Alzheimers And Epilepsy: Intimate Connections
At first blush, Alzheimers disease and epilepsy may appear to be nothing alike. The former occurs in older people and involves memory issues and other cognitive problems the latter is characterized by seizures and affects people of all ages.
But the two conditions overlap in many ways. Both can involve problems with spatial memory and navigation, lowered glucose metabolism, cellular death and degeneration in the brains temporal lobe, and damage to the hippocampus.
Like people with Alzheimers disease, people with epilepsy can experience memory loss or confusion. As part of an aura, they may hear or see things that arent there. When older adults display these symptoms, they may be misdiagnosed with Alzheimers disease, when in fact they are having a seizure. In older adults without a history of epilepsy, seizures are often nonconvulsive: The person may simply stop and stare for a few moments or become confused.
The parallels between epilepsy and Alzheimers disease are quite striking, said Andrew J. Cole, professor of neurology at Harvard University and head of the epilepsy group at Massachusetts General Hospital. Its surprising there hasnt been more collaboration between the Alzheimers and epilepsy communities.
The conditions also appear to be associated. People with Alzheimers disease have a high risk of developing seizuresmore than 80 times the risk of people who dont have Alzheimers.

Memory Loss Cause # 9 Brain Tumors
Current research studies show that over fifty percent of all cancer cells clients exhibit signs and symptoms of memory loss that can be confused with dementia- 90% of these signs and symptoms were connected to spoken memory and how rapidly the study individuals might bring up memories as well as solve problems. Study shows that chemotherapy can directly cause cognitive disability, but it is extensively recognized that memory loss and also cancer cells are both complex concerns that more most likely have a number of reasons, rather than just one medicine.
Some symptoms of brain problems that show you need to see a specialist include:.
Abrupt or severe sight issues, like double and blurred vision.Seizures.Wooziness.Problem strolling as well as talking.Sudden significant modifications in the detects, like scenting something that isnt there and also hearing points .Unusual vomiting.
How Are Seizures Diagnosed
Your healthcare provider will ask about your symptoms and your health history. Youll be asked about other factors that may have caused your seizure, such as:
Drug or alcohol use
Blood tests to check for problems in blood sugar and other factors
Imaging tests of the brain, such as an MRI or CT scan
Electroencephalogram, to test your brain’s electrical activity
Lumbar puncture , to measure the pressure in the brain and spinal canal and test the cerebral spinal fluid for infection or other problems

How Long Does Memory Loss Last After A Seizure
Short-term memory loss after a seizure is quite common sufferers may not remember where they are or what they were doing sometimes, complete amnesia can occur for periods of up to an hour. Eventually, reoccurring seizures can cause damage to the memory areas of the brain and result in permanent memory loss.

Can A Dog Get Brain Damage From A Seizure
The short answer is yes, but its not common. Seizures are generally short-lived, lasting a few seconds to a few minutes. As such, they have little lasting effect on the brain. However, multiple seizures over a short period of time called cluster seizures can result in brain damage.
Dogs who suffer from Idiopathic Epilepsy are most in danger for multiple seizures, and should be monitored closely during and after the initial seizure. When a dog has a seizure, his body temperature rises. When seizures are clustered together, the dogs body temperature can remain elevated for extended periods of time, which can cause brain damage and other health issues.

How Do Seizures Affect Executive Function
Seizures that happen in the frontal lobe can cause your planning ability to become weaker. You may not be able to organize your thoughts or your actions in the best way. If you are making a shopping list, for instance, you may think or write the same item over and over.
It may be harder for you to interact with people. Your attention may drift much sooner than before. Some people say their personality has changed after having seizures for many years. It also may be harder for you to stop unwanted behavior. You may say whats on your mind even when its not the right time. For example, it is probably not a good idea to say that you hate your boss when youre in the middle of your annual performance review, unless youre willing to deal with the bosss reaction.

Key Points About Epilepsy And Seizures
A seizure occurs when one or more parts of the brain has a burst of abnormal electrical signals that interrupt normal signals
There are many types of seizures. Each can cause different kinds of symptoms. These range from slight body movements to loss of consciousness and convulsions.
Epilepsy is when you have 2 or more seizures with no known cause.
Epilepsy is treated with medicine. In some cases, it may be treated with VNS or surgery.
Its important to avoid anything that triggers seizures. This includes lack of sleep.

