotional functioning of patients with neurofibromatosis tumor suppressor syndrome.

PURPOSE: Although patients with neurofibromatosis are predisposed to multiple nerve sheath tumors that can develop anywhere in the body and cause significant morbidity (e.g., hearing loss; pain), little research has examined emotional correlates of neurofibromatosis. The purpose of this study was to examine emotional functioning among adult patients with neurofibromatosis. METHODS: A total of 248 patients with neurofibromatosis (neurofibromatosis 1, neurofibromatosis 2, or schwannomatosis) who received care at a specialized clinic completed validated measures to assess symptoms of depression and anxiety, level of perceived stress, and self-esteem. RESULTS: Patients with neurofibromatosis reported significantly more symptoms of depression and anxiety, higher levels of perceived stress, and lower levels of self-esteem as compared with general population norms. No significant differences were found among patients with neurofibromatosis 1, neurofibromatosis 2, and schwannomatosis, and emotional functioning was not significantly associated with disease severity. However, increased symptoms of depression and anxiety, higher levels of perceived stress, and lower levels of self-esteem were associated with a higher frequency of self-reported medical visits in the past year (P values ≤0.05). CONCLUSION: Neurofibromatosis appears to be associated with reduced emotional functioning. Although further research is needed, these findings suggest a role for a multidisciplinary treatment approach to address emotional distress among adult patients with neurofibromatosis.

A qualitative study of the impact of living with neurofibromatosis type 2.

Neurofibromatosis type 2 (Nf2) is an inherited autosomal dominant syndrome characterised by the development of nervous system tumours, ocular abnormalities and skin tumours. Symptoms of Nf2 can vary depending on the size and location of the tumour and include hearing loss, balance deficits and facial palsy. This study explored the physical, emotional and social impact of Nf2. Six patients were recruited through a neurofibromatosis clinic and underwent a semi-structured interview. Interviews were recorded and analysed using Framework analysis. Participants spoke of the negative impact of Nf2 on daily activities, including work. Social isolation resulted from the avoidance of social situations and was often a consequence of difficulties with communication due to loss of hearing. Patients expressed a range of negative emotional reactions in response to their diagnosis and the impact of the disease. Furthermore, the findings highlighted the important role of partners and family who were relied on for physical as well as emotional and psychological support. Patients also expressed frustration at the limited awareness of Nf2 among health professionals and a desire for improved access to information on Nf2 within their local community.

Effects of a mind-body program on symptoms of depression and perceived stress among adults with neurofibromatosis type 2 who are deaf: A live-video randomized controlled trial.

INTRODUCTION: Neurofibromatosis type 2 (NF2) is a rare, progressive and incurable genetic disorder associated with progressive hearing loss and eventual deafness. As a group, patients with NF report high levels of stress and depressive symptoms. However, no studies have explored improvement in these symptoms after psychosocial interventions. We have previously shown that a mind-body program tailored to adults with NF2 who are deaf (the Relaxation Response and Resiliency Program for Deaf NF2, d3RP-NF2) improves quality of life and resiliency over and above a Health Enhancement program when both are delivered via live-video and assisted by Communication Access Realtime Translation (CART). Here we tested the effects of the programs on depression and perceived stress. METHODS: Forty-five patients with NF2 and significant hearing loss were randomized to the d3RP-NF2 or Health-Enhancement program and completed measures of depression (PHQ-9) and perceived stress (PSS-10) at baseline, post-intervention, and six-month follow-up. RESULTS: Patients randomized to the d3RP-NF2 program, but not to the control condition, experienced significant decreases on both measures from baseline to post-test, which were maintained at follow-up (within group tests). However, improvements following the d3RP-NF2 program was not significantly higher than those observed in the control group (between group tests). CONCLUSION: Results provide the first evidence of improvement in symptoms of depression and perceived stress among deaf patients living with NF2 who participate in a virtual mind-body program.

The relationship between patients' perception of the effects of neurofibromatosis type 2 and the domains of the Short Form-36.

