before age 18.
ne
Endocrine dysfunction Theory - Probably related to etiology of MDD
la
Sleep disturbances, appetite disturbances, libido disturbances, lethargy, anhedonia are
neurovegitative symptoms that are related to functions of the - Hypothalamus and
sh
pituitary gland secretions
Sp
ne
Endocrine dysfunction and pregnancy - A high incidence of postpartum mood
disturbances is suggested with this
la
tz
Hypothalamic-pituitary-adrenal axis (HPA) - A theory of MDD, may be a result of an
abnormal stress response related to dysregulation of this system sh
Sp
ne
HPA axis - Controls the physiological response to stress and is composed of
interconnective feedback pathways between the hypothalamus, pituitary gland, and
la
adrenal gland.
Hypothalamus releases - corticotropin-releasing hormone (CRH)
sh
Sp
Adrenocorticotropin hormone (ACTH) - Released by pituitary in response to CRH by
ne
hypothalamus
a
Cortisol - Released by adrenal glands in response to ACTH by pituitary gland

Sp
ne
Elevated cortisol levels - Over time damages the CNS by altering neurotransmission
la
and electrical signal conduction. Cortisol over time can cause changes in size and
function of brain tissue
sh
Sp
Dexamethasone suppression test (DST) - Not commonly used in clinical practice for
screening of depression as it is too non specific.

comorbidity in individuals who have experienced these events

What is the Chronobiological theory of MDD - Desynchronization of the circadian
rhythms produces the symptom constellation collectively called MDD

Sp
Circadian rhythms control these biological processes that are frequent problems with

depressed individuals - Sleep-rest cycle disturbances * Increased cortisol secretions *
REM abnormalities Increased emotional reactivity