Conditions That Cause Memory Loss
Memory loss isnt always the result of a severe condition. Sometimes, having a lot on your mind or daily stress can send your mind into a tailspin. However, if you continually forget things, several conditions may be the culprit, including:
- Brain infections
- Oxygen deprivation
Sometimes, memory loss is a symptom of a much bigger problem, such as those listed above. Its often the first symptom of dementia. This condition is characterized not only by changes in memory but also decreased problem-solving and language skills. There are four types of dementia that are unable to be cured. They include:
- Alzheimers disease
- Lawyer body dementia
- Frontotemporal dementia
Dementia usually continues to worsen as time goes by. It can cause many different symptoms other than memory loss, such as:
- Trouble concentrating
- Difficulty with problem-solving skills
It may also affect your personality and can cause behavioral changes. If you or someone you love starts exhibiting any of these symptoms, it may be time to see Dr. Mehta for an evaluation.
Mesial Temporal Lobe Epilepsy And Memory
Much of our knowledge regarding memory impairments in intractable epilepsy comes from preoperative and postoperative neuropsychologic testing of people being considered for surgery to treat intractable mesial temporal lobe epilepsy. Deficits in visuospatial or verbal memory measured with traditional neuropsychologic testing can help localize dominant or nondominant hemisphere dysfunction.29,30 Hippocampal volume loss has been correlated with verbal memory loss seen in people with dominant hemispheric temporal lobe epilepsy.31,32 Unfortunately, postoperative memory decline is greatest in individuals with higher verbal memory scores on presurgical evaluation.33
The reliability of visual memory deficits as a distinct sign of nondominant hemispheric dysfunction is more complex.34 This is related to visuospatial memory processing in people with chronic mesial temporal lobe epilepsy and the global dysfunction associated with the disease. In some patients intracarotid amobarbital testing may be needed to confirm lateralization of language and memory and predict postoperative memory change in individuals undergoing mesial temporal lobe resection.35

What Is The Outlook For Patients With Temporal Lobe Epilepsy
Most patients with epilepsy can enjoy successful and productive lives. Medication is successful in controlling seizures in about two-thirds of patients with temporal lobe epilepsy. For the other third, surgery helps about 70 percent of patients become seizure free. If surgery doesnt work or if the patient is not a candidate for surgery, electrical brain stimulation devices can be tried.
In rare cases, epilepsy can be fatal. About one in 1,000 people with epilepsy die each year from what is called Sudden Unexpected Death in Epilepsy . The cause is not known, but having a lot of seizures increases the risk. Its more common in adults than children. Another way seizures can lead to death or serious injury is by causing a person to have an accident while driving or operating heavy equipment.
Transient Epileptic Amnesia: A Treatable Cause Of Spells Associated With Persistent Cognitive Symptoms
- Department of Neurology, Mayo Clinic-Rochester, Rochester, MN, United States
Objective: To characterize the clinical, EEG, and neuroimaging profiles of transient epileptic amnesia .
Methods: We performed a retrospective analysis of patients diagnosed with TEA at the Mayo Clinic Minnesota from January 1, 1998 to September 21, 2017. Diagnostic criteria included the presence of recurrent episodes of transient amnesia with preservation of other cognitive functions and evidence for epilepsy .
Results: Nineteen patients were identified with median onset age 66 years and median time to diagnosis 2 years. Thirteen patients reported persistent cognitive/behavioral symptoms, including 4 for whom these were the chief presenting complaints. EEG revealed epileptiform abnormalities involving the frontal and/or temporal regions in 12/19 individuals , including activation during sleep in all of these cases. In numerous cases, sleep and prolonged EEG evaluations identified abnormalities not previously seen on shorter or awake-state studies. Brain MRI revealed focal abnormalities in only 4/19 cases . FDG-PET identified focal hypometabolism in 2/8 cases where it was performed, both involving the frontal and/or temporal regions. Anti-seizure therapy, most often with a single agent, resulted in improvement in all 17 cases with available follow-up.

