Mood and Cognition in MS: The Patient’s Challenges & Ours Rosalind Kalb, PhD Jean-Martin Charcot Second Lecture on Multiple Sclerosis, 1868 There is marked enfeeblement of the memory; conceptions are formed slowly; the intellectual and emotional faculties are blunted in their totality…. It is not rare to see them give way to foolish laughter for no cause, and sometimes, on the contrary, to melt into tears for no reason. Nor is it rare, amid this state of mental depression, to find psychic disorders arise which assume one or other of the classic forms of mental alienation. Multiple Sclerosis: A [Very] Brief Overview What does MS look like? What does MS really look like? • Julia—a 35yo white married mother of 3 who is exhausted all the time and can’t drive because of vision problems and numbness in her feet • Jackson—a 25yo African-American man who stopped working because he can’t control his bladder or remember what he read in the morning paper • Maria—a 10yo Hispanic girl who falls down a lot and whose parents just told her she has MS • Loretta—a 47yo white single woman who moved into a nursing home because she can no longer care for herself • Geoff—a 24yo single white man who is severely depressed and worried about losing his job because of his MS diagnosis What MS Is: • MS is thought to be a disease of the immune system. • The primary targets of the immune attack are the myelin coating around the nerves in the central nervous system (CNS—brain, spinal cord, and optic nerves) and the nerve fibers themselves. • Its name comes from the scarring caused by inflammatory attacks at multiple sites in the central nervous system. What MS Is Not: • MS is not: Contagious Directly inherited Always severely disabling Fatal—except in fairly rare instances • Being diagnosed with MS is not a reason to: Stop working Stop doing things that one enjoys Not have children What causes MS? Genetic Predisposition Environmental Trigger Immune Attack Loss of myelin & nerve fiber What happens in MS? “Activated” T cells... ...cross the blood-brain barrier… …launch attack on myelin & nerve fibers... …to obstruct nerve signals myelinated nerve fiber myelinated nerve fiber What happens to the myelin and nerve fibers? Who gets MS? • • • • Usually diagnosed between 20 and 50 Occasionally diagnosed in young children and older adults More common in women than men (2-3:1) Most common in those of Northern European ancestry More common in Caucasians than Hispanics or African Americans; rare among Asians More common in temperate areas (further from the equator) Why does a person get MS? • • • We do not know why one person gets MS and another does not. We do not know of anything: The person did to cause MS. The person could have done to prevent it. There is no way to predict who will get it and who will not. What is the genetic factor? • • The risk of getting MS is approximately: 1/750 for the general population 1/40 for person with a close relative with MS 1/4 for an identical twin 20% of people with MS have a blood relative with MS The risk is higher in any family in which there are several family members with the disease (aka multiplex families) What are possible symptoms? • Fatigue (most common) • Bladder/bowel dysfunction • Sensory problems (numbness, tingling) • Vision problems • Pain (neurogenic) • Sexual problems • Breathing difficulties • Dizziness/vertigo • • • • Balance problems Weakness Stiffness (spasticity) Speech/swallowing problems • Tremor • Emotional changes • Cognitive problems Our focus today Visible to others How is MS treated? • While we continue to look for the cure, MS treatment needs to be comprehensive and interdisciplinary: Treating relapses (aka exacerbations, flare-ups, attacks) Slowing disease progression Managing symptoms Maintaining/improving function Enhancing quality of life for individuals and their families Who is on the MS “Treatment Team”? • • • • • • • • • • • • Neurologist Nurse Physiatrist Physical therapist Occupational therapist Speech/language pathologist Neuropsychologist Social worker/Care manager Psychotherapist Psychiatrist/psychiatric nurse practitioner Urologist Neuro-ophthalmologist It takes a village…. Primary Challenges for People Living with MS • • • • • • Chronicity—most will live with MS for decades Unpredictability—each person’s outcome is uncertain Change and Loss—most will need to grieve over major changes in their lives Expense—large direct and indirect costs Multiple Choices with no “correct” answers—treatments, disclosure, employment, family planning Risk Tolerance—varies among family members Contrasting Then and Now THEN NOW • “Diagnose & Adios” • • “You should go home and rest.” • “Women with MS should never have children • • “There is a lot we can do to manage your MS.” “People with MS can continue to work as long as they want to and feel able.” Women and men with MS can be happy parents of healthy kids.” So what do we know about MS? • • • • • • MS