What Histological Changes Are Observed in Anxiety?
Anxiety disorders are characterized by excessive fear and worry. Histologically, one can observe changes in the amygdala, a brain region involved in emotion regulation. Studies have reported an increased number of neurons in the amygdala, as well as heightened neuronal activity. Additionally, alterations in synaptic plasticity and neurotransmitter systems, particularly the GABAergic and glutamatergic systems, are often evident.
