Clinical Features of Stroke & Management

By caringsurgeon | Published 8 December 2023 | No Comments

A stroke, also known as a cerebrovascular accident (CVA), occurs when there is a sudden disruption of blood flow to the brain, leading to damage to brain tissue. There are two main types of stroke: ischemic and hemorrhagic. The clinical features of a stroke can vary depending on the type and location of the brain affected. Here are common clinical features associated with stroke:

1. Sudden Onset of Symptoms: Strokes often have a rapid onset of symptoms, with little or no warning. The symptoms can develop within minutes.
2. F.A.S.T. Signs: The acronym F.A.S.T. is commonly used to recognize and respond to stroke symptoms:
   • Face Drooping: One side of the face may droop or become numb.
   • Arm Weakness: One arm may become weak or numb, and the person may have difficulty raising both arms.
   • Speech Difficulty: Speech may be slurred or difficult to understand.
   • Time to Call Emergency Services: Time is crucial in stroke treatment. It’s important to seek emergency medical attention immediately if any of these signs are observed.
3. Trouble Walking: A stroke can affect coordination and balance, leading to difficulty walking or a sudden loss of balance and coordination.
4. Severe Headache: A sudden, severe headache that is different from the usual headaches one might experience can be a symptom of a hemorrhagic stroke.
5. Vision Changes: Sudden vision changes, such as blurred or double vision, loss of vision in one eye, or difficulty seeing in one or both eyes, may occur.
6. Confusion or Disorientation: Stroke can cause confusion, difficulty understanding, or sudden memory loss.
7. Nausea and Vomiting: Some individuals may experience nausea or vomiting, particularly if the stroke affects the area of the brain responsible for coordination and balance.
8. Difficulty Swallowing: A stroke may affect the muscles used for swallowing, leading to difficulty swallowing.

It’s important to note that these symptoms may vary, and not all individuals will experience the same symptoms. Additionally, some strokes may be “silent” and not present with obvious symptoms, making regular medical check-ups important for early detection and prevention.

If you suspect someone is having a stroke, it is crucial to seek emergency medical assistance immediately. Early intervention can significantly improve outcomes for stroke patients.

Emergency management of a stroke involves swift action to minimize brain damage and improve outcomes. Time is crucial, and recognizing the signs of a stroke and seeking medical help immediately are essential. The emergency management of a stroke typically involves the following steps:

1. Call Emergency Services:
   • Dial emergency services (e.g., 108 in India) to get professional medical help promptly.
   • Provide information about the person’s condition and the onset of symptoms.
2. Stay Calm and Reassure the Person:
   • Stay with the person and keep them calm.
   • Reassure them that help is on the way.
3. Note the Time of Symptom Onset:
   • Note the time when the symptoms first appeared. This information is crucial for determining treatment options.
4. Do Not Drive to the Hospital:
   • It is generally safer for the person experiencing a stroke to wait for emergency medical services rather than attempting to drive to the hospital.
5. Perform Basic First Aid:
   • If the person loses consciousness and is not breathing, begin CPR (cardiopulmonary resuscitation) if you are trained to do so.
   • If the person is conscious, help them sit or lie down in a comfortable position.
6. Do Not Give Medications:
   • Avoid giving the person any medications, including aspirin, unless directed to do so by emergency medical personnel.
7. Prepare for EMS Arrival:
   • Clear a path for emergency medical services (EMS) personnel to access the person quickly.
   • Provide any additional information about the person’s medical history or medications if available.
8. Transport to the Hospital:
   • The person experiencing a stroke will likely need to be transported to the hospital for further evaluation and treatment.
9. Alert the Hospital in Advance:
   • If possible, call ahead to the hospital to alert them that a person with suspected stroke is on the way. This helps the hospital prepare for immediate assessment and treatment upon arrival.

Prompt and coordinated care is crucial in the management of a stroke. Timely interventions, such as administering clot-busting medications (if the stroke is ischemic) or performing surgical procedures, can significantly improve outcomes and reduce the risk of long-term disability. Always follow the guidance of emergency medical professionals for the best course of action.
