Frequently Asked Questions (FAQs)

A lacunar stroke is a small, deep brain infarct—usually less than 15 mm across—that occurs when one of the brain’s tiny “penetrating” arteries becomes blocked. Because these vessels dive straight through the brain without detours, there are no back-up routes; when the vessel clogs, the patch of brain it feeds is instantly starved of oxygen and dies, leaving a microscopic cavity or “lacune.” Lacunar strokes account for roughly one quarter of all ischaemic strokes and are especially common in people with long-standing high blood pressure, diabetes, or other “small-vessel” disease. They strike hidden hubs such as the internal capsule, thalamus, basal ganglia and pons, so they rarely produce the flashy “cortical” signs (aphasia, visual field loss, neglect) that accompany large-artery strokes. Instead, they cause focused motor or sensory problems that can fool clinicians into thinking the event is mild—yet multiple silent lacunes can quietly add up to disability, gait trouble and vascular dementia in later life. Pathologically, two processes dominate: lipohyalinosis (the vessel wall thickens and degenerates under the hammer of high blood pressure) and micro-atheroma (miniature “plaques” form at the mouth of the perforating artery) ncbi.nlm.nih.gov.

A lacunar stroke is a tiny, deep brain infarct—usually <15 mm across—caused by blockage in one of the brain’s minute penetrating arteries. Because these vessels sit in the internal capsule, thalamus, basal ganglia, or pons, a clot can wipe out a “core” of fibres that carry signals between the cortex and the body. Classic “lacunar syndromes” include pure motor hemiparesis, ataxic hemiparesis, dysarthria–clumsy-hand syndrome, pure sensory loss, and mixed sensorimotor stroke. Unlike large-artery strokes, there is no major cortical sign such as aphasia or neglect, yet disability can still be profound. Hypertension, diabetes, aging, and smoking slowly scar these tiny arteries (lipohyalinosis), setting the stage for clot formation. ncbi.nlm.nih.gov

Classic Lacunar Stroke Types

Pure Motor Hemiparesis – Sudden weakness of face, arm and leg on one side, with no sensory loss, language change or vision problem. It is the commonest lacunar syndrome, representing up to half of cases and typically arises from an infarct in the posterior limb of the internal capsule, corona radiata or basis pontis wjgnet.com.
Pure Sensory Stroke – Numbness, tingling, burning or loss of touch/pain/temperature down one side of the body, face or limbs. The culprit lesion is usually in the ventral (posterolateral) thalamus ncbi.nlm.nih.gov.
Ataxic-Hemiparesis – A curious blend of clumsiness/ataxia and mild weakness in the same limbs. It points to damage in the internal capsule, corona radiata or dorsal pons, where motor and cerebellar pathways run side-by-side.
Dysarthria–Clumsy Hand Syndrome – Slurred speech paired with awkward, slow fine movements of the contralateral hand; the lesion often sits in the genu of the internal capsule or basis pontis.
Sensorimotor Stroke – Combined weakness and sensory loss on the same side; it reflects a slightly larger infarct straddling the thalamus and adjacent internal capsule.
Pure Dysarthria – Isolated slurring without limb weakness when a lacune clips the corticobulbar tract in the pons.
Isolated Hemichorea or Athetoid Hand – Abrupt involuntary movements when a small lesion irritates basal ganglia output loops.
Palatal Myoclonus – Rhythmic soft-palate jerks after a tiny stroke in the dentatolivary pathway of the brainstem.
Facial Weakness with Dysarthria – A pinpoint capsular or pontine infarct affecting only face and speech fibres.
Pure Hemianesthesia – Loss of all modalities of sensation sparing pain, suggesting a posterolateral thalamic lacune.

Each type is a “clinical fingerprint” that helps doctors suspect an LSS even before the scan.

Non-Pharmacological Treatments

Below are thirty therapies grouped into (A) physiotherapy/electrotherapy, (B) exercise-focused, (C) mind-body & self-management. Each paragraph explains what it is, why it is used, and how it works.

