American Academy of Pediatrics Recommends Parents Avoid Spanking and Verbal Abuse

corporal punishment

The American Academy of Pediatrics (AAP) has issued a policy statement calling for an end to corporal punishment, including spanking. These forms of punishment are tied to negative outcomes in every developmental area.

Children spanked regularly at age 3 had increased aggression risk by age 5. They also had more negative behaviors and lower vocabulary scores at age 9. Abusive behavior raises stress hormones and is associated with mental health struggles.

Verbal abuse should also be avoided. Verbal abuse includes punishment that shames, humiliates, threatens, frightens, or ridicules a child. Use of time outs, removal of privileges, and other forms of quiet discipline are recommended alternatives.

Editor’s Note: In our research network, the Bipolar Collaborative Network, we found that verbal abuse by itself (without the physical or sexual abuse that often accompany it) is associated with an earlier age of onset of bipolar disorder and a more difficult course of illness.

Family focused therapy (FFT) and other forms of family therapy are highly recommended for children of a parent with bipolar illness. These children are at high risk for a variety of psychiatric diagnoses, and those already experiencing depression, cyclothymia (mood swings between high and low) or a diagnosis of bipolar disorder not otherwise specified (BP-NOS) are much improved with FFT compared to treatment as usual. FFT teaches family members to recognize symptoms of illness for what they are rather than interpreting them as deliberate hostility, increases family communication and problem solving, and leads to good long-term outcomes.

Recent Cannabis Use Linked to Greater Symptoms of Anxiety and Mood Disorders and Less Response to Treatment

November 8, 2018 · Posted in Risk Factors · Comment 

marijuanaIn a 2018 systematic literature review published in the Journal of Clinical Psychiatry, researcher George Mamman and colleagues reported that across 12 studies of people with anxiety and mood disorders, participants who had used cannabis in the previous six months had more symptoms than those who had used less cannabis or no cannabis during that period.

The 12 studies reviewed included a total of 11,959 participants. Four studies looked at post-traumatic stress disorder (PTSD), one at panic disorder, five at bipolar disorder, and 2 at depressive disorder. In addition to finding that recent cannabis use was associated with greater symptoms, the authors of the review also found that in 10 of the 12 studies, recent cannabis use was associated with less symptom improvement in response to treatment for bipolar disorder, depression, and PTSD; including both medication and psychotherapy.

In bipolar disorder, cannabis use was associated with greater symptom severity. Cannabis use for more than one year was linked to more recurrences of mania and shortened time to a recurrence. Compared to participants with no prior use of cannabis, those with a cannabis use disorder had more depressive symptoms, including sleep troubles and loss of interest in activities one had previously enjoyed.

In PTSD, any cannabis use at the beginning of the analysis period and sustained use of cannabis over time were both linked to greater symptom severity in the four months following the beginning of the analysis.

Mammen and colleagues cautioned that these results are limited based on the differences in measurements across the 12 studies, the inpatient populations under study, and the uncontrolled nature of the cannabis the participants accessed on their own time. However, the authors suggest that the findings may inform patients’ and doctors’ conversations about whether or not to use cannabis.

Early Intervention Works in Schizophrenia: Also Needed in Bipolar Disorder

For twenty years, evidence has shown that early intervention can ameliorate many of the adverse consequences of schizophrenia. In a 2018 article in the journal Annual Review of Clinical Psychiatry titled “Transforming the treatment of schizophrenia in the United States: The RAISE Initiative,” Lisa B. Dixon and colleagues described the importance of early intervention in schizophrenia. RAISE stands for Recovery After an Initial Schizophrenia Episode. Dixon and colleagues emphasize that shortening the time that a patient’s psychosis goes untreated, which averages 74 months, is critical to achieving good outcomes. In parallel to these consistent findings, researchers of bipolar disorder (including this editor Robert M. Post and colleagues) have found that an increased length of the interval before treatment is initiated in childhood-onset bipolar disorder is associated with a poor outcome in adulthood.

The RAISE program consists of four interventions: personalized psychopharmacology using a computerized decision support system, individual resilience therapy, family psychoeducation and therapy, and supportive employment and education. Compared with patients receiving standard treatments, patients who participated in the RAISE program showed greater improvements on almost all measures, including the Heinrichs-Carpenter Quality of Life Scale (main outcome), the Calgary Depression Scale for Schizophrenia, the Positive and Negative Syndrome Scale, treatment duration, and engagement in work and school. Moreover, the improvements were more substantial among patients with a shorter duration of untreated psychosis.

