Does Thyroid Disease Cause Memory Loss

Emotional Causes Of Memory Loss

Thyroid Brain Fog and Memory Loss With Hashimoto’s, Graves’ and Hypothyroidism

Because our mind and body are connected and affect each other, our emotions and thoughts can impact our brain. The energy it takes to cope with certain feelings or life stress can get in the way of storing or remembering details and schedules.

Often, these emotional triggers of memory loss can be improved by support, counseling, and lifestyle changes. Even just being aware ofand limiting exposure tothings that increase stress can help.

Quality Of Life And Fatigue

Many clinic patients complain of poor quality of life and fatigue, which are often associated with psychiatric co-morbidity, and which prompt a screening TSH measurement. If the TSH level is mildly elevated, the patient and provider assume the mild hypothyroidism has caused the symptoms. However, these symptoms often do not resolve with L-T4 treatment, raising the question of whether they were due to the thyroid abnormality in the first place.

Recent studies have demonstrated that a mildly elevated TSH level is not intrinsically associated with poor quality of life or fatigue, but that self-knowledge of a thyroid condition is associated with decrements in these measures, regardless of the TSH level:

  • A population-based survey in the Netherlands measured the intensity of fatigue in almost 6000 subjects aged 1898 years . The prevalence of fatigue in euthyroid subjects with no known thyroid disease was 34%, and was similar in overt or subclinical hypothyroid subjects . In subjects with known thyroid disorders, the rate of fatigue increased to 50%, and was independent of the TSH level.

  • A separate population-based study in the Netherlands administered the SF-36, a widely used validated quality of life scale, to over 9000 subjects aged 1890 years, who were unaware of their thyroid status . SF-36 scores were indistinguishable between subjects with elevated versus normal TSH levels.

  • Dementia Case Finding Procedures

    Dementia and its subtypes were identified in a multi-step case-finding procedure, described in detail elsewhere . In brief, all participants underwent neuropsychological screening with the 100-point Cognitive Abilities Screening Instrument , a measure of global function that has been validated in English and Japanese . Diagnosis was based on neuropsychologic testing using the Consortium to Establish a Registry for Alzheimer Disease battery, a neurologic exam and an informant interview. Those with dementia received a work-up with neuroimaging and blood tests. All recognized subtypes of dementia were considered in the diagnostic consensus conference that included a neurologist and at least two other study investigators. Dementia was diagnosed according to DSM-III-R criteria , probable and possible AD according to National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer Disease and related Disorders Association criteria , and vascular dementia according to California Alzheimer Disease and Treatment Centers criteria . The remaining subtypes included subdural hematoma, Parkinson disease, cortical Lewy body disease, Pick disease, and cause not determined. Among participants who received autopsy evaluation, approximately two-thirds of the clinical Alzheimer cases met CERAD neuropathologic criteria for AD .

    Thyroid Treatment Can Help

    Fortunately, there is an effective treatment available for those with thyroid problems. The thyroid hormone levels can be adjusted through the use of oral medications, radioactive iodine, and/or surgeries.

    So, can this treatment help people with thyroid disorders who are experiencing cognitive problems? Although there is some question of the effectiveness of treatment with significantly older adults, most research shows that cognitive functioning improves when thyroid disorders are treated.

    In fact, the good news, according to the Rancho Bernardo study, is that people who’ve been treated with supplemental thyroid therapy show no decline in cognitive functioning.

    When To Contact Your Doctor

    If youve checked off signs and are not feeling yourself, discuss this with your primary care doctor. These signs dont necessarily mean that you have thyroid disease. By asking you about your symptoms, your doctor can decide whether you need a blood test to check for thyroid disease.

    Ways To Naturally Address Dental Problems

    While nothing can replace a trip to the dentist, there are a few things you can do to keep your teeth in tip-top shape. While keeping your mouth healthy wont avoid thyroid problems, it can minimize thyroid-induced complications in your mouth while also protecting your heart.

    Quick reference for a nightly dental routine: Youll want to oil pull first , then floss, brush, and finally, use mouthwash at the end.

    The list of symptoms linked to thyroid disease is long. Weight fluctuations, hair loss, vision changes, skin problems, memory problems, sensitivity to hot and cold and menstrual disruption are just a few of the symptoms associated with thyroid problems. One often-overlooked set of symptoms is the problems thyroid disease can cause in the mouth. Thyroid hormone imbalance is behind several mouth and dental health issues.