A. Physiotherapy & Electrotherapy

Task-Oriented Motor Relearning – Re-practising everyday tasks (pouring water, buttoning a shirt) rewires spared motor pathways through “use-dependent plasticity,” speeding functional independence.
Constraint-Induced Movement Therapy (CIMT) – Temporarily immobilising the strong limb forces use of the weak side for 6 h/day, strengthening neglected neural circuits and shrinking learned non-use.
Bobath Neuro-Developmental Technique – Hands-on guidance helps patients sense correct posture and movement, damping spastic synergy and promoting normal patterns.
Proprioceptive Neuromuscular Facilitation (PNF) – Spiral and diagonal stretching with manual resistance heightens muscle spindle input, making dormant corticospinal tracts fire more efficiently.

Transcutaneous Electrical Nerve Stimulation (TENS) – Low-level sensory currents placed near the spine reduce central pain and may prime cortical areas before exercise, improving tolerance.
Neuromuscular Electrical Stimulation (NMES) – Stronger currents than TENS contract paretic muscles repeatedly, preventing atrophy while supraspinal tracts recover.
High-Intensity Interval Treadmill Training – Alternating fast bursts with slow walking pushes cardiorespiratory fitness safely, doubling gait speed gains versus usual care. healthquality.va.gov
Robotic Over-Ground Gait Trainers – Wearable exoskeletons guide hip-knee-ankle motion, delivering thousands of perfect steps that the therapist’s hands cannot replicate.
Aquatic Therapy – Warm water’s buoyancy off-loads weak limbs, letting patients practise standing balance and reach earlier than on land.
Repetitive Transcranial Magnetic Stimulation (rTMS) – Magnetic pulses over the unaffected motor cortex suppress maladaptive inhibition, unmasking circuits in the affected hemisphere.
Low-Level Laser Therapy (LLLT) – Near-infra-red light penetrates scalp to boost mitochondrial ATP in ischemic penumbra, theoretically accelerating repair.
Mirror Therapy – Watching the good limb’s reflection tricks mirror neurons, awakening sensory–motor maps linked to the paretic side.
Postural Biofeedback Training – Force-plate or vest sensors beep when centre of mass drifts, teaching mid-line control and fall prevention.
Sensory Re-education with Vibration – High-frequency vibration recruits wide-dynamic-range neurons, sharpening touch localisation after pure sensory lacunar infarct.

Yoga – Poses plus diaphragmatic breathing stretch spastic muscles and lower cortisol, easing anxiety common after stroke.
Pilates Mat Work – Core-centric exercises stabilise lumbar–pelvic control, translating to steadier gait.
Progressive Resistive Exercise (PRE) – Graduated weights fight disuse atrophy; studies show up to 30 % strength gain without raising spasticity.
Nordic Walking – Poles spread load to upper limbs, allowing longer distances and higher VO₂-max gains.

C. Mind-Body & Educational Self-Management

Mindfulness-Based Stress Reduction (MBSR) – Eight-week course blends meditation and mindful walking; fMRI shows thicker anterior cingulate and calmer amygdala activity, linked to better mood and cognition after stroke. pmc.ncbi.nlm.nih.govpubs.asha.orgpmc.ncbi.nlm.nih.gov
Guided Imagery & Box Breathing – Visualising smooth limb movement while inhaling 4-hold 4-exhale 4 reduces autonomic arousal and primes cortical excitability.

Cognitive-Behavioural Stroke Self-Management – Six-session programme teaches goal-setting, problem-solving, and medication adherence, halving rehospitalisation.
Peer-Led Support Groups – Listening to survivors and caregivers normalises emotional swings, boosting retention in therapy.
Tele-Rehab Home Exercise Monitoring – Secure video plus wearable sensors keep patients accountable between visits and expand access in rural areas.

Drugs for Lacunar Stroke Care

Below, each medication is explained in plain English with dose, class, timing, and typical side effects. Always follow your own doctor’s instructions.

