• Presence of a blood clot inside an artery of the brain
• Tightening of a cerebral blood glass.
• Displacement of a clot towards the brain from another organ, generally of cardiac origin.
• Diverse injuries of the cerebral blood glasses.
• The ateroesclerosis with presence of badges of ateroma, which produce these transitory pictures before producing another more important picture
• Illnesses of the blood
• Illnesses of the coagulation
• Inflammatory illnesses of the arteries (vasculitis, spread Lupus eritematoso, etc...)
• Alterations of the arterial tension (high or low)
• The diabetes, advanced age and other diverse general illnesses.

SYMPTOMS

The symptoms of the transitory cerebral Isquemia are similar to a cerebral Ictus or vascular brain has an accident, but only they last minutes or hours, with entire recovery of the same ones.

• 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)
• Alterations in the sight
• Picture of sickness or dizziness.

Also, there can appear palsy of the muscles of the face and extremities.

STUDIES FOR THE DIAGNOSIS

The collection in the case history of all the symptoms as well as his sequence and duration is the most important thing, since they can disappear before coming to the doctor.
The doctor will realize a finished neurological exploration to evaluate the situation at the moment of the study.

There usually appears an increase of the arterial tension and a blow at level carotídeo in the neck.

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.
• An 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.)
• Syphilis Serología
• An electrocardiogram
• A thorax radiography
• Study of autoimmune illnesses

TREATMENT

The first thing that must be done is to recover the cerebral blood irrigation so that a cerebral injury of worse recovery does not take place. It usually do a treatment in diet of hospitable internment while there are realized the first studies of diagnosis and situation of the problem.

If there is a problem of engrosamiento of the blood hydration is administered, if there are problems of coagulation it talks each other with anticoagulants (Heparina, Aspirin or Clodiprogel) or on the contrary. If there is arterial hypertension they happen antihypertensive. Also they usually happen hipolipemiantes as soon as possible and all this medication will fit to a dose adapted to be continued in the long term.

Coercion of cardiac arrhythmias if they are.

In case of ateroma badges at level carotídeo an endarteriectomia will be indicated, by means of surgery.

PROGNOSIS

It can be an isolated picture, but it can be repetitive and for it the treatment of the causes is very important. It is necessary to allow smoking since it is the risk factor with the most important obesity.
