Brain disorders, including stroke, dementia, meningitis, and epilepsy, are major causes of disability and the second leading cause of death worldwide. That’s why there has been a tremendous amount of research focused on studying this vital organ. Neuroscience is a field that has been developing at a rapid pace lately.
The History of World Brain Day
The idea of dedicating a day to brain health was proposed by the World Federation of Neurology (WFN). It was on July 22, 1957, that this organization was founded, bringing together over a hundred neurological associations worldwide. The Federation has become one of the leading advocates for neurology and brain research.
This year’s theme: “Brain Health and Disability: Leave No One Behind.”
Individuals with disabilities have so many odds stacked against them. We selected this year’s theme to bring attention to the large number of people suffering from neurological disability worldwide.

Facts about the Brain
It is the most complex organ in our body, consisting of about 75% water. That’s why maintaining proper hydration is crucial for its function. It contains approximately one hundred billion neurons, connected by trillions of synapses. It’s an intricate yet delicate structure, although entirely incapable of feeling pain.
Other Fascinating Facts
- The brain is a power-hungry organ, accounting for about 20% of the body’s total energy consumption, despite comprising only 2% of its weight;
- The memory capacity is virtually limitless. It is estimated to be able to store about 2.5 petabytes of information, which is equivalent to three million hours of television shows;
- Damaged neurons can regenerate at approximately one inch per month. Your brain is constantly reshaping itself through a process called neuroplasticity. It can form new neural connections and reorganize existing ones based on experiences and learning. And it’s possible at any age. The process of forming these connections acts as a preventive measure against neurological disorders. Simply put, acquiring diverse new skills can help prevent dementia and Alzheimer’s;
- Around 25% of the cholesterol in our body is found in and even produced by the brain. Cholesterol is essential for the proper functioning of serotonin receptors. Low cholesterol levels have been linked to depression, aggressive behavior, and a tendency towards suicide, particularly among older individuals;
- Basically, fatty acids are crucial for our mental well-being. Therefore, a low-fat diet is not beneficial for your cognitive abilities;
- The frontal lobe or cortex, responsible for decision-making and complex problem-solving, continues to develop well into a person’s mid-20s, explaining some of the typical traits associated with adolescence. People with damage to the frontal cortex may lose control over their social behavior;
- The notion that we only use 10% of our brain is a myth. In reality, we use more, even during sleep. We engage our entire brain capacity most of the time;
- Sleep is essential for brain health, as it plays a crucial role in memory consolidation and cognitive functions. During sleep, the brain undergoes essential repair and detoxification processes;
- Physical exercise has a profound impact on the mental health. It increases blood flow, promotes the release of beneficial neurochemicals, and can enhance cognitive functions;
- Stress can negatively affect the brain by impairing memory and decision-making abilities. Chronic stress can even lead to structural changes, potentially increasing the risk of mental health disorders.
