Cerebral Hypoxia

Cerebral hypoxia, or hypoxic brain injury, is a serious condition in which the brain is partially private from oxygen. In the most severe cases, it leases to deep brain injury. Many people make a confusion between anoxic brain injury and hypoxic brain injury, but the two are different conditions. In anoxic brain injury, no oxygen reaches the brain. In such cases, patients are submitted to oxygen and ventilation therapies, to avoid coma and brain death.

Why is this disease developed?

Cerebral hypoxia can be caused by any type of event that leads to brain injury and a lack of oxygen in the brain. Causes can be classified as internal or external to the body. The mild forms of the disease can be caused by asthma or anemia, as well as other diseases that affect blood oxygenation and breathing. However, in most cases, this brain disease is determined by traumatic events.

Cerebral hypoxia may be caused by:

  • Pressure on the windpipe;
  • Strangulation;
  • Chocking;
  • Breathing in smoke;
  • Carbon monoxide poisoning;
  • Drowning;
  • Drug overdose;
  • Very low blood pressure;
  • Cardiac arrhythmia;
  • Diseases that prevent movement.

Signs and symptoms

There are few signs and symptoms that may indicate the development of this condition. They include:

  • Change in attention;
  • Poor judgment;
  • No breathing;
  • Uncoordinated movement;
  • No response of the pupils of the eye to light;
  • Complete unawareness and unresponsiveness.

Treatment

Emergency treatment has to be administrated to patients suffering from brain injury. The sooner the oxygen supply is restored to the brain, the higher chances a patient has to improve his health and avoid severe damage to the brain. Treatment depends on the state of each patient. It will commonly include mechanical ventilation and oxygen, controlling the heart rate, raising blood pressure, in case it is low, as well as medication to prevent and calm seizures.

Rushing the patient to the emergency room as soon as the disease shows its first signs is a must. This may not only help him overcome the disease sooner, but it may actually save his life.

Cerebellar Stroke Syndrome

The cerebellar stroke syndrome is a serious condition in which the circulation of blood to the cerebellum is impaired. This happens due to a lesion formed on the superior cerebellar artery. Commonly, a cerebellar stroke occurs when the blood supply for the brain is interrupted. In the lack of oxygen and nutrients, loss of important functions is experienced by patients. Immediate medical assistance is required when patients suffer from cerebellar stroke.

There are two main types of cerebellar strokes: Ischemic and Hemorrhagic.

Ischemic cerebellar stroke

This is the most common type of cerebellar stroke diagnosed in patients. The stroke can be caused by a sudden decrease in blood flow determined by a series of factors. Some of the most important such factors include the forming of a cloth that breaks off and blocks the flow, but also a tear in an artery that supplies blood to the brain.

There are a series of risk factors that can lead to the development of an cerebellar stroke. They include:

  • High blood pressure;
  • High cholesterol levels;
  • Obesity;
  • Alcohol abuse;
  • Drug abuse;
  • Atherosclerosis;
  • Metabolic syndrome;
  • Type 2 diabetes;
  • Atrial fibrillation;
  • Blood circulation problems.

There are certain lifestyle factors which can increase the risk of cerebellar stroke development. They include smoking, the lack of physical activity, as well as an unhealthy diet.

Symptoms

Preventing as much as possible a cerebellar stroke is a must. However, in case you are suffering from such a serious health problem, you need immediate medical assistance. This is why you need to be careful at all symptoms that may indicate something is wrong with your health and seek medical assistance as soon as possible.

Most common cerebellar stroke symptoms include:

  • Uncoordinated movements of the limbs;
  • Tremor;
  • Abnormal reflexes;
  • Speech problems;
  • Difficulty hearing;
  • Problems with vision and eyes;
  • Nausea and vomiting;
  • Difficulty walking;
  • Intense headache;
  • Loss of consciousness.

If you or someone else is experiencing such symptoms, you need to call an ambulance right away!

There are a series of tests that doctors will perform with the purpose to diagnose this condition. They include a CT scan, CT angiogram, MRO scan, MRA, blood tests, as well as kidney function tests and tests to check heart function. Treatment will vary from one patient to another, depending on his state of health, as well as his medical history. Rehabilitation will commonly be required for patients to improve their health.

Cerebellar Tumors

The cerebellum is the second largest part of the brain. The cerebellum is located in the back of the skull, above the brain stem. This part of the brain is responsible with posture, balance, as well as equilibrium. The cerebellum controls movements, walking and talking. Some of the most serious conditions that can affect the cerebellum are tumors. Tumors located in the cerebellum interfere with normal functions, causing a wide range of symptoms.

Symptoms of cerebellar tumors

The symptoms experienced by patients who have a cerebellar tumor will vary depending on the size, location, but also the type of the tumor. The speed at which the brain tumor is growing may also be an important factor in determining symptoms. However, what patients should know is that being careful at such symptoms and scheduling a doctor’s appointment in time may actually make the difference between life and death. Regardless of the type or location of these tumors, they have to be removed.

Below you can find a list of the most common symptoms that patients will experience.

  • Headaches;
  • Nausea;
  • Dizziness;
  • Difficulty with coordination and balance;
  • Confusion;
  • Disorientation;
  • Vision loss;
  • Speech difficulty;
  • Behavior changes;
  • Impaired memory.

Many of these symptoms can be associated with a wide range of other diseases. This is why, as soon as you feel that there may be something wrong with your health, you should seek medical assistance.

Types

There are two main types of cerebellar tumors: primary and secondary tumors. They can be benign or malignant. Primary tumors are the tumors that originate in the cerebellum. On the other hand, secondary tumors are the ones that spread from other parts of the body and affect the cerebellum.

Medulloblastoma is one of the most serious types of tumors that originates in the cerebellum. This is a fast growing type of brain tumor, summing about 20 percent of all brain tumors found in both children and adults. Still, children are more affected by this tumor than adults. However, you should know that there are many other types of tumors that can be traced in the cerebellum. Cerebellar astrocytoma is another primary type of tumor located in the cerebellum.

Diagnosis

In case you feel that something can be wrong with your health, schedule an appointment with your doctor. The physician will ask you about your symptoms and in case he has reasons to suspect that you may suffer from a cerebellar condition, you will be referred to a neurologist. This specialist will test reflexes, as well as hearing and vision. A magnetic resonance imaging test, as well as a computerized tomography may be recommended to confirm the suspicion in the diagnosing process. Additional tests may be performed with the purpose to measure the tumor’s activity, as well as to determine if it is cancerous or not.

Treatment

In most cases, specialists are going to recommend the surgical removal of the tumor found in the cerebellum. In case the tumor has started to spread, it can only be partially removal or may cause additional damage to the body, radiation and chemotherapy can also be recommended.

Treating tumors in the cerebellum is extremely difficult. Even though people can overcome such conditions, these tumors cause numerous deaths, too, as they can be traced in highly advanced stages. This is why seeking medical assistance immediately after realizing that something may not be in order with your health is mandatory.
