Q

Research findings from brain scan data of posttraumatic stress disorder indicates the over activity of the amygdala is not due to activated release of the fight or flight hormone cortisol, but maybe due to elevated levels of ______.

A

Norepinephrine

17
Q

Many studies have found that the hippocampus of people with MDD is reduced in volume because of loss of gray matter. Treatment with antidepressants and remission of the depressive symptoms results in restoration via ______.

A

Increased nerve growth

18
Q

A

Vicious cycle

19
Q

For treatment of major depression vagus-nerve stimulation (VNS) increases activity in a network of brain areas known to regulate mood, but has side effects during treatment stimulation including cough, neck pain, and ______, which can be reduced by adjusting the stimulation parameters.

A

Voice alteration

20
Q

Underactivity of the direct pathway of information compared to the indirect pathway in the brain area functional loop, including the prefrontal cortex, is thought to account for the obsessive thoughts that characterize OCD.

21
Q

A

Negative life events

A

Atypical or culturally unaccepted

23
Q

Research findings indicate that people suffering from major depression have higher levels of the neurotransmitter glutamate and thus the depression may be due to dysfunctions in ______ neurotransmission.

A

Glutaminergic

24
Q

Research findings lend support to the theory that dysfunction of the ______ may contribute to or account for reduced ability in processing contextual information.

25
Q

Translocator protein (TSPO), which is a marker of inflammation, levels were found to be ______ in persons with major-depressive disorder compared to levels in healthy control persons.

26
Q

In response to potential threat the hypothalamo-pituitary-adrenal axis (HPA) chain reaction includes the adrenal gland’s release of cortisol which gives rise to the activation of the ______ triggered by the sympathetic nervous system.

A

27
Q

Q

29
Q

The monoamine hypothesis posits that people suffering from major depressive disorder have depleted levels of the ______ neurotransmitters.
