Dementia Prevention

#dementia prevention, #three do's and three don'ts, #depression, #stress, #aerobic exercise

Dementia does not appear suddenly; it results from harmful changes that accumulate in the brain over a long period of time. Building good habits in daily life from a young age is the best way to help prevent it. Making an ongoing effort to protect one's own health is especially important. If you or a loved one notices signs of memory loss or other cognitive changes, please consult a medical specialist.

Dysphagia (Swallowing Disorders)

#swallowing disorder, #dysphagia, #aspiration, #swallowing rehabilitation, #diet modification, #stroke, #swallowing test, #fever, #feeling hot, #high fever, #low-grade fever, #dry cough, #minor cough, #persistent cough

Dysphagia is a condition in which the ability to swallow food or drink is impaired. If 'aspiration,' in which food enters the airway, occurs, complications such as pneumonia may develop. If you suspect a decline in swallowing function, please consult a medical specialist for examination and testing.

Early-Onset Dementia (Young-Onset Dementia)

#early-onset dementia, #young-onset dementia, #alcohol-related dementia, #lifestyle diseases, #vascular dementia

Dementia is not a disease that affects only older adults. Dementia that develops at a relatively young age, between 45 and 65, is called early-onset (presenile) dementia. Because it tends to progress faster than dementia in older adults, please consult a medical specialist without delay if symptoms occur.

Epilepsy

#epilepsy, #ganjil (former Korean name), #convulsion, #seizure, #antiepileptic drugs, #neurology, #convulsive seizure

Epilepsy is a condition in which seizures occur repeatedly because of abnormal electrical signals in the brain. In Korean it used to be called 'ganjil,' but the name was changed to 'noejeonjeung' in 2012. Epilepsy is not a single disease but a group of conditions that arise from various causes. If you suspect symptoms, please be sure to consult a neurology specialist.

Forgetfulness and Dementia

#forgetfulness, #dementia, #mild cognitive impairment, #memory, #brain cells, #stress, #trouble falling asleep, #frequent waking, #poor sleep quality

It can be difficult to tell whether forgetfulness is simple age-related forgetfulness or a sign of dementia. Forgetfulness is a normal experience, but dementia is a brain disease. Rather than judging this on your own, please consult a medical specialist if you notice any concerning symptoms.

Hearing Loss

#hearing loss, #hearing, #hearing aid, #cochlear implant, #bone conduction hearing aid, #auditory rehabilitation, #sensorineural hearing loss, #conductive hearing loss, #ringing in the ears, #noise in the ear, #cannot hear, #difficulty hearing sounds

Hearing loss refers to a condition in which hearing is reduced and it is hard to hear sounds properly. It has many causes, including aging, noise, and otitis media. According to data from the Health Insurance Review and Assessment Service, the number of patients with hearing loss has been steadily increasing. If you feel your hearing is declining, please do not put it down to age; consult an otolaryngology (ENT) specialist to have the exact cause diagnosed.

Hearing Loss and Bone Conduction Hearing Aid Implantation

#hearing loss, #sensorineural hearing loss, #conductive hearing loss, #hearing aid, #bone conduction hearing aid, #cochlear implant, #presbycusis, #otitis media, #external auditory canal atresia, #dementia, #cognitive decline, #cannot hear, #difficulty hearing sounds

Hearing loss is not just a symptom of difficulty hearing sounds; it affects overall quality of life, including withdrawal from relationships, depression, and cognitive decline. In recent years, bone conduction hearing aid implantation, which delivers sound through the bone, has been used for patients who have difficulty using conventional hearing aids. If your hearing declines, please do not leave it untreated by blaming 'age'; consult a medical specialist.

Hip Fracture

#hip fracture, #fall, #femur, #hip bone fracture, #joint replacement, #fracture fixation, #osteoporosis, #fracture in older adults

A hip fracture is the most serious type of fracture that occurs after a fall. The hip joint is the joint where the pelvic bone and the thigh bone (femur) connect. After a fracture, a person cannot bear weight or stand, which makes walking independently difficult, and in older patients it can lead to complications such as pneumonia, pressure sores, and sepsis, so mortality is high. If you have pain in the hip or upper thigh after a fall, please consult an orthopedic specialist right away.

Neurogenic Bladder

#neurogenic bladder, #overactive bladder, #urinary incontinence, #residual urine, #bladder function, #stroke, #Parkinson's disease, #diabetes mellitus, #urodynamic study, #clean intermittent catheterization

Neurogenic bladder is a condition in which a problem in the nervous system, such as the brain, spinal cord, or peripheral nerves, prevents the bladder from storing or emptying urine properly. Symptoms are often mild at first and easy to overlook, but without treatment, serious complications such as urinary tract infection and kidney failure can occur. If you have an underlying condition such as stroke or diabetes mellitus, please have your bladder function checked regularly.

Orthostatic Hypotension

Orthostatic hypotension is a condition in which blood pressure drops sharply when a person suddenly stands up from sitting or lying down, causing dizziness, fainting, and other symptoms. It can also occur in people with high blood pressure. Some studies link it to an increased risk of dementia, so if symptoms recur, please consult a medical specialist.

Periodontal Disease (Gum Disease)

Gum disease (periodontal disease), marked by bleeding and swollen gums, is not limited to the mouth — it can worsen systemic conditions such as dementia, heart disease, and diabetes. Regular visits to a periodontal specialist and routine dental scaling are essential.

Pneumonia in Older Adults

Pneumonia in older adults generally refers to pneumonia that occurs at age 65 or older. Pneumonia is inflammation of the lungs caused by infection with bacteria, viruses, or other organisms. More than 50% of people with pneumonia and more than 90% of people who die of pneumonia are aged 65 or older. In older adults, symptoms are often not obvious, so diagnosis is easily delayed. If you have suspected symptoms, please consult a pulmonology and allergy specialist immediately.

Sleep is an important time for the brain to recover from fatigue and organize memories. Sleep disorders are more than a simple inconvenience; they are associated with cognitive decline and an increased risk of dementia. If sleep problems persist, please consult a medical specialist.

Smoking, Health, and Quitting Smoking

#Smoking, #Smoking cessation, #E-cigarettes, #Nicotine, #Tar, #Lung cancer, #Cardiovascular disease, #COPD, #Smoking cessation medication, #Nicotine addiction, #Weakness in arms or legs, #One-sided weakness, #Chest anxiety, #Restlessness, #Unexplained worry, #Feeling down, #Lack of motivation, #Not wanting to do anything

Both regular cigarettes and e-cigarettes are harmful to health. Smoking raises the risk of many conditions, including lung cancer and other cancers, cardiovascular disease, and chronic obstructive pulmonary disease (COPD). Quitting smoking is not easy, but getting help from a medical specialist makes success more likely. If you've decided to quit, please work with a healthcare team rather than trying on your own.

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.
