What is Bipolar Disorder?
• Everyone has ups and downs in mood.
• Bipolar disorder, also known as manic-depressive illness, features unusual shifts in:
• Mood
• Energy
• Activity levels
….in the way that affects carrying out day-to-day tasks.
• When many symptoms happen during the same week or two, it is usually an “episode” of illness
What is Bipolar Disorder?
• A highly recurrent, often disabling mood disorder
• The most lethal of the major psychiatric disorders
• The most grandiose of all psychiatric disorders—mimics all other disorders!
Bipolar disorder can be treated.
People with bipolar disorder can lead full and productive lives.
Risk Factors
• There is NO single cause of Bipolar Disorder.
• Many factors act together to increase the risk of illness:
Genetics: Having a parent or sibling with bipolar disorder increases the risk of bipolar disorder 4 - 6 times.
Changes in neurotransmitter and hormonal balance
Major life changes, particularly those disrupting sleep
How common is Bipolar Disorder?
Bipolar I affects of the population.
Bipolar I & II together affect of the population.
• Bipolar Disorder affects men and women equally.
• Bipolar Disorder usually starts in the teenage years (age 15-19).
What Defines DSM-IV Bipolar Disorder?
• The occurrence of one or more Manic Episodes, or Mixed Episodes
• Depressive episodes are frequent but not always necessary for diagnosis
• Main subtypes: I and II
Bipolar I versus Bipolar II
Bipolar I versus Bipolar II
• Bipolar I Disorder
– Requires a Manic Episode (or Mixed) episode
– May also have experienced a Major Depression
– Often includes psychotic symptoms
• Bipolar II Disorder
– Requires a Hypomanic Episode
– AND a Major Depression
– No psychotic symptoms or severe impairment in hypomania
– No mixed episodes
Phases of Bipolar Disorder
• Well state
• Depression
• Mania
• Mixed Episode
• Residual symptoms or ‘Subsyndromal’ State

BD Patients Are Symptomatic Almost Half Their Lives
Judd et al. Arch Gen Psychiatry 2002;59:530-537
N=146; 13 year Follow up
The Manic Episode
• A distinct period of abnormal and persistently elevated, expansive, or irritable mood (at least 1 week of daily symptoms for mania, and 4 days for hypomania)
• With abnormal mood, at least 3 of the following 7 symptoms exist:
Key Symptoms
• Increased self-esteem/grandiosity
• Decreased need for sleep
• Increased talking/pressured speech
• Flight of ideas/racing thoughts
• Distractibility
• Increase in activity or agitation
• Excessive pursuit of risky pleasurable activities
Manic Episode Continued...
• Not superimposed on other psychotic illness nor a mixed episode
• No organic factor (e.g. drugs, trauma)
• Marked impairment in social/occupational functioning
• No delusions/hallucinations for at least 2 weeks in the absence of mood symptoms
Hypomanic Episode
• ? The ideal human condition
• Same symptoms of mania, but very mild
• Never have psychotic symptoms; if present, call it a manic episode
• Minimum of 4 days
Hypomania Versus Mania
Hypomania
• Mild, less severe
• Little to mild dysfunction
• Little to mild lapses of judgment
• Commonly responds to outpatient management
• Sleep regulation and or benzos can sometimes terminate episode
Mania
• Severe
• Severe dysfunction
• Major lapses of judgment
• Psychotic symptoms
• Often requires inpatient treatment
• Need for acute mood stabilizer and or antipsychotic treatment
Major Depression
• Depressed mood or irritable mood most of the day, nearly every day
• Lasting at least 2 weeks
• Diminished interest or pleasure in daily activities
• Significant weight loss when not dieting or weight gain
• Insomnia or hypersomnia
Major Depression Continued…
• Psychomotor agitation or retardation nearly every day
• Fatigue or loss of energy
• Feelings of worthlessness or excessive or inappropriate guilt
• Diminished ability to think or concentrate or indecisiveness
• Recurrent thoughts of death
Tips to Diagnose Bipolar Disorder
• Family history
• Follow-up or Observation by the same treatment provider over a long time (months to years)
• Starting a diary of energy, drive, sleep and mood (from personal and family report)
• Identifying what “normal happiness” looks like
• Recognizing that extreme irritability may actually be a sign of mania
Missing the Diagnosis – Patient Survey
• Misdiagnosis occurred in 69%
• Most frequent misdiagnoses
– Depression (60%)
– Anxiety disorders (26%)
– Schizophrenia (18%)
– Borderline or antisocial personality disorder (17%)
– Alcohol/substance abuse (14%)
• 35% of patients waited 10 years or more for a correct diagnosis of Bipolar Disorder.
Data on file National DMDA
Differentiating Bipolar Disorder from other conditions
• Depending on the severity and frequency of symptoms, it is easy to misdiagnose:
– Acute depression diagnosed as unipolar depression
– Acute psychosis diagnosed as schizophrenia
– Mild symptoms diagnosed as ‘personality problems’
– Co-existing alcohol or substance misuse causes the bipolar disorder to be hidden
Possible Barriers to Diagnosis
• People don’t go to see a doctor if feeling too happy! (usually when depressed…)
• Often, people don’t remember hypomania or even mania
• Insufficient training in Bipolar Disorder for doctors
And that’s not all…
Bipolar disorder often co-exists with other illnesses:
• Psychiatric problems • Drug and alcohol problem
• Anxiety disorders
• Attention deficit hyperactivity disorder (ADHD)
• Other medical problems • Thyroid disease
• Migraine headaches
• Heart disease
• Diabetes
• Obesity
Key Goals in Treating Bipolar
• Educate not just the person but also family and friends about symptoms of BD
• Aim to improve functioning and symptoms
• Find a medication or combination of medication that works, and find a way to make easy to continue taking
• Identify new episodes early and treat
• Promote routine activity and sleep patterns
• Be aware of stressors and how to handle them
Probable Bipolar Triggers
• Sleep Deprivation
• Highly stressful events
• Certain substances including excessive alcohol, steroids, and some medications including antidepressants
Treating Any Phase of BD
• Supportive therapy and crisis management
• Acute phase—medicines are key to symptom
control
• Maintenance phase
– Minimize residual symptoms
– Maximize functioning
– Minimize medication side effects
– Provide support and psychotherapy as necessary
Pharmacotherapy
• Lithium
• Anticonvulsants
– Divalproex
– Carbamazepine
• Antidepressants
– Bupropion, SSRIs, venlafaxine, etc
• Antipsychotics
– Typical - haloperidol, perphenazine…
– Atypicals – olanzapine (Zyprexa), quetiapine (Seroquel), etc
• Others
– Benzodiazepines
– ECT www.psychguides.com
Traditional mood stabilizers

Examples of Medications
Psychotherapy
• Psychoeducation
• Cognitive behavioral therapy (CBT)
• Family-focused therapy
• Interpersonal and social rhythm therapy
• Peer-support and self-help strategies
Bipolar Disorder & The Brain
fMRI Scans During An Emotional Task Show Distinct BD Pattern Compared to Controls
Medial prefrontal cortex (red area) • less active
The hippocampus (blue/green region) • more active
Lagopoulos J et al, Neuroreport. 2007
Differences in brain function
Blue areas: the least active Red areas: the most active
Brain Chemistry
Different types of neurotransmitters release from neural ending and control the mood: • Dopamine • Serotonin • Norepinephrine
