Five surprising causes of memory loss

Mind concept graphic for memory loss or alzheimer's diseaseAfter my husband had a surgical procedure that required anesthesia, not only did he wake up groggy, but his early stage Alzheimer’s disease worsened. He got lost driving in our home town and had more difficulty with everyday activities. Years later, it was a kidney stone that sent him over the edge into a downward spiral. It’s not a surprise that anesthesia can cause memory loss, temporary or permanent. But it came as a surprise when something as common as a kidney stone had a severe impact on my husband’s mental condition and overall health.

There is a link between common infections such as UTIs (urinary tract infections), the flu, colds, and stomach viruses and their effect on memory in the elderly and dementia populations. A significant study found that people with Alzheimer’s, who get even a mild respiratory or gastrointestinal infection, or a bump or bruise are at risk for having a significant, permanent memory loss, according to a report that was published in the September 8, 2009 issue of the journal Neurology. These patients can have high levels of tumor necrosis factor—alpha (TNF-a)—a protein that is linked to inflammation and is associated with memory loss and cognitive decline.

In the study done at the Clinical Neurosciences Research Division at the University of Southampton, United Kingdom, 222 Alzheimer’s patients were followed for six months. Of those, 110 people had an infection or injury that resulted in inflammation. These individuals had twice the memory loss during that period of time as the individuals who did not have an illness or injury. Researchers attribute the memory loss to inflammation. In patients whose TNF-a levels were high to begin with, an infection increased their memory loss to 10 times more than those who had low TNF-a levels. Clive Holmes, PhD, lead researcher, said that this population should be vaccinated against the flu, and infections and injuries should be treated as soon as possible.

Other surprising causes of memory loss

  1. UTIs–Urinary tract infections are notorious for causing delirium and delusional behavior in the elderly. When younger people get a urinary tract infection, they typically experience painful urination, an urgent need to urinate, lower abdominal pain, back pain on one side, and fever and chills. However, an older adult might not experience those symptoms. As we get older our immune system changes and it responds differently to infection. Instead of pain symptoms, seniors with a UTI may show increased signs of confusion, agitation or withdrawal. In older adults with dementia, these behavioral changes may come across as part of that condition or signs of advanced aging. If the underlying UTI goes unrecognized and untreated for too long, it can spread to the bloodstream and become life-threatening. In fact, I have a dear friend who recently died from a UTI that quickly became septic.
  2. Vitamin B12 is essential for normal nerve function. A deficiency can lead to confusion and dementia. It is vital to get 2.4 micrograms of B12 in your diet every day from sources such as dairy products, meat and fish, or from foods fortified with vitamin B12. Vegans must take a B12 supplement since the vitamin is found in animal foods.
  3. Sleep apnea causes one to stop breathing during the night. It can be very brief and very frequent, but it is treatable. Unfortunately, sleep apnea islinked to memory loss and dementia, according to Constantine Lyketsos, MD, director of the Memory and Alzheimer’s Treatment Center at Johns Hopkins Medicine and professor and chair of psychiatry at Johns Hopkins Bayview. You might have sleep apnea if you wake up with a headache and have daytime fatigue — or if your partner complains of loud snoring. A study published in The Journal of Neuroscience found that untreated sleep apnea affects spatial navigational memory. This type of memory includes being able to remember directions or where you put things like your keys. The research suggests that deep sleep, also known as rapid eye movement (REM) sleep, plays an important role in memory. Dr. Lyketsos explains that for people with sleep apnea, oxygen delivery to the brain is interrupted several hundred times during the night . He says, The brain is stressed, so people wake up, and the injury sleep apnea causes can show up as a variety of memory loss symptoms. If you or someone you know has sleep apnea, please make an appointment with your health practitioner.
  4. Some medications such as statins (cholesterol-lowering drugs), sleeping pills, antidepressants, anti-anxiety medications and some painkillers have been found to increase the risk for reversible cognitive side effects, including memory loss and confusion. A commonly prescribed type 2 diabetes drug, metformin, has also been associated with memory problems. A study published in Diabetes Care found that people with diabetes who took the drug had worse cognitive performance than those who did not take it.
  5. Thyroid disease can cause poor memory, especially in seniors. Hypothyroidism is very common in people over 60 and it steadily increases with age. It is believed that up to one in four individuals in nursing homes may have undiagnosed hypothyroidism. Memory loss or declining cognitive functioning which is frequently attributed to old age, might be the only symptom of hypothyroidism in an elderly person. If there is a family history of thyroid disease, past treatment for hyperthyroidism or a history of surgery and/or radiotherapy to the neck, a physician might be able to better establish a link leading to a diagnosis. Thyroid disease is a lifelong disorder that can be treated with medication, but the patient must be closely monitored to make sure the correct dosage is prescribed.

