When a patient develops depression, there is a chemical imbalance in the brain that is resulting in reacting …show more content…
The areas infected by psychiatric illnesses include the amygdala, the thalamus, and the hippocampus. The amygdala is located deep in the brain and is associated with one’s emotions. “The amygdala is activated when a person recalls emotionally charged memories” (“What Causes Depression” 2), memories in which spike an increase in neurotransmitters and never settles back down even after the memory is over. The amygdala activity is typically higher when a patient is depressed, and increased activity in the amygdala continues even if one recovers fully from depression. The next affected area in the brain is the thalamus. The thalamus is where most of the sensory information is received. When the information is received, it is then sent to the “appropriate part of the cerebral cortex” (“What Causes Depression” 2) in which “directs high-level functions such as speech, thinking, and learning” (2). Information being received and transferred to the next area in depressed patients may result in neurotransmitters that are ineffective, oversensitive, or insensitive: which then leads to the signal being inhibited or suppressed. Neurotransmitters being inhibited or suppressed prevents the
