Stroke

What is Neuro Stroke? Neuro stroke, also known as a cerebrovascular accident (CVA) or simply a stroke, is a medical condition in which poor blood flow to the brain results in cell death. There are two main types of stroke: ischemic, due to lack of blood flow, and hemorrhagic, due to bleeding. Both cause parts of the brain to stop functioning properly. Signs and symptoms of a stroke may include an inability to move or feel on one side of the body, problems understanding or speaking, dizziness, or loss of vision to one side. Signs and symptoms often begin suddenly, and may progress over hours or days. Types of Neuro Stroke: 1. Ischemic Stroke  This occurs when a blood vessel supplying blood to the brain is obstructed. It accounts for about 87% of all strokes. 2. Hemorrhagic Stroke  This occurs when a weakened blood vessel ruptures and bleeds into the surrounding brain. The blood accumulates and compresses the surrounding brain tissue. Diagnosis of Neuro Stroke: 1. Physical Exami...

Multiple sclerosis

Multiple sclerosis (MS) is a chronic, unpredictable disease of the central nervous system that disrupts the flow of information within the brain and between the brain and body. It's an autoimmune condition where the body's immune system attacks myelin, the protective sheath that covers nerve fibers, causing communication problems between your brain and the rest of your body. Here's a comprehensive tutorial on multiple sclerosis: 1. What is Multiple Sclerosis?     MS is a disease that affects the brain and spinal cord, causing a wide range of potential symptoms, including problems with vision, arm or leg movement, sensation or balance. It's a lifelong condition that can sometimes cause serious disability, although it can sometimes be mild. 2. Symptoms of Multiple Sclerosis     The symptoms of MS vary widely and depend on the amount of nerve damage and which nerves are affected. Some people with severe MS may lose the ability to walk independently or at all, while othe...

Neuralink History

Neuralink, founded by Elon Musk in 2016, has been at the forefront of developing brain-computer interface (BCI) technology, aiming to create a seamless connection between the human brain and computers. The company's journey has been marked by significant milestones, challenges, and breakthroughs. In 2019, Neuralink introduced its first prototype, a device that could record and stimulate brain activity. This was followed by the development of a robot capable of performing the delicate surgery required for implanting the device. The robot's design was a collaboration between Neuralink and Woke Studios, showcasing the company's commitment to innovation. In January 2024, Neuralink achieved a major milestone when it announced the successful implantation of its brain-computer interface in a human subject. This marked the beginning of a new era in BCI technology, as the device allowed the subject to control a computer mouse using their thoughts. The company has since continue...
