“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

Abnormal Levels of Cytokines Found in Brains of Suicide Victims

February 4, 2015 · Posted in Neurochemistry · Comment

Cytokines are chemical messengers that send signals between immune cells and between the immune system and the central nervous system. Their levels in blood are considered a measure of inflammation, which has been implicated in depression and stress. A new study by Ghanshyam Pandey and colleagues reported increased levels of cytokines in the brains of people who committed suicide. In the prefrontal cortices of people who died by suicide, there were significantly elevated levels of the inflammatory cytokines IL-1 beta, IL-6 and TNF-alpha compared to the brains of normal controls. There were also lower levels of protein expression of the cytokine receptors IL-1R1, IL-1R2 and IL-1R antagonist (IL1RA) in the suicide brains compared to controls.

The researchers concluded that abnormalities in proinflammatory cytokines and their receptors are associated with the pathophysiology of depression and suicide. This research provides direct confirmation of the indirect measures of inflammation observed in the blood of depressed patients compared to controls.

More Data on Memantine for Treatment-Resistant Depression

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.

Anti-Inflammatory Treatment Prevents the Effects of Stress in Female Rats

Women are more likely than men to experience depression, and this difference begins in adolescence, when girls show more sensitivity to stress. Researchers are studying how animals react to stress in the hopes of learning what mediates these gender differences in mental illness.

At a recent scientific meeting, researcher Jodi Lukkes and colleagues presented a recent study of stress and inflammation in female rats. The rats were exposed to different types of stressors. Some were separated from their mothers for four hours a day during the first 20 days of their lives. Later, some rats were exposed to an acute stressor, witnessing another rat receiving shocks. All the rats were placed in a box in which they could escape a shock by jumping to the other end of the box, in order to measure their motivation. Because drugs that inhibit the inflammatory enzyme COX-2 had reversed the effects of maternal separation in earlier studies, the researchers also treated some rats with these anti-inflammatories.

The researchers found that anti-inflammatory treatment could prevent behavioral consequences of stress in adolescent female rats. Witnessing another rat being shocked brought about deficits in motivation (a depression-like behavior), but in rats that had received treatment with a COX-2 inhibitor, these deficits were reduced. The COX-2 treatment was only helpful to rats that had experienced an acute stressor in their lifetime, either maternal separation in infancy, or witnessing another rat receive the shocks. A history of stress was required for the anti-inflammatories to improve motivation.

Lukkes and colleagues hope that this research begins to clarify the relationship between stress, inflammation, and gender. This may eventually lead to new targets in the treatment of depression.

Transgenerational Transmission of Drug Exposure and Stress in Rodents

January 28, 2015 · Posted in Genetics · Comment

New data suggest that there can be transgenerational transmission of the effects of drug exposure and stress from a paternal rat to its offspring. The father mates with a female who was not exposed to drugs or stress and never has any contact with the offspring.  Consensus is now building that this transmission occurs via epigenetic alterations in sperm.

Epigenetic alterations are those that are mediated by chemical changes in the structure of DNA and of the histones around which DNA is wrapped. These changes do not alter the inherited gene sequences but only alter how easy it is for genes encoded in the DNA to be activated (transcribed) or suppressed (inhibited).

There are three common types of epigenetic modifications. One involves the attachment of a methyl or acetyl group to the N-terminals of histones. Methylation typically inhibits transcription while acetylation activates transcription. Histones can also be altered by the addition of other compounds. The second major type of epigenetic change is when the DNA itself is methylated. This usually results in inhibition of the transcription of genes in that area. The third epigenetic mechanism is when microRNA (miRNA) binds to active RNA and changes the degree to which proteins are synthesized.

At a recent scientific meeting, researchers described the various ways epigenetic changes can be passed on to future generations.

Researcher Chris Pierce reported that chronic cocaine administration increased brain-derived neurotrophic factor (BDNF) in the medial prefrontal cortex of rats. (BDNF is important for learning and memory.) The cocaine administration led to acetylation of the promoter for BDNF.

