Disruptive Mood Dysregulation Disorder
Disruptive mood dysregulation disorder (DMDD) is a childhood condition of extreme irritability, anger, and frequent, intense temper outbursts. DMDD symptoms go beyond a being a “moody” child—children with DMDD experience severe impairment that requires clinical attention.
Wiki Number: W066
Diagnosis: Disruptive Mood Dysregulation Disorder
US Patients: 1.5% children
Age Onset: Child or adolescent
Brain Area: under-activity of the amygdala at judging other’s anger or sadness; medial front gyrus and anterior cingulate cortex – lower
Symptoms: disproportionate irritable or angry moods or several temper outbursts weekly; poor stress regulation; one year or more
Progression: displays persistent anger against people and objects, often have anxiety and depression in later years
Causes: Brain areas above are important for evaluating and regulating negative emotions; poverty and single-parenthood affect it
Medications: antidepressants, antipsychotics and mood stabilizers
Therapies: None listed.

- Dysregulation of mitochondrial dynamics, mitophagy and apoptosis in major depressive disorder: Does inflammation play a role?by Giselli Scaini on October 15, 2021
Recent studies have suggested that mitochondrial dysfunction and dysregulated neuroinflammatory pathways are involved in the pathophysiology of major depressive disorder (MDD). Here, we aimed to assess the differences in markers of mitochondrial dynamics, mitophagy, general autophagy, and apoptosis in peripheral blood mononuclear cells (PBMCs) of MDD patients (n = 77) and healthy controls (HCs, n = 24). Moreover, we studied inflammation engagement as a moderator of mitochondria dysfunctions on...
- Molecular Link between Circadian Rhythmicity and Mood Disordersby Frank Faltraco on October 8, 2021
CONCLUSION: Circadian rhythms are intrinsically linked to affective disorders, such as unipolar depression and bipolar disorder.
- Cadmium attenuates testosterone synthesis by promoting ferroptosis and blocking autophagosome-lysosome fusionby Ling Zeng on October 5, 2021
Ferroptosis is a newly defined programmed cell death pathway characterized by iron overload and lipid peroxidation. Increasing studies show that autophagy regulates testosterone synthesis and promotes ferroptosis. Testosterone is essential for sexual development and the maintenance of male characteristics. The deficiency of testosterone induced by cadmium (Cd) can severely affect male fertility. However, the underlying mechanism of testosterone reduction after Cd exposure remains blurry. In this...
- Every Night and Every Morn: Effect of Variation in CLOCK Gene on Depression Depends on Exposure to Early and Recent Stressby Dorka Gyorik on September 13, 2021
The role of circadian dysregulation is increasingly acknowledged in the background of depressive symptoms, and is also a promising treatment target. Similarly, stress shows a complex relationship with the circadian system. The CLOCK gene, encoding a key element in circadian regulation has been implicated in previous candidate variant studies in depression with contradictory findings, and only a few such studies considered the interacting effects of stress. We investigated the effect of CLOCK...
