How is Bipolar Disorder Treated?
Source: Organization for Bipolar Affective disorder (OBAD) Effective treatment for bipolar disorder is often a combination of several componentsthat may include: Medication Therapy
Medication is key in the treatment of bipolar disorder. Approximately 75-80% of all
cases can be effectively treated with drug therapy. In the remaining 20%, drug therapy
can significantly reduce the impact of the disorder. Although some individuals with a
milder form of the disorder may choose not to use maintenance drug therapy, most
individuals do require medications to stabilize and maintain their wellness.
Psychotherapy
Individuals with bipolar disorder often experience considerable impairment in social and
occupational functioning. Other secondary problems associated with the disorder include
unemployment, legal and financial difficulties plus marital problems. Psychotherapy can
effectively help the individual overcome the consequences of the disorder.
Types of Therapy Include:
BehaviouralSupportive Integrated Family and Individual Therapy (IFIT) (This is a relatively new method for treating bipolar disorder. IFIT involves helping theindividual’s family understand the vulnerabilities that bipolar patients have, even tominor changes in their daily routines. Emphasis is placed on the patient keeping track oftheir regular daily routines. Family members are encouraged to assist the individual withmaintaining their regular social rhythms. Families are taught to watch for pendingepisodes and learn when and how to intervene.) Electro Convulsive Therapy
When medications fail to stabilize, electroconvulsive therapy (ECT) may be used as part
of an effective treatment program.
Lifestyle Modifications
Many individuals find that they have to make changes to their lifestyles that include
making healthy choices for living.
Education
Education is crucial for both the affected individuals and their families. It is important to
be proactive and to make informed, educated decisions regarding your mental health.
Education also helps to expedite the natural process of grieving within the family unit.
Self-Help
Joining a peer support or self-help group is often a necessary component to an effective
treatment program.
Medication Therapy: Mood Stabilizers
Lithium
Mood stabilizers, like Lithium and certain antiepileptics, such as Tegretol and Epival, and
Lamictal, can be used to treat bipolar disorder by altering the elements in the cell,
stabilizing nerve impulse transmission and chemical release. Neuronal excitability is
diminished by these medications by decreasing impulse transmission and returning body
movements to a more organized smooth state, relaxation, or sleep. The medications
decrease the spread of the neuronal activity, reorganizing impulse formation, chemical
release or response, synaptic response, or receiver cell response so messages are acted
upon appropriately.
Lithium was the first of the mood-stabilizing drugs. Lithium is a naturally occurring saltthat was discovered in 1817 by a Swedish chemistry student. Lithium was found inmineral rocks, natural brines, and mineral waters and in some plant, animal, and humantissues. In the mineral waters of European and American spas in the 19th and 20thcenturies, lithium was found to be an agent that promoted physical and mental health. Inthe late 1940’s, lithium chloride was used as a popular salt substitute for people on salt-free diets. In 1949, John E. Cade, an Australian psychiatrist, first discovered the mood-stabilizing effects of lithium. In 1957, Mogens Shou furthered Cade’s discovery andcampaigned for the use of lithium as a mood stabilizer, which led to the acceptance oflithium as a safe treatment for bipolar disorder.
Why lithium works remain unclear. Studies show that 70-80% of patients with maniarespond to lithium and do so in a relatively short time frame, 10 – 21 days. The additionof an antipsychotic, or secondary agent, is often necessary to curtail a full-blown manicepisode. Although beneficial, lithium can be potentially toxic and harmful. If bloodlevels are taken regularly and there is close supervision, toxicity is far less likely to occur.
Early signs of toxicity include:
In this event, one must call a doctor immediately and stop taking lithium.
