Thyroid Disorders

Thyroid function is intricately connected to brain function through an area of the brain called your hypothalamus. An appropriate amount of thyroid hormone promotes neuroplasticity (or the brain’s ability to change and adapt), increases healthy brain function and decreases neurodegeneration. If the thyroid is playing a role in your neurological symptoms, we want to understand what your thyroid health looks like and how we can help.

Thyroid Function Starts in the Brain

The cascade for proper thyroid function starts in the brain with the hypothalamus, which is a relay center of information from the body to the brain, connecting the nervous system to the endocrine system and more.


The hypothalamus sends signals to the pituitary gland to tell the rest of our glands such as our thyroid, adrenals, ovaries, testes, pancreas and more to make hormones. In order for the hypothalamus to do its job properly, our brain and gut must be able to make adequate amounts of neurotransmitters such as dopamine, serotonin and GABA.


With a full understanding of how the brain, thyroid and GI system work together, we’re able to get to the root cause of your thyroid , brain and immune issues.

Indications that you may have improper thyroid function affecting your brain:

  • Tired/sluggish

  • Cold hands, feet, or all over

  • Require excessive amounts of sleep to function properly

  • Increase in weight even with low-calorie diet

  • Gain weight easily

  • Difficult, infrequent bowel movements

  • Depression/lack of motivation

  • Morning headaches that wear off as the day progresses

  • Outer third of eyebrow thins

  • Thinning or excessive hair loss on scalp, face or genitals

  • Dryness of skin or scalp

  • Mental sluggishness/brain fog

  • Dizziness


  • Heart palpitations

  • Inward trembling

  • Increased pulse even at rest

  • Nervous and emotional

  • Insomnia

  • Dizziness

  • Night sweats

  • Tired but wired

  • Difficulty gaining weight

Thyroid Evaluation

At Carolina Functional Neurology Center, we always run a full thyroid panel, including antibodies, to assess function and pin down the root cause of your symptoms. We recommend a full thyroid panel that gives you a comprehensive overview of the thyroid puzzle. The full panel includes TSH, T4, T3, Free T4, Free T3, Reverse T3, T3 uptake, TPO antibodies, TSI antibodies, Thyroglobulin antibodies and Thyroid binding globulin.

Diagnostic Testing for Thyroid Disorders

  • Neurologial Exam
  • Other specialty labs may be recommended by your doctor to further investigate the root cause of your thyroid dysfunction (ie. stool test to evaluate gut health)
  • Blood Work

I was diagnosed with Hashimoto Thyroiditis in January of 2017. But had been experiencing symptoms since September of 2016. As a mother of two children my symptoms were getting in the way of taking care of my two babies and interfering with my daily life. I was so fortunate to get in touch with Dr. Dana Brindisi at exactly the right time. I literally owe my health to her. She immediately dove into my case and ordered the necessary blood work to get us rolling in the right direction. After receiving the results, we did a virtual consultation and she set up a protocol for me. The supplements she started me on, as well as, the diet and lifestyle changes she recommended took an immediate effect. Within weeks I was less irritable, had little to no brain fog, was sleeping through the night, was finally losing some of the extra weight I gained during my second pregnancy, and had an increase in energy and libido! Dr. Brindisi honestly took a personal interest in ensuring that I was feeling my best, I could never thank her enough for giving me back my health!