Epilepsy And Memory Loss
Learn about the link between epilepsy and memory loss. We explore seizure memory loss, the influence of medication and feelings of stress and tiredness.
There is nothing worse than being unable to remember something important just when you need it. And for people who live with seizures, the link between epilepsy and memory loss can be especially frustrating.
If you have ever found that you struggle to remember things or miss appointments because youâve forgotten, epilepsy could be part of the reason. So, can seizures cause memory loss and what should you do if you think your epilepsy is making you forgetful?
Treatment Of Interictal Memory Disorders
- Improving seizure control, reducing or eliminating AEDs that affect cognition , and improving sleep habits help memory in some patients.
- Pragmatic approaches include use of visual imagery, lists and schedules , learning to take simple and clear notes, small portable notepads organized by topic, carrying important telephone numbers and addresses, and use of alarms as reminders. These strategies often fail to fulfill the needs of higher-functioning patients with demanding jobs.
- No medications are proven to enhance memory in patients with epilepsy.
- Studies on dietary supplements and herbal products to treat memory have shown mixed results. Most of the studies have been done in older people or those with Alzheimer’s disease or other dementias. Since some of these can also have dangerous side effects, it is important for people with epilepsy to talk to their epilepsy team before considering any over-the-counter or prescribed supplements or herbal products.

In Epilepsy Seizures Are Often Frightening What Happens Afterward Can Be Worse
Newswise Seizure control is the primary driver of epilepsy treatment. For many people with epilepsy, however, the seizures themselves are secondary its the after-effects of the seizures that dramatically affect their lives.
More than 70% of people with epilepsy report post-ictal complications, including confusion, fear, exhaustion, headache, emotional reactivity, memory problems and behavioral changes. Some last an hour others can last for days.
With a few exceptions, there are no treatments for post-ictal complications, other than preventing the seizures that precede them. And little is understood about why they occur.
Victoria Barker, a 30-year-old Canadian, was diagnosed with epilepsy at 21. She has absence seizures during the day, and tonic-clonic seizures at night. During the first year of her seizures, the post-ictal period was soothing. I experienced an inability to speak and confusion about my surroundings, but it was extremely peaceful, like I’d just woken up from a good nap, she said.
Then the feelings changed. Her current post-ictal state encompasses frustration, confusion and fear.

Memory Problems And Education
A study of school children with active epilepsy in West Sussex found that over half of the children had problems with memory. If your child has memory problems they may find learning more difficult, and may need extra support at school to help them remember what they are being taught. If you feel your child may have memory problems you should discuss these issues with the school. We have more information about epilepsy in schools.
If you are in higher education and have memory problems, you could speak to the college or university disability advisor about adjustments to help you. This could include recording lectures or being given extra time in exams. We have more information about epilepsy in higher education.
The disability support services at my university provided me with a dictaphone and I was able to record all my lectures. I also would use my phone to record myself, and then right up to an exam I would put my headphones in and listen to myself right up until the exam door.
For a tough exam last year I spent a while changing catchy song lyrics to facts and theories and then listened on repeat. It definitely helped!
When To See A Doctor
It is important for a person to see a doctor if they experience a seizure that results in an injury. They should also seek medical advice if they have more than one seizure within 24 hours.
A person should see a doctor after their first seizure. They will be able to diagnose any underlying conditions and prescribe treatment, if necessary.
It is important to seek immediate medical treatment if a person severely injures themselves, has a seizure in water, or has an underlying health condition.

We had to design a very conservative study that takes these participants out, said Ophir Keret, a neurologist at the University of California, San Francisco who was a researcher on both studies, because we wanted to isolate the effect that epilepsy would have.
Michela Gallagher, a professor of psychology and neuroscience at Johns Hopkins University, said the researchers used good criteria for defining unprovoked seizures independent of things that could be causing , and pointed to the large sample size and long time period for tracking each veterans health trajectory as two of the studys strengths. One weakness she noted is that the Veterans Affairs health data used in the study did not allow researchers to differentiate between Alzheimers or other types of dementia. Neither the veterans study or the smaller one has been published yet in a peer-reviewed journal.

How Is Temporal Lobe Epilepsy Diagnosed
Your doctor will ask questions about your medical history and about your seizures how long they lasted what you felt before, during, and after the seizure where you were and what happened before the seizure started, and if something seemed to trigger the seizure . The doctor might also want to talk to people who were with you during a seizure to gather their observations.
Tests that are used in diagnosing epilepsy include an MRI to look for tumors or other structural problems in the brain and an EEG , which measures electric activity in the brain. Other brain scanning tests include:
- A single photon emission computed tomography , which shows blood flow to the brain to help locate the site of the seizure.
- An ictal SPECT, which locates the area of the brain where seizures are occurring.
- A positive emission tomography scan, which looks at brain metabolism to identify where seizures start.
Blood samples are also taken to screen for genetic disorders or other health conditions that could be causing the seizures.