Common side effects of lithium include:
Weight gainTrembling of the hands These should subside as your body adjusts to the medication. If these symptoms persistor become bothersome, inform your doctor.
experience excessive vomitingdevelop persistent fever become confusedhave slurred speech Anticonvulsants
(Tegretol/Epival/Neurontin/Lamictal)
Another classification of drugs that have been found to be helpful in the treatment of
mood disorders is anticonvulsants (Tegretol, Epival, Lamictal, and Neurontin). These
were first used to control seizure disorders. Anticonvulsants are effective in treating
refractory (difficult to treat) bipolar disorder, rapid cycling, and mixed states.
Anticonvulsants can be used in conjunction with lithium therapy to augment treatment.
Although they primarily reduce the symptoms of mania, they also decrease the effects ofdepression.
Discontinuation of an anticonvulsant involves careful and gradual reduction over severalweeks or longer. Abruptly discontinuing this medication may precipitate a seizure.
Regular blood tests are required to monitor the levels of the medication to ensure that atherapeutic level is maintained and to monitor possible toxicity.
Although very rare, Tegretol (Carbamazepine) has potentially serious side effects thatinclude: Massive hepatic cellular necrosis with total loss of intact liver tissue Common Side Effects Include:
Common Side Effects of Epival Include:
Rarely, Epival can interfere with blood clotting. Watch for unusual bruising and bleedingand report it to your physician promptly.
Epival also has the very rare side effect of liver damage, especially if taken with otheranticonvulsants, and bleeding disorders if there is a history of such disorders.
Most of the common side effects of anticonvulsants should subside as your body adjuststo the medication. Notify your doctor if seizures occur or if you develop vomiting,weakness, depression, skin rash, or yellowing of the eyes or skin while taking thismedication. When taking an anticonvulsant drug anyone using an oral contraceptivebirth control should take care. The combination of these two drugs can decrease theeffectiveness in reducing unwanted pregnancies. Anticonvulsant drugs should not be used during pregnancy unless clearly needed. Discuss the risks and benefits with yourdoctor. Small amounts of these drugs appear in breast milk. Consult with your doctorbefore breast-feeding. Inform your doctor if you have any diseases of the liver, kidney,brain, or blood prior to using an anticonvulsant. Be sure to mention if you are takingnon-prescription or prescription medication that may cause drowsiness such astranquilizers, sleeping pills, antihistamines, pain medication (narcotic-containing), orcough-and-cold products. Use of alcohol or other sedative type medications can lead toextreme drowsiness.
Side Effects of Lamictal:
As a new anticonvulsant-antiepileptic, psychiatrists began titrating (raising the dose) of
Lamictal too fast; which made some patients vulnerable to Stevens-Johnson syndrome, a
rare yet potentially fatal skin rash. One in 1000 patients contract Stevens-Johnson but the
results are seldom fatal if the drug is promptly discontinued. Lamictal has taken its place
as a valuable pharmaceutical tool that is now slowly titrated with far fewer incidence of
Stevens-Johnson. If you do experience rashes, particularly around mucous-producing
areas of your body, contact your doctor immediately.
Antidepressants
Mood stabilizers are more effective in the treatment of the symptoms of mania rather than
depression. Antidepressants may be prescribed to augment mood stabilizers for
symptoms of depression.
The main classification of antidepressants:
Noradrenergic and specific serotonergic antidepressants Selective Serotonin Noradrenergic Reuptake Inhibitors (SSNR’s Reuptake Inhibitors) (SSNRI’s) – Effexor, Serzone Wellbutrin is novel in that it works as a norepinephrine and dopamine modulator Selective Serotonin Reuptake Inhibitors (SSRI’s) Prozac, Paxil, Zoloft, Celexa, Tricyclics – Elavil, Norpramin, Tofranil, Pamelor, etc.
Monoamine Oxidase Inhibitors (MAOI’s) Parnate, Nardil, etc.
For many years doctors prescribed Tricyclics as the treatment of choice despite theirmany side effects such as dry mouth, lethargy, blurred vision, and constipation.
Tricyclics work by redirecting excitatory chemicals for use in the synapse to stimulate orexcite other neurons. For those individuals who did not respond favourably to tricyclicdrug therapy, doctors turned to the MAOI’s. MAOI’s work by blocking the enzymes thatbreak down chemicals, allowing further activity or excitement to occur in the synapse.
