An arteriovenous malformation (AVM) is an abnormal tangle of blood vessels that can develop in various parts of the body, most commonly in the brain and spinal cord. This condition involves a complex network of arteries and veins that are interconnected without the usual capillaries in between. AVMs can disrupt normal blood flow and pressure, potentially causing bleeding, reduced oxygen supply to surrounding tissues, and other neurological symptoms. While some AVMs may remain asymptomatic and go unnoticed, others can lead to serious health issues, including seizures, headaches, neurological deficits, or, in severe cases, hemorrhagic strokes. Treatment options for AVMs vary depending on their size, location, and the risk of complications. Management may involve surgical removal, embolization (blocking the abnormal vessels), or radiation therapy to reduce the risk of bleeding or alleviate symptoms. Early diagnosis and appropriate intervention are crucial to prevent potentially life-threatening complications associated with arteriovenous malformations.

In this comprehensive article, we will delve into AVM, exploring its types, causes, risk factors, symptoms, prevention, diagnosis and evaluation, treatment and management, and when to seek medical attention.

Arthritis is a broad term that describes more than 100 different inflammatory joint disorders that cause pain, stiffness, swelling, and decreased mobility in one or more joints.

Astigmatism is a common refractive error of the eye that affects the way light enters the eye, causing blurred or distorted vision. Unlike conditions such as nearsightedness or farsightedness, which result from irregularities in the shape of the eye's lens or cornea, astigmatism occurs when the cornea or lens has an irregular shape, resembling more of a football than a spherical shape. This irregularity causes light to focus on multiple points in the eye, leading to blurred vision at various distances. Astigmatism can occur in combination with other vision problems and is often present from birth. Eyeglasses or contact lenses can effectively correct astigmatism by compensating for the irregular curvature of the eye's lens or cornea, allowing light to be properly focused on the retina. For those seeking a more permanent solution, refractive surgery like LASIK can also be an option to reshape the cornea and alleviate astigmatism. Regular eye exams are essential for diagnosing and managing astigmatism to ensure clear and comfortable vision.

In this extensive article, we will delve into astigmatism, exploring its types, causes, risk factors, symptoms, prevention strategies, diagnosis and evaluation, treatment and management, and when it's imperative to seek medical advice.
