Which type of genetic disorder is bipolar disorder?

Genetics of Bipolar. Although results inconsistent, many earlier studies suggest chromosomal aberrations (specifically chromosome 6q & 8q21). Most studies suggested heterogeneity (several genes involved, specifically those for serotonin, Dopamine & glutamate. Also, there is strong correlation with advanced paternal age, suggesting genetic mutations.
Unknown. Although bipolar d/o is felt to be hereditary, it can also occur in individuals without a family history. Bipolar d/o is considered to be a mood disorder. The cause of the condition is not known, nor is there a genetic test for it.

Could I be born with a genetic predisposition to bipolar disorder?

Yes. There's an incompletely understood genetic connection in bipolar disorder. The most convincing evidence is studies of monozygotic twins, in which there's increased likelihood of bipolar disorder in both twins if one presents with this disorder. Children of bipolar parents are at higher risk than others, of developing a mood disorder. Growing up with a bipolar parent brings risks also. Read more...

What is the empirical evidence that there is a biological/genetic component to bipolar disorder?

Great question. Three kinds: 1) familial: concordance rates for twins adopted apart, in-family twins, sibs and unrelated; 2) gene-linkage studies to chromosomal regions (polygenic, so v. Complex) 3) drug effects in animals, e.g., mice with mutant clock gene displayed mania-like behaviors reversed by lithium (relates bipolar cycling to circadian effects in general). Read more...

Are there different forms of severity in bipolar disorder? And can it be genetic?

Yes, there are. Different forms and severity, and even cycling speed, of bipolar disorder. Some folks are more manic and some more depressed. While we are making strides w/neuroscience, we don't know the exact cause and why some folks have more pronounced symptoms than others. Peace and good health. Read more...
Yes and yes. The course of illness varies amongst individuals. This includes the severity of symptoms as well as the resulting disability. Bipolar disorder is a highly heritable (ie genetic) illness. In identical twins if one has bipolar disorder then there is a 60-80% chance the other will too. This rate is 50% for schizophrenia. Read more...

How do I know if I have a genetic predisposition to bipolar disorder?

Family History. If you have a so-called first-degree relative (sibling, mother, or father), with bd your genetic "loading" for bd is higher than if you don't. However, lots of people have bd with no known family history; and, even if both your mother and father have bd, the risk that you will too still is only about 20%--way higher than the general population but not a sure thing.

What are the different types of medication for bipolar disorder?

Many. Lithium, depakote, olanzapine, which helps with severe or psychotic depression, aripiprazole, risperidone, ziprasidone, Clozapine (should be used infrequently), some ssri's & Lamotrigine (watch out for serious rash), which seems to be more effective for depressive than manic symptoms. Always consult w/ prescribing doc before changing/adding meds since BP is a serious disorder. Read more...
Mood stabilizer. Most common are lithium, depakote, or lamictal. Seroquel and Abilify (aripiprazole) are also used. Many other options if side effects or inadequate response to any of these. Antidepressants may cause mania if given alone without mood stabilizer, but are often given along with a mood stabilizer. Unfortunately all medications have potential side effects and is always risk vs benefit. Compliance is crucial. Read more...

What are effective treatments for type 2 bipolar disorder while pregnant?

Tricky... This is a very tricky situation because most medications are not safe in pregnancy. Depending on severity of symptoms, you may need to reduce to a basic ssri with close monitoring of symptoms. Some docs will also okay ECT for very severe symptoms but this is controversial. Read more...

What type of medications do people with ADHD take if they also have bipolar disorder?

Protective meds. I have treated some people with bipolar disorder with stimulants or antidepressants for their adhd. But i would not start that medication until they are stable on either mood stabilizers or atypical antipsychotics to prevent flipping into mania or hypomania. Read more...
Risky, d/w your doc. The same medications as those without Bipolar: alpha-agonists, stimulants, atomoxetine, and antidepressants. As previously noted, such agents are usually only introduced when the person is not manic/hypomanic and they have appropriate mood stabilization on board. Lack of ongoing illicit substance use, and sleep regulation are also important. There would still be risks of activating a mood episode. Read more...

Are there really two types of bipolar disorder?

Bipolar Disorder. There are three types of bipolar disorder: bipolar 1 disorder, bipolar 2 disorder, and cyclothymic disorder. Does that answer your question, or is there really something else you want to know that you're possibly hesitant to ask, or find out? Isn't it interesting that this question has been waiting for awhile to be answered? Read more...
Bipolar Disorder. is really a spectrum. Bipolar I can have devastating sxs if not treated. Bipolar II Disorder, Bipolar Disorder Not Otherwise Specified and Cyclothymic Disorder all have cyclic changes of mood and energy in common. Read more...
Yes. Bipolar I and bipolar II, In the first, manic phases are more severe, and in the second, depressive phases are more severe.
