Hearing Loss/issues & Issues With Balance:

Brain Tumour Related Epilepsy

In brain tumors that affect VIIIth nerve, hearing loss or impairment, tinnitus is common. Hearing loss may be noted by a reduced ability to understand what is being spoken. The hearing loss may be gradual or sudden. If the tumors extend beyond and affect the vestibular system which is responsible for maintaining body balance, one may experience vertigo, dizziness, gait and balance issues . In some cases, the pressure of the infiltrating tumor may also cause facial pain or weakness. A benign tumor called the Acoustic neuroma can also cause similar conditions. Only a complete evaluation from a specialist will be able to diagnose the true nature and cause of the symptom.Besides the above common brain tumor symptoms, patients may experience other less common and vague symptoms such as lactation from breasts, growth spurts in feet or hands inability to look upward . Not all symptoms are representative of brain tumor. Some of these could also be due to benign tumors as well as other conditions or co-morbidities. However, if symptoms persist or worsen, individuals should consult doctors to help find the cause of the problem. If these signs are caused due to brain tumor, besides cancer treatment relieving symptoms is a major goal of treatment.

Who Gets Brain Tumors

Most brain tumors develop in people over the age of 50. If you have a family history of brain tumors or your brain has been exposed to radiation, say, during radiotherapy, you might be at higher risk.

Genetic conditions like neurofibromatosis, Turcot syndrome, tuberous sclerosis, von Hippel-Lindau syndrome, Li-Fraumeni cancer syndrome, and Gorlin syndrome are associated with brain tumors that tend to develop in early adulthood or childhood.

Malignant brain tumors usually seem to develop when cancer from some other part of the body spreads to the brain. And, sometimes, benign brain tumors can also turn malignant.13

Treatments For Brain Tumors In Dogs

Treatment for a brain tumor in dogs will vary based on the type of tumor that is diagnosed. Since brain tumors in dogs can range from cancer to benign tumors, each dog will require their own treatment plan that is tailored to fit their needs.

  • Surgery: In some cases of a benign brain tumor, surgical removal of the tumor can be curative. This will involve the help of a board certified veterinary neurologist that can skillfully remove the brain tumor.
  • Chemotherapy: If the tumor is unable to be surgically removed or is the result of metastasis, chemotherapy may be an option. Chemotherapy can help to shrink the tumor, and possibly reduce symptoms due to the change in size. This will often involve the help of a veterinary specialist, though some standard vet clinics can perform chemotherapy.
  • Radiation: Radiation can also be used to reduce the size of a brain tumor when surgery is not an option, or can be used after surgery to take care of any tissue that has been left behind. If your dog does require radiation to treat their brain tumor, they will need to seek the help of an experienced radiation therapist.
  • Medical Management: Some dogs may benefit from the addition of daily medication. Dogs with brain tumors may require steroids to decrease the severity of symptoms, as well as anti-seizure medications to control their seizure activity.

How Are Epilepsy And Brain Tumors Treated

Everybody’s treatment pathway is different depending on the kind of tumor you have as well as the kinds of seizures you are experiencing.

But, speaking broadly, there are two kinds of treatment:

  • Brain surgery: The tumor is surgically removed. This helps to stop seizures in as much as 90% of people.
  • Anti seizure medication for brain tumors: Certain anti-epilepsy drugs have been shown to be most effective for helping control seizures in people with brain tumor-related epilepsy. Levetiracetam and valproic acid are the most widely used.

Around one in three people with epilepsy find that their seizures are not controlled with anti epileptic drugs – this is called refractory epilepsy.

What Is An Epileptic Seizure

PPT

Your brain normally works by sending small, controlled electrical signals between billions of cells in your brain. An epileptic seizure happens when thereâs a sudden discharge of electricity that puts those signals out of balance. It can cause you to lose consciousness or behave in unusual ways.

Memory Loss And Confusion

Memory problems can be due to a tumor in the frontal or temporal lobe. A tumor in the frontal or parietal lobe can also affect reasoning and decision-making. For example, you may find that:

  • Its hard to concentrate, and youre easily distracted.
  • Youre often confused about simple matters.
  • You cant multitask and have trouble planning anything.
  • You have short-term memory issues.

This can happen with a brain tumor at any stage. It can also be a side effect of chemotherapy, radiation, or other cancer treatments. These problems can be exacerbated by fatigue.

Mild cognitive problems can happen for a variety of reasons other than a brain tumor. They can be the result of vitamin deficiencies, medications, or emotional disorders, among other things.

Vomiting: Persistent And Inexplicable

If you feel like throwing up or are actually throwing up without any problem in your digestive system, see if they occur with headaches or a problem in your vision.

Persistent vomiting or nausea, without any apparent reason, especially in the morning or when you change your position, can be a sign of a brain tumor. Vomiting is often a result of raised pressure inside the skull, which is why movement triggers it.

