A tumor is any accumulation caused by unusual or unrestrained growth of cells. Brain tumor is an acute nervous syndrome which necessitates to be healing on correct time. Brain tumors can take place either from the brain itself or the nerves at the bottom of the brain or its coverings or even from outside the brain (it happens when cancer cells go through the bloodstream and lodge in the brain).

There are many types of brain tumors. The most ordinary primary brain tumors are meningiomas, gliomas, vestibular schwannomas, pituitary adenomas, and primitive neuroectodermal tumors.

Brain tumor

The term glioma includes astrocytomas, oligodendrogliomas, ependymomas, and choroid plexus papillomas.

Brain tumors characteristically are labeled as primary or secondary. Primary brain tumors initiate in your brain and can be non-cancerous or cancerous. Secondary brain tumors outcome from cancer, that began somewhere else and multiply to your brain. Primary brain tumors are fewer common than secondary brain tumors. Symptoms may become alert of when a tumor set in shift a nerve or injures a meticulous part in the brain. They are usually takes place when the brain develops or fluids start to make huge amount in the skull region.

There are a lot of symptoms that may build up when a person develops a metastatic brain tumor. These symptoms arrive as a consequence of the fact that tumors have the potential of damage cells in the brain, the tenderness that typically happens with tumors, and the pressure that the tumor may reason as it grows.

Brain hemorrhages are also entitled as cerebral hemorrhage, intracranial hemorrhage or intracerebral hemorrhage. A cerebral hemorrhage is a kind of stroke and is caused by an artery in the brain and root rupture hemorrhage placed

Brain hemorrhage and its causes

in the nearby tissues. This bleeding kills brain cells. When the blood of trauma annoys brain tissue, it causes swelling. This is identified as cerebral edema. In assemble of blood collects into a mass called a hecatomb. These conditions raise the pressure on close by brain tissue and reduced blood flow and vital kills brain cells. The bleeding may happen in the brain between the brain and the membranes that wrap between layers of the covering of the brain or between the skull and the lining of the brain.

There are more than a few risk factors and causes of cerebral hemorrhage. The most well-known are Aneurysm

(This weakening of the blood vessel wall that swells. It can blow up and blood to the brain, which is taken.), Hypertension (This chronic disease over time, deteriorate the blood vessel walls. Untreated hypertension is a main preventable reason of cerebral hemorrhages.), a head injury, (Injuries are the most general cause of bleeding in the brain for less than 50 years.), Vascular anomalies (Weaknesses in blood vessels around the brain and may be there at birth and are analyzed only if symptoms build up.), cerebrovascular amyloidosis (This is an irregularity in the walls of blood vessels that sometimes occurs with age. It can reason many small bleeding overlooked before causing a large company.), blood or bleeding disorders (Hemophilia and sickle cell anemia can both add to lower levels of platelets.), Brain Tumor, Read the rest of this entry »

Parkinson’s disease is a nervous system disorder named after Dr. James Parkinson, a British physician. It was first described by him in the year 1817.

Parkinson’s disease (PD) is caused by gradual death of nerve cells (neurons) in the brain which make ‘dopamine’.  Dopamine is a vital chemical messenger  (neurotransmitter) used by nerve cells to help control movement of muscles. These dopamine producing nerve cells are clustered in a part of brain which is called ‘substantia nigra’ Loss or damage of dopamine producing nerve cells causes reduction in dopamine level. Due to deficiency of dopamine the nerve cells of that part of brain cannot send messages properly and so brain cannot have proper control over movement of muscles.

Parkinson’s disease is a chronic disease and symptoms get worse with time. Both man and woman can get Parkinson’s disease. It is a common disease for elderly. Though it affects persons over age of 50 yet sometimes it affects younger adults also.

Symptoms of Parkinson’s disease

• Trembling: – Trembling in different parts of body like hands, arms, legs, head, jaw etc.
• Stiffness of limbs and trunk.
• Loss of balance/postural instability.
• Slowness in movement (Brady kinesia).
• Difficulty in movement – e.g. difficulty in starting to walk.
• Difficulty in swallowing, eating and chewing.
• Reduction in speech volume.
• Expressionless face.
• Constipation or urinary problem.

Treatment of Parkinson’s Disease

Though there is no cure for Parkinson’s disease (PD) yet some symptoms can be reduced by medications. Varieties of drugs are available these days. The patients of PD are treated with Levodopa in combination with carbidopa. When Levodopa reaches the brain, it can be converted to dopamine by nerve cells. Carbidopa helps to delay the process of conversion of levodopa into dopamine until it reaches the brain.

But this treatment can reduce some symptoms only. In some cases surgery may be needed. When the symptoms of the disease do not respond to drugs then doctors may go for the surgery.
