I want to die in my sleep like my grandfather,
not like the people kicking and screaming in the
backseat of his car. Sue McKay Geriatric
Psychiatrist

  • 73 year old woman who presents with 2 month
    history of tearfulness, loss of energy, apathy,
    inability to get out of bed in the morning, and
    insomnia with early morning awakenings. She
    describes increasing anxiety, an inability to
    cope, forgetfulness, problems reading or even
    watching TV, a 30 lb weight loss and feels very
    constipated.
  • She expresses a concern that something is wrong
    with her stomach. Her lower back has also been
    bothering her more.
  • She lost her husband 8 months ago and one of her
    children a little over 1 year ago.
  • She has a remote history of resected breast
    cancer and a more recent history of thyroid
    cancer which was resected 3 years ago. She also
    has a history of atrial fibrillation. She has no
    past psychiatric history and has always been able
    to cope with difficulties until recently.
  • She is on coumadin and a beta blocker.

7
  • What is in your differential diagnosis?
  • What kind of investigations would you order?
  • Assuming you believe her to be depressed what
    would be your plan of treatment?
  • Is there a reason for suggesting one
    antidepressant over another?
  • Assuming she does not have any response to
    treatment after 3 weeks what would you do?

8
  • Psychological
  • Depressed mood
  • Loss of interest or pleasure
  • Feeling worthless or guilty
  • Problems thinking or concentrating
  • Suicidal ideas or plans
  • Vegetative
  • Change in appetite or weight
  • Change in sleep
  • Loss of energy
  • Psychomotor changes
  • Associated (non-DSM IV)
  • Anxiety (brooding, obsessive ruminations) or
    phobias
  • Irritability
  • Excessive worry about physical health
  • Pain
  • Tearfulness

  • BIO
  • SIMILAR EFFICACY
  • SSRIs (equal DBPC trials (70/40 D/P response),
    SNRIs (?lower remission rates, faster response),
    SARIs, NaSSAs, TCAs, MAOIs, RIMAs, NDRIs.
    COMPARE pooled n-33 DBPC remission rates
    SSRI/SNRI/P 35/41/24 n3355/3410/932
    Nemeroff 2004 WJP. Comparison trials have higher
    response and remission rates.
  • ADEQUATE TRIALS
  • Adequate trial 4-6 weeks (look for some response
    _at_ 2 weeks as a predictor of success). Switching
    amongst the same class may also work. Effective
    (Response 70 w 1st, 70 w 2nd, 90 overall).
    BUT 50 discontinue in first 3/12, lt30 complete
    full course of tx. Watch for adherence.
  • SPECIAL POPULATIONS
  • Some evidence for gt efficacy in severe depression
    with TCAs (Clomipramine study group although
    HAMD favors sedative ADs over celexa).
  • Atypical features Better efficacy with MAOIs.
    Recurrent FHx of BAD consider Li.
  • Psychotic features ECT vs add AAP to
    antidepressant.
  • ECT (particularly psychotic depression 95 RR).
  • Consider especially if situation is urgent, not
    eating.drinking, taking medication, suicidal,
    medication intolerance

13
  • AUGMENTATION
  • Augmentation Li (11 w TCAs studies (n135), RR
    52, ? w SSRIs), T3 (w TCAs), MPH, tryptophan,
    low dose atypical neuroleptics (Nemeroff JCP
    2005). Consider also DA agonists-pramipexole
    (Aiken JCP 2007), strattera, pindolol, buspar,
    tryptophan, lamictal. Combos Buproprion (2D6
    inhibition), NaSSAs (Carpenter 99, Debonnel
    2000), SARIs (watch for SS), SSRI w Des (Nelson
    99, 2000). Caution with MAOIs and SSRIs. MAOI
    can be combined with a noradrenergic agent b/o
    COMT. STARD augmentation in TRD. See next
    slide.
  • MEDICALLY UNWELL
  • Comorbid medical conditions, consider stimulants,
    which are relatively safe and work faster.
    Methylphenidate, dextroamphetamine, and modafinil
    (less inc in BP, also helpful with narcolepsy).
  • NEW OPTIONS
  • Novel agents on the horizon duloxetine (balanced
    dual 5HT/NA agent with affects on pain),
    agomelatine (agonist MT1/MT2 antagonist 5HT2C
    helps with sleep few ASEs), Ketamine, Selegiline
    transdermal system (STS), released this year in
    the US, reduced risk of dietary restrictions at
    lower doses compared with standard MAOIs.

