Most stroke survivors have been capable of safely take two kinds of frequent antidepressants, in keeping with a preliminary research to be introduced on the American Stroke Affiliation’s Worldwide Stroke Convention 2024. The assembly can be held in Phoenix, Feb. 7-9, and is a world premier assembly for researchers and clinicians devoted to the science of stroke and mind well being.
Amongst individuals with ischemic (clot-caused) stroke, those that started taking an antidepressant generally known as an SSRI (selective serotonin reuptake inhibitor) and/or an SNRI (serotonin and norepinephrine reuptake inhibitor) for the frequent situations of post-stroke despair and anxiousness, didn’t have an elevated threat of hemorrhagic (bleeds) stroke or different critical bleeding. This included individuals taking anticoagulation drugs. There was, nonetheless, an elevated threat of hemorrhagic stroke amongst stroke sufferers taking two anti-platelet drugs, additionally known as twin anti-platelet remedy or DAPT.
Psychological well being situations, akin to despair and anxiousness, are quite common but treatable situations that will develop after a stroke. Our outcomes ought to reassure clinicians that for many stroke survivors, it’s protected to prescribe SSRI and/or SNRI antidepressants early after stroke to deal with post-stroke despair and anxiousness, which can assist optimize their sufferers’ restoration. Nevertheless, warning is required when contemplating the risk-benefit profile for stroke sufferers receiving twin anti-platelet remedy as a result of we did discover an elevated threat of bleeding amongst this group.”

In accordance with the American Coronary heart Affiliation’s Coronary heart Illness and Stroke Statistics 2024 Replace, when thought-about individually from different cardiovascular illnesses, stroke ranks fifth amongst all causes of dying, behind illnesses of the guts, most cancers, COVID-19 and unintentional accidents/accidents. Roughly one-third of stroke survivors develop poststroke despair. If left untreated, despair could have an effect on high quality of life and cut back the probabilities for optimum poststroke restoration akin to returning to their standard each day dwelling actions with out help.
The commonest courses of antidepressants are SSRIs or SNRIs, and they’re broadly used and efficient for treating anxiousness and despair. Nevertheless, they will not be prescribed in any respect or early sufficient after a stroke, when the chance of despair or anxiousness is especially excessive, resulting from considerations that they might enhance the chance of a hemorrhagic stroke or different critical kinds of bleeding.
Researchers seemed on the frequency of great bleeding amongst tons of of 1000’s of stroke survivors who took various kinds of SSRI and/or SNRI antidepressants (akin to sertraline, fluoxetine, citalopram, venlalfaxine). Critical bleeding was outlined as bleeding within the mind, digestive tract; and shock, which happens when bleeding prevents blood from reaching the physique’s tissues.
Researchers additionally investigated critical bleeding amongst stroke survivors who took antidepressants mixed with various kinds of blood-thinning drugs which are used to forestall future blood clots. These blood-thinning drugs could embrace both anticoagulants or antiplatelet drugs. Anticoagulants are prescribed as a single treatment and embrace drugs akin to warfarin, apixaban and rivaroxaban. Antiplatelet drugs could also be prescribed as both a single treatment (generally aspirin) or two kinds of antiplatelet drugs can be utilized in twin antiplatelet remedy. DAPT contains aspirin plus one other antiplatelet treatment known as a P2Y12 inhibitor (akin to clopidogrel, prasugrel or ticagrelor).
The research discovered:
- SSRI and SNRIs have been usually protected to start out throughout the essential early levels of restoration as sufferers taking these drugs weren’t extra prone to develop critical bleeding in comparison with stroke survivors who didn’t take an antidepressant. This included ischemic stroke sufferers who’re additionally taking anti-coagulation remedy.
- An elevated threat of great bleeding occurred when SSRIs or SNRIs have been taken together with DAPT remedies (aspirin and blood thinners). Nevertheless, the general threat remained low as critical bleeding occasions have been uncommon.
- Amongst ischemic stroke sufferers on antidepressant drugs, there was a 15% enhance within the threat of great bleeding when taking drugs from courses akin to mirtazapine, bupropion and tricyclics in comparison with SSRI/SNRIs.
“Maximizing rehabilitation early after a stroke is crucial as a result of restoration is considerably time-dependent, and most useful features happen throughout the first few months after a stroke,” Simmonds mentioned. “Luckily, twin antiplatelet remedy is usually administered for 14, 30 or 90 days, so, when indicated, clinicians could not must withhold antidepressant drugs for extended durations of time. Future analysis ought to examine the chance of bleeding related to the usage of anti-depressant and anxiousness drugs amongst sufferers with hemorrhagic or bleeding stroke.”
In accordance with a 2022 American Coronary heart Affiliation scientific assertion, social isolation and loneliness are related to a few 30% elevated threat of coronary heart assault or stroke, or dying from both. “Melancholy could result in social isolation, and social isolation could enhance the chance of experiencing despair. The present research helps reply questions of safety round the usage of antidepressants for remedy of psychological well being points that will develop after a stroke,” mentioned Crystal Wiley Cené, M.D., M.P.H., FAHA, chair of the writing group for the Affiliation’s scientific assertion, and a professor of scientific drugs and chief administrative officer for well being fairness, variety and inclusion on the College of California San Diego Well being. Dr. Cené was not concerned on this research.
Research particulars and design:
- The retrospective research included digital medical information information from 666,150 ischemic stroke sufferers from over 70 giant well being care facilities in america: 35,631 have been taking SSRI/SNRI antidepressant treatment, and 23,241 have been taking different antidepressants; nonetheless, most (607,278) weren’t taking any antidepressant.
- Sufferers have been handled at 70 well being care facilities over 20 years.
- Sufferers have been recognized from digital medical information for 2003 by means of 2023.
The research had some limitations. Researchers used statistical strategies to regulate for variations among the many teams that won’t have accounted for all of the essential variations among the many teams. The research additionally didn’t account for the dosage, period, or variety of antidepressants taken by individuals, which can have affected the outcomes.