Tips for protecting your memory and keeping you and your loved one healthy and safe

  • Inoculate against flu, pneumonia and shingles
    Boost immunity with zinc, vitamin D and vitamin C

  • Reduce systemic inflammation with a curcumin (turmeric extract) supplement
  • Use a humidifier to moisturize nasal passages and mucous membranes to help keep them healthy
  • Engage in gentle exercise to reduce inflammation
  • Keep hydrated by drinking at least 6-8 glasses of water each day
  • Encourage seniors to use the bathroom several times a day, approximately every two to three hours.
  • Make sure the senior is maintaining good hygiene, with showers at least several times a week.
  • If the person is incontinent, make sure he or she changes undergarments frequently.

8 Ways to Train Your Brain

Intelligence of the human brain

Intelligence of the human brain

National Train Your Brain Day is observed annually on October 13. The observance was created to encourage all of us to exercise our brain and improve our cognitive skills. Doing word puzzles and number games, playing Bridge and reading are every-day activities that are good for the brain. But there are many other things you can do.

  1. Dance as though no one is watching. My book “Calmer Waters: The Caregiver’s Journey Through Alzheimer’s and Dementia” includes a 21-year-long study that was summarized in an article that appeared in the New England Journal of Medicine in 2003. The study found that when compared to 11 other activities including team sports, swimming and bicycling, dancing is the best activity for supporting cognition and staving off mental decline. In fact, the more complex the dance, the better it is for enhancing problem-solving skills and memory. You don’t have to be a great dancer. Just put on your favorite dance music and let loose in your living room. Or, find a dance partner and learn how to salsa, tango, or swing.
  2. Play an instrument. Numerous studies have indicated that listening to music and playing an instrument can reduce anxiety and depression and support cognitive functioning. Playing an instrument sharpens your concentration, boosts listening skills, and supports your time management and organizational skills. The efficacy of music therapy A Study done at the Auditory Neuroscience Laboratory at Northwestern University in Evanston, Illinois, and led by Nina Kraus, shows that musicians suffer less from aging-related memory and hearing losses than non-musicians. It is believed to be the first study to provide biological evidence that lifelong musical experience has a good impact on the aging process. Kraus says the research shows that playing an instrument helps hearing and memory, which is among the most common complaints from normal aging.
  3. Exercise! Dr. Monika Fleshner, researcher/professor at the University of Colorado, Boulder, and contributor to “Calmer Waters,” has spent her career showing that exercise is vital to reducing stress and supporting healthy mental function. “Physically active individuals are stress robust,” says Fleshner. “They demonstrate both stress resistance and stress resilience.” Exercise seems to buffer many of the deleterious consequences of stress, including poor memory. Scientists have also found that exercise encourages the growth of new brain cells in the hippocampus, the area that is crucial to memory and learning.
  4. Say it out loud. When I meet someone for the first time, I inevitably look in the person’s eyes and don’t even listen to their spoken name. As a result, I rarely remember the person’s name. Next time, I will heed the expert advice of repeating the person’s name. This is considered the easiest way to remember everything from where you put your keys to your grocery list. Say it out loud to yourself, or mouth the words, in order to remember quickly.
  5. Get a good night’s sleep. According to a study published in the journal Neuroscience (June 30, 2005) sound sleep triggers changes in the brain that help to improve memory. New memories are formed within the brain when a person engages with information to be learned (for example, memorizing a list of words or mastering a piano concerto). However, these memories are initially fragile. In order to “stick” they must be solidified and improved. This process of “memory consolidation” occurs when connections between brain cells as well as between different brain regions are strengthened, and for many years was believed to develop merely as a passage of time. More recently, however, it has been demonstrated that time spent asleep also plays a key role in preserving memory. So, do your best to work on sleep hygiene. Unplug at least an hour before bed, soak in tub filled with Epsom salts, play soothing music, make sure the room is not too warm, etc. And, never go to bed mad.
  6. Doodle. In memory tests, doodlers performed 29% better than non-doodlers when asked to recall names and places, Experts say doodling doesn’t tax the mind and allows us to concentrate on the task at hand. It stops us daydreaming, too, which is distracting. The same theory holds for coloring in the beautiful new adult coloring books that have become popular the past several years.
  7. Learn something before bed. If you want to consolidate a memory go through the information right before you fall asleep. You’ll have few, if any, interfering memories so you’ll remember it the next day.
  8. Feed your neurotransmitters. These are the chemicals that allow your neurons to talk to one another. They are vital to memory, focus, learning, energy and happiness. Acetylcholine is the primary carrier of thought and memory, and if you don’t have enough of this important neurotransmitter, you will probably have memory and cognitive problems. For healthy acetylcholine production, make sure you’re getting the nutrients that it is made from. Dr. Dharma Singh Khalsa, author of Brain Longevity (Warner Books, Inc. 1997) and the president and medical director of the Alzheimer’s Research and Prevention Foundation in Tucson, Arizona, suggests supplementing with choline, which is present in high amounts in lecithin. Lecithin is available in capsule, granule, liquid, tablet and powder form. The recommended therapeutic dose is 2500 to 3000 mg. four times a day, for a total daily dose of 10,000 to 12,000 mg. In addition, it’s important to take 1000 mg. vitamin C, three times a day, along with 100 mg. of B5, which are needed to transform lecithin into acetylcholine. It’s also advisable to take B6 and zinc, which help in the synthesis of acetylcholine. The nutrient DMAE (dimethylaminoethanol) helps build acetylcholine levels. It is present in your brain in small quantities, and is also found in seafoods, including sardines. Since it is stimulating to the central nervous system, Dr. Khalsa suggests starting out with a low dose of about 40 mg. twice a day, and building up to 200 mg. daily, if you don’t feel overstimulated. 

