Ischemic stroke: causes, symptoms, consequences

Ischemic stroke is an acute violation of blood circulation in the brain, for which some portions of it cease to function or die completely. This is a very dangerous condition, the consequences of which are serious for human health. Ischemic stroke requires long-term rehabilitation. This is one of the most common causes of death and disability in the world.

What causes an ischemic stroke?

Ischemic stroke accounts for up to 80% of all strokes. The blood goes to the areas of the brain to the extent necessary, and their work fails. At risk are patients with hypertension, diabetes, atherosclerosis, various heart disease.

There are three types of ischemic stroke.

  • Thromboembolic ischemic stroke occurs due to blockage of cerebral vessels by a blood clot.
  • Hemodynamic ischemic stroke is called prolonged spasms of brain vessels, which often occurs through a pressure drop.
  • Lacunary ischemic stroke – occurs from damage to small arteries due to stable high pressure.

Symptoms of ischemic stroke

Most often this type of stroke develops gradually. Before it can occur ischemic attack minor stroke. If detected, the following symptoms you need to seek medical help:

  • severe headache;
  • dizziness, loss of consciousness;
  • slurred speech;
  • numbness and impaired mobility of the limbs;
  • blurred vision temporary blindness, blurred vision, darkening;
  • hearing loss;
  • the feeling of suffocation.

Unfortunately, more than 60% of mini-strokes remain undiagnosed. Them often is followed by a full ischemic stroke. The symptoms are the same, but lasts a few minutes and for hours.

There are additional signs that help to recognize an ischemic stroke:

  • Numbness or loss of sensation of one half of the body.
  • Violation of the understanding and reproduction of speech.
  • Loss of coordination and balance.

To accurately diagnose a stroke can only doctors. It is necessary to do magnetic resonance imaging, computed tomography, echoencephalography and frontal puncture.

Rehabilitation after ischemic stroke

Prognosis after ischemic stroke may be very different: it all depends on what areas of the brain affected and how much. Most often the consequences of ischemic stroke are disorders of thinking, perception and memory, moving activity, problems with speech, hearing, vision. There may also be changes in behavior and mental state of the person, there are often depression, irritability, isolation, lethargy or aggressiveness. In some patients, these symptoms persist for a month, others six months, some a year or more.

Rehabilitation is essential for full recovery and to prevent secondary strokes. It is best to place it in a special rehabilitation center or a neurological clinic. In the rehabilitation program involved rehabilitation specialists, speech therapists, dieticians, physiotherapists, psychologists. It is necessary to restore the motor activity of man, to restore the tone of muscles, to restore language skills, normalize psychological state of the person.

And, perhaps, the greatest value in the process of successful rehabilitation is played by the desire of the patient to recover and return to the previous life. If a person willpower every day to do exercises, to move, to learn anew words and the like, rehabilitation will be successful. If the patient takes a passive position, it is unlikely to fully recover.
