Final answer:
Cognitive-behavioral therapy for unipolar depression typically includes psychotherapy and may also involve electroconvulsive therapy, deep-brain stimulation, or medications like monoamine oxidase inhibitors and selective serotonin reuptake inhibitors.
Step-by-step explanation:
Cognitive-behavioral therapy (CBT) for the treatment of unipolar depression may include various forms of treatment. One of the core treatments is psychotherapy, specifically targeted to address cognitive processes and behaviors.
In some cases, depending on the severity and response of the individual, other treatments may be employed alongside or instead of CBT. These can include electroconvulsive therapy (ECT), deep-brain stimulation (DBS), and medication such as monoamine oxidase inhibitors (MAO inhibitors) and selective serotonin reuptake inhibitors (SSRIs). MAO inhibitors work by blocking the enzyme that degrades neurotransmitters, thereby increasing levels in the synaptic cleft, whereas SSRIs prevent the reuptake of serotonin into the presynaptic neuron, leading to increased serotonin availability.
