Stroke Warning Signs
Stroke is a medical emergency where every minute counts. Recognizing the warning signs using the BE FAST method can save a life and reduce long-term disability at Palamu Neuro & Eye Care, serving Medininagar and Jharkhand.
Understanding Stroke: A Brain Attack
A stroke, often called a brain attack, occurs when blood supply to a part of the brain is interrupted or severely reduced, depriving brain tissue of oxygen and nutrients. Within minutes, brain cells begin to die, and with each passing minute, approximately 1.9 million neurons, 14 billion synapses, and 12 kilometers of myelinated fibers are lost.
There are two major types of stroke. Ischemic stroke, accounting for approximately 87 percent of all strokes, occurs when a blood clot blocks a cerebral artery, either from a thrombus formed at the site of an atherosclerotic plaque in a cerebral or carotid artery, or from an embolus originating in the heart in conditions such as atrial fibrillation or from an atherosclerotic plaque in the aortic arch or carotid artery.
Hemorrhagic stroke accounts for about 13 percent of strokes but a disproportionately higher share of mortality, and occurs when a weakened blood vessel ruptures, bleeding into the brain parenchyma (intracerebral hemorrhage) or into the subarachnoid space surrounding the brain (subarachnoid hemorrhage). Intracerebral hemorrhage is most commonly caused by chronic hypertension damaging small penetrating arteries, while subarachnoid hemorrhage is most frequently caused by rupture of a cerebral aneurysm.
A transient ischemic attack, or TIA, is a temporary blockage that produces stroke symptoms lasting less than 24 hours, usually minutes to an hour, without causing permanent brain infarction. A TIA is a critical warning sign, as approximately 10 to 15 percent of patients with a TIA will experience a full stroke within 90 days, with half of those occurring within the first 48 hours.

The BE FAST Acronym: Recognizing Stroke Symptoms
The BE FAST acronym is a simple, memorable tool for recognizing the most common signs of stroke and emphasizes the urgency of timely action. At Palamu Neuro & Eye Care, our specialists are committed to delivering this high standard of care locally in Medininagar.
B — Balance
Sudden loss of balance or coordination, difficulty walking, dizziness, or a sense of the room spinning.
E — Eyesight
Sudden vision changes including blurred vision, double vision, or loss of vision in one or both eyes, which may result from involvement of the occipital lobe, brainstem, or optic pathways.
F — Face
Ask the person to smile and observe whether one side of the face droops or feels numb; facial asymmetry is a hallmark of stroke affecting the motor cortex or facial nerve pathways.
A — Arm
Ask the person to raise both arms and check whether one arm drifts downward or cannot be raised at all, indicating unilateral motor weakness.
S — Speech
Ask the person to repeat a simple sentence and listen for slurred speech, inability to find words, or incomprehensible speech, reflecting involvement of language centers in the dominant hemisphere.
T — Time
If any of these signs are present, even if they resolve quickly, call emergency services immediately; note the time when symptoms first appeared because it determines eligibility for time-sensitive treatments.
Beyond BE FAST, other stroke symptoms include sudden severe headache with no known cause, which may indicate subarachnoid hemorrhage; sudden confusion or altered mental status; and sudden numbness or weakness of the leg as well. The key principle is that stroke symptoms are acute in onset and typically affect one side of the body. At Palamu Neuro & Eye Care, our specialists are committed to delivering this high standard of care locally in Medininagar.
Time Is Brain: The Critical Treatment Window
The principle that time is brain underscores the urgency of stroke treatment. Intravenous thrombolysis with alteplase, a recombinant tissue plasminogen activator that dissolves clots, is the cornerstone of acute ischemic stroke therapy but is only approved for administration within 4.5 hours of symptom onset, and its effectiveness declines sharply with time.
After 4.5 hours and up to 24 hours, selected patients may still benefit from mechanical thrombectomy, a procedure in which an interventional neuroradiologist or neurosurgeon threads a catheter from the groin or wrist to the occluded cerebral artery and retrieves or aspirates the clot, restoring blood flow. The therapeutic window for thrombectomy extends to 24 hours in carefully selected patients with a small core infarct and significant salvageable penumbra identified by advanced CT perfusion or MRI diffusion-perfusion imaging.
