Cerebral ischemia is a condition in which there is a lack of blood flow to the brain, leading to a decrease in oxygen and nutrient supply to brain cells. This can result from a blockage in the blood vessels supplying the brain, such as a blood clot or plaque buildup, or from a decrease in blood flow due to other factors like low blood pressure. Cerebral ischemia can lead to brain damage and neurological deficits if not promptly treated. Common symptoms include sudden weakness, numbness, or paralysis on one side of the body, difficulty speaking, and vision problems. **

Infantile cerebral palsy is considered a severe disability as it can significantly impact a child's motor function, coordination, and muscle control. It can also affect speech, vision, and cognitive abilities. Individuals with infantile cerebral palsy may require ongoing therapy, assistive devices, and support to manage their condition and participate in daily activities. The severity of the disability can vary depending on the individual and the extent of their condition. **

Severe anxiety after a cerebral thrombosis can be caused by a variety of factors. The sudden and unexpected nature of the event can lead to feelings of fear and uncertainty about the future. Physical and cognitive changes resulting from the thrombosis, such as difficulty speaking or moving, can also contribute to anxiety. Additionally, the potential for future strokes or complications may increase anxiety levels in individuals who have experienced a cerebral thrombosis. **

Intense fear after a cerebral thrombosis can be caused by a variety of factors. The sudden and unexpected nature of the event can lead to feelings of vulnerability and anxiety. Additionally, the physical and cognitive changes that can result from a cerebral thrombosis, such as difficulty speaking or moving, can be frightening and disorienting. The fear of experiencing another stroke or the fear of long-term disability can also contribute to intense fear after a cerebral thrombosis. Finally, the emotional impact of facing mortality and the uncertainty of the future can also lead to intense fear. **

Stock dividends are additional shares of a company's stock that are distributed to existing shareholders as a form of dividend payment. Instead of receiving cash, shareholders receive more shares of the company's stock. This can be a way for a company to reward its shareholders without using cash, and it can also help to increase the number of shares outstanding. Stock dividends are typically expressed as a percentage, such as a 5% stock dividend, which means that for every 100 shares owned, the shareholder would receive an additional 5 shares. **

Yes, infantile cerebral palsy can be considered a severe disability. Cerebral palsy is a group of disorders that affect a person's ability to move and maintain balance and posture. Infantile cerebral palsy specifically refers to the condition that develops in infancy or early childhood. Depending on the severity of the condition, it can significantly impact a person's mobility, coordination, and daily functioning, making it a severe disability for some individuals. **

With the accessibility of low-cost investment platforms and fractional shares, it is easier than ever to start investing with small amounts of money. However, it's important to do thorough research and consider the potential risks before investing. **

The cerebral cortex has an enlarged surface area to accommodate a greater number of neurons and synapses, allowing for more complex cognitive functions. This increased surface area also enables more efficient communication between different regions of the brain, enhancing information processing and integration. The folding of the cerebral cortex into gyri and sulci further increases its surface area within the limited space of the skull, maximizing its capacity for higher-order thinking and decision-making. **