Editor’s Note: These findings are of great importance in their own right, but they also have great implications for treatment and research efforts in bipolar disorder. A 2013 randomized study by Lars Kessing and colleagues published in the British Journal of Psychiatry found that in bipolar patients hospitalized for a first or second episode of mania, two years of comprehensive treatment with psychotherapy, pharmacotherapy, and illness education that included mood monitoring and early symptom recognition was vastly superior to typical treatment, and this held true even six years later. In a 2014 article in the Journal of Clinical Psychiatry and a 2016 article in the journal Bipolar Disorders, researcher Jan Marie Kozicky and colleagues reported that in patients hospitalized with a first episode of mania, cognitive functioning and brain imaging abnormalities, respectively, returned to normal over the next year only if the patients experienced no further mood episodes. The message is clear: we must treat the first episode of mania comprehensively to avoid long-term deterioration, which occurs as a function of the number of episodes of mania or depression a patient experiences. However, this early multimodal approach is rarely taken in the US.

In schizophrenia, Dixon and colleagues noted that: “After the RAISE study reports were made available, Congress allocated additional funding to the community mental health …program, leading to growth in the number of…programs across the United States; they were expected to reach 48 states in 2018.”

The contrast between these efforts in schizophrenia and their virtual absence in bipolar disorder is incomprehensible and tragic. Studies in early schizophrenia have been funded for 25 years, while almost none have been funded in bipolar disorder, even in recent years. Community mental health programs for early schizophrenia will soon exist in 48 states; for patients with bipolar disorder there are no programs available in any state that I am aware of. The incidence of bipolar is about three times that of schizophrenia, and the long-term outcomes are often as devastating in bipolar disorder as in schizophrenia. There is a high incidence of drug abuse; social, educational and occupational deficits; and suicide in bipolar disorder. Early intervention with the many safe supplements, nutraceuticals, and well-tolerated drugs that are currently available to adult patients should be studied in young people with bipolar disorder, but such studies neither being funded nor conducted.

The reality is that childhood-onset bipolar disorder is poorly recognized and treated in the US, largely because of a paucity of treatment-related studies and knowledge about the best options for these young patients. If a reader of the BNN knows how to influence advocacy groups, leaders in the Substance Abuse Mental Health Services Administration (SAMHSA) and the National Institutes of Mental Health (NIMH), or influential politicians, it would be useful to take the initiative in bringing some of these deficits and disparities to their attention. Something must be done; ideas about how to do it are welcome. My own efforts to get funding for a childhood-onset bipolar research network in collaboration with such luminaries in the field as David Miklowitz (UCLA), Kiki D. Chang (Stanford University), Boris Birmaher (University of Pittsburg), Benjamin Goldstein (Stonybrook Research Institute), Eric Youngstrom (UNC, Chapel Hill), Soledad Romero (Hospital Clinic of Barcelona), and Josefina Castro Fornieles (University of Barcelona) have not been successful. We will keep trying, but the field needs to reach beyond the many investigators who are advocating for more treatment research to other people with more influence.

Antioxidant N-Acetylcysteine Improves Working Memory in Patients with Psychosis

June 20, 2018 · Posted in Potential Treatments · Comment 

NACIn a 2017 article in the journal Psychological Medicine, researcher Marta Rapado-Castro and colleagues reported that among 58 patients with bipolar disorder or schizophrenia and symptoms of psychosis, those who took two grams per day of the antioxidant n-acetylcysteine (NAC) showed improvements in working memory after six months compared to those who took placebo over the same study period.

Antipsychotic medications can typically reduce psychotic symptoms such as delusions or hallucinations, but cognitive symptoms such as problems with learning, memory, or information processing may remain. NAC, which is sold over-the-counter as a nutritional supplement, seemed to improve these symptoms.

The researchers suggest that larger studies of NAC are needed, particularly to determine whether giving NAC to patients during their first episode of psychosis could prevent cognitive decline from occurring at all during the course of their illness.

NAC has been found to have a range of benefits, including reducing substance abuse and interfering with habit-based behaviors such as compulsive hair-pulling, obsessive-compulsive disorder, and gambling.
Researcher Michael Berk, a co-author of the study, reported in the journal Biological Psychiatry in 2008 that NAC could also improve depressive symptoms in bipolar disorder and negative symptoms in schizophrenia.