Aspirin 81–325 mg once daily – An antiplatelet that keeps sticky platelets from clumping on damaged small arteries. Early (within 24 h) use cuts recurrence 15 %. Biggest risks: upset stomach and rare gut bleeding. pmc.ncbi.nlm.nih.gov
Clopidogrel 75 mg daily – A P2Y12 blocker; often swapped in if aspirin intolerance or combined short-term (21 days) with aspirin for extra protection. Watch for bruising and, rarely, low white-cell count. pmc.ncbi.nlm.nih.govahajournals.org
Ticagrelor 90 mg twice daily – Faster, reversible P2Y12 blocker helpful when genetic tests show clopidogrel resistance. Side effects: dyspnoea and nosebleeds. pmc.ncbi.nlm.nih.gov
Cilostazol 100 mg twice daily – Antiplatelet + vasodilator; Asian trials show fewer brain haemorrhages versus aspirin but minor headaches and palpitations.
Aspirin + Dipyridamole (200/25 mg, bid extended-release) – Dual mechanism: platelet blockade plus arterial vasodilation; may cause pounding headaches initially.
Atorvastatin 40–80 mg nightly – High-intensity statin shrinks cholesterol plaques and dampens inflammation; monitor liver enzymes and muscle aches.
Rosuvastatin 20 mg nightly – Alternative potent statin with stronger LDL drop for some; can slightly raise blood sugar.
Lisinopril 10–40 mg daily – ACE inhibitor first-line for hypertension; lowers recurrent stroke by ~28 %. Dry cough is common, severe dizziness rare.
Amlodipine 5–10 mg daily – Long-acting calcium-channel blocker; gentle on kidneys and effective in Black and older adults; watch ankle swelling.
Indapamide 1.5 mg sustained-release daily – Thiazide-like diuretic favoured in lacunar stroke studies; may drop potassium.
Hydrochlorothiazide 25 mg morning – Cheaper diuretic; combine with ACE inhibitor for synergy.
Perindopril 4–8 mg daily – ACE inhibitor used in the PROGRESS trial that cut recurrence 43 % when paired with indapamide.
Ticlopidine 250 mg twice daily – Older P2Y12 blocker; seldom used owing to risk of neutropenia and liver toxicity but option if others fail.
Apixaban 5 mg twice daily – DOAC for patients who also have atrial fibrillation; sidesteps warfarin’s lab checks. Bruising and rare GI bleeding possible.
Dabigatran 150 mg twice daily – Another DOAC; acid-buffered capsule may cause dyspepsia.
Rivaroxaban 20 mg with supper – Once-daily DOAC; needs good kidney function.
Nicardipine IV infusion (5 mg/h up‐titrated) – Used acutely to lower dangerously high BP in the emergency window; headache and reflex tachycardia possible.
Alteplase (tPA) 0.9 mg/kg IV over 60 min – Clot-buster licensed up to 4.5 h from onset; risk is brain bleeding but chance of full recovery doubles.
Tenecteplase 0.25 mg/kg single IV push – Easier bolus alternative to tPA with similar efficacy; not yet universal standard.
Edoxaban 60 mg daily – DOAC with low intracranial bleed rate; dose-reduce if kidney function is low.

Dietary Molecular Supplements

Always clear any supplement with your neurologist—some interact with antiplatelet drugs.

Omega-3 Fish Oil (EPA + DHA 1 g/day) – Thins blood slightly, lowers inflammation, and supports neuronal membrane repair.
Vitamin D3 (1,000–2,000 IU/day) – Low levels link to bigger stroke size; supplementation modulates calcium channels and immune tone.
Coenzyme Q10 (100 mg twice daily) – Mitochondrial co-factor that scavenges free radicals, potentially improving post-stroke fatigue.
Magnesium Citrate (300 mg elemental nightly) – Supports NMDA receptor modulation, reducing excitotoxicity and muscle cramps.

Umbilical Wharton’s Jelly MSCs (2 × 10⁶ cells/kg intra-arterial) – Under investigation for chronic lacunar deficits; early data show motor-score gains but risk of micro-emboli unknown.
Exosome-Enriched Plasma Infusion (once monthly) – Nano-vesicles loaded with miRNA may cross BBB and nudge synaptogenesis.
Recombinant Nerve Growth Factor Gene Therapy (single intrathecal injection) – Viral vector delivers NGF gene to cerebrospinal fluid, aiming to awaken dormant circuits.
Platelet-Rich Plasma (PRP 5 mL intramuscular to spastic limbs) – Autologous growth factors hope to soften spasticity; evidence still preliminary.

