Major
Depression and Manic Depression: What's the Difference?
by
Michael G. Rayel, MD
Countless
number of patients and their family members have asked me about
manicdepression and major depression. Is there any difference?
Are they one and the same? Is the treatment the
same? And so on. Each time I encounter a chorus of questions
like these, I am enthused to provide answers.
You
know why? Because the difference between these two disorders is
enormous. The difference does not lie on clinical presentation alone.
The treatment of these two disorders is significantly distinct.
Let
me begin by describing major depression (officially called major
depressive disorder). Major depression is a primary psychiatric
disorder characterized by the presence of either a depressed mood
or lack of interest to do usual activities occurring on a daily
basis for at least two weeks. Just like other disorders, this illness
has associated features such as impairment in energy, appetite,
sleep, concentration, and desire to have sex.
In
addition, patients afflicted with this disorder also suffer from
feelings of hopelessness and worthlessness. Tearfulness or crying
episodes and irritability are not uncommon. If left untreated, patients
get worse. They become socially withdrawn and cant go to work.
Moreover, about 15% of depressed patients become suicidal and occasionally,
homicidal. Other patients develop psychosishearing voices
(hallucinations) or having false beliefs (delusions) that people
are out to get them.
What
about manic-depression or bipolar disorder?
Manic-depression
is a type of primary psychiatric disorder characterized by the presence
of major depression (as described above) and episodes of mania that
last for at least a week. When mania is present, patients show signs
opposite of clinical depression. During the episode, patients show
significant euphoria or extreme irritability. In addition, patients
become talkative and loud.
Moreover,
this type of patients doesnt need a lot of sleep. At night,
they are very busy making phone calls, cleaning the house, and starting
new projects. Despite apparent lack of sleep, they are still very
energetic in the morning ready to establish new business
endeavors. Because they believe that they have special powers, they
involve in unreasonable business deals and unrealistic personal
projects.
They
also become hypersexual wanting to have sex several times
a day. Onenight stands can happen resulting in marital conflict.
Like depressed patients, manic patients develop delusions (false
beliefs). I know a manic patient who thinks that he is the Chosen
One. Another patient claims that the President of USA and
the Prime Minister of Canada ask for her advice.
So
the big difference between the two is the presence of mania. This
manic episode has treatment implications. In fact the treatment
of these disorders is completely different. While major depression
needs antidepressant, manic-depression requires a mood stabilizer
such as lithium and valproic acid. Recently, new antipsychotics,
for example risperidone, olanzapine, and quetiapine, have been shown
to be effective for acute mania.
In
general, giving an antidepressant to manicdepressed patients
can make their condition worse because this medication can precipitate
a switch to manic episode. Although there are some exceptions to
the rule (extreme depression, lack of response to mood stabilizers,
among others), it is preferable to avoid antidepressants among bipolar
patients.
When
considering the use of antidepressant in a depressed bipolar patient,
clinicians should combine the medication with a mood stabilizer
and should use an antidepressant (e.g. bupropion) that has a low
tendency to cause a switch to mania.