is a chronic, unpredictable disease. The cause is still unknown. MS affects each person differently; symptoms vary widely. MS is not fatal, contagious, directly inherited, or always disabling. Early diagnosis and treatment are important: Significant, irreversible damage can occur early on. Treatment reduces the number of relapses and may slow progression. Treatment includes: attack management, symptom management, disease modification, rehabilitation, emotional support. Mood Changes in MS Why are mood issues so important? • • • • • • Affect cognitive function Compromise quality of life Are associated with time lost from work Interfere with self-care/adherence to treatment Adversely affect relationships May be triggered by medications Depression—Setting the Stage1 • Depression Is more common in MS than in other chronic conditions. Is under-diagnosed and under-treated in MS patients. Impacts quality of life Interferes with a person’s ability to participate actively in his or her own MS care Impacts cognition (and vice versa) Is the greatest risk factor for suicide 1Feinstein, 2007 Prevalence of Depression in MS • Lifetime prevalence estimates range from 20-50% in clinic populations, with a similarly high rate in community samples.1 • Depression can occur at any time over the disease course. • People are at greatest risk for depression at major transition points:3 Following the diagnosis Following significant loss of function, departure from the workforce 1 Minden & Schiffer, 1990; Patten et al., 2003; 2Feinstein, 2007 Meet Joseph • • • • • 60 yo man with SPMS Married with two children Employed full-time as a college professor Triplegic Low-key, creative, warm, wry sense of humor Etiology of Depression in MS • Evidence points to a multifactorial etiology1 Brain pathology2,3 Psychosocial factors: • Unpredictability • Psychosocial stressors (marital problems; economic pressures, etc.) • Emotion-centered coping style4 • Learned helplessness vs. self-efficacy Abnormalities in the hypothalamic-pituitaryadrenal axis5 1Feinstein, 1995; 2Gold et al, 2010; 3Feinstein et al, 2004; 4Lynch et al., 2001; 5Wei & Lightman, 1997 Diagnosis of Depression in MS: The Challenges • Of 9 DSM-IV symptoms of depression, 4 are symptoms of MS1 Depressed mood most of the day nearly every day Markedly diminished pleasure in most or all activities Significant weight change (>5% up or down in a month) Inability to sleep or sleeping too much Motor agitation or significant slowing Fatigue or loss of energy Problems with thinking or concentrating Feelings of worthlessness/excessive guilt Recurrent thoughts of death 1Mohr et al., 1997 Diagnosis of Depression in MS: The Challenges, cont’d • Patients may be reluctant to report mood changes • Depression in MS often presents with irritability/frustration rather than the more typical withdrawal, apathy, and guilt1 • The common – but incorrect – assumption that it is “normal” for a person with a devastating chronic illness to be depressed • Depression can be difficult to distinguish from the grieving process that is part of life with MS2 1Minden et al., 1987; Feinstein & Feinstein; 2001; 2Kalb & Miller, 2008 What is normal grieving in MS? Kalb, 2008 Undiagnosed Depression: The Consequences • The result of these challenges is that many people with MS are living with an unnecessary amount of emotional pain, a reduced quality of life, and a greatly increased risk of suicide:1 In one study, two-thirds of MS patients with depression within a neurology clinic received no antidepressant treatment.2 Of those who were treated, only 25% were given an adequate dose. 1Feinstein, 2007; Sadovnick et al., 1991; Stenager & Stenager, 1992; 2Mohr et al., 2006 Suicide among Patients with MS • Suicide is more common in MS than in other neurological disorders.1 Swedish epidemiological study: significantly elevated risk of suicide in MS, particularly in males and those diagnosed before age 30.2 Canadian review of death certificates (1972-1988): suicide listed as cause of death in 15% of MS clinic attendees (7.5x greater than age-matched population).3 • Anxiety co-morbid with depression increases the risk for self-harm.4 1Stenager & Stenager, 1992; 2Stenager et al., 1992; 3Sadovnick et al., 1991; 4Feinstein et al., 1999 Tools for Assessing Depression in MS • • • Beck Depression Inventory (BDI) Beck Fast Screen for Medically Ill Patients (B-FS)* Hamilton Rating Scale for Depression (HDRS) [http://healthnet.umassmed.edu/mhealth/HAMD.pdf] • Psychiatric interview *Recommended by the Goldman Consensus Statement on Depression in Multiple Sclerosis (Goldman Consensus Group, 2005) Assessment Tools, cont’d • Two-question screening tool validated in MS1 260 MS patients screened using the MDD module of the DSM-IV Structured Clinical Interview Each participant also given two screening questions: 1. During the past two weeks, have you often been bothered by feeling down, depressed, or hopeless? 