Editor’s Note: Since cognitive deficits are common in both schizophrenia and bipolar disorder, using NAC in addition to antipsychotic medications could be a useful tool to address these types of symptoms.

Large Finnish Study Finds Lithium is Best at Preventing Re-Hospitalizations in Bipolar Disorder

A 2018 article in the journal JAMA Psychiatry reports that lithium and long-acting antipsychotic injections were most effective at preventing re-hospitalizations among people with bipolar disorder.

The study by Markku Lähteenvuo and colleagues included 18,018 Finnish patients with bipolar disorder. A national database contained information on any hospitalizations that occurred among the patients and what medications were dispersed to patients.

Among the participants, 54% (9,721 patients) were re-hospitalized at least once over a study period of 16 years. Medications associated with the smallest risk of re-hospitalization for psychiatric reasons were long-acting injections of risperidone, gabapentin, long-acting injections of perphenazine, and lithium carbonate.
When the researchers looked at hospitalizations for any cause (not just psychiatric illness), lithium was associated with the least risk of re-hospitalization, while benzodiazepines had the greatest risk, both for psychiatric re-hospitalization and re-hospitalization for any cause.

Long-acting injectable medications were associated with less risk of re-hospitalization compared to the identical medications delivered orally.

Lähteenvuo and colleagues concluded, “Lithium…should remain as the first line of treatment for bipolar disorder, after decades of underprescription.” They suggest that long-acting injectable medications may be a good alternative to prevent relapse in patients for whom lithium is unsuitable.

Editor’s Note: In addition to lithium’s ability to prevent depressions and manias, it also increases the volume of the hippocampus and protects against a diagnosis of dementia in old age. Lithium decreases the risk for suicide and also increases the length of telomeres, bits on the ends of DNA strands that protect them as they replicate, which are important to the maintenance of both physical and psychiatric health. When lithium is used cautiously to maintain doses below a given patient’s side effects threshold, it is very well tolerated by most individuals.

The Gold Standard in Bipolar Disorder Treatment

Lithium Treatment Lowers Suicide Rate in People with Bipolar Disorder

February 23, 2018 · Posted in Current Treatments · Comment 

lithium

A large study that made use of a Swedish health database has shown that lithium reduces suicide rates in bipolar disorder. The study by researcher Jie Song and colleagues was published in the American Journal of Psychiatry in 2017.

The study included eight years of data from 51,535 people with bipolar disorder. During that time, there were 10,648 suicide-related events recorded, such as suicide attempts or completed suicides. The researchers compared suicide rates when patients were taking lithium to rates when they were off the drug, and found that lithium reduced attempted or completed suicide by 14%. Song and colleagues also looked at suicide rates for people taking valproate, and found that these were no better than when patients were off valproate, implying that treatment alone is not enough to reduce the suicide rate and the benefit is specific to lithium use.

Song and colleagues estimate that 12% of the suicide-related events among the patients included in the study might have been avoided if the patients had taken lithium for the entire study period. While there are other clinical considerations to make when selecting an appropriate treatment for a given patient, the researchers suggest that lithium treatment should be considered for patients with bipolar disorder who have expressed suicidal intentions or who are otherwise at risk for suicide.

In Danish Study, Higher Trace Levels of Lithium in Drinking Water in Certain Regions Do Not Seem to Prevent Bipolar Disorder

Previous studies have found that trace levels of lithium that occur naturally in the drinking water of certain regions are associated with lower rates suicide. Preliminary studies have also shown that lithium in drinking water is associated with lower dementia rates. The trace levels seen in drinking water are many hundreds of times lower than clinical doses of lithium prescribed for bipolar disorder, but they vary greatly according to locality.

A new study by researcher Lars Kessing and colleagues investigated whether chronic exposure to lithium in drinking water might protect against bipolar disorder, but found no evidence that this is the case in Denmark.

In an article published in the journal Bipolar Disorders in 2017, Kessing and colleagues describe findings from their analysis of data on 14,820 patients with a diagnosis of mania or bipolar disorder and (for each participant with bipolar disorder) 10 other age- and gender-matched control participants totaling 140,311. The researchers were able to look longitudinally at the participants’ exposure to trace levels of lithium in drinking water based on their municipalities of residence.

The investigators hoped to find evidence that greater exposure to lithium was associated with lower rates of bipolar disorder. Kessing and colleagues concluded that trace lithium levels higher than those in Denmark might be needed to find such a result.

