Two different subtypes of early onset unspecified bipolar disorder (USBD)
The first subtype is classical BP NOS (Not Otherwise Specified) having all the characteristics of full-blown bipolar disorder except for only having brief durations of mania and responding to conventional treatment. The second is what is now called Temperature and Sleep Dysregulation Disorder (TSDD) and was formerly described by D. Papolos as the Fear of Harm (FOH) syndrome, and requires a different treatment approach.
Clinicians should be alert to unique symptoms in children who might have TSDD as such a diagnosis would lead to a unconventional treatment paradigm. We emphasize the importance of specifically asking parents about evidence of over heating (red face and red ears) and high tolerance for cold (going outside markedly under-dressed) and the presence of fear of sleep and horrific nightmares, as these may lead one to consider the diagnosis of TSDD.
If these two novel aspects (temperature and sleep dysregulation) occur in the presentation of a highly fearful and behaviorally dysregulated child with bipolar-like symptoms, these may lead to the consideration of an unconventional treatment paradigm. It utilizes 1) high dose lithium; 2) clonidine and other practical approaches to achieve cooling and relieve over heating; and 3) ascending doses of intranasal ketamine (as described by Papolos et al 2013; 2018). This may be of considerable clinical importance as a large group of children with this unique presentation respond very poorly to conventional treatments for bipolar disorder and remain highly impaired and dysfunction throughout their childhood and adolescence.
If these children instead are treated with: lithium (to achieve blood levels of 1.0 meq/L or higher); clonidine (0.1- 0.3mg IR and 0.1mg ER at noon and HS) and other practical ways to achieve cooling; followed by ascending intranasal doses of ketamine (starting at 20mg and increasing toward 80-260mg/day, repeated every 2-3 days), marked improvement can be achieved. This occurs in conjunction with ketamine’s positive effects on fear and aggressive behaviors in association with its ability to reduce core body temperature.
We highlight this potential alternative treatment approach as long term positive effects have been achieved with it in open case series (Papolos et al 2013; 2018 ). The efficacy of this treatment approach has not been validated in controlled clinical trials, but we believe wider recognition of the two subtypes of USBD– BPNOS and TSDD,– will lead to more systematic research on treatment. Actively looking for the unique features of TSDD and pursuing its unconventional treatment may lead to long term positive effects in a child previously viewed as having an intractable psychiatric illness.
Antihypertensives That Stimulate vs Inhibit Type 2 and 4 Angiotensin II Receptors Decrease Dementia
Marcum et al in JAMA New Open (2023) found that in “57,773 Medicare beneficiaries, initiation of antihypertensive medications that stimulate vs inhibit type 2 and 4 angiotensin II receptors was associated with a statistically significant 16% lower risk of incident dementia, over a median of 6.9 years of follow-up.”
“Angiotensin II receptor type 2 and 4–stimulating antihypertensive medications (hereafter, stimulating medications) included: Angiotensin II receptor type 1 blockers, dihydropyridine calcium channel blockers, and thiazide diuretics.
Angiotensin II receptor type 2 and 4–inhibiting antihypertensive medications (hereafter, inhibiting medications) included: angiotensin-converting enzyme (ACE) inhibitors, ?-blockers, and nondihydropyridine calcium channel blockers.”
Editors Note: If you have hypertension and are at risk for cognitive decline, know that your choice of effective antihypertensive drugs can lead to better cognitive outcomes. Drugs that stimulate the angiotensin II receptor type 2 and 4 help prevent dementia. These drugs include:
ARB type 1, dihydropyridine calcium channel blockers, and thiazide diuretics. (Good guys)
Those that inhibit Angiotensin II receptors types 2 and 4 do not prevent dementia. These drugs include:
ACE inhibitors, beta blockers, and non-dihydropyridine calcium channel blockers. (Bad guys)
Talk with your doc about drugs equally for blood pressure control but those that also have benefits for ultimate preservation of cognition.
U.S. FDA Approves VRAYLAR® (cariprazine) as an Adjunctive Treatment for Major Depressive Disorder
“A Phase 3 Study 3111-301-001 showed a clinically and statistically significant change from baseline to week six in the Montgomery-Åsberg Depression Rating Scale (MADRS) total score for patients treated with cariprazine at 1.5 mg/day + ADT compared with placebo + ADT. A second registration-enabling study, RGH-MD-75, showed a clinically and statistically significant change from baseline to week eight in the MADRS total score for patients treated with cariprazine at 2-4.5 mg/day (mean dose 2.6 mg) + ADT compared with placebo + ADT.
Cariprazine was generally well tolerated in 6- and 8-week studies. Mean weight change was < 2lbs and ? 3% of patients had a weight increase of ? 7%.
The starting dosage of VRAYLAR is 1.5 mg once daily. Depending upon clinical response and tolerability, the dosage can be increased to 3 mg once daily on Day 15. In clinical trials, dosage titration at intervals of less than 14 days resulted in a higher incidence of adverse reactions. The maximum recommended dosage is 3 mg once daily.
