Abstract Brain tumours are intricate medical conditions characterized by abnormal cell growth within the brain or its surrounding tissues. These tumours vary widely in terms of type, origin, and malignancy, presenting unique challenges for diagnosis, treatment, and management. This article provides a thorough overview of brain tumours, including their classification, symptoms, diagnostic methods, and treatment options. It also explores recent advancements in research and future directions. By examining these aspects, the article aims to offer a deeper understanding of brain tumours and the ongoing efforts to improve patient outcomes and therapeutic approaches. Keywords: Brain tumour • Malignant • Benign • Glioblastom • Diagnosis • Treatment • Research • Neuro-oncology Introduction Brain tumours are a significant health concern, affecting thousands of people globally each year. These tumours can originate from brain cells or metastasize from other body parts, leading to diverse and often severe symptoms. The complexity of brain tumours necessitates a multifaceted approach to diagnosis and treatment. Understanding the different types of brain tumours, their symptoms, and the latest treatment strategies is crucial for effective management and improving patient quality of life. Types of brain tumours Brain tumours are broadly categorized into benign (non-cancerous) and malignant (cancerous) types. The classification depends on the tumour's origin, growth rate, and potential to spread. Benign brain tumours: • Meningiomas: Arising from the meninges, the protective membranes surrounding the brain and spinal cord, meningiomas are often slow-growing. While they may not be immediately lifethreatening, their size can cause significant neurological symptoms if they press on the brain or spinal cord. • Acoustic neuromas (Vestibular schwannomas): These tumours develop on the vestibulocochlear nerve, responsible for hearing and balance. Symptoms typically include progressive hearing loss, tinnitus, and balance issues. They are usually slow-growing but can cause serious complications if not treated. • Pituitary adenomas: Originating from the pituitary gland, these tumours affect hormone production, leading to a range of symptoms including abnormal growth patterns, menstrual irregularities, and visual disturbances. Malignant brain tumours: • Glioblastomas: These are the most aggressive and common primary brain tumours. Glioblastomas are characterized by rapid growth and resistance to conventional treatments. They originate from glial cells, which support and protect neurons. • Astrocytomas: These tumours originate from astrocytes, starshaped brain cells. They are graded based on their malignancy, with low-grade astrocytomas being less aggressive and high-grade forms, such as glioblastomas, being highly aggressive. • Oligodendrogliomas: Arising from oligodendrocytes, these tumours can be less common but often respond better to treatment compared to other malignant brain tumours. Their treatment and prognosis can vary based on genetic and molecular characteristics. Symptoms of brain tumours The symptoms of brain tumours are diverse and depend on the tumour's type, size, and location. Common symptoms include: • Headaches: Persistent or severe headaches that may worsen over time. • Seizures: New or unusual seizures can be a sign of a brain tumour. • Nausea and vomiting: Often related to increased intracranial pressure. • Cognitive changes: Difficulty with memory, concentration, or language. • Motor and sensory deficits: Weakness, numbness, or difficulty with coordination. • Visual and auditory disturbances: Changes in vision or hearing, often depending on the tumour’s location. Given the overlap of these symptoms with other conditions, accurate diagnosis requires comprehensive evaluation. Diagnostic methods Diagnosing brain tumours involves a combination of clinical evaluation and advanced imaging techniques: Journal Of Multiple Sclerosis 2024, Vol. 11, Issue 4,001-002 2 • Neurological examination: A thorough assessment by a neurologist to evaluate cognitive functions, motor skills, and sensory perception. Imaging tests: • MRI (Magnetic Resonance Imaging): Provides detailed images of brain structures and is crucial for identifying and characterizing brain tumours. • CT (Computed Tomography) scan: Often used for initial imaging and to detect any significant abnormalities. • Biopsy: To confirm the diagnosis, a sample of the tumour tissue is examined microscopically. This can be done through surgical resection or a needle biopsy, depending on the tumour’s location and accessibility. • Surgery: The primary goal is to remove as much of the tumour as possible while preserving surrounding brain tissue. Surgical approaches vary based on the tumour’s location and accessibility. • Radiation therapy: Uses high-energy rays to target and destroy tumour cells. It is often used when complete surgical removal is not feasible or for tumours that are resistant to other treatments. • Immunotherapy: An emerging treatment that uses the body’s immune system to attack tumour cells. While still largely experimental for brain tumours, it holds promise for future treatments. Improved imaging techniques: Innovations in imaging, such as functional MRI and advanced PET scans, are enhancing the ability to detect and monitor brain tumours more accurately. Novel therapeutic agents: Researchers are exploring new drugs and treatment combinations to improve patient outcomes. Clinical trials are essential for testing the safety and efficacy of these new treatments. Patient support and rehabilitation: Comprehensive care includes addressing the psychological and functional impacts of brain tumours. Support services, including counseling and rehabilitation, play a critical role in improving the quality of life for patients and their families. Conclusion Brain tumours are a complex and diverse group of conditions that present significant challenges for diagnosis and treatment. From benign to malignant forms, the variety in tumour types and their effects on neurological function necessitate a comprehensive and individualized approach to management. Advances in research, technology, and treatment strategies offer hope for better outcomes and improved quality of life for patients. Understanding the intricate details of brain tumours and staying informed about ongoing research developments are crucial for optimizing care and advancing the fight against these formidable conditions. As the field of neuro-oncology progresses, there is optimism for more effective therapies and a deeper understanding of brain tumour biology, ultimately leading to enhanced patient outcomes and survival rates