For hemorrhagic stroke, treatment focuses on controlling blood pressure, reversing any coagulopathy, managing intracranial pressure, and in selected cases, surgical evacuation of the hematoma or clipping or coiling of a ruptured aneurysm. Every minute of delay in restoring blood flow or controlling hemorrhage translates into greater brain tissue loss and worse functional outcomes. This is why stroke is always a 108 emergency and why one should never wait at home to see if symptoms resolve. At Palamu Neuro & Eye Care, our specialists are committed to delivering this high standard of care locally in Medininagar.
Golden Hour Principle
The number needed to treat for a favorable outcome with alteplase is approximately 5 within the first 90 minutes, 9 within 91 to 180 minutes, and 14 within 181 to 270 minutes. Dr. Yuvraj Lahre emphasizes that patients arriving at the hospital within the golden hour have the best chance of returning to independent life.
Risk Factors and Prevention Strategies
The majority of strokes are preventable through identification and management of modifiable risk factors. Hypertension is the single most important modifiable risk factor, present in approximately 70 percent of first stroke patients, and lowering systolic blood pressure by even 10 mmHg reduces stroke risk by approximately one-third. At Palamu Neuro & Eye Care, our specialists are committed to delivering this high standard of care locally in Medininagar.
- In Palamu: Atrial fibrillation increases stroke risk fivefold by allowing blood to stagnate and form clots in the left atrial appendage; anticoagulation reduces this risk by 60 to 70 percent.
- Diabetes mellitus accelerates atherosclerosis and increases stroke risk two to fourfold; maintaining hemoglobin A1c below 7 percent is the recommended target for most patients.
- Dyslipidemia, particularly elevated LDL cholesterol, contributes to atherosclerotic plaque formation; statin therapy reduces first stroke risk by approximately 25 percent.
- Smoking doubles the risk of ischemic stroke, and cessation reduces risk to near that of nonsmokers within five years.
- Physical inactivity, obesity, and diets high in sodium and low in fruits and vegetables are independent risk factors.
- Excessive alcohol consumption increases both ischemic and hemorrhagic stroke risk.
- Carotid artery stenosis, prior TIA or stroke, sickle cell disease, and certain autoimmune conditions causing vasculitis.
Comprehensive stroke prevention involves a combination of pharmacological management of vascular risk factors, antiplatelet or anticoagulant therapy where indicated, and aggressive lifestyle modification. At Palamu Neuro & Eye Care, our specialists are committed to delivering this high standard of care locally in Medininagar.
What to Do While Waiting for Emergency Services
If you suspect someone is having a stroke, call 108 immediately. Do not drive the person to the hospital yourself unless there is absolutely no alternative, as paramedics can begin assessment, provide basic life support, and alert the receiving hospital's stroke team to prepare for your arrival, significantly reducing door-to-needle time. At Palamu Neuro & Eye Care, our specialists are committed to delivering this high standard of care locally in Medininagar.
- 1
Note the exact time
Record when symptoms began or when the person was last seen normal — this is critical information the emergency team will need.
- 2
Position the person safely
Lay the person flat with the head and shoulders slightly elevated on a pillow if possible. If unconscious, place them in the recovery position on their side to maintain an open airway and allow secretions to drain.
- 3
Do not give food or drink
Do not give the person anything to eat or drink, as stroke can impair swallowing and increase the risk of aspiration.
- 4
Do not administer medication
Do not administer aspirin or any other medication unless specifically instructed by emergency medical personnel — if the stroke is hemorrhagic rather than ischemic, aspirin can worsen bleeding.
- 5
Loosen tight clothing
Loosen any tight clothing around the neck and chest to facilitate breathing.
- 6
Stay calm and monitor
Speak reassuringly and provide comfort while continuously monitoring consciousness and breathing. If the person stops breathing and you are trained in CPR, begin chest compressions.

Frequently Asked Questions
Can stroke symptoms come and go, and does that mean the danger is over?
