About
This study will examine the effectiveness of a neuromyelitis optics spectrum disorder (NMOSD) specific Acceptance and Commitment Therapy (ACT) intervention at reducing anxiety and depression in individuals with NMOSD and their caregivers/loved ones and improving overall health outcomes in individuals with NMOSD.
Full description
Neuromyelitis optica spectrum disorder (NMOSD), also known as Devic disease, is an inflammatory disorder of the central nervous system. The primary symptom of NMOSD is attacks of inflammation and damage in the optic nerves and spinal cord. Such attacks may cause rapid onset of eye pain or blindness, limb weakness, numbness, or partial paralysis, shooting pain or tingling in the neck, back or abdomen, loss of bowel and bladder control, and prolonged nausea, vomiting or hiccups. These attacks may have periods of remission and relapse, with relapses most commonly occurring years to months apart. Monophasic NMO is a less common variant of NMOSD, and is characterized by a single, severe attack that may last days or weeks. When a patient is first diagnosed with NMOSD, it is unclear whether or not they will have relapses. The psychological burden of NMOSD is documented in the empirical literature, with a focus on experience of depression, pain, sexual dysfunction, sleep issues, stigma, and impact on partners.
Between 30% and 50% of individuals with NMOSD have been found to endorse clinically significant depressive symptoms on the Beck Depression Inventory. Compared with patients with Multiple Sclerosis (MS), NMOSD patients are twice as likely to receive a formal diagnosis of Recurrent Major Depressive Disorder.
Pain, bowel and bladder dysfunction, visual impairment, reduced sexual function, and inability to work, were found to most negatively impact emotional well-being and quality of life among people with NMOSD. It is estimated that chronic pain affects over 80% of NMOSD patients, including patients without recent relapse still commonly reporting moderate or severe pain. Pain severity is the strongest negative predictor of quality of life, and the most common symptom of concern voiced by patients to their physician.
Sexual dysfunction, specifically reduced libido, decreased orgasm and erectile dysfunction have been reported by 75% of males and 75% of females living with NMOSD.
Sleep disturbance is common in NMOSD, with 64% of NMOSD patients identified as poor sleepers, with correlations with anxiety, depression, pain, disability, and disease duration. Similarly, 71.4% of NMOSD patients endorsed fatigue, with correlations with sleep disturbance, depression, pain, and quality of life.
Further contributing to the psychological burden of life with NMOSD, 60% of patients reported being affected by NMOSD-related stigma. Embarrassment due to physical limitations, perceived exclusion, avoidance/ostracism, and blame for their illness were deemed the most impactful targets of stigma.
The psychological burden is also well-defined by patients with NMOSD and their loved ones in online forums, blogs, and social media. In addition to the domains cited in the literature, patients and loved ones often discuss anxiety, delayed diagnosis, physical disability and impact on relationships as hallmark characteristics of life with NMOSD. Despite the many studies suggesting that life with NMOSD is marred by many psychological stressors, including increased depression, there does not appear to be any psychosocial intervention to date to help patients and loved ones cope with this burden. Furthermore, narratives from patients across media describe profound psychological burdens that go untreated.
Given the prevalence of depression, stress, stigma, and physical impediments associated with NMOSD, it makes sense that patients and their loved ones would resort to avoidance-based coping (distraction with television, avoiding talking about illness, avoiding reminders of illness) to manage these issues. Compared with patients with multiple sclerosis, and with healthy controls, patients with NMOSD were more likely to use mental disengagement strategies, while both NMOSD and MS patients were more likely to use acceptance and behavioral disengagement strategies, compared with healthy controls. However, while avoidance-based coping may provide an effective short-term escape from the psychological burden of NMOSD, it is considered a maladaptive coping strategy in the longer term, as avoidance can be associated with medication nonadherence, missing clinic visits, failure to inform medical providers about symptoms, and can be associated with a paradoxical increase in depression and anxiety.
While the economic burden of NMOSD, including financial cost of treatments, loss of income due to disability, and associated financial pressure on caregiver/loved ones is well known, the psychological impact of NMOSD on caregivers and loved ones remains under-studied to date. Based on PHQ-9 score, 21.1% of loved ones of NMOSD patients were found to be experiencing mild, moderate, or moderately severe depressive symptoms. However, partners did not endorse clinically significant "burden", anxiety, or depression. Rather, partners endorsed pressure to take on new roles both inside and outside of the home, during NMOSD relapses, with both male and female partners identifying challenges related to gender role shift.
Partners endorsed limiting hobbies and activities to prioritize the patient's health, particularly during a relapse, along with frustration about accommodating NMOSD symptoms in public spaces, helplessness that they cannot "fix" their partner's problems, isolation due to lack of support, and anxiety about their partner's well-being and about their own health. Male partners reported "hardly expressing thoughts and feelings about NMOSD", and reported that prior to study participation, they had "never been asked how they feel about NMOSD." Lack of caregiver support and avoidance-based coping are associated with caregiver strain and burnout. Given the physical impediments associated with NMOSD, caregivers are often responsible for managing the patient's medication regimen and transporting patients to their infusion appointments. Caregiver burnout can understandably negatively impact patient treatment engagement.
Therefore, the investigators propose a caregiver-assisted, NMOSD-specific mental health intervention. Given physical limitations associated with NMOSD, and increased comfort with telehealth over the past few years, the investigators propose a telehealth-delivered intervention will be most accessible and effective. Acceptance and Commitment Therapy is one potential intervention for reducing internalizing symptoms, increasing purpose in life, and reducing avoidance-based coping among people with NMOSD and their caregiver loved ones. ACT is a "third wave" behavioral therapy which balances encouraging life changes in the service of one's values (purpose in life) with a strong acceptance component. This novel, experiential, contextual talk therapy is an empirically supported treatment for anxiety and depression, substance use, and has proven successful in managing chronic pain, somatic problems, HIV, Pancreatic Cancer and Cystic Fibrosis.
