Studies say strong muscles can provide better brain health

Anyone who believes that bodybuilding only brings aesthetic benefits is wrong. Strengthening muscles also contributes to the formation of new neurons and helps in brain development, according to recent studies. Different research indicates that keeping muscle active and an exercise routine collaborates with brain health, and helps, for example, in the prevention of cognitive losses.

According to the MIT Technology Review, a portal specializing in technology, scientists have shown that some myokines (signaling molecules, which tell other parts of the body what they should do) participate in the control of brain functions, such as learning, memory and mood.

In addition, they can also act as mediators and trigger beneficial processes in the brain as a result of physical exercise, such as the formation of new neurons. Other research with myokines showed neuroprotective effects against ischemic injuries and neurodegenerative diseases, including Alzheimer’s.

Evidence indicates that being physically active reduces the risk of dementia and slows cognitive decline in adults who are older or who already have existing brain disease and damage.

Another study, published by the US National Institute on Aging, revealed that exercise encourages the brain to maintain old network connections and make new ones that are vital for cognitive health. In addition, scientists believe that aerobic exercise, such as walking, is more beneficial to the brain than non-aerobic, stretching and toning exercises.

Other signs that may indicate neurodegenerative diseases are: lack of interest in usual activities, difficulty in performing day-to-day tasks, repeating conversations or tasks, disorientation in familiar places and difficulty in memorization.

Parkinson’s, Alzheimer’s and dementia are neurodegenerative diseases that mainly affect the elderly population. The conditions are progressive and, over time, the patient becomes more dependent on the care of others.

It is common that, in the initial stage, the symptoms are confused with the natural aging process. However, family members and close people should be aware of the signs.

It is also important to seek help from doctors, because the earlier the diagnosis, the greater the chances of controlling the case and delaying the progression of diseases, as well as increasing the quality of life of patients.

Parkinson’s causes the death of neurons that produce dopamine and play an important role in the locomotor system. Men are the most affected.

The patient’s family members should be aware of the first signs of sluggishness, muscle stiffness and frequent tremors, which are more characteristic of this condition.

Alzheimer’s, in turn, affects more the female population. It causes the degeneration and death of neurons, which results in the progressive alteration of brain functions.

The most recurrent consequences are the impairment of memory, behavior, thinking and learning ability.

Dementia is progressive and the initial symptoms are well known: memory loss and confusion are the most common. The condition affects up to 25% of people over 85 years of age in Brazil.

Speech problems and difficulty making decisions are also among the signs. However, there are other subtle signs that can alert to the development of some types of degenerative diseases.

Vision problems: A study done in the UK by UK Biobank shows that people with age-related macular degeneration are 25% more likely to have dementia.

Hearing loss: May be linked to cellular changes in the brain. But vision and hearing loss can lead to social isolation, which has been known for years as a risk factor for Alzheimer’s and other forms of dementia.

Mood swings: People with early dementia stop finding jokes funny or don’t understand situations they used to find amusing and may have difficulty understanding sarcasm.

Gum problems: Research shows that oral health is linked to mental problems and may also be linked to type 2 diabetes, high blood pressure, high cholesterol, obesity and alcoholism — all of which are also risk factors for dementia.

Social isolation: the symptom can increase the risk of neurodegenerative diseases. A lack of patience with friends and family and a preference for being alone can be signs of chemical brain problems or lack of vitamins.

Other signs that may indicate neurodegenerative diseases are: lack of interest in usual activities, difficulty in performing day-to-day tasks, repeating conversations or tasks, disorientation in familiar places and difficulty in memorization.

Parkinson’s, Alzheimer’s and dementia are neurodegenerative diseases that mainly affect the elderly population. The conditions are progressive and, over time, the patient becomes more dependent on the care of others.

They also found that anaerobic training (of high intensity and short duration) increases the size of the hippocampus, improving spatial memory, which is responsible for recording information about the surroundings and locations.
