Schizophrenia is a major mental illness in which the ability to distinguish reality from one's own thoughts and perceptions is impaired. In Korean, the disorder was previously called jeongsinbunyeolbyeong (literally, "split-mind disease") but was renamed johyeonbyeong in 2011; the new term means "tuning the strings," reflecting the idea that mental confusion arises when the brain's neural signaling is not properly tuned. With appropriate treatment and management, people with schizophrenia can maintain daily functioning.

#seasonal affective disorder, #depression, #major depressive disorder, #fall depression, #winter depression, #amount of sunlight, #circadian rhythm, #mood disorder, #lack of energy, #fatigue, #feeling tired all the time

Seasonal depression is a condition in which depression appears repeatedly and is closely tied to a particular season, such as fall or winter. The accurate diagnostic name is "major depressive disorder, with seasonal pattern." Changes in the amount of sunlight and disruption of the body's circadian rhythm are presumed to be among the causes. If low mood is serious enough to interfere with daily life, please consult a psychiatrist.

Please consult a medical specialist for an accurate diagnosis and direction of treatment.

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.

Tongue cancer is a malignant tumor that develops in the tongue and accounts for about 10 to 15% of all head and neck cancers. Because early symptoms resemble those of stomatitis (mouth sores), it is often left untreated and found late. Treatment outcomes tend to be better when the cancer is detected early, so if you have a sore on the tongue that does not heal or a lump you can feel, please consult a medical specialist without delay.
