Comorbidity

The simultaneous presence of two or more chronic diseases or conditions in a patient.

Mood Disorder Etiology

Biological Theories - major focus for understanding the cause of depression and bipolar disorder. Some research shows link between physiology, genetics, and mood disorders.

Flight of Ideas

A confused state in which thoughts and speech go in all directions with no unifying concept

Rapid Cycling

A pattern of bipolar disorder involving at least four manic or depressive episodes per year

Hyperprexia

Extreme body temp increase of over 106 F

Electroconvulsive therapy (ECT)

A treatment that involves inducing a mild seizure by delivering an electrical shock to the brain

Bipolar II Disorder

The patient has one or more hypomanic episodes alternating with major depressive disorder.

Epidemiology

-19.3% of general population -depression occurs in 21.3% of women and 12.7% of men -bipolar onset: Mid- to late 20s -depression onset: Mid 30s -depression frequency greater in Caucasians, Hispanics, and lower socioeconomic groups -bipolar frequency greater in higher socioeconomic groups

Carbamazepine (Tegretol), Valporic Acid (Depakene), Divalproex Sodium (Depakote)

-2nd generation anticonvulsant -require a therapeutic serum level of 50-100; greater than 100 is toxic -toxic reactions include blood dycrasias (disorder of the cellular elements of the blood) -do not eat grapefruit or drink grapefruit juice

Gabapentin (Neurontin)

-3rd generation anticonvulsant -found to be ineffective for bipolar -abrupt withdrawal can cause seizures

Medical Conditions and Mood Disorders

-A medical patient develops a mood disorder as a stress response to a serious medical condition. -A medical patient develops a mood disorder as a physiologic response to either medical pathology or medication. -A psychiatric patient with a persistent mood disorder develops common medical disorders. -A psychiatric patient with a persistent mood disorder has an exacerbation of symptoms as a result of medical pathology or treatment. -Health care providers identify previously unrecognized relationships between mood and medical disorders.

Early-Onset Bipolar Disorder (EOBD)

-Once thought to emerge around early adulthood, but has recently been made as early as 5 years old. -symptoms overlap other childhood psychiatric disorders -difficult to distinguish from ADHD with the exception of EOBD having cyclic patterns not evident in ADHD or other disorders

Adjustment Disorders

-Problematic responses to life events -Affecting otherwise mentally healthy people -Transient episodes of dysfunction in response to specific stressors -Acute duration: 6 months or less -Chronic duration: 6 months or more

Diagnosing Depression in Older Adults

-Requires three (instead of five) symptoms from the DSM-IV list -the list is expanded to include irritability, social isolation or withdrawal, assessing for decreased positive affect rather than loss of interest, no longer requiring symptoms to occur nearly every day but rather determining that they represent a change from previous behavior.

Social Symptoms of Dysthymic Disorder

-Social withdrawal -patient's mood and negativity make people not want to be around them

Atypical Depression

-mood reactivity -loss of ability to react to positive stimuli -significant weight gain or increase in appetite -hypersomnia -leaden paralysis or heavy feeling in arms and legs -long standing pattern of being sensitive to interpersonal rejection -associated with suicide more often than other depression types

While you're taking an MAOI, your doctor may recommend eating only fresh foods — not leftovers or foods past their freshness dates.

Seasonal Affective Disorder (SAD)

-a seasonal pattern occurs when a regular temporal relationship between onset and remission of episode of major depression (unipolar or bipolar) at particular time of year -must be evident for 2 consecutive years with no intervening nonseasonal episodes -seasonal episodes of altered mood must outnumber any nonseasonal episodes over a lifetime -mostly develop during October or November to March or April; some during summer -atypical features associated with SAD -increased light triggers manic or hypomanic episodes in bipolar II disorders

Melancholic Depression

-anhedonia and a lack of reactivity to any pleasurable stimuli -a distinct quality of mood in which the patient perceives the depression as different from the feeling after the death of a loved one -worse in the morning -sleep disturbances of waking at least 2 hours before normal -marked psychomotor retardation or agitation -Weight loss or loss of appetite -excessive guilt

Norepinephrine Dopamine Re-Uptake Inhibitors (NDRIs)

-bupropion (Wellbutrin) -2nd Line antidepressant that is resistant to SSRI or SSRIs -lowers seizure threshold; don't take with seizure disorders or eating disorders

