It is a growth of abnormal cells within the brain which may be cancerous or non cancerous. Most are discovered in people ages 35 to 60. Women are slightly more likely to develop an aneurysm than men are. Human consciousness involves both the extended capacity of the modern neocortex in particular as well as profoundly developed prototypical structures of the brain stem . But the human brain is unique, in part, because it relies on some million billion synaptic connections, making it an extremely intricate and densely connected neural
Brain tumors produce symptoms by compression of adjacent tissues or by infiltrative spread. Many of the symptoms are caused by the expansion of tumors within a fixed bony vault. The nature and severity of these symptoms depend upon the location of the tumor and the rate of its growth. Masses greater than 3 cms in diameter compress brain and its blood supply.
The human brain is the anteriormost part of the central nervous system in humans as well as the primary control center for the peripheral nervous system . Also known as a cerebral aneurysm, the bulge may pose little risk to your health — as long as it's small and it doesn't rupture. When you buy a home, you consider its location and condition so that your investment is safe. Falls around the home are the leading cause of injury for infants, toddlers, and elderly people. Violent shaking of an infant or toddler is another significant cause. The brain also controls "higher" order, conscious activities, such as thought , reasoning , and abstraction . Singular among those of all animals , the human brain possesses the largest and most massive neocortex. Humans thus enjoy unique neural capacities despite the fact that much of the human neuroarchitecture resembles that of more primitive species . Here you can get to know your brain – the food it likes, the challenges it craves, the rest it requires, the protection it deserves. About 10 percent of the surviving individuals have mild to moderate problems that threaten their ability to live independently. People of all ages can have a brain aneurysm, but most develop as a result of aging. network .
There are many different types of brain tumour. However, some brain aneurysms are large enough to put pressure on surrounding brain tissue. Some, such as a meningioma that forms from the meninges or covering of the brain, are almost always benign and removed easily by surgery. Others may rupture at a weak spot in the artery wall, flooding an area of your brain with blood (hemorrhage). Young children and individuals over 75 years of age are also more susceptible to head injury. Falls around the home are the leading cause of injury for infants, toddlers, and elderly people The fibers transmitting signals to the brain are called afferent (or sensory) fibs. Nerves can be afferent, efferent or mixed (i.e., containing both types of fibers). The brain is also responsible for control of posture and movements . The brain can perform a variety of functions automatically, without the need for conscious awareness, such as coordination of sensory systems (eg. sensory gating and multisensory integration ), walking , and homeostatic body functions such as heart rate , blood pressure, fluid balance, and body temperature.Small aneurysms are often best left alone, though treatments are available for larger aneurysms.
Causes of Brain -Tumour
The common Causes of Brain -Tumour :
- A traumatic brain injury occurs when an outside force impacts the head hard enough to cause the brain to move within the skull or if the force causes the skull to break and directly hurts the brain.
- Primary brain tumors originate in the brain or close to it, such as in the skull, brain membranes (meninges), cranial nerves, pituitary gland or pineal gland. Most brain tumors in children are primary.
- Secondary (metastatic) brain tumors are tumors that result from cancer that starts elsewhere in your body and then spreads (metastasizes) to your brain cancers of the lung and breast are most likely to spread to your brain.
Symptoms of Brain -Tumour
Some common Symptoms of Brain -Tumour :
- Nausea and vomiting
- Weakness or loss of feeling in the arms or legs
- Stiff neck or neck pain
- Stumbling or lack of coordination in walking (ataxic gait)
- Slow, sluggish, lethargic movement
- Blurred vision or double vision
- Pain above and behind the eye
- Abnormal eye movements or changes in vision
Treatment of Brain -Tumour
Here is the list of the methods for treating Brain -Tumour :
- The use of high-dose X-rays to kill cancer cells and shrink tumors radiation therapy for childhood brain tumors usually comes from a machine and is called external radiation therapy.
- The three most commonly used treatments are surgery, radiation, and chemotherapy.
- Doctors also may prescribe steroids to reduce the swelling inside the CNS.
- High-energy radiation can be used to destroy tumor cells in your brain.
- If surgery is not feasible because of the location or size of the aneurysm or the condition of the person, medical treatment is similar to treatment for subarachnoid hemorrhage
- These drugs, taken by mouth or intravenously, can help kill cancerous tumor cells.
- Chemotherapy, radiation, and surgery can all be part of the treatment for mesothelioma combined approaches that utilize these therapies together, particularly using chemotherapy prior to surgery, as well as new drugs that specifically target mesothelioma cells, are currently being tested.
