Short Answer

Expert verified
a) Major depressive disorder is familial and probably genetic. b) Major depressive disorder is solely caused by stress. c) Major depressive disorder is not responsive to treatment. d) The main factor in major depressive disorder is an excess of cortisol. e) The main factor in major depressive disorder is excessive biogenic amines. Answer: a) Major depressive disorder is familial and probably genetic.

Step by step solution

01

Understand major depressive disorder

Major depressive disorder (MDD) is a mental health condition characterized by persistent feelings of sadness, hopelessness, and a lack of interest in activities.
02

Evaluate choice (a)

MDD is known to have familial and genetic connections. Family history of the disorder can be a risk factor, and research indicates that there might be genetic components to MDD. Thus, option (a) is a reasonable choice.
03

Evaluate choice (b)

While stress can play a role in triggering MDD, it is not the sole cause of the disorder. MDD has multiple contributing factors, including biology, genetics, and environmental factors. Therefore, option (b) is not correct.
04

Evaluate choice (c)

MDD is indeed responsive to treatment. Several types of therapies, medications, and support can help individuals manage and recover from MDD. Thus, option (c) is incorrect.
05

Evaluate choice (d)

MDD is more related to an imbalance of neurotransmitters in the brain, such as serotonin, norepinephrine, and dopamine. Cortisol, a hormone that is associated with stress, is not the main factor in MDD. Therefore, option (d) is not correct.
06

Evaluate choice (e)

Excessive biogenic amines, such as norepinephrine and serotonin, have been shown to be related to other mental disorders (e.g., bipolar disorder or schizophrenia), not MDD. In MDD, the levels of these amines are generally lower. Thus, option (e) is incorrect.
07

Choose the correct answer

Based on the evaluation of options (a) to (e), we can conclude that option (a), "Major depressive disorder is familial and probably genetic", is the correct answer.
