MOOD RANGE

 

 

Causative Theories

 
1. Genetic
2. Neurobiological
3. Intrapersonal
4. Learning Theory
5. Cognitive Theory
6. Social-Cultural               Theory
7.Physiological      Influences
 

GENETIC THEORY

Ø  Genetic Predisposition

Ø  40-50% with unipolar depression

Ø  70% with bipolar depression

Ø  Gender: Women higher 2:1 depression

Ø  Bipolar  Gender: roughly the same

Ø  Age: Women- depression as young women-decrease with age; Men increases with age

 

Ø  Socioeconomics- Higher social classes= higher incidence of bipolar

Ø  Marital status- more common in divorced and singles ( without close supports)

Ø  Seasonality- depression peaks in Spring and Fall ( so does suicidality!)

Neurobiological Theories

1.Prefrontal cortex- decreased activity, decreased glucose metabolism, decreased blood flow in ant. Cingulate cortex leading to abnormal processing of emotions.

2.Neurotransmitters-serotonin,dopamine,norepinepherine, acetylcholine in the CNS implicated in depression. Functional decrease in depressive episode; excess during mania

3.Monoamine Oxidase deactivates neurotransmitters after their release from receptor sites: Sensitivity of receptors

 

 


Neurobiological Theories
Continued

 

Amount of available sunlight-SADS

Internal desynchronization of biological rhythms

 

Intrapersonal Theories

Anger Related to loss (real or symbolic)

 Anger turned inward and against self due to inability to express it.

 

                                                                       

Learning Theories

Girls have been socialized into being docile, nice, fitting in and not learning how to manage conflict leading to decreased coping skills and decreased self esteem

Physiological Influences
