relapse

The timeframe during which recovery and recurrence occur in people with a first episode of mania are somewhat variable. A meta-analysis by Andréanne Gignac and colleagues published in the Journal of Clinical Psychiatry in 2015 offers some new information. The meta-analysis included eight studies with a total of 734 participants in a first episode of mania. Syndromal recovery rates (when patients no longer met diagnostic criteria for bipolar disorder) were 77.4% at six months after first episode of mania and 84.2% at one year after. However, some symptoms lingered, and only 62.1% of patients reached a period of symptomatic recovery within one year.

Recurrence rates were 25.7% within six months, 41.0% within one year, and 59.7% by four years. Those who were younger at the time of the first episode were at higher risk for relapse within one year.

Editor’s Note: On the positive side, most recovered, but on the negative side, at one year, 60% remained symptomatic and 40% had a recurrence. What is not clear is how intensively patients were treated and monitored. The main message of this study is that a first episode of mania is not trivial and deservces concerted acute and long-term treatment. When expert multimodal treatment is given results are vastly more superior than treatment as usual (Kessing et al. British Journal of Psychiatry 2013).

Meta-Analysis Shows Effectiveness of Ketamine for Bipolar and Unipolar Depression

ketamine infusion

Ketamine, an anesthetic sometimes used intravenously in the treatment of depression, can bring about rapid onset of antidepressant effects. A new meta-analysis by researcher Michael Bloch and colleagues presented at a recent conference showed that ketamine’s maximum antidepressant effects occur within one day of administration, and its effects remain significant (compared to control conditions) one week following infusion. Ketamine’s effects were diminished in patients taking other medications. There was a trend for better response in patients with bipolar disorder than with unipolar disorder.

Bloch and colleagues analyzed eight earlier studies including a total of 180 participants. In each study, ketamine had been compared to a control condition, either an infusion of saline solution or of midazolam, which mimics ketamine’s sensory effects but does not have antidepressant effects. The researchers are calling for more meta-analyses of ketamine studies to determine which patients respond best to ketamine and how to sustain ketamine’s effects.

Editor’s Note: In another poster presented at the same conference, James Murrough reported that patients with slower processing speed responded best to ketamine. Other findings have shown that those with a history of alcohol abuse and a common genetic variant of brain-derived neurotrophic factor (BDNF), the val-66-val allele of proBDNF, are more likely to respond to ketamine.

Gene CACNA1C is Associated with Early-Onset Bipolar Disorder

DNA

Several genes have previously been implicated in bipolar illness. In a recent study, researchers at the Mayo Clinic, led by Paul Croarkin, compared variations in three genes (CACNA1C, ANK3, and ODZN) across 69 children aged 6–15 with mania, a 776-person control group from the Mayo Biobank database, and 732 adults with bipolar disorder (some with onset in childhood and adolescence and some with onset in adulthood, also from the Biobank). All participants were Caucasian, to minimize confounding by population stratification. The researchers found that the minor allele of rs10848632 in CACNA1C was associated with childhood onset of bipolar disorder. The haplotype (or sequence of nucleotides) T-G-G-T was the one associated with risk. Genetic risk scores were also associated with early onset of illness.

Editor’s Note: In research by Michael McCarthy and colleagues, CACNA1C has been linked to abnormal circadian rhythms in bipolar disorder and to responsiveness to lithium treatment. Together, these data suggest the importance of studying the calcium channel blocker nimodipine (which blocks calcium influx through CACNA1C) in childhood-onset bipolar disorder. A 1999 case report by Pablo A. Davanzo and colleagues described a teenager with ultra rapid cycling bipolar disorder (multiple mood switches/day) that did not respond to a host of conventional medications, who improved dramatically on nimodipine, reaching remission. This author (Robert M. Post) has also seen confirmed responsivity in adults with rapid cycling bipolar disorder (reported in the 2008 book Treatment of Bipolar Illness: A Casebook for Clinicians and Patients, by Post and Gabriele S. Leverich).

Omega-3 Fatty Acids Improve Mood and Limbic Hyperactivity in Youth with Bipolar Depression

omega-3 fatty acids

Children who have a parent with bipolar disorder are at risk for bipolar illness, but it may first present as depression. Treating these children with antidepressants has the risk of bringing on manic episodes. Researchers are looking for treatment options for youth at risk for bipolar disorder.

