Biological theory of Depression
Deficiency of norepinephrine, serotonin, and dopamine has been implicated
Excessive cholinergic transmission may also be a factor
-Body under stress; expends neurotransmitters
Biochemical Factors of depression
possible failure within the hypothalamic-pituitary-adrenocortical axis
-stressful anxious things happen to them
Possible diminished release of thyroid-stimulating hormone
Neuroendocrine disturbances
Cognitive theory:
Views primary disturbance in depression as cognitive rather than affective
3 cognitive distortions that serve as the basis for depression:
- Negative expectations of the environment
- Negative expectations of the self
- Negative expectations of the future
before neurotransmitters where discovered factors in depression
Psychosocial theories
