Testosterone And Cognitive Functions

The Effects Of Testosterone On Your Brain

Most of us know the physical benefits of having good testosterone levels. But did you know that it can also have a profound effect on your mental and cognitive functions too.

This article covers the relationship between testosterone and brain function.


Cognitive Function and Testosterone

Testosterone levels in a healthy man should range between 300ng.dl and 1000ng.dl. From our thirties, its quite natural for our natural testosterone production to reduce, usually by 1-2% per year.

Should they drop below 300ng.dl, you are officially classed as being hypogonadic.

“In other words you have low Testosterone.”

Reduced testosterone has many different effects on the body. We can start to feel weaker, our muscle mass can reduce ( medically called sarcopenia).

Our coordination can sometimes suffer, along with our movement and balance.

When we think abut Low Testosterone, we tend to consider the physical and perhaps sexual side effects, as these seem to be the most talked about, and are in fact the most obvious to anybody suffering with low T.

Scientists however have determined a defined link between our male sex hormones and our brain. In particular the key cognitive functions – Memory, attention, learning and focus.

Just How Are Cognitive Functions And Testosterone Linked?

As we get older, it’s not uncommon to see our mental abilities decline. This coincides with reduced testosterone levels. Experts do believe that our steroid hormones are directly linked to emotional and cognitive functions.

It has been shown that by maintaining Testosterone levels, we are able to protect ourselves from mild cognitive impairment (MCI).

This is where our cognitive effects are reduced, but not so much that it truly impacts our lives ( like dementia for example).

One particular study published in the European Journal Of Endocrinology demonstrated that low testosterone levels in men was directly linked to poor or reduced cognitive functions in men.

They suggested that a testosterone boosting supplement could help improve mental ability.

Another key study proved that testosterone was found to play a key role in enhancing memory by increasing the biological processing of information

Not all studies have recorded the same results however. One trial involving men with very low testosterone ( readings of 128ng.dl) saw no cognitive improvement after taking 200mg of testosterone every 3 weeks.

The journal of Clinical Endocrinology and Metabolism  reported that tests on healthy older men showed that lower than normal testosterone levels impaired cognitive functions.

Where as those with higher levels faired much better in cognitive tests.

The men with low T showed significant signs of reduced ability to process visual information, reading maps for instance, playing certain sports and even driving

A similar study confirmed that an 8 week course of testosterone boosting supplements normalised cognitive ability in most men.

Testosterone Could Also Be Linked To Dementia

It is believed that testosterone has a protective role in the brain. Studies have shown that many sufferers of dementia do in fact have lower than normal levels of testosterone. 

A study by Hogervosrt et al showed that the link between the two was so strong that they could be classed as co-morbidities.

One interesting point is that there is no link between dementia in females and testosterone levels.

Low Levels of Free testosterone have also been linked with the presence of Aβ40 protein which is a strong indicator of dementia.

To Sum Up

There is no doubt that testosterone is key to us having good muscle tone, strength and energy. It is also responsible for our sex drive and performance. 

What these studies have shown is that testosterone levels can also be linked to cognitive functions, spacial awareness, memory and concentration.

Low T has also been linked to cognitive illnesses such as dementia.

With these facts in mind, its absolutely crucial to boost and maintain your precious testosterone levels through regular exercise, healthy nutrition and a good natural Testosterone booster.
