Symptoms of insufficient blood flow to the brain are often a sign of a serious disorder of cerebral circulation, such as transient ischemic attack (TIA), ischemic stroke, or chronic reduction of blood flow, and can range from mild to life-threatening. This condition occurs when brain cells are not getting enough oxygen and nutrients and can appear suddenly (like a TIA) or gradually. Warning signs include sudden dizziness, weakness or numbness on one side of the body, difficulty speaking or understanding speech, blurred vision or diplopia, severe headache, confusion, loss of balance, and in severe cases, loss of consciousness. This Dr. Toto article has been compiled with the aim of a detailed examination of the common and less known symptoms of blood not reaching the brain, the difference between transient and permanent symptoms, and the importance of immediate action to prevent a complete stroke so that patients can go to medical centers on time.

General symptoms of blood not reaching the brain

lack of blood supply to the brain may occur with different severities; Therefore, depending on the severity of the disease and other underlying factors, the symptoms of blood not reaching the brain are different from one person to another. In mild cases, patients may experience only headache, fatigue and dizziness. But in more severe cases, it can lead to temporary memory loss or more serious movement problems.

However, we usually see most of the signs of blood not reaching the brain in patients' movement, talking, breathing, and balance. These symptoms are often similar to those of a stroke. In general, these symptoms include the following:

• Difficulty in pronouncing words and stuttering
• Difficulty in swallowing
• Double vision or vision loss
• Numbness or tingling, usually in the face, arm, or leg (one side of the body)
• Suddenly falling down (falling attacks)
• Vertigo (feeling of things spinning around you)
• memory loss
• Difficulty walking (unsteady gait)
• Headache and neck pain
• Muscle weakness
• Nausea and vomiting
• Drowsiness or sleep from which the person cannot be woken up.
• Sudden and uncoordinated movements

1. Sudden symptoms on one side of the body

In many patients, the lack of blood reaching the brain affects the functioning of parts of the body. From numbness on one side of the body to a tingling sensation, numbness in the hands or feet, and sudden weakness in the limbs, all are some of the most serious symptoms of insufficient blood flow to the brain. Some patients experience numbness or tingling in the fingertips or under the skin.

Stroke and numbness on the right side of the body related are?

2. Impairment of speech and understanding of words

Not getting enough blood to the brain can have an effect on areas related to speech, and for this reason, speech problems are one of the symptoms of not getting enough blood to the brain. Impaired speech or unclear and unintelligible speech is one of the symptoms that can be attributed to the lack of blood supply to the brain. People may even have trouble pronouncing and saying common words.

3. Impaired vision

Some people face vision problems due to lack of blood to their brain. Double vision, blurry vision and unclear vision are symptoms of insufficient blood supply to the brain. This loss of vision in severe cases may last for some time.

4. Dizziness, imbalance and gait disturbance

Brain hypoxia causes a decrease in blood flow to the brain, especially the parts related to the regulation of body balance; So in some people, symptoms of poor blood flow to the brain may include headaches, dizziness, confusion and loss of balance. This dizziness and loss of balance is sometimes accompanied by tinnitus, and patients also experience this condition in quiet environments.

5. Sudden and severe headache

Decreased blood supply to the brain can cause severe and sudden headaches. Many patients constantly experience a feeling of heaviness in the head. These headaches continue even when sleeping, walking or moving. Headache is one of the most common symptoms of insufficient blood flow to the brain.

Symptoms of insufficient blood flow to the brain in stroke and TIA

If blood flow to the brain is reduced or stopped, brain cells do not receive the nutrients they need. This can prevent them from working properly. In serious cases, this may result in stroke or transient ischemic attack (TIA). In these cases, the most important symptoms of blood not reaching the brain include the following:

• Sudden mental confusion
• Weakness or sudden numbness
• Loss of balance
• Severe and sudden headaches
• Loss of sensation in some parts of the body
• Loss of vision
• Speech disorders

Symptoms of blood not reaching the brain in different parts (front and back)

The three main groups of arteries supply blood to the three main parts of the brain; Therefore, depending on which arteries the blood supply is disturbed, the signs of blood not reaching the brain may be different. If blood supply is disturbed in the posterior parts, the symptoms generally include the following:

• breathing problems
• Heart beat problems
• Disturbance in swallowing
• Visual disorders
Movement problems and loss of balance

On the other hand, the most important symptoms of blood not reaching the brain in the anterior part are:

• Motion defects of the lower limbs
• Paralysis of the face and arm of the opposite side
Urinary incontinence
• sensory deficit
• vibration
• Memory disorders and emotional instability
• Nausea and vomiting

Symptoms of blood not reaching the brain due to pressure drop and heart problems

Low blood pressure and heart problems can also disrupt the process of blood supply to the brain. In this situation, the most important symptoms of blood not reaching the brain include the following:

• Feeling dizzy or lightheaded
• Fainting or losing balance
• Nausea and vomiting
• double vision or blurred vision
• fast or slow breathing
• weakness and lethargy
• Extremely tired feeling and headache
• Confusion and difficulty concentrating

Conclusion

Disturbance in blood circulation to the skull is affected by various factors, and for this reason, the severity and symptoms of blood not reaching the brain may vary from person to person. These symptoms appear depending on the cause of the disease and the part of the brain that is affected, and may last a few minutes or become permanent. با این حال تمامی این موارد جدی هستند و در صورت مشاهده علائم نرسیدن خون به مغز، باید حتما به یک پزشک متخصص نورولوژی مراجعه کنید.
