A common clinical question in stroke prevention:
Patient with AF on DOAC presents with lacunar or ICAD related stroke
đ Should we keep him on đšđźđťđ´-đđ˛đżđş dual therapy for better prevention?
Recent clinical trials from both cardiology and neurology now give us clearer guidance:
⸝
đđ˛đ đżđ˛đ°đ˛đťđ đđżđśđŽđšđ:
đš đđ§đđŚ-đĄđŠđđ (JAMA Neurology 2025)
AF + non-cardioembolic stroke (atherothrombotic, lacunar, ICAD)
âĄď¸ DOAC alone is better than DOAC + antiplatelet
⢠Bleeding risk more than doubled with dual therapy (19% vs 8.6%)
đš đđŁđđ-đđđ (NEJM 2024)
AF + stable CAD
âĄď¸ Edoxaban monotherapy was safer than Edoxaban + single antiplatelet
⢠Lower net adverse clinical events with monotherapy
⢠Major bleeding significantly reduced (4.7% vs 14.2%)
đš đđ¤đ¨đđ§đđ (NEJM 2024)
AF + stable CAD
âĄď¸ Anticoagulation alone was safer (trial stopped early due to higher bleeding with dual)
⢠Major bleeding markedly increased (10.2% vs 3.4%) with dual therapy
đš Parallel cardiology evidence (AFIRE, AUGUSTUS, others)
Consistent message: once coronary disease is stable, anticoagulation alone is safer.
đđźđťđ´-đđ˛đżđş đđđŽđš đđťđđśđđľđżđźđşđŻđźđđśđ°đ = đŽâđŻĂ đĽđśđđ¸ đźđł đ đŽđˇđźđż đđšđ˛đ˛đąđśđťđ´
⸝
đđşđ˝đźđżđđŽđťđ đ°đšđśđťđśđ°đŽđš đ°đźđťđđ˛đ đ:
đ¸ đŚđľđźđżđ-đđ˛đżđş dual therapy is be appropriate for:
⢠Recent stent (cardiac, carotid, intracranial), Acute coronary syndrome
⢠Highly selected cases with acute ICAD-related stroke and concurrent AF (individualized, time-limited)
đ¸ For đđźđťđ´-đđ˛đżđş, evidence increasingly supports moving away from chronic antiplatelet + anticoagulation, because of markedly increased bleeding risk.
⸝
đđźđđđźđş đšđśđťđ˛:
â ď¸ Chronic dual antithrombotic therapy (anti-platelet + anticoagulation) â or prolonged DAPT â should be avoided unless there is a strong, clearly documented indication.
Thoughtful de-escalation is often the safest strategy for both brain and heart.

The debate around asymptomatic ICA stenosis continues, from ECST2 to CREST2.
đŚđđđąđ đŻđźđđđźđş đšđśđťđ˛:
In patients with asymptomatic ICA stenosis âĽ70%, 4-year stroke risk was đŽ.đ´% with stenting + intensive medical therapy vs đ˛.đŹ% with medical therapy alone â an absolute risk reduction of ~0.8% per year.
CEA did not show a statistically significant benefit over medical therapy alone in this population.

đ§đľđ˛ đŽđťđđđ˛đż đśđ: đĄđź, đťđźđ đ˛đđ˛đżđ đźđťđ˛
đđ˛đ đ°đŽđđ˛đŽđđ:
1ď¸âŁÂ đĄđĄđ§ đśđ đŻđ.
We need to treat 31 asymptomatic patients with stenting to prevent 1 stroke over 4 years. Thatâs a modest effect size.

Periprocedural stroke rate was đ.đŻ% for stenting â lower than what many centers report. This was achieved with:
- Strict operator credentialing and training, and
- Ongoing site monitoring; centers with rising complication rates were reviewed and could be restricted.
3ď¸âŁÂ đđźđ°đŽđš đ°đźđşđ˝đšđśđ°đŽđđśđźđť đżđŽđđ˛đ đşđŽđđđ˛đż.
If your institutionâs periprocedural stroke rate âđŻ%, the small absolute benefit is essentially washed out.
If itâs >đ°%, you may be causing net harm in asymptomatic patients.
4ď¸âŁ đ đ˛đąđśđ°đŽđš đşđŽđťđŽđ´đ˛đşđ˛đťđ đľđŽđ đśđşđ˝đżđźđđ˛đą.
In ACAS (1990s), the 5-year ipsilateral stroke risk on medical therapy was â11%.
In CREST-2, with modern intensive therapy, the 4-year risk fell to â6%.
5ď¸âŁÂ đđđđşđ˝đđźđşđŽđđśđ° â đđđşđ˝đđźđşđŽđđśđ°.
Not all asymptomatic disease pose very high stroke risk like symptomatic ones.
Without intervention, stroke risk in NASCET (symptomatic âĽ70%) was 26% over 2 years, compared to 11% over 5 years in ACAS/ACST (asymptomatic âĽ60%) in the same era.

When we teach the neurological exam, few things capture learnersâ attention like đżđ˛đłđšđ˛đ đ˛đ â and none more so than the đ˝đšđŽđťđđŽđż đżđ˛đđ˝đźđťđđ˛.
The story of the đđŽđŻđśđťđđ¸đś đđśđ´đťÂ â and the many ways it can be elicited â always fascinates students.
In the late 19th century, neurologists struggled to differentiate organic paralysis from functional or hysterical weakness.There were no MRIs, no labs â only the exam.
đđŽđŻđśđťđđ¸đś noticed something curious in 1896 while examining a patient with hemiplegia:
đ Stroking the sole of the foot caused the big toe to extend upward rather than flex downward â a pattern consistent across patients with corticospinal tract lesions.
đĄÂ đĽđ˛đđźđšđđđśđźđťđŽđżđ: A single reflex that spoke for the integrity of the entire corticospinal tract.
A few years later, his student Oppenheim described a variant of the same reflex. Over time, many others followed â each variant earning its own eponym.

A new NeurologyÂŽ Open Access study found that people with both gum disease and cavities had an 86% higher risk of stroke compared with those with healthy mouths.
𩸠Poor oral health was also linked to a 36% higher risk of heart attacks and other cardiovascular events.
𦷠Regular dental visits were associated with 81% lower odds of having both gum disease and cavities.
But hereâs the real question:
Is oral inflammation causing vascular disease â or do people who neglect oral care tend to neglect other aspects of health as well?
