A

Mood change is pervasive and persistent; does not improve, even temporarily, when engaging in pleasurable activities. Mood change may occur without precipitating events or may be out of proportion to the person’s circumstances
Impaired ability to function in social and occupational roles.
Mood change with additional cognitive, somatic behavioural signs.
Nature or quality of mood change may be different than what’s experienced with normal stress

Q

DSM-5 beravement

A

Bereavement may induce great suffering, but it does not typically result in MDE/MDD. When they do co-occur, it may be more severe, prognosis may be worse, and it may occur in people with “other vulnerabilities” in which case “recovery may be facilitated by anti-depressant treatment”

Q

Why is Disruptive Mood Dysregulation Disorder a bad change in DSM5?

A

DSM 5 will turn temper tantrums into a mental disorder- a puzzling decision based on the work of only one research group. We have no idea whatever how this untested new diagnosis will play out in real life practice settings, but my fear is that it will exacerbate, not relieve, the already excessive and inappropriate use of medication in young children. …. DSM 5 should not be adding a new disorder likely to result in a new fad and even more inappropriate medication use in vulnerable children.

Q

why is excluding beravement a bad change in the DSM-5

A

Normal grief will become Major Depressive Disorder, thus medicalizing and trivializing our expectable and necessary emotional reactions to the loss of a loved one and substituting pills and superficial medical rituals for the deep consolations
of family, friends, religion, and the resiliency that comes with time and the acceptance of the limitations of life.

Schemas shape the relationships people enter, the approach to managing difficulties/stress and interpretation of events, expectation of positive resolution

69

70
Q

71
Q

Biological effect of the NEUROENDOCRONE SYSTEM on depression

A

—dysfunction in the hypothalamicpituitary-adrenal (HPA) axis may also play a role in the development and maintenance of depression

72

84
Q

light therapy for seasonal mood disorder

A

exposure to broad-spectrum bright light used for one-two hours per day

Q

types of Mood stabilisers for bipolar disorders

A

lithium carbonate

Anticonvulsant medications

Q

age and suicide in Australia

A
