How Exercise Boosts Brain Function ...
Exercise is one of the best gifts you can give to your brain
It helps in increasing your concentration and attention span. It also helps with attention deficit disorder (ADD/ADHD)
Exercise can be boring, and it takes a lot of time. What's more, it can be difficult to do, especially as one grows older. But I know that exercise is one of the best gifts I can give to my body. In fact, exercise is the best gift I can give to my brain too, especially if I want to increase my concentration and attention span; and especially if I have an ADHD/ ADD brain.
We all know that physical activity is great for the body. But exercise also increases blood flow to the brain, stimulating the release of compounds that the brain just loves, including growth factors and a substance known as brain-derived neurotropic factor (BDNF), which promotes growth of new brain cells (neurons). These substances keep the brain operating at peak efficiency.
Scientists have been studying the psychological benefits of exercise for decades. They have reported scientific evidence to show that regular exercise is a natural antidepressant and anti-anxiety agent. They assert that prolonged, strenuous workouts raise bloodstream levels of endorphins, the naturally occurring opiates that diminish pain while boosting feelings of well-being – walking, for example, can be enough to boost levels of the neurotransmitter dopamine, which regulates our sensations of reward, motivation, and attention.
Physical activities that involve coordination and complex movements - such as martial arts, dance, and basketball - cause connections to form between neurons in the cerebellum. That's the region of the brain that controls, among other things, our social interactions.
What does this mean for people with short attention spans and for those who lack concentration, and for those who suffer of ADHD/ADD? It means that we must think of exercise as an essential component of treatment - something that makes it easier to sustain mental focus for extended periods of time. Would you skip a trip to your doctor just because you had a tight schedule? Of course not. You shouldn't skip exercise either.
If your child has short attention spans or has problems concentrating on tasks, or suffers ADHD/ADD, make sure his school doesn't discipline him by keeping him inside during recess or forcing him to sit in detention. When your child misbehaves, his penalty should involve something that is both productive and physically active.
Finally, make sure that your child isn't banned from athletics because of poor academic performance. Both sports and academics are essential for a child's development. Do schools deny unruly children academic instruction because of poor performance in athletics?
It's best to exercise about 30 minutes a day; and make exercise part of your daily routine
الدماغ عند المعانين من الدسلكسيا The Dyslexic Brain
Does brain anatomy in dyslexics vary by gender?
New research shows that brains of males and females with dyslexia differ significantly. MRI scans of the brains of 118 men, women, boys and girls with and without dyslexia showed less gray matter in areas of the brain that process language in males with dyslexia, while females with dyslexia had less gray matter in areas involved in sensory and motor processing.
Earlier studies showed sex-specific variance in brain anatomy. Females tend to use both hemispheres for language tasks, while males use the left hemisphere only.
هل يختلف تشريح الدماغ في المعانين من الدسلكسيا بين الذكور والإناث؟
أكدت دراسات جديدة أن أدمغة الذكور والإناث ممن يعانون من عسر القراءة تختلف تشريحياً، حيث أثبت المسح الطبقي لأدمغة 118 من الرجال والنساء، والفتيان والفتيات ممن يعانون و ممن لا يعانون من عسر القراءة أن "المادة الرمادية" في الدماغ عند الذكور المعانين من عسر القراءة أقل في مناطق الدماغ المسؤولة عن المعالجات اللغوية، بينما كانت "المادة الرمادية" في الدماغ عند الإناث المعانيات من عسر القراءة أقل في مناطق الدماغ المسؤولة عن المعالجات الحسّية والحركية
وأبرزت الأبحاث السابقة في هذا المجال إختلاف أدمغة الذكور والإناث بوجه عام. فهناك تباين في التشريح الدماغي، حيث تميل الإناث ﻻستخدام كلا نصفي الدماغ للمهام اللغوية، بينما يستخدم الذكور النصف الأيسر فقط