Robert McNamara and colleagues found that 12 weeks of omega-3 fatty acids (2,100 mg/day) significantly improved response rates in medication-free youth ages 9–20 years compared to placebo (64% versus 36%). Omega-3 fatty acids but not placebo also reduced the activation of limbic structures in the brain (the left parahippocampal gyrus) in response to emotional stimuli.

Editor’s Note: These data add to the literature on the positive effects of 1–2 grams of omega-3 fatty acids in depression. Given the safety of omega-3 fatty acids and the ambiguous effects of antidepressants in bipolar depression, omega-3 fatty acids would appear to a good alternative, especially since the FDA-approved atypical antipsychotics (quetiapine and lurasidone) are not approved for bipolar depression in people under age 18.

Brain Activity Differentiates Youth with Bipolar Disorder from Youth with Unipolar Depression

Both bipolar disorder and unipolar depression often begin in childhood or adolescence, but it can be difficult to distinguish the two using symptoms only. People with bipolar illness may go a decade without receiving a correct diagnosis. Researcher Jorge Almeida and colleagues recently performed a meta-analysis of previous studies to determine what neural activity is typical of children with bipolar disorder versus children with unipolar depression while processing images of facial emotion. They found that youth with bipolar disorder were more likely to show limbic hyperactivity and cortical hypoactivity during emotional face processing than youth with unipolar depression. Almeida and colleagues hope that this type of data may eventually be used to diagnose these disorders or to measure whether treatment has been successful.

ECT versus Drug Therapy for Bipolar Depression

March 3, 2015 · Posted in Current Treatments · Comment 

ECTElectroconvulsive therapy is often considered a primary treatment option for patients with severe bipolar disorder that has resisted pharmacological treatment. Researcher Helle K. Schoeyen and colleagues recently published the first randomized controlled trial comparing ECT (in this case right unilateral brief pulse ECT) with algorithm-based pharmacological treatment in 76 patients with treatment-resistant bipolar depression.

The response rate was significantly higher in the ECT group than in the patients who received drug treatment (73.9% versus 35.0%). However, the two treatment groups had similarly low remission rates (34.8% for ECT and 30.0% for pharmacological treatment).

The algorithm-based pharmacological treatment used in the study was based on a sequence of treatments endorsed by researchers Frederick K. Goodwin and Kay Redfield Jamison in their 2007 book Manic-Depressive Illness. A selected treatment was chosen for each participant based on his or her medical history. If the first treatment was ineffective or intolerable, the patient would be switched to the next treatment option. Antipsychotics, antidepressants, anxiety-reducing drugs, and hypnotics were some of the other treatments included in the algorithms.

Patients in the study had previously showed a lack of response to at least two different antidepressants and/or mood stabilizers with documented efficacy in bipolar disorder (lithium, lamotrigine, quetiapine, or olanzapine) in adequate doses for a period of 6 weeks (or until they quit because of side effects).

Editor’s Note: Even when ECT is effective, there is the issue of how to maintain that good response. We previously reported that in a 2013 study by Axel Nordenskjöld et al. in the Journal of ECT, intensive followup treatment with right unilateral brief pulse ECT combined with pharmacotherapy was more effective than pharmacology alone at preventing relapses. Patients who improved after an acute series of ECT (three times/week) then received weekly ECT for six weeks and every two weeks thereafter, totaling 29 ECT treatments in one year.

Other studies of more intermittent continuation ECT have not proved more effective than medication. Thus high intensity right unilateral brief pulse ECT is one option for extending the effects of successful ECT.

Employment Rights for People with Bipolar Disorder

“Society’s accumulated myths and fears about disability and disease are as handicapping as the…limitations that flow from actual impairment.”

—US Supreme Court

Attorney Katharine Gordon has provided some information on legal rights under the ADA.

When we think of the Americans with Disabilities Act (ADA), we might think of physical modifications to buildings, expensive lawyers, and complicated trials. But this law also gives people with bipolar ways to get fair treatment in the workplace. By learning a bit about your employment rights under this law, you can focus on excelling in your chosen career, rather than being sidetracked by ignorance, stereotypes, and stigma.

Here are a few things that you may not know about bipolar disorder and the ADA:

It is now clear that people with bipolar disorder are protected under the ADA in employment. Prior to 2008, there was often a battle of the experts to prove that a person with bipolar disorder had a severe enough impairment to be protected. This discouraged many from asking for their rights to be respected under this law in the first place. Unfortunately, companies would fire people for having bipolar disorder and then, in next breath, argue that bipolar wasn’t a real disability therefore it was legal to fire people for reasons related to their bipolar disorder.