Dr. Nathane Kline first discovered the MAOI’s for their antidepressant properties, whenhe noticed an increase in mental alertness and a mild sense of elation in patients he wastreating for tuberculosis. Regardless of their effectiveness in the treatment of depression,MAOI’s require some caution because of possible and sometimes serious side effects on blood pressure. Certain foods can increase this risk, and so there are many dietaryrestrictions. The restrictions may decrease the desirability of this classification of drug.
If you are prescribed an MAOI, you will be given a list of foods, beverages, and othermedications to avoid. A secondary generation of antidepressants, called SSRI’s, weredeveloped to help those who did not respond well to MAOI’s. SSRI’s increase the levelof serotonin in the brain. Prozac, Paxil, and Zoloft, are now considered standard therapydue to their high level of tolerability and safety. SSRI’s are also used in the treatment ofpanic, obsessive-compulsive, and eating disorders.
Common side effects of antidepressants include:
Difficulty urinatingConstipation Dry eyes and mouthFeeling dizzy or light-headed Antidepressants are often prescribed for six months to a year to ensure against a relapse.
Discontinuation involves careful and gradual reduction over several weeks or longer.
Abruptly stopping medication can lead to withdrawal symptoms such as intenserestlessness and anxiety. For individuals with bipolar disorder, antidepressants canprecipitate a manic episode if used without a mood stabilizer.
Anti-psychotics
Recently, “atypical” anti-psychotics such as Risperdal, Seroquel, or Zyprexa may be
prescribed as a supplement to a mood stabilizer to control hallucinations and delusions in
severe mania or psychotic depression. Antipsychotic medications work by blocking the
flow of the neurotransmitter dopamine and some by blocking dopamine and serotonin.
By changing the flow of these neurotransmitters, medications can reverse some of the
symptoms of the disorder.
Antipsychotics can have severe side effects, especially in higher does or after long-termuse. Side effects include influences on the nervous system that, in turn, results intremors, rigidity, or restlessness.
Other common side effects are dry mouth, weight gain, drowsiness, blurred or doublevision, or sensitivity to light.
If any severe side effects do occur, contact your doctor. It is important not to stop takingyour medication without your doctor’s knowledge.
Atypical anti-psychotics
Anti-psychotic medication has been a treatment for bipolar disorder for many years.
These medications are often used in the acute phase of the manic state (to rapidly settle
the patient or induce sleep). It is also employed against major depression with psychotic
symptoms. The occasional patient would require this class of medication on a long-term
basis to remain well. Since the introduction of newer ‘meds’ with reduced neurological
side effects and enhanced effects, these medications are being used more frequently and
for longer durations.
The major reason that these older medications were avoided for longer duration treatmentwas because of the enhanced potential for chronic and occasionally irreversibleneurological side effects. The particular chronic side effect was Tardive (late or slowdeveloping), Dyskinesia (abnormal involuntary movements such as tongue writhing,increased mouth and rarely limb movements). Other side effects include dry mouth,hypotension (low blood sugar with dizziness), blurred vision, constipation, and sedation.
Acute neurological side effects like dystonia (tight muscles in jaw or face), tremors,ackathisia (unpleasant sensation of crawling flesh relieved by constant movement plusdifficulty sleeping.
All of these aforementioned side effects are reasons psychiatrists preferred to usebenzodiazepines (Valium, Ativan, Rivotril, etc.) or the other older antipsychotics for theshort term. Examples of older antipsychotics include Haldol, Chlorpromazine, Mallaril,Stelazine, Nozinan, and Trilafon.
The new, or ‘atypical’ antipsychotic meds boast considerably less potential forneurological side effects, with considerably increased potential for beneficial gains thanthe older anti-psychotics. Enhanced gains include improved sleep, better cognition(improved memory, concentration, judgement, and reduced impulsivity), plus betterstability in terms of mood, energy, and general wellbeing.
