Neuroscience and Neurology exploration

Multiple Sclerosis (MS) is a chronic autoimmune disorder that affects the central nervous system (CNS), which includes the brain and spinal cord. It occurs when the immune system mistakenly attacks the protective covering of nerve fibers, known as myelin , leading to communication problems between the brain and the rest of the body.  The primary way MS disrupts communication in the nervous system is through demyelination . 1. Demyelination: In a healthy nervous system, nerve fibers are covered by a protective sheath called myelin. Myelin acts as an insulating layer, allowing nerve signals to travel quickly and efficiently along the nerve fibers. However, in MS, the immune system mistakenly attacks and damages the myelin, leading to its destruction. This process is known as demyelination. 2. Inflammation: The demyelination process triggers inflammation in the affected areas. Inflammatory cells and molecules further damage the myelin and can also cause damage to the underlyin...

  Dementia is a neurodegenerative disease that has several different forms, symptoms, and causes. Dementia may be caused by a variety of illnesses or injuries. While age remains the most significant risk factor for dementia, research demonstrates that proactive measures can be taken to mitigate personal risk. Engaging in regular physical activity, adopting a healthy diet, and exercising your mind are the key strategies to reduce your risk. What is Dementia? Dementia is a condition where people experience memory loss, have trouble thinking and reasoning, and find it hard to do things on their own at work or in daily life. Certain forms of dementia are progressive, which means they worsen gradually as time goes on. However, some types of dementia are treatable and can even be reversed.  Dementia is more common among older people, which is why it's often seen as a late-life condition. The most common causes of dementia include Degenerative neurological diseases . These are Alzh...

  Left Brain vs. Right Brain The brain is a complex organ that performs several functions. To accomplish all critical biological operations, the two sides of the brain interact with one another. Both the left and right sides of the brain appear to be fairly similar. They do, however, have considerable peculiarities, particularly in information processing. Over the last half-century, there has been a continuous endeavor to solve the enigma of the two hemispheres and how they work. While war aided the process, the severe brain injuries it caused prompted a series of naturalistic studies to investigate the impact of specific brain injuries. Brain Lateralization The topic of brain lateralization has become somewhat controversial in recent years. The term "lateralization of the brain hemispheres" describes the functional dominance of one hemisphere over the other when one hemisphere is more or totally in charge of controlling a function in contrast to the other. While there is ...
