A stroke, known as a stroke, interrupts blood flow to the brain and requires immediate action to minimize damage. Health professionals warn that quickly recognizing symptoms can double the chances of complete recovery. In Brazil, the problem affects thousands of people annually, with peaks in urban centers.
Symptoms appear abruptly, affecting motor and cognitive functions. Doctors recommend using the acronym SAMU for initial assessment: Smile, Hug, Message and Urgency. This simple tool helps laypeople identify the condition in minutes.
Recent data indicate that care within four and a half hours after the onset of signs improves the prognosis. Hospitals equipped with tomography and thrombolytic medications are essential during this period.
SAMU method for quick detection
The acronym SAMU makes it easier to check symptoms in any situation. It guides basic observations that anyone can make.
First, ask the person to smile and notice whether one side of the face drops. This asymmetry indicates possible vascular obstruction.
Then ask him to raise both arms. If one of them falls or does not rise, the sign reinforces the suspicion of a stroke.
Changes in speech and vision require verification
Difficulty speaking arises when brain areas responsible for language are affected. The person may slur words or not understand simple instructions.
This change occurs in up to 70% of ischemic stroke cases. Test by asking you to repeat a short phrase, such as “the sky is blue.”
Visual problems affect one or both eyes, with blurred vision or sudden loss. This sensory failure requires immediate checking, as it signals an interruption in the blood supply.
Dizziness often accompanies, causing disorientation. Record the exact start time to inform emergency services.
Stroke types and initial responses
Ischemic stroke results from a clot blocking cerebral arteries, representing 85% of cases. Hemorrhagic involves rupture of vessels, with internal bleeding.
Both require quick transport to a specialized unit. Call 911 and describe the symptoms you observed.
Do not give food or medicine to the victim. Keep her in a lateral position if vomiting occurs to avoid aspiration.
Exams such as tomography confirm the type and guide treatment. Thrombectomy removes clots within 24 hours, but the ideal is to act within the first six.
Factors that increase the risk of occurrence
High blood pressure affects more than 30% of the Brazilian adult population and multiplies the risk of stroke by five. Regular pressure control prevents blockages.
Diabetes and high cholesterol contribute to the formation of plaque in the arteries. Annual monitoring detects these conditions early.
Smoking damages blood vessels, increasing the incidence in active smokers. Cessation reduces risk by 50% after one year.
Obesity and a sedentary lifestyle worsen the situation in young people, with cases rising 20% in the last decade. Moderate physical activity three times a week mitigates these factors.
Essential hospital procedures
In the emergency room, the team stabilizes the patient with oxygen and glycemic control. Medications dissolve clots in short windows of time.
Rehabilitation begins soon after, with physiotherapy for mobility. Speech therapy assists in the recovery of affected speech.
Occupational therapy restores daily tasks such as getting dressed. Multidisciplinarity accelerates independence in 60% of cases.
Less common signs not to ignore
Intense headache with no previous cause may indicate hemorrhage. This complaint appears in 40% of hemorrhagic strokes and requires immediate imaging.
Mental confusion frequently affects elderly people, simulating fatigue. Assess whether the person recognizes themilitary or the location.
Difficulty swallowing increases the risk of pneumonia. Test with a sip of water; failure indicates need for nutritional support.
Seizures occur in 5% of initial episodes. Protect your head and call for help without restricting movement.
Immediate action saves brain functions
Every minute without treatment destroys around 2 million neurons. Early help preserves memory and motor coordination.
Stroke units in the SUS provide free care, with standardized protocols. Download apps like AVC Brasil to locate nearby centers.
Families should discuss emergency plans with seniors. Basic first aid training multiplies the effectiveness of the response.
