How does a hypomanic episode differ from a manic one?
- hypomanic also includes three of the characteristic symptoms but lasts at least four days, has no social or occupational impairment, does not require hospitalization, and has no psychotic features
- a manic episode is defined by having an impact on social or occupational functioning and may include hospitalization or psychotic features
What are the diagnostic criteria for MDD?
at least one major depressive episode and no history of manic or hypomanic episodes
What sleep disturbances are seen in those with MDD?
- most common is difficulty with sleep initiation and terminal insomnia
- may also have frequent awakenings
- they also tend to have REM shifted earlier in the night and less deep sleep
What neurotransmitter changes have been implicated in depression?
a decrease in serotonin, norepinephrine, and dopamine
What are the general guidelines and tools available for the treatment of MDD?
- predominately use SSRIs due to efficacy and tolerability followed by SNRIs and Wellbutrin
- TCAs and MAOIs may be necessary in atypical or refractory depression
- ECT has a role in patients unresponsive to pharmacotherapy, if patients are pregnant, or if rapid reduction of symptoms is necessary
- importantly, inclusion of psychotherapy enhances the efficacy of treatment regimens
What are the side effects of ECT?
retrograde and anterograde amnesia, headaches, muscle soreness, and nausea are most common
What is “atypical” MDD?

- normal bereavement may include illusions but should not include gross disorganization or suicidality
- normal grief is typically confined to two months with mild cognitive disorder lasting less than one year
What is the appropriate treatment for normal bereavement?
may use benzodiazepines to aid sleep but little else is required
What is rapid cycling mood disorder?
one defined by the occurrence of four or more mood episodes (manic, depressive, or mixed) in one year
What are the diagnostic criteria for bipolar I and II?
- the occurrence of one manic or mixed episode is sufficient to diagnose bipolar I
- bipolar II requires a history of one or more major depressive episodes and at least one hypomanic episode
What is the typical pharmacotherapy for bipolar disorder?
- mood stabilizers like lithium, the anticonvulsants carbamazepine or valproate, and atypical antipsychotics
- ECT also plays a role in treating refractory of life-threatening acute mania
What are the diagnostic criteria for dysthymic disorder?
> depressed mood for the majority of time most days for at least two years (1 year in children/adolescents) and without being symptom free for more than 2 months at a time > no major depressive episodes > at least two of the following: - poor concentration - feelings of hopelessness - poor appetite or overeating - sleep disturbance - low energy - low self-esteem > think "rule of 2's"
What is the preferred treatment for dysthymic disorder?
- cognitive therapy and insight-oriented psychotherapy are most effective
- antidepressants as adjuncts
What are the criteria for cyclothymic disorder?
- numerous periods with hypomanic symptoms and periods with depressive symptoms for at least two years
- the person must never have been symptom free for more than 2 months during this time
How is cyclothymic disorder treated?
with mood stabilizers like bipolar I and II
What is minor depressive disorder?
defined by 2-4 depressive symptoms that do not meet the full criteria for a depressive episode and which are interspersed with euthymic periods unlike dysthymic disorder
Describe seasonal affective disorder.
- a modifier to any mood disorder and not a true disorder in and of itself
- defined by at least two consecutive years of two major depressive episodes during the same season

for fall-onset seasonal affective disorder
What are the criteria for adjustment disorder?
- development of emotional or behavioral symptoms within 3 months following a stressful life event which resolve within 6 months of the stressor ending

- MDD
- Bipolar I
- Bipolar II
- dysthymic disorder
- cyclothymic disorder
- minor depressive disorder
- MDD: one major depressive episode and no mania
- Bipolar I: one manic episode
- Bipolar II: at least one hypomanic and one major depressive episode
- dysthymic disorder: a chronic, mild depression
- cyclothymic disorder: alternating periods of hypomania and mild-to-moderate depressive symptoms
What is the general treatment strategy for mood disorders?
- depressive disorders are treated with SSRIs, SNRIs, and wellbutrin followed by TCAs and MAOIs
- disorders with mania are treated with mood stabilizers like lithium, carbamazepine, valproate, and atypical antipsychotics
- ECT is used for acute, life-threatening situations and pregnancy when pharmacotherapy isn’t an option
