Free rTMS, Brain Changes in Depressed Females, Why Anti-Benzodiazepine? – 3 New Things
Last week I didn’t post three new things but don’t take that to mean I wasn’t learning because I certain was, and always am. For this week I have these three new pieces of information to share:
- Repetitive transcranial magnetic stimulation (rTMS) treatment for depression to be free for (some) Canadians
- Brain changes are noted in depressed females
- Why are some doctors anti-benzodiazepine?
1. Free rTMS in Manitoba (Canada)
RTMS stands for repetitive transcranial magnetic stimulation and is a treatment for treatment-resistant depression. RTMS is considered a neurostimulation therapy, like electroconvulsive therapy (ECT), but is non-invasive. RTMS has its pros and its cons.
- Pros – rTMS is drug-free, has few side-effects and can produce remission from depression in some people
- Cons – rTMS is expensive, intensive and its therapeutic effects are generally temporary
Cost of RTMS
Most people don’t get rTMS due to the cost. Repetitive transcranial magnetic stimulation requires 2 sessions per day for 10 days (weekends off) plus and additional possible 5-10 sessions depending on the reaction to treatment. Needless to say, this is one expensive therapy. In Canada that works out to $5000 – $7500 and in the States lord only knows how much.
And Manitoba is taking the very civilized step forward of offering rTMS as part of the public health care system, which is how it should be. The only reason why it isn’t is cost. You can get rTMS in Canada, but this is the first time I’ve heard of it being free.
Congratulations to Manitoba for taking a step forward in helping people with a mental illness. I hope this is the sign of things to come across the country.
2. Brain Changes Noted in Depressed Females
Women are twice as likely to develop depression as men but no one knows why. This study takes a look at female brains to look for biological identifying markers between depressed brains and well brains.
. . . depressed women had a pattern of reduced expression of certain genes, including the one for brain-derived neurotrophic factor (BDNF), and of genes that are typically present in particular subtypes of brain cells, or neurons, that express the neurotransmitter gamma-aminobutyric acid (GABA.) These findings were observed in the amygdala, which is a brain region that is involved in sensing and expressing emotion.
BDNF and GABA in Depressed Brains of Women
BDNF is something I’ve mentioned before as to a biological cause of depression. Yes, just another fact to chalk up for all the people saying depression is just “in your head.”
And work toward identifying the gene that contributes to depression:
. . . researchers tested mice engineered to carry different mutations in the BDNF gene to see its impact on the GABA cells. They found two mutations that led to the same deficit in the GABA subtype and that also mirrored other changes seen in the human depressed brain.
I keep telling people: We’re getting closer to effective treatments and understanding every day.
3. The Religion of Benzodiazepines – Why Some Doctors Don’t Prescribe Benzos
I’ve taken benzodiazepines (benzos) of one type or another for a decade and never once had a problem with them, but many people do develop tolerance, dependence and drug-seeking behavior around this type of medication.
My opinion is that benzodiazepine medications can be used quite safely when properly handled, but that some people have the tendency to get addicted to medications, and for them, these medications may be contraindicated. In other words, it’s down to the individual and prescription of benzos cannot be characterized as “bad” or “good” in a blanket statement.
I plan on writing a whole article about this, but if you’d like a sneak peek about why some doctors are anti-benzodiazepine, check out this article in Psychiatric Times.
