Preventing brain damage in psychosis


 

I read with great interest Dr. Nasrallah’s editorial, “FAST and RAPID: Acronyms to prevent brain damage in stroke and psychosis” (From the Editor, Current Psychiatry, August 2018, p. 6-8). It makes me wonder about the ethics of allowing patients with active psychosis to participate in placebo-controlled studies. If a patient’s brain undergoes damage while psychotic, allowing the psychosis to continue without active treatment sounds possibly at odds with a physician’s oath. If a patient is in the placebo arm, then they are not receiving treatment for their psychotic symptoms. I wonder about his opinion on this.

Thank you, Dr. Nasrallah, for your incisive thinking and for bringing our attention as psychiatrists to the crucial issues of our clinical practice. I’d like to offer some nuance on the RAPID acronym. First, I’d like to counterpropose DASH: Delusions, Auditory hallucinations, Strange behavior, Hospital now. This is more in line with getting physicians to tune in to the symptoms that should alarm them and bring them to action. I agree that neurodegeneration and illness recurrence are the problems to address. One unsettled issue remains: With early intervention, can we eventually taper patients off antipsychotics to spare them the metabolic and immune morbidity associated with these medications? There is some evidence that this is possible, but it is difficult to collect data. One of the factors delaying treatment, other than lack of recognition, is the general public’s belief that the treatment is sometimes worse than the disease. If we can address this issue in a nuanced fashion, we may get more “early adopters” of these neuron-sparing treatments.

Dr. Nasrallah is right to focus on brain injury patterns, including inflammation and de-myelination, during psychotic episodes. He and Dr. Roque note that starting a patient on a long-acting injectable antipsychotic as soon as possible may prevent subsequent relapse and further brain damage. However, their editorial omits 2 treatments—minocycline and clemastine—that can help stop CNS inflammation, reduce brain damage, and promote remyelination.

Minocycline has been shown to reduce stroke infarct penumbra size and improve outcomes in functional recovery from stroke.1,2 Minocycline’s effects as a potent CNS anti-inflammatory and antiapoptotic agent are well established.

Clemastine has been shown to improve function in multiple sclerosis by activating oligodendrocyte precursor cells into active agents of myelination and fiber bundle stabilization.3 Clemastine reverses acute leukoencephalopathy.4

If we are to treat acute psychosis as a neurologic emergency, we cannot rely on long-acting injectable antipsychotics as the sole treatment. Psychiatric medication alone is not sufficient across every neuropsychiatric condition in which inflammation and white matter damage are part of the etiology, destruction, and pattern of relapse.

The adverse effects risk of adjunctive minocycline and clemastine is low compared with the potential benefits of stopping inflammation, reducing apoptosis, and jump-starting white matter repair. Doses of oral minocycline in the 50- to 100-mg/d range and oral clemastine in the 1.34- to 2.68-mg/d range together can lead to reduced cranial heat, improved cranial suture mobility, and improved elasticity of white matter bundle tracts palpable on physical examination. Both medications show clinical results in improved emotional self-regulation, according to family reports and clinical observations in the outpatient setting. There is no reason to delay neurologic-based adjunctive treatment when our goal is to prevent and reverse brain damage.
