Finding The Cause Of Memory Loss

Silent Strokes Tied to Memory Loss Among Older Adults

If you find that you are increasingly forgetful or if memory problems interfere with your daily life, schedule an appointment with your doctor to determine the cause and best treatment.

To evaluate memory loss, your doctor will take a medical history, perform a physical exam — including a neurologic exam — and ask questions to test mental ability. Depending on the results, further evaluation may include blood and urine tests, nerve tests, and imaging tests of the brain such as computerized axial tomography scans or magnetic resonance imaging .

You may also be sent for neuropsychological testing, which is a battery of tests that help pinpoint the memory loss.

When Should I Call The Doctor About Stroke

Some slowing of thinking processes is normal in aging. However, any change in thinking, memory, reasoning, attention, grooming, behavior, or personality that interferes with your ability to care for yourself, maintain health and safety, or participate in activities that you enjoy warrants a visit to your health care provider.

An early diagnosis allows treatment to begin earlier in the disease, when it has the best chance of offering significant symptom relief. Early diagnosis also allows you to plan activities and to arrange for care while you can still take part in making decisions.

  • Holter monitoring – Detects heart rhythm disorders
  • Carotid duplex Doppler ultrasound – Detects blockage of the carotid arteries, the main arteries leading to the brain
  • Lumbar puncture – under sterile conditions, fluid is removed by placing a needle into the spinal canal. The patient is given a local anesthetic prior to the removal. The fluid is sent for special tests after the opening pressure is measured. This may be done depending on the symptoms that the patient presents to the physician.

Tests may also be done to rule out other causes of dementia.

  • Electroencephalogram – Detects abnormal electrical activity in the brain
  • Cerebral angiography – Not used routinely in the evaluation of vascular dementia but sometimes used to detect vascular conditions, including stroke

What Is Vascular Dementia

Vascular dementia is the second most common form of dementia after Alzheimer’s disease. It’s caused when decreased blood flow damages brain tissue. Blood flow to brain tissue may be reduced by a partial blockage or completely blocked by a blood clot.

Symptoms of vascular dementia may develop gradually, or may become apparent after a stroke or major surgery, such as heart bypass surgery or abdominal surgery.

Dementia and other related diseases and conditions are hard to tell apart because they share similar signs and symptoms. Although vascular dementia is caused by problems with blood flow to the brain, this blood flow problem can develop in different ways. Examples of vascular dementia include:

  • Mixed dementia. This type occurs when symptoms of both vascular dementia and Alzheimer’s exist.
  • Multi-infarct dementia. This occurs after repeated small, often “silent,” blockages affect blood flow to a certain part of the brain. The changes that occur after each blockage may not be apparent, but over time, the combined effect starts to cause symptoms of impairment. Multi-infarct dementia is also called vascular cognitive impairment.

Researchers think that vascular dementia will become more common in the next few decades because:

How Is Memory Affected

What stroke does to memory depends on where and how the stroke injured the brain plus the overall health of the patient. Each side of the brain controls different things. A stroke on one side of the brain will cause different problems than a stroke on the other side. This means that memory loss will not be the same for each stroke patient. Two types of memory that can be affected by stroke include the following:

  • Verbal memory memory of names, stories and information having to do with words

  • Visual memory memory of faces, shapes, routes and things seen

8 Reasons A Stroke Happens (That Most People Ignore)

Comments from members of our Research Network:

‘I would support this project due to the increase in life expectancy of those experiencing a stroke and the higher risk of developing dementia post stroke.’

‘Post stroke dementia must surely be on the increase. This work may well help to prevent this.’

‘Building on knowledge already discovered.’

What Does This Project Involve

This project will involve looking at biological events that happen inside brain cells after a stroke that can lead to dementia. Scientists based in Sheffield and Newcastle universities will use brain tissue donated for an existing study called the Cognitive Function After Stroke Study. This sample includes the brains of people who had dementia after stroke and those that did not.

The researchers will examine the health and appearance of blood vessels and brain cells in these brains. Subtle signs of damage to brain cells will be found by looking at them with a cutting-edge microscope. Dr Wharton and his team will examine the messages that were sent around different types of brain cells carried by dedicated messengers. For example, was the brain cell trying to repair itself after a stroke? Or was the cell going into an auto-destruct mode?

In particular the researchers will focus on the health and messaging of astrocytes. The research team will find out what the astrocytes were doing after stroke by cutting them out of the donated brain tissue using microscopic lasers. This means that they will be able to be certain that they are looking at only astrocytes and not mixing it up with information from other cells. The team will closely examine the astrocytes for signs that it was trying to repair itself or self-destruct.

