Danger of atherosclerosis is that the disease may be asymptomatic / almost asymptomatic for many years. Clinically, the disease manifests itself only when atherosclerotic plaque grows so much that overlaps the bloodstream. And this leads to brain tissue ischemia, developing vascular encephalopathy.
Signs of atherosclerosis heads appear only after some time (long enough) once began to gather cholesterol on vascular walls. Symptoms become noticeable when the diameter of the main arteries (and also the smaller brain capillaries) is narrowed so that the volume of incoming blood is lowered not less than 15%.
Emerging signs of disease over time will vary depending on the stage of its development, because the changes occurring in atherosclerosis with an organism are different at different stages.
The initial stage is characterized by fatigue, weakness and lethargy man, his fatigue and inability to concentrate and to perceive information. However, this occurs only with increased physical activity and / or growth of psychological and emotional stress. Some patients in this period complaining of sleep disturbances, headaches, tinnitus.
Progress of atherosclerosis is accompanied by hypochondria, mood swings in patients with other psychiatric disorders. People are prone to anxiety, depressive states. They have violated the memory, head aches constantly, and tinnitus is only strengthened. If the main artery of the brain overlap is strong enough, the patient has speech disturbances, dizziness, unsteady gait. As deteriorating hearing and vision, the patient becomes unable to complete a productive activity. A tremor of the limbs and head deprives him of the ability to think logically clear.
The final stage of the disease - it is, as a rule, dementia or dementia. Intelligence patient significantly weakens a person thinks and behaves like a child. He may become aggressive and / or whiny. Most of these patients lose their memory and interest in the proceedings. They are unable to have to navigate in space, time. Require constant monitoring and care, as completely lose self-service skills.
Last stage head atherosclerosis actually is irreversible and has no direction to weaken and reduce symptoms. So it is important to identify any atherosclerotic changes in vessels still in the early stages. Only in this way, starting adequate therapy, it is possible to try to keep the patient at least a basic self-service skills and memory leftovers.