14
  • Rates of recovery vary with duration of
    unremitted symptoms
  • Kindling
  • Decrease in precipitators
  • Number of episodes increases risk of reoccurence

15
  • Thase-Rush Criteria
  • Stage 1 Failure of an adequate trial of 1 class
    of major antidepressant
  • Stage 2 Failure of adequate trials of 2
    distinctly different classes of antidepressant
  • Stage 3 Stage 2 plus failure of a third class of
    antidepressant, including a tricyclic
    antidepressant (TCA)
  • Stage 4 Stage 3 plus failure of an adequate
    trial of a monoamine oxidase inhibitor (MAOI)
  • Stage 5 Stage 4 plus failure of an adequate
    course of electroconvulsive therapy (ECT)
  • Options
  • Switch antidepressants
  • Different or same class
  • Augmentation
  • Another antidepressant
  • Mood stabilizers Li, Lamictal
  • Atypical antipsychotic
  • Dopaminergic agents
  • Stimulants
  • Psychotherapy
  • ECT
  • Experimental TMS, VNS
  • See slide on reasons for tx resistance

  • In the Elderly
  • Community studies
  • have shown that 25 of elderly persons report
    having depressive symptoms, but only 1 to 9
    meet the criteria for major depression Lebowitz
    BD JAMA 1997.
  • Prevalence varies according to the population.
  • Higher prevalence rates are reported in the
    hospitalized elderly (36 to 46), those who
    receive homecare 13.5 (Hybels Clinics in Ger Med
    2003) and
  • those in long-term care facilities (10 to 22)
    Teresi J. Soc Psychiatry Psychiatr Epidemiol 2001

20
  • More likely to have somatic complaints, anxious,
    melancholic and psychotic features. Therefore
    ECT often used and is effective.
  • Similar response rates (although may take longer
    to tx), high relapse rates. Only 10-20 are tx
    resistant. With aging, more frequent episodes
    and longer untreated episodes (duration to
    spontaneous remission is longer) or may change to
    chronic course.
  • May have comorbid cognitive impairments.
    Non-compliance and physical disability often lead
    to chronicity.
  • More often confronted by death, grief may be a
    complicating feature

21
  • Depression
  • Persistent mood state
  • Poor self esteem (from Mourning and Melancholia,
    Freud introjected lost object w negative assoc
    feelings experienced as part of self)
  • Fxnal impairment beyond 2/12
  • Suicidal thoughts with desire to die
  • Grief
  • Dysphoria, sadness comes in waves with marked
    fluctuation, often w triggers
  • No fxnal impairment gt 2/12
  • No psychomotor retardation, active suicidality,
    psychosis (although transient phen may occur)
  • Bowlby
  • Phases of Uncomplicated Grief (PSDR)
  • Acute despair/protest, denial (numbness,
    outbursts, anger)
  • Yearning / searching for deceased (restlessness,
    preoccupation w deceased)
  • Disorganization despair (going through the
    motions, withdrawn, apathetic)
  • Reorganization (can think of loved one w
    joy/sadness
  • Grief in Children
  • Protest, Despair, Detachment
  • Kubler Ross
  • 1) Shock/denial, 2) anger, 3) bargaining, 4)
    depression, 5) acceptance

  • The following is true regarding depression
  • it is a treatable condition that with
    antidepressants has a remision rate of 30-40 and
    response rates of 67-90
  • the neurotransmitters serotonin and noradrenaline
    are involved
  • c) Psychotherapy is effective in severe
    depression
  • d) an association between early life trauma,
    hippocampal atrophy and depression can be seen
  • it often presents with multi-system physical
    complaints
  • it is associated with coronary artery disease,
    stroke, diabetes, cancer, Parkinsons, and MS.
  • ECT should be considered only when all other
    treatments have failed

