Subtypes of Bipolar Disorder

Tuesday, November 16th, 2004

DYSPHORIC MANIA AND MIXED STATES –
It is possible to have the symptoms of major depression and mania at the same time. This is called a mixed, or dysphoric state. It is estimated that 31% of patients presenting with mania have a mixed state. It is characterized by distinct periods of abnormally and persistently elevated, expansive, and/or irritable mood with depression (neither is due to just drug abuse.)
While the absolute changes in the brain chemistry are not fully known, mixed mania may be associated with brain transmitters that are too high (dopamine and norepinephrine), and/or too low, (serotonin). Mixed states sometimes occur during transitions from one phase of mood to the other.
In mixed mood states it is essential to treat the mania before treating the depression. Starting treatment with an antidepressant is like throwing kerosene on a fire because it can trigger a manic state.


RAPID CYCLING –
Persons with rapid cycling have at least 4 episodes per year of mania/hypomania, and/or major depression. It is estimated that 13-20% of bipolar patients are rapid cyclers. It is more common in women, probably because women have more hypothyroidism.
Rapid cycling is frequently caused by low thyroid. Some experts recommend keeping thyroid levels within the top 25% of normal range of free T4. This can be measured by a standard blood test. Note: Many doctors only test the TSH for thyroid disorders. Testing only TSH is not adequate for secondary thyroid disorders.
Rapid cycling is difficult to treat and may respond better to a mood stabilizer than Lithium. Lamictal has the best controlled studies for treatment of rapid cycling.

Highly Recurrent Major Depression

Tuesday, November 16th, 2004

Highly recurrent major depression, especially if onset is early in life, tends to do better on mood stabilizers than antidepressants. These people tend to have more frequent and severe episodes, have a positive family history for Bipolar, and not do well on antidepressants. They are probably genetically related to someone with Bipolar. Children who become depressed are also more likely to be Bipolar.

Multiple Medications Often Needed to Control Symptoms

Tuesday, November 16th, 2004

One study found patients to be on the following to control symptoms:
One medication – 19%
2 medications – 28%
3 medications – 28%
4 or more – 25%

Bipolar Disorder Overview

Monday, November 15th, 2004

The spectrum of bipolar disorders is characterized by mood instability and impulsivity. About 1% (2 million) of the population is bipolar I. Bipolar has multiple forms. It ranges in severity from mildly disruptive to life destroying. As in other medical conditions such as diabetes and hypertension, the vulnerability to bipolar disorder is inherited. Once you have it, you have it for life. Fortunately, like hypertension, it can be medically controlled.
Mood swings usually start in the 20’s, but can start in childhood or during the teens. If depression is present in these early years, there is an increased risk of bipolar. Sometimes, the first major mood swing doesn’t occur until the 30’s or occasionally, later.
If mood is compared to room temperature, (too cold equals depression and too hot equals mania), bipolar disorder is like having a defective thermostat. The thermostat gets
stuck at one extreme (mania or depression) and the temperature (mood) goes out of control.
Mood swings can occur abruptly. They may be induced by seasonal changes, hormonal changes, certain medications (such as steroids, decongestants, antidepressants, stimulants, recreational drugs), or too much or too little sleep.
One of the biggest problems facing those with bipolar disorder is what is described as the “kindling effect.” This means that every episode of abnormal mood (low or high), increases the sensitivity of the brain’s mood regulators. This makes it easier to have mood swings in the future.
Many of my patients are unquestionably bipolar and many show no signs of the disorder. But, patients that fall in a “gray” area with some symptoms present, make pinpointing the diagnosis very difficult. These individuals often appear to be primarily oppositional, substance abusers, or have personality disorders. This group is the greatest challenge to psychiatry and requires the closest scrutiny. Because of its complexity, bipolar disorder usually needs to be treated by a Psychiatrist.

Common Behavioral Treatment for Social Anxiety Disorder

Friday, November 12th, 2004

Cognitive behavioral therapy has proven to be very effective in treating social anxiety disorder.
Behavioral therapy focuses on specific steps to lessen anxiety and reduce the likelihood of recurrence. The patient is asked to face the thing they fear (exposure), and not avoid to cope with the situation.

Patients must be willing to endure temporary increases in anxiety and other symptoms in order to attain long term reduction of symptoms. The therapy is time consuming. Hard work is required by the patient to insure symptomatic relief.
The cognitive part of therapy involves replacing negative thoughts (self-talk) with positive. e.g., Instead of, “they will think I’m stupid”, replace it with “I know I’m smart.” Optimists see things better than they are. Pessimists see things worse than they are. Realists see things as they are.
Optimists have the highest quality of life and live longer.
Exposure therapy:
Real life (in vivo)-involves having the patient place themselves in actual anxiety provoking situations until they experience at least a 50% reduction of anxiety.
Every treatment outcome study utilizing exposure has produced significant reductions in social anxiety symptoms. The therapy requires repetitive patient exposure to all anxiety triggers for best results. This will include reduction of anticipatory anxiety and increased comfort levels in social situations.
Social Skills Training-some people benefit from learning techniques to become more assertive, make small talk more effectively, improve eye contact, etc.
