Acute Cerebral Infarction (Ischemic Stroke)

#cerebral infarction, #acute cerebral infarction, #blood clot, #thrombectomy, #FAST

Acute cerebral infarction is a very urgent condition in which a blocked blood vessel in the brain damages brain cells. Time is critical, and rapid recognition and emergency treatment are most important, so please seek immediate medical attention.

Atlantoaxial Instability (Cervical Instability)

#cervical instability, #first cervical vertebra (C1), #second cervical vertebra (C2), #cervical disc herniation, #cervical spine surgery, #rheumatoid arthritis, #cervical fusion, #spinal cord, #numbness in hands and feet, #arm numbness, #tingling leg, #weakness in arms and legs, #difficulty moving one side of the body, #anxious feeling in the chest, #restlessness, #worrying for no reason

Cervical instability (atlantoaxial instability) is a condition in which the connection between the first and second neck bones (cervical vertebrae) becomes loose and allows excessive movement. Mild cases may cause no symptoms, but as it progresses it can compress the spinal cord and lead to serious nerve damage. It is relatively common in patients with rheumatoid arthritis. Please be sure to decide on an accurate diagnosis and treatment approach through a medical specialist.

Cerebral Hemorrhage

#cerebral hemorrhage, #stroke, #cerebral infarction, #intracranial pressure, #blood pressure management, #emergency surgery, #headache, #splitting headache, #migraine, #pain at the back of the head, #body swelling, #facial swelling, #leg swelling, #swollen hands and feet, #weakness in the arms or legs, #difficulty moving one side of the body

Cerebral hemorrhage is a medical emergency in which a blood vessel in the brain ruptures and bleeding occurs. Blood pressure management is the most important way to prevent it, and if symptoms occur, you should go to the emergency room immediately.

Cerebrovascular Disease (Stroke)

#stroke, #cerebral infarction, #cerebral hemorrhage, #thrombolysis, #thrombectomy, #cerebrovascular disease, #winter stroke, #first aid, #post-stroke sequelae, #multidisciplinary care, #headache, #splitting headache, #migraine, #pain at the back of the head, #lightheadedness, #spinning sensation, #unsteadiness, #vision going dark, #weakness in the arms or legs, #difficulty moving one side of the body

Cerebrovascular disease (stroke) is a condition in which a blood vessel in the brain becomes blocked or ruptures, causing brain damage. To minimize aftereffects, prompt emergency response is most important, under the principle that 'time is brain.' The risk of stroke is especially high in winter and during seasonal changes, so please follow the prevention guidelines carefully.

Dizziness

#dizziness, #vertigo, #balance disorder, #cerebral infarction, #orthostatic hypotension, #headache, #splitting headache, #migraine, #pain at the back of the head, #lightheadedness, #spinning sensation, #unsteadiness, #vision going dark, #collapse, #loss of consciousness, #fainting, #weakness in the arms or legs, #difficulty moving one side of the body, #anxious feeling, #nervousness, #worrying for no reason

Dizziness is a general term for a feeling that the surroundings are spinning or that it is hard to keep your balance. It may be caused by something simple, such as anemia or an ear problem, but it can also be a sign of a dangerous brain condition. Because the exact cause must be found and treated, please be sure to consult a medical specialist for an examination.

Moyamoya Disease

#Moyamoya disease, #cerebrovascular, #cerebral infarction, #cerebral hemorrhage, #transient ischemic attack, #revascularization surgery, #pediatric stroke, #headache, #splitting headache, #migraine, #pain at the back of the head, #weakness in the arms or legs, #difficulty moving one side of the body

Moyamoya disease is a rare cerebrovascular disease in which the major blood vessels leading to the brain gradually become blocked and abnormal blood vessels form. It often presents as cerebral infarction in children and as cerebral hemorrhage in adults. Whether symptoms are present or the condition is found incidentally, please consult a neurosurgery specialist.

Retinal Artery Occlusion

#retinal artery occlusion, #retina, #decreased vision, #eye stroke, #central retinal artery occlusion, #high blood pressure, #diabetes, #blurry vision, #difficulty seeing, #hazy vision

Retinal artery occlusion is a condition in which the artery that supplies blood to the retina is suddenly blocked. Like a stroke, in which a blood vessel in the brain is blocked, it damages the nerve cells involved in vision, and it is sometimes called an 'eye stroke.' If sudden vision loss occurs, seek immediate medical attention at an emergency room or ophthalmology department.

Stroke

#stroke, #dementia, #vascular dementia, #high blood pressure, #snoring, #weakness in the arms or legs, #difficulty moving one side of the body

Stroke is a medical emergency that occurs when a blood vessel in the brain becomes blocked or ruptures. A blocked blood vessel is called a cerebral infarction, and a ruptured one is called a cerebral hemorrhage. If symptoms appear, going to the emergency room immediately is the most important way to reduce aftereffects. Stroke is also closely related to dementia. The main symptom of stroke is the loss of a specific bodily function, such as paralysis of the arms or legs. The most important factor in treatment is the golden time (the critical time window for treatment), so please be sure to consult a medical specialist for an accurate diagnosis. If abnormal symptoms appear, call 119 (Korea's emergency number) or go to the emergency room immediately.