Surgical or Interventional Procedures

Mechanical Thrombectomy – A stent-retriever pulls out clots in proximal arteries; rarely needed for true lacunes but vital for tandem large-artery stroke.
Carotid Endarterectomy – Surgical plaque removal in >70 % carotid stenosis prevents future emboli, indirectly cutting lacunar-plus-large-vessel stroke risk.
Carotid Artery Stenting – Less invasive option when anatomy or health precludes open surgery.
Extracranial–Intracranial (EC–IC) Bypass – Connects scalp artery to a cortical branch, augmenting deep perfusion when multiple lacunes drain reserve.
Decompressive Hemicraniectomy – Removes part of skull after malignant swelling; life-saving in massive infarcts.
Ventriculostomy – Catheter into ventricles to relieve hydrocephalus after pontine lacunar bleed.
Deep Brain Stimulation (DBS) for Thalamic Pain – Electrodes in periventricular grey may ease intractable central post-stroke pain.

Get annual medical reviews—even if you feel “fine.”

When Should You See a Doctor?

Immediately call emergency services if you or a loved one notice sudden numbness or weakness of face/arm/leg, difficulty speaking, loss of balance, or a thunderclap headache. After discharge, return sooner than scheduled if you develop chest pain, irregular pulse, black stools, lingering double vision, or new limb swelling.

Things to Do—and Ten to Avoid

Do:

Take medicines exactly as prescribed.
Check blood pressure at home twice daily.
Keep moving—stand every hour.
Practise home exercises.
Eat colourful vegetables.
Use a pill organiser.
Join a support group.
Wear sturdy footwear.
Schedule dental care (mouth bacteria raise stroke risk).
Celebrate small wins to stay motivated.

Avoid:

Skipping doses to “save money.”
Crash diets that sap muscle.
Dehydration—thickens blood.
Smoking “just one” cigarette.
Excess NSAIDs (they increase bleed risk).
Unproven herbal cocktails that thin blood.
High-heeled or backless shoes during recovery.
Driving before your doctor clears you.
Heavy lifting in first three months.
Neglecting mental health—depression is common but treatable.

Frequently Asked Questions (FAQs)

Can a lacunar stroke be completely cured?
Some people regain full independence, especially with early rehab, but tiny scars usually persist on MRI.
Why did my stroke happen at night?
Blood pressure dips and platelet “stickiness” spike around dawn, raising clot risk.
Is aspirin enough, or do I need dual therapy forever?
Dual antiplatelets are useful only for the first 21–90 days; after that, aspirin or clopidogrel alone is safer. pmc.ncbi.nlm.nih.gov
Will I inherit lacunar strokes from my parents?
Genetics play a modest role; lifestyle factors such as hypertension matter far more.
Does every lacune cause symptoms?
No—up to 25 % are “silent” and found incidentally but still raise dementia risk over time.
Is stem-cell therapy available outside trials?
Not yet; clinics selling unregulated cells should be avoided. pmc.ncbi.nlm.nih.gov
Can I fly after a stroke?
Usually after 2 weeks if stable, but wear compression socks and move hourly.
Do statins really work if my cholesterol is normal?
Yes—statins also calm artery inflammation, a key trigger in lacunar disease.
Why am I so tired months later?
Post-stroke fatigue stems from brain-energy imbalance; graded exercise and sleep hygiene help.
Can coffee trigger another stroke?
Moderate coffee (≤3 cups) is safe; unfiltered “boiled” coffee can raise cholesterol.
Is dizziness always a sign of another stroke?
Not necessarily—inner-ear issues are common, but sudden severe dizziness with imbalance warrants ER evaluation.
Will sex increase my blood pressure too much?
Sexual activity equals climbing two flights of stairs; if you can do that safely, sex is usually fine.
What’s the best diet—keto, vegan, or Mediterranean?
Mediterranean has the strongest stroke-prevention evidence thanks to healthy fats and polyphenols.
Could my smartwatch detect stroke?
It may pick up atrial fibrillation but cannot detect clots; still call emergency services if you have symptoms.
How long should I stay on blood thinners?
For lacunar stroke without atrial fibrillation, antiplatelet therapy is lifelong unless bleeding risk becomes prohibitive.
