DEFINITION
An accident vascular brain is the loss of the neurological functions for lack of blood irrigation owed in this case to the presence of badges of ateroma for an ateroesclerosis.
CAUSES
 |
|
The arterioesclerosis is very frequent and it is the cause of more than half of the accidents brain vascular. The ateroesclerosis takes place for the accumulation of greasy textile and other substances in the internal walls of the arteries, then they press the step of the blood hard and also they make them more rigid and less flexible.
Sometimes the break of a badge can produce small injuries and clots that become detached and are circulating producing muddles of circulating textile, when the artery becomes closer the clot remains fitted producing an entire closing of the blood step and a second time a suffering for loss of irrigation of the awkward area of this blood glass. When this area is in the cerebral area vascular brain produces the accident to itself.

The factors of risk of producing an accident vascular brain are:
- Presence of arterial hypertension
- Attacks isquémicos transitory previous
- To be a smoker
- Peripheral vascular illness
- High cholesterol
- Diabetes
- Obesity
- Sedentarismo
SYMPTOMS
One or several can appear symptoms in case of accident vascular brain for arterioesclerosis:
- Drowsiness and pins and needles of face or extremities.
- Weakness, sensation of heaviness in the extremities
- Uncoordination of voluntary movements (to swim, to take things with the hands, etc...)
- Alterations in the speech (I stutter, bad pronunciation, not to be able to speak)
- Alterations in the sight
- Alterations of the memory
- Picture of sickness or dizziness
- Also there can appear palsy of the muscles of the face and extremities
- Incapability to recognize or to identify sensory stimuli (agnosia)
- Make difficult for deglutir
- Alterations in the personality, frame of mind and in the emotions
- Urinal incontinence and of dregs.
- Loss of conscience, drowsiness or lethargy
METHODS OF DIAGNOSIS
In the sharp moment it is necessary to raise a diagnostic study to need an immediate treatment of the picture with:
- Analytical of finished blood (Hematimetria and VSG), I study of coagulation (time of protombrina)
- A study will be realized with Cerebral Scanner (TAC) or Nuclear Magnetic Resonance. vUna ultrasound scan doppler of the artery carotid
- Ecocardiograma
- Sometimes it is possible to go so far as to realize a cerebral arteriografía
Later a study of the possible causes will be realized by means of:
- Blood glucose
- Finished analysis of biochemistry of the blood, with glycemia
- Lipidograma (cholesterol, triglicéridos, etc...)
- An electrocardiogram
- A thorax radiography
TREATMENT
Before the suspicion of a cerebrovascular acccidente it is very important to come quickly to a hospitable center, this time is essential for `poder to do a diagnosis and immediate treatment, which can determine to a great extent the resolvión and/or recovery of the symptoms.
The most effective treatment for an accident vascular brain is the TROMBOLISIS ENDOVENOSA by means of the supply of rtPA that is a medicine that works dissolving the causative clot of the problem. If this medicine is received in the first 3 hours after the beginning of the first symptoms, he can help to prepare the permanent problems. Nevertheless, there is a risk of bled important with this treatment therefore it is not possible to use in all the cases.
The patients not capable of this treatment one gives them an anticoagulant treatment (Heparina, Aspirin or Clodiprogel), antihypertensive medication and hipolipemiantes.
For the recovery motorboat will be needed of a rehabilitation and of the speech.
PROGNOSIS
25 % of the persons who suffers an accident vascular brain recovers the majority or all his functions. Later there are diverse percentages for the different aftermath.
It is necessary to support the treatment with anticoagulant, antihypertensive and hipolipemiantes of for life.