Most common adverse reactions observed in the adjunctive MDD studies (? 5% and at least twice the rate of placebo) were:
Akathisia, nausea, and insomnia at the recommended doses in 6-week, fixed-dose trials
Akathisia, restlessness, fatigue, constipation, nausea, increased appetite, dizziness, insomnia, and extrapyramidal symptoms in one 8-week flexible-dose trial at a titration of less than 14 days”
Lithium is a Lifesaver in Bipolar Disorder
Batya Swift Yasgur MA, LSW reported in Medscape Medical News on November 28, 2022 that “Mood stabilizers protect against suicide and all-cause mortality in patients with bipolar disorder (BD), including natural mortality, with lithium emerging as the most protective agent, new research suggests.
Investigators led by Pao-Huan Chen, MD, of the Department of Psychiatry, Taipei Medical University Hospital, Taiwan, evaluated the association between the use of mood stabilizers and the risks for all-cause mortality, suicide, and natural mortality in over 25,000 patients with BD and found that those with BD had higher mortality.
However, they also found that patients with BD had a significantly decreased adjusted 5-year risk of dying from any cause, suicide, and natural causes. Lithium was associated with the largest risk reduction compared with the other mood stabilizers.“
Intermittent theta burst magnetic stimulation (iTBS) is FDA approved.
As reported in Psych. News:?The Food and Drug Administration (FDA) has cleared the SAINT Neuromodulation System for the treatment of refractory depression in adults, Magnus Medical Inc. (the manufacturer of the product)?announced?Tuesday. SAINT is a?modified form of transcranial magnetic stimulation?(TMS) that compresses weeks of conventional TMS therapy into just five days”. ?Regular TMS takes 20-30 minutes per daily session while iTBS takes about 5 minutes and thus can be applied many times in a single day. ?”As demonstrated in a clinical trial?published?in?The American Journal of Psychiatry, Montgomery-Åsberg Depression Rating Scale (MADRS) scores dropped by 62% among participants following five days of SAINT stimulation compared with a 14% drop among participants receiving sham stimulation. These improvements were sustained over a four-week follow-up.” ?The method was developed by Nolan Williams and he used MRI to best target the site of stimulation
Cannabidiol (CBD) does not make cannabis safer
Amir Englund et al reported in Neuropsychopharmacology in A randomised, double-blind, cross-over trial of cannabis with four different CBD:THC ratios that CBD did not protect against the adverse effect of THC. These included impaired delayed verbal recall ( p?=?0.001) and induced positive psychotic symptoms on the PANSS ( p?=?2.41?×?10–5).
Editors Note: Not only does marijuana impair memory, it is a risk factor the onset of bipolar disorder and schizophrenia. When pot is used by a person with a unipolar or bipolar mood disorder, there are increases in depression and anxiety and an overall less favorable course of illness. If a person with a mood disorder uses heavy amounts of marijuana, they could consider buying N-acetylcysteine (NAC) 500mg and increasing the dose to 1,000mg twice a day within a week as this has been shown to decrease drug use compared to placebo in adolescents and young adults using and abusing pot. Most people who sell pot, are not well-informed about its dangers and just want to make money.
Mindfulness-Based Stress Reduction Equivalent to Escitalopram for Treatment of Anxiety Disorders
Hoge et al reported in JAMA Psychiatry (2022) that in a randomized clinical trial of 276 adults with anxiety disorders, 8-week treatment with mindfulness-based stress reduction (MBSR) was noninferior to escitalopram. The “MBSR is a manualized 8-week protocol with weekly 2.5-hour long classes, a day-long retreat weekend class during the fifth or sixth week, and 45-minute daily home practice exercises…. Qualified instructors taught the theory and practice of several forms of mindfulness meditation, such as breath awareness (focusing attention on the breath and other physical sensations), a body scan (directing attention to one body part at a time and observing how that body part feels), and mindful movement (stretching and movements designed to bring awareness to the body and increase interoceptive awareness)….Escitalopram was initiated at 10 mg daily orally and increased to 20 mg daily at week 2 if well tolerated or delayed if not.” The investigators concluded that “mindfulness-based stress reduction was a well-tolerated treatment option with comparable effectiveness to a first-line medication for patients with anxiety disorders.”
Cariprazine Effective in AD-Resistant MDD
Maletic, V, et al. reported on Efficacy of Adjunctive Cariprazine Across Individual Depressive Symptoms in Major Depressive Disorder: A Post-Hoc Analysis. Poster presented at Psych Congress 2022; September 17-20, 2022.
“With 751 patients (502 on CARIPRAZINE (CAR) and 249 on PBO), the LSMD (95% CI) score change from baseline to week 6 was significant in favor of CAR. Items of the MADRS scale were assessed individually over the course of the study, including apparent sadness, reported sadness, reduced appetite, lassitude, inability to feel, pessimistic thoughts, and suicidal thoughts, showing improvement compared to PBO. “

Lithium Corrects Circadian Rhythm Abnormalities in Bipolar Depression
At a recent scientific meeting, researcher Monica Federoff described new findings about lithium’s effects in people with bipolar I disorder, especially regarding circadian rhythms. The 12-week study included 386 participants with bipolar I. Some participants responded well to lithium, but even those whose bipolar disorder did not remit saw improvements in total symptoms, depressive symptoms, and manic symptoms.
Only those who were classified as good responders to lithium treatment showed improvement in circadian symptoms. Their depression improved in the direction of more “morningness,” and the authors suggested that “stabilization of circadian symptoms of depression may be an essential feature of lithium’s therapeutic effects in [bipolar] I patients.”