OBJECTIVES: To investigate the relationship between those issues concerning quality of life in patients with neurofibromatosis type 2 (NF2) as identified by the closed set NF2 questionnaire and the eight norm-based measures and the physical component summary (PCS) and mental component summary (MCS) scores of the Short Form-36 (SF-36) Questionnaire. DESIGN: Postal questionnaire study. SETTING: Questionnaires sent to subjects' home addresses. PARTICIPANTS: Eighty-seven adult subjects under the care of the Manchester Multidisciplinary NF2 Clinic were invited to participate. MAIN OUTCOME MEASURES: Sixty-two (71%) completed sets of closed set NF2 questionnaires and SF-36 questionnaires were returned. RESULTS: Subjects with NF2 scored less than the norm of 50 on both the physical component summary and mental component summary scores and the eight individual norm-based measures of the Short Form-36 questionnaire. Correlations (using Kendall's tau) were examined between patients' perceptions of their severity of difficulty with the following activities and the eight norm-based measures and the physical component summary and mental component summary scores of the Short Form-36 questionnaire: Communicating with spouse/significant other (N = 61). The correlation coefficients were significant at the 0.01 level for the mental component summary score, together with three of the norm-based scores [vitality (VT), social functioning and role emotional]. Social communication (N = 62). All 10 correlations were significant at the 0.01 or 0.001 level. Balance (N = 59). All 10 correlations were highly significant at the P < 0.001 level. Hearing difficulties (N = 61). All correlations were significant at either the 0.01 level or less apart from the mental component summary score and three of the norm-based scores (role physical, VT and mental health). Mood change (N = 61). All correlations were significant at the 0.01 level or less, apart from one norm-based score (role physical). CONCLUSIONS: The Short Form-36 questionnaire has allowed us to relate patients' perceptions of their difficulties, as identified by the closed set NF2 questionnaire, to the physical and mental domains measured by this validated and widely used scale, and has provided further insight into areas of functioning affected by NF2.

Social Independence of Patients with Neurofibromatosis Type 2 in Japan: Analysis of a National Registry of Patients Receiving Medical Expense Subsidies, 2004-2013.

Although it is important for patients with neurofibromatosis type 2 (NF2) to live independently and maintain good quality of life (QOL), no study has examined the social independence status in this patient population. This study aimed to examine the state of social independence and its contributing factors in patients with NF2 using data from a national registry in Japan during the past decade. A database provided by the Ministry of Health, Labour and Welfare of Japan that contained information about all patients with newly submitted claims for medical expense subsidies for NF2 in Japan between fiscal years 2004 and 2013 was analyzed. Individuals aged 6 to 64 years were deemed eligible for the present study. Categories of "employed," "studying," and "housekeeping" were classified as "socially independent." Multivariate logistic regression analysis was performed to examine associations between demographic variables, neurological features, and social independence status. Of 334 participants, 79% were socially independent at the time of registration. Socially dependent participants had more neurological features than those who were socially independent, whereas sex, age, and family history had no significant associations with social independence status. Multivariate logistic regression analysis revealed that participants with bilateral hearing loss, unilateral hearing loss, blindness, hemiplegia, or seizures had significantly higher odd ratios for being socially dependent compared to participants without these features. Our findings, which suggest that these neurological features could restrict social independence, could contribute to the maintenance of better social functioning and QOL in patients with NF2.

Psychological follow-up care of neurofibromatosis type 2 patients and their relatives.

Neurofibromatosis type 2 (NF2) confronts patients and their relatives with the dual issue of a progressive disease and disability. Deafness creates a brutal rupture in the patients' course of life, and other disabilities often follow in addition, that further deteriorates their quality of life. Hearing rehabilitation, via a cochlear implant and auditory brainstem implant, attempts to reduce the feeling of isolation and suffering due to communication impairment. A NF2-specific quality of life questionnaire not only helps to evaluate the impact of the disease but it is also useful therapy proposals (treatment, auditory implants). This may contribute to improve the quality of care for patients and their families. Within the multidisciplinary NF2 team, the psychologist offers constant listening of patients, and their suffering at each stage of the disease, that takes into account the life context in which the disease occurs, thus playing a major role in the patient care offered.

'Compassionate use' protocol for auditory brainstem implantation in neurofibromatosis type 2: Early House Ear Institute experience.