This exposure to cocaine in male rats who then fathered offspring led to two changes in the offspring, presumably conveyed by epigenetic changes to the fathers’ sperm. The first change was a decrease in cocaine reinforcement. The offspring took longer to acquire a cocaine self-administration habit. The second change was long-lasting learning deficits in the male offspring, specifically recognition of novel objects. The deficit was associated with a reduction in long-term potentiation in the offspring. Long-term potentiation is the strengthening of synapses that occurs through repeated patterns of activity. Surprisingly, the following generation also showed deficits in learning and memory, but did not show a loss of long-term potentiation.

Editor’s Note: These data indicate that alterations in sensitivity to cocaine (in this case slower acquisition of cocaine self-administration) can be transferred to a later generation, as can learning deficits in males. These data suggest that fathers’ experience of drugs can influence cocaine responsiveness and learning via epigenetic mechanisms likely mediated via epigenetic changes to the father’s sperm.

This research suggests the possibility that, in a human clinical situation, there would be three ways that a father’s drug abuse could affect his child’s DNA. First, there is the traditional genetic inheritance, where, for example, an increased risk for drug abuse is passed on to the child via the father’s genetic code. Next, drug abuse brings about epigenetic changes to the father’s sperm. (His genetic code remains the same, but acetyl groups attach to the BDNF promoter section of his DNA, changing how those proteins get produced.) Lastly, if the father’s drug abuse added stress to the family environment, this stress could have epigenetic effects on the child’s DNA.

Researcher Alison Rodgers described how epigenetic changes involving miRNA in paternal rats influence endocrine responsivity to stress in their offspring. Rodgers put rats under stress and observed a decrease in hormonal corticosterone response to stress. When a father rat was stressed, nine different miRNAs were altered in its sperm. To prove that this stress response could be passed on transgenerationally via miRNAs, the researchers took sperm from an unstressed father, loaded it with one or all nine miRNAs from the stressed animal, and artificially inseminated female rats. Rodgers found that the sperm containing all nine miRNAs, but not the sperm carrying one randomly selected miRNA, resulted in offspring with a blunted corticosterone response to stress.

Researcher Eric Nestler showed that when a rodent goes through 10 days of defeat stress (being defeated repeatedly by a larger animal), they begin to exhibit behaviors resembling those seen in depression. Social avoidance was the most robust change, and continued for the rest of the animal’s life. Animals did not have to be physically attacked by the bigger animal to show the depression-like effects of defeat stress. Just witnessing the repeated defeats of another rat was sufficient to produce the syndrome. Again, father rats that experienced defeat stress or witnessed it passed this susceptibility to defeat stress on to their offspring (with whom they never had any contact), likely by epigenetic changes to sperm.

Lithium Extends Anti-Depressant Effects of Ketamine in Mice

While it can sometimes take weeks for the effects of antidepressant treatments to appear, intravenous ketamine can produce antidepressant effects in as little as two hours. However, ketamine’s effects fade after three to five days. New animal research by Chi-Tso Chiu et al. explores whether adding lithium to ketamine treatment can produce more sustained antidepressant effects.

Mice who are restrained by being placed in a tube for several hours (chronic restraint stress) exhibit a behavioral and neurochemical profile that resembles human depression. When Chiu and colleagues pretreated these stressed mice with sub-therapeutic doses of lithium (600 mg/L) in their drinking water for several weeks, a sub-therapeutic dose of ketamine (2.5 mg/kg of body weight) was enough to produce robust antidepressant effects in the mice, while neither drug alone was effective at these doses.

The combination of ketamine and lithium also restored the density of spines on the dendrites of neurons in the medial prefrontal cortex. Post-treatment with lithium (1200 mg/L) for several weeks was also successful in extending the effects of a single (50 mg/kg) ketamine injection.

Both lithium and ketamine affect the intracellular signaling pathway mTOR. Ketamine activates the pathway, increasing levels of synaptic proteins and dendritic spine density. It also increases brain-derived neurotrophic factor (BDNF) and the BDNF receptor TrkB. BDNF is important for learning and memory.