    Burning Mouth Syndrome

    Some thyroid patients, especially women in middle age or in menopause, develop Burning Mouth Syndrome, or BMS. As the name suggests, BMS is characterized by a burning sensation on the tongue or the lips or involving the whole mouth. It may be accompanied by a bitter or metallic taste. Treatment for thyroid disease can improve the symptoms of BMS.

    Thyroid Memory Loss and Forgetfulness – Keep your mind sharp!

    If youre not sure if loss of memory warrants a doctor visit, consider:

    • Does your memory loss disrupt daily activities?
    • How often do the lapses occur?
    • Whats being forgottendetails of a conversation, or the conversation in its entirety?
    • Are there signs of confusion ?
    • Is the memory loss getting worse?

    If someone is having trouble remembering the day of the weeknot the date, but Monday, Tuesday, Wednesdaythats concerning, says Dr. Karlawish. Other concerning signs are repetitive questions: They get an answer, then several minutes later, they ask the same question. Or they repeat a story: something about a recent event, but then 20 minutes later, they tell you the same story.

    Its not unusual for people to deny theyre having memory problems or to downplay the issue, but a prompt diagnosis is important.

    Arrive at some reasonable, common understanding that you ought to get it looked into, says Dr. Karlawish. They dont have to agree on everything youve seen, and you dont have to make it a confrontation. Just get to the point where you can agree that Gee, it would be good to get this checked out. Then, the key is to go with them to the appointment.

    You dont need to find a specialist for an initial consultation. Instead, look close to home.

    Start with a doctor who knows you well, so a primary care physician, says Dr. Karlawish. Ideally, people go in with someone who knows them wella spouse, child or close friendwho can speak to what theyve been seeing.

    Constipation Is A Symptom Of Hypothyroidism

    Hypothyroidism, or an underactive thyroid, is a defined as a disorder of the endocrine system wherein the butterfly-shaped gland doesnt produce a sufficient amount of thyroid hormone for proper function.

    Hypothyroidism occurs due to a number of causes including treatment for hyperthyroidism, autoimmune disease, thyroid surgery, radiation therapy, and some medications.

    Symptoms of hypothyroidism vary and they depend on the severity of your condition. Many people dont even know they are hypothyroid because symptoms develop over the years, they dont pop up unexpectedly. Plus, signs of hypothyroidism are similar to those of other conditions thus making it more difficult for people to understand whats going on.

    One of the most common symptoms of hypothyroidism is constipation. Others include weight gain, fatigue, low libido, abnormal menstrual cycle, memory loss, depression, hair loss, dry and pale skin, dry hair, cold intolerance, muscle cramps, and irritability.

    Constipation being a symptom of hypothyroidism isnt the only link between two conditions. Lets inspect this relationship more thoroughly.

    Why Does Hypothyroidism Cause Constipation

    As seen throughout this post, current evidence confirms the relationship between constipation and hypothyroidism. Youre probably wondering why that happens in the first place. While exact mechanisms arent fully investigated, the culprit could be the fact that insufficient levels of thyroid hormones slow down the bodys functions.

    Just like the above-mentioned studies revealed, hypothyroidism slows function of digestive tract thus causing irregular bowel movements or making it difficult for a person to eliminate waste from the body.

    Moreover, digestive tract including both large and small intestine are lined with muscles. The proper function of these muscles is important for healthy digestion and bowel movements. In order to move waste or stool through the intestine to the rectum and out of the body, muscles need to contract.

    Due to hypothyroidism contraction of muscles slows down and weakens. As a result, stool also moves slowly, and you experience infrequent bowel movements or difficulty passing stool.

    Not only is constipation uncomfortable and frustrating, particularly when its chronic, but it can also decrease the efficacy of medications youre taking. After all, therapy needs to be fully absorbed in order to work, but digestion-related problems like constipation impair absorption.

    This only emphasizes the importance of management of constipation.

    What Is The Connection Between The Thyroid And The Brain

    Do Thyroid Disorders Cause Forgetfulness and Brain Fog?