 

 

 

 

 

How Does Food Affect Your Mood?

If you are a caregiver you are undoubtedly stressed. And people who are stressed typically crave and overeat soda, candy, chips, cookies, bread, pasta and icecream for a temporary lift. The problem is that eating refined carohydrates will give you a temporary fix, but your blood sugar will crash a couple hours later, leaving you tired and moody.

Bad Habits=Poor Food Choices

Along with craving refined carbs, caregivers often eat on the run—standing up, in the car, chowing down, or going through the “drive thru” lane at your favorite fast food restaurant. Do you grab a candy bar in the afternoon for a “pick-me-up”? Do you skip breakfast and grab a doughnut or bagel and coffee? Do you drink soda instead of water? Don’t feel guilty if you answered “yes” to any of these questions. It’s typical—but it’s not healthy.

Here’s a better way to reduce your stress

Neurotransmitters are the chemicals in the brain that allow neurons to communicate. They are supported by nutritious foods and are depleted by lack of sleep, poor eating habits, and certain drugs and environmental toxins. The important thing that caregivers need to know is that we can support our neurotransmitters with healthy eating habits. In turn, our neurotransmitters will help support our mood, energy, ability to sleep well, and perform at our best.

Here are the most important neurotransmitters and the foods that support them

1. Serotonin is necessary for a stable mood.

A deficiency can result in:

  • Depressed or irritable mood, sudden tears
  • Insomnia and anxiety
  • Binge eating
  • Overactive mind
  • Low tolerance to stress
  • Decreased immune function

Foods that enhance serotonin: Soy, turkey, cheese, cottage cheese, avocado, meat, comfort food (mashed potatoes, macaroni and cheese)

2. Dopamine keeps us focused and motivated.

A deficiency can result in:

  • Depressed mood
  • Excessive sleeping
  • Weight gain, obesity
  • Lack of energy
  • Lack of enjoyment
  • Low libido
  • Nicotine addiction

Foods that enhance dopamine: Meat, wild game, eggs, chocolate, blueberries, yoghurt, milk, soy, cheese, seeds and nuts, beans and legumes

3. Norepinephrine is responsiblie for stimulatory responses in the body.

A deficiency can result in:

  • Depressed mood
  • Poor sleep
  • Fatigue, low energy
  • Poor memory/focus
  • Apathy

Foods that enhance norepinephrine: almonds, apples, avocado, bananas, beef liver, cheese, fish, green veggies, lean meat, nuts, grains, pineapple, poultry, tofu

4. GABA is responsible for helping us to relax and reduce anxiety.

A deficiency can result in:

  • High anxiety, panic, worry
  • “Monkey mind”
  • Difficulty falling and staying asleep

Foods that enhance GABA: Green tea, almonds, bananas, beef liver, broccoli, brown rice, halibut, lentils, oats, oranges, spinach, walnuts, whole grains

How to boost your neurotransmitters

  • Eat a serving of high-quality protein with every meal and snack. Focus on complex carbohydrates, and eliminate junk foods (refined carbs).
  • Enjoy unlimited amounts of fresh veggies.
  • Eat a good breakfast!
  • Eat 3 balanced meals and 1-2 healthy snacks per day.
