Hello. This is Dalimchae Korean Medicine Clinic.

Can't Remember What You Were Saying? It Could Be a Brain Warning Sign.

"I can't remember what I was just about to say." This one sentence contains a sense of vague anxiety and frustration. As moments of forgetting where you put your keys or what you went to find on your phone become more frequent, many people worry if something has gone wrong with their brain. These symptoms are hard to dismiss as simple forgetfulness and can be an early signal of cognitive decline. Especially for modern people with high stress and exhaustion, these cognitive decline symptoms are appearing regardless of age.

💡 [Key Answer] 3 most common causes of "forgetting what you were about to say": ① Excessive stress and chronic fatigue / ② Autonomic nervous system imbalance / ③ Decrease in sleep quantity and quality Dalimchae Clinic creates an environment where the brain can rest and recover through autonomic stabilization, helping you regain your memory and concentration.

A commonality among those who complain that "I can't remember what I was just about to say" is that they not only have memory problems but also feel their head is foggy and not clear, and it is harder to concentrate than before. These symptoms can be a signal that the brain is in a state of overload or is not getting enough rest. The brain is an important organ that oversees all functions of our body and is very vulnerable to factors such as stress, lack of sleep, and overwork. In particular, areas such as the hippocampus, which is responsible for the brain's memory and cognitive functions, can be damaged by reacting sensitively to cortisol, a stress hormone.

Brain function decline not only lowers the quality of daily life but can also increase the risk of progressing to mild cognitive impairment or more serious dementia in the long run. Therefore, if these symptoms repeat, it is necessary to make an effort to actively find and improve the cause without taking it lightly.

Yes, autonomic nervous system imbalance is closely related to memory loss and cognitive decline. The autonomic nervous system is a system that regulates essential functions for maintaining life, such as heart rate, digestion, respiration, and body temperature regulation, regardless of our will. It is divided into the sympathetic and parasympathetic nervous systems, and our body maintains a stable state when these two nerves are in balance.

However, when the balance of the autonomic nervous system is broken due to chronic stress, overwork, and irregular lifestyle habits, the brain is placed in a state of constant tension. When the sympathetic nervous system is excessively activated, the brain cannot rest and maintains an always excited state, which can lead to a decrease in memory and concentration. According to a study by the Korea Institute of Oriental Medicine and others published in the journal 『Bioengineering』 on November 1, 2024, a tendency for the parasympathetic nervous system to be more activated was observed in the group showing low cognitive function (LCP) compared to the group showing high cognitive function (HCP). This can be interpreted as the sympathetic nerve activity being relatively low in individuals with decreased cognitive function, leading to the parasympathetic nervous system acting dominantly, and suggests that the balance of the autonomic nervous system can affect cognitive function. This study emphasized the possibility of Pulse Rate Variability (PRV) parameters being used as indicators for early diagnosis and classification of cognitive decline. These research results support the importance of deeply evaluating patients' brain health from the perspective of autonomic balance at the Incheon Cognitive Function Clinic as well.

Korean medicine has long paid attention to improving brain functions, including memory and concentration. Recently, through various clinical studies, scientific evidence is being presented that Korean medicine treatment can have a positive effect on cognitive decline.

According to a retrospective observational study published in 『Frontiers in Neurology』 on October 30, 2024, as a result of conducting a 6-month complex Korean medicine treatment including herbal medicine, acupuncture, and pharmacopuncture for 17 elderly people (average age 69.5 years) with mild cognitive impairment (MCI), a significant increase (F(2.32) = 10.59, p < 0.0001) in the Montreal Cognitive Assessment (MoCA) total score was observed over time. The researchers concluded that these results suggest that a dementia prevention and management program integrating herbal medicine and acupuncture treatment can improve the cognitive function of MCI patients. In particular, this study also observed changes in frontal cortex activity, suggesting the possibility that Korean medicine treatment could have a positive effect on brain activity.

