BRAIN FOG GUIDE
Are you feeling dizzy and having
trouble connecting your thoughts?
Brain fog is not the name of the disease. This refers to the feeling of difficulty concentrating and slow thinking. Several causes, including sleep, fatigue, medications, and physical condition, must be examined together.
4big cause
Sleep and fatigue · Physical condition · Medication and stress · Symptoms that appear togetherYou cannot determine the cause based on feelings alone.
STRUCTURE×FUNCTION
PATIENT WORDS
Patients express this feeling.
SIGNAL CHECK
This may appear as a feeling of lightheadedness.
What is more important is when it started and when it gets worse, rather than how many there are.

POSSIBLE CAUSES
Bar length does not indicate the likelihood of illness. This is an easy-to-view summary of commonly checked items.Since there may not be just one cause, we
start by looking at clues in daily life.

CLINICAL MAP
The reasons for starting the
same daze may be different.
If you look at when it gets worse and how much you need to rest to get better, the order of finding the cause becomes clearer.

DIAGNOSTIC SYSTEM
The confirmation needed varies from person to person.
First check when symptoms occurred and changes in your life, and select testing items only when necessary.
Standing and balance function evaluation
Depending on the symptoms, changes in standing posture, gait, and balance function are objectively checked.
EEG/quantified EEG
It is not applied uniformly to all patients and is selected as an adjunct when there are clinical clues for seizures or functional evaluation.
Autonomic function evaluation
When dizziness, palpitations, discomfort in standing, and recovery rhythm occur together, we examine necessary items such as HRV.
Check blood and body condition
Screen for correctable causes that may be associated with symptoms, such as anemia, thyroid, metabolic and nutritional conditions.
ONE-STOP TOTAL CARE
Find the cause and determine
the order of daily recovery.
Rather than the name brain fog, the next steps are determined based on the identified cause and the most uncomfortable part of daily life.
- 01
listen to the story
We first hear when the discomfort began and how it changes after sleep and activity.
- 02
Confirmation required
Select only the checks you need based on your symptoms and previous test results.
- 03
daily recovery plan
Symptoms that appear along with sleep and activity are adjusted according to the identified cause.
- 04
Check the changes
Determine the next steps by looking at what has improved in your daily life and what continues to be uncomfortable.
PERSONALIZED SOLUTION
Adjust one by one according to the cause found.
We don't apply the same method to everyone. We sequentially look at symptoms that appear along with sleep, life rhythm, and medications taken.
Adjusting your sleep and rest habits
In addition to how long you sleep, we also look at whether you sleep regularly and how much you move and rest during the day.
Check your physical condition and medications
Check the medications you are taking and possible causes such as anemia, thyroid, and nutritional status.
Adjusting concentration load and activity level
Divide your concentration time into rest periods, and slowly adjust the intensity if you feel worse after the activity.
Check for symptoms that appear together
Look for symptoms that appear together, such as headaches, dizziness, and discomfort when standing up.
