Effect Of Hypothyroidism Can Hurt Brainpower

If you are among the 4 to 15 % of Americans who are walking around with sub clinical hypothyroidism, which means that initial signs of an underactive thyroid, you might face above the normal mild fatigue, dry skin, weight gain, and other symptoms of slow thyroid.


Research Findings on the Effect of Hypothyroidism

According to a fresh review of studies, people who are below 75 with sub clinical hypothyroidism are at “substantial risk” of dementia or cognitive damage.

When the the researchers, in Italy, examined the outcomes of 13 studies based on the Effect of Hypothyroidism hypothyroidism, which is defined as raised serum TSH – thyroid-stimulating hormone and T4 – normal thyroxine levels—they discovered about 56 % augmented impaired cognitive function risk and an 81 % amplified dementia risk. The precise nature of “impaired cognitive function” diversed somewhat from one research to another which depends on their used rubric—any of some standardized tests like the Wechsler Memory Scale-Revised scores, Wechsler Adult Intelligence Scale and the (MMSE) Mini Mental State Examination.

Non-specific, Mild, neuro-cognitive symptoms might be perceived in sub clinical hypothyroidism. People having such symptoms should have a test of their thyroid function—and if they are evidently sub clinical hypothyroid, then the levothyroxine therapy must be considered.

Other Studies on Effect of Hypothyroidism

Whereas numerous studies have inspected this matter previously, this study is novel in that it is the first to contemplate the patients’ age—which impacted the findings dramatically. It appears that our levels of TSH tend to increase along with age, such that at the time when we are above over 80, the TSH’s upper limit has been observed to become above 6 to 7. In these research studies, the people were considered to be having sub clinical hypothyroidism if their levels of TSH were more than 4 to 5.

Unfortunately, since the sub clinical hypothyroidism symptoms are either much understated or not obvious at all—you could brush them off easily as normal aging signs, the condition might go untreated for many years. When this occurs, when your thyroid gland is continually being roused to release additional amount of hormones, it could cause an enlarged thyroid (goiter), and you can turn out to be vaguer, your thought processes might slow, and you might feel depressed.