Memory Loss Cause #11 Anxiety

Somewhat, stress and anxiety can help your memory, Legendre says. Mild or moderate anxiety thats short-term can be practical for motivation and also focus. Study at the Montreal Centre for Studies on Human Stress has revealed that we require stress hormones for optimal mind feature. Both ends of the continuum too little stress and anxiety, or as well much can harm your memory. Contrary to what we may assume, not having enough stress hormones can be as poor for your memory as having too much, Legendre says. When stress and anxiety hormonal agents like cortisol as well as adrenaline run out equilibrium, we can be absent-minded. At the workplace, be aware of the signs that your stress is reaching the point of exhaustion. It comes to be more challenging to remember brand-new info, maintain it long-lasting, as well as to keep in mind occasions from long ago. time.Learn more about Can Heat Stroke Cause Memory Loss in this article.

To limit exactly how stress affects your concentration and also memory, Legendre recommends building mindfulness practices into your day. Attempt meditation for a few minutes every day. These techniques help you recognize the here and now moment and focus on what youre doing, she says.

How Can I Prevent Stroke

In many cases, vascular dementia is preventable. Risk factors for stroke and vascular dementia include high blood pressure, high cholesterol, heart disease, smoking, and diabetes. For many people, risk can be reduced by adopting a healthy lifestyle. People who have had a stroke may be able to reduce their risk of further strokes by drug treatment or surgery in addition to adopting a healthy lifestyle.

What Part Of The Brain Can Cause Memory Loss

Amnesia can result from damage to brain structures that form the limbic system, which controls your emotions and memories. These structures include the thalamus, which lies deep within the center of your brain, and the hippocampal formations, which are situated within the temporal lobes of your brain.

The Capacity Of Short

Your short-term memory has a limited capacity. Certain studies conducted by the famous George Miller in the 1950s are often used as the guideline for determining how much capacity the short-term memory has. It is estimated that working memory can hold five to nine items at a time. However, newer studies have shown that in different age groups, the number is much lower, around four to five items.

The type and characteristics of the information also make a difference in how much can be stored in short-term memory. There have also been studies that have shown that short-term memory capacity and how long information remains in short-term memory can be increased if the information is said aloud.

Memory Problems Can Be Caused By Stroke

Suffering a stroke can impair a persons memory for weeks, months, or even years. Sometimes, a person evaluated for memory loss is found to have suffered minor strokes they werent even aware of, says Mohini Gurme, MD, a neurologist with Rockland Neurological Associates in West Nyack, NY. For Stroke Awareness Month, in May, Dr. Gurme explains why its important to get evaluated early for memory loss caused by stroke or other conditions.

The National Stroke Association estimates that approximately one third of stroke survivors will develop memory problems. Whether a person who has had a stroke suffers memory loss or other cognitive problems has to do with where in the brain the stroke occurred, as well as other factors including a persons age, Dr. Gurme says. She notes memory problems are more common in elderly stroke survivors.

In addition to affecting memory, a stroke can impair a persons processing speed and ability to multitask, Dr. Gurme said. When a person comes in complaining of memory problemsor their loved one brings them inDr. Gurme will ask the person and their loved ones about their day-to-day functioning. Are they forgetting things, getting lost while driving, having trouble cooking meals, or missing making payments on their bills? Often the people around the patient are the ones who notice the memory loss, not the patients themselves, she says.

Vascular Dementia Signs And Symptoms

PPT

Vascular dementia affects different people in different ways and the speed of the progression also varies from person to person. Some symptoms may be similar to those of other types of dementia and usually reflect increasing difficulty to perform everyday activities like eating, dressing, or shopping.

Behavioral and physical symptoms can come on dramatically or very gradually, although it appears that a prolonged period of TIAsthe mini-strokes discussed aboveleads to a gradual decline in memory, whereas a bigger stroke can produce profound symptoms immediately. Regardless of the rate of appearance, vascular dementia typically progresses in a stepwise fashion, where lapses in memory and reasoning abilities are followed by periods of stability, only to give way to further decline.

Common Signs and Symptoms of Vascular Dementia
Mental and Emotional Signs and Symptoms
  • Slowed thinking
  • Language problems, such as difficulty finding the right words for things
  • Getting lost in familiar surroundings
  • Laughing or crying inappropriately
  • Difficulty planning, organizing, or following instructions
  • Difficulty doing things that used to come easily
  • Reduced ability to function in daily life

Can A Pons Stroke Heal

Typically, if the stroke was small, you can recover within about 6 months. If the stroke was massive, then recovery can take years. Again, every stroke is different so its possible to have a very fast recovery from a massive pontine stroke just as its possible to recover slowly from a minor stroke.

