The long-term treatment of mood and anxiety disorders has been defined in three phases relating to the possible outcomes in the course of the disorders. Acute treatment can enable an improvement in symptoms (response), which may lead to remission. Continuation treatment may enable treatment to sustain remission and achieve recovery and reduce the possibility of relapse. Maintenance treatment can be viewed as long-term therapy to sustain a period of recovery and prevent recurrence. Kupfer DJ. Long-term treatment of depression.

EVIDENCE FOR MENTAL DISORDERS CAUSING
SUBSTANTIAL BURDEN GLOBALLY
• Estimated percent of DALY (Disability adjusted life years) for
Neuropsychiatric disorders world-wide:
1990 – 10.5%
1998 – 11.5%
2020 – 15%
1990 estimate of DALY lost, range from 25% in Established
Market Economies (EME) to 7% in developing countries.
1998 estimate range from 23.5% in high-income countries to 10.5%
in low/medium income countries.

Major depression is estimated to become the second largest contributor to

Disease Burden in
• Functional disability is high 1
• Disability is greater when depression co-exists
with other psychiatric conditions such as panic
disorder or generalized anxiety disorder 2, 3
• The rate of attempted suicide is 15%; this figure
rises when comorbid psychiatric disorders are
Depression…the most common psychiatric
disorder that primary care clinicians
• A prevalent and a serious psychiatric disorder
• Risk of suicide is high among individuals with depression
• Symptoms of depression are made more severe by the coexistence of anxiety
• People can experience depression at any time of life

Types of Depression in
• Anxious Depression
• Chronic Anxious Depression
• Depression with Somatic Symptoms
• Treatment Resistant Depression
• Bipolar Depression
• Commonest kind of depressive disorder in general medical
• Co-Morbid Depression and Generalized anxiety
• Often very severe disorder.
• Should be offered a sedating antidepressant.
• Depression without anxiety is less common in primary care
• May need an alerting antidepressant.
Chronic Anxious Depression
Some patients are usually well known to their doctors, have
been symptomatic for many years.
Important not to treat with many different drugs and try to
confine yourself only to those that are effective for that
These patients often have
• Intractable or insoluble life problems
• It is unreasonable to suppose that these problems will
disappear with drug treatment.
• Arrange to see these patients at Regular Intervals
• If left to themselves, they often arrive more frequently.
• Spend time with them discussing their personal problems,
• Perform physical examinations for any physical disorders
• If new physical symptoms arise.
Depression with somatic
These can be divided into two groups
• Those whose physical symptoms are part of an undoubted
• Those for whom no physical cause can be found, despite
physical examination and any necessary investigations.
• Neither group consider themselves depressed.
• They will readily admit to depressive symptoms if asked
• They improve considerably on anti-depressants.
Doctors are typically distracted by the somatic symptoms,
so that the psychiatric disorder goes undetected.
These group are best managed with Re-Attribution
Refers to any patient
Does not respond to drug treatment given at the proper dosage
for an adequate time
About one third of depressed patients fall into this category.
Have to think of an antidepressant in another category; if this
is not effective, a combination of drugs may be necessary.
Alternately refer to a psychiatrist
• These are relatively rare is general practice.
• They have experienced episodes of mania or hypomania at
some time in their past.
• They merit a psychiatric opinion,
• As antidepressants will sometimes precipitate an episode of

• Because it hurts.
• Indicates serious physical illness.
• Differential reinforcement by doctors.
• Differential reinforcement by relatives.
• Social stigma attached to emotional illness.
• Does not need to blame himself.
SOMATIC PRESENTATION IN MEDICAL
In primary care 1 in 5 new consultations are for somatic symptoms
for which no specific cause is found. ( Goldberg & Bridges 1998)
In hospital settings, medically unexplained somatic complaints are
among the most common reasons for referral from primary care.
Specific symptoms tend to cluster in medical specialties according
to the organ system.
The somatic symptoms of 1/3 of all patients seen in these clinics
remain medically unexplained at the time of discharge. (Hamilton et
Depression with Anxiety
• 60 to 90% of depressed patients
have anxiety symptoms
• Coexistent anxiety and depression
• more severe symptomology
• reduced treatment response
• worse prognosis
Profile of the Anxious Depressed
• More impaired functioning compared with
• Increased agitation, hypochondriasis,
depersonalization, chronic depression
• Reduced response to drug therapy and
• More severe and chronic illness
