When the cells of the brain lacks oxygen, as occurs in stroke, they lose the ability to properly perform their tasks. The symptoms of stroke depend largely on what part of the brain was struck and the volume of brain tissue damage.
Some of the more mild forms of stroke, do not cause symptoms, but still lead to damage to the brain tissue. This stroke is sometimes called the silent stroke
Stroke - a serious brain injury
.
When symptoms of stroke such as numbness and weakness of the muscles on one side of the body, the brain tissue damage typically occurs on the opposite side.
Symptoms usually appear suddenly stroke - a few seconds or minutes. the more extensive area of the brain affected, the more functions will lose people.
The main symptoms
- Sudden numbness or weakness of the facial muscles, and the muscles in the arms and legs, especially on one side of the face. Loss of the ability to freely move them, and / or loss of sensation may be complete or partial. The affected area may occur tingling.
- Sudden confusion, impaired ability to speak and understand speech. Sometimes the weakness of facial muscles causes increased salivation.
- Sudden blurred vision in one or both eyes.
- Dizziness, loss of the ability to maintain balance, coordination of movements.
- Sudden severe headache, with no apparent reason.
Additional symptoms
In stroke may be other symptoms (following stroke symptoms usually occur in women):
- Shortness of breath and a feeling of tightness in the chest.
- Hiccups.
- The pain in my heart, like a symptom of angina
Symptoms of angina: angina pectoris
.
- Palpitations of the heart.
- Nausea and / or pain in the stomach.
- Sudden pain in the limbs.
Possible symptoms
The following symptoms of a stroke can occur in patients of both sexes:
- Changes in smell, taste, hearing and / or vision (sometimes - their complete loss)
- Sagging eyelids and the weakness of the eye muscles
- The weakening of reflexes such as swallowing reflex and pupil reaction to the change in intensity of light
- Reduced sensitivity and facial weakness
- Weakness sternocleidomastoid muscle
- The weakness of the language (impaired ability to move them)
- Memory Disorders
- Anosognosia (the denial of the patient that he has any health problems).
When symptoms of stroke in themselves or another person should immediately call an ambulance. This is no exaggeration to abuse every second may decide the question of life and death of the patient, and that if he could, if he stays alive, to continue fulfilling life. Stroke is terrible not only a large number of its victims, but also the fact that approximately 30% of the survivors, he takes away the ability to serve themselves.
The symptoms of hemorrhagic stroke
Hemorrhagic stroke is more common in the elderly, with about equal frequency in men and women. But in recent years hemorrhagic stroke significantly "younger" and is no longer a rarity in the age of 40. There he is often in broad daylight and is associated with fatigue or emotional outbursts. Sometimes a stroke is preceded by flushing, headache, vision items in red.
The initial symptoms of hemorrhagic stroke: sudden headache, vomiting, disturbance of consciousness, shortness of breath, rapid or, on the contrary, slow heart rate, hemiplegia (complete loss of movement or paralysis on one side of the body) or hemiparesis (partial paralysis of one side of the body).
The depth of human consciousness can be different, it depends on the degree of cerebral edema. With the development of coma consciousness is completely lost, the response to stimulation is absent, his eyes closed, his mouth half open, his face flushed, his lips with a bluish tint. Frequently observed visible to the eye pulsing blood vessels in the neck, breathing hoarse, with periodic freeze within a few seconds, with labored breath or exhale. The skin is cold, slow heart rate, blood pressure
Blood pressure - dangerous if his swing?
often high, the pupil on the side of hemorrhage is often extended. On the side of the body opposite the lesion in the brain (neural pathways make the crossing and go to the opposite side of the body) often show signs of paralysis: the foot is turned outwards, lifted hand falls limp. Often develop swallowing disorders, urinary retention or urinary incontinence. If there is extensive bleeding, it may appear respiratory disorders and cardiac activity. These symptoms may appear as directed, and after a while.
With less profound disturbance of consciousness, stupor (a state of consciousness is also called hibernation when it was too much stimulation can cause a short in the mind), the patient usually lies with his eyes closed, does not respond to the questions or answers very briefly. Sometimes, such a patient may appear oznoboobraznoe shaking the whole body, fever, sweating, increased as the deepening of delirium.
Even less profound disturbance of consciousness - stunning - is characterized by anxiety, restlessness, motor excitation combined with a slow response, automated movements in healthy limbs. Performing complex action fails.
There are several forms of hemorrhagic stroke: acute (all symptoms develop within a few minutes), acute (sudden onset and the patient's condition deteriorates within a few hours) and subacute (symptoms slowly growing or acute onset replaced improvement, then again deteriorating, and so on) .
Individuals elderly bleeding occur less rapidly than in the young, are often accompanied by impaired consciousness.
Signs of ischemic stroke
Ischemic stroke or cerebral infarction is more common in middle-aged and elderly, but sometimes it can occur at a young age. In men, it is more common than in women.
In some cases, before the stroke occurs short transient ischemic whose symptoms (movement disorders, sensitivity) quickly pass.
Developing ischemic stroke more often at night, but sometimes it happens during the day, after mental or physical exertion, alcohol, heat treatments (eg bath) and so on.
Symptoms of ischemic stroke, hemorrhagic unlike manifest slowly over several days. A feature of ischemic stroke is that it seldom causes a general brain injury with loss of consciousness. Most of its features are hitting certain parts of the brain. Signs of ischemic stroke depend on which areas of the brain affected. It can be motor or sensory disorders, disorders of the senses, and so on. Often developing ischemic stroke after myocardial infarction