What Is The Risk Of Vascular Dementia After Stroke

Vascular dementia could be caused by a stroke or other conditions that impact the supply of blood in the brain, such as poor circulation.

A persons risk of post-stroke dementia increases with the number of strokes they experience. For example, a large study of over 5,000 stroke survivors found that the rate of vascular dementia was around 9% in those who had only suffered one stroke. In those who had experienced more than one stroke, however, the rate increased to 25%. The risk of vascular dementia also increases with age.

Because a stroke is a vascular disease that impacts the arteries, the same factors that increase the risk of stroke also increase the risk of vascular dementia. This means that conditions like high blood pressure, diabetes, and high cholesterol all increase the risk of vascular dementia.

Not all strokes cause vascular dementia, though. Every stroke is different and every person experiences different effects following a stroke. For example, a massive stroke may cause paralysis while very mild strokes may not cause any noticeable secondary effects at all.

However, just because a person does not experience many effects after a stroke does not mean they wont develop vascular dementia. The best way to reduce the risk of vascular dementia is to improve the health of your arteries and blood flow by managing any vascular diseases such as hypertension and diabetes.

Can Having A Stroke Increase Your Risk For Vascular Dementia

Vascular dementia can make it difficult for you to process information. Although its a common post-stroke problem, not everyone who has a stroke is at risk for vascular dementia. Your risk depends on the location and severity of your stroke. Your age, sex, and family history are also factors.

In a 2012 study, one researcher reviewed nine studies on dementia in people whove had a stroke. In total, the study looked at 5,514 people with pre- or post-stroke dementia. The study found that rates of post-stroke dementia were between 9.6 and 14.4 percent in people whove had one stroke. This rate increased to 29.6 to 53.1 percent in people with recurrent stroke.

Its worth noting that adults over age 65 who have a high risk of stroke also have a high risk of dementia unrelated to stroke. In the same 2012 study, it was determined that stroke is a risk factor for dementia, and dementia is a risk factor for stroke.

Rates from 9 studies show that about 10 percent of people whove had a stroke will develop dementia within the first year after the stroke.

Diabetes-Induced Memory Loss: Signs And Prevention | FYI

Write things down

Use calendars or diaries to keep track of appointments and important dates. You can also use them to record things that happened that day. Make a note of small tasks as you do them, so that you know if youve fed the cat or phoned someone. Write short notes after youve spoken with someone. If you do this after a therapy session, doctors appointment, or even a chat with a friend, you can go back and remind yourself of what you talked about the next time you see them.

Use prompts

Set your phone or a cooking timer to remind you when you need to take your medication. Leave things like your keys or wallet near the front door, so that youll see them when you go out. Add pictures of people next to their details in your contact book, to help you remember who they are. A pill or dosette box can help you to organise the medication you need to take each day, so you can easily see whether youve taken it or not. Most pharmacists will sort your medication into special packs for you now, so you know what you need to take each day. I carry a notepad and write down everything important Ive done or been told so I dont forget. Elizabeth

Put reminders where you wont miss them

Leave notes in noticeable places. Buy a pen that you can use to write on your bathroom mirror, or set up a white board somewhere obvious. You could put up signs in the kitchen to remind you to turn the cooker off, or one on the back of the door to remind you to lock it when you go out.

Vascular Dementia Vs Alzheimers Disease

Oftentimes, when someone hears the word dementia, they think of the type of dementia that results from Alzheimers disease. Vascular dementia is different from Alzheimers, although many people experience both types simultaneously. While vascular dementia is caused by impaired blood flow to the brain, Alzheimers is believed to be caused by improperly functioning proteins within the brain. Another important distinction between the two types of dementia is the rate of progressionthe symptoms of vascular dementia usually tend to appear more suddenly than the symptoms of Alzheimers.

Physical Trauma And Memory Loss

Physical trauma can greatly affect your memory, especially if brain damage occurs as a result of the injury. Physical trauma such as a head injury or stroke can damage the brain and impair a persons ability to process information and store information, the main functions of memory.

Another form of brain damage that directly affects memory is Wernicke-Korsakoff Syndrome, which is a consequence of chronic alcohol abuse. Wernicke-Korsakoff Syndrome is a combination of two disorders: Wernickes Disorder, in which poor nutrition damages the nerves in both the central and peripheral nervous system, and Korsakoffs Syndrome, which impairs memory, problem-solving skills and learning abilities. Severe injuries and physical trauma can also produce post-traumatic stress disorder, which can cause temporary memory loss to help a person cope with the traumatic event that caused the injury.

In the case of physical trauma, the length of memory loss depends on the severity of the injury.
