103. Stroke precursor symptoms, causes, treatment, prevention


Stroke self diagnosis

  1. The most common hemiparesis, hemiparesthesia
  2. Vomiting occurs repeatedly along with severe headaches
  3. Paralysis of one or all sides of the face
  4. Dizziness where the surroundings spin around
  5. Dysarthria that causes slurred speech
  6. Poor comprehension, aphasia
  7. Decreased vision, double vision where objects appear overlapped
  8. Difficulty eating food or swallowing water

Because the roles and functions of each cerebral blood vessel are different, the symptoms of stroke are very diverse depending on the blood vessel causing the problem or the location and extent of the damaged brain.


If the above situation persists, be sure to get diagnosed at a hospital.



Stroke, a medical emergency, occurs when there is a disruption in the blood supply to the brain. This can lead to serious consequences, including disability and even death. We’ll delve into the world of strokes, exploring their causes, symptoms, self-diagnosis methods, prevention strategies, and the crucial actions to take during the “golden time” when a stroke occurs. Remember, timely intervention can make all the difference in stroke outcomes.



1. Stroke: The Silent Threat

A stroke is a sudden and often debilitating medical condition that occurs when there’s a disturbance in the blood flow to the brain. This can happen due to a blockage (ischemic stroke) or the rupture of a blood vessel (hemorrhagic stroke). Strokes are a leading cause of long-term disability and the fifth leading cause of death in the United States.


2. Recognizing Precursor Symptoms

Before a full-blown stroke occurs, some individuals may experience precursor symptoms or warning signs. These can include sudden and severe headaches, transient numbness or weakness in the face, arm, or leg (especially on one side of the body), confusion, trouble speaking or understanding, vision problems, dizziness, and loss of balance or coordination. Recognizing and acting upon these early symptoms is crucial.


3. Stroke Symptoms: Act Fast!

Stroke symptoms are often sudden and can vary depending on which part of the brain is affected. Common symptoms include:




  • Sudden numbness or weakness in the face, arm, or leg, especially on one side.
  • Sudden confusion, trouble speaking, or difficulty understanding speech.
  • Sudden trouble seeing in one or both eyes.
  • Sudden trouble walking, dizziness, loss of balance, or lack of coordination.
  • Sudden severe headache with no known cause.

If you or someone you’re with experiences these symptoms, it’s essential to act quickly. Time is of the essence when dealing with a stroke.


4. Self-Diagnosis: The FAST Test

To quickly assess a potential stroke, you can use the FAST test:


  • Face: Ask the person to smile. Does one side of their face droop?
  • Arms: Ask them to raise both arms. Does one arm drift downward?
  • Speech: Have them repeat a simple sentence. Is their speech slurred or strange?
  • Time: If you observe any of these signs, it’s time to call 911 immediately.

5. Understanding Stroke Causes

Strokes have various underlying causes, including:




  • High blood pressure (hypertension)
  • Atrial fibrillation (an irregular heart rhythm)
  • Smoking
  • Diabetes
  • High cholesterol levels
  • Family history of stroke
  • Obesity
  • Physical inactivity
  • Excessive alcohol consumption

Identifying and managing these risk factors can significantly reduce the likelihood of experiencing a stroke.


6. Transient Ischemic Attack (TIA): A Warning Sign

A TIA, often referred to as a “mini-stroke,” is a temporary disruption of blood flow to the brain. While TIAs do not cause permanent damage, they serve as a warning sign that a full-blown stroke may be imminent. Seek medical attention promptly if you experience TIA symptoms.


7. The Golden Time for Ischemic Strokes

Ischemic strokes, which result from blood clots blocking blood vessels in the brain, have a “golden time” for treatment. If identified within hours of symptom onset, clot-busting medications can be administered to restore blood flow and minimize brain damage. It’s imperative to seek medical help immediately if you suspect an ischemic stroke.


8. Hemorrhagic Strokes

Hemorrhagic strokes occur when a blood vessel ruptures and causes bleeding in the brain. They are often associated with severe headaches, nausea, and vomiting. Treatment may involve surgery to repair the damaged blood vessel.


9. Stroke Prevention: Knowledge Is Key

Preventing strokes involves managing risk factors such as high blood pressure, diabetes, and high cholesterol. Additionally, adopting a heart-healthy lifestyle that includes regular exercise, a balanced diet, and not smoking can significantly reduce the risk of stroke.