In a study on 111 brain tumor patients with primary and metastatic tumors, 40% complained of vomiting and nausea.5

This means that vomiting is a common sign across the various stages of brain tumor. It is usually thought to be a symptom of a tumor in the cerebellum. However, if it presents without other symptoms, we often misdiagnose vomiting as a symptom of a problem in the digestive system.

Salivary Gland Cancer Symptoms

Salivary glands make saliva and release it into the mouth. There are three major salivary glands:

  • Parotid glands

Symptoms for this type of cancer may include:

  • Painless lump in your ear, cheek, jaw, lip or inside of the mouth
  • Fluid draining from your ear
  • Trouble swallowing or opening mouth wide
  • Numbness or weakness in your face
  • Persistent pain in your face

People who undergo regular treatments for seizures often are compromised of a quality of life and also their independence. Grand mal seizure can be life threatening and pose many types of serious health disorders. Temporal lobe seizure is one such disorder. It involves unusual disturbances and sensations. It arises because of the abnormal electrical disturbances affecting temporal lobe located in the brain. Temporal lobes are the part of the brain that usually starts from the temples extending your ears. It is quiet pain bearing seizure and also life threatening if not treated at the initial level.

How Do I Know If A Seizure Is A Symptom Of A Brain Tumour

All seizures should be checked out by your GP or A& E doctors as they could be due to a serious condition including a brain tumour.

When people hear the term seizure, they often think of convulsive seizures. This is where the person loses consciousness, their body goes stiff and they fall to the floor with their limbs jerking. However, this type of seizure is rarely associated with brain tumours.

There are many other types of seizure. The type most commonly associated with brain tumours are called focal seizures.

Focal seizures affect only one part of the brain and can affect your movement and/or your level of consciousness or awareness.

The symptoms you have will be different according to where the seizure starts in the brain.

The following are examples of what can happen you may experience something different.

Symptoms of a focal seizure include:

Focal aware seizures

A small part of one side of the brain is affected. Youll remember the seizure afterwards, even if you cant describe it. Symptoms include:

Focal impaired awareness seizures

A larger part of one side of the brain is affected. Your consciousness is affected you may be confused, unaware of what youre doing, and unlikely to remember what happened afterwards. Symptoms include:

  • visual disturbances, such as coloured or flashing lights
  • hallucinations .
  • Can Pituitary Tumors Cause Seizures In Dogs

    Then, can pituitary tumors cause seizures in dogs? Pituitary tumors may cause visual loss and other focal neurological signs due to the proximity of the gland to several cranial nerves. Large tumors may also result in an increase in intracranial pressure, and neurologic signs such as seizures and abnormal behavior are common.

    While brain tumors can occur in dogs of any age, most dogs who develop brain tumors are over the age of 5. What are the signs of a brain tumor? The most common sign of a brain tumor in a dog is seizures. Any time a new onset of seizures is observed in a dog 5 years of age or older, a brain tumor must be considered as a possibility.

    In dogs over age 5 or 6, new onset seizures are strongly indicative of a brain tumor. The first symptoms of a brain tumor will vary from dog to dog. In the case of my parents German shepherd, the symptoms were:

    Brain tumors are a common cause of seizures in older dogs. They can be primary or secondary in our furry friends, meaning they either originate in the brain, or they are a result of metastasis. When a senior dog has a brain tumor, this can cause a disturbance in the normal activity within the brain.

    Tumors can be malignant and may also put pressure on the brain as it grows, causing loss of vision, motor coordination and sometimes, seizures. Cancer growths in dogs can form on the brain or the pituitary gland, and can affect

    Seizures And Memory Networks

    2016 study in rats looked at how seizure-like activity impacted memory consolidation. Memory function can be affected in some types of epilepsy, including temporal lobe epilepsy.

    Memory consolidation normally happens during sleep and involves small ripples of activity in the hippocampus, the area of the brain concerned with memory.

    These ripples can be followed by activity in the prefrontal cortex, an area involved in higher-level cognitive functions.

    In people with temporal lobe epilepsy, short bursts of electrical activity called IEDs can happen between seizures. The researchers wanted to see if these abnormal bursts of electrical activity impacted memory in rats. They found that:

    • Stimulating IEDs in rats led to impaired memory in a maze-solving activity.
    • The effect on memory increased with the amount of IEDs that a rat experienced.
    • IEDs beginning in the hippocampus were followed by electrical activity in the prefrontal cortex. This happened while the rats were both asleep and awake.
    • A similar pattern of activity was seen when observing 4 individuals with epilepsy and IEDs.

    The researchers believe that IEDs can disrupt normal signaling for memory consolidation. In short, IEDs from the hippocampus may impact how the prefrontal cortex responds to signaling from this area, potentially affecting memory.