23
Depression in old age
  • Is more prevalent in women than men
  • Prevalence rates rise sharply with age
  • Is accompanied by a much lower suicide risk than
    in younger adults
  • Is unresponsive to treatment in half of cases.
  • Is often precipitated by a loss
  • Both b) and d)
  • Both a) and e)

24
Psychotic Depression
  • a) Is more frequent in elderly.
  • b) Remits with antidepressants in 50 of cases
  • c) Remits with antidepressants antipsychotics
    in 75 of cases
  • d) Responds and remits best with ECT
  • e) Should prompt thorough search for symptoms of
    bipolar illness in pt and family members.
  • f) All of the above except b)
  • g) All of the above except b) and c)

25
Which of the following are frequent reason
for consultation by elderly who have their first
depressive episode
MCQs
  • a) Nerves
  • b) Excessive fatigue
  • c) Hypersomnia (sleeping too much)
  • d) Digestive problems
  • e) Fear of Alzheimers disease

26
MCQs
  • a) Active suicidal ideation
  • b) Prominent psychotic symptoms
  • c) Crying spells when she thinks of her deceased
    husband.
  • d) Being less active socially
  • e) Being unable to attend to her usual daily

27
  • 76 year old who presents with decreased sleep,
    increased activity, mood lability with both
    tearful episodes and euphoria, 20 lb weight loss,
    irritability, circumstantiality, ruminations
    about perceived injustices in the past, and a
    concern over a conspiracy that involves his
    family physician, friends and neighbours.
  • He was started on Prednisone for a skin condition
    two weeks preceding these changes.
  • Because he is convinced he is invincible and his
    behavior started to include reckless and
    dangerous activities he was admitted to hospital.

  • BAD specifiers
  • Type I Mania
  • Type II No hx of mania but episodes of

29
  • B- Determine phase of illness MDE,M, ME, E
  • Mania start or optimize monotherapy
  • Li or VPA, consider augment w AP (particularly w
    psychotic features), benzo. If no response
    combine other (Li or VPA). Mixed or dysphoric
    (?comorbid subs abuse) VPA may be better.
    Usually depressive sx are residually present.
    Another option is OLZP (2 large RCTs- Tohen 10
    mg, AJP 1999, Tohen 15 mg AGP 2000) w comparable
    efficacy to Li, VPA, Haldol. gt than VPA in
    comparison trial. Risp and Zip studied in PCT as
    add ons to Li or VPA w efficacy comparable to
    HaldolgtPCB.
  • Depression do not start an antidepressant
    without a mood stabilizer. Lithium monotherapy
    should be considered.
  • Lithium (8 PCTs 79 response) or Lamotrigine
    (Calabrese JCP 1999 MADRS 200gt50mg/dgtPCB , n195
    BAD-I). AD monotherapy not recommended b/o
    switch /- rapid cycling. Buproprion (2
    controlled add on studies 1st efficacy to Des
    but less manic switch, RIMA (comparable to IMI w
    less ASE), Paxil 3 double blind add on studies,
    1st good responseadd on of other (ie. of either
    VPA or Li), no difference if Li gt 0.8, sim to
    Effexor but less manic switch. AAP improve
    depression subscales in tx of Mania and extension
    trials.

30
  • B- Determine phase of illness DE,M, ME,
  • Maintenance Only Lithium supported by RPCTs
    although some design limitations. One negative
    PC comparison trial w VPA (Bowden AGP 2000). VPA
    studied in comparison w Li but no PC.
  • Specific Meds Lithium (Cades disease for
    mania, depression, relapse prevention 5 PCTs gt25y
    ago), Epival (rapid cycling, dysphoric, mixed
    episode, efficacy in mania but prophylaxis data
    lacking). Alternatively monotherapy w AAP.
    Lamotrigine appears helpful w depression
    (Calabrese JCP 1999) , rapid cycling (BAD-II)
    (Calabrese JCP 2000), but not mania). Topimax
    (no PCT, studied as add on cf buproprion
    McIntyre Acta Neuropsychiatr 2000), GABApentin.
    OLZP and more atypical studies pending. Also
    consider Clozapine in tx resistant cases.
  • ECT for tx resistant acute mania or depression
    (particularly w psychotic features).

