Have you ever heard of the term "Hypertensive Encephalopathy"? It may sound like a bit of a serious name because it has a lot of letters, right? Simply put, this is a condition where the pressure in your body, that is, blood pressure, suddenly increases to a point where it affects the functioning of your brain. This is not something to be trifled with, because this is a condition that requires emergency medical treatment. Today, we will talk about this clearly and in a way that you can understand.
What exactly is Hypertensive Encephalopathy?
Okay, let's start from the beginning. "Hypertensive" means high blood pressure. "Encephalopathy" means a change or impairment in the functioning of the brain. Then when these two are combined, hypertensive encephalopathy is a temporary disruption of brain function due to high blood pressure. In this, the main thing that is seen is a change in your mental state.
Now you know, as blood flows through our body's veins, it exerts a certain amount of pressure on the walls of those veins. That's what we call blood pressure, or "pressure." Normally, a healthy person's blood pressure is less than 130/80 mmHg (millimeters of mercury). But when this hypertensive encephalopathy condition develops, the pressure can go as high as 220/130 mmHg. Sometimes, it is said that this condition can occur even at a level of 160/100 mmHg.
The most important thing is that this is a medical emergency, even a life-threatening one. Therefore, if you notice symptoms, it is best to seek medical advice immediately.
How common is this condition?
In fact, high blood pressure emergencies occur in less than 2% of all patients who come to hospital emergency rooms. However, hypertensive encephalopathy occurs in about 15%. This means that it is not something that happens to everyone, but if it does, prompt treatment is essential.
What are the symptoms? How can you recognize it early?
In this condition, the symptoms do not come on suddenly. They develop gradually. Therefore, it is very important to be aware of these symptoms.
The first possible symptoms are:
- Headache: This can be a severe headache that gets worse and worse. It can feel like someone is pressing on the inside of your head.
- Fatigue: Excessive tiredness felt even after doing nothing.
- Nausea: Feeling like you're going to vomit.
- Vomiting: Sometimes vomiting may occur.
Then you may experience symptoms that affect your mental state:
These symptoms are what tell us that this situation is serious.
- Confusion: A state of not knowing where you are, what time it is, or who you are.
- Personality changes: Changes such as suddenly becoming angry or agitated.
- Restlessness: The inability to stay in one place and moving around.
- Vision loss: Vision may suddenly become blurred or completely lost.
- Seizures: Body twitching, similar to a fit.
- Loss of consciousness: You may lose consciousness and fall. This is the most dangerous situation.
If you or someone you know has one or more of these symptoms, along with high blood pressure, call 911 immediately or go to the nearest hospital emergency room. Time is of the essence at a time like this.
Why is this happening? What are the reasons?
Simply put, the main cause of hypertensive encephalopathy is very high blood pressure. Imagine, what happens if you send water faster than a water pipe can handle? The pipe can be damaged, right? That's how it is, the high pressure starts to damage the delicate blood vessels in the brain. Then a water-like fluid starts to leak from those blood vessels into the brain. We call this cerebral edema. That's when the brain's function becomes disrupted.
Who is more likely to develop this? (Risk factors)
Some people are more likely to develop this condition. Let's take a look at who they are:
- People who don't know they have high blood pressure: Many people don't even know if they have it because they don't check their blood pressure. Such people can suddenly go into a dangerous situation like this.
- People who suddenly stopped taking blood pressure medication: It is very dangerous to stop taking medication on your own without consulting a doctor.
- People with kidney disease: The kidneys are an important organ that helps control blood pressure in our body. When you have kidney disease, your blood pressure is more likely to increase.
- Women who develop high blood pressure (eclampsia) during pregnancy: This is also a condition that requires great care.
- People receiving certain cancer treatments (chemotherapy): Some cancer medications can cause increased blood pressure as a side effect.
What complications can this cause? Is it serious?
Yes, if this is not managed properly, serious complications can occur.
- Permanent brain damage: If not treated quickly, permanent damage to brain cells can occur.
- Cerebral edema: As we mentioned before, this is the main issue.
- Damage to other organs: High blood pressure can cause kidney failure, vision loss, and heart attack.
- Coma: A state of unconsciousness, similar to falling into a deep sleep.
- Life-threatening: If left untreated, death can occur.
That is why this is considered an emergency.
How do doctors diagnose this? (Diagnosis)
When you go to the emergency room, the doctors will first check your mental status and blood pressure. They will do a general physical exam and a neurological exam to check your brain function. They will also ask about your medical history, any medications you are currently taking, and any medications you have recently stopped.
In addition to measuring the pressure, several other tests can be done to see if other organs have been damaged:
- Blood tests: Check things like kidney function and blood salt levels.
- ECG test (Electrocardiogram): Look at the electrical activity of the heart.
- Chest X-ray examination.
- Brain CT scan or MRI scan: To check for swelling or bleeding in the brain.