2. During the past two weeks, have you often been bothered by little interest or pleasure in doing things? Using at least one affirmative response on either question as the criterion identified 98.5% of patients meeting the criteria for MDD based on the structured diagnostic interview. 1Mohr et al., 2007 Depression: Treatment Recommendations • • • Psychotherapy + antidepressant medication is the treatment of choice1 Cognitive behavior therapy Psychoeducation (problem-focused coping skills)2 SSRI antidepressants Exercise3 ECT is recommended under limited circumstances4 Note: Support groups/chat rooms/bulletin boards are not adequate for treating significant depression 1Feinstein, 2007; Mohr et al., 2001b; 2Dennison et al., 2009; Goretti et al., 2009; 3 Dalgas et al., 2010; Stroud & Minahan, 2009; Petajan et al., 1996; 4Feinstein, 2007 Challenges to Treating Depression in MS • • • • • 1Mohr Patients’ resistance to treatment (“I take enough pills already!”) Neurologists’ lack of time/lack of training May require unusual/unexpected antidepressant dosages1 Non-adherence because of side effects (Rates of sexual dysfunction may be as high as 70% in a population that already experiences significant sexual dysfunction)2 Insufficient number of psychiatrists who are interested/accessible/covered et al., 2006; 2Feinstein, 2007; Zorzon et al., 2001 Meet Cassandra • • • • • • • 43 yo woman with PPMS Dynamic, funny, and smart Employed in a high-power job In a committed relationship Gradually increasing mobility impairment Responded so well to medication that she thought she didn’t need it any more—3 times Mood stabilized on maintenance dose Meet Anna • • • • • • • • 49 yo woman diagnosed with RRMS Employed as a teacher In a committed relationship Minimally physically disabled Bubbly, motivated, creative, clingy, dependent Became depressed following the diagnosis Pressured by her friends to seek treatment Successfully treated with antidepressant medication (“happy pills”) and intermittent psychotherapy for past 15 years So, what is the reality in MS? • • • • Depression in general tends to be under-diagnosed. Two-thirds of MS patients with major depression within neurological clinics receive no antidepressant treatment. Three-quarters of those treated are given an inadequate dose. Many people with MS are living with more distress and discomfort than they need to. Other Emotional Disorders in MS • • • • • Bipolar disorder Mood swings Anxiety Pseudobulbar affect Euphoria What do we know about bipolar disorder in MS? • • • • Relatively rare in MS, but more common than in the general population1,2,3 May share a common genetic predisposition with MS Likely related to white matter changes Responds to standard treatment (mood stabilizers + antipsychotic medication as needed) Steroid Alert 1Feinstein, 2007; 2Hutchinson et al., 1993; 3Schiffer et al., 1986 What do we know about mood swings in MS? • • • • • Moderate to severe shifts in mood may occur May shift between happiness, sadness, irritability, and/or rage Affects self-esteem and the sense of personal control Strains relationships at home and at work May be treated with a combination of psychotherapy and mood-stabilizing medications Steroid Alert Meet Norman • • • • • 55 yo man diagnosed with PPMS Minimally physically-disabled Married with two children Professional retired because of MS fatigue Warm, funny, feisty, irritable, moody One Child’s Description of MS Moods Anxiety in People Living with MS • Anxiety is more common than depression, especially among females, particularly right after diagnosis.1 • Like depression, anxiety is under-diagnosed and under-treated. • Anxiety is the best predictor of excessive alcohol consumption in people with MS.2 • Lifetime prevalence of generalized anxiety disorder in MS patients found to be 18.6% vs. 5.1% in general population.3 1Feinstein et al., 1999; Zorzon et al., 2001; 2Quesnel & Feinstein, 2004; 3Korostil & Feinstein, 2007 Pseudobulbar Affect (PBA) in MS • Characterized by episodes of uncontrolled laughing and or crying1 Inappropriate to both external circumstances and internal mood states • PBA may be mediated by damaged to the prefrontal cortex2 • Occurs in approximately 10% of MS patients2 • Generally associated with longer disease course, greater disability, and more cognitive impairment2 1Poeck, 1969; 2Feinstein et al., 1997 PBA, cont’d • • 1Schiffer Has been treated successfully with amitriptyline1 and SSRI antidepressants2 Neudexta® (dextromethorphan + quinidine) approved in 2010 to treat PBA3 & Pope, 1985; 2Seliger et al., 1989; 3Pioro et al., 2010 Euphoria in MS • • • • • • Once thought to be a hallmark of MS Persistent unrealistic optimism in spite of harsh realities and lack of insight Fixed rather than fluctuating—like a personality change Associated with progressive course, widespread lesions on MRI, significant cognitive impairment Devastating for families No treatment available Meet