10. Aphasia: A Common Stroke Consequence

Aphasia is a language disorder that can result from a stroke, affecting the ability to speak, understand, read, or write. Rehabilitation and speech therapy are essential components of recovery for individuals with aphasia.


11. Foods for Brain Health: Nourish Your Mind

Maintaining brain health is essential for overall well-being and cognitive function. The foods you consume can have a significant impact on your brain’s health and performance. Here are some foods that are beneficial for brain health:


  • Fatty Fish: Fatty fish like salmon, trout, and mackerel are rich in omega-3 fatty acids, particularly DHA. Omega-3s are crucial for brain health, as they support brain cell structure and function. They have been linked to improved memory and cognitive function.
  • Berries: Blueberries, strawberries, and other berries are high in antioxidants that help protect the brain from oxidative stress and inflammation. These antioxidants may delay brain aging and improve memory.
  • Leafy Greens: Leafy greens such as spinach, kale, and Swiss chard are packed with vitamins and antioxidants. They are rich in folate, which may help improve cognitive function, and vitamin K, which is essential for brain health.
  • Nuts and Seeds: Almonds, walnuts, flaxseeds, and chia seeds are excellent sources of antioxidants, healthy fats, and vitamin E. Vitamin E, in particular, has been associated with reduced cognitive decline as you age.
  • Avocado: Avocado is a source of monounsaturated fats that support healthy blood flow, which is essential for brain health. They also contain folate and vitamin K.
  • Whole Grains: Whole grains like oatmeal, whole wheat, and brown rice provide a steady supply of energy to the brain. They are a good source of fiber and essential nutrients that support cognitive function.
  • Turmeric: Turmeric contains curcumin, a powerful anti-inflammatory compound. Curcumin has been shown to cross the blood-brain barrier and may have neuroprotective effects, potentially reducing the risk of neurodegenerative diseases.
  • Eggs: Eggs are rich in choline, a nutrient that supports brain health and memory. Choline is a precursor to acetylcholine, a neurotransmitter involved in memory and learning.
  • Dark Chocolate: Dark chocolate, in moderation, can improve brain function. It contains flavonoids that enhance memory, attention, and mood by increasing blood flow to the brain.
  • Green Tea: Green tea contains L-theanine, an amino acid that can have a calming effect on the brain. It also contains antioxidants called catechins, which may help protect brain cells.




12. Foods to Limit or Avoid for Brain Health

While certain foods can enhance brain health, it’s equally important to be mindful of foods that may have a negative impact on cognitive function. Here are some foods to limit or avoid:


  • Processed Foods: Highly processed foods are often high in added sugars, unhealthy fats, and artificial additives. They can lead to inflammation and have a detrimental effect on brain health.
  • Sugar-Sweetened Beverages: Sugary drinks like soda and fruit juices can lead to obesity and type 2 diabetes, which are risk factors for cognitive decline.
  • Trans Fats: Trans fats, found in some margarines and processed foods, are known to promote inflammation and increase the risk of dementia.
  • Highly Refined Carbohydrates: Foods made with white flour and refined sugars can lead to blood sugar spikes and crashes, negatively affecting brain function.
  • Excessive Alcohol: While moderate alcohol consumption may have some benefits for brain health, excessive alcohol intake can lead to cognitive impairment and brain damage.
  • Saturated and Trans Fats: High intake of saturated and trans fats found in red meat, fried foods, and processed snacks has been associated with a higher risk of cognitive decline.
  • Excessive Salt: High sodium intake may lead to high blood pressure, which can increase the risk of stroke and cognitive impairment.
  • Artificial Sweeteners: Some studies suggest a potential link between artificial sweeteners and negative effects on cognitive function. Further research is needed, but it’s wise to consume them in moderation.
  • Too Much Caffeine: While moderate caffeine intake can boost alertness, excessive consumption can lead to anxiety and disrupt sleep patterns, affecting overall brain health.
  • Heavy Red Meat Consumption: Consuming large amounts of red meat, particularly processed meats like bacon and sausages, has been associated with cognitive decline. Opt for lean cuts and limit processed meat intake.


A balanced and brain-friendly diet rich in whole foods, antioxidants, and omega-3 fatty acids can help support cognitive function and protect against age-related brain conditions. Be mindful of foods that may harm your brain health and strive for a well-rounded diet to nourish your mind for a lifetime of optimal function.
