Diagnosing Depression

Friday, August 6th, 2010

When a patient has clinical depression, she has symptoms like sadness and anger that interfere in her life. Not all forms of depression are the same: each type of depression has different diagnostic criteria, such as the duration and number of symptoms. The National Institutes of Health (NIH) states that major depression, atypical depression and dysthymia are the most common forms of depression. Another depressive disorder, seasonal affective disorder, occurs only during certain times of the year.

Major Depression

Major depression is one type of depression that occurs in both children and adults, though it is more prevalent in women, according to the NIH. To be diagnosed with major depression, the patient must have five or more symptoms of depression that last for at least two weeks. Like other psychiatric disorders, these symptoms must be a change in the person’s normal mood and behavior, and must interfere in her ability to function. Examples of major depression symptoms include agitation, problems concentrating, sleeping difficulties, changes in appetite and weight, feeling hopeless or worthless, fatigue, withdrawal from once enjoyed activities, and suicidal thoughts. If, however, the patient has only two to four symptoms, she is diagnosed with minor depression.

Atypical Depression

The NIH states that one-third of patients with depression are diagnosed with atypical depression. The main diagnostic criteria of atypical depression is mood reactivity, where the patient’s mood either improves or deteriorates in response to an event; a patient with major depression, on the other hand, only has a depressed mood. In addition to the mood reactivity, the patient must have two or more of the following symptoms: a strong reaction to rejection, overeating, oversleeping and a heavy feeling in the limbs.

Dysthymia

Dysthymia is a chronic form of depression that affects five percent of the population, according to the NIH. A patient can have just dysthymia, or dysthymia combined with another form of depression, like major depression, or a psychiatric disorder. To be diagnosed with dysthymia, the patient must have a low mood for at least two years and two other symptoms, like poor concentration, feeling hopeless, low self-esteem, fatigue, changes in appetite and sleeping problems.

Seasonal Affective Disorder

Seasonal affective disorder (SAD) is a type of depression that occurs during the winter, though a rare form of SAD occurs during the summer, according to the NIH. For a patient to have SAD, symptoms must be present for at least two years, and he cannot have depressive episodes at other points of the year. Symptoms that distinguish SAD from other depressive disorders include decreased energy and concentration in the afternoon, lethargic movement, excessive daytime sleepiness, and carbohydrate cravings.

Chemical Causes to SAD

Wednesday, August 4th, 2010

Sometimes known as the “winter blues,” people most commonly experience Seasonal Affective Disorder, or SAD, during the fall or winter, when days grow shorter and there is less direct sunlight. Research has supported the use of light therapy in treating SAD, but the precise biochemical relationship between the onset and treatment of SAD remains unclear. There appear to be four key biochemical markers of SAD.

Serotonin

Serotonin is a neurotransmitter in the brain. Levels appear to vary according to the amount of daily sunlight. In “Winter Blues: Everything You Need to Know to Beat Seasonal Affective Disorder,” Dr. Norman Rosenthal summarizes a collection of studies examining the role of serotonin in SAD. Dr. Rosenthal was the first researcher to describe SAD. People with SAD often crave carbohydrates such as sweets and starches; increased carbohydrate consumption appears to raise serotonin levels in the brain, offering support for a relationship with SAD. When people with SAD received light therapy, administering drugs that lowered serotonin levels appeared to undo light therapy treatment gains. For these reasons, antidepressants such as SSRI’s that increase serotonin levels may help to alleviate SAD.

Dopamine

SSRI’s aren’t the only class of antidepressants that affect SAD. Another antidepressant, Bupropion, that has been found to help with SAD, increases levels of dopamine in the brain. Dopamine is a neurotransmitter associated with response to pleasurable experiences.

Norepinephrine

In addition to dopamine, Bupropion increases levels of the neurotransmitter norepinephrine, which may also alleviate symptoms of SAD. Norepinephrine increases secretion of melatonin, which research has been implicated in SAD. Because neurochemical processes are so complex, it’s possible that levels of serotonin, dopamine, and norepinephrine all work in concert in creating or reducing SAD symptoms. All three are influenced by light therapy, the treatment of choice for SAD.

Melatonin

Melatonin is a naturally occurring chemical that helps to regulate the sleep-wake cycle. Secretion of melatonin increases during dark periods and decreases during light exposure. Research has found an association between melatonin levels and SAD, although the precise relationship between the two is not entirely clear.

