- Major depressive Disorder

- Bipolar Disorders

- Dysthymia

I major depression
I- Major depression

- Primary disturbance in mood

- Syndromes rather than disease

- Occur in cyclic fashion

- Lost sense of control

Dsm iv classification of mood disorders
DSM IV Classification of mood disorders

- Major depressive disorder ( unipolar depression ) = 2 weeks

- Hypomania = 4 days

- Bipolar I (Mania for 1 week, alternating episodes of Mania+ Mania, Mania+ MDD)

- Bipolar II( Hypomania+ MDD)

- Mixed episode = 1 week

Mood disorders



- Life time prevalence

MDD 10-15% in women Bipolar I = 0.4-1.6%

5-12% in men Bipolar II =0.5%

B- Sex


-Women : Men = 2:1

Why? Child birth, hormonal differences, psychosocial stressors

In Bipolar

- Women = men

C- Mean age of onset

Bipolar I = 30 years MDD = 40 years

Mood disorders

D- Marital Status

More in single, divorced, separated, poor interpersonal relations

E-Socioeconomic Status

No correlation for MDD, bipolar more in high SES

Depression more in rural areas

Mood disorders


A- Biological Factors

1- Biogenic amines ( levels in blood, urine,CSF)

Heterogeneous dysregulation of the biogenic amines

Low nor epinephrine, Serotonin in depression, Low dopamine in depression and high in mania

Others, GABA, Glutamate

2- Neuroendocrinal dysregulation

- Adrenal Axis ( Non suppression of dexamethasone suppression test)

- Thyroid Axis

Antithyroid antibodies, low thyroid hormones, development of rapid cycler

Mood disorders

3- Sleep EEG abnormalities

  • Delayed sleep onset , short rapid eye movement( REM ) Latency, Increased duration of 1st REM period, abnormal Delta sleep

    4- Neuroimmune dysregulation

    5- Brain imaging studies

    Enlarged ventricles and small frontal lobes, Diminished cerebral blood flow

Mood disorders

6- Genetic factors

Genetic evidence through family studies, adoption studies, twin studies.

Molecular biology: involvement of chromosome;5,11,18,X.

B- Psychosocial factors

- Life stressor commonly precede the occurrence of first MDD and bipolar disorder.

- Life events common in past history of patients : Loss of parent before the age of11 years, loss of spouse , unemployment.

Mood disorders

C- Personality factors

- OCD, histrionic, borderline predict depression
