![]() ![]() The current study examines the effect of hypothyroidism on the adult brain, in particular the hippocampus which is an area of the brain that plays a critical role in short and long term memory.Ĭooke GE et al. ![]() However, unlike in congential hypothyroidism, there is limited data on whether hypothyroidism in adults results in structural brain defects. Hypothyroidism is common in adults and is frequently associated with cognitive issues, such as increased forgetfulness, mental slowing and “brain fog”. Because of this, all newborns are screened at birth in order to detect congenital hypothyroidism as early as possible and initiate treatment to prevent impaired brain development. In fact, congenital hypothyroidism is the most common preventable cause of mental retardation. It is well known that hypothyroidism during pregnancy and infancy can impair brain development. T 4 gets converted to the active hormone T 3 in various tissues in the body. Thyroxine (T 4): the major hormone produced by the thyroid gland.

The technique is widely used in hospitals for medical diagnosis, staging of disease and for follow-up without exposure to ionizing radiation. MRI scanners use strong magnetic fields and radiowaves to form images of the body. MRI (Magnetic Resonance Imaging): a medical imaging technique used to investigate the anatomy and function of the. Humans have two hippocampi, one in each side of the brain. Hippocampus: Part of the limbic system of the brain which plays an important role in short and long term memory. Treatment requires taking thyroid hormone pills. ![]() Hypothyroidism: a condition where the thyroid gland is underactive and doesn’t produce enough thyroid hormone. ![]()