When lithium was added to the treatment of the mice with ketamine, the mTOR and BNDF pathways were further activated. Lithium also inhibits the receptor GSK-3, supporting ketamine’s rapid-acting antidepressant effects.

Ketamine treatment can produce oxidative stress, in which toxic free radicals can endanger cells, and the addition of low doses of lithium also completely prevented this neurochemical side effect.

Chiu and colleagues hope that the findings of this study in mice can eventually be applied to research in humans in the hopes of finding a clinical option that would sustain the rapid-onset antidepressant effects of ketamine for the long term.

Combination of Lamotrigine and Quetiapine Superior to Quetiapine Alone

At a recent scientific meeting, researcher John Geddes and colleagues reported that compared to adding placebo to the treatment of bipolar depressed patients already receiving the atypical antipsychotic quetiapine, adding the mood stabilizing drug lamotrigine led to significant improvements in their illness. Lamotrigine was slowly titrated to doses of 200mg/day. (Slowly increasing dosage is important because a serious rash is a possible side effect of lamotrigine, occuring in about one in 5,000 individuals exposed.)

Researcher Charles Bowden found in 2000 that adding lamotrigine to valproate improved its effectiveness, as Marc van der Loos found in 2008 with lamotrigine and lithium. Thus it appears that adding lamotrigine to a mood stabilizer or to an atypical antipsychotic like quetiapine is a good second-line option in the treatment of bipolar depression. While lamotrigine is not FDA-approved for the acute treatment of depression, this approach is worthy of consideration, and could be of immediate clinical use. It provides an alternative to adding a unimodal antidepressant, which recent meta-analyses have indicated is not effective and which can increase switches into mania, cycle acceleration, or even treatment resistance in patients with 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.

Opiate and Alcohol Abuse

January 20, 2015 · Posted in Comorbidities · Comment

Deaths from opiate abuse are occurring in the US at about the same rate as automobile fatalities. At a recent talk, researcher Richard Ries discussed treatment of opiate addictions and the current epidemic of unintended opiate overdoses. Most opiates being abused come from other people’s leftover prescriptions. The best way to prevent opiate abuse is to throw out unused painkillers when they are no longer needed.

Many overdoses from opiates also involve alcohol and benzodiazepines, which can contribute to breathing difficulties.

There are several treatments available that can help patients abstain from using opiates. Treatment with opioid receptor antagonists (such as naltrexone (Rivia or long-acting Vivitrol, which is taken as an injection and lasts for 1 month), partial agonists (like buprenorphine), or full agonists (like methadone) results in, on average, an 80% decrease in the rate of hospitalization and an 80% reduction in crime, as well as a marked decrease in AIDS transmission. Without treatment, it is very difficult for people with opiate addictions to maintain abstinence, and relapse rates are extraordinarily high.

Treatment of Alcohol Abuse and Benzodiazepines

Ries also discussed data on treatment of alcohol abuse. He emphasizes that some aspects of withdrawal, such as sleep disturbance, can last a month or more after a parient’s last drink, putting the patient at high risk for relapse. Gabapentin, which is most often prescribed to prevent seizures, helps patients with this phase. Ries endorsed the combination of gabapentin and naltrexone as especially helpful. Carbamazepine is widely used in Europe for the treatment of alcohol abuse, and Ries also strongly endorsed the drug as another way of avoiding benzodiazepines. Several large placebo-controlled trials suggest that the anticonvulsant topiramate is also effective for long-term alcohol avoidance.

Editor’s Note: Another researcher, Mark Frye, found that women with bipolar disorder are more than seven times more likely than women in the general population to abuse alcohol, often in an attempt to self medicate their residual anxiety and depression. Excellent treatment of mood in bipolar disorder may have the double benefit of helping patients avoid alcohol abuse. The nutritional supplement n-acetylcysteine (NAC) also helps improve mood in bipolar disorder and has positive placebo-controlled data in heroin, cocaine, and alcohol avoidance.

Psychotherapy of Childhood Bipolar Disorder

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
