Disturbi d’ansia
• Strettamente correlati al vissuto di malattia • Consapevolezza di avere una malattia
cronica,invalidante,imprevedibile • Vissuti di frustrazione e di pericolo per la
propria integrità fisica (carrozzina) • Vissuti negativi di affermazione del ruolo
familiare, lavorativo, sociale

Depression in MS: Prevalence • Depression is frequently
observed in MS patients (Patten et al., Can J Psych 2005)
• Associated with low quality of life, absence from work, and suicide (Goldman Consensus Group, Mult Scler 2005)
• Depression is not correlated with level of disability (Feinstein, Mult Scler 2011)
• What is the reason for the high prevalence of depression in MS?

Depressive Symptoms (or Depressive Syndromes)
in MS patients
• 5 - 20 % at MS onset
• 5 to 10 times more frequent than in HC or in chronic diseases
• Mild / moderate / severe (not related to MS severity)

IDENTIFICATION OF AFFECTIVE DISORDERS IN MS Shortcomings of Current “Real” Practice
• It has been estimated that as many as 50% of depressions may go underdetected during standard medical evaluation
• Patients’ behavior is often misinterpreted both by family members and physicians.
• Screening is unsystematic • Formal assessment of behavioral/affective
disturbance is infrequent. • Treatment is sporadic.

The effects of stressful life events on the course of MS
• 85% of clinical exacerbations associated with stressful life events in the 6 months before the relapse (Brown and Harris 1978,….)
• No association (Gasperini et al 1995; Nisipeanu and Korczyn,
1993; Sibley 1997) • A Metaanalysis by Mohr et (2004) concluded
on a consistent association between stressful life events and subsequent exacerbation in MS

The effects of stressful life events on the course of MS
• Methodological differences (retrospective vs prospective studies, clinical vs MRI)
• Definition of “Stressful event” • Severity of stressful event (non linear relationship
between severity of stress and relapses)
• Duration of Stressful event (acute vs chronic)
• Subjective vs Objective definition

“the vicious cycle”
Stressful events relapse level of disability, increase of stressful situations

The Temporal Model • Acute Stress Onset • Change from acute to chronic Stress Ø commonly marked by increased level of cortisol Ø glucocorticoid resistance Ø down regulation of glucocorticoid receptor number and
function Ø decrease in control over inflammation • Resolution of the stressor (reduction in cortisol
production represents a decrease in control over inflammation processes)

Acute Stress: the Mast Cell hypotesis

• Beta Endorfine
• Hypothalamo-pituitary-adrenal (HPA) axis hyperactivity

Interrelazione tra Sistema immunitario/ disturbo depressivo/sistema
serotoninergico ◆ Il trasportatore della Serotonina è coinvolto nella patogenesi della depressione (Stanley et al. 1982)
◆ TNF-α e IFN-γ possono aumentare la attività e la trascrizione del traspostatore della serotonina, che riveste un ruolo rilevante nelle terminazioni serotoninergiche (conseguente riduzione serotonina) (Blakely et al. 1991)
◆ L’ antidepressivo Rolipram, riduce la sintesi di TNF-α e IFN-γ e manifesta effetti preventivi nella EAE (Sommer et al. 1995)

ß-Endorfine
• Fattore che esercita un effetto inibitorio tonico sulla funzionalita’ del sistema immunitario.
• La concentrazione delle ß-Endorfine nelle cellule immunitarie è diminuita in patologie nelle quali il sistema immunitario è attivato.
• L’interleukina 1 iniettata nel ratto a livello intraventricolare aumenta la concentrazione di ß-Endorfine nei linfociti per coinvolgimento del CRH, catecolamine e serotonina (Sacerdote et al)

