current episode severity
17
Q
list specifiers listed in the DSM V for illness course in BD

18
Q
why do we are about preventing mood episodes in BD
A
because on average the risk of recurrence increases with # of previous episodes
also–> number of previous episodes is associated with increased duration and symptomatic severity of subsequent episodes
also–> number of episodes is associated with lower threshold for developing further episodes
also–> increased risk of dementia with more episodes
19
Q
what are the three broad clinical stages in the staging system for BD
A
- individuals at increased risk for developing BD due to family history as well as certain subsyndromal symptoms predictive of conversion to full BD
- patients with fewer episodes and optimal functioning in interepisodic periods
- patients with recurrent episodes as well as decline in functioning and cognition
*heterogeneity in BD has prevented clinical use of staging systems

how should you approach pharmacological treatment of acute mania when looking at the list of first and second line agents in CANMAT guidelines
they are listed HIERARCHICALLY
the implication is that those listed higher up in the table should be considered FIRST before moving on to the next on the list, unless other factors such as hx of previous non response or patient preference preclude such a strategy in a given patient
59
should monotherapy be tried before combination therapy?
not necessarily--> treating clinician makes the decision for mono or combo therapy

what do you do if a patient presents manic, but is currently on antidepressants
stop the antidepressants
if this is first presentation of mania, then should observe patient for a period of time after antidepressant discontinuation before starting antimanic therapy and obtain collateral
88
what % of patients presenting with acute mania will respond to monotherapy? in what time frame?
50% within 3-4 weeks
89
how does efficacy compare in acute mania treatment between the first line monotherapy agents
comparable efficacy
90
despite having level 1 evidence for efficacy, why are carmabazepine, olanzapine, ziprasidone and haloperidol downgraded to second line treatments for acute mania
due to safety/tolerability risks
91
why is combination therapy preferred to mood stabilizer monotherapy in acute mania
on average, about 20% more patients will respond to combo therapy
*though there are fewer trials, there is also evidence for combo therapy compared to atypical antipsychotic monotherapy for efficacy
92
which is associated with more adverse events, combo or monotherapy (in acute mania)

2. few episodes of prior illness
3. a mania-depression-euthymia course
and/or
4. those with family history of BD (especially if family hx of lithium response)
104

2. predominant irritable or dysphoric mood
3. comorbid substance use
and/or
4. those with hx head trauma
105
in what population must care be taken with divalproex
women of childbearing age--> teratogenic
106
which two antimanic agents may be particularly considered in those with a history of head trauma
divalproex
carbamazepine
107
does the presence of anxious distress during a manic episode give any prognostic information
yes-->
predictor of poor outcome
i.e greater severity of manic symptoms, longer time to remission, more reported side effects of medication
108
are there specific agents recommended to treat anxious distress is mania
not studies specifically examining this--> anxious distress tends to improve as the mood episode improves
post hoc analyses:
divalproex
quetiapine
olanzapine
may be helpful
109
in what % of cases do depressive symptoms CO-OCCUR alongside mania
10-30%
110
does the presence of mixed features give clues as to prognosis
indicative of more SEVERE and DISABLING course
HIGHER RATE OF SUICIDE
111
what pharmacologic treatment plan is preferred in patients presenting with BD with mixed features
preferential use of atypical APs + DIVALPROEX combo therapy
112
what % of manic episodes are characterized by the presence of psychosis
at least HALF
113
does it matter whether psychotic symptoms are mood congruent or incongruent in BD
if psychosis is mood incongruent seem t have more severe illness with poorer long term prognosis
114
is there any evidence of superiority of any first line antimanic monotherapy compared to any other when psychotic features are present?
no
also no evidnece that any particular combo therapy is better for psychotic features
**clinical experience suggests combo therapy of atypical AP + li/dvp more appropriate for manic patients with mood-incongruent psychotic features
115
what is the definition of rapid cycling BD
course of illness that includes four or more mood episodes in a year
116
what % of patients with bipolar I have rapid cycling BD
about 30%
117

hypothyroidism
antidepressant use
substance use
118
what should you try if your patient is rapid cycling
check thyroid function
stop antidepressants, stimulants or other psychotropic agents that may be contributing to cycling
consider withdrawing substances
