Losing a word mid-sentence. Reading a paragraph three times. Walking into a room and standing there. In your forties and fifties this is one of the most frightening menopause symptoms and one of the least discussed — because the fear underneath it is usually dementia, and that fear is hard to say out loud.

Cognitive symptoms are a recognised part of the menopause transition. Difficulty concentrating, slower word-finding and a sense of mental fuzziness are reported commonly enough that they are described in the menopause literature rather than dismissed as imagination.
For most women the pattern is that it is worst during the transition itself rather than progressive, and it is not the pattern seen in dementia. That is the reassurance most people are looking for — and it is genuine reassurance, not a brush-off.
But “usually menopause” is not the same as “always menopause”. Several conditions produce exactly these symptoms, are common in the same age group, and are treatable. That is the real reason to be assessed rather than to wait it out.
The complaint is rarely forgetting who people are. It is usually word-finding — the word is there and will not come; divided attention — fine on one task, lost when interrupted; working memory — the thread of what you were about to do; and mental fatigue that arrives earlier in the day than it used to.
Those are different from the memory changes that worry a neurologist, and describing yours precisely is genuinely useful information. “I lose words” and “I forget conversations I had yesterday” point in different directions.
It often arrives alongside broken sleep, night sweats and mood change, and those are not a coincidence. Sleep that is fragmented every night degrades attention and memory in anyone, at any age. Some of the fog is the sleep, which is worth knowing because sleep can be addressed.
Thyroid disease is common in women in this age group and an underactive thyroid produces fatigue, slowed thinking and low mood. It is a blood test and it is treatable.
Iron deficiency and anaemia, often from heavy periods during perimenopause, cause fatigue and poor concentration. Heavy bleeding is so normalised that many women never mention it, and the link to how they are thinking is not obvious to them.
Vitamin B12 deficiency, poorly controlled diabetes, obstructive sleep apnoea, depression and anxiety, and a number of everyday medications all produce cognitive symptoms.
This is the honest case for an appointment. Not because brain fog is usually dangerous, but because several of the things that imitate it are fixable and none of them are fixed by assuming it is menopause.
What this clinic does: take the history properly, ask about sleep, bleeding, mood and medication, and arrange the blood tests that separate thyroid disease, anaemia, iron deficiency and B12 deficiency from the menopause transition. If the picture is menopause, discuss the options for managing it — including the non-hormonal ones, and including deciding to do nothing for now.
What this clinic does not do: formal neuropsychological or cognitive testing, and the assessment of suspected dementia. If your history points that way you will be told so and pointed to the right specialist, which is a neurologist or a memory clinic rather than a gynaecologist.
Saying that plainly is more useful than implying we can assess everything. A page that offers to solve a problem it is not equipped for wastes the appointment of the person who needed the other doctor.
Consultation ฿1,500–3,000 depending on complexity, plus the ฿300 clinic service fee. Any tests are quoted before they are done.
Some features make this a different conversation, and they are worth seeing a doctor about promptly rather than at your convenience: getting lost somewhere familiar; difficulty with tasks you have done for years; other people noticing the change before you do; problems with language beyond word-finding; personality or behaviour change; or symptoms that are clearly getting worse month by month rather than fluctuating.
Cognitive symptoms starting before 40, or alongside neurological symptoms such as weakness, numbness or visual change, also need assessing rather than attributing to hormones.
None of that is the common picture. It is here because a page that only reassures is not much use to the one reader who needed to be told to go now.
Protecting sleep does more than any other single thing, and treating night sweats is often how sleep improves. If hot flushes are waking you, that is a treatable cause of the fog rather than a separate complaint.
Regular physical activity, and treating iron deficiency if you have it, are both worth doing on their own merits and both affect how you think.
Practical accommodation is not defeat: writing things down, doing the demanding work at your best hour, and interrupting yourself less. Many women find the symptoms most disabling at work, where being interrupted constantly is the norm.
Results vary between individuals, and what helps depends on what is actually causing it — which is the argument for finding out rather than guessing.
No residency, referral or Thai insurance is needed, and the assessment with its blood tests fits inside a short stay.
You will see a female specialist. Consultations are conducted in English or Thai.
Thyroid, iron, B12 and sleep all produce exactly these symptoms and are all treatable. One appointment and a blood test separate them from the menopause transition. Message us on LINE.