All of this is how doctors accurately diagnose hypertensive encephalopathy.
How to treat?
The main goal when treating this is to lower your high blood pressure as quickly, but safely, as possible.
Emergency treatment
- Antihypertensive medications: These medications are not given by mouth at first. They are given through a small cannula placed in a vein in the arm. This makes it easier to control the pressure accurately.
- Intensive care unit (ICU) care: While you are being treated, doctors and nurses will take good care of you. This treatment is usually done in an intensive care unit (ICU).
- Speed of lowering blood pressure: Imagine that your blood pressure is 220/120 mmHg. Then, within the first hour, the pressure is reduced by between 10% and 15%. It is not reduced by more than 25% within 24 hours. Because, if you reduce it too much all at once, the blood vessels in the brain do not have enough time to heal, and other problems such as stroke may occur. Therefore, the dosage of the medicine is made very carefully.
- Oral medication: Once the pressure is controlled, oral medication can be started after 8 to 24 hours.
- Seizure treatment: If you experience seizure-like symptoms, you may be given medication for that as well for a short period of time.
Long-term management
Even after you go home from the hospital, your doctor will likely tell you to continue taking your blood pressure medication (oral antihypertensive medications). These medications can help keep your blood pressure under control. They will also tell you to make a few lifestyle changes:
- Diet control: Reduce salt (sodium), reduce oily foods.
- Exercise: It is very good to exercise daily.
What medications are used for treatment?
There are several types of fast-acting/rapid-onset antihypertensive medications available to treat this condition. For example:
- Nicardipine
- Labetalol
- Hydralazine
- Fenoldopam
- Clevidipine
- Sodium nitroprusside
These are not medicines you can just take. They are given by a doctor in a hospital.
Are there any side effects of the treatment?
Yes, there may be some side effects when lowering blood pressure too quickly. But don't worry, doctors are paying attention to that too.
- Tiredness
- Dizziness, feeling lightheaded
- Fainting
- Kidney injury
- Stroke
Because these side effects are very serious, you will be closely monitored throughout your treatment.
How quickly will I recover after treatment?
As your blood pressure starts to come down, you will start to feel better. This usually happens within 24 to 48 hours. However, depending on how much the encephalopathy has affected your brain function, it may take several days, or even weeks, to fully recover. If complications develop, the recovery time may be longer.
What is the outlook for this situation? (Outlook)
The good news is that if treated quickly and properly, the effects of hypertensive encephalopathy can be reversed. That is, as the pressure decreases, the symptoms caused by the damage to the brain gradually disappear. However, if you have other comorbidities along with high blood pressure, you are more likely to develop complications. That is why doctors will monitor you closely during treatment.
After you have been treated for this condition, your doctor will check your blood pressure regularly. See how well your blood pressure is controlled with the medication you are taking. If you can, get a blood pressure monitor at home and record your blood pressure as your doctor tells you. If you have any side effects, tell your doctor . Never stop taking your blood pressure medication without your doctor's advice.
Can't this be prevented? What can be done?
Although it cannot be completely prevented, you can significantly reduce this risk by controlling your blood pressure. Here are some things you can do to do this:
- Eat a healthy diet: Eat more fruits and vegetables. Reduce oil, salt, and sugar.
- Reduce salt intake: Consume less than 2 grams of salt per day.
- Regular exercise: Something like walking for at least 30 minutes a day.
- Avoid using tobacco products: Stop smoking cigarettes completely.
- Managing stress: Things like meditation and yoga can help.
- Limiting alcohol consumption.
- Taking the blood pressure medication prescribed by the doctor exactly and on time.
When should I see a doctor?
If you have high blood pressure, it's important to see your doctor regularly for checkups. Your doctor will give you the right treatment and monitor how it's affecting you. Remember, don't stop taking your medication without your doctor's advice. If you develop any new symptoms or side effects, tell your doctor .
When should you go to the hospital immediately? (ETU)
If you have the symptoms of hypertensive encephalopathy that we discussed earlier (such as severe headache, confusion, blurred vision, seizures), call 911 or go to the nearest hospital emergency room without delay. High blood pressure is dangerous and can be life-threatening if not treated promptly.
What are the important questions to ask the doctor?
When you go to see a doctor, it's a good idea to ask these questions:
- How can I control my blood pressure?
- What kind of treatment do you recommend for me?
- Are there any side effects to those treatments?
- What should I avoid eating and drinking to stay healthy?
- What types of safe exercises can I do?
Final Take-Home Message
True, controlling your blood pressure is not an easy task. Maintaining a healthy lifestyle takes time, energy, and dedication. But, think about how dangerous a condition like hypertensive encephalopathy, which is caused by high blood pressure, can be. Although it can be cured if treated quickly, the best thing to do is to prevent it before it occurs. To do this, work with your doctor to properly control your blood pressure. Do not stop taking your blood pressure medication without your doctor's approval for any reason. Your health is in your hands!