These findings were originally suggested by a study done years ago in which a treatment-resistant bipolar patient responded favourably to Clozaril. The patient benefit was sosignificant that the author suggested that bipolar patients actually benefit more thanschizophrenics – which the drug was intended for.
Next on the scene was Risperdal. This medication has been shown to be effective forsymptoms of psychosis, provide an antidepressant effect, anti-manic effect, better sleep inboth manic and depressive states, plus general mood stabilization. The side effect profileis significantly improved over older anti-psychotics but at elevated doses of 4 or 6 mg’s,acute neurological side effects (dystonia, tremors, and ackathisia can occur). Weight gainis less than with Clozaril and Zyprexa, yet still occurs. At higher doses, Prolactin levelscan rise, producing lactation (breast milk production) and menstrual difficulties. Zyprexaemerged as the only antipsychotic medication with approval from the Food and DrugAdministration in the United States to be used and advertised as a treatment for BipolarDisorder. To achieve this approval, a medication must be subject to numerous studies to prove it is effective and safe in treating this illness. That is not to suggest that amedication without approval is not safe or effective only that, whatever the reason, thepharmaceutical company that owns the medication has not gone through these rigorousstudies to get this approval. Zyprexa is effective to anti-manic effect, anti-depressanteffect, anti-psychotic effect, sleep effect, and mood-stabilizing effect. From the sideeffect perspective, Zyprexa can produce significant appetite increase with weight gain inat least 40% of patients (in particular, thin people) and hypotension (low blood pressure)in the elderly.
Medication change and adjustment decisions should always be discussed with yourdoctor. The doctor should be receptive to your input. Be frank and assertive whendiscussing your side effects. These decisions always have the potential for enhancedbenefit or fewer side effects, but at the same time, carry the risk of reduced benefit andmore side effects. This is because individual differences in people are just as importantas the scientific basis and the doctor’s experience in making these decisions.
Anti-anxiety agents
Anti-anxiety agents such as benzodiazepines (Rivotril, etc.) have been used as an adjunct
to mood stabilizers to create calming effects or sedation. They decrease the transmission
of the nerve signals by blocking the chemicals, especially dopamine, at targeted receptor
sites. They offer relatively quick relief from often very disturbing and agonizing
symptoms while the individual waits for the other medications to take effect and control
other manic or depressive symptoms.
Common side effects include:
Driving or operating machinery can be dangerous because of the drowsiness and blurredvision. As anti-anxiety agents are habit forming and have potentially serious side effects,both patient and doctor must carefully weigh the benefits and risks of using these drugs.
Treatment Resistance: When Drug Therapy Fails
Most individuals will experience an improved quality of life after they begin drugtherapy. However, just like the disorder is experienced differently, the treatment ishighly individual. No single treatment will be effective for all people at all times. Someindividuals require additional or different medications. It is estimated that 20 percent oftreated individuals will not respond to the first treatment tried. Managing the disorder isa lifelong process and requires continuous monitoring. For any treatment to work, youmust be actively involved.
What is treatment resistance?
Treatment resistance is a lack of satisfactory response after a period of time, often after
several different options have been tried. There are many reasons why some treatments
fail or appear to fail.
Side effects
Most medications used to treat mood disorders have side effects. Individual reaction and
tolerance to side effects differs from one individual to another. Some side effects will
diminish after several weeks of treatment. Some side effects may become intolerable,
making the treatment worse than the condition. Sometimes a reduction in the dosage can
improve the unwanted side effects.
The decision to alter medication must be made in partnership with your mental healthprofessional.
Insufficient dose
Due to the physiological differences among individuals, dosages required to reach
therapeutic levels in one may be different in another. Inadequate levels of the drug may
contribute to a feeling that the medication is not working. Increasing the dosage with
your doctor’s approval might rectify this.
Inadequate time
During the initial stages of treatment, the treatment may appear to fail. The reality may
be that the body has not attained ‘therapeutic levels’ of the medication. Medications can
sometimes take at least a month of continued use to reach appropriate levels in the body.
