no
38
why is it important that comprehensive treatment for BD be initiated even after a first episode
in a subset of patient BD may be a NEUROPROGRESSIVE disease
--recurrences associated with reductions in brain grey and white matter volumes
--worsening cognitive impairment
--decrease in inter-episodic recovery and functioning
--higher rate and severity of relapse
--reduced rate of treatment response to both pharmacological and psychotherapeutic strategies
39

no--> only included in recommendations for acute treatment of bipolar depression HOWEVER if someone is stable on combo that includes antidepressant, withdrawing them may contribute to destabilization
48
how might dose be adjusted once the acute episode resolves and the patient enters maintenance treatment
may be necessary to lower the dose
patients often experience greater side effects once out of the acute episode
49
does combo treatment of AP + Li/DVP reduce risk of recurrence?
yes there is evidence for this --> continuing the AP for the first 6 months following response offers clear benefit in reducing risk of mood episode recurrence
reevaluate AP use after 6 months

lithium
b/c effective at preventing both manic and depressive episodes and appears to have anti suicidal effects
56
how heritable is lithium-responsiveness in BD
you are about twice as likely to respond to lithium if you have a lithium responding parents vs if you dont
patients who have a lithium responding relative have a 67% likelihood of also being lithium responsive
(vs 35% of those without a responsive relative)
("The neurons from people with BD were hyperexcitable and their activity was selectively modified by in vitro lithium in accordance with clinical response")

similar for both attempts and completed suicides
64
what % of those with BDII attempt suicide over the course of their illness? complete?

complete--> 1/25
65
why is it harder to generate recommendations for treatment of BDII
because there is a relative paucity of large, methodologically sound clinical trials in BDII

risperidone (open label)
*all generally suggested efficacy but had significant weaknesses
68
what does clinical practice suggest in terms of the management of acute hypomania
when its frequent, severe or impairing enough to require treatment--> consider mood stabilizers like lithium or divalproex and/or atypicals

as effective as both lithium monotherapy and lithium + sertraline therapy
76
how does the efficacy of venlafaxine compare to lithium in treatment of BDII depression
venlafaxine monotherapy was shown to be more effective than lithium
theres also maintenance data for venlafaxine in preventing relapses
*also--> buproprion was shown to be as effective as sertraline and venlafaxine

117
what is the relationship between DMDD and BD
The recent DSM‐5 diagnosis DMDD—which includes chronic irritability as a defining feature—lists BD as an exclusion criterion. However, the DMDD phenotype is evident in about 25% of adolescents with episodic BD, and is associated with factors such as greater family conflict and ADHD comorbidity.571 Classical BD and chronic irritability are therefore not mutually exclusive, the nonspecific nature of the latter notwithstanding.