Transient stroke symptoms that resolve completely are known as a transient ischemic attack or TIA, and they are a medical emergency, not a sign that the danger has passed. A TIA is a critical warning that a full stroke may be imminent, with approximately 10 to 15 percent of patients experiencing a stroke within 90 days, half of which occur within the first 48 hours. The ABCD2 score, which considers age, blood pressure, clinical features, duration of symptoms, and presence of diabetes, helps stratify the short-term stroke risk. Even when symptoms resolve, a TIA demands urgent neurological evaluation including brain imaging, vascular imaging of the carotid and vertebral arteries, cardiac evaluation for atrial fibrillation and other embolic sources, and comprehensive risk factor assessment. Dr. Yuvraj Lahre strongly advises against the common mistake of dismissing resolved symptoms and recommends immediate evaluation at Palamu Neuro & Eye Care or an emergency department.
Are strokes only a problem for older people?
While advancing age is the strongest non-modifiable risk factor, with stroke risk doubling for each decade after age 55, strokes can and do occur in young adults and even children. Approximately 10 to 15 percent of all strokes occur in adults aged 18 to 50, and the incidence of ischemic stroke in younger adults has been rising, partly attributable to increasing rates of obesity, diabetes, hypertension, and substance use in this age group. Causes of stroke in young adults differ from those in the elderly and more often include arterial dissection from trauma or neck manipulation, cardioembolism from undiagnosed structural heart defects such as patent foramen ovale, hypercoagulable states, vasculitis, moyamoya disease, and recreational drug use including cocaine and amphetamines. The key message is that age does not exclude stroke, and a sudden onset of focal neurological symptoms in a young person should be evaluated with the same urgency as in an older adult. Dr. Yuvraj Lahre at Palamu Neuro & Eye Care has extensive experience evaluating and managing stroke across all age groups.
Can you recover fully after a stroke?
Recovery after stroke depends on multiple factors including the size and location of the infarct or hemorrhage, the patient's age and premorbid health, the promptness of acute treatment, and the intensity of rehabilitation. With timely thrombolysis or thrombectomy and comprehensive rehabilitation, many patients achieve excellent recovery, with approximately 10 percent recovering almost completely and another 25 percent recovering with only minor impairments. However, stroke remains a leading cause of serious long-term disability, with about 40 percent of survivors left with moderate to severe impairments. The brain exhibits neuroplasticity, the ability of surviving neurons to form new connections and reorganize functional networks, which is the basis for recovery. This plasticity is most active in the first 3 to 6 months post-stroke, making early and intensive rehabilitation critical. Physical therapy restores motor function and gait, occupational therapy addresses activities of daily living, speech and language therapy targets aphasia and dysphagia, and cognitive rehabilitation addresses deficits in memory, attention, and executive function. Psychological support is essential given the high rates of post-stroke depression and anxiety. Dr. Yuvraj Lahre coordinates comprehensive post-stroke care at Palamu Neuro & Eye Care, addressing medical secondary prevention alongside rehabilitation needs.
What is the difference between ischemic and hemorrhagic stroke treatment?
The treatment approaches for ischemic and hemorrhagic stroke are fundamentally different, which is why a CT scan is always performed first in the emergency department to distinguish between them. Ischemic stroke treatment focuses on restoring blood flow: intravenous alteplase within 4.5 hours dissolves the clot, and mechanical thrombectomy retrieves large clots from major cerebral arteries within 24 hours in eligible patients. After the acute phase, antiplatelet therapy such as aspirin or clopidogrel is started to prevent recurrent ischemic events, along with management of vascular risk factors. For hemorrhagic stroke, the priority is controlling active bleeding rather than breaking up clots, and administering a thrombolytic or antiplatelet agent could be catastrophic. Treatment involves aggressive blood pressure reduction, reversal of any anticoagulant medications with specific reversal agents, management of elevated intracranial pressure through head elevation, hyperventilation, osmotic therapy with mannitol or hypertonic saline, and in selected cases, neurosurgical evacuation of the hematoma or decompressive craniectomy. For subarachnoid hemorrhage from a ruptured aneurysm, early surgical clipping or endovascular coiling of the aneurysm is essential to prevent catastrophic rebleeding, which carries a mortality exceeding 70 percent. Dr. Yuvraj Lahre emphasizes that the critical first step distinguishing ischemic from hemorrhagic stroke is why every suspected stroke must be evaluated in an emergency department without delay.
