A client is wondering about the genetic factors that contribute to depression. What is the relationship between genetic factors and depression according to the text?

Choice A rationale:

Pharmacological interventions involve the use of medications to treat conditions like Major Depressive Disorder (MDD). This does not involve stimulating the brain electrically or magnetically. While antidepressant medications can have an impact on neuronal activity and neuroplasticity, they are not classified as brain stimulation therapies.

Choice B rationale:

This is the correct answer. Electroconvulsive therapy (ECT) is a treatment modality that involves passing an electrical current through the brain to induce a controlled seizure. This has been found to be effective in cases of severe depression where other treatments have not worked. Other somatic therapies might include repetitive transcranial magnetic stimulation (rTMS) and vagus nerve stimulation (VNS), both of which involve modulating brain activity through electrical or magnetic means.

Choice C rationale:

Psychotherapeutic interventions involve talking therapies aimed at addressing psychological and emotional issues. These therapies do not directly involve electrical or magnetic stimulation of the brain. While they can certainly lead to changes in neuronal activity and neuroplasticity, they are not the primary modalities for brain stimulation.

Choice D rationale:

Cognitive-behavioral therapy (CBT) is a specific type of psychotherapeutic intervention that focuses on changing thought patterns and behaviors. While CBT can lead to changes in brain activity and neuroplasticity, it does not involve direct brain stimulation through electrical or magnetic means like ECT or rTMS.

Choice A rationale:

Signs of normal bereavement. Bereavement refers to the period of grief and mourning after the loss of a loved one. While fatigue and feelings of worthlessness can be experienced during bereavement, difficulty concentrating is not a typical sign. Additionally, bereavement-related symptoms typically improve over time as the individual processes their loss. The combination of extreme fatigue, difficulty concentrating, and thoughts of worthlessness suggests a more severe and persistent condition than normal bereavement.

Choice B rationale:

Symptoms of bipolar disorder. Bipolar disorder is characterized by alternating episodes of depression and mania (or hypomania). The client's symptoms of extreme fatigue, difficulty concentrating, and thoughts of worthlessness are primarily indicative of a depressive episode, which is only one aspect of bipolar disorder. Bipolar disorder requires the presence of manic or hypomanic episodes, which are not mentioned in the client's presentation.

Choice C rationale:

Indicators of substance-induced mood disorder. Substance-induced mood disorder occurs as a result of substance use or withdrawal and involves changes in mood and affect. While substances can lead to symptoms similar to depression, the combination of symptoms presented by the client (fatigue, difficulty concentrating, thoughts of worthlessness) is more indicative of a primary mood disorder rather than one directly caused by substance use.

Choice D rationale:

Criteria for diagnosing MDD according to DSM-5. The client's symptoms of extreme fatigue, difficulty concentrating, and thoughts of worthlessness align with the criteria for Major Depressive Disorder (MDD) as defined in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). These criteria include the presence of specific symptoms for a specified duration, causing significant impairment in functioning. The symptoms should not be better explained by other conditions or substances. In this case, the client's presentation closely matches the criteria for diagnosing MDD.
