How does genetics fit in?

Genetics is the study of inheritance; it’s finding out what traits are handed down from lineage and what is environmental. Everyone is affected by genetics because we all have parents, who we got our genetic traits from.

Many factions of scientists track genetics through the generations. Most use a “genogram”for a reference for their research in one line or for one person. A genogram is like a family tree in that you put all of your ancestors, siblings, and relatives into the chart. Then, you track who had the trait in question and who may have had the trait but was unconfirmed. The creator may use interviews with family, birth & death records, as well as criminal records and past diaries to fill in the blanks. This is usually a good way to find out if a trait is environmentally induced or if it is genetic.

Talking about and noticing these types of traits gets me jazzed. I have my Bachelors of Science in Chemistry with an emphasis in DNA analysis & Criminalistics. Genetics was my favorite college course because the connections are so interesting. When you know a lot about a subject, it becomes more interesting. Plus, genetics is kind of a puzzle with clues as far as I’m concerned; it’s like a mystery novel.

It got even more interesting for me when Jeremy and I started talking about mental illness. He and I are both strong believers that mental illness can be both genetic and environmental. How this is described in the scientific world is usually comparison of expressivity and penetrance. In layman’s terms, expressivity is how much an individual displays a given gene trait and penetrance is how many individuals in a genetic pool are likely to have the gene for that trait.

This is where most average people hit a wall right now. There hasn’t been a phenomenal wealth of research done on the genetics of most mental illnesses. There are also a lot of barriers to proper diagnosis of mental illnesses because of the lack of research.

The National Institute of Mental Health, a division of the National Institute of Health (NIH) is trying to remedy that. They have greatly increased their research basis in the fields of mental health in the last 10 years. As a result, new medicines, treatments, and diagnosis protocols are being created every day.

Now, we are hoping to be a part of some of the research. The NIMH is currently running a research study called “Investigating the Genetics of Bipolar Disorder in those affected and their family members”. Finding this study has really opened our eyes to how our family members, primarily Jeremy’s family of origin, may be affected by Bipolar disorder. We’re hoping they will also partner with us to help with this study.

To really understand why we’re interested in it so highly, we need to talk some about Jeremy’s illness. He was diagnosed at 28 years old after years of struggle. He was divorced, had two children, worked the same job for 8 years, and had recently lost another relationship. When first treated, he was treated only for depression. He was given Effexor. As was common with this medication, when Jeremy still didn’t feel “well”, they increased his dosage. The more they increased it, the more his symptoms grew. He started having days and weeks of mania, very high anxiety and agitation, and delusional thoughts. One day he couldn’t take it anymore and he was taken to the hospital.

He ended up in an inpatient psychiatric treatment program. This is what you’d do for anyone with a severe illness; for severe pneumonia, they’d go to the PICU; for an infection they’d stay in the ICU. Think of inpatient treatment as the Intensive care unit for psychiatric cases. While there, he participated in many tests and many group sessions, as well as individual counseling. The psychiatrist determined that his response to Effexor was because he wasn’t depressed; he has bipolar disorder or cycling manic-depression.

Finding the right diagnosis makes it a lot easier to get the right treatment, but it is still not easy. Many of you have read my entry here about the mental illness in our life and the treatments we are currently seeking for it. There are hundreds more treatment options that we haven’t had to seek out yet. There are also a lot that we have tried that have not helped a lick. While in the hospital, the doctors tried many different medicines with Jeremy. Since going back on medication in 2012, there have been a few more added to the list. For some, they never find the “right” medicine for them. We are grateful that Jeremy’s found one that helped him.

Now, bring in the fact that his children struggle with illness too. The youngest is currently in residential treatment. Over the last month, the doctors there have reached out to see parallels between Jeremy’s evolution with mental illness and his son’s. In turn, they tried the medicine that’s been helping Jeremy. Lo and behold, his son has started to see some progress with impulse control and mood stabilization. That got me thinking of genetics.

When I started searching information on genetics and bipolar disorder, I found the study on the NIH site. Jeremy and I have discussed a little how his illness may be genetic. We have looked at his kids dealing with what the do, but we’ve also taken information from his family about some of Jeremy’s relatives and possible mental health issues.

Mental health is just becoming something that is viewed as a health issue instead of a stigmatized character flaw or weakness. In generations past, people were billed as “crazy”, “unstable”, or “psycho”. They were pushed out of society because of their odd behaviors or ideas. People with mental illness were avoided instead of being understood. There may well have been quite a few people who had some high functioning form of mental illness that were just outcast because of their odd life. Even in more recent generations, such as our parents, people with mental illness often didn’t seek diagnosis and treatment because of the stigma attached to it.

That’s what a genogram looks at. Jeremy and I both believe that doing this kind of exercise could be very telling for our family. We are hoping that this NIH study will accept him as part of the study; we are also hoping that some of his family members will join him in participating if they can. It would be telling to find out if there are genetic markers for bipolar disorder. To have a definitive way to diagnose this horrible disease would be one step in the right direction for a viable treatment.

Until then, we’ll keep doing what we can find that helps; we’ll be working on running the race that God has put in front of us. Stay safe out there, my friends. We’ll see you on the road.