    Controlling Seizures In People With Brain Tumors

    Seizures (epilepsy) and brain tumours

    Whether a person with a brain tumor has had one or 100 seizure episodes, controlling and preventing seizure activity is an essential part of their treatment.

    In most cases, the seizures themselves do not pose a great health risk environmental hazards are of greatest concern.

    Seizures don’t discriminate and can occur at any time, leading to possible injury of the person seizing and to those around them. There is concern about people seizing during routine activities like driving or bathing. Plus, there is a heightened risk of head injury from falling during an episode.

    Does Type Of Epilepsy Play A Role

    There are many different types of seizures, all with different characteristics. According to the National Institute of Neurological Disorders and Stroke, doctors have identified over 30 different types of seizures.

    As such, research findings may not translate across different seizure types. For example, whats true for someone with temporal lobe epilepsy may not be true for an individual with a different type of epilepsy.

    The effectiveness of medications may also play a role. For example, someone whose seizures can be managed using antiseizure medications may not experience the same effects as an individual with epilepsy whos body is resistant to medications.

    Seizures As A Presenting Sign And Their Relation To Survival

    New-onset seizures often represent the first clinical symptom for each type of brain tumor and are often the only clinical sign in neuroglial tumors. More benign gliomas show a higher frequency of seizures than malignant gliomas. Neurogliomas and gangliogliomas have a seizure incidence of 80%100%, oligodendrogliomas of 70%90%, diffuse low-grade gliomas of 60%85%, and glioblastomas of 40%60% . In GBMs, 40% of patients present with epilepsy, and 20% develop seizures later on . Epilepsy as a presenting symptom implies a favorable prognostic factor for duration of survival in both low- and high-grade gliomas .

    In general, the seizure type in brain tumors is characterized as partial or localization-related epilepsy, and varies between simple partial in 23%58%, complex partial in 7%31%, and secondary generalized seizures in 10%68% . Generalized seizures are often seen as the early warning sign of seizures in about half the cases, and partial seizures without loss of consciousness dominate in the case of persisting seizures .

    A recurrence or worsening of seizures following first-line antitumor therapy heralds progression of GBMs in approximately two thirds of patients . In low-grade gliomas, this association is less evident .

    A recurrence or worsening of seizures following first-line antitumor therapy heralds progression of GBMs in approximately two thirds of patients. In low-grade gliomas, this association is less evident.

    Cancer of the ear is quite rare and most often develops in the outer skin. The condition can affect any of the three parts of the ear the inner, middle or outer ear. But what are the symptoms that one should keep in mind for this rare condition. Ear cancer symptoms vary, depending on where in the ear the tumour is located.

    The main outer ear cancer symptom is a spot that does not heal within four weeks, according to Express.co.uk. The spot may appear like a pink lump, with hard scaly surface. They often bleed easily. Hearing loss and earache could be signs of middle ear cancer. Hereâs how you can relieve ear acne in kids.

    What Is A Glomus Tumor

    Glomus tumors also known as paragangliomas of the head and neck are benign but locally invasive tumors that arise from glomus cells.

    In the head and neck, glomus tumor tissue is found in the jugular bulb, middle ear, and carotid artery. Of these sites, tumors are most common in the jugular bulb, which is a region of the jugular vein positioned immediately below the middle ear. These glomus tumors may grow into the middle ear and brain.

    Tumors originating in glomus cells of the middle ear are called glomus tympanicum tumors. Glomus tympanicum tumors are the most common vascular tumors of the middle ear.

    Glomus tumors may also arise in deep neck space along the course of the vagus nerve. These are called glomus vagale tumors.

    Glomus tumors are highly vascular and usually solitary.

    Because they are usually benign and slow-growing, mortality rates are low . However, their growth can cause significant damage to surrounding tissue and nerves.

    Common symptoms of glomus tumors are hearing loss and facial palsies.

    At UPMC, the preferred treatment is a transmastoid surgical approach to remove the tumor.

    In addition, Gamma Knife® radiosurgery may be used as the first treatment option or as an additional treatment after surgery.

    Gamma Knife radiosurgery is a painless procedure that uses hundreds of highly focused radiation beams to target tumors and lesions within the brain, with no surgical incision.

    Grand mal seizures experienced from the seizure caused in the temporal lobe is usually very freighting. Patient experiences a lot of pain and requires serious medical attention to help him to recover from the attack. Temporal lobe seizures apart from grand mal seizure attack may also invoke partial and complex partial seizure attacks. Patient who experiences complex partial seizure also experiences grand mal seizure, when a patient experiences grand mal seizure arising out of partial seizure they are known as the secondary generalized seizures and if they are repetitive in nature it leads to epilepsy the dangerous form of seizures.
