Unlocking Memory Mysteries: Thyroid and Cognitive Wellness

Experiencing brain fog, forgetfulness, or signs of dementia can send ripples through your spine. While numerous causes for such symptoms may exist, an unlikely yet common culprit is your thyroid.

The thyroid gland has an intricate connection with your memory. Therefore, understanding this relationship is the key to improving your cognitive health.  So, keep reading to learn how thyroid function affects memory and how Supreme Vascular Interventional Clinic can support your recovery.

Relationship Between Thyroid Function and Memory

The thyroid, a butterfly-shaped gland in your neck, is pivotal in regulating various bodily functions, including metabolism and energy production. However, its influence extends to cognitive functions as well. The thyroid hormones thyroxine (T4) and triiodothyronine (T3) are essential for proper brain function.

When the thyroid is underactive (hypothyroidism) or overactive (hyperthyroidism), it can lead to cognitive issues, including memory impairment. In hypothyroidism, a lack of thyroid hormones can slow down brain function, causing forgetfulness and difficulty concentrating. On the other hand, hyperthyroidism, an excess of thyroid hormones, can lead to anxiety and memory-related problems.


Brain Fog

One of the prevalent symptoms associated with thyroid-related memory issues is brain fog. It’s a term often used to describe a feeling of mental confusion or lack of mental clarity. Individuals experiencing brain fog may struggle to concentrate, remember things, or think clearly.


Forgetfulness (Memory Loss)

Memory loss is another common manifestation of thyroid dysfunction. You may notice that you forget names, appointments, or where you place everyday items. This forgetfulness can range from mild to severe, depending on the severity of thyroid dysfunction.



While severe cases of thyroid dysfunction can contribute to cognitive decline, it’s essential to note that dementia is not a direct consequence of thyroid issues. However, untreated thyroid disorders can exacerbate cognitive decline in individuals already predisposed to dementia.


Tips to Improve Mental Health

Fortunately, there are lifestyle changes and interventions that can support cognitive health in the context of thyroid function. Here are some practical tips to consider:

  • Balanced Diet: Maintaining a balanced diet is crucial for overall health, including cognitive function. Ensure your diet includes a variety of fruits, vegetables, whole grains, and lean proteins.
  • Foods to Include and Avoid: Incorporate foods rich in essential nutrients like omega-3 fatty acids, antioxidants, and vitamin B12. Limit the intake of processed foods, sugary snacks, and excessive caffeine, as they can negatively impact cognitive function.
  • Nutrients and Vitamins Supplements: If your diet lacks certain nutrients, consider supplements after consulting your healthcare provider. Vitamin B12, omega-3 fatty acids, and vitamin D are important for brain health.
  • Medication: Thyroid medication prescribed by your healthcare provider can help regulate thyroid hormone levels, potentially improving cognitive symptoms.
  • Saturated Fats: Reduce the intake of saturated fats, commonly found in fried foods and processed snacks, as they may contribute to inflammation and negatively impact cognitive health.
  • Regular Exercise: Engage in regular physical activity, as exercise has been shown to support cognitive function and reduce the risk of cognitive decline.
  • Quality Sleep: Ensure you get adequate and quality sleep, as sleep is essential for memory consolidation and overall cognitive health.
  • Monitor Thyroid Levels: Regularly monitor your thyroid hormone levels through blood tests. This allows your healthcare provider to adjust your treatment plan if needed.


Thyroid Nodules

Thyroid nodules are solid or fluid-filled lumps that form within the thyroid. Though common, they can sometimes lead to thyroid dysfunction and impact memory. If you have thyroid nodules, it’s essential to keep monitoring their status and potential effects on cognitive health.

If you notice thyroid nodules through sight or touch, seek immediate treatment. In this regard, radiofrequency ablation (RFA), a minimally invasive treatment, is the ideal option. RFA involves using thermal energy to shrink or eliminate thyroid nodules, restoring thyroid function and potentially alleviating associated cognitive symptoms. Read our blog post on a few things to know in detail about thyroid nodules and how thyroid nodule radiofrequency ablation (RFA) treatment can help.

Understanding the intricate connection between the thyroid and memory is vital for maintaining cognitive health. If you’re experiencing memory issues, especially in conjunction with thyroid nodules, seeking professional advice is crucial. 

At Supreme Vascular and Interventional Clinic, our thyroid nodule specialist, Dr. Manish Taneja, is dedicated to providing compassionate care and personalized treatment with comprehensive thyroid care to ensure the best possible outcomes for all patients. Our services include ultrasound-guided biopsies, thyroid function testing, and surgical management of thyroid nodules including minimally invasive treatment options like radiofrequency ablation. Contact us today to schedule a consultation and take the first step toward improving your cognitive health.

Thyroid Nodule Radiofrequency Ablation (RFA) Treatment

Radiofrequency ablation aims to give patients a non-surgical option for treating thyroid nodules. This procedure is a minimally invasive option that a surgeon can perform, should the preliminary tests determine that you would benefit from it.

The Advantages of RFA of Thyroid Nodules

The major advantages of the technique are as below.

  1. It is done as day surgery procedure under light sedation.
  2. It takes about 45 minutes to one hour to complete the entire procedure.
  3. Patients are discharged the same day.
  4. Normal thyroid tissue adjacent to the nodule is preserved.
  5. It does not affect thyroid function.
  6. Multiple nodules can be treated at same time.
  7. The treated nodules do not regrow again.
  8. No surgical scar with needle mark on the skin.
  9. Quick recovery and back to full activity and normal lifestyle.
  10. The technique is suitable to treat even large thyroid nodules.

How to Keep Thyroid Healthy for Optimal Well-Being

As part of the endocrine system, the thyroid hormones must be perfectly balanced at all times for the body to function normally.

Caring For Your Thyroid Health

Have you ever experienced difficulty swallowing or breathing? You may have risk factors including a family history of thyroid nodules or iodine deficiency. Thyroid nodules are abnormal lumps (growths) within the thyroid gland, a butterfly-shaped gland located below your voice box. Even if most thyroid nodules are benign, 10-15% of nodules are cancerous. Sometimes overgrowth of normal thyroid tissue can lead to hyperthyroidism. In other cases, multiple nodules can form in the thyroid called multinodular goiter. Fluid filled thyroid cysts can be one type of thyroid nodule within the thyroid. More complex nodules may lead to thyroid cancers.

Depending on the root cause and type of nodule you have, patients can monitor with regular ultrasound or even have a thyroid fine needle aspiration biopsy (FNAC) if required. Surgery to remove partial or whole thyroid gland can be done but thanks to minimally invasive treatments such as Radiofrequency Ablation (RFA), this procedure can treat noncancerous and cancerous thyroid lumps.