    For thyroid hormones, thyroxine and triiodothyronine to cross the blood-brain barrier, a transfer protein is required. Transthyretin , found in the serum and cerebral spinal fluid functions to move thyroid hormones into and around the brain where they provide neuronal and glial maintenance.5-7

    In a very early study,8 investigators revealed lower levels of circulating TTR in patients with hyperthyroidism. In addition, they reported a negative correlation between TTR and free T4 levels with increased fT4 associated with lower TTR. When patients were treated for hyperthyroidism, an increase in TTR levels occurred as they shifted to a more euthyoidal state.8 Findings from another study demonstrated that TTR levels in spinal fluid were lower in individuals diagnosed with Alzheimers disease.9

    Thus, the connection between hyperthyroidism and dementia was made the significance of this association and to what degree these two conditions intersect was the aim of this recent Danish study.4

    Many Said They Had Symptoms Well Before A Hypothyroidism Diagnosis

    byKristen Monaco, Staff Writer, MedPage Today May 30, 2021

    Nearly half all patients with hypothyroidism reported experiencing “brain fog,” even before receiving a diagnosis, a researcher reported.

    In an online survey of over 5,000 people with hypothyroidism, 905 said they experienced new-onset brain fog symptoms in the weeks or months following their initial diagnosis, according to Matthew Ettleson, MD, of the University of Chicago.

    But 46% of all patients questioned said they experienced brain fog symptoms prior to receiving their hypothyroidism diagnosis, Ettleson explained in a presentation at the American Association of Clinical Endocrinology virtual meeting.

    The vast majority of these patients with brain fog symptoms said they experienced them frequently or all of the time.

    In regard to hypothyroidism etiology, about half of those who reported these new brain fog symptoms after diagnosis had undergone thyroid surgery and/or radioactive iodine therapy therapy. Another third had Hashimoto’s disease, and the latter was more common among the patients who experienced brain fog prior to their hypothyroidism diagnosis.

    The top symptom reported regardless of hypothyroidism etiology was fatigue, marked by lack of energy or feeling sleepy. Other symptoms of hypothyroidism-related brain fog included forgetfulness, difficulty making decisions, and mental confusion, as well as anxiety and depressive symptoms.


    Dementia Doesn’t Always Mean Alzheimer’s

    Dementia is any memory loss or thinking problem caused by changes in your brain. Alzheimer’s is just one type. Your memory also can be harmed by many other health issues, such as a stroke, Parkinson’s disease, or a buildup of fluid on your brain.

    If you notice symptoms that have you concerned, see a doctor right away. They’ll give you a thorough exam that may include taking a sample of your blood for testing, brain imaging, and neurological testing to figure out what’s going on with your health and get you help.

    Although your thyroid gland sits deep in your neck, your dermatologist may be the first doctor to notice signs of thyroid disease. Thats because many signs and symptoms of thyroid disease develop on the skin, hair, and nails.

    The thyroid gland

    The thyroid is a butterfly-shaped gland in your neck that produces hormones, which play a key role in regulating your heartbeat, breathing, and many other functions.

    You, too, may also be able to spot thyroid disease, and thats important. Caught early, treatment can prevent complications. When thyroid disease goes untreated for years, it can lead to a dangerously slow heartbeat, an injury that refuses to heal, or unrelenting pain. You may have gained or lost weight for no apparent reason.

    Hormonal changes are closely linked to sexual function. If you find that your period is becoming irregular, heavier, or more painful than before, or if you are experiencing stronger emotional symptoms tied to PMS, your thyroid might be the cause.

    You might also experience difficulty with sexual performance or enjoyment. If you are having difficulty with libido or achieving orgasm or if you cannot maintain an erection, you could also be struggling with a thyroid-related symptom.

    While these are uncomfortable issues to talk about, they should absolutely be addressed with us to rule out not only thyroid trouble but also anything else that might quietly be causing these issues.

    What Can You Do To Treat Thyroid Brain Fog Naturally

    As well as thyroid medication, stabilization of blood sugar through a balanced diet also helps produce more ATP in the brain, says Sears. Ultimately, people with thyroid and brain fog issues should understand that it is a real metabolic event that can be treated with the appropriate hormones and dietary changes.

    Often, inflammation starts in the gut, the home of most of the bodys immune system. Improving gut health is one way to improve the efficacy of the immune system, which can have a positive effect on brain and thyroid function.

    Reducing or eliminating inflammatory foods and substances like processed meat, alcohol, caffeine, refined carbohydrates, and artificial trans fats may help improve gut function, and reduce gastrointestinal stress. Adding a probiotic to your diet can also improve gut function by encouraging the production of good bacteria.
