Short answer

Neurology(신경과) is generally the first specialty to evaluate forgetfulness and memory decline in adults, as neurologists assess whether symptoms stem from neurological conditions. Depending on the patient's age and findings, Psychiatry(정신건강의학과) may also be involved, particularly when mood or anxiety disorders are contributing factors.

Which department

  1. 1Neurology(신경과)
    Neurologists specialize in disorders of the brain and nervous system, making them the primary specialists for evaluating memory decline that may be linked to conditions such as dementia, mild cognitive impairment, or other neurological causes. They are trained to assess cognitive function systematically and to interpret relevant brain imaging and lab findings. — First / second line: In general, starting at a neurology clinic(의원) is a reasonable first step for adults experiencing gradual memory changes. If more advanced testing or specialist evaluation is needed, the clinic may issue a referral(진료의뢰서) to a larger hospital(병원 or 상급병원).
  2. 2Psychiatry(정신건강의학과)
    Memory difficulties can sometimes be closely linked to depression, anxiety, sleep disorders, or chronic stress — conditions that fall within the scope of psychiatry. Psychiatrists can evaluate whether a psychological or mood-related condition is affecting cognitive performance. — First / second line: A psychiatry clinic may be considered as a first visit when memory complaints are accompanied by noticeable mood changes, persistent low mood, anxiety, or sleep disturbance. Depending on the evaluation, care may continue within psychiatry or be coordinated with neurology.
  3. 3Internal Medicine(내과) — General or Geriatric
    Certain systemic conditions — such as thyroid dysfunction, vitamin deficiencies, or metabolic disorders — can present as memory decline, and an internal medicine physician can screen for these underlying medical causes. For older adults, geriatric medicine subspecialists within internal medicine are often experienced in comprehensive cognitive assessments. — First / second line: If the patient has existing chronic medical conditions or no established specialist, starting at an internal medicine clinic for a general workup is a common path. The physician may then coordinate referrals based on initial findings.
  4. 4Family Medicine(가정의학과)
    Family medicine physicians provide broad primary care and can conduct an initial assessment of memory concerns while considering the patient's overall health history. They can coordinate care and direct the patient to the most appropriate specialist. — First / second line: Visiting a family medicine clinic first is a practical option for those who are unsure where to start, as the physician can help triage the concern and issue referrals if specialist evaluation is warranted.

Go to the ER / call 119 if

If any of the following applies, do not choose a department — go to an emergency room or call 119 (Korea's emergency number).

  • Sudden onset of severe confusion or inability to recognize familiar people or surroundings that develops over minutes to hours.
  • Memory loss occurring immediately after a head injury, fall, or accident.
  • Sudden difficulty speaking, understanding speech, or finding words, especially when it appears abruptly.
  • Sudden weakness or numbness on one side of the face or body occurring alongside memory or cognitive changes.
  • Loss of consciousness, seizure activity, or extreme disorientation with no clear cause.

Before your visit

  • Note when the forgetfulness first became noticeable and whether it has been gradually worsening or appeared suddenly.
  • Keep a brief record of specific examples — such as forgetting recent conversations, misplacing objects, or missing appointments — to describe to the doctor.
  • List all current medications, supplements, and vitamins, as some substances can affect cognitive function and the doctor will need this information.
  • Note any other symptoms occurring alongside memory decline, such as changes in mood, sleep quality, headaches, dizziness, or unusual fatigue.
  • If previous medical tests (blood tests, brain imaging, or cognitive assessments) have been done, bring the results or reports to the appointment.
  • Consider whether a family member or close person has noticed changes in your behavior or memory, as outside observations can be helpful information for the doctor.

General principles

Memory decline and forgetfulness can arise from a wide range of causes — from normal aging and stress to neurological, psychological, or systemic medical conditions. Because the underlying cause is not apparent from symptoms alone, a doctor's evaluation is the necessary starting point before any conclusions can be drawn.

In the Korean healthcare system, patients generally start at a local clinic(의원) for an initial consultation. If the doctor determines that more specialized assessment or imaging is needed, they may move up to a larger hospital(병원/종합병원), which can be visited directly with normal health insurance(건강보험) coverage, or to a university hospital(상급종합병원), for which a referral letter(진료의뢰서) is required for insurance coverage purposes.

The evaluation of memory concerns typically involves gathering a detailed history of the symptoms, a review of the patient's overall medical background, and possibly cognitive screening assessments — the specific approach varies by patient and is determined by the attending physician. Imaging studies or laboratory tests may be considered as part of the workup, but what is appropriate for each individual is a clinical decision made by the doctor.

When memory symptoms are evaluated, it is common for more than one specialty to be involved over time, since cognitive health intersects with neurology, psychiatry, and general medicine. Coordinated care between departments is a normal part of this process in Korean hospitals.

FAQ

Should I start at a local clinic or go directly to a large hospital for memory problems?

In general, starting at a local neurology or family medicine clinic(의원) is the typical first step in the Korean healthcare system. If the clinic physician determines that advanced evaluation is needed, they may issue a referral, which is required for health insurance coverage at tertiary hospitals(상급종합병원) such as university hospitals.

How is memory decline different from normal forgetfulness, and does that change which department I visit?

The distinction between age-related forgetfulness and clinically significant memory decline is something a physician assesses based on the pattern, severity, and impact of the symptoms — it is not something that can be determined from symptoms alone. Regardless of this distinction, Neurology(신경과) or a primary care clinic is generally the appropriate starting point for evaluation.

Are there tests commonly used to assess memory and cognitive function in Korea?

Cognitive assessments, blood tests, and brain imaging are among the types of evaluations that may be part of a workup for memory decline, though the specific tests used depend entirely on the doctor's clinical judgment for each patient. General principles of cognitive evaluation are similar internationally, and Korean hospitals are equipped with standard neurological diagnostic tools.

Is the approach different for elderly patients compared to younger adults with memory concerns?

The age of the patient does influence which conditions are considered more likely and how the evaluation is structured — for example, dementia-related conditions are more common in older adults, while younger patients may have different underlying causes. In practice, the department visited may be similar, but the clinical focus and considerations discussed with the doctor will differ based on age and overall health.
