High Blood Pressure and Brain Damage

High Blood Pressure and Brain Damage

Stroke, Dementia, Mild Coginitive Impaiment and Tran Ischemic attack are few of problems resulting due to high blood pressure.

What is Stroke?

A stroke happens when a part of the brain does not get proper supply of oxygen and the brain cells start to die.

High Blood Pressure causes stroke due to formation  of  blood clots leading in the arteries  which block off blood supply.

High blood pressure over a period of time, also causes the arteries to weaken , narrow and potentially rupture over a period of time.

What is Dementia?

A dementia is a state before alzheimer where a patient tends to start forgetting things, In Vascular dementia the culprit is often a stroke.

Dementia and mild cognitive impairment both result from lack and interruption of blood supply to the brain when high blood pressure damages arteries over time.

Transient Ischemic attack or a mini stroke is a brief disruption in the blood supply caused by a blood clot. A mini stroke is a warning sign that a full blown stroke is on it way.

Consult if your loved ones suffers from Stroke, Dementia , Mild Coginitive Impaiment and Tran Ischemic attack.

Other Rare Brain Tumors

There are some other rare Brain tumors including Choroid Plexus Tumors, papillomas and carcinomas, in infants. These tumors primarily treated with surgical resection and occasionally chemotherapy.

Craniopharyngiomas are treated by surgical resection and radiation therapy based on the location of the tumor and involvement of the surrounding tissues.

These Brain sarcomas are treated with maximal surgery, local radiation and chemotherapy appropriate for body sarcomas.

Brain Tumor Symptoms :

Signs and Symptoms of Brain Tumor are as frequent headaches, especially after waking up in the morning, vomiting, especially in the morning, Eye movement problems and/or vision changes, Unsteady gait or worsening balance, Weakness of one side of the face, Loss of previously acquired developmental milestones, Weakness in the arms or legs, Bulging fontanel (soft spot on an infant’s head where the bones that make up the skull have not fully joined) or increased head size in infants, Tilting of the head or neck to one side, Seizures, Difficulty with speech, swallowing or drooling, Back or neck pain, often waking the child at night.

Less common symptoms include: Changes in eating or thirst, Growth problems, Dizziness, Lethargy, irritability or other behavior changes, Deterioration in school performance, Loss of sensation in the arms or legs, Loss of consciousness, without history of injury, changes in, or loss of control of, bowel or bladder, Hearing loss, without evidence of infection

Treatment for Brain Tumors:

Treatment for rare brain tumors often includes surgical removing as much of the tumor as possible, but It also include Radiation therapy and Hormone replacement therapy (HRT).

Spinal Cord Tumors Types, Treatment

Spinal cord tumors are of several types including:

Ependymomas, and low- and high-grade Astrocytomas.

Treatment Spinal cord tumors:

Treatment often includes removing as much of the tumor as possible without further damaging the spinal nerves.

For low-grade tumors, some children also receive outpatient chemotherapy similar to that which is used for low-grade astrocytomas.

For high-grade spinal cord tumors, children are generally treated with chemotherapy and radiation to the tumor.

Brain Tumors and Central Nervous System Tumors, Medulloblastoma

Brain tumors occur in the central nervous system (CNS) and spinal cord in children. These important organs, CNS and spinal cord work together to control functions necessary to sustain life, such as breathing, heart rate, movement, thinking and learning.

Brain produce important substances and chemical mediators which stimulate and control many other organs in the body. In general, brain tumors tend not to “metastasize” or spread to distant areas of the body outside the brain or spinal cord.

They can recur locally, and they can spread to other areas of the central nervous system. Collectively, they comprise nearly 20% of childhood cancers diagnoses.

There are several different types of brain tumors, description is as following.

Medulloblastoma
Medulloblastoma is the most common malignant brain tumor in children. It is a fast growing tumor that begins in the lower back part of the brain (the posterior fossa) and can spread to other parts of the body. In up to one-third of patients, the tumor would have been spread along brain lining (meninges) and spinal cord at the time of diagnosis.

Signs and Symptoms of Medulloblastoma:

Signs and Symptoms are associated with vomiting, headache and balance problems

Medulloblastoma Treatment:

The main types of treatment for Medulloblastoma are:

  • Chemotherapy
  • Immunotherapy
  • Targeted therapy
  • Radiation
  • Stem cell transplant
  • Bone marrow transplant and
  • Surgery.
