Overview
Cognitive impairment refers to a decline in mental functions such as memory, thinking, reasoning, and decision-making. It can range from mild cognitive decline to severe dementia. In Korea, early diagnosis and management are emphasized, with advanced neurology and geriatric centers offering evaluation, treatment, and rehabilitation programs to improve quality of life.
What is Cognitive Impairment?
Cognitive impairment occurs when brain functions are affected by aging, disease, or injury. It can be mild, affecting daily life minimally, or severe, as in dementia or Alzheimer’s disease. Cognitive impairment may result from neurological disorders, vascular issues, metabolic problems, or lifestyle factors.

Causes
- Neurodegenerative diseases (Alzheimer’s, Parkinson’s)
- Stroke or other cerebrovascular diseases
- Traumatic brain injury
- Metabolic disorders (e.g., diabetes, thyroid dysfunction)
- Chronic alcohol use or substance abuse
- Infections affecting the brain (e.g., meningitis, encephalitis)
- Vitamin deficiencies (B12, folate)
Risk Factors
- Advanced age
- Family history of dementia or cognitive disorders
- Cardiovascular disease (hypertension, diabetes, high cholesterol)
- Smoking and alcohol use
- Sedentary lifestyle and poor diet
- Depression or social isolation
- Head injuries or repeated concussions
Complications
- Progressive memory loss and cognitive decline
- Impaired ability to live independently
- Increased risk of accidents and falls