32
  • P- Establish therapeutic alliance, individual
    psychoed intervention, interpersonal and social
    rhythm therapy helps correct sleep which
    decreases relapse risk. Prelim studies suggest
    that CBT may help reduce depressive sx, improve
    longer term outcomes and adherence. Supportive
    therapy may also be helpful (social skills help,
    coping skills, problem solving.
  • S- Involve family. Family interventions and
    focused therapy can helping to accept illness,
    identifying precipitating stressors inside and
    outside of family, examining family interactions
    that produce stress in the pt, developing
    management plan these all lead to reduced
    relapse rates. Housing, work/vocational support.
    Collaborate to address comorbidity. Case
    management, ACT, rehab, should be considered.

33
  • More secondary mania (less often FHx).
  • More mixed/dysphoric features with irritability
    but lithium response rate similar in young and
    old. Longer acute episodes. Increased
    frequency, higher prevalence of neurological
    abnormalities
  • Less hyperactivity, grandiosity, less euphoria,
    flight of ideas although may have disorganization
    and circumstantiality as well as delusions.
  • Secondary Causes of Mania in Elderly

34
  • Which of the following is true of Bipolar
    disorder
  • Depression is the most debilitating and treatment
    resistant phase of the illness
  • Lithium has the best evidence for the treatment
    of depression, mania, suicide risk reduction and
    maintenance
  • Their exists double blind placebo controlled
    evidence for the use of Epival in depression and
    for the maintenance phase of the illness
  • Lamotrigine has been shown to be an effective
    antimanic agent
  • There is evidence for the use of atypical
    antipsychotics in mania
  • Olanzapine and Seroquel have been studied in a
    placebo controlled fashion for the depressive
    phase.
  • Clozapine can be used for treatment refractory
    cases

35
Compared to younger manic patients, elderly manic
patients seem to have
MCQs
  1. Less hyperactivity
  2. More mixed (depressive/manic) clinical
    presentations
  3. More disorganised speech with flight of ideas.
  4. More irritability and less euphoria
  5. Less paranoid delusions

  • Secondary anxiety disorders more common in
    elderly
  • Primary anxiety disorders, like personality
    disorders, generally do not have an onset in the
    elderly
  • High comorbidity with depression
  • Overally less common in the elderly.
  • Phobias and GAD are the most common. Panic
    disorder is relatively rare, less than the 1-3
    described in younger populations (Flint AJP
    1994).
  • Caution with anxiolytics
  • can cause paradoxical disinhibition
  • Diphenylhydramine (Benadryl), Dimenhydrinate
    (Gravol), Chlorpromazine, Amitriptyline, chloral
    hydrate and barbiturates are not good anxiolytics
    for older patients due to their side effects

  • a) It is more often secondary to another axis 1
    condition like depression or medical condition
  • b) Anxiolytics can worsen not only anxiety but
    can cause sleep disruption, falls, and MVAs.
  • c) Benzodiazepines are safe in the elderly

  • A 78-year-old widow who lives alone and whom you
    have seen infrequently is brought to your office
    by her daughter. Although the patient has no
    complaints, her daughter indicates that for the
    past 2 years she has become more forgetful. Her
    behaviour is repetitive, and she sometimes calls
    her daughter several times a day to ask the same
    question. The quality of her housework is
    beginning to decline (her house is untidy, food
    is left to spoil in the refrigerator, she is
    limiting food preparation to simple, familiar
    items, and she has to check recipes even for easy
    dishes). Her personal hygiene is also declining,
    and some bills are not being paid on time.

  • As her family physician you diagnosed Parkinsons
    disease and initiated L-Dopa. The L-Dopa helped
    with her motor symptoms. Periods of confusion
    became evident as were well formed visual
    hallucinations. Because of your suspicion of
    delirium and some urinary symptoms you treated
    her for a UTI.

    inappropriateness was negligible and quite
    embarassing for her family who feel she seems
    like a different person. Her language also has
    changed where she has experienced increasing
    difficulties speaking clearly. She often mutters
