Shocking!
I had a really interesting day yesterday. I went to Richmond to learn about electroconvulsive therapy, or ECT. Yes, shock treatments. Now we have ECT in Baltimore, and all residents see patients on the inpatient unit who have ECT, and all residents do ECT. I wanted to see it again because it's been a long time since I was a resident in an ECT suite, and thought perhaps something might have changed. Nothing changed, except that now the psychiatry resident spends a lot of time looking at a computer. Why did I go to Richmond? I'm doing research for our book on involuntary treatments, ...

Looking for People to Talk to Me about Involuntary Electroconvulsive Therapy (ECT or "shock" treatments)
As our regular readers may know, we are working on a book called Committed: The Battle Over Forced Psychiatric Care. In Maryland, there is no provision for people to have ECT against their will, it's a voluntary procedure and someone else can't sign you up. Before I learned about it from Shrink Rap readers, I didn't realize that there are other states where ECT can be court-ordered and done against a patient's will. I'm interested in talking to people about their experiences with involuntary ECT. Anyone with a personal story is invited -- patients who've had it (court-ordered, not cases where people...

5 Essential Remedies for Treating Depression: Coming Back from the Brink
Graeme Cowan suffered through a five-year episode of depression that his psychiatrist described as the worst he has ever treated.
Part of his recovery involves helping people build their resilience and mental fitness as the Director of R U OK? In his book, Back From the Brink: True Stories and Practical Help for Overcoming Depression and Bipolar Disorder, he offers advice gleaned from interviews with 4,064 people who live with mood disorders.
He asked the respondents to rate the treatments they had tried and how much each had contributed to their recovery. Here’s what he found.
The following were the top eleven mos...

Medical sources of electromagnetic interference (EMI) to pacemakers / ICD
(implantable cardiovert-defibrillator) include:
a) Electrocautery: Interference can be reduced placing the indifferent electrode as far away from the pacemaker and better still by using bipolar cautery instead of unipolar cautery.
b) Radio-frequency ablation
c) Radiation therapy
d) Electrical nerve and muscle stimulators
e) Dental instruments
f) Spinal cord and deep brain stimulators
g) Defibrillators

Can Any Good Come From Depression?
Focusing on the negative elements of depression is easy. They include inertia, feelings of hopelessness, worthlessness and despair; the fun being sucked out of life. And worse, when it just feels too painful to go on living.
Often — and understandably, especially in our darkest moments — depression in whatever form feels like something from which we can’t learn anything or harness the experience of for the benefit of ourselves or others.
We may become depressed because we are depressed and the world and our prospects seem bleak from where we see things. That thought process and perspective alone doesn’t he...

When Should You Go to the Hospital for Severe Depression?
Knowing when to commit yourself or a loved one to the hospital to be treated for severe depression can be a very gray area. I wish there were a set of directions much like those when you are in labor: if contractions come within five minutes of each other and last a minute, pack your bags.
Some physicians will make the decision for you, but usually it is up to you. Here are a few guidelines.
1. When you are in danger of hurting yourself or someone else.
If you are very suicidal and have gone as far as making plans, you should be in a safe place where you don’t have to rely on sheer willpower. All of us who have experie...

3 Reasons Why Not All Mental Health Professionals are Created Equal
The biggest regret of those who have lived through a depressive or bipolar disorder episode is that they didn’t obtain a rigorous diagnosis and treatment plan early enough.
Lora Inman is one such person, interviewed in my book Back From The Brink. A long-time depression sufferer and passionate mental health advocate, she went for decades without a proper diagnosis or treatment, which prolonged her suffering and made postpartum depression even harder to manage.
Lora’s story perfectly illustrates three very good reasons why you need a trusted mental health professional.

Brain training via mindfulness, cognitive training, and/ or tDCS
Several recent media articles highlight the growing interest in a variety of approaches to enhance the brain and the mind. The obvious emerging question, which we address at The SharpBrains Guide to Brain Fitness given that “one size doesn’t fit all” is, what works best for whom and for what?
Mindfulness: Getting Its Share of Attention (The New York Times):
“The Marine Corps is testing Mind Fitness Training to help soldiers relax and boost “emotional intelligence,” the buzzwords of the hour. Nike, General Mills, Target and Aetna encourage employees to sit and do nothing, and with classes that show them how. ...

When electroconvulsive therapy is the right choice
At the end of medical school, when it was time to choose my specialty, I was torn between psychiatry and internal medicine. Psychiatry seemed most suited to my interests and aptitudes. Focusing on the mind and mental illness bridged my interest in the big questions of human existence and the practice of medicine. On the other hand, it was hard to see how being a psychiatrist would fit with the vision of being a medical missionary that motivated me to become a doctor in the first place. I, therefore, chose to receive the broader training that internal medicine would provide.

Transcranial Direct Current Stimulation: A New Electrical Treatment for Depression?
When electricity and the brain are mentioned in the same sentence, your mind might immediately jump to disturbing images of people receiving huge shocks while covered in electrodes, strapped to tables.
But electroconvulsive therapy (ECT) treatment has developed considerably since the days depicted in “One Flew Over the Cuckoo’s Nest.” A current study at JAMA Psychiatry examines a treatment called transcranial Direct Current Stimulation (tDCS).
Could this fairly new form of electrical treatment for depression really be effective — and without the negative side effects of ECT?
This new treatment, w...

A Pep Talk for Those With Treatment-Resistant Depression
In his book, Understanding Depression: What We Know And What You Can Do About It, J. Raymond DePaulo Jr., M.D. asserts that for the 20 percent of his patients who are more difficult to treat, or “treatment-resistant,” he sets an 80 percent improvement, 80 percent of the time goal. And he usually accomplishes that.
Now, if you’re not someone who has struggled with chronic depression, those stats won’t warrant a happy dance.
But if you’re someone like myself, who assesses her mood before her eyes are open in the morning, hoping to God that the crippling anxiety isn’t there, then those numbers will have you singi...

A Short Rise Out of Depression
Here's another one to file under "What we don't know about brain chemistry". That's a roomy category for sure, which (to be optimistic about it) leaves a lot of room for discovery. In that category are the observations that ketamine seems to dramatically help some people with major depression. It's an old drug, of course, still used in some situations as an anesthetic, and also used (or abused) by people who wish to deliberately derange themselves in dance clubs. Chemists will note the chemical resemblance to phencyclidine (PCP), a compound whose reputation for causing derangement is thouroughly deserved. (Ketamine was, in...
