Cerebrovascular diseases, orcerebrovascular diseases, develop then,When the circulation of blood in this or that part of the brain is temporarily or permanently hampered.
All of us somehow heard about strokes, micro strokes or aneurysms.
These diseases can leave a mark on themselves for life, or even take it away altogether.
At best, all this will remain for us "scary but that it really was, it is important to take maximum care of their habits.
It should also be noted that many people are simply not sufficiently aware of these diseases. Because everything that happens not with us, it seems "somewhere far away we do not attach due importance to these things and do not fully realizeInfluence on the health of our brain factors such as blood pressure, high cholesterolor overweight.
But the large number of deaths that occur every year because of cerebrovascular diseases could be prevented ...
Others, for example, strokes in young people who adhere to a healthy lifestyle, are realities that, of course, go beyond our understanding and logic.
But anyway, there are some aspects that we need to reflect on: prevention, periodic medical examinations, measurement of blood pressure, as well as the analysis of other indicators, no doubt capable of detach from uscerebrovascular diseases.
Believe, thiscosts time and effort.
4 most common diseases of cerebral vessels
As we already noted above, any cerebrovascular disease is caused by the problem of blood supply.
So,any change in blood circulation can lead to the emergence of two types of diseases: ischemic and hemorrhagic.
The first are undoubtedly the most common, and most of them have one cause - atherosclerosis.
On the pages of our blog, we have repeatedly talked about this problem. It occurs when the level of cholesterol in the blood increases significantly, and then this is added to such an intimidating inflammation of the arteries of the brain..
These conditions lead to the development of a slow, constantly progressing and very debilitating illness: the appearance of a plaque on the walls of blood vessels.
This, in turn, causes problems with blood circulation (and blood supply to the brain), and in the long run - cognitive impairment and dementia.
It should be understood that all this is not a joke, and in no case can it be neglected: the preventive measures and healthy habits that we will practice today,we will certainly appreciate in the future,ensuring a high quality of life (and life itself).
1. Thrombosis of the brain
- Thrombosis is an ischemic stroke (acute impairment of cerebral circulation).
- In stroke, in 80% of cases the origin is the same.
- It occurs after narrowing one of the cerebral arteries due to a thrombus blocking the blood flow.
It should be noted that, as a rule,This disease usually manifests itself before the complete closure of the vessels of the brain.
Therefore, it is very important to be attentive to the appearance of the following symptoms:
- Numbness of half of face or one side of body.
- Strong headache.
- Problems with communication (it is difficult to speak and perceive someone else's speech).
- Dizziness and mobility problems (difficult to walk).
- Problems with vision (blurry).
2. Cerebral embolism
Cerebral embolism is another type of cerebrovascular disease of ischemic origin. Only if in the previous case there was a thrombus, now it is "embol" (hence the name).
A thrombus is a blood clot that forms on the wall of an important artery and prevents normal circulation of blood.
Embolism is caused by the "embolus"a piece of an arterial plaque, which came off and reached the brain.
Unlike thrombosis, the embolus is formed far from the place of occlusion, which occurs in the region of the heart.
As for the symptomatology, it is very similar to a thrombosis: numbness of one side of the body, difficulty in communicating... If a patient with cerebral embolism quickly provide assistance, he is usually given a drug called tPA (recombinant plasminogen activator), capable of dissolving this plaque.
The chances of a person's survival in this case are quite large.
3. Cerebral or intracerebral haemorrhage
So, we have already considered the two most common ischemic diseases of the brain. Now let's look at the states caused by the bloodshed.
The most common aneurysms. This is an abnormal dilatation (expansion) of the weak zone of the blood vessel in the brain.
- When this aneurysm bursts, a brain hemorrhage occurs.
- But despite the serious consequences of an aneurysm, ischemic strokes are still the most dangerous and annually take a large number of lives.
Returning to an aneurysm, it should be noted thatthe main problem is the absence of obvious symptoms.
There are people who suffer from an aneurysm (in one of the blood vessels) for several years, not knowing anything about it until it breaks.
4. Subarachnoid haemorrhage
Subarachnoid hemorrhages often occur due to uncontrolled arterial pressure. And this is something that we can not and should not ignore.
In this case, we are also dealing with a rupture of a blood vessel, although here a hemorrhage is located on the surface of the brain.
Blood is in the space between the brain and the skull, in the subarachnoid space, not directly entering the brain.
The hope for a happy outcome depends on the speed of medical care. For this reason, it is very important to know the symptoms:
- Problems with concentration of attention.
- Discomfort in the eyes in bright light.
- Irritability, capriciousness, mood changes.
- Pain in the neck and shoulders.
- Dizziness, nausea and vomiting.
The most frequent and obvious symptom is visual impairment.A person can lose sight for a few minutes, to see optical phenomena or bright flashes of light.
In the presence of the slightest suspicion, you should immediately seek medical help and consult with a specialist.