Editor’s Note: Clinical studies of lithium treatment for children at high risk for bipolar disorder could help clarify whether even conventional therapeutic levels of lithium could reduce or delay the appearance of bipolar disorder.

Adipokines May Be the Link Between Mood Disorders and Obesity

January 10, 2018 · Posted in Comorbidities, Resources · Comment 

weightResearchers David J. Bond and Lakshmi Yatham think they may have identified why bipolar disorder and obesity occur so often together. In North America, more than 60% of people with bipolar disorder are overweight or obese, and obesity rates are 60% higher in people with bipolar disorder than in people without bipolar disorder.

Bond and Yatham hypothesized that adipokines might be responsible for both bipolar disorder and obesity. Adipokines are cell signaling proteins that regulate both mood and appetite. Abnormal levels of adipokines in blood could cause both mood episodes and weight gain.

The researchers measured blood levels of five adipokines (leptin, adiponectin, resistin, adipsin, and lipocalin-2) in 53 young people with bipolar disorder. They found three interesting links between adipokines, mood, weight, and medications, which they reported in the Journal of Clinical Psychiatry in 2017.

The first finding was that low levels of leptin and adiponectin (adipokines with antidepressant properties) predicted a greater risk of depressive relapse over a 12-month period. The second finding was that high levels of leptin and adipsin predicted greater weight gain over a 12-month period. The third finding was that treatment with second-generation antipsychotics, which often leads to weight gain and other metabolic side effects, was associated with higher levels of resistin, an adipokine linked to type 2 diabetes.

The findings about leptin were particularly interesting, because leptin’s appetite-regulating effects change with a person’s weight. In the study, low leptin predicted depression, while high leptin predicted weight gain. In people of normal weight, low leptin predicts weight gain, while in overweight or obese people, high leptin predicts weight gain. Bond and Yatham suggest that leptin’s mood-regulating effects may be more consistent, with low leptin increasing depression risk regardless of weight.

These findings may help researchers find ways of treating mood episodes that do not encourage weight gain.

A Calculator of Risk for Bipolar Disorder in Youth

January 3, 2018 · Posted in Risk Factors · Comment 

Daniella Hafeman of the University of Pittsburgh described a risk calculator for predicting an individual’s risk for bipolar disorder, which is available at www.pediatricbipolar.pitt.edu. Possible factors included in the risk calculation include a parent’s early age of onset of bipolar disorder, mood shifts early in life, a child’s anxiety or depression symptoms, later affective mood shifts, and new onset of subthreshold mania.

Editor’s Note: A “poor man’s” assessment of risk can also be of help to a family or clinician. There are four components. The first is genetic. Having one parent with bipolar disorder is a potent risk factor, and can be further magnified if the other parent also has a mood disorder. If three or more first degree relatives or three or more generations of first degree relatives have a mood disorder, this further increases risk four- to six-fold.

Perinatal vulnerability is another factor. Beyond these genetic vulnerabilities, a history of maternal toxoplasmosis or a viral infection during pregnancy, or the infant being noticeably underweight at birth can contribute to bipolar risk.

Childhood adversity also contributes to vulnerability to early onset of bipolar illness. A history of psychosocial stress in the child’s early years, such as abuse or abandonment, can be an added risk factor.

Prodromal or preliminary symptoms are also a risk factor. The development of an anxiety or depressive disorder, a disruptive behavioral disorder, or a bipolar not-otherwise-specified diagnosis (BP-NOS, used to describe manic symptoms of short duration) further increases risk. In studies by David Axelson and Boris Birmaher, 50% of children with an initial diagnosis of BP-NOS developed full-blown bipolar I or II illness upon several years of followup if there was a family history of bipolar disorder. About one-third converted to full bipolar disorder if there was no family history of bipolar disorder.

Thus, if a child has three or all four types of risk factors, their risk would be substantial. In this case, one might consider attempts at prevention. This could include a good diet rich in omega-3 fatty acids, regular exercise, joining a school sports team, developing good sleep habits, playing a musical instrument, and engaging in something akin to family focused therapy. Family focused therapy emphasizes psychoeducation, good communication skills, and problem solving. Attending to and treating parents’ symptoms and building a support system for both parents and the child can also help.

While these endeavors are not a guarantee to prevent the onset of more severe illness, they are all health-promoting in general and have few downsides.
