Objectives Over the past two decades, there has been tremendous growth in research regarding bipolar disorder (BD) among children and adolescents (ie, pediatric BD [PBD]). The primary purpose of this article is to distill the extant literature, dispel myths or exaggerated assertions in the field, and disseminate clinically relevant findings. Methods An international group of experts completed a selective review of the literature, emphasizing areas of consensus, identifying limitations and gaps in the literature, and highlighting future directions to mitigate these gaps. Results Substantial, and increasingly international, research has accumulated regarding the phenomenology, differential diagnosis, course, treatment, and neurobiology of PBD. Prior division around the role of irritability and of screening tools in diagnosis has largely abated. Gold-standard pharmacologic trials inform treatment of manic/mixed episodes, whereas fewer data address bipolar depression and maintenance/continuation treatment. Adjunctive psychosocial treatment provides a forum for psychoeducation and targets primarily depressive symptoms. Numerous neurocognitive and neuroimaging studies, and increasing peripheral biomarker studies, largely converge with prior findings from adults with BD. Conclusions As data have accumulated and controversy has dissipated, the field has moved past existential questions about PBD toward defining and pursuing pressing clinical and scientific priorities that remain. The overall body of evidence supports the position that perceptions about marked international (US vs elsewhere) and developmental (pediatric vs adult) differences have been overstated, although additional research on these topics is warranted. Traction toward improved outcomes will be supported by continued emphasis on pathophysiology and novel therapeutics.

“…The expression of neurotrophic and differentiation factors such as BDNF, NGF and ßIII tubulin, NSE, and TH, respectively warrants the advent of neuronal morphology [Tsokos et al, ; Franco et al, ; Knelson et al, ; Inal‐Emiroglu et al, ]. Thus, we have measured mRNA levels of these factors in RA treated IMR‐32 cells in which TPD52 expression is altered exogenously.…”

Tumor protein D52 (TPD52), a proto-oncogene is overexpressed in a variety of epithelial carcinomas and plays an important role in cell proliferation, migration, and cell death. In the present study we found that the treatment of IMR-32 neuroblastoma (NB) cells with retinoic acid (RA) stimulates an increase in expression of TPD52. TPD52 expression is detectable after 72 h, can be maintained till differentiation of NB cells suggesting that TPD52 is involved in differentiation. Here, we demonstrate that TPD52 is essential for RA to promote differentiation of NB cells. Our results show that exogenous expression of EGFP-TPD52 in IMR-32 cells resulted cell differentiation even without RA. RA by itself and with overexpression of TPD52 can increase the ability of NB cells differentiation. Interestingly, transfection of IMR-32 cells with a specific small hairpin RNA for efficient knockdown of TPD52 attenuated RA induced NB cells differentiation. Transcriptional and translational level expression of neurotropic (BDNF, NGF, Nestin) and differentiation (β III tubulin, NSE, TH) factors in NB cells with altered TPD52 expression and/or RA treatment confirmed essential function of TPD52 in cellular differentiation. Furthermore, we show that TPD52 protects cells from apoptosis and arrest cell proliferation by varying expression of p27Kip1, activation of Akt and ERK1/2 thus promoting cell differentiation. Additionally, inhibition of STAT3 activation by its specific inhibitor arrested NB cells differentiation by EGFP-TPD52 overexpression with or without RA. Taken together, our data reveal that TPD52 act through activation of JAK/STAT signaling pathway to undertake NB cells differentiation induced by RA. J. Cell.

“…On the other hand, more recent studies have not found differences in BDNF serum levels between PBD and controls [80][81][82] nor an association between BDNF levels and symptoms of mania or depression [83]. These studies though did report associations between BDNF in serum and inflammatory markers [83], amygdala volume [81], risk factors for cardiovascular disease and measures of executive function [82]. They do not however, refute Pandey et al [79] as they measured BDNF in serum versus lymphocytes and participants in these latter studies could be euthymic or medicated.…”

Among aggressive youths with severe mood lability who frequently fail to benefit from mood stabilizers and antipsychotics there is a discrete subtype called 'Thermoregulatory Fear of Harm Mood Disorder' (FOH). This disorder is characterized by an underlying thermoregulatory deficit, a specific prodromal sequence and a unique constellation of symptoms.The underlying problem appears to be a deficit in thermoregulation resulting in excessive heat that manifests as thermal discomfort in neutral ambient temperatures and moderate to extreme cold tolerance, and produces REM sleep-related problems and parasomnias, such as night-terrors and hypnogogic hallucinations. Clinically, FOH is associated with the advent in childhood of frequent, recurrent, vivid nightmares with themes of pursuit and abandonment. The apparent psychological sequelae of exposure to this frightening imagery is fear sensitization and auto-traumatization. A developmental sequence of fear based defensive behaviors arises and includes obsessive bedtime rituals, fear of the dark, separation anxiety, contamination fears, hypervigilance, perfectionism, misperception of neutral stimuli as threatening, as well as reactive aggression in response to limit setting and perceived threat or loss. Ketamine, chosen as a potential treatment because of its effectiveness in reducing fear sensitization and dose-dependent lowering of body temperature in preclinical studies, has been associated with sustained Journal of Psychiatry and Brain Science 2 of 43 J Psychiatry Brain Sci. 2019;4:e190004. https://doi.org/10.20900/jpbs.20190004 improvement in otherwise refractory youths. We present a detailed description of this heritable disorder, link its clinical features to a potential disturbance in brain derived neurotropic factor (BDNF) and orexin, and indicate how ketamine rapidly affects BDNF through multiple mechanisms, to produce a dramatic beneficial response in youths with this disorder.
