Increased basal ganglia activity is often a finding we have seen with anxiety disorders. When there is increased activity on the left side it is often associated with anxiety and irritability (expressed anxiety) and when there is increased activity on the right side there is often anxiety, social withdrawal and conflict avoidance.
Increased activity in the temporal lobe area has also been associated with anxiety. When there is also increased cingulate activity a person may have significant trouble with “cognitive fusion” and repetitive thoughts or rumination about anxiety.