STRESS and DEPRESSION around

STRESS and DEPRESSION around MS Diagnosis
• Lack of correlation between anxiety symptoms and any particular distribution of MS lesions
• Stress is reactive to stressful events and not a symptom of the disease (Zorzon et al, 2001)
• Coping strategies (Problem or Emotion focused CS) may reduce psycological pressure and be useful to manage the demand of stressful situations
![Page 57: EMOTIONAL and AFFECTIVE Disturbances in MS - AINI - Home · " Riso e pianto patologico. Depression in MS: Prevalence ... • Stress is reactive to stressful events and not a symptom](https://reader031.vdocuments.mx/reader031/viewer/2022011808/5c6764b009d3f22d638bc81b/html5/thumbnails/57.jpg)
Stress-ProblemFocusedCopingStrategies-
MRI activity
The use of PF CS reduces stress perception as well as the risk of appearance of new MRI
lesions (Mohr et al 2002)

Other factors related to stress perception and effects in MS
• Health Locus of Control (internal or external) • Optimism (personality aspect) q Outcome expectancies q Efficacy expectancies q Unrealistic thinking
• Social support and adult attachment styles (secure vs avoidant stile)
• Age, marital life, gender and education

Reliable and valid information on MS
A better understanding of MS and treatments
A more active role in coping with the disease

Adverse effect of interferons? • Not mentioned in the Rice et al. Cochrane Review (2001) • Long history of problems with alpha interferons • Liberati (1990) – beta interferons safer? • Pliskin (1996) – emphasized dosing differences • In SPECTRIMS trial, depressive symptoms were no more
common in patients treated with IFN than in PL (Patten et al. 2002).
• The frequency of depression declined in RRMS patients followed for 1 year after onset of treatment with IFN (Feinstein et al 2002)
• The severity of depression was unchanged in patients treated with IFNbeta 1a (Zephir 2003).
• The suicide risk is unchanged during IFN treatment (Patten 2005)

Pharmacoterapy in MS with MDD Ø 260 patients with MS treated by 35 neurologists.
Ø 67 patients (25.8%) met the criteria for MDD
Ø Among the patients with MDD
– 65.6% received no antidepressant medication
– 4.7% received subthreshold doses from their neurologists
– 26.6% received doses at threshold
– 3.1% received doses exceeding threshold
Ø Depression was undertreated in this sample of patients
with comorbid MS and MDD Mohr 2006

DEPRESSION TREATMENT in MS patients
• Pharmacotherapy and psychotherapy of depression are more efficient than placebo (Mohr, 1999 ; Lamberg, 2001). – Comparison between both in large groups has not be done.
• Pharmacotherapy : few research on small samples on antidepressant pharmacotherapy of depression associated with MS.
• Psychotherapy : cognitive and behavioral therapy based on stress model (conscious strategies to cope with stressing events better than insight oriented therapy)

Non-pharmacologic therapy
µ Psychotherapies: µ Individual psychotherapy (Minden, 1992)
µ Group therapy: analytical (Barnes et la, 1954); supportive (Spielberg, 1980); insight oriented (Crawford and McIvor, 1985).
µ Cognitive-behavior therapy (Mohr et al, 2001). µ Supportive-expressive therapy (Mohr et al, 2001).
µ Telephone administered cognitive-behavior therapy over 8 weeks helped mood and adherence to interferon beta-1a (Mohr et al, 2000).

DEPRESSION TREATMENT IN Multiple Sclerosis
• Cognitive and behavioural therapies : active
coping strategies problem focussed are more efficient (facing the situation, action planning, looking for social support) than passive coping strategies emotion focussed
• Perceived social support is correlated with a good emotional adaptation in MS

Psychological interventions may improve the psychological and physical well being of individuals with MS • by treating mood disorders such as anxiety and depression
• by improving self-management and adherence, • by enhancing self efficacy and esteem, • by reducing stress, improving coping skills and general quality of life.
Aims of Psychological Interventions

• Psychological therapy on an individual basis may help individuals to develop skills to cope with emotions, and to find adjustment to MS diagnosis and symptoms.
• Group therapy is often used to decrease feelings of alienation, facilitate expression of emotions related to the disease, and provide peer support.