This changed with the passage of the Americans with Disabilities Act Amendments Act of 2008, which made it easier to establish disability. The Equal Employment Opportunity Commission, the agency responsible for enforcing this law, has made it clear in official regulations that bipolar should generally be covered as a disability for the purposes of protection in employment: “It should easily be concluded that the following types of impairments will, at a minimum, substantially limit the major life activities indicated:…major depressive disorder, bipolar disorder, post-traumatic stress disorder, obsessive compulsive disorder, and schizophrenia substantially limit brain function.” 29 C.F.R. § 1630.2(j)(3)(ii), (iii).

Job applicants should never be asked whether they have bipolar disorder (or any other disability) until a conditional offer has been made. Read more

More Data on Memantine for Treatment-Resistant Depression

February 3, 2015 · Posted in Potential Treatments · Comment

In 2012 we reported on an open study by Athanasios Koukopoulos and colleagues that explored whether the NMDA glutamate receptor antagonist memantine (Namenda), which is used to treat dementia, could be helpful to people with treatment-resistant bipolar disorder. In an update of that study, the researchers, led by Giulia Serra, compared patients’ symptoms during three years of treatment as usual, followed by three years with memantine added to their stable medication regime (at doses of 20–30 mg/day). Patients improved progressively over the three years of taking memantine.

Improvements in symptoms included decreased time ill, decreased severity of symptoms, decreased duration of new episodes, and fewer episodes per year. Memantine was particularly helpful for those patients who had had rapid or continuous cycling. Side effects were minimal.

Given the success of this open study, randomized controlled trials are needed to explore this much-needed option for people with treatment-resistant bipolar disorder.

Keith O’Neil: A Football and Public Health Hero

January 21, 2015 · Posted in Resources · Comment 

Keith O'NeilKeith O’Neil is a former Super Bowl champion and the founder of the Forever Foundation, an organization whose mission is to educate the public about bipolar disorder and to de-stigmatize the illness. In September he spoke at the Brain and Behavior Research Foundation (formerly NARSAD) meeting in Washington, DC.

O’Neil’s life story holds many important lessons— not only about the difficulties of bipolar illness, but also about the hope of recovery. He described being six years old and experiencing high levels of anxiety and fear, and an inability to get to sleep. His mind raced and he was so irritable that he was nicknamed “The Bear.”

The anxiety and the racing thoughts continued, and O’Neil became increasingly depressed.  When he was 10 or 12 years old, he began to experience suicidal thoughts and searched his parents’ medicine cabinet for pills he could use to commit suicide. Anxiety and depression became more prominent even though he was an “A” student, one of the most popular kids at school, and an extraordinary athlete, and had a loving family and many friends. He began to use alcohol excessively, had conduct problems, was impulsive and was always in trouble.

O’Neil excelled in football in high school, started college at Northern Arizona University, and quickly became an All-American linebacker at Penn State. He was a first-round draft pick for the New York Giants. His teammates would nap between workouts for coach Bill Parcells, but instead, O’Neil would sit and cry over his inability to sleep. When he was later picked up by the Dallas Cowboys as a free agent, he was unable to sleep for five nights.

O’Neil moved on to the Indianapolis Colts. He did not sleep for four nights before his first game, and told coach Tony Dungy that he needed help, as he did not think he could play the next day. Dungy took him seriously and had him meet with the general manager, the team doctor, and the trainer. O’Neil felt extraordinarily relieved to be able to talk about his anxiety for the first time and took some clonazepam (Klonopin) for sleep and anxiety. Although he missed his first game, he became increasingly successful and the captain of the team that three years later would go on to win the Super Bowl.

O’Neil returned to the Giants for five seasons. While in New York, his wife miscarried, triggering O’Neil’s first major manic episode. He felt super human, spent excessive amounts of money (bought a Rolex watch and three diamond earrings), did not need sleep, and was generally out of control. In 2010, O’Neil was diagnosed with bipolar disorder by Steven Dubovsky, one of the pioneers in the development of calcium channel blockers for the treatment of bipolar disorder.

After his manic episode, O’Neil swung into a severe 18 month–long depression, which he described as “the depths of hell.” He gradually improved and started on a regimen that included medications, exercise, and relying on his family for comfort and support. He then moved to Phoenix, Arizona to start his foundation—the Forever Foundation.

The foundation provides information about the illness and promotes de-stigmatization. O’Neil visits high schools to teach students about bipolar illness and the importance of talking about anxiety and depression and getting help.

