Stress Can Harm Your Brain and Impair Your Memory

If you are stressed and have noticed that you are finding remembering things is becoming an issue then read more.

Many of our patients complain about having a poor memory. Being young and forgetful doesn’t bother most people, but in older individuals, it’s typical to start worrying if a poor memory is a dementia warning sign.

Several different factors have the ability to compromise your memory; recent research has uncovered another one. Having high blood levels of cortisol can impair your memory. This is according to research published in the Journal of Neuroscience. Cortisol is a well-known stress hormone. It is made by the adrenal glands and released into the bloodstream during emotional or physical stress (examples of physical stress are injuries, surgery or illness).

Short-term elevations in cortisol are necessary and are good for you. They help to make you more alert and better equipped to handle stress or an emergency. The problem is many people have chronically elevated cortisol.

If you have been experiencing long-term stress, or you regularly feel upset or anxious, chances are you have high cortisol. There is a blood test your doctor can arrange to check your cortisol level. The blood test should be performed in the morning (around 7:30 or 8 am) and again in the evening (around 5:30 pm).

Long-term elevated cortisol doesn’t just affect your brain; it increases the risk of abdominal weight gain, high blood pressure, digestive problems and weakened immunity. In people with insulin resistance, it can make the condition worse. Long-term elevated cortisol can also cause you to lose bone density and muscle mass while raising body fat levels and ageing you more quickly.

In this particular study, researchers showed that elevated cortisol caused a loss of synapses in the region of the brain called the prefrontal cortex. Synapses are nerve connections and they allow the brain to process, store and recall information. Long-term elevated cortisol can cause this region of the brain to shrink.

I’m sure you know stress is bad for your health in many ways. Sometimes we are trapped in a difficult situation in life where it’s extremely hard not to feel stressed. Please remember to take time out for relaxation, fun and adequate sleep. It’s very important to give your body time to unwind and de-stress. Meditation, yoga, magnesium and gentle exercise also help to reduce cortisol. Tyrosine is a neurotransmitter that your brain requires in order to produce neurotransmitters.

+++ Tyrosine is an amino acid that is required for the production of important brain chemicals (neurotransmitters). This amino acid is also critical for the production of thyroid hormones in the body. Tyrosine is found in foods high in protein, including these: sesame seeds, cheese, soybeans, meat and poultry, fish and nuts.
