Optimal psychiatric treatment: Target the brain and avoid the body

Pharmacotherapy for psychiatric disorders is a mixed blessing. The advent of psychotropic medications since the 1950s (antipsychotics, antidepressants, anxiolytics, mood stabilizers) has revolutionized the treatment of serious psychiatric brain disorders, allowing certain patients to be discharged to the community after a lifetime of institutionalization.

Potentially intolerable adverse effects of psychotropic medications

However, like all medications, psychotropic agents are often associated with various potentially intolerable symptoms (Table 1) or safety complications (Table 2) because they interact with every organ in the body besides their intended target, the brain, and its neurochemical circuitry.

Potential safety complications of psychotropic medications

Imagine if we could treat our psychiatric patients while bypassing the body and achieve response, remission, and ultimately recovery without any systemic adverse effects. Adherence would dramatically improve, our patients’ quality of life would be enhanced, and the overall effectiveness (defined as the complex package of efficacy, safety, and tolerability) would be superior to current pharmacotherapies. This is important because most psychiatric medications must be taken daily for years, even a lifetime, to avoid a relapse of the illness. Psychiatrists frequently must manage adverse effects or switch the patient to a different medication if a tolerability or safety issue emerges, which is very common in psychiatric practice. A significant part of psychopharmacologic management includes ordering various laboratory tests to monitor adverse reactions in major organs, especially the liver, kidney, and heart. Additionally, psychiatric physicians must be constantly cognizant of medications prescribed by other clinicians for comorbid medical conditions to successfully navigate the turbulent seas of pharmacokinetic interactions.

I am sure you have noticed that whenever you watch a direct-to-consumer commercial for any medication, 90% of the advertisement is a background voice listing the various tolerability and safety complications of the medication as required by the FDA. Interestingly, these ads frequently contain colorful scenery and joyful clips, which I suspect are cleverly designed to distract the audience from focusing on the list of adverse effects.

Benefits of nonpharmacologic treatments

No wonder I am a fan of psychotherapy, a well-established psychiatric treatment modality that completely avoids body tissues. It directly targets the brain without needlessly interacting with any other organ. Psychotherapy’s many benefits (improving insight, enhancing adherence, improving self-esteem, reducing risky behaviors, guiding stress management and coping skills, modifying unhealthy beliefs, and ultimately relieving symptoms such as anxiety and depression) are achieved without any somatic adverse effects! Psychotherapy has also been shown to induce neuroplasticity and reduce inflammatory biomarkers.1 Unlike FDA-approved medications, psychotherapy does not include a “package insert,” 10 to 20 pages (in small print) that mostly focus on warnings, precautions, and sundry physical adverse effects. Even the dosing of psychotherapy is left entirely up to the treating clinician!

Although I have had many gratifying results with pharmacotherapy in my practice, especially in combination with psychotherapy,2 I also have observed excellent outcomes with nonpharmacologic approaches, especially neuromodulation therapies. The best antidepressant I have ever used since my residency training days is electroconvulsive therapy (ECT). My experience is consistent with a large meta-analysis3showing a huge effect size (Cohen d = .91) in contrast to the usual effect size of .3 to .5 for standard antidepressants (except IV ketamine). A recent study showed ECT is even better than the vaunted rapid-acting ketamine,4 which is further evidence of its remarkable efficacy in depression. Neuroimaging studies report that ECT rapidly increases the volume of the hippocampus,5,6 which shrinks in size in patients with unipolar or bipolar depression.

Neuromodulation may very well be the future of psychiatric therapeutics. It targets the brain and avoids the body, thus achieving efficacy with minimal systemic tolerability (ie, patient complaints) (Table 1) or safety (abnormal laboratory test results) issues (Table 2). This sounds ideal, and it is arguably an optimal approach to repairing the brain and healing the mind.