Also, in a clinical study published in 『Pharmacology, Biochemistry and Behavior』 in 2024, cited by 『Hani Times』 in April 2025, as a result of a double-blind clinical trial in which 'HT008-1', a complex prescription based on Chongmyeong-tang, was administered for 12 weeks to 118 adults complaining of memory loss, there was a significant difference in cognitive ability improvement scores such as working memory and delayed recall compared to the control group. This study is an important case scientifically proving that Korean medicine prescriptions can be effective in improving memory in the human body. As such, at Dalimchae Clinic Incheon Branch, we focus on maximizing the brain's recovery ability and regaining autonomic balance based on the latest research results.

At Dalimchae Clinic, we do not see cognitive decline symptoms such as "I can't remember what I was just about to say" as just a problem of memory. We find the root cause in the imbalance of the autonomic nervous system and take autonomic stabilization as the core treatment principle. When the balance of the autonomic nervous system is broken, the brain cannot rest and continues to operate like an overheated engine. This is like the breaker switch not going down, so the light is kept on all night. If the brain does not get enough rest, overall cognitive functions such as memory, concentration, and thinking ability are bound to decline.

We create an environment where the brain can recover itself by regaining the balance of the autonomic nervous system. To this end, we relax excessive tension in the nervous system, improve brain blood circulation, and regulate inflammatory reactions through herbal medicine prescriptions tailored to each patient's constitution and symptoms. In addition, acupuncture treatment is an effective way to regulate the nervous system, calming the over-excited sympathetic nerves and activating the suppressed parasympathetic nerves to match the fundamental balance. This induces deep sleep essential for brain function recovery and contributes to increasing the brain's resistance to stress.

These treatments do not simply suppress symptoms, but are a process of reorganizing the body's system so that the brain can regain vitality and perform its inherent functions. At the Incheon Branch clinic, we can expect synergy effects by approaching from an integrated perspective for those who also complain of other discomforts related to the brain and autonomic nervous system, such as tinnitus, dizziness, and headaches.

If any of the following items apply to you, you need to check your brain's health status and start active management.

• It is frustrating because I can't think of the names of people or words I usually know well.
• I forget what I was saying in the middle, or I ask again about a story I just heard.
• I often forget where I put things and spend a lot of time finding them.
• I feel difficulty in learning new things or handling complex tasks.
• The flow of conversation is often interrupted because I can't think of appropriate words during a conversation.
• I forget appointment times or miss important tasks more often.
• My head feels foggy and not clear, and I feel a decrease in overall concentration.
• I am often tired and don't feel clear even after resting, and it is hard to fall asleep or I wake up often.

Judgment Criteria:

• If 3 or more apply: Suspect autonomic imbalance and early cognitive decline. It is time to consider complex oriental medical treatment for brain health management.
• If 5 or more apply: There is a high possibility that cognitive decline is progressing. Precise diagnosis and immediate visit to Dalimchae Clinic Incheon Branch are recommended.

Q. How is forgetfulness different from cognitive decline? A. Forgetfulness is when you remember the fact that you forgot, but cognitive decline is often when you don't even remember the fact that you forgot specific information. Cognitive decline can be a more serious brain function problem than forgetfulness and requires professional diagnosis.

Q. Can young people also experience cognitive decline? A. Yes, due to modern lifestyle habits such as excessive stress, lack of sleep, and overwork, cases of complaining of cognitive decline and concentration loss are increasing among the younger generation. This becomes the main cause of autonomic nervous system imbalance and brain fatigue.

Q. Can cognitive decline heal naturally? A. Slight forgetfulness due to temporary fatigue can improve with rest, but persistent cognitive decline symptoms are hard to improve naturally. Rather, if left unattended, symptoms may worsen or become chronic, so active treatment and management are important.

Q. How long does memory improvement treatment at Dalimchae Clinic take? A. The treatment period varies depending on the severity of the patient's symptoms, the cause of the onset, and individual recovery power. Generally, significant changes can be expected when consistent treatment and improvement of lifestyle habits are combined for about 3 to 6 months. At Songdo Memory Clinic Dalimchae Clinic, we present the most optimized customized treatment plan for each individual.

Cognitive decline such as "I can't remember what I was just about to say" is not a problem that can be solved by enduring. You no longer have to ignore the signals from your body and brain that you have been sending for a long time. If you approach in the right direction, your body reacts faster than you think. Bring your symptoms exactly as they are. At Dalimchae Clinic Incheon Branch, we will find the cause together and regain the brain's vitality.