Non-compliance – the most common reason for treatment failure – is due to individuals
not taking their medication as prescribed. Medication non-compliance can be a
consequence of the disorder since confusion, distractibility, and memory impairment are
common in bipolar disorder. Sometimes, if there is a breakthrough manic episode, the
individual will feel a false sense of security believing he/she is cured. This is not the case.
If a breakthrough depression occurs, hopelessness may be experienced, leaving the
individual feeling ‘what does it matter’. Their thinking may be impaired and they need to
be encouraged to continue with their medication and to contact their doctor. Some
people find that using a dosette (a pill scheduler) helps them to remember to take their
medication.
Adverse drug interactions
Individuals who are taking medications for other conditions may experience an adverse
drug interaction when mixed with a psychiatric drug. This can lead to an intolerable side
effect or a decrease in the amounts of mood stabilizing drugs in the bloodstream,
preventing them from reaching therapeutic levels. Always inform a doctor or dentist of
your current medications.
Non-response
A small number of individuals may not respond to a particular medication. It is
important not to give up hope. There are a multitude of alternative treatment strategies.
If one doesn’t work for you, try another.
ElectroConvulsive therapy (ECT)
Electro Convulsive Therapy (ECT) is a treatment option for individuals who are notresponding adequately to drug therapy in the treatment of bipolar disorder and otherpsychiatric disorders. ECT is the brief application of electric stimulus to the brain thatresults in a generalized seizure. In the 1940’s and 1950’s, there were many instances ofabuse where ECT was used in high doses and for long periods. This has contributed tothe perception of ECT as an abusive instrument of behavioural control.
Current studies have shown that ECT and lithium are equally effective for acute mania.
It also appears that if ECT is used for an acute episode of mania, followed by lithiummaintenance, there is a decreased risk of relapse, as opposed to treatment with lithiumalone.
In studies of ECT as a treatment for depression, ECT clearly immediately reduced thesymptoms of depression for the short term, where antidepressant therapy failed.
However, relapse rates in the year following ECT are likely to be high, unlessmaintenance antidepressants are used. ECT has also been shown to be a highly effectivetreatment for delusional depression. Its effectiveness is superior to anti-depressant oranti-psychotics administered alone. It is equally effective as taking a combination of ananti-depressant and an anti-psychotic.
How is ECT performed?
The procedure is generally performed in the recovery room of a hospital or in a
specialized room. An intravenous tube is inserted to provide any medication that may be
required during the procedure. Your vital signs are taken initially and throughout the
procedure. You will be given a general anaesthetic. A paralyzing agent called
succinylcholine is administered to prevent a generalized seizure. Electrodes are then
applied to your head with conducting jelly and a brief shock is administered.
What are the risks of ECT?
ECT should be administered to individuals where it is clearly indicated. Risks and
benefits must be weighed carefully against the risks of other treatment options. Over the
years, safer methods of administration have been developed, including short-acting
anaesthetics, use of muscle relaxants, and adequate oxygenation. This has decreased the
mortality rate associated with ECT to 4 deaths per 100,000. This means that there is a
marginally greater increase in risk that that of any procedure requiring anaesthetics. The
seizure experienced may cause various complications such as vertebral compression
fractures.
Immediately after regaining consciousness from the treatment, the individual willexperience confusion, transient memory loss, and headaches. The time it takes to fullyrecover consciousness varies from one individual to another. The loss of short-termmemory can be troublesome and can often persist after the termination of a normal courseof ECT. Severity of the memory loss is often attributed to the number of treatments, typeof electrode placements, and nature of the electric stimulus. Some individuals reportdifficulties remembering events, on average, 6 months prior to receiving ECT and for 2months after ECT. The perception of the memory loss varies widely from one individualto another. The ability to learn and retain new information is also adversely affected for atime following administration of ECT for several weeks following its termination.
Normal functioning typically returns after a period of time.