Children and Adolescents

-can begin in early childhood and adolescence -less is known about the diagnosis and treatment than that of adults -Mood disorders at this age are significant: 1) they generate extraordinary pain and distress due to them not being prepared to understand or deal with the emotions and behaviors 2) initiate major difficulties during this period of time that is essential to psychosocial development 3) they produce tremendous stress and concern for the entire family unit 4) they affect the educational experience 5) they influence biologic processes and brain functioning to create changes that will have lifelong effects -may occur as early as infancy

Psychotherapeutic Intervention

Cognitive Symptoms of Major Depressive Episode

-diminished ability to think, concentrate, or make decisions -recurrent thoughts of death -excessive focus on self-worthlessness and guilt -negative thinking -sometimes delusional -fixed beliefs that cannot be changed by logic -Delusions focus on persecution, punishment, nihilism, or somatic concerns

Alternative and Complementary Therapy

-family intervention -group intervention -psychotherapeutic intervention -self-management intervention

Postpartum Mood Disorder

-includes manic or depression symptoms after birth of child -most common in childbirths with complications -15-20% of new mothers affected -usually within 3 months of the birth -severe forms include hearing voices and experiencing delusions

Social Symptoms

-increased sociability and sexuality -intrusive, interruptive, and disruptive during conversations or activities -fluctuations between euphoria and anger

Behavioral Symptoms

-increased talkativeness -decreased need for sleep -increased goal-directed behavior or agitation -excessive involvement in activities thought to be pleasurable, risky, or even dangerous

Nonadrenergic/Specific Serotonergic Antidepressants (NSSAs)

-mirtazapine (Remeron) -higer risk of seizures than tricyclic antidepressants -use with MAOIs may increase the risk of hyper pyretic crisis, hypertensive episodes, and severe seizures -self-harm and suicide more likely when younger than 18 years old

Prognosis for Dysthymia

-often continues for years before individuals seek assistance -most are unaware of chronic low-level symptoms are treatable -many with dysthymia go on to develop major depression -with proper treatment, the prognosis for maintaining functioning with mood disorders is favorable but most people don't seek treatment, comply with treatment regimen, lack proper diagnosis

Older Adults

-older adults less likely to report depressed mood -tend to describe somatic symptoms such as apathy, fatigue, difficulty sleeping, and loss of interest ion usual activities -Made worse by loss of SO and friends at this time of life -often have no support system -social and generational differences: sometimes depression is seen as a normal part of aging or some not accepting psychiatric treatment -depression could be a an early sign of dementia

Depressive Disorders not Otherwise Specified

-premenstrual dysphoric disorder -minor depressive disorder -recurrent brief depressive disorder -postpsychotic depression of schizophrenia

Lithium

-require therapeutic drug monitoring to prevent toxicity -0.6 to 1.2 is therapeutic -greater than 1.5 is toxic -1.5 to 2.0 results in vomiting, diarrhea, drowsiness, confusion, lack of coordination, coarse hand tremor, muscle twitching, and t-wave depression -Acute toxicity may have seizures, oliguria, circulatory failure, coma, and death -may not work or side effects are intolerable for half that have bipolar -monitor sodium intake, changes can alter lithium excretion

-trazadone (Desyrel), nefazodone (Serzone) -may increase risk for hypertensive crisis when taken with MAOIs -trazadone is used for insomnia; can contribute to dysrhythmias

Prognosis for Major Depression

-usually a lifetime disorder -most people who experience depression have recurrences -long term outcomes tend to be less than positive -less than a third of people who experience depression seek treatment -with proper treatment, the prognosis for maintaining functioning with mood disorders is favorable but most people don't seek treatment, comply with treatment regimen, lack proper diagnosis

Prognosis for Bipolar Disorder

-usually a lifetime disorder -perceived as recurrent with periods of depression and mania interspersed with periods of euthymia -some experience rapid cycling -high rate of recurrence and relapse -factors that contribute to relapse: number of and recovery from previous episodes, a family history, functional incapacity with episodes, past psychotic episodes, and past suicide attempts -with proper treatment, the prognosis for maintaining functioning with mood disorders is favorable but most people don't seek treatment, comply with treatment regimen, lack proper diagnosis

Social Symptoms of Major Depressive Episode

-withdraw from family and social interactions -problems at work as a result of the inability to organize, initiate or complete work -financial problems
