Preliminary evidence for persistent abnormalities in amygdala volumes in adolescents and young adults with bipolar disorder

In a separate group of healthy individuals, they used genotyping and neuroimaging to examine potential genetic associations with amygdala volume in 1048 subjects and amygdala function in a subset of more than 100 subjects.

The researchers found that in patients with SAD, brain volume and activity in the amygdala decrease as a result of ICBT.

A larger network of Facebook friends correlates with a greater volume of gray matter in the amygdala, an emotion - processing region, according to a recent study.

Specifically, males on average had larger volumes and higher tissue densities in the left amygdala, hippocampus, insular cortex, putamen; higher densities in the right VI lobe of the cerebellum and in the left claustrum; and larger volumes in the bilateral anterior parahippocampal gyri, posterior cingulate gyri, precuneus, temporal poles, and cerebellum, areas in the left posterior and anterior cingulate gyri, and in the right amygdala, hippocampus, and putamen.

Specifically, individuals diagnosed with major depression have smaller hippocampal and amygdala volumes (34,35), structural and morphological changes in the prefrontal and orbitofrontal cortex (22), and basal ganglia structures (6).

The same team of Harvard researchers also found that mindfulness meditation decreases brain cell volume in the amygdala, the part of our brain responsible for fear, anxiety and stress.

To investigate the effects of poverty on childhood brain development and to begin to inform the mediating mechanisms of these negative effects, we investigated associations between poverty and total white and total cortical gray matter volume, as well as hippocampus and amygdala volumes, in a sample of children ages 6 to 12 years followed up longitudinally since the preschool period.

There are differences across studies in reported amygdala volumes as well.

A few studies have investigated the effects of early caregiving on amygdala and hippocampal volumes in children.

Stress paradigms in rodent models have been associated with elevated anxiety and contrasting alterations in neuronal morphology in the hippocampus and amygdala, with dendritic atrophy observed in the hippocampus and increased dendritic arborization in the amygdala.12, 13 Developing rodents deprived of maternal nurturance show decreased hippocampal volume and altered stress reactivity.14 An epigenetic mechanism for this effect has been elaborated.15 Importantly, controlled trials that have randomized institutionalized toddlers to early therapeutic foster care vs institutionalization have documented the deleterious effects of early relative deprivation on cognitive outcomes.16

For children's left amygdala volume, including the income - to - needs ratio at step 2 resulted in a significant increase in the amount of variance accounted for (change F1, 120 = 6.28, P =.01).

For right amygdala volumes, the increase in variance accounted for after including the income - to - needs ratio at step 2 only approached significance (change F1, 127 = 2.79, P =.09).

A recent fMRI study showed that the MAOA genotype at risk for impulsivity and violent behavior is associated with reduced gray matter volumes in limbic regions such as the amygdala, dorsal anterior cingulated cortex (dACC), and subgenual ACC and greater amygdala and subgenual ACC responsivity to negative emotional faces [25].

Specifically, we found that smaller hippocampus volumes and greater responses to sad faces in emotion reactivity regions predict increased depressive symptoms at the time of scan, whereas larger amygdala volumes, smaller insula volumes, and greater responses in emotion reactivity regions predict decreased emotion regulation skills.

Negative correlations have been reported between bilateral amygdala volume and life history of aggression (Matthies et al., 2012) and between trait anger and local gray matter volume in the left amygdala (Reuter et al., 2009) in healthy subjects.

A negative correlation between aggressiveness and local gray matter volume in the left amygdala has been reported for adolescents with conduct disorder (Sterzer et al., 2007).