Erica • • • • • • 30 yo woman with SPMS Diagnosed with RRMS at age 14 In a long-term committed relationship Initial symptoms were cognitive changes that progressed rapidly Today, minimal physical symptoms but unable to function/live independently because of cognitive limitations Warm, cheerful, unconcerned about her status and future Take-Aways about Common Mood Issues • • • • • Significantly affect quality of life and healthcare May be related to disease process itself and/or altered life circumstances May overlap with other MS symptoms Are often under-diagnosed or mis-diagnosed Respond best to medication + counseling Depression and anxiety are more common in caregivers as well Cognitive Changes in MS Cognition and Other Disease Characteristics1 • Cognitive function correlates with number of lesions and lesion area on MRI, as well as brain atrophy. • Cognitive dysfunction can occur at any time but is more common later in the disease. • Cognitive dysfunction can occur with any disease course, but is slightly more likely in progressive MS. • Being in an exacerbation is a risk factor for cognitive dysfunction. • Depression can worsen cognition, particularly executive functions. 1Feinstein, 2007; LaRocca & Kalb, 2006 Prevalence of Cognitive Changes1 Severity of Cognitive Changes in Multiple Sclerosis None 50% Mild 40% Moderate to severe 10% 1LaRocca & Kalb, 2006 Impact of Cognitive Impairment on Employment1 45 40 % Employed 35 30 25 20 15 10 5 0 1Rao et al. 1991 Impaired Not Impaired Cognitive Functions Affected in MS1 • • • • Memory - acquisition and retrieval Attention and concentration Speed of information processing Executive Functions (planning, prioritizing, organizing, decision-making) • Visual/spatial organization • Verbal fluency - word finding 1DeLuca, 2006 Cognitive Functions Unaffected in MS1 • • • • • 1DeLuca, General intellect Long-term (remote) memory Recognition memory Conversational skill Reading comprehension 2006 The Psychosocial Impact of Cognitive Changes1 • The ability to think, remember, and reason is central to a person’s identity. Changes in cognitive abilities: Threaten the sense of self Damage self-esteem and self-confidence • Cognitive abilities impact interactions with others. • Cognitive impairments: Alter communication patterns Impact other people’s perceptions Interfere with role performance Affect the balance and intimacy in a partnership Have an interrelationship with depression 1Kalb, 2006 Guidelines for Treatment (for now)1 • Symptomatic Treatments – slow progress Not much of real value has emerged; as of 2012 no agents have demonstrated efficacy in controlled clinical trials • Disease Modifying Agents – may be most important Modest results so far, but if they can slow or halt accumulation of cerebral lesions . . . • Cognitive Rehabilitation – common-sense help Disappointing data thus far but common-sense points to compensatory measures as best strategy Address affective and social issues related to MS Implications for patient care Even mild cognitive dysfunction can impact treatment: • Your patients may not: Show up on time for appointments Follow complex explanations Remember what they’ve been told Follow through on treatment plans • You may want to: Provide informational brochures Provide appointment reminders Write down specific instructions Remind patients to write down their questions Invite patients to bring a family member or friend to appointments Multiple Sclerosis Neuropsychological Screening Questionnaire (MSNQ)1 • 15-item self-report questionnaire (http://mscare.org/cmsc/images/pdf/MSNQ.pdf) Includes versions for both patient and informant Takes approximately 5 minutes Reliable and predicts neuropsychological impairment • Both self- and informant reports correlated with cognitive dysfunction and depression scales, however: • Self-reports may be exaggerated in depressed patients • Self-reports may under-estimate impairment in severely impaired patients Benedict et al., 2003; Benedict et al., 2004 NMSS Resources for Clinicians • MS Clinical Care Network (www.nationalMSsociety.org/MSClinicalCare; healthprof_info@nmss.org; Clinical consultations with MS specialists Literature search services Professional publications (Clinical Bulletins; Expert Opinion Papers; Talking with Your MS Patients about Difficult Topics; Pamela Cavallo Education Series for nurses, rehab professionals, mental health professionals, and pharmacists Professional Education Programs (Nursing, Rehab, Mental Health) Consultation on insurance and long-term care issues NMSS Resources for Your Patients • • • • • • • 40+ chapters around the country Newly-designed Web site (www.nationalmssociety.org) Access to information, referral, support (1-800-344-4867) Educational programs (in-person, online) Support programs (self-help groups, peer and professional counseling, friendly visitors) Consultation (legal, employment, insurance, long-term care Financial assistance
