Symptom 9. Memory Problems and Difficulty Concentrating – A Lesser-Known Sign of Low Iodine
Problems with memory and difficulty concentrating are other symptoms that could hint at low iodine levels. While we often associate these symptoms with stress or aging, they could also be a result of iodine deficiency.
Thyroid hormones, which depend on iodine for their production, are crucial for brain function. They play a key role in the growth and development of the brain during infancy and childhood. However, their role doesn’t stop there. Even in adulthood, these hormones are essential for maintaining brain health and function.
Thyroid hormones influence various aspects of brain function, including memory, attention, and cognitive abilities. They play a key role in the process of neurogenesis – the creation of new neurons in the brain. They’re also involved in synaptic plasticity, which is the ability of the brain to form and reorganize synaptic connections, especially in response to learning or experience.
Low levels of iodine can lead to a decrease in the production of these vital hormones, which can affect the functioning of the brain. This can manifest as difficulties with memory, such as forgetfulness or trouble recalling information. You might also experience problems with concentration, making it harder for you to focus on tasks at hand. (9)