OBJECTIVE: To report the preliminary outcomes of auditory brainstem implantation (ABI) under a compassionate use protocol for two ABI devices that are not approved by the US Food and Drug Administration. METHODS: A retrospective review was performed of neurofibromatosis type 2 (NF2) patients who underwent microsurgery for vestibular schwannoma (VS) and placement of either the Cochlear ABI541 or Med-El Synchrony ABIs. Peri-operative and device- related complications were reviewed. Audiometric performance was also evaluated. RESULTS: Seven patients received either the Cochlear ABI541 (6) or the Med-El Synchrony ABI (1) after the resection of VS. No device or patient-related complications occurred to date. Surgical times and early audiological performance are similar to our previous experience with the Cochlear ABI24 device. CONCLUSIONS: Early experience with the Cochlear ABI541 and Med-El Synchrony ABI devices under a compassionate use protocol suggest that both devices are safe with comparable utility to the Cochlear ABI24 device.

Health-related Quality of Life of Individuals With Neurofibromatosis Type 2: Results From the NF2 Natural History Study.

OBJECTIVE: To explore health-related quality of life (HRQoL) reported by individuals with neurofibromatosis type 2 (NF2) and to assess for correlations between HRQoL and objective measures of disease manifestations. STUDY DESIGN: Prospective observational study. SETTING: Seven international NF2 centers. SUBJECTS: Eighty-one individuals with NF2, 73 adults (>18 years) and 8 children/adolescents (10-17 years). OUTCOME MEASURES: Quality of life was measured by Short Form-36 (SF-36) norm-based scores. Objective clinical measures were hearing (categorized by word-recognition scores), facial function (categorized by the House-Brackmann scale) and the volume of subjects' larger vestibular schwannoma (VS). RESULTS: At baseline, adults showed significant deficits in all but two subscales of the SF-36 compared with age- and gender-adjusted United States population norms. In linear regression models including age, gender, inheritance status, hearing, facial weakness and VS volume, demographic and functional measures showed no relationship to any SF-36 subscale. Larger baseline VS volume was significantly related to reduced physical role performance, reduced mental health, and increased pain (p < 0.05). In bivariate analysis, previous VS surgery was not significantly associated with baseline HRQoL; receipt of VS surgery or tumor growth during the observation period was not significantly associated with changes in HRQoL. CONCLUSION: NF2 patients report reduced HRQoL in physical, social, and mental domains, but this was not significantly related to objective measures of hearing or facial functioning. Larger baseline VS volume negatively impacted patient-reported HRQoL whereas VS surgery or tumor growth did not. Future studies should explore the relationship between tumor volume and HRQoL and psychosocial factors that may moderate this relationship.

Neurofibromatosis type 2-living with the complications: a case study.

Neurofibromatosis is a disease caused by a chromosomal defect that can occur spontaneously or be inherited. The disease is grossly disfiguring and carries with it significant psychological sequelae. It is characterized by tumors on nerve sheaths that can arise anywhere in the body. The rate and frequency of occurrence is unpredictable. More than nine different types of neurofibromatosis have been identified, but other than types 1 and 2, they are quite rare. All types of neurofibromatosis persist for a lifetime, so nurses from different backgrounds may encounter such a patient for various reasons. Nursing care should focus not only on the medical issues the patient presents with, but also on the psychosocial needs that may arise.

Rehabilitation of hearing and communication functions in patients with NF2.

Most patients with neurofibromatosis type 2 (NF2) lose hearing either spontaneously or after removal of their neurofibromas. The patient may benefit from conventional hearing aids if, due to modern microsurgery and intraoperative monitoring the integrity of the cochlea and the 8th nerve is preserved. With lost auditory function but preserved electrical stimulibility of the 8th nerve a cochlear implant may be appropriate. But if the patients have no remaining 8th nerve to stimulate, there is no benefit from cochlear implants. Until some years ago, vibrotactile aids, lip-reading, and sign language have been the only communication modes available to these patients. With auditory brain stem implants it is now possible to bypass both the cochlea and the 8th nerve and to stimulate the cochlear nucleus directly. Stimulation of the devices produces useful auditory sensations in almost all patients. Testing of perceptual performance indicated significant benefit from the device for communication purposes, including sound-only sentence recognition scores and the ability to converse on the telephone. Also lip-reading is significantly improved with brain stem implants. The successful work of an auditory brainstem program center depends very much on the close interdisciplinary collaboration between the Departments of Neurosurgery and ENT-surgery. In the future new developments like speech processing strategies and new designed electrodes accessing the complex tonotopic organization of the cochlear nucleus may further improve rehabilitation in these patients who would have been deaf some years ago.