Depression in Men vs. Women

Wednesday, July 14th, 2010

Depression occurs in the young and the old and in men and women. We do know that the rate of depression in men is less than for women.

The symptoms that men experience can be different from those that women experience. Symptoms including anger, irritability, and feeling discouraged are more common in men than symptoms of hopelessness or helplessness.

Typical symptoms we associate with depression such as depressed mood may not be present in depression in men. This can make it more difficult to recognize depression in men. Many famous men, including President Abraham Lincoln and Winston Churchill, had depression and still lived successful lives.

Unfortunately, men are not as likely as women to admit to having depression. Even if they do admit to having depression, they may be less likely to seek treatment. Men may stuff their feelings instead of verbalizing them. They may work more, gamble, or use alcohol or drugs to avoid their feelings. Their sleep and or appetite may change. They may suddenly begin talking about divorce or separation.

Women attempt suicide more often than men, but the rate of completed suicide in men is 4 times that of women. Suicide rates peak in mid life and again later in life. Men age 85 and older have the highest suicide rate.

Men want and need to be strong for their families; they don’t want to appear weak or vulnerable. If they are the primary bread winner, they can feel pressure to provide for their dependents. Of course, these general statements can be applied to women as well.

If you suspect a friend or loved one may be depressed, urge them to seek a professional evaluation. There are many options, including medication, therapy or a combination of the two.

Heart Attack Risk with Depression

Monday, July 12th, 2010

We frequently talk about the importance of treating depression. Here’s another reason to get help now.

As many as 1 out of every 3 people who have a heart attack report feelings of depression. Women, people who have had depression before, and people who feel alone and without social or emotional support are at a higher risk of depression after a heart attack.

If you have major depression and have had a heart attack, you’re at a much higher risk to die of a heart attack. Although this is very sobering, you need to know the facts. We know that chemicals in our brain are not in proper balance when depressed. When people suffer from depression, they are not as likely to take care of themselves properly. People don’t eat right and commonly don’t exercise. Sleep is usually disturbed in some way, too.

Anxiety increases heart patients’ likelihood of suffering a heart attack, stroke or heart failure.  The link between anxiety and such events can’t be explained by health behaviors like smoking, severity of disease or biological factors such as hormone levels or heart rate.

So if you have depression and heart disease, pay extra attention to your physical and mental health. Don’t put off asking for help. You and your body deserve it!

Depression & Pregnancy

Tuesday, July 6th, 2010

Pregnancy is a joyous occasion.  Pregnancy, though, does not protect women from experiencing mild to severe depression. Medication and/or therapy may be recommended.

Treating depression is always important and it can be successfully treated during and after pregnancy. Some antidepressant/anti anxiety medications can be used safely throughout pregnancy and breast feeding.

A drug free way of treating depression during pregnancy is by using a light therapy box.  Bright light therapy is as effective as the antidepressants in depression cure in pregnant women.  Bright light therapy has yielded favorable results for curing depression in pregnancy.  It also is quite safe as it does not have any side effects.  It requires a patient to sit in front of a box for about 30 minutes a day, depending on the patient.

Here are some findings from research on pregnancy and depression:

  • Babies born to moms with depression have an increased risk for irritability, less activity and attentiveness and fewer facial expressions.
  • There are possible fetal abnormalities when mothers take antidepressants in the first trimester. But there’s not a particular pattern associated with a specific medication or class of medications.

Some specific treatment recommendations include:

  • Talk to your provider early if you are planning to conceive. You can talk about the best options for you as an individual.
  • Encourage the provider who will deliver your baby and your mental health provider to consult with each other on the best options for you. They will help you understand the risks and benefits of medication versus therapy, etc.
  • If you are taking an antidepressant for depression, don’t discontinue or change your dose of medication on your own. This could be dangerous and your symptoms could worsen.
  • Use bright light therapy as a drug free option to treat your depression during pregnancy.
  • If you have severe depression and are pregnant, you should remain on medication.

Untreated depression during pregnancy has been proven to lead to higher rates of:

  • Lower birth weights
  • Pre-term labor (depression doubles the risk)
  • Increased use of alcohol and drugs to self-medicate

Please have a candid discussion with both your psychiatrist and OB-GYN regarding the benefits, risks and side effects of all medications. If you have been diagnosed with depression and are considering pregnancy, meet with your health providers before you get pregnant. This will provide peace of mind and help to make sure that you and your baby are both as healthy as possible.
