IQ and Intelligence

As clinical neurology experts, we are here to dispel some common myths about the human brain. One of the most prevalent misconceptions is that we only use 10% of our brains. This is simply not true. In fact, the size of the brain does not necessarily determine intelligence. While some creatures may have larger brains than humans, their brains may not be as complex. Additionally, non-cognitive factors such as social and emotional intelligence also play a role in determining intelligence. IQ tests are not always an accurate measure of intelligence, as there are many different types of intelligence that cannot be measured by these tests. As neurology professionals, we encourage everyone to continue learning about the complexities of the human brain and to not believe in common myths. The transmission of information from your eyes to your body is processed in a way that makes sense. Additionally, if we examine the brain, we can identify different parts with specific functions. One such part is the brain stem, often referred to as the lizard brain, which controls basic functions like arousal levels, breathing, heart rate, and blood pressure. It also houses certain motor functions. Another important part of the brain is the cerebellum, located at the bottom, which is involved in motor control and planning. While performing a task, multiple parts of the brain may be utilized, but not all at once. Contrary to the belief that video games deteriorate the brain, this is actually a myth. Research has shown that video games, especially those focused on teamwork, problem-solving, puzzle-solving, and strategic thinking, can be beneficial. They help develop and strengthen various areas of the brain, particularly in children. Video games are also used in surgical training to practice skills through simulators. The amount of time spent playing video games is subjective, as there is no defined limit. However, excessive withdrawal from social activities and a preference for gaming over other pursuits may indicate a problem. It is important to maintain a balanced approach and not let gaming negatively impact one's social life. Contrary to popular belief, memory does not necessarily decline with age. In fact, certain types of memory, such as semantic memory, can improve as one gets older.

All the factors that can lead to a stroke are well understood. It is clear that conditions such as high blood pressure, smoking, high cholesterol, and diabetes can unfortunately increase the risk of a stroke. A stroke occurs when there is a disruption in blood flow to the brain due to either a blood clot or bleeding. There is no quick and easy solution to this problem. The key is to consistently maintain cardiovascular and brain health over time to prevent the occurrence of a stroke. If you ever experience symptoms of a stroke, it is important to remember the FAST mnemonic: Facial droop, Arm weakness, Slurred speech or language problems, and Time to call 9-1-1 and seek immediate medical attention at a hospital. Emergency medicine physicians can administer clot-busting medications to dissolve the clot causing the stroke, thereby addressing the issue and preventing further damage. It is a common misconception that strokes only affect older individuals. In reality, strokes can occur at any age, although the causes may differ between younger and older individuals. Brain bleeds are a significant cause of stroke in young people, particularly those with a family history of aneurysms. It is recommended for such individuals to undergo screening. As for the belief that eating fish makes you smarter, it is unclear where this notion originated. While fish is indeed beneficial for overall health, certain types of fish, particularly those high in omega-3 fatty acids, are known to promote heart and brain health. However, it is important to consume fish in moderation, as some varieties, like tuna, may contain higher levels of mercury.

In essence, a seizure occurs when all of your neurons fire at once, causing your body to hyper synchronize. Seizures can be caused by a variety of factors, not just epilepsy, which is a lifelong neurological condition that requires daily medication to prevent seizures. It's important to see a neurologist and undergo tests such as an EEG or MRI to determine the cause of your seizures. If epilepsy is diagnosed, taking medication and maintaining open communication with your doctor is crucial for achieving seizure freedom. Remember, you only have one brain, so it's important to take care of it and do your research to dispel any myths surrounding seizures.