In the question and answer period following his talk, O’Neil discussed his own treatment. His early experiences with antidepressants were somewhat positive for his depression and anxiety, but may have been influential in his first manic episode. He said he is now well, and described his current medication regimen, which includes lithium, the mood stabilizing anticonvulsant oxcarbazepine (called Trileptal, which is structurally similar to carbamazepine or Tegretol), and the atypical antipsychotic aripiprazole (Abilify), which works extraordinarily well for him and which he called his savior. O’Neil occasionally uses Ambien (zolpidem) or Seroquel (quetiapine) for sleep.

O’Neil talked about the importance of confronting his own illness and adopting a positive attitude about getting treatment and doing everything he could to get well. He had a family history of mood disorders including depression in his paternal grandfather and bipolar disorder in an uncle.

O’Neil remembered that in his days as a professional football player, even though he was a standout player, he was so anxious that he would get confused about the playbook and have to rehearse it over and over in order to remember. He felt that he dealt with his racing mind and his anxiety in part by funneling it into “controlled recklessness” as a football player.

Keith O’Neil received a standing ovation from the gathering of scientists and approximately 150 supporters of the Brain and Behavior Research Foundation .

It is noteworthy that after Keith’s presentation, many of the scientific presenters speaking about the latest advances in the understanding and treatment of anxiety disorders in children, depression, and bipolar disorder directly referred to his life story and the important messages embedded in it.

Psychotherapy of Childhood Bipolar Disorder

January 16, 2015 · Posted in Current Treatments · Comment 

child psychologist working with a girl

At the 2014 meeting of the American Academy of Child and Adolescent Psychiatry, there was an excellent symposium on different psychotherapeutic approaches for children and adolescents with bipolar disorder and related illnesses.

Amy West of the university of Illinois at Chicago started off this symposium by describing the effectiveness of child-and family-focused cognitive-behavior therapy or what is sometimes called RAINBOW therapy. Rainbow stands for Routine, Affect regulation, I can do it, No negative thinking, Be a good friend and balance life stressors, Oh how can we solve problems, and Ways to find support.

West emphasized the importance of routine in sleep, diet, medications, and homework, and indicated that frequent soothing is necessary. Posted reminders are also helpful.

Affect regulation can be encouraged by promoting coping skills, particularly around identifying what triggers mood swings and rage attacks and creating plans for dealing with them.

I can do it” reminds parents and children to focus on strengths, successes, positive feedback, and the ability to call for help.

No negative thinking” encourages positive restructuring and reframing of negative perspectives. Part of this includes mindfulness training for children and parents, who are taught to focus on breathing and accepting thoughts and emotions.

Being a good friend focuses on listening, engaging friends, and enhancing communication.

Oh how can we solve problems” reminds families to have an attitude of problem solving.

Remembering ways to find support reminds parents to connect with relevant resources, and also coaches parents to be advocates for their children.

In a randomized study of 12 sessions of child and family focused cognitive behavior therapy, the children did much better than those receiving treatment as usual and showed greater improvement in mania and depression as well as overall functioning.

The second presentation was given by Mary Fristad of Ohio State University. She treated children with bipolar disorder not otherwise specified (BP-NOS) with psychotherapy and omega-3 fatty acids. Some research had suggested the efficacy of omega-3 fatty acids in childhood mood disorders and a much larger literature was positive in adult mood disorders. Given the safety of the manipulation, she felt it was worth trying in young children and those with BP-NOS who are rarely studied formally. She also cited a 2010 study by Amminger et al. in children who were at ultra high risk for schizophrenia. In that study, patients were randomized to 12 weeks of omega-3 fatty acids or placebo, and omega-3 fatty acids were associated with a very low conversion rate to full-blown psychosis, 4.9%, compared to 27.5% for those receiving placebo. Fristad’s psychotherapy also emphasized education, support, and skill building in order to enhance understanding of the illness and its treatment.  This would help ensure better compliance and better treatment outcome. Her formal treatment manual is available at www.moodychildtherapy.com.

Fristad randomized children with bipolar not otherwise specified, average age 10.2 +/- 0.2 years to either her psychotherapy plus omega-3 fatty acids or therapy plus placebo. Therapy plus omega-3 was much more effective on most outcome measures.

Editor’s Note: Given the safety of omega-3 fatty acids, even these limited data would appear to justify their use in children with BP-NOS in the context of psychotherapy and psychoeducation.

The third presenter was David Miklowitz of UCLA who discussed family focused therapy. This approach has proven effective in studies of both adults and adolescents with bipolar disorder, and as well for those with prodromal symptoms. Read more