Longitudinal evaluation of quality of life in 288 patients with neurofibromatosis 2.

Advances in molecular biology have resulted in novel therapy for neurofibromatosis 2-related (NF2) tumours, highlighting the need for robust outcome measures. The disease-focused NF2 impact on quality of life (NFTI-QOL) patient questionnaire was assessed as an outcome measure for treatment in a multi-centre study. NFTI-QOL was related to clinician-rated severity (ClinSev) and genetic severity (GenSev) over repeated visits. Data were evaluated for 288 NF2 patients (n = 464 visits) attending the English national NF2 clinics from 2010 to 2012. The male-to-female ratio was equal and the mean age was 42.2 (SD 17.8) years. The analysis included NFTI-QOL eight-item score, ClinSev graded as mild, moderate, or severe, and GenSev as a rank order of the number of NF2 mutations (graded as mild, moderate, severe). The mean (SD) 8.7 (5.4) score for NFTI-QOL for either a first visit or all visits 9.2 (5.4) was similar to the published norm of 9.4 (5.5), with no significant relationships with age or gender. NFTI-QOL internal reliability was good, with a Cronbach's alpha score of 0.85 and test re-test reliability r = 0.84. NFTI related to ClinSev (r = 0.41, p < 0.001; r = 0.46 for all visits), but weakly to GenSev (r = 0.16, p < 0.05; r = 0.15 for all visits). ClinSev related to GenSev (r = 0.41, p < 0.001; r = 0.42 for all visits). NFTI-QOL showed a good reliability and ability to detect significant longitudinal changes in the QOL of individuals. The moderate relationships of NFTI-QOL with clinician- and genetic-rated severity suggest that NFTI-QOL taps into NF2 patient experiences that are not encompassed by ClinSev rating or genotype.

Importance of local support groups for acoustic neuroma and neurofibromatosis patients.

Local support groups are an important part of the support network for acoustic neuroma and neurofibromatosis patients. For many people, the local support group is the only place where they can make personal contact with other patients who have gone through a similar experience. This article specifically looks at the Acoustic Neuroma Association and Neurofibromatosis, Incorporated and describes how these organizations help individuals.

Use of a closed set questionnaire to measure primary and secondary effects of neurofibromatosis type 2.

OBJECTIVES: To identify the greatest difficulties reported by people affected by neurofibromatosis type 2, and to determine the relationship between the primary and secondary effects of the disease. DESIGN: Postal questionnaire study. SETTING: Questionnaire sent to subjects' home addresses. PARTICIPANTS: Eighty-seven adult patients under the care of the Manchester multidisciplinary neurofibromatosis type 2 team were invited to take part. MAIN OUTCOME MEASURE: The response rate was 62 out of 87 (71 per cent). RESULTS: Respondents' answers emphasised that their greatest problem was deafness, which resulted in communication difficulties with social contacts, close partners, family and friends. Correlation coefficients indicated a relationship between general mood changes and hearing difficulties, social communication problems, balance difficulties and mobility problems. Self-confidence was significantly related only to social communication problems. CONCLUSIONS: The use of a closed set neurofibromatosis type 2 questionnaire identified hearing problems and subsequent communication difficulties as the main problems faced by people with this condition.

Neurofibromatosis 2--a family journey.

Neurofibromatosis 2 (NF2) is a complex autosomal dominant genetic disorder, now recognized to occur as a result of a mutation on chromosome 22. It is estimated to affect one in every 40,000 individuals worldwide. NF2's clinical manifestations of bilateral vestibular schwannomas and multiple other nervous system tumours have far-reaching implications for patients and families diagnosed with this challenging disorder. Management of these families should occur at specialty centres with the ability to provide treatment of these tumours, if necessary, as well as to have access to genetic testing and counselling. Decisions should be made with the quality of life of each individual as the cornerstone of care: knowing when to and when not to intervene is essential. The Atlantic Lateral Skull Base Clinic in Halifax follows approximately 400 patients with unilateral vestibular schwannomas and other skull base lesions. Twelve NF2 families are followed in this clinic. Several of their amazing stories will be shared in this presentation. Much can be done to effectively manage NF2 and help patients and families live healthy, happy and productive lives